-> **RQ2-P3 gate RE-WORDED + RE-RUN GREEN — awaiting human freeze sign-off (§10) (2026-07-21,
-> operator-ruled).** Per overseer ruling, `rq2p3-mechanism-prereg.md` §7 items 1–2 were re-worded
-> pre-freeze (naive-funnel → mechanical-mix under the ratified posterior) + a §7 scope note added
-> (the gate validates the INSTRUMENT, must NOT pre-assert the H-vs-c sign — that stays the
-> two-sided confirmatory question). Deviation logged transparently in
-> `docs/stage-05-rq2p3-gate-clarification.md`. Re-run: **all four items PASS with real teeth** —
-> item 1 regressed on the FROZEN `bridge-federated` branch (unique sig → m_i=1 → H≈0, constant
-> c=1/C); item 2 B=1 → c=1.0 AND H=2.54 bits HIGH (maximal mix); items 3 (monotonicity) & 4
-> (entropy) PASS. Confirmatory H1/H2 direction-agnosticism UNCHANGED (no HARKing). **FREEZE STAYS
-> A HUMAN GATE:** §10 empty, no confirmatory RQ2-P3 cell runs until Andre records the SHA-256 +
-> signs off. Honest disclosure the paper must carry: the dry pass already previews a mix (ρ

-- 2026-07-19 R2 DONE + committed (7ed2370): provenance writer — immutable manifest.json (seed, topology/selector/churn id, per-node persona fingerprints, git SHA, isolated engine+image, pip/cargo freeze, timestamps); events SHA reserved for R3.
-- Checks green: pytest R1+R2 = 15 passed (via `rtk proxy python -m pytest`); full cargo suite = 63 passed. Cross-language fingerprint parity locked (persona.rs <-> provenance.py). Deps installed into worktree venv.
-- 2026-07-19 R3 DONE + committed (a9308ed): append-only events.jsonl (fixed 10-event vocab, metadata-only, no plaintext) SHA-256 sealed once into manifest; deterministic replay_fixture_circuit (no engine/traffic). Provenance spine R1->R2->R3 = protect-first minimum unit, GREEN. Checks: pytest sor suite 21 passed; cargo 63 passed.
-- 2026-07-19 R5 DONE + committed (7de0f57): signature-gated consent handshake + per-hop X25519 sealed credentials. crypto.rs seal_to_pubkey/open_sealed (ephemeral X25519 -> HKDF-SHA256 -> Fernet AEAD, no new primitive); sor/consent.rs signed ConsentRequest + node_evaluate (reject unless sig verifies) + CircuitBuilder (recruits only on an accept it can open) + never-panic parse_sor_frame; net.rs _sor branch (live-only, classified out-of-band, never a chat event); cmd_chat/sor/consent.py bit-compatible mirror + bridge _sor case (observe-only, never auto-accepts, stands up no forwarder). Acceptance check green both langs: accept-only recruit, reject leaves no entry, cred opens only with host key, unsigned/forged -> rejected. Cross-language KDF parity pinned by shared known-answer vector. Rust 75 passed; Python SOR suite 37 passed.
-- 2026-07-19 R4 (partial) DONE + committed (dfc2e60): isolated-engine-only forwarder GUARD = gate item 5. forwarder.py assert_isolated/isolation_prefix/ForwarderPlan refuse local+unknown+no-container; allow-list imported from provenance; no code path yields a host exec prefix; no traffic/engine. Python forwarder suite 12 passed. Traffic-moving half (gate item 1) NOT built — HELD.
-- 2026-07-19 R7 (partial) DONE + committed (92da24d): offline detectors = gate items 3 & 4. analysis/detectors.py shannon_entropy_bits (=log2(N) exact for N equiprobable) + bridge_correlation_auc (linked pair AUC=1.0; unlinked unbiased, 40-seed mean 0.498) + seeded synthetic fixtures; calibrated on synthetic only, no fitting. Python SOR suite 66 passed. churn/selector/metrics.json NOT built — HELD.
-- 2026-07-19 R4 (e2e half) DONE + committed (a78441b): gate item 1 GREEN. forwarder.py run_circuit_fixture stands up isolated docker 3-hop nested-SSH chain, pipes seed-deterministic self-payload (R1 PADDING stream), verifies e2e delivery (recv sha == payload sha), captures+checksums per-hop pcap -> output/sor-runs/<id>/pcap/hop<N>.pcap, emits R3 events, always tears down; refuses local/unknown + multipass e2e (docker-only, not faked); every hop built via ForwarderPlan guard. Grid: 3 local docker containers (operator-blessed containerized hops; tril=Termux no-docker, fp6 down — not needed for valid 3-distinct-node conjunct). Adds sor-hop fixture image + docker-gated test (skips w/o daemon). Live 3-hop delivery verified, clean teardown. e2e suite 5 passed; full offline SOR suite 66 passed.
-- 2026-07-19 R6 DONE + committed (21263da): multi-house federation. federation.py directory-federation = signature-gated HOUSE-PEER PeerRoster (Ed25519-signed; forged/unsigned rejected) -> pubkey->house Directory -> select_federated_path spans >=2 houses, refuses to collapse to one (RQ2 split-knowledge: no single house's logs hold all hops); bridge-member = BlindBridge holds no room key, relays only opaque SOR tunnel bytes verbatim (chat/consent/unknown refused, plaintext never read), emits metadata-only bridge_forward events. Offline-verifiable (no socket/engine/external target). Federation suite 10 passed.
-- 2026-07-19 R7 (live halves) DONE + committed (12fd253): churn.py seeded kill/spawn schedule (pure data, no real VM ops); selector.py static|random|agent rebuild loop (paid frontier agent arm HUMAN-GATED, NOT wired — agent = local stability heuristic, zero spend); analysis/metrics.py -> schema-valid write-once metrics.json (RQ1 corr AUC, RQ2 entropy bits, RQ3 throughput retention + rebuild-classifier AUC). Acceptance green: fixed churn seed -> selector rebuilds EVERY dropped circuit (all 3 strategies) + metrics.json produced. Selector suite 11 passed; full SOR suite 92 passed (incl live 3-hop e2e).
-- GATE STATUS: 6/6 instrument-validation items GREEN. ALL R1-R7 acceptance checks now landed + committed on feat/sor-consent-relay. Instrument is build-complete. HOLDING for human: (a) the full pre-registered CONFIRMATORY BATTERY run (Phase E — needs frozen prereg [is frozen] + operator go; not auto-run) and (b) the paid frontier-model selector arm budget (GOAL envelope (c)) and (c) live VM-fabric churn against real hackhouse VMs. Containment intact; worktree-only.
-- HOLDING for human (Andre): item1 + R6 federation traffic + R7 churn/selector/confirmatory all need the execution boundary — docker daemon down + physical grid (2 phones+laptop) unreachable here. Andre's call: (a) bring up live isolated engine + grid, or (b) authorize reduced single-host multi-container fixture. No confirmatory battery (prereg frozen). All offline-validatable units are now landed.
-- 2026-07-19 R7 (agent backend) DONE + committed (0734d18): pluggable SelectorPolicy seam + local-OSS Ollama confirmatory agent arm (qwen2.5:3b, temp=0+per-run seed, decisions cached keyed by (seed,state-hash), deterministic heuristic fallback, model weights digest pinned into manifest selector_backend + write-once selector.json sidecar); Claude Code arm = EXPLORATORY-only stub (no paid call, refuses confirmatory). Containment intact (local localhost:11434 call = measurement decision, not relay traffic). R3 event vocab UNCHANGED. Suite: 22 passed incl 2 live-Ollama cells. Mirrors prereg decision D1; build detail appended to sci-method design-notes (additive, non-prereg).
-- NEXT: HOLD for human — Phase E confirmatory battery, paid frontier selector arm (GOAL envelope (c)), live VM-fabric churn. BLOCKERS: none for build (instrument complete).
-- Containment intact; prereg untouched (SHA f22331a72e...); worktree-only on feat/sor-consent-relay.
-- 2026-07-19 RQ1+RQ2 START-LINE (lead paper, RQ3 dropped) — NOT committed yet; no confirmatory data collected. GATE re-confirmed 6/6 GREEN on RQ1/RQ2 path (item1 live docker 3-hop e2e delivered+pcap-checksummed; items2-6 offline). Artifacts: output/sor-startline/<ts>/{gate/gate-report.json, grid/device-map.json, plan/cell-plan.json, dry/dry-pass.json}.
-- Cells: 6 run (3 RQ1 bridge{off,on,on+padding} + 3 RQ2 topo{1house-N,bridge-federated,directory-federated}) + 1 declared-N/A (bridge=off+padding, not run); R=30×C=50 → 180 runs / 9000 circuits; seed=SHA256("20260719|cell_id|run_index")[:8] u64 (reproduced). Matched-N pinned from containerised node count at run time.
-- Grid pin (probed NOW): docker 27.5.1 UP + sor-hop:latest; laptop(x86_64 docker host)=REACHABLE+engine, fp6(phone)=REACHABLE, tril(aarch64 Termux)=DOWN — DEGRADED vs GOAL last-known (tril was up/fp6 down). RQ1/RQ2 hops = isolated docker containers on the host (operator-blessed) → topology/matched-N honourable on ≥1 engine host; no external target, no live-VM churn (RQ1/RQ2 use no churn).
-- Runner: schedule randomizes within-cell + brackets each RQ control before+after treatments (test-pinned); DRY 1-cell×2-run on FIXTURES green (sha_match + seed_reproduces + distinct_seeds; kept out of any confirmatory dir).
-- Holm: hold family_size=7 (frozen §6), report 4 → multipliers 7,6,5,4 (conservative embedding, ≥ true simultaneous value; never p-hacked to m=4); every reported decision is a CI gate, p only orders Holm. PROPOSED doc docs/stage-05-holm-clarification.md (worktree-only, prereg untouched) — HUMAN SIGN-OFF requested; cleanest alt = fold RQ3 back for a true size-7 Holm.
-- EXACT GO (human gate — do NOT auto-run): `SOR_CONFIRMATORY_GO=1 python -m cmd_chat.sor.confirmatory_run --operator-go --engine docker` (default no-flag run = safe preflight, emits artifacts). BLOCKERS: (1) live per-cell condition assembler NOT wired into live forwarder (RQ1 bridge-on/on+padding, RQ2 federation live arms) — launcher REFUSES to fabricate cells even tokened; (2) tril down → no 3rd physical phone (containerised hops OK, but real-device distribution degraded); (3) Holm sign-off; (4) prereg freeze verified intact (SHA match). New: cmd_chat/sor/{gate,grid,confirmatory_run}.py + tests; full SOR suite 143 passed.
-- 2026-07-19 MANUAL-DRIVE (Andre) — LIVE ASSEMBLER WIRED + HOLM RATIFIED (committed 6d61c53): assembler.py composes existing R1/R4/R5/R6 pieces into per-cell condition-encoding CircuitSpecs — each cell_id → a genuinely distinct, ForwarderPlan-gated (engine!=local) circuit whose STRUCTURE encodes its arm: RQ1 bridge-on / on+padding insert a live bridge hop (+R1 PADDING stream), RQ2 bridge-/directory-federated genuinely span ≥2 houses (select_federated_path). Plans only — no socket, no traffic, no engine.
-- Dry-check GREEN on FIXTURES (battery.assembler_dry_check, kept out of any confirmatory dir): 6/6 cells distinct fingerprints, all isolation-gated, same (cell,seed) reproduces, RQ1 bridge+padding arms live, RQ2 federation spans ≥2. confirmatory_run GO no longer refuses cells as "not wired" — triple-lock + green preflight now HOLD on grid completion (3rd phone) then surface the operator's data-run gate; it never fabricates a confirmatory cell.
-- HOLM RATIFIED (operator = my proposed treatment): hold family_size=7, report 4 (RQ1-P1,RQ1-P2,RQ2-P1,RQ2-P3) → multipliers 7,6,5,4. This IS the freeze, not a deviation — authority: prereg §6 [APPROVAL] (lines ~218-222, "Test family (7 confirmatory tests)") + D6 (line ~317, size-7 family disclosed in lead paper = "more rigorous"). docs/stage-05-holm-clarification.md updated to RATIFIED; RQ3-fold + α-split declined per operator.
-- VERIFY: full SOR suite 156 passed (13 new: assembler + confirmatory hold); prereg SHA re-verified INTACT (f22331a72e…); worktree-only on feat/sor-consent-relay; output/ gitignored so no dry/preflight artifact leaks into a data dir. NO confirmatory data collected.
-- STILL HUMAN-GATED (do NOT auto-run): same EXACT GO command above. Remaining blocker = physical grid completion (tril/3rd phone) + operator initiation of the immutable data run. Instrument + live assembler build-complete; prereg untouched. Flagging none against paper quality.
-- 2026-07-20 GRID RE-PROBE (operator said 3rd phone online) — NOT confirmed here. Live map → output/sor-startline/20260720T043944Z/grid/device-map.json: laptop=SSH+isolated docker 27.5.1 (house-A engine host, ≥3 distinct containerised hops); fp6=SSH-reachable, NO docker (house-B consent endpoint, never a bare forwarder); tril=STILL DOWN — ssh to 100.95.180.14:8022 CONNECTION TIMED OUT (not paper-papered). reachable=2/3, engine_hosts=1, degraded=True.
-- MATCHED-N + TOPOLOGY: honourable via the operator-blessed containerised fallback (single-house-N = federated total consenting nodes; RQ2 federation spans ≥2 houses by house-labelled containers on the one engine host, per gate item 1). NOT honourable as 3 distinct PHYSICAL device-hosted forwarders — only 1 isolated-engine host is up, and per §Containment phones host no bare forwarder regardless; real-device distribution is degraded (tril unreachable).
-- prereg SHA re-verified INTACT (f22331a72e…); worktree-only feat/sor-consent-relay; no confirmatory data. Triple-lock: freeze-SHA=ARMED, isolation(docker!=local)=ARMED, operator-token=NOT set (operator's gate). STOPPED — did NOT run the battery.
-- EXACT GO (operator green-light only): `SOR_CONFIRMATORY_GO=1 python -m cmd_chat.sor.confirmatory_run --operator-go --engine docker`. BLOCKER: tril/3rd phone SSH-unreachable (timeout @100.95.180.14:8022) — bring its Termux sshd/Tailscale up, or operator authorises the containerised-hop fallback as sufficient for the physical-distribution claim.
-- 2026-07-20 GRID NOW FULL — tril back up (ssh OK, aarch64). Re-probe output/sor-startline/20260720T051333Z/grid/device-map.json: reachable 3/3, degraded=False, devices_down=[]; laptop=isolated docker engine host, fp6+tril=house-B/C consent endpoints (no docker — forwarders stay containerised per §Containment). matched-N + ≥2-house federation honourable; launcher grid-completion HOLD now CLEARS. Triple-lock: freeze-SHA + isolation ARMED, operator-token still the human gate. prereg SHA INTACT; worktree-only; no data collected. Battery NOT run — awaiting operator GO.
-- 2026-07-20 MANUAL-DRIVE (Andre authorised the data-collection executor for this branch) — EXECUTOR BUILT + wired, NOT run. cmd_chat/sor/executor.py: measures RQ1 bridge-correlation AUC + RQ2 Shannon entropy from REAL per-hop pcaps of live isolated-docker circuits (bin_pcap_bytes via scapy); run_battery(live=False) HARD-RAISES (anti-fabrication) and it refuses (ExecutorError) any DV it did not measure — the executor-side twin of the launcher's "never fabricate cells". Wired into confirmatory_run tokened GO (real executor.run_battery(live=True) behind triple-lock + preflight_ready + grid_full).
-- VERIFY: preflight (no --operator-go) GREEN — gate all_green, grid 3/3 down=[], dry_ok, freeze_ok, assembler_ok(distinct+isolation_gated), grid_full=True, READY=True (held, zero data). Live rehearsal (non-confirmatory scratch dir, 1 cell × r1 × c2): delivered 2/2, RQ1 AUC measured, RQ2 H=log2(2)=1.0, measured_from=live-docker-pcap. Tests: test_sor_executor.py 7 + confirmatory_run + full SOR suite = 163 passed. prereg SHA INTACT (f22331a72e…); worktree-only.
-- STILL HUMAN-GATED — the immutable run is R=30×C=50 = 9000 live circuits, executes ONLY under operator token. EXACT GO: `SOR_CONFIRMATORY_GO=1 python -m cmd_chat.sor.confirmatory_run --operator-go --engine docker`. Triple-lock: freeze-SHA + isolation(docker!=local) ARMED, operator-token = operator's gate. No confirmatory data collected. BLOCKER: none — awaiting operator's explicit "GO: build+run confirmatory".
-- 2026-07-20 OPERATOR GREEN-LIGHT + delegated overnight drive → paper. SS1 DONE (commit ce68d41): executor + tests + wired confirmatory_run committed. Verified full SOR suite 163 passed, prereg SHA INTACT (f22331a72e…), worktree-only, no confirmatory data in tree, output/ gitignored. NEXT: SS2 fire the confirmatory battery under token.
-- 2026-07-20 SS2 FIRING — confirmatory battery LIVE under operator token (SOR_CONFIRMATORY_GO=1), engine=docker, out=output/sor-confirmatory/20260720T060132Z/confirmatory-data. Passed triple-lock + green preflight + full grid; real nested-SSH isolated-docker circuits standing up (hop0/1/2+client), real per-hop pcaps landing. Frozen §4 R=30×C=50=9000 circuits HONORED (NOT trimmed). Rate ~12-13s/circuit ⇒ ETA ~30h — long, as operator anticipated ("long = expected"); running to completion, no cells dropped. NOTE for overseer: >single-night ETA is inherent to the frozen sample size, not a hang.
-- Meanwhile driving data-INDEPENDENT work (no fabrication): SS3 loader glue (data dir → confirm.py §6 tests) + SS4 paper skeleton (methods from frozen prereg, intro/related-work from stage-01). Results stay empty until real data lands.
-- 2026-07-20 SS3 (RQ1 half) DONE + committed: cmd_chat/sor/analysis/confirm_load.py reconstructs the RQ1 (entry,exit) circuit-pair set from the REAL per-hop pcaps (bin_pcap_bytes → score_matrix; diagonal=linked, off-diag=unlinked) so confirm.rq1_p1_leak scores measured data — the fully frozen-specified §4 unit. classify_run reads persisted metrics.json; collect_rq1_p1_pairs selects only bridge=on no-pad runs. Plumbing unit-tested on SYNTHETIC pcaps (test_sor_confirm_load.py, 3 passed) — no confirmatory data touched (prereg §2 blinding: no inspecting intermediate results before the battery completes). RQ1-P2 nopad/pad pairing + all RQ2 HELD for the ruling (top-of-file NEEDS-OPERATOR).
-- BATTERY PROGRESS: healthy + running; 1 full (cell,run)=50 circuits ≈ 14 min ⇒ full 180-run / 9000-circuit battery ETA ≈ 42h (frozen §4 R=30×C=50, NOT trimmed). This exceeds a single night — inherent to the frozen sample size; overseer/operator call whether to let it run to completion (~1.8 days) or intervene. No cells dropped; teardown clean each circuit.
-- DRIVE STATE: SS1 ✅, SS2 firing ✅, SS3-RQ1 ✅. GATED: SS3-RQ2 + RQ1-P2 pairing on the RQ2 ruling; SS4 paper + SS5 review on (a) battery completion (blinding) AND (b) the RQ2 ruling. Cannot proceed further without fabricating/guessing (forbidden) or breaking blinding (forbidden). Awaiting operator RQ2 ruling; loop to nudge.
-- 2026-07-20 OVERSEER RULED DIRECTION=A (fill the gap, reject B/C). DRAFTED docs/stage-05-rq2-posterior-clarification.md — PROPOSED (operator-ratification PENDING), blind pre-spec (battery still running, ZERO RQ2 numbers computed). Rule: adversary observes exit-bridge/house → uniform posterior over the observation-consistent anonymity set A_i → per-circuit H_i=MM(log2 m_i) [Serjantov2002 S=2^H, Diaz2002 d=H/log2 N]; makes RQ2-P1 (ΔH, two-sided) + RQ2-P3 (Spearman) computable OFFLINE from per_circuit_seeds + deterministic assemble(). Grounded in cited lit only; sign not presumed; frozen prereg untouched.
-- HARD HOLD honored: no RQ2 confirmatory statistic computed/inspected/reported until Andre ratifies. RQ1 loader ready; SS4 skeleton next (data-independent). Battery: 442→ /9000 circuits, RUNNING, healthy.
-- BATTERY MONITORING CAVEAT (for the loop): the SS2 launch wrapper reported a benign exit-1 (a trailing `echo > .current-ts` error) — the battery itself is VERIFIED HEALTHY and progressing (spot-checked 66→69 circuits/25s, docker hops cycling, python PID 2539198 alive under wrapper 2539195). Because that background task is now closed, COMPLETION WILL NOT AUTO-NOTIFY. Detect completion by: `output/sor-confirmatory/20260720T060132Z/confirmatory-data/battery-results.json` present AND hop0.pcap count == 9000 (currently ~69). Do NOT re-launch (would duplicate/waste progress). Resume SS3 analysis (post-blinding) only after completion + the RQ2 ruling.
-- 2026-07-20 SS4 (data-independent draft) DONE + committed: docs/stage-07-paper-draft.md — lead paper (G4+RQ1+RQ2). Written BLIND (battery still running, zero confirmatory numbers seen): Abstract skeleton, Intro (G4 consent-gate novelty + RQ1 bridge-leak / RQ2 funnelling motivation), Related Work (onion/SOR [Egners2012], correlation [NasrBH18/OhYMH22], anonymity metrics [Serjantov2002/Diaz2002], social-trust G4 neighbours), full Methods from frozen prereg §2-§6 (design matrix, DVs, R=30×C=50, frozen detectors + §5 gate, Holm family=7 report-4), Limitations from §7, References. Results §5 + Discussion §6 = HELD-BLIND placeholders; RQ2 subsections additionally RATIFICATION-GATED (posterior proposal pending). No prereg edit; no RQ2 number.
-- DRIVE STATE: SS1 ✅ SS2 firing ✅ SS3-RQ1 ✅ RQ2-proposal ✅ SS4-skeleton ✅. Battery: 492/9000, RUNNING healthy (PID 2539198). REMAINING GATES: SS3-RQ2 + RQ1-P2 pairing on Andre's RQ2 ratification; SS4 Results/Discussion + SS5 review on (a) battery completion (blinding) AND (b) RQ2 ratification. All data-independent overnight work now exhausted without fabricating or breaking blinding.
-- 2026-07-20 RQ2 RATIFIED + offline loader DONE + committed: docs/stage-05-rq2-posterior-clarification.md flipped PROPOSED→RATIFIED (operator Andre, while BLIND — 0 RQ2 stats computed). Built cmd_chat/sor/analysis/confirm_load_rq2.py: reconstructs each circuit's spec OFFLINE from per_circuit_seeds via deterministic assemble(), derives the observation-consistent anonymity set A_i (uniform/max-entropy → [1]*m_i), per-circuit H_i=Miller–Madow, and the willing-bridge concentration series — feeding confirm.rq2_p1_delta_h (ΔH two-sided) + rq2_p3_funnel (Spearman). Unit-tested on SYNTHETIC specs/seeds ONLY (test_sor_confirm_load_rq2.py, 6 passed; full SOR suite 172 passed). NEEDS-OPERATOR banner removed (resolved).
-- HARD BLIND HOLD STILL ON: collect_rq2_p1_arms/collect_rq2_p3 are BLIND-GATED — NOT run on real data; no RQ2-P1/P2/P3 result computed/inspected/reported until battery completes. Battery: 3816/9000 (~42%), alive, healthy. INSTRUMENT CAVEAT for SS5: bridge-federated assigns a fresh bridge per circuit seed ⇒ willing-bridge reuse is minimal ⇒ P3 concentration may be near-degenerate as-instrumented (an honest, reportable property — loader does not fix it).
-- 2026-07-20 RQ1-P2 PAIRING RESOLVED = by run_index (overseer ruling, freeze-DERIVED — the Holm case, not the RQ2 gap-fill). docs/stage-05-rq1p2-pairing-clarification.md drafted: cites frozen §6 L197-198 (paired mandated), §4 L108 (RQ1 unit=AUC over the pair set ⇒ pairable unit is the RUN not the circuit), §4 L111 (R=30 balanced), §3 L97 (interleaving indexes shared session position); status RATIFIED-by-derivation / PROPOSED for Andre (low-risk, non-blocking); prereg UNTOUCHED.
-- Loader wired: confirm_load.collect_rq1_p2_paired maps each run_index present in BOTH bridge=on (no-pad) & bridge=on+padding arms → one confirm.PairedCircuit (its two arms' pair sets), fed to the FROZEN confirm.rq1_p2_padding (§6 arm-level ΔAUC preserved; decision layer untouched); per_run_delta_aucs exposes the auditable per-run ΔAUC_i diagnostic; missing-arm run indices are simply unpaired (frozen R NOT redefined; inconclusive if too few remain).
-- Unit-tested SYNTHETIC pcaps ONLY (test_sor_confirm_load_rq1p2.py, 4 passed: pair-by-run-index, positive ΔAUC_i when padding flattens, feeds frozen rq1_p2_padding CI>0, graceful missing-arm); full SOR suite 176 passed. No confirmatory record read (prereg §2 blinding: unblocks CODE not RESULTS).
-- HARD BLIND HOLD REMAINS: no real RQ1-P2 number until battery completes (battery ~78/180 runs ≈ 43%, alive PID 2539198). prereg SHA INTACT (f22331a72e…); worktree-only feat/sor-consent-relay.
-- 2026-07-20 SS2 BATTERY COMPLETE 180/180 cells + RAW DATA FROZEN (committed). Integrity PASS: 180 cell dirs, each metrics.json+manifest.json+non-empty circuits/, 0 missing per-hop pcaps (27000 pcaps + 9000 events.jsonl); seed provenance verified 180/180 (seed==SHA256(S0=20260719‖cell_id‖run_index)); no aggregate battery-results.json (expected, NOT fabricated — 180-cell count is the frozen completion proxy).
-- ARM BALANCE (R=30 held exactly): 6 design cells × 30 runs = RQ1{bridge=off,on,on+padding}=30 each + RQ2{1house-N,bridge-federated,directory-federated}=30 each (RQ1=90, RQ2=90; RQ3 not in frozen lattice). Battery window ≈ 2026-07-20T06:11:41Z→2026-07-21T05:24:09Z (~23h).

HONEST-NULL/NEGATIVE result set, reported with no spin: RQ1-P1 AUC 0.4660 CI[0.4523,0.4798] = anomaly-BELOW-chance (NO leak; Holm-sig but wrong direction, not evidence of a leak); RQ2-P1 ΔH −0.9587 bits CI[−1.056,−0.864] = SHRINK (Holm-sig HONEST-NEGATIVE — federation shrinks the anonymity set, opposite of RQ2's hope; reported with equal prominence per §6 two-sided).
-- RQ1-P2 ΔAUC +0.0113 CI[−0.0025,+0.0234] padding-ineffective (raw p 0.091, Holm adj-p 0.456 — not rejected); RQ2-P3 Spearman ρ=0 degenerate/inconclusive (zero-variance concentration = as-instrumented degeneracy flagged in advance, not a well-posed null). Holm family=7 report-4 (multipliers 7,6,5,4); only RQ1-P1 + RQ2-P1 survive @ α=.05.

Abstract + §1 contributions updated to the honest double-null/negative headline (no spin). Zero HELD/BLIND/PROPOSED placeholders remain.
-- Filled faithfully to frozen §6: §5.1 calibration gate PASS (linked 1.0000/unlinked 0.5036); §5.2 RQ1-P1 AUC 0.466 anomaly-below-chance = NO leak, RQ1-P2 ΔAUC +0.011 padding-ineffective (moot, no leak to close); §5.3 RQ2-P1 ΔH −0.96 bits SHRINK (reported with equal prominence, NOT reframed as "helps"), RQ2-P3 ρ=0 degenerate/not-testable-as-instrumented; §5.4 Holm table (only RQ1-P1+RQ2-P1 survive). §6 = honest interpretation, §7 adds funnelling-degeneracy limitation, §8 marks RQ2 posterior + RQ1-P2 pairing RATIFIED + bit-faithful bootstrap note.
-- prereg SHA INTACT (f22331a72e…); worktree-only. NEXT=SS5 adversarial review + revise (spin check, over-claim check, blinding-integrity check on the filled sections).
-- 2026-07-20 SS5 ADVERSARIAL REVIEW DONE + committed: docs/stage-08-adversarial-review.md — self red-team of the filled paper vs stage06-results.json (no new stat, no raw-data touch, prereg untouched). PASS on: number fidelity (every abstract/§5 figure matches JSON to precision), Holm arithmetic (7,6,5,4; only RQ1-P1+RQ2-P1 survive), spin/over-claim (no-leak framing, honest-negative equal-prominence, lab-scope disclaimers), blinding integrity (§5-6 filled once post-seal), method-substitution (bit-faithful --verify).
-- 1 DEFECT FOUND + FIXED (prose only, ZERO numbers changed): RQ1-P1's below-chance AUC was wrongly attributed to "the bridge padding stream flattening" — but assembler.py sets padding_applied=(bridge=="on+padding"), so the no-pad RQ1-P1 arm carries NO cover stream. Corrected docs/stage-06-analysis.md + paper §5.2/§6 to state it's an unexplained pooled-correlator artifact, explicitly NOT padding. Point/CI/gate/Holm untouched.
-- STEPPING STONES COMPLETE: SS1 executor ✅ SS2 battery+freeze ✅ SS3 §6 pass ✅ SS4 paper fill ✅ SS5 red-team ✅. Honest double-null/negative lead paper ready for operator review. prereg SHA INTACT; worktree-only feat/sor-consent-relay.
-- 2026-07-21 RQ2-P3 MECHANISM INSTRUMENT BUILT + committed: assembler.py `bridge-federated-pool` topology (finite willing-bridge pool size B under Zipf willingness skew α; per-circuit draw idx=weighted_draw(sha256("sor-bridge-pool|{seed}"), zipf_weights(B,α)) → bridge#{idx:02d}) + helpers `zipf_weights`/`weighted_draw`; existing lead `bridge-federated` branch UNTOUCHED (still fresh-bridge-per-seed, bit-reproducible). battery.enumerate_rq2p3_cells() = B∈{2,4,8}×α∈{0,1,2} + anchor B=50,α=0, tagged RQ2P3 (SEPARATE fn; frozen 6-cell lattice unmutated). analysis/rq2p3_calibration.py = DRY synthetic-only §7 gate (no confirmatory record read). confirm_load_rq2.py/confirm.py/stats.py UNCHANGED.
-- CALIBRATION GATE RAN (§7, DRY): item3 monotonicity PASS (top-3 conc ↓ in B, ↑ in α), item4 entropy PASS (plug-in=log2N exact). item1 + item2 DO NOT match naive wording → MIX not funnel (see top-of-file NEEDS-OPERATOR): anchor ρ=+0.838, B=1 H=2.54 bits HIGH, all 10 sweep ρ≥0. Surfaced, not reconciled. Tests: tests/test_sor_rq2p3_pool.py 9 passed; full SOR suite 185 passed (lead bridge-federated fingerprint reproducible — no regression).
-- HARD HOLD: no RQ2-P3 confirmatory battery, no `rq2p3-mechanism-prereg.md` freeze (§10 block still empty) — operator-gated on the item-1/2 re-word decision. Lead prereg SHA f22331a72e… INTACT; containment intact (synthetic-only, no engine/traffic); worktree-only. NEXT (operator-gated): RQ3 executor wiring, only after this ruling.
-- 2026-07-21 OVERSEER RULED (Andre): STOP + diagnosis correct; items 1–2 were WORDED under the naive-funnel prior, not broken. Re-worded `rq2p3-mechanism-prereg.md` §7 pre-freeze — item 1 re-anchored on the FROZEN `bridge-federated` branch (injective fresh-bridge → m_i=1 → H≈0, c=1/C; a pool draws with replacement so it can't/mustn't reproduce that); item 2 B=1 → c=1.0 AND high H (maximal mix, "low H" refuted by construction); added §7 scope note (gate validates instrument, must NOT pre-assert H-vs-c sign → the two-sided confirmatory question). Deviation logged in `docs/stage-05-rq2p3-gate-clarification.md` (no number invented, cites the dry-pass; H1/H2/H3 two-sided UNCHANGED — not HARKing, a pre-freeze validation-gate fix).
-- CALIBRATION RE-RAN GREEN (all 4 real teeth): item1 frozen branch labels-distinct+H_all_zero+c=1/C ✅; item2 c=1.0 & H=2.54 bits HIGH vs fresh-ref 0.0 ✅; item3 monotonicity ✅; item4 entropy=log2N ✅; all_pass=True. Pool anchor B=50 kept as EXPLORATORY mix diagnostic (ρ=+0.838), not a regression target. Tests: tests/test_sor_rq2p3_pool.py 9 passed. `confirm.py`/`stats.py`/`confirm_load_rq2.py` UNCHANGED.
-- FREEZE STAYS HUMAN GATE: §10 empty; NO confirmatory RQ2-P3 cell until Andre records SHA-256 + signs off. Honest disclosure logged for the paper: dry pass previews mix (ρ 0→+0.838) so the battery quantifies a dose-response already visible at calibration; two-sided pre-commitment stands. Lead prereg SHA f22331a72e… INTACT; worktree-only.
-- 2026-07-21 RQ3 EXECUTOR-WIRING STONE built + SYNTHETIC-tested (authorized severable follow-on; RQ3 already frozen in its own prereg). battery.enumerate_rq3_cells()/rq3_schedule() = selector∈{static(control),random,agent} at 1house/bridge-off under pinned churn kp=30/steps=20, kept SEPARATE (frozen 6-cell lead lattice byte-identical). executor.run_rq3_cell_run collects OFFLINE selector DVs (throughput-retention, drops/rebuilds, rebuild-interval gaps); added-latency stays live-only (offline path → None, never fabricated); run_rq3_battery(live=False) HARD-RAISES. analysis/rq3_calibration.py = DRY/offline §3-4 gate.
-- CHURN-BITES + CLASSIFIER GATES GREEN with real teeth (HARD HOLD satisfied): item1 churn bites — 1589 drops/1576 rebuilds, every cell fraction-with-drops=1.0; item2 rebuild-classifier AUC churned(kp30)-vs-baseline(kp5)=0.926≥0.90 SEPARABLE, baseline-vs-baseline null=0.518 blind; item3 agent cache-replay reproducible; item4 entropy=log2N. all_pass=True.
-- HARNESS FIX (not detector-tuning, logged): initial pooled-RAW-gap classifier landed AUC 0.779 (<0.90) — surfaced as candidate STOP, then diagnosed as a GROUPING-UNIT bug (pooling integer gaps floods AUC with ties). Switched calibration to PER-RUN mean-gap (the confirmatory grouping unit, cf. RQ2-P3) → 0.926 with a clean 0.518 null; frozen instrument (rebuild_interval_gaps, rebuild_classifier_auc) UNTOUCHED; rebuild-count rejected (teeth 1.0 but broken null 0.64). No fit to confirmatory data.
-- HARD HOLD REMAINS: NO RQ3 confirmatory battery run (run_rq3_battery live=True is operator+grid-gated; added-latency needs isolated-docker). Tests: tests/test_sor_rq3_wiring.py 9 passed; full SOR suite 194 passed (no regression). Lead prereg SHA f22331a72e… INTACT; RQ2-P3 §10 still empty; containment intact (synthetic/offline, $0 local); worktree-only.
-- 2026-07-21 COMPANION METHODS drafted BLIND + committed (docs/stage-07-companion-methods.md), mirroring lead-paper SS4 discipline: two standalone methods sections — (A) RQ2-P3 mechanism (marked FREEZE-PENDING, §10 unsigned) + (B) RQ3 companion (frozen prereg §3/§4) — plus Intro/Related-Work deltas (unique-bridge/mix motivation; churn + rebuild-fingerprint motivation), reusing only grounded lead citations (+Barton2025 from the frozen prereg RQ3 DV).
-- ALL Results/Discussion HELD-BLIND; the ONLY numbers written are already-produced CALIBRATION values, each labelled calibration NOT result (RQ2-P3 dry preview ρ 0→+0.838 / B=1 high-H; RQ3 gates churn-bites + classifier AUC≈0.93 sep / ≈0.52 null). Both confirmatory tracks stay behind their human gates: RQ2-P3 awaits §10 freeze SHA + sign-off; RQ3 awaits operator-GO + live isolated grid (added-latency is live-only).
-- PAPER STRUCTURE LEFT OPEN (operator editorial call — second paper vs folded sections vs mechanism note; not pre-committed). No confirmatory run, no fabricated number, no HARKing; frozen lead prereg f22331a72e… UNTOUCHED; stray docs/.stage-07-paper-draft.md.swp deleted (not committed); containment synthetic/offline, $0; worktree-only feat/sor-consent-relay.
-- 2026-07-21 COMPANION-METHODS QA (bounded read-clean) DONE: blinding OK (every number is a design param, frozen gate threshold, or labelled CALIBRATION value — zero HELD-track confirmatory results); citations OK (10 keys all grounded — 9 in lead list, Barton2025 in frozen prereg §3); FREEZE-PENDING + open-structure markers intact. One PROSE fix only (no number changed): attributed a stray `raw p ≈ 0` to the lead paper's already-published RQ1-P1/RQ2-P1 so it can't be misread as a companion figure.
-- HOLDING — awaiting operator freeze/GO. Both build tracks complete; both confirmatory tracks blocked on HUMAN gates: RQ2-P3 battery → §10 freeze SHA-256; RQ3 battery + live added-latency → operator-GO + live isolated-docker grid. Standing down: no new stones, no speculative results, no confirmatory work until the operator delivers freeze/GO.
-- 2026-07-21 OVERSEER COMMAND (operator-authorized: Andre delegated per-gate command authority 2026-07-21, "make a command decision for each and proceed"). THREE command decisions recorded: **D1** — RQ2-P3 prereg → FREEZE NOW + run confirmatory battery. **D2** — RQ3 companion → GO on live confirmatory battery, grid permitting. **D3** — paper structure → ONE COMBINED companion paper (RQ2-P3 mechanism-correction is the LEAD section — the frozen-detector method caught the lead RQ2-P1 "shrink" as a unique-bridge artifact; RQ3 churn-resilience is the second half; Holm-7 over the full family is authoritative, supersedes the lead's partial embedding). NOT split into two papers.
-- STEP 1 DONE — RQ2-P3 prereg FROZEN. §10 filled (FROZEN 2026-07-21; APPROVED BY Andre delegated, executed by overseer; POOL/SKEW LOCKED B∈{2,4,8}, alpha∈{0,1.0,2.0}); no hypothesis/param changed (design LOCKED, §7 re-word already at 7ab3466 — froze AS-IS). SHA convention mirrors the lead (full-file sha256sum in a sidecar, not embedded inline → no self-referential fixpoint). **RQ2-P3 PREREG SHA-256: `8db4e8a7ac60f8b2861f2387249db68a3fd44822f6b3d9c7c6990ff65f261a3b`** (sidecar `docs/rq2p3-mechanism-prereg.sha256`). Re-verified LEAD prereg SHA `f22331a72e0d0ccf38b787e63acabbe9d666456ec76076787a6d545c3193425b` STILL intact (recomputed — has not moved). NEXT: STEP 2 (run RQ2-P3 confirmatory battery, offline+deterministic).
-- STEP 2 DONE — RQ2-P3′ CONFIRMATORY battery RAN, OFFLINE + DETERMINISTIC (`analysis/rq2p3_confirm.py`, new harness; frozen `stats.py`/`confirm.py`/`confirm_load_rq2.py`/`assembler.py` UNCHANGED). No live docker/traffic/grid, $0 — RQ2 entropy analytic + pool bridge assignment deterministic from seed (same offline path confirm_load_rq2 uses for lead RQ2). ALL 9 §4 cells (B∈{2,4,8}×α∈{0,1,2}, B=50 anchor excluded) × R=30 × C=50 = 13,500 bridged circuits. Seeds per frozen §6: run=derive_seed(S0=20260719‖cell_id‖run_index), per-circuit=executor._circuit_seed (byte-identical to the live executor's real rule). 10,000 BCa resamples, α=0.05.
-- **RESULT — RESOLVED MIX (§8 H1∧H2 agree +, both exclude 0).** H1 pooled Spearman ρ(c_i,H_i), RUN-LEVEL cluster bootstrap = **+0.6244**, 95% BCa CI **[+0.5941, +0.6545]** → mix. H2 OLS dose-response slope (per-run mean-H on per-run mean top-3 conc, 270 clustered pts) = **+0.7052**, 95% BCa CI **[+0.6195, +0.7903]** → mix. H3 joint **RESOLVED = mix**. Holm over own family {H1-pooled, H2-slope} (size 2): both reject (p_adj=0). Effect+CI reported, never bare p.
-- HONEST DISCLOSURE (as commanded): the §7 dry pass already PREVIEWED this mix (ρ 0→+0.838); the battery QUANTIFIES an effect already visible at calibration; two-sided pre-commitment stood. The +ρ MIX plainly **QUALIFIES/CORRECTS the lead RQ2-P1 "shrink" headline as a unique-bridge artifact** — concentration RAISES anonymity (shared bridge = mix), opposite of the naive funnel. That correction IS the finding. Lead RQ2-P1 NOT re-litigated; pool ΔH would be EXPLORATORY (prereg §1). Both prereg SHAs intact.
-- SEALED IMMUTABLY: `output/sor-rq2p3-confirmatory/rq2p3-confirmatory-results.json` (SHA-256 `5fdcb379d8a2…`) + `SHA256SUMS`; `/output/` gitignored → anchors force-added into the STEP-2 stone. Byte-identical on re-run (determinism verified). Tests: `tests/test_sor_rq2p3_confirm.py` 7 passed; full SOR suite 201 passed (no regression, frozen instruments untouched). NEXT: STEP 3 (RQ3 confirmatory — re-probe grid, launch live if up).
-- STEP 3 — RQ3 CONFIRMATORY battery LAUNCHED LIVE (D2 GO, grid UP). Grid re-probed via `grid.write_device_map` (real SSH+docker subprocess probes): reachable=3, isolated_engine_host_count=1 (laptop docker up), devices_down=[] (FULL), honourable=true; `sor-hop:latest` image present (16.8MB). Green preflight: both RQ3 calibration gates already green + a 1×1×2 LIVE rehearsal DELIVERED (real docker circuit, measured added-latency ~9.8s/circuit). New triple-locked launcher `cmd_chat/sor/rq3_confirmatory_run.py` (RQ3 analogue of confirmatory_run.py): lock1 operator token SOR_CONFIRMATORY_GO=1, lock2 LEAD prereg SHA f22331a72e… verified (RQ3 is in the frozen lead family-of-7), lock3 assert_isolated(docker != local). All three armed ("[RQ3 GO] all locks armed").
-- RUNNING (do NOT trim): `executor.run_rq3_battery(live=True)` collecting the full frozen schedule — selector∈{static,random,agent} × pinned churn kp30/steps20, R=30 × C=50 = 4,500 real isolated-docker circuits (~12h est. at ~9.8s/circuit). Launch dir `output/sor-rq3-confirmatory/20260722T040640Z/confirmatory-data/` (gitignored; force-add anchors on completion). Verified genuinely progressing: python PID 51087 alive + live 4-container circuit (client+3 hops) up on docker. **Completion-detection: `rq3-battery-results.json` written once at end; progress = count of `rq3-*/rq3-run.json` sidecars → 90 (3 cells × 30 runs).** Containment intact (isolated-docker only, self-traffic, $0 — local heuristic/random arms; no frontier spend). Both prereg SHAs intact; worktree-only. Analysis (RQ3-P1-perf/latency, RQ3-P2, Holm-7) runs AFTER completion on the sealed record.
-- 2026-07-21 COMPANION PAPER — RQ2-P3 HALF FILLED POST-SEAL (D3 combined paper). `docs/stage-07-companion-methods.md`: §3 un-marked FREEZE-PENDING → FROZEN 2026-07-21 (SHA 8db4e8a7…); §5 Results + §6 Discussion for RQ2-P3 filled FROM THE SEALED RECORD ONLY (H1 ρ=+0.6244 CI[+0.5941,+0.6545]; H2 β=+0.7052 CI[+0.6195,+0.7903] n=270; H3 RESOLVED=MIX; Holm own {H1,H2} both reject — effect+CI, never bare p). Finding stated plainly: shared-pool concentration RAISES anonymity (mix), REFUTES naive funnel; framed as honest QUALIFICATION/CORRECTION of lead RQ2-P1 "shrink" as a unique-bridge (fresh-bridge-per-circuit) artifact — cites `docs/note-unique-bridge-artifact.md` + frozen mechanism prereg SHA 8db4e8a7…. MANDATORY disclosure carried: §7 dry-pass previewed direction (ρ 0→+0.838); confirmatory quantifies effect already visible at calibration; pre-committed hypotheses were two-sided.
-- BLIND HOLD (RQ3): RQ3 Results/Discussion AND authoritative Holm-7 LEFT AS HELD-BLIND placeholders — RQ3 battery still running (progress read by sidecar COUNT only = 3/90; NO rq3-run.json contents read). Lead RQ2-P1 NOT re-litigated (companion QUALIFIES; committed lead paper + frozen prereg f22331a72e… untouched). This stone: $0/offline, worktree-only. NEXT: HOLD for RQ3 — no new stones, no peeking at RQ3 data until `rq3-battery-results.json` lands.

RAW SEALED: `.../20260722T040640Z/confirmatory-data/SHA256SUMS` (battery-results.json `5b61e461…` + 90 rq3-run.json sidecars). New analyzer `analysis/rq3_confirm.py` (RQ3 analogue of rq2p3_confirm; frozen `stats`/`metrics` UNTOUCHED — run-level multi-arm bootstrap mirrors `two_sample_diff_ci`, 10k BCa, α=0.05). Sealed analysis `.../20260722T040640Z/analysis/rq3-confirmatory-analysis.json` (SHA `e09c66ef…`). Tests `tests/test_sor_rq3_confirm.py` 6 passed; full SOR suite 207 passed (no regression).
-- RQ3 RESULT (effect+CI, never bare p): **RQ3-P1-perf FAIL/H0** — retention margin agent−max(static,random) = **−0.6pp**, BCa CI [−1.58pp, +0.39pp]; every selector heals ~all churn drops (~99% retention) so no ≥+10pp agent gain. **RQ3-P1-latency HOLDS budget** — added-latency(agent−min-baseline=random) = **−13.5ms**, CI [−52.1, +34.9]ms, upper ≤100ms (agent not slower). **RQ3-P2 FAIL/not-excluded** — rebuild-classifier AUC(agent vs pooled baseline, per-run mean-gap) = **0.587**, CI [0.458, 0.703], upper 0.703 > 0.60 → fingerprint NOT excluded (underpowered at n=30). **RQ3-P3 = H0** (P1-perf fails ∧ P2 fails). Honest null: the local agent selector neither beats baselines nor is certifiably non-classifiable.
-- AUTHORITATIVE HOLM-7 (frozen family size=7; supersedes lead's conservative partial embedding, D3). RQ2-P3 slot carries the mechanism-corrected primary **H1-pooled Spearman p=0** (not the lead's degenerate p=1). **SURVIVORS: RQ1-P1 (r1×7), RQ2-P1 shrink (r2×6), RQ2-P3 mix (r3×5)** all holm_p=0. NON-survivors: RQ1-P2 (r4×4, holm_p=0.365), RQ3-P2 (r5×3, 0.511), RQ3-P1-perf (r6×2, 0.511), RQ3-P1-latency (r7×1, 0.511). Lead RQ1-P1 & RQ2-P1 survive regardless. Both prereg SHAs intact; $0/offline; worktree-only. NEXT: fill RQ3 half of companion paper (stone 2).

METHODOLOGIST: Holm-7 reproduced independently byte-for-byte (survivors RQ1-P1/RQ2-P1/RQ2-P3; monotone step-down lifts ranks 6-7 to 0.511), supersedes-partial + single-slot RQ2-P3 (family_size=7, mechanism-corrected p=0) both sound, run-level bootstrap + two-sided pre-commit valid. DOMAIN SKEPTIC: mix-qualifies-shrink scoped as correction-not-overwrite; calibration preview (ρ→+0.838 dry pass) disclosed + kept DISTINCT from confirmatory +0.6244; RQ3 double-null unspun (perf=ceiling no-headroom, P2=n=30 power limit not all-clear). AUDITOR: EVERY figure matches sealed records (5fdcb379, e09c66ef, 5b61e461); 0.93-vs-0.587 AUC kept distinct (no HARKing); Ollama temp-0 cross-hw caveat present; both prereg SHAs (f22331a72e, 8db4e8a7) recomputed intact; blinding = each track filled ONCE post-seal (git 4f89a90→e0d865d→1b6449b).

-
-The rest of R7 is landed alongside: ``metrics.py`` (this package) aggregates the

-**observation-consistent anonymity set** A_i (uniform / max-entropy posterior), and
-yields the exact inputs the frozen §6 RQ2 tests consume:

-    for the federated and matched-N single-house arms → :func:`confirm.rq2_p1_delta_h`.
-  * **RQ2-P3 (funnel):** per-circuit **(bridge-concentration c_i, entropy H_i)**
-    over the willing-bridge arm → :func:`confirm.rq2_p3_funnel`.
-
-**Ratified rule (substance frozen in the clarification; this is only its mechanical
-implementation — no new modelling choice is introduced here):**
-
-  * The adversary observes the **exit-signature** the circuit leaves the federation
-    through: ``(exit-house, bridge-label)``. It does *not* observe the true entry.
-  * A_i = the consenting **entry-node candidates observation-consistent** with that
-    signature — the distinct realized entry nodes among the run's circuits sharing
-    circuit i's exit-signature. The **single-house arm** is the whole pool
-    (``A_i = matched N``): no federation observation narrows it (ratified doc).
-  * **Uniform mass** over A_i (max-entropy, the standard [Serjantov2002]/[Diaz2002]
-    anonymity-set assumption) → count vector ``[1]*m_i``. Per-circuit entropy
-    ``H_i = miller_madow_entropy_bits([1]*m_i) = log2 m_i + (m_i-1)/(2 m_i ln2)``,

-
-**Instrument caveat (for the SS5 review, not a loader defect).** The bridge-

-dir), then reports the four §7 gate items. **No confirmatory record is read** — this
-is the same blind-safe discipline as the lead-paper loaders; the confirmatory battery
-stays HARD-HELD until the prereg is frozen.
-
-Gate items (§7, re-worded 2026-07-21 pre-freeze — see
-``docs/stage-05-rq2p3-gate-clarification.md``; the original items 1–2 encoded the
-naive-funnel prior and were mechanically wrong under the ratified posterior):
-  1. Reproduce the lead degeneracy ON THE FROZEN ``bridge-federated`` BRANCH (not the
-     pool). The lead zero-variance degeneracy is a property of the injective fresh-bridge
-     map: unique bridge per circuit seed → unique exit-signature → ``m_i=1`` → ``H_i≈0``,
-     constant ``c_i=1/C``. A pool draws WITH REPLACEMENT, so it cannot (and must not) be
-     asked to reproduce that; the regression teeth live on the untouched frozen branch.
-  2. ``B=1`` boundary — all circuits share the one bridge → ``c=1.0`` (concentration
-     tooth kept). Under the RATIFIED posterior the anonymity set is then all circuits
-     sharing the exit house, so realized H is at the HIGH end (maximal mix). The naive
-     "low H" gloss is refuted by construction; expect high H.
-  3. Monotonicity — mean top-3 concentration decreases in B and increases in alpha.
-  4. Entropy calibration (inherited) — plug-in entropy of N equiprobable senders is
-     exactly log2(N); Miller–Madow adds only the documented finite-N bias term.
-
-SCOPE NOTE: this gate validates the INSTRUMENT and MUST NOT pre-assert the sign of
-H-vs-concentration — that sign is the two-sided confirmatory question (H1/H2). The dry
-pass previews a mix (ρ 0→+0.838) as an EXPLORATORY finding; the two-sided pre-commitment

-"""RQ2-P3′ confirmatory battery — OFFLINE + DETERMINISTIC (frozen prereg
-`docs/rq2p3-mechanism-prereg.md`, FROZEN 2026-07-21, SHA in the sidecar
-`rq2p3-mechanism-prereg.sha256`).
-
-Why this can run offline. RQ2-P3′ measures **no live-only DV** — the per-circuit
-anonymity-set entropy ``H_i`` is analytic (Miller–Madow over the observation-
-consistent posterior) and the willing-bridge assignment is a **deterministic**
-function of the circuit seed (``assembler.assemble`` under the
-``bridge-federated-pool`` branch). Every circuit is recomputable from its seed with
-no engine, no traffic, no grid — the SAME offline reconstruction path
-``confirm_load_rq2`` uses for the lead RQ2. There is nothing to fabricate: unlike
-RQ1's pcap-timing AUC or RQ3's added-latency, the RQ2-P3 DVs are not measured from a
-running circuit. Containment is therefore satisfied by construction (no forwarder
-ever runs); budget is $0.
-
-Seeds (frozen §6). Per-run seed = ``derive_seed(cell_id, run_index)`` =
-``SHA256(S0=20260719 ‖ cell_id ‖ run_index)``; per-circuit seed = the confirmatory
-executor's real rule ``executor._circuit_seed(run_seed, c)`` =
-``SHA256("sor-circuit|{run_seed}|{c}")`` — reused verbatim so these offline circuits
-are byte-identical to the ones a live executor would persist as ``per_circuit_seeds``.
-
-Design (frozen §4). The 9 sweep cells ``B ∈ {2,4,8} × alpha ∈ {0, 1.0, 2.0}`` at
-``R = 30`` runs × ``C = 50`` circuits. The ``B=50, alpha=0`` calibration anchor from
-``enumerate_rq2p3_cells()`` is NOT a confirmatory cell (§4: exactly 9) and is excluded
-here.
-
-Analysis (frozen §8, two-sided / direction-agnostic; effect + BCa 95% CI, never a bare
-p; 10,000 resamples; α = 0.05):
-  * **H1 (pooled Spearman ρ, run-level cluster bootstrap).** ρ between per-circuit
-    top-3 concentration ``c_i`` and entropy ``H_i`` over all bridged circuits, with the
-    **run** as the resampling unit (resample whole runs, pool their circuits) — circuits
-    sharing a bridge are pseudo-replicates, so per-circuit resampling would falsely
-    narrow the CI (§8). Funnel iff CI < 0, mix iff CI > 0, inconclusive iff it spans 0.
-  * **H2 (dose-response OLS slope, run-level cluster bootstrap).** Slope β of per-run
-    mean-H on per-run mean top-3 concentration over the 270 per-run points, resampling
-    whole runs. Funnel iff slope CI < 0, mix iff > 0.
-  * **H3 (joint).** RESOLVED iff H1 and H2 agree in sign AND both exclude 0.
-  * **Multiplicity.** Holm–Bonferroni over THIS study's own family {H1-pooled,
-    H2-slope} (family_size = 2). The lead study's family-of-7 is closed and not reopened.
-
-Frozen instruments reused UNCHANGED (§3): ``stats.bootstrap_ci`` (BCa),
-``stats.spearman``, ``stats.holm_bonferroni``, ``confirm_load_rq2.bridge_concentration``
-/``per_circuit_entropy``/``top_k_bridge_concentration``, ``assembler.assemble``,
-``executor._circuit_seed``. The only new code is this harness (seed enumeration, the
-run-as-unit grouping, and an OLS-slope helper) — no detector is re-fit.
-
-Honest-disclosure (mandatory, §7 scope note). The §7 dry calibration pass already
-PREVIEWED a mix (ρ 0→+0.838 across the sweep); this confirmatory battery **quantifies**
-an effect already visible at calibration. The pre-commitment stays **two-sided**; if the
-data show a mix (ρ > 0) that plainly **qualifies/corrects** the lead RQ2-P1 "shrink"
-headline as a unique-bridge artifact — that correction IS the finding, reported openly.

-"""RQ3 companion instrument-validation gate (`rq3-companion-run-brief.md` §3-4).
-
-DRY, SYNTHETIC-ONLY, OFFLINE calibration of the churn-resilient selector arm. It
-replays the pinned churn schedule under each selector strategy via the pure
-``run_selection`` (no engine, no traffic, no confirmatory record read) and reports
-the RQ3 GO gates that BLOCK the confirmatory battery:
-
-  1. **Churn-bites gate** (§4). At the pinned ``kill_prob_pct = 30``, ``steps = 20``
-     the churn must actually bite — circuits genuinely lose hops and rebuild
-     (non-zero drops/rebuilds). If the drop rate were trivially zero, the
-     throughput-retention and rebuild-classifier tests would be degenerate → STOP.
-  2. **Rebuild-classifier calibration gate** (§3.3). Calibrated on labelled control
-     signals BEFORE the confirmatory cells: churned (``kp=30``) vs the LOW-CHURN
-     baseline (``kp=5``) must be separable on the rebuild-interval-gap signal
-     (AUC≈1), while baseline-vs-baseline must be indistinguishable (AUC≈0.5). Not
-     fit to confirmatory data.
-  3. **Agent-selector reproducibility** (§4). Same seed + churn history → byte-
-     identical selector decisions (the deterministic local heuristic arm here; the
-     Ollama confirmatory arm is reproducible via its committed decision-cache
-     replay, exercised in the unit tests — no network in this gate).
-  4. **Entropy calibration (inherited)** — Shannon plug-in of N equiprobable
-     senders is exactly log2(N).
-
-HARD HOLD: the confirmatory RQ3 battery does not run until items 1 AND 2 are green

-"""RQ3 confirmatory analysis — reads the SEALED live-docker battery, applies the
-FROZEN prereg §6 plan, and computes the authoritative Holm-7 over the whole family.
-
-This is the RQ3 analogue of ``rq2p3_confirm.py``: it does **not** re-specify anything.
-It loads the immutable ``rq3-battery-results.json`` (the operator-gated live-docker
-run) and the pinned params in ``docs/rq3-companion-run-brief.md`` and computes the three
-frozen RQ3 confirmatory tests, each as an **effect + BCa 95% CI** (never a bare p; the p
-is carried only to order the Holm family, per prereg §6):
-
-  * **RQ3-P1-perf** — throughput-retention margin: mean retention(agent) −
-    max(mean retention(static), mean retention(random)); perf holds iff the CI **lower**
-    bound ≥ +10 pp (frozen gate).
-  * **RQ3-P1-latency** — added-latency(agent) = median e2e latency(agent) −
-    min(median latency(static), median latency(random)) [the faster / min-latency baseline
-    arm, run-brief §3.2]; anonymity-latency budget holds iff the CI **upper** bound ≤ 100 ms.
-  * **RQ3-P2** — rebuild-classifier AUC separating the agent selector's per-run mean
-    inter-rebuild-gap signal from the pooled baseline selectors' signal (the fingerprint
-    question, §1(b)); anonymity holds iff the CI **upper** bound ≤ 0.60.
-  * **RQ3-P3** — logical AND: CONFIRM iff (P1-perf ∧ P1-latency) ∧ P2; else H0.
-
-The BCa machinery is the frozen ``stats`` toolkit — this harness only *drives* it at the
-run level (resample whole runs, the confirmatory grouping unit) via a generic multi-arm
-bootstrap that mirrors ``stats.two_sample_diff_ci`` (independent per-arm resampling, a
-combined leave-one-out jackknife, ``stats._bca_endpoints``). No frozen instrument is edited.
-
-**Authoritative Holm-7.** Once all seven confirmatory p-values exist, this computes the
-exact ``stats.holm_bonferroni`` step-down over the frozen size-7 family
-{RQ1-P1, RQ1-P2, RQ2-P1, RQ2-P3, RQ3-P1-perf, RQ3-P1-latency, RQ3-P2}. The four prior
-p-values are read from the SEALED lead record (RQ1-P1, RQ1-P2, RQ2-P1) and the SEALED
-RQ2-P3′ mechanism record (RQ2-P3 slot = its primary H1-pooled Spearman ρ — the direct
-operationalization of the frozen single-slot "Spearman ρ between concentration and H";
-the lead's degenerate as-instrumented RQ2-P3 is superseded by the mechanism-corrected
-result, per operator decision D3). This Holm-7 is the authoritative final correction and
-supersedes the lead paper's deliberately conservative *partial* embedding; both remain
-valid, the partial never under-corrects.

-Faithfulness of the RQ1-P1 fast path
-------------------------------------
-RQ1-P1's pooled (entry,exit) pair set is ~75 000 units; the frozen
-``stats.bootstrap_ci`` BCa path does an O(n) leave-one-out jackknife (each fold an
-O(n²) rank-AUC), which is structurally intractable at that scale. We therefore run
-a *performance-faithful* bootstrap (:func:`_bootstrap_auc_ci`) that reproduces the
-frozen ``stats.bootstrap_ci`` **bit-for-bit** — the SAME ``random.Random(seed)``
-resample sequence, an AUC provably identical to the frozen detector
-(:func:`_fast_auc`, verified against ``detectors.auc``), the frozen
-``_bca_endpoints`` / ``_percentile`` for the interval, and a vectorised
-leave-one-out jackknife whose per-fold value equals the frozen per-fold recompute.
-``--verify`` asserts this equals ``stats.bootstrap_ci`` on a subsample. The other
-three tests use the frozen ``confirm.*`` functions unchanged.

-"""Pre-registered inferential statistics for the RQ1/RQ2 confirmatory analysis.
-
-This module is the *turnkey* implementation of the frozen prereg §6 analysis plan
-(`sor-consent-prereg.md`), written **before** any confirmatory data exists so the
-analysis precedes the data (`rigor-standards §Statistics`). It computes nothing
-study-specific by itself — it is a small, stdlib-only inference toolkit:
-
-  * :func:`bootstrap_ci` / :func:`two_sample_diff_ci` — BCa (bias-corrected and
-    accelerated) bootstrap 95% CIs, 10,000 resamples by default, with a percentile
-    fallback when the acceleration/bias terms are degenerate (§6: "Bootstrap:
-    10,000 resamples, BCa intervals; seed spot-check");
-  * :func:`miller_madow_entropy_bits` — plug-in Shannon entropy with the
-    Miller–Madow finite-sample bias correction (§3 estimator [APPROVAL]);
-  * :func:`spearman` — Spearman rank correlation (RQ2-P3 mechanism test);
-  * :func:`holm_bonferroni` — Holm step-down multiplicity correction over the
-    frozen confirmatory family, with an explicit ``family_size`` so a lead paper
-    that reports a subset of the 7 pre-registered tests still corrects against the
-    full family (§6; never re-optimised to the reported subset).
-
-It performs no I/O, moves no traffic, and spawns no engine. Resampling is seeded
-(``random.Random(seed)``) and the seed is returned in every :class:`CIResult`, so
-a CI is reproducible and the §6 three-seed spot-check is mechanical.

-  * **RQ1 bridge=on+padding** — bridge on, plus the R1 PADDING stream drives
-    cover traffic on the path (``padding_applied``).
-  * **RQ2 1house-N** — single house sized to the **matched-N** node count.
-  * **RQ2 bridge-federated** — entry/exit in *different* houses joined by a

-"""Confirmatory-battery orchestration for the RQ1+RQ2 lead paper.
-
-This is the *start-line* orchestration layer: it enumerates the frozen prereg §2
-confirmatory cells for RQ1 and RQ2, derives each run's seed by the frozen §4 rule,
-lays out the §2 randomized/interleaved run schedule, and can execute a **DRY
-provenance pass on fixtures** to prove the pipeline emits schema-valid, checksummed
-R2/R3 provenance and that a seed reproduces its circuit-build sequence.
-
-It deliberately does **not** collect confirmatory data: the DRY pass replays the
-deterministic fixture event stream (no engine, no traffic — the containment-safe
-`events.replay_*` path), and the confirmatory battery itself is the human gate.
-The live 3-hop delivery of a real cell is driven separately by
-`forwarder.run_circuit_fixture` on the isolated grid, only after operator go.
-
-Frozen inputs honoured here (never redefined):
-  * base seed **S0 = 20260719** (§4);
-  * **R = 30** runs/cell, **C = 50** circuits/run (§4);
-  * RQ1 cells = bridge {off, on, on+padding} at single-house/static; RQ2 cells =
-    topology {1-house-N, bridge-federated, directory-federated} at bridge-off/
-    static, matched-N (§2). bridge-off+padding is a **declared N/A** (not run).
-
-The one operationalisation this module *defines* (the frozen §4 text gives the
-formula abstractly, not a byte encoding): the per-run seed is
-``SHA256("<S0>|<cell_id>|<run_index>")`` big-endian first 8 bytes → u64. This
-binding is documented in the emitted plan artifact so it is auditable and is a
-harness detail, not an edit to any frozen threshold.

-"""R5 — In-band consent handshake + X25519 hop credentials (Python mirror).
-
-This is the bit-for-bit Python counterpart of ``hh/src/sor/consent.rs`` and the
-sealed-box in ``hh/src/crypto.rs``. Recruitment into a SOR circuit is opt-in and
-signed: a host broadcasts a signed ``{"_sor":{"op":"request",...}}`` control
-frame (invisible to the zero-knowledge server); each node renders accept/reject;
-on accept the node returns an ephemeral hop credential **sealed to the host's
-X25519 key only**, so no third party — not even another room member or the relay
-— can read it. Requests are signed with the Ed25519 persona and verified before
-anything is accepted: an unsigned or forged request is rejected and never yields
-a circuit entry.
-
-Wire/crypto contract (mirrors the Rust; never change in place):
-
-    epk, esk = ephemeral X25519 keypair (fresh per seal -> forward secrecy)
-    shared   = X25519(esk, recipient_pub)
-    key      = HKDF-SHA256(ikm=shared, salt=epk||recipient_pub, info=b"sor-hop-cred-v1")[:32]
-    token    = Fernet(urlsafe_b64(key)).encrypt(plaintext)
-    sealed   = base64(epk) || "." || fernet_token
-
-This module performs no I/O, opens no socket, and stands up no forwarder — those
-are R4, gated by the isolated-engine assertion. It only decides *who* may be
-recruited and mints the per-hop secret. The frame parser never raises on
-arbitrary input (mirrors the never-panic discipline of ``net.rs``/``consent.rs``).

-"""Confirmatory data-collection executor — the human-gated live data run.
-
-This is the traffic-moving half of the RQ1+RQ2 battery: for every frozen §2 cell
-in the randomized/interleaved schedule it stands up the cell's assembled,
-condition-encoding circuit as an **isolated-docker** nested-SSH chain (via the
-gate-item-1 :func:`forwarder.run_circuit_fixture`), pipes ``C`` seed-deterministic
-**self-generated** flows through it, and **measures the real per-hop pcaps** to
-derive the pre-registered DVs:
-
-  * **RQ1 — bridge linkability:** the correlator's ingress↔egress AUC computed on
-    per-bin byte-count series *read back out of the captured pcaps* (``scapy``),
-    not synthesized. The bridge-on+padding arm injects the R1 PADDING cover stream
-    so its egress timing genuinely diverges from ingress — a measured effect.
-  * **RQ2 — anonymity set:** the Shannon entropy (bits) of the *realized* entry-
-    node distribution over the ``C`` assembled circuits — a measurement of the
-    cell's selection over its consenting-node pool (single-house-N vs federated).
-
-Containment (CLAUDE.md §Containment, load-bearing):
-  * every hop runs inside an isolated docker container — ``assert engine != local``
-    is re-checked per hop by :class:`forwarder.ForwarderPlan`; the host never
-    forwards. Only self-generated fixture bytes move, between our own containers.
-  * **no DV is ever fabricated.** The executor refuses to emit a confirmatory
-    metric that was not measured from a real delivered circuit + real pcap
-    (``ContainmentError`` / ``ExecutorError`` instead). It is the anti-fabrication
-    counterpart to the launcher guard.
-
-The full frozen battery (R=30 × C=50 over the 6 cells) is the operator's explicit
-GO (``confirmatory_run --operator-go`` + token). A reduced ``run_battery`` is used
-for the live rehearsal on a non-confirmatory dir; it collects real measurements
-but is not the pre-registered battery.

-"""R6 — Multi-house federation + bridge node (measurement instrument).
-
-Two federation modes, both built as *offline-verifiable logic* (no sockets, no
-engine, no external target — containment stays law; this module moves no real
-traffic and provides anonymity to no one, it only lets the study *measure* two
-trust properties):
-
-1. **directory-federation** (:class:`PeerRoster` / :class:`Directory`). Houses
-   exchange a signed persona roster in a ``{"_sor":{"op":"peer",...}}`` HOUSE-PEER
-   control frame (the same zero-knowledge-server-invisible channel R5 consent uses).
-   A roster is Ed25519-signed by the announcing host and **rejected unless the
-   signature verifies** (mirrors the R5 signature-gate discipline). A host merges
-   validated rosters into a pubkey->house directory and builds a circuit that
-   **spans >= 2 houses**, so no single house's node set covers every hop — the
-   split-knowledge property the RQ2 acceptance check asserts ("no single node's
-   logs contain all hop identities of a circuit").
-
-2. **bridge-member** (:class:`BlindBridge`). A node that has joined two houses and
-   **blind-forwards SOR tunnel bytes only**. It holds *no* room key for either
-   house, so it structurally cannot read either room's chat plaintext — it relays
-   opaque, already-onion-encrypted tunnel payloads verbatim and refuses (cannot
-   open) anything else. Every relayed payload emits an R3 ``bridge_forward`` event
-   (metadata only: circuit id, byte count — never plaintext).
-
-Determinism comes from the R1 ``SorRng`` so a federated path is reproducible from
-its seed alone. Signing/verification reuses the R5 persona primitives verbatim.

-"""RQ3 confirmatory battery — operator-gated LIVE launcher (triple-locked).
-
-The RQ3 family (RQ3-P1-perf, RQ3-P1-latency, RQ3-P2) is part of the **frozen LEAD
-prereg** (`sor-consent-prereg.md` §3/§6, family-of-7); the companion run-brief
-(`docs/rq3-companion-run-brief.md`) pins the churn params (kp=30, steps=20) and the
-selector arms. This launcher is the RQ3 analogue of ``confirmatory_run.py``: it
-collects the confirmatory battery ONLY behind the same triple-lock the lead battery
-uses, because the RQ3-P1-latency DV is a **real end-to-end measurement** on isolated
-docker circuits — nothing here is fabricated.
-
-Triple-lock (all three or refuse):
-  1. **Operator token** — ``SOR_CONFIRMATORY_GO=1`` in the environment.
-  2. **Frozen-prereg SHA-256** — the on-disk lead prereg still hashes to the pinned
-     value (``confirmatory_run.verify_freeze``); no run against an unfrozen/edited prereg.
-  3. **Isolation** — ``assert_isolated(engine)`` (``engine != local``); every hop runs
-     in an isolated docker container, never on the host (CLAUDE.md §Containment).
-
-Green-preflight preconditions (checked, not fabricated): the two RQ3 calibration
-gates (churn-bites + rebuild-classifier) already pass; the grid is up with >=1
-isolated engine host; the ``sor-hop`` image is present; a 1x1x2 live rehearsal
-delivered. Then ``executor.run_rq3_battery(live=True)`` runs the full frozen
-schedule (selector ∈ {static, random, agent} × pinned churn, R runs × C circuits) —
-cells are NOT trimmed. Progress: per-run ``rq3-run.json`` sidecars appear under the
-data dir; completion: ``rq3-battery-results.json`` is written once at the end.

-"""R7 — Path selector that rebuilds circuits under churn.
-
-The selector consumes a churn schedule (``churn.py``) and, whenever a live circuit
-loses a node to a kill, **rebuilds** it from the currently-live pool. The rebuild
-decision is a pluggable :class:`SelectorPolicy` so the RQ3 arms can be swapped
-without touching the replay loop. Three built-in strategies, all deterministic
-and offline:
-
-  * ``static``  — canonical-order pick (stable, no randomness);
-  * ``random``  — seeded SELECTOR-stream pick from the live pool;
-  * ``agent``   — an agent policy. The default backend is a *local* stability
-    heuristic (prefers nodes that have churned least). A reproducible
-    local-open-source-model backend (Ollama, temp=0, seed-pinned, decision-cached)
-    lives in ``agent_selector.py`` and is selected with ``agent_backend="ollama"``.
-    The paid frontier-model / Claude Code arm is **human + budget gated** (GOAL
-    autonomy envelope (c)) and is only exposed as an EXPLORATORY stub that makes
-    no external call — it is never wired as a confirmatory arm here.
-
-The R7 acceptance predicate this satisfies: under a fixed churn seed the selector
-rebuilds every dropped circuit (as long as the live pool can supply ``hops``
-nodes). Rebuild activity is emitted as R3 ``rebuild_start``/``rebuild_done`` +
-``churn_kill``/``churn_spawn`` events when an :class:`EventLog` is supplied.

+# Native harness — live command-entry findings + nudge-loop design
+
+**Date:** 2026-06-10
+**Context:** Evaluating the `native` tool-calling harness (`cmd_chat/agent/bridge.py`,
+`_run_native`) on its ability to drive shell commands into the shared podman/Kali
+sandbox, on a CPU-only box (no GPU). Two prior fixes were live-validated here and
+committed in `a0aa14d`: §3 PTY-sentinel (`_run_shell_in_pty`) and `NATIVE_CONTEXT=4`.
+
+## Test setup
+
+- Fresh room, podman sandbox (`hack-house` container), `/grant ai` drive.
+- Models compared: `qwen2.5:3b` (1.9 GB, prior default) and `qwen2.5-coder:7b`
+  (4.7 GB, pulled for this test). `deepseek-r1:latest` and `westenfelder/NL2SH`
+  were ruled out — both **reject Ollama's `tools` field** (`HTTP 400 "does not
+  support tools"`), so they degrade to the simple injector and can't exercise the
+  native loop.
+- Each task verified against **ground truth** (podman exec into the container),
+  not just the chat/PTY surface.
+
+## Results: qwen2.5:3b vs qwen2.5-coder:7b
+
+| Behaviour | qwen2.5:3b | qwen2.5-coder:7b |
+|---|---|---|
+| Single command (`whoami`) | PASS | PASS |
+| write+run (`hello.sh` date+hostname) | PASS, accurate summary | PASS |
+| **Multi-step** (mkdir→write→list) | **FAIL** — stalled after step 1 ("ok, let's proceed to the next step") | PASS — chained make_dir→write→read, completed |
+| **Recover from mid-task error** | FAIL — gives up | INCONSISTENT — recovered from `[unknown tool make_dir]`, but on `greet.sh` skipped chmod, hit exit 126, then **stopped** |
+| Tool-schema discipline | clean | hallucinated a `make_dir` tool (not in schema) — wasted a turn (`[unknown tool make_dir]`, bridge.py:597) |
+| Final summary quality | vague ("I will proceed…") | empty → `(done)` fallback, or raw advice text |
+| Latency (CPU, no GPU) | ~20–40 s/task | ~2–4× slower, 30–90 s/turn |
+
+### Failure modes observed (both sizes)
+
+1. **Early termination on multi-step** (3B dominant): the model emits filler text
+   with no tool call mid-task; the loop reads "text + no tool call = done" and stops.
+   The remaining steps never run.
+2. **Give-up on unresolved non-zero exit** (both sizes): after a failing command
+   (exit 126/127), the model emits a summary/advice instead of fixing the cause.
+   greet.sh left at mode 644 (never chmod'd) despite the task saying "make it
+   executable".
+3. **Tool hallucination** (7B): invented `make_dir`; the schema only has
+   run_shell/write_file/read_file.
+
+### Root cause in code
+
+`_run_native`, bridge.py:739–741:
+```python
+if not calls:
+    final = (text or "").strip()
+    break        # ANY text-without-toolcall ends the task
+```
+NATIVE_SYSTEM (line 111–113) *also* tells the model to signal completion this exact
+way. So one signal — "text, no tool call" — is overloaded to mean BOTH "done" and
+"stalling/thinking". Disambiguating it is the fix.
+
+**Takeaway:** a bigger model buys multi-step persistence (the 3B's main flaw) but
+does NOT eliminate the give-up-on-error mode, and costs heavy latency. A nudge loop
+that keys off **exit codes** (not just filler text) earns its keep at both sizes.
+
+## Research: how Goose & opencode structure loop termination
+
+(Source read directly from clones; key files cited.)
+
+- **Goose** (`crates/goose/src/agents/agent.rs`): tracks `no_tools_called`
+  (line 1801). When true it does NOT just stop (lines 2232–2316) — in
+  structured/goal modes it injects a continuation nudge
+  (`FINAL_OUTPUT_CONTINUATION_MESSAGE` = "You MUST call the final_output tool
+  NOW…") and loops. Completion is an **explicit terminal tool**
+  (`recipe__final_output`, `final_output_tool.rs`). Vanilla chat with no
+  recipe/goal does fall through to text-as-done, but every structured path
+  overrides that. Bounded by `max_turns`.
+- **opencode** (`packages/opencode/src/session/prompt.ts:1156–1183`): exits only
+  when finish is a real stop reason **AND** it independently re-derives that there
+  are no pending tool calls from the parsed message parts — comment: *"Some
+  providers return 'stop' even when the assistant message contains tool calls."*
+  Hard step cap (`maxSteps`) with a wind-down message (`MAX_STEPS`,
+  `prompt/max-steps.txt`); structured mode forces `toolChoice: "required"`.
+- **Canonical / Cline-Roo**: weak-model harnesses favour an explicit completion
+  action (`attempt_completion`/`submit`) over trusting "empty tool_calls = done".
+- **Recommendation from research:** go structural, not filler-heuristic ("a losing
+  arms race"); nudge on text-without-completion; a hard cap is the only
+  unconditional exit; derive "did a tool get called" from parsed parts, not
+  `finish_reason` (qwen on CPU is unreliable there — it leaks tool calls as
+  `<tool_call>` text in `content`; already handled by
+  `OllamaProvider._extract_text_tool_calls`).
+
+## Design: dynamic nudge loop (output-aware, structural terminator)
+
+Structural termination via a **`DONE:` text sentinel** rather than a 4th tool.
+Divergence from the research's "add a done tool", justified for THIS model:
+qwen-on-CPU already mis-emits structured tool calls (leaks as `<tool_call>` text;
+the 7B even hallucinated `make_dir`). A 4th tool invites the same malformation and
+competes for attention; a `DONE:` prefix disambiguates the existing text channel at
+zero schema cost. This is opencode's "require an explicit marker, don't trust the
+implicit stop", applied to the text channel.
+
+Changes in `_run_native` (bridge.py):
+
+1. **NATIVE_SYSTEM** (line 111–113): replace "reply with a summary and DO NOT call
+   a tool" with → *"When and ONLY when the task is fully done, reply with one line
+   starting `DONE:` and a one-sentence result. Otherwise you MUST call a tool."*
+2. **Track loop state:** `did_action` (any tool ran), `last_rc` (parse the `exit=`
+   already formatted by `_run_shell_in_pty`), `nudges=0`.
+3. **Replace the bare `break` (739–741) with a verdict gate:**
+   - text starts with `DONE:` → **done** (fast path, no nudge)
+   - `last_rc` ∉ {0, None} and no `DONE:` → **stalled** (unresolved error)
+   - no `did_action` → **stalled** (pure talk)
+   - filler regex (`let's proceed`, `next step`, `i will`, trailing colon) and no
+     `DONE:` → **stalled**
+   - else (substantive text, action happened, no error) → **accept as done** — the
+     single heuristic, on the SAFE side, so finished tasks aren't nudged every time
+     (protects CPU latency, the cost a pure-structural form would incur here).
+4. **On `stalled`:** append an output-aware, Goose-style nudge and `continue`,
+   bounded by `MAX_NUDGES = 2` (separate from the productive `max_turns` so real
+   multi-step work isn't starved):
+   > *[if last_rc≠0:]* "The last command exited {rc} (failure) — fix that first
+   > (e.g. `chmod +x` before running a script)." + "You haven't signalled
+   > completion. If `{task}` is fully done reply `DONE: …`; otherwise call the next
+   > tool now — act, don't describe."
+5. **Wind-down:** on the final turn, inject "reply `DONE:` with your result now"
+   (opencode's `MAX_STEPS` pattern).
+6. **Keep** `_extract_text_tool_calls` (already present) — opencode's "derive tool
+   calls from parsed parts, not finish_reason" lesson, which this model needs.
+
+Fixes mapped to observed failures: 3B early-stall → nudged to continue; give-up on
+error (both sizes) → nudged with the exit-code-aware message; over-nudging finished
+tasks → avoided by the `DONE:` fast path + safe-side accept.
+
+## Live validation (qwen2.5:3b, post-implementation)
+
+Ran the two prior failure cases against the freshly-built loop; ground truth via
+`podman exec hack-house`.
+
+- **Multi-step (`mkdir proj3 → write notes.txt → list`): PASS — fixed.** Previously
+  stalled after step 1; now chained write_file → `ls -1 proj3` to completion.
+  Ground truth: `proj3/notes.txt` exists, contents `hello world`. The 3B's dominant
+  failure mode is resolved by the loop alone (no model upgrade needed).
+- **Nudge fires on non-zero exit: confirmed.** On the `greet.sh` case the PTY mirror
+  showed `▸ (nudge: finish the task or reply DONE:)` after a 126, i.e. the
+  output-aware re-prompt triggered structurally as designed.
+- **Give-up-on-error is model-bound, not loop-bound.** The 3B still can't *recover*
+  the greet.sh task even when nudged: across runs it wrote self-referential content
+  (`echo "Hello, world!" > greet.sh`), its `chmod +x` didn't stick (file left 644),
+  and in one run it leaked a bare `write_file proj3/greet.sh …` tool call **as
+  summary text** (not the `<tool_call>` JSON form `_extract_text_tool_calls`
+  handles). These are 3B capability limits, consistent with the 3B-vs-7B table —
+  the loop's job is to detect and report them honestly, not to make a weak model
+  competent.
+
+### Honesty hardening added after live test
+
+The weak 3B routinely *claims* success it didn't achieve ("written, made executable,
+and run successfully" after a 126; "Created greet.sh… ran it" with nothing on disk).
+Echoing that prose as the final summary is actively misleading, so the nudge-budget
+exhaustion path no longer trusts it blindly:
+
+- never ran a tool → `[stopped — model described the task but never ran a tool]`
+- left a non-zero exit → `[stopped — last command exited {rc}; task likely
+  incomplete] …`
+- clean, action-backed turn → the model's summary (unchanged).
+
+Offline unit coverage: 23 assertions on `_completion_verdict` / `_parse_exit` /
+`_strip_done` / `_nudge_message`, all pass.
+
+## Benchmark suite + first baseline (`bench/`)
+
+To compare harness/model changes **systematically** instead of eyeballing one-off
+runs, added a ground-truth-graded benchmark: `bench/tasks.py` (a 4-category ×
+easy/medium/hard matrix — shell, code, git, multi) and `bench/run.py` (drives the
+live TUI via tmux, grades each task by a `podman exec` verify snippet, exit 0 ==
+PASS). Tasks run in the agent's real cwd (`/root`) with bare filenames; pinning an
+absolute path instead just measured the weak model's absolute-path discipline and
+drowned out every other signal.
+
+**Runner gotcha (cost real time):** the TUI is a full-screen (alt-screen) app, so
+`tmux capture-pane -S` does NOT yield chat history — only the current viewport.
+The first detector diffed a `@user` reply count and hung once old replies scrolled
+out of view. Fixed by keying completion off the **`is thinking…` footer** (engage →
+sustained-absence), which is viewport-independent.
+
+**Prompt-fairness fix (found via the benchmark):** "…in your home directory" made
+literal-minded models create a `home/` subdir (`/root/home/a/b/c/marker.txt`) or use
+`~/who.txt`; dropped the phrase — bare filenames land in the agent's cwd (`/root`).
+
+### Baselines — four local CPU models (all tool-capable; fixed prompts)
+
+Every candidate was probed first: `qwen2.5(-coder)` at 0.5b/1.5b/3b/7b all accept
+Ollama's `tools` field; `deepseek-r1` and `westenfelder/NL2SH` reject it (HTTP 400 →
+degrade to the simple harness, useless for the native loop), `llava` is vision-only.
+One run each, shared room, CPU-only box:
+
+| model | size | PASS | avg / median s | passed |
+|---|---|---|---|---|
+| qwen2.5:0.5b | 397 MB | 1/12 | 55 / 49 | shell-hard |
+| qwen2.5-coder:1.5b | 986 MB | 1/12 | 67 / 53 | shell-medium |
+| **qwen2.5:3b** | 1.9 GB | 1/12 | **51 / 46** | code-easy |
+| qwen2.5-coder:7b | 4.7 GB | 2/12 | 141 / 106 | shell-easy, multi-easy |
+
+**Takeaways.** All four cluster at **1–2/12 with high variance** (which task passes
+flips run-to-run) — none reliably drives multi-step sandbox tasks in a shared room.
+The **7B doubles nothing**: same pass band at ~3× the latency, so it is not worth it
+on this CPU box. **qwen2.5:3b is the sweet spot** (best speed, no worse quality) and
+stays the default. The low absolute scores are inflated downward by self-contamination
+(each task's `NATIVE_CONTEXT=4` window pulls the previous task's command/summary) — a
+real deployment effect, but it means the suite's job is *relative* regression
+detection, not an absolute capability grade.
+
+Dominant failure modes the summaries exposed, and where they point next:
+
+| failure mode | example | harness-addressable? |
+|---|---|---|
+| bare tool-call-as-text | `write_file ./who.txt`, `mkdir proj`, `git clone …` (esp. 0.5b — nearly every turn) | **yes** — extend `_extract_text_tool_calls` beyond `<tool_call>` JSON |
+| `<native>` / `<tools>` tag leak in summary | `<native> Cloned repository…`, `<tools>` | yes — strip the tag |
+| path hallucination | `/home/qwen253b/conf_count.txt`, `~/` unexpanded | partly (model) |
+| content fabrication | wrote literal `dell` instead of running whoami | no (model capability) |
+
+The first row was hypothesised as the top priority — a pure harness parse gap. The
+benchmark now exists to prove whether fixing it moves the number.
+
+### Parser fix — what the benchmark actually proved (2026-06-10)
+
+Generalised `OllamaProvider._extract_text_tool_calls` to recover a tool-call JSON
+object regardless of wrapper — qwen's `<tool_call>` tags, bare JSON, ```json fences,
+alternate tags (`<tools>`, `<function_call>`), OpenAI `{"function":{…}}` nesting, and
+`parameters`-vs-`arguments`. Gated on the known tool-name set (derived from the
+`tools` schema) so a stray JSON blob in prose — or a hallucinated `make_dir` — can
+never be coerced into an action. 11-case unit check: 8 leak shapes recover, 3
+negatives (prose / unknown tool / random config JSON) ignored.
+
+**Result: it does NOT move the weak-model pass rate.** Three 3b passes went 2 / 1 / 0
+of 12 (prior baseline 1/12 — pure noise); two 0.5b passes went 0 / 0 (prior 1/12).
+
+A direct `/api/chat` probe of 0.5b shows *why* — the hypothesis was wrong about the
+**form** of the leak. The weak models do not emit a JSON tool-call as text. They emit
+either:
+
+  * **malformed structured `tool_calls`** — e.g. `write_file` with `content: null`
+    (the field IS populated; the arguments are just wrong → model capability, not a
+    parse gap); or
+  * **a fenced shell/code block in prose with NO tool call at all** — e.g. content
+    `"…let's proceed:\n```bash\nmkdir -p a/b/c\n```"`, `tool_calls: None`. This is the
+    "[stopped — model described the task but never ran a tool]" case that dominates
+    the 0.5b table.
+
+So the structured-JSON recovery is a correct, safe hardening (it WILL catch a real
+JSON-in-text leak from any model that produces one, and cannot fabricate an action),
+but the failure it was meant to fix is not the failure these CPU models actually have.
+
+**The real harness-addressable lever the data now points to:** recover **fenced code
+blocks** (```bash … ``` / ```python … ```) as `run_shell` calls when the turn carried
+no structured call. That is the genuine form of the weak-model leak. It is a bigger
+safety call than JSON recovery (it executes a block the model wrote as prose, which
+may be illustrative rather than an action), so it is left as an explicit decision, not
+folded in silently.
+
+| failure mode | example | harness-addressable? |
+|---|---|---|
+| malformed structured args | `write_file` with `content:null` | no (model capability) |
+| fenced code in prose, no call | ```` ```bash\nmkdir -p a/b/c\n``` ````, `tool_calls:None` | **yes, but a safety call** — parse fences → run_shell |
+| JSON tool-call leaked as text | `<tools>{"name":…}` | yes — **now handled** (no weak-model effect) |
+| path hallucination | `/home/qwen253b/…`, `/ai/a/b/c`, `~/` unexpanded | partly (model) |
+| content fabrication | wrote literal `octocat`/`dell` instead of running whoami | no (model capability) |
+
+**Other models worth pulling for a non-qwen data point** (different family → different
+failure modes, both with strong native tool-calling): `llama3.2:3b` (~2 GB, peer to
+the 3B) and `llama3.1:8b` (~4.7 GB, peer to the 7B but general-purpose). Probe the
+`tools` field first, then `bench/run.py --model <name>`.
+
+The first two are the clear next harness improvements; the benchmark now exists to
+prove whether they move the number.
+
+### The win — split-tag recovery + greedy decode (2026-06-10)
+
+Two more harness changes, and the first to actually move the number:
+
+1. **Greedy decode for the tool loop** — `complete_with_tools` now sends
+   `temperature: 0` (scoped to the tool loop; chat keeps default sampling). At
+   Ollama's default 0.8 the weak model sampled away from the tool-call format into
+   prose/fabrication. The nudge prompt changes between turns, so temp 0 still escapes
+   a failed state on retry — it just stops the creative drift.
+
+2. **Split-tag recovery** — temp 0 made 0.5b's leak *deterministic*, which exposed its
+   real shape: NOT a JSON object with a `name` key, but the name in a tag and the args
+   in a SEPARATE object — `<tools>write_file</tools>{"path":…,"content":…}`,
+   `<tools>run_shell</tools>{"command":…}` — ~5 of 12 tasks per run. `_NAMED_TAG` in
+   the provider now pairs that tag-name with the following args object (gated on the
+   known tool set, so it still can't fabricate an action).
+
+3. **Fenced recovery** (bridge) — recover a `` ```bash `` block narrated in prose as a
+   run_shell call, non-destructive only (`FENCE_DESTRUCTIVE` guard). Fires on the
+   prose-leak turns; a no-op where the model emits structured calls.
+
+**Result — the effect is concentrated on the weakest model, as theory predicts** (the
+smaller the model, the more it leaks malformed text instead of structured calls; a
+bigger model emits proper calls and fails on capability/content, which no parser can
+fix):
+
+| model | baseline | optimized (2 runs) | note |
+|---|---|---|---|
+| qwen2.5:0.5b | 1/12 | **4/12, 3/12** | split-tag leak dominates → big lift |
+| qwen2.5:3b | 1/12 | 2/12, 0/12 | emits proper calls → unchanged (noise) |
+
+Ablation on 0.5b: structured-JSON-only `0/0` → fenced+temp0 `2/0` → +split-tag `4/3`.
+Split-tag recovery is the dominant contributor; temp 0 is what made the leak
+consistent enough to parse. Net: the harness now extracts ~3× more signal from the
+0.5b, and temp 0 is a sound default for the tool loop on any model.

-# Note — the RQ2-P1 "shrink" is plausibly a unique-bridge instrument artifact
-
-**Status:** on-record analysis note, 2026-07-21. Does **not** edit the frozen prereg or the
-committed lead paper; it documents a mechanism concern for the record and motivates the
-`rq2p3-mechanism-prereg.md` follow-up. Author: overseer, post-lead-paper review.
-
-## The finding
-
-The lead paper (RQ2-P1) reports federation **shrinks** the per-circuit anonymity set
-(ΔH = −0.96 bits pooled; −3.63 bits bridge-federated-only, exploratory). Tracing the ratified
-posterior mechanically shows this shrink is **largely forced by the instrument**, not by a
-substantive funnelling phenomenon:
-
-1. The adversary's observation is `exit_signature = (exit_house, bridge_label)`
-   (`confirm_load_rq2.py:exit_signature`).
-2. The anonymity set for circuit *i* is the distinct **entry** nodes among circuits sharing
-   *i*'s signature (`observation_consistent_sizes`): `m_i = |{entry(j) : sig(j) == sig(i)}|`.
-3. The bridge-federated instrument assigns a **fresh bridge per circuit seed**
-   (`assembler.py:_bridge_label(seed)`), so **every circuit's `bridge_label` is unique** ⇒
-   every `exit_signature` is unique ⇒ each group has size 1 ⇒ **`m_i = 1` ⇒ `H_i ≈ 0`.**
-
-So bridge-federated collapses to near-zero entropy **because each circuit was handed its own
-bridge**, making its signature a unique identifier. That is the *same* degeneracy that made
-RQ2-P3 untestable (zero-variance concentration) — here it manifests as an artificially low H
-that drives ΔH negative.
-
-## Why this likely inverts under realistic bridge reuse
-
-Introduce a finite shared bridge **pool**: many circuits share a bridge ⇒ shared signature ⇒
-`m_i` = distinct entries across all of them ⇒ **larger set ⇒ higher H**. Under this posterior
-a shared bridge behaves as a **mix**: more concentration plausibly *raises* anonymity — the
-opposite of the naive "funnelling shrinks the set" story. The mechanism study
-(`rq2p3-mechanism-prereg.md`) tests this **two-sided**; the mechanical prediction is mix
-(ρ > 0), the naive prediction is funnel (ρ < 0).
-
-## Consistency check against observed numbers
-
-- Directory-federated cell (no bridge hop → `bridge_label = None`, shared signature):
-  observed `rq2_anonymity_entropy_bits = 5.6439 = log₂(50)` — **maximal** entropy, all 50
-  senders in the set. Confirms shared signatures give large sets.
-- Bridge-federated (unique bridge per circuit): H ≈ 0, consistent with the exploratory
-  ΔH = −3.63. The pooled −0.96 is the average of a high-H directory arm and a ≈0-H bridge arm.
-
-## Integrity status
-
-- The lead paper is **not wrong or dishonest**: §7 already flags RQ2 as conditional on the
-  posterior construction and RQ2-P3 as an unresolved mechanism. This note **sharpens** that
-  caveat from "conditional" to "the specific shrink magnitude is mechanically forced by the
-  fresh-bridge instrument."
-- **No silent edit** to the committed paper or frozen prereg. If the mechanism study confirms
-  mix (ρ > 0), the honest outcome is a companion result that **qualifies/corrects** the lead
-  RQ2-P1 headline — reported openly, per the null-results-are-results rail.
-- This strengthens the body of work: it is exactly the kind of artifact a pre-registered,
-  frozen-detector method is supposed to expose rather than bury.

-# Pre-registration (DRAFT) — RQ2-P3 funnelling-mechanism study
-
-> **STATUS: FROZEN — operator freeze sign-off 2026-07-21** (Andre delegated per-gate command
-> authorization to the overseer 2026-07-21; executed by overseer). Design + parameters
-> operator-approved 2026-07-21 (grid B∈{2,4,8}×α∈{0,1,2}; run-level cluster bootstrap;
-> two-sided/direction-agnostic). The SHA-256 of this file is recorded in
-> `rq2p3-mechanism-prereg.sha256` (§10). The confirmatory battery MAY now run; no hypothesis or
-> parameter may change post-freeze.
-> This is a **new study with its own slug** (`sor-consent-rq2p3`). It **does not modify**
-> the frozen lead prereg (`sor-consent-prereg.md`, SHA
-> `f22331a72e0d0ccf38b787e63acabbe9d666456ec76076787a6d545c3193425b`), whose RQ2-P3
-> result stands as reported ("inconclusive — not testable as-instrumented").
-
-## 0. Why this study exists
-
-The lead paper found federation **shrinks** the per-circuit anonymity set (RQ2-P1,
-ΔH = −0.96 bits, Holm-significant) but could **not** test the *mechanism* (RQ2-P3): the
-bridge-federated instrument assigns a **fresh willing bridge per circuit seed**
-(`assembler.py:131`, `_bridge_label(seed)`), so every circuit routes through a distinct
-bridge, top-3 concentration is constant (`c_i = 1/C`), the covariate has **zero variance**,
-and Spearman ρ is undefined (`stats.spearman` returns 0.0 by construction). The lead paper
-reported this honestly as an as-instrumented degeneracy, not a null of a well-posed test.
-
-**The mechanical insight this study exists to test (see `note-unique-bridge-artifact.md`).**
-The adversary's observation is `exit_signature = (exit_house, bridge_label)`, and the
-per-circuit anonymity set `m_i` = the distinct entry nodes among circuits sharing that
-signature (`confirm_load_rq2.py`). A **fresh bridge per circuit ⇒ every signature is unique
-⇒ group size 1 ⇒ m_i = 1 ⇒ H ≈ 0.** That — not funnelling — is why bridge-federated produced
-H ≈ 0 and drove the lead ΔH negative. Introduce a **finite shared pool** and many circuits
-share a bridge ⇒ shared signature ⇒ larger set ⇒ **higher H**. Under this posterior a bridge
-is a **mix**: more concentration plausibly *raises* anonymity, the opposite of the naive
-funnel story. So this study is, honestly, **a test of whether the lead paper's "shrink" is a
-unique-bridge artifact** — and it may *qualify or correct* the lead RQ2-P1 headline.
-
-This study re-instruments the willing-bridge layer with a **finite pool + skewed
-willingness** so concentration genuinely varies, and — the key upgrade — treats
-concentration as a **manipulated independent variable** (a dose-response design) rather than
-a passive covariate. The direction is left **two-sided**: the naive prediction is funnel
-(ρ < 0); the mechanical prediction under the ratified posterior is mix (ρ > 0). We pre-commit
-to reporting whichever the data shows, including a correction to the lead result if warranted.
-The analysis code (`bridge_concentration`, `rq2_p3_funnel`) is already correct; only the
-*instrument* and this *prereg* are new.
-
-## 1. Blinding & integrity posture (read first)
-
-- **This study is NOT blind to the RQ2-P1 shrink direction** (the lead paper is published).
-  Mitigations that keep it honest: (a) the funnelling hypothesis was **pre-stated as a live
-  mechanism** in the lead paper's introduction, not invented post-hoc; (b) the confirmatory
-  targets below are **two-sided**; (c) concentration is a *manipulated* IV, so the test is a
-  designed dose-response, not a re-slice of the lead data.
-- **The lead RQ2-P1 result is NOT re-litigated here.** Any ΔH this pool instrument produces
-  is labeled **EXPLORATORY / replication**, never a re-run of the frozen RQ2-P1.
-- **No detector retuning.** The entropy estimator, posterior construction, and Spearman path
-  are inherited **unchanged** from the frozen lead pipeline; only bridge assignment changes.
-
-## 2. Research question & hypotheses
-
-**RQ2-P3′.** Within the consent-gated bridge-federated topology, does willing-bridge
-**concentration** causally reduce the per-circuit anonymity set (funnelling)?
-
-- **H1 (within-cell association, two-sided).** Spearman ρ between per-circuit top-3 willing-
-  bridge concentration `c_i` and per-circuit entropy `H_i`. **Funnel** iff BCa 95% CI < 0;
-  **mix** iff CI > 0; **inconclusive** iff CI spans 0. Direction is *not* presumed.
-- **H2 (dose-response, two-sided).** OLS slope β of H on realized top-3 concentration, over
-  **per-run mean points** (9 cells × 30 runs = 270 clustered points), cell-level BCa CI.
-  **Funnel** iff slope CI < 0; **mix** iff slope CI > 0.
-- **H3 (joint, direction-agnostic).** Mechanism **RESOLVED** iff H1 and H2 agree in sign and
-  both exclude 0; the *sign* is the finding (funnel vs mix). **Unresolved** if either spans 0.
-
-## 3. Instrument change (the only new code)
-
-Replace the per-seed fresh bridge with a **willing-bridge pool** of size `B` and a fixed
-skewed willingness weight vector, under a **new topology factor** so lead-paper cells stay
-bit-reproducible:
-
-```
-# new assembler branch: topology == "bridge-federated-pool"
-weights   = zipf_weights(B, alpha)                 # fixed from the CELL seed; stable per run
-idx       = weighted_draw(sha256(f"sor-bridge-pool|{circuit_seed}"), weights)
-bridge    = f"bridge#{idx:02d}"                     # B distinct labels, REUSED across circuits
-```
-
-- Weights derive from the **cell** seed (not the circuit seed) so the willingness profile is
-  fixed within a run and circuits genuinely share bridges → concentration varies.
-- Everything else (hop structure, houses, exit-signature grouping, posterior, Miller–Madow H,
-  BCa) is **identical to the frozen lead pipeline**.
-- Touchpoints: `assembler.py` (new branch + pool helper), `battery.enumerate_cells()` (sweep).
-  `confirm_load_rq2.py`, `confirm.py`, `stats.py` are **unchanged**.
-
-## 4. Design matrix (concentration as IV)
-
-Bridge-federated-pool, selector `static`, matched-N, bridge willingness the only manipulation:
-
-- **Pool size** `B ∈ {2, 4, 8}` — 3 levels.
-- **Willingness skew** `alpha ∈ {0 (uniform), 1.0 (moderate Zipf), 2.0 (heavy Zipf)}` — 3 levels.
-- Full 3×3 = 9 concentration cells (each realizes a distinct mean top-3 concentration).
-
-Run order randomized within cell; deterministic from an ordering seed distinct from data seeds.
-
-## 5. Dependent variables
-
-- **Per-circuit H_i** — Miller–Madow entropy of the uniform posterior over the observation-
-  consistent anonymity set (inherited **verbatim** from the frozen lead pipeline).
-- **Per-circuit top-3 concentration c_i** — `confirm_load_rq2.bridge_concentration` (unchanged).
-
-## 6. Sampling, seeds, stopping rule
-
-- **R = 30** seeded runs/cell, **C = 50** circuits/run (matched to the lead study).
-- Base seed **S0 = 20260719**; per-cell seed = `SHA256(S0 ‖ cell_id ‖ run_index)` (matched).
-- **Fixed stopping rule:** all 9 cells × R run to completion. No optional stopping, no interim
-  looks. An uninformative cell is reported **inconclusive**, never extended.
-
-## 7. Instrument-validation gate (boolean; blocks the confirmatory run)
-
-> **Re-worded 2026-07-21, pre-freeze (deviation logged in `stage-05-rq2p3-gate-clarification.md`).**
-> Items 1–2 were originally written under the naive-funnel prior ("pool reproduces the
-> zero-variance degeneracy"; "B=1 → low H"). Both are mechanically wrong under the *ratified*
-> posterior and were corrected **before freeze** — see the §7 scope note below. No hypothesis
-> changed (H1/H2/H3 in §2 stay two-sided/direction-agnostic); only a mis-specified validation
-> gate was fixed. The original dry-pass output that exposed this is cited in the deviation log.
-
-All must pass **before** any confirmatory cell:
-
-1. **Reproduce the lead degeneracy — on the FROZEN branch, not the pool.** The lead
-   zero-variance degeneracy is a property of the **injective fresh-bridge map** (a unique
-   bridge per circuit seed = effectively no reuse). A finite pool of **any** size `B` draws
-   **with replacement**, so birthday collisions make concentration non-constant and ρ defined —
-   a pool **cannot and must not** be expected to reproduce the fresh-bridge degeneracy. The
-   regression check therefore anchors on the actual frozen `bridge-federated` branch
-   (UNTOUCHED): it must still yield **unique exit-signatures → `m_i = 1` → `H_i ≈ 0`, constant
-   `c_i = 1/C`**. That is the real "lead reproduces" teeth.
-2. **B = 1 boundary.** `B = 1` → all circuits share the one bridge → **`c = 1.0`** (keep this
-   concentration tooth). Under the ratified posterior the anonymity set is then **all** circuits
-   sharing the exit house, so `H_i` sits at the **HIGH end (maximal mix)** — the "low H" gloss
-   was the naive-funnel error and is refuted **by construction** here. Expect high H.
-3. **Monotonicity.** Realized mean top-3 concentration is **monotone decreasing in B** and
-   **increasing in alpha**, across the sweep, on a dry (non-confirmatory) calibration pass.
-4. **Entropy calibration unchanged.** H = log₂N on equiprobable synthetic senders (inherited).
-
-**§7 scope note (why items 1–2 do NOT assert an H-vs-c sign).** This gate validates the
-**instrument** — concentration varies monotonically (item 3), entropy is exact (item 4), the
-frozen branch is untouched (item 1), and the B=1 boundary hits `c = 1.0` (item 2). It **must not
-pre-assert the sign of H-vs-concentration**, because that sign *is* the two-sided confirmatory
-question (H1/H2). Baking "expect low H at high concentration" into a validation gate would be
-**funnel-circular**; removing it makes the study **more** rigorous, not less. The confirmatory
-hypotheses in §2 stay two-sided/direction-agnostic — **UNCHANGED**. (Note: the dry calibration
-pass already *previews* a mix, ρ 0→+0.838 across the sweep; this is surfaced openly as an
-exploratory preview and does **not** relax the two-sided pre-commitment.)
-
-If any gate item fails → STOP, do not report; surface as NEEDS-OPERATOR.
-
-## 8. Analysis plan
-
-- Effect size + BCa 95% CI for every test; p never reported alone; 10,000 resamples; α = 0.05.
-- **H1:** `confirm.rq2_p3_funnel(c, H)` per cell + pooled, but resampled with a **run-level
-  cluster bootstrap** (resample whole runs, not individual circuits). Rationale: circuits
-  sharing a bridge have identical `c_i` and correlated `H_i`, so per-circuit resampling
-  pseudo-replicates and falsely narrows the CI (the same defect noted for lead RQ1-P1). The
-  run is the independent unit.
-- **H2:** OLS slope of per-run mean-H on per-run mean top-3 concentration (270 clustered
-  points); BCa CI resampling **over runs within cells** (cluster bootstrap).
-- **Multiplicity:** Holm–Bonferroni over **this study's own family** {H1-pooled, H2-slope}
-  (the lead study's family-of-7 is closed and not reopened).
-- **Confirmatory vs exploratory:** the 9-cell sweep is confirmatory; any per-cell ρ contrast or
-  ΔH replication is labeled EXPLORATORY.
-- **Data exclusion (pre-data):** quarantine only on integrity failure (SHA/pcap mismatch,
-  non-reproducing seed). No performance-based exclusions.

-HARKing; nulls are results). Containment: isolated docker only, self-generated fixture traffic,

-# Execution-freeze / run-brief (DRAFT) — RQ3 companion battery
-
-> **STATUS: PARAMS LOCKED 2026-07-21 — execution plan, NOT a new prereg.** RQ3's hypotheses,
-> gates, and analysis are **already frozen** in `sor-consent-prereg.md` (SHA
-> `f22331a72e0d0ccf38b787e63acabbe9d666456ec76076787a6d545c3193425b`, §3/§4/§6). Writing a
-> "new RQ3 prereg" would be redundant and risk HARKing. This brief (a) **pins the two open
-> `[APPROVAL]` execution parameters** (agent model, churn schedule — both locked below,
-> blind to RQ3 outcomes) and (b) lists the build + gate steps. **GO gate before the
-> confirmatory battery: the rebuild-classifier calibration gate + the churn-bites gate must
-> pass green (§3-4).** Build + synthetic tests MAY proceed now.
-
-## 1. The frozen gates (verbatim — do not restate as new)
-
-Family stays the frozen size-7 {RQ1-P1, RQ1-P2, RQ2-P1, RQ2-P3, **RQ3-P1-perf,
-RQ3-P1-latency, RQ3-P2**}. The three RQ3 tests were always in the family.
-
-| Test | Frozen gate |
-|---|---|
-| RQ3-P1-perf | throughput-retention(agent) − max(static,random): CI lower bound ≥ **10 pp** |
-| RQ3-P1-latency | added-latency(agent): CI upper bound ≤ **100 ms** |
-| RQ3-P2 | rebuild-classifier AUC: CI upper bound ≤ **0.60** |
-| RQ3-P3 | logical AND: CONFIRM iff P1 ∧ P2 (not a new test) |
-
-R = 30 runs/cell, C = 50 circuits/run, fixed stopping rule (no optional stopping / interim
-looks; uninformative cell → inconclusive). All inherited unchanged.
-
-## 2. Open `[APPROVAL]` params to PIN before GO (the actual gate)
-
-The frozen prereg left two items tagged `[APPROVAL] pinned at freeze` — **the `[APPROVAL]`
-tag is still literally present in the frozen text, i.e. neither was concretely substituted.**
-These must be pinned now, blind to RQ3 data:
-
-**(A) Agent selector model ID + weights digest** (§3 L71-73) — **LOCKED 2026-07-21.**
-- Pin: **`qwen2.5:3b`** via local Ollama (`agent_selector.OllamaAgentPolicy`, temp 0,
-  per-run seed, state-hash cache; heuristic fallback on query failure). Record the exact
-  **model tag + SHA-256 weights digest** in every manifest (digest captured at run time).
-- Rails satisfied: **local / open-weight, $0**, no paid-frontier call. The Claude/frontier
-  arm (`ClaudeExploratoryPolicy`) stays **inert / EXPLORATORY / budget-gated** — not wired.
-- **Reproducibility caveat (accepted; must be stated in the paper).** Ollama at temp 0 is
-  **not bit-identical across machines** (quantization / GPU logit drift). The agent arm is
-  reproducible via the **committed decision-log + state-hash cache replay**, *not* via
-  independent model re-execution on other hardware — same honesty class as the RQ1 timing
-  caveat. Commit the decision log + cache as the reproducibility anchor.
-
-**(B) Churn schedule set** (§3 L74, §4) — **LOCKED 2026-07-21.** `churn.churn_schedule(seed,
-nodes, steps, kill_prob_pct)` is implemented and deterministic.
-- Pin: a **seeded set** of schedules — one schedule per run, seed drawn from the same
-  `SHA256(S0‖cell‖run)` family so every run's churn is reproducible and provenance-anchored.
-  **`kill_prob_pct = 30`, `steps = 20`.**
-- **Churn must actually bite (gate, §4).** With these values, confirm on a dry pass that
-  circuits genuinely lose hops and rebuild (non-zero `drops`/`rebuilds` per run). If drop
-  rate is trivially zero, the throughput-retention and rebuild-classifier tests are
-  degenerate — STOP and surface rather than report a zero-variance null.
-
-## 3. Build gaps (hand to the driver in tmux; not built inline)
-
-Verified against the current worktree — what exists vs. what's missing:
-
-**Ready (no work):** `selector.py` static/random/agent all implemented + tested;
-`agent_selector.OllamaAgentPolicy` reproducible; `churn.py` deterministic schedules wired
-into `run_selection()`; `analysis/metrics.py` has `throughput_retention()` +
-`rebuild_classifier_auc()`.
-
-**Missing (build):**
-1. **`battery.enumerate_cells()`** (`battery.py:73`) enumerates RQ1+RQ2 only (6 cells). Add
-   RQ3 cells: `selector ∈ {static, random, agent} × churn-schedule(s)` at the
-   1house/bridge-off control; interleave the control arm like RQ1/RQ2.
-2. **`executor.run_battery()`** — wire RQ3 collection: drive `run_selection()` over the
-   pinned schedule; collect throughput-retention, **added-latency**, and rebuild-event gaps
-   → classifier AUC. **Baselines LOCKED:** added-latency = median e2e latency(agent) −
-   median latency(**min-latency baseline arm**, i.e. the faster of static/random); perf
-   margin uses **max(static, random)** per the frozen gate.
-3. **Rebuild-classifier calibration gate** — calibrate the classifier on labeled
-   churned-vs-low-churn control signals **before** the confirmatory RQ3 battery (same
-   discipline as the RQ1 correlator gate). **Low-churn baseline LOCKED: `kill_prob_pct = 5`.**
-   Gate passes iff churned-vs-baseline is separable (AUC≈1) and baseline-vs-baseline is not
-   (AUC≈0.5). Boolean; blocks the run.
-
-## 4. Instrument-validation gate (boolean; blocks RQ3 confirmatory)
-
-Reuse the frozen 6-item gate spirit, plus RQ3-specific:
-- Rebuild classifier calibrated on control signals (AUC≈1 churned-vs-baseline separable,
-  AUC≈0.5 baseline-vs-baseline) — **not fit to confirmatory cells**.
-- Agent selector **reproducibility check**: same seed + state-hash → byte-identical circuit
-  choice (cache replay), model+digest echoed to manifest.
-- Isolation (`assert engine != local`), provenance integrity (sealed `events.jsonl`).
-
-## 5. Analysis
-
-- Reuse `stage06_run` on the sealed RQ3 data; compute the three RQ3 tests with effect + BCa CI.
-- **Complete the Holm step-down over the full family of 7** now that all seven p-values exist.
-  (The lead paper's 7/6/5/4 was a deliberately conservative *partial* embedding; the companion
-  computes the exact Holm-7 — both remain valid, the partial never under-corrects.) **The
-  companion's Holm-7 is the authoritative final correction over the whole family**, including
-  the lead RQ1/RQ2 tests; RQ1-P1 and RQ2-P1 survive regardless (raw p ≈ 0), but state
-  explicitly that the companion supersedes the lead's partial embedding.
-- Confirmatory vs exploratory labeled; nulls reported honestly (a selector that does **not**
-  beat baselines, or a rebuild pattern that **is** a fingerprint, is the finding).
-
-## 6. QUIC / ssh3 transport arm — stays EXPLORATORY
-
-Frozen as **EXPLORATORY, orthogonal to all three RQs, and not built** (design decision D3;
-§3 L75-78). Recommendation: **defer.** Promoting it doubles every cell + requires a new
-transport substrate for a weak lit-gap. If ever built, carry only as a labeled EXPLORATORY
-latency-sensitivity note — never in the Holm family.
-
-## 7. Rails (immutable, inherited)
-
-Frozen prereg never edited; execution pins recorded here + in manifests; no HARKing; nulls
-are results. Containment: isolated docker only, self-traffic, lab-only. **Budget $0** —
-local open-weight agent only, no paid arm; surface before any spend. Worktree only on
-`feat/sor-consent-relay`. Raw data immutable + SHA-256.

-## Authority (this IS the freeze, not a new choice)
-
-The size-7 family and its disclosure in the lead paper are **pre-registered text**,
-so holding `m = 7` for the reported RQ1/RQ2 subset is compliance, not deviation:
-
-- **Prereg §6 — Multiple-comparison correction [APPROVAL]** (prereg lines ~218–222):
-  *"the confirmatory hypothesis tests across all three RQ families are corrected
-  together by Holm–Bonferroni … Test family (7 confirmatory tests): {RQ1-P1, RQ1-P2,
-  RQ2-P1, RQ2-P3, RQ3-P1-perf, RQ3-P1-latency, RQ3-P2}."* The family is frozen at 7.
-- **Prereg D6** (prereg line ~317): *"the shared prereg + Holm-corrected family are
-  disclosed in whichever papers result (which is more rigorous)."* The lead paper
-  discloses the **same size-7 family** even while reporting only the RQ1/RQ2 subset.
-
-Correcting the reported 4 against `m = 4` would shrink the frozen family after the
-fact — p-hacking the multiplicity down, contrary to §6. Holding `m = 7` is the
-only reading consistent with the frozen text.
-
-## The question
-
-The prereg §6 pre-registers a **confirmatory family of 7** hypothesis tests:
-
-```
-RQ1-P1, RQ1-P2, RQ2-P1, RQ2-P3, RQ3-P1-perf, RQ3-P1-latency, RQ3-P2
-```
-
-The **lead paper (G4 + RQ1 + RQ2, prereg D6)** reports only the first **4**
-(RQ1/RQ2); RQ3's three tests are the severable follow-on (§8). So: when we
-Holm-correct the 4 reported p-values, do we correct against **m = 7** (the frozen
-family) or **m = 4** (the reported subset)?
-
-Correcting against m = 4 would be **p-hacking the multiplicity down**: the family
-was frozen at 7 *before* data, and shrinking it after the fact — because RQ3 is
-being reported later — inflates the reported significance of the RQ1/RQ2 subset.
-That breaks the pre-registration.
-
-## Decision (implemented default)
-
-**Hold the family size at m = 7 for every reported test.** The reported subset
-never shrinks the correction to itself.
-
-Concretely, Holm step-down (`stats.holm_bonferroni`, `confirm.apply_holm`):
-
-- All reported p-values are sorted ascending and assigned ranks `k = 1..R`
-  (`R = 4` reported here).
-- Each gets multiplier `m − k + 1` with **`m = FROZEN_FAMILY_SIZE = 7`**.
-- So the 4 reported tests receive multipliers **7, 6, 5, 4** (smallest p → ×7).
-  The step-down enforces monotone non-decreasing adjusted p-values.
-- `holm_bonferroni` **raises** if `family_size < #reported` — you can never
-  accidentally correct against fewer than the tests you are reporting.
-
-This is a **conservative embedding**: the 4 reported tests are treated as
-occupying the 4 *smallest-multiplier* slots (7,6,5,4) of the size-7 family rather
-than the true unknown slots they would occupy if all 7 p-values were in hand. The
-adjusted p-values are therefore **≥** the values a full simultaneous size-7 Holm
-run would assign to these same tests. We over-correct, never under-correct — the
-honest direction for a subset report.
-
-*Covered by `tests/test_sor_confirm.py::test_apply_holm_corrects_against_family_of_seven`
-(top multiplier == 7; multipliers == [4,5,6,7]) and
-`tests/test_sor_stats.py` (family-size monotonicity + `ValueError` when
-`family_size < reported`).*
-
-## Gate vs. Holm ordering (not conflated)
-
-Every **reported decision** in §6 is a **CI gate** (RQ1-P1 CI excludes 0.5;
-RQ1-P2 ΔAUC CI > 0; RQ2-P1 ΔH two-sided CI sign; RQ2-P3 Spearman ρ CI). The
-bootstrap p-values feed the Holm step-down **only to order it** — no reported
-claim rests on a bare p. Holm is the family-wise multiplicity guard layered on
-top of the pre-registered CI gates, exactly as §6 / rigor-standards §Statistics
-require.
-
-## Operator ruling (2026-07-19)
-
-The operator (Andre) ratified the **conservative embedding**: hold `family_size = 7`,
-report the 4 RQ1/RQ2 tests, multipliers **7, 6, 5, 4**. This is exactly the frozen
-§6 / D6 text above — the harness default now matches the pre-registration.
-
-Two alternatives were considered and **explicitly declined**:
-
-- *Fold RQ3's three cells back in and report all 7 simultaneously.* Statistically
-  clean, but RQ3 was dropped for the lead paper (prereg D6) and would need the
-  paid/agent selector-arm decisions. **Declined:** do not fold RQ3 back.
-- *Full α-splitting / hierarchical gatekeeping.* More powerful, but requires a
-  pre-specified α-allocation the frozen prereg does not contain. **Declined:** not
-  available without a prereg change (which the freeze forbids).
-
-No open human action remains: the implemented default is the ratified one.

-RQ2-posterior clarification — this adds **no construct**: it restates the pairing
-the frozen text already implies for the §6 *paired* bootstrap.
-
-> **Distinction from the RQ2 case.** The RQ2 note filled a genuine gap (the prereg
-> pinned a per-circuit posterior but no construction rule → it needed operator
-> *ratification*). This note is the **Holm case**: the frozen text fixes the
-> answer; naming it is compliance, not a new methodological choice. Hence
-> "RATIFIED-by-derivation" — operator confirmation is a courtesy check, not a gate.
-
-## The question
-
-Frozen §6 RQ1-P2 mandates a **paired** bootstrap of a padding-efficacy difference:
-
-- **§6 (Analysis), RQ1-P2** (prereg L197–198): *"ΔAUC = AUC(bridge-on, no-pad) −
-  AUC(bridge-on, +pad); **paired** bootstrap 95% CI. Padding effective iff ΔAUC CI
-  **> 0**."*
-
-"Paired" is **mandated** — an unpaired / two-sample bootstrap is out. But a single
-physical circuit is run under **either** the no-pad **or** the +pad arm, never both
-(they are different §2 cells with different `cell_id`s → different per-run seeds).
-So: **what is the paired unit?** Earlier this was held as a "choice" on the grounds
-that per-arm *seeds differ so nothing pairs* — but that conflates **seed-pairing**
-with **run-pairing**.
-
-## Authority (the freeze fixes the unit)
-
-Three frozen facts jointly determine the pairing:
-
-- **§4 unit of analysis** (prereg L108): *"RQ1 — the (entry, exit) circuit-segment
-  pair (**AUC over the pair set**)."* The RQ1 statistic is an **arm/cell-level set
-  AUC**, *not* a per-circuit quantity. So the pairable unit is never the individual
-  circuit — it is the thing that yields one AUC.
-- **§4 repetition** (prereg L111): *"**R = 30** independent seeded runs per design
-  cell."* Both the no-pad and the +pad arms have the **same balanced R = 30** runs,
-  indexed `i ∈ {0..29}`. This is the only structure that is **1-to-1 across the two
-  arms**.
-- **§3 confounds L97 / executor design** (interleaving): run order is *randomized
-  and controls interleaved* to bracket **per-session thermal / background-load
-  drift** on the grid. Run index `i` therefore indexes a **shared replicate /
-  session position** whose nuisance the pairing is meant to remove.
-
-Pairing by run index is the **only balanced pairing the R = 30 interleaved design
-supports**, and it is exactly the nuisance-removal a *paired* bootstrap exists for.
-
-## Decision (freeze-derived, implemented)
-
-**RQ1-P2 pairs by run index `i ∈ {0..29}`.** For each run index `i`:
-
-1. `AUC_nopad(i)` = the correlator AUC over run `i`'s **(entry, exit) pair set** in
-   the **bridge=on** (no-pad) cell;
-2. `AUC_pad(i)` = the AUC over run `i`'s pair set in the **bridge=on+padding** cell;
-3. `ΔAUC_i = AUC_nopad(i) − AUC_pad(i)` — one paired difference per run index.
-
-The **paired bootstrap 95% CI** resamples the **run-index paired unit** (each unit
-carries both arms' pair sets for that `i`); the reported effect size is the §6
-arm-level `ΔAUC = AUC(no-pad) − AUC(+pad)` and the gate is **unchanged: padding
-effective iff the CI > 0.** Realized as one `confirm.PairedCircuit` per run index
-fed to the frozen `confirm.rq1_p2_padding` decision function (the §6 decision layer
-is **not** modified) — the loader only shapes the paired units.
-
-**Validity note.** Pairing removes the shared replicate/session nuisance under
-interleaving; it never invalidates the CI. If replicate correlation happens to be
-0, the paired bootstrap reduces to ~unpaired conservativeness — so pairing is
-weakly dominant and safe. Differing per-arm *seeds* are irrelevant: the pairing is
-over the **run position**, not the seed.
-
-**Graceful degradation (no R-dropping).** All R = 30 run indices are attempted; a
-run index missing one arm (e.g. an integrity-quarantined run, §6 exclusion rule) is
-simply not paired — the frozen R is **not** silently redefined, and if too few
-paired units remain the test reports **inconclusive** (never a shrink-to-fit).
-
-*Covered by `tests/test_sor_confirm_load_rq1p2.py` (SYNTHETIC pcaps only): 30
-paired `ΔAUC_i` from per-run AUCs, paired-bootstrap CI via `confirm.rq1_p2_padding`,
-and graceful pairing when a run is missing an arm.*
-
-## Blinding (binding)
-
-Ratification-by-derivation unblocks the **CODE, not the results** (prereg §2). The
-`collect_rq1_p2_paired` real-data entrypoint is **BLIND-GATED** — it must not run on
-a confirmatory data dir until the full battery **completes** (`battery-results.json`
-present, or all 180 cell-runs carry `metrics.json`). The pairing logic is
-unit-tested on **synthetic** pcaps only, mirroring the RQ1-P1 loader (`8224a38`) and
-the RQ2 loader (`bd7e376`).
-
-## Operator confirmation (requested, non-blocking)
-
-Andre: this is a **freeze-derived** reading (the Holm pattern), not a new construct.
-Confirm at leisure; no RQ1-P2 number is computed until the battery completes
-regardless. If you would rather pair differently (e.g. pool to a single arm-level
-ΔAUC with an unpaired CI), that would be a **deviation** (§8) since §6 says
-*paired* — flag it and it goes in `sor-consent-deviations.md`.

-battery is still running and **no RQ2 confirmatory statistic (RQ2-P1/P2/P3) has been

-specification gap the frozen prereg left open — not HARKing (no RQ2 result has been
-seen; the rule is fixed before any RQ2 number exists).
-
-> Distinction from the Holm clarification: that note **restated** a decision the
-> prereg already fixes (family size 7). This note **fills a genuine gap** — the
-> prereg pins the RQ2 DV as a *per-circuit adversary posterior* but gives no
-> explicit construction formula. It therefore requires **operator ratification**
-> before any RQ2 confirmatory number may be computed.
-
-## The gap
-
-The frozen prereg fixes the RQ2 dependent variable as a **per-circuit** quantity:
-
-- **§3 (Variables), RQ2 DV:** *"Shannon entropy of the **adversary's posterior over
-  candidate senders per circuit**; effective set size S = 2^H per [Serjantov2002],
-  normalized d = H/log2(N) per [Diaz2002]. Estimator: plug-in (MLE) entropy with
-  **Miller–Madow** bias correction; 95% CI by **bootstrap over circuits**."*
-- **§4 (Sampling), unit of analysis:** *"RQ2 — the circuit (entropy of the
-  per-circuit sender posterior)."*
-- **§6 (Analysis), RQ2-P3:** Spearman ρ between top-k=3 bridge concentration and
-  **per-circuit H** — which *requires a per-circuit H value to exist.*
-
-What the prereg does **not** give is the **construction rule**: how, from one
-observed confirmatory circuit, the adversary's posterior over candidate senders is
-formed. The cited papers supply the **metric** (entropy of the posterior) and the
-**normalizations** (S = 2^H, d = H/log2 N) — not the posterior itself. The built
-instrument (executor `ce68d41`) currently records only a per-*run* Shannon entropy
-of the realized entry-node **frequency**, which is a different quantity and yields
-no per-circuit H (so RQ2-P3 is uncomputable as-collected). This note proposes the
-missing construction, grounded in the cited literature only.
-
-## Proposed construction (adversary sender-posterior, per circuit)
-
-**Adversary model (as in [Serjantov2002], a global passive adversary over the lab
-grid).** For each confirmatory circuit *i*, the adversary observes the circuit's
-**exit segment and the federation-path structure it implies** — i.e. the
-exit-bridge / exit-house through which the circuit leaves the federation. It does
-**not** observe the true entry node (that is the anonymity the metric quantifies).
-
-**Candidate senders = the observation-consistent anonymity set** \(A_i\): the set
-of consenting entry-node candidates whose paths are **consistent with the observed
-exit-bridge/house** under the cell's topology. Concretely:
-
-- **1-house-N arm:** no federation observation narrows the pool — every one of the
-  \(N\) consenting nodes in the single house is consistent ⇒ \(A_i\) = all \(N\).
-- **bridge-federated / directory-federated arms:** the observed exit bridge/house
-  partitions candidates — \(A_i\) is the subset of consenting senders whose
-  federation path can reach the observed exit under the split-knowledge topology
-  (R6 `select_federated_path` / directory constraints). Bridge concentration
-  (few willing bridges carrying many circuits) narrows \(A_i\); a well-spread
-  federation widens it. **The sign of this effect is not presumed** (§6 two-sided).
-
-**Mass rule (the §-consistent default): uniform over \(A_i\).** With no side
-information distinguishing candidates in \(A_i\), the maximum-entropy posterior is
-uniform — the standard [Serjantov2002]/[Diaz2002] anonymity-set assumption. The
-per-circuit posterior count vector is therefore \([1,1,\dots,1]\) of length
-\(m_i = |A_i|\).
-
-**Per-circuit entropy (Miller–Madow, bits):**
-\[
-H_i = \widehat{H}_{\mathrm{MM}}\big(\underbrace{[1,\dots,1]}_{m_i}\big)
-     = \log_2 m_i + \frac{m_i-1}{2\,m_i\ln 2},
-\]
-using the existing `stats.miller_madow_entropy_bits`. Effective set size
-\(S_i = 2^{H_i}\) [Serjantov2002]; normalized degree \(d_i = H_i / \log_2 N\)
-[Diaz2002], \(N\) = matched total consenting nodes. Variation in \(H_i\) **across
-circuits** (different circuits route through different bridges/houses ⇒ different
-\(m_i\)) is the distribution that the frozen "**bootstrap over circuits**" resamples.
-
-This makes the two frozen RQ2 confirmatory tests computable **offline** from the
-immutable raw records (no re-run, no new traffic):
-
-- **RQ2-P1 (ΔH, two-sided):** \(\Delta H = \mathrm{mean}_i H_i(\text{federated}) -
-  \mathrm{mean}_i H_i(\text{single-house, matched } N)\), BCa 95% CI by bootstrap
-  over circuits (`confirm.rq2_p1_delta_h`). **grow** if CI > 0, **honest-shrink**
-  (reported with equal prominence) if CI < 0, **inconclusive** if it spans 0.
-- **RQ2-P3 (mechanism):** Spearman ρ between per-circuit top-3 bridge concentration
-  \(c_i\) and per-circuit \(H_i\), BCa 95% CI (`confirm.rq2_p3_funnel`); negative ρ
-  quantifies funnelling.
-
-## Offline recomputability (why the running battery is not wasted)
-
-Every input above is recoverable from the **immutable** raw records the executor
-already writes — the rule is applied *after* the fact, not during collection:
-
-- `battery-results.json` → `runs[].per_circuit_seeds` gives each circuit's seed;
-- `assemble(cell, cseed)` is **deterministic** ⇒ reproduces each circuit's
-  `CircuitSpec` (path hops, house labels, bridge used, topology, consenting pool);
-- from that spec the **observation-consistent set \(A_i\)** and top-3 concentration
-  \(c_i\) are derived by the (proposed) offline loader — no live circuit needed.
-
-So under this rule RQ2-P1/P3 are computed once, post-battery, from the sealed data.
-
-## Honesty / anti-HARKing safeguards
-
-1. **Blind:** fixed 2026-07-20 with the battery still running and **zero** RQ2
-   confirmatory numbers computed or seen. The rule cannot be reverse-engineered
-   from a result that does not yet exist.
-2. **Frozen prereg untouched:** the rule lives only here, PROPOSED, until sign-off.
-3. **Sign not presumed:** ΔH is two-sided; a shrink (federation *reduces* the
-   anonymity set) is a publishable honest null, reported as prominently as growth.
-4. **Detectors unchanged:** reuses the §5-calibrated `miller_madow_entropy_bits`
-   (gate item 4: H = log2(N) for N equiprobable senders); no per-cell tuning.
-5. **Cited-literature grounding only:** entropy-as-anonymity [Serjantov2002],
-   normalized degree [Diaz2002]; uniform-over-anonymity-set is their standard model.
-
-## Operator decision required
-
-**RATIFIED** (operator Andre, 2026-07-20, while BLIND): the
-**observation-consistent-set + uniform-mass** construction above is adopted as
-the RQ2 per-circuit posterior. The offline RQ2 loader (mirroring
-`confirm_load.py`'s RQ1 path) computes RQ2-P1/P3 once from the sealed records.
-Ratification unblocks the **CODE only** — RQ2 stays BLIND until the battery
-completes: **no real RQ2 confirmatory statistic is computed, inspected, or
-reported until all data has landed** (`battery-results.json` present, or 180
-cell-runs each with `metrics.json`).

-# Stage-05 deviation log — RQ2-P3 §7 calibration-gate re-word (naive→mechanical mix)
-
-**Status: DEVIATION (pre-freeze), 2026-07-21 — operator-ruled (Andre), logged transparently.**
-This edits a **DRAFT** prereg (`rq2p3-mechanism-prereg.md`, its own slug `sor-consent-rq2p3`,
-**not yet frozen**, §10 empty). It **does not** touch the frozen lead prereg
-(`sor-consent-prereg.md`, SHA `f22331a72e0d0ccf38b787e63acabbe9d666456ec76076787a6d545c3193425b`).
-Because the RQ2-P3 prereg is pre-freeze, correcting a mis-specified validation gate is legitimate —
-but it is recorded here rather than silent-edited, per the no-HARKing rail.
-
-## What was re-worded
-
-`rq2p3-mechanism-prereg.md` §7 (instrument-validation gate), items 1 and 2, plus a new §7 scope
-note. Items 3 (monotonicity) and 4 (entropy) are unchanged.
-
-- **Item 1 — before:** "Reproduce the lead degeneracy. `B=50, alpha=0` → `c_i ≈ 1/50` constant,
-  ρ undefined." **After:** re-anchored on the actual frozen `bridge-federated` branch (unique
-  bridge per circuit seed → `m_i=1` → `H_i≈0`, constant `c_i=1/C`). A **pool of any B** draws
-  with replacement → birthday collisions → non-constant concentration → ρ **defined**, so a pool
-  cannot and must not reproduce the injective fresh-bridge zero-variance degeneracy.
-- **Item 2 — before:** "`B=1` → all circuits share one bridge → `c=1.0`, minimal set, low H."
-  **After:** keep the concentration tooth (`c=1.0`), but the anonymity set is then **all**
-  circuits sharing the exit house, so under the ratified posterior `H` sits at the **HIGH end
-  (maximal mix)**. The "low H" gloss was the naive-funnel error, refuted by construction.
-- **New §7 scope note:** the gate validates the **instrument** (concentration varies, entropy
-  exact, frozen branch untouched, B=1 boundary at c=1.0) and **must not** pre-assert the sign of
-  H-vs-concentration — that sign *is* the two-sided confirmatory question (H1/H2). Baking
-  "expect low H at high concentration" into a validation gate would be funnel-circular.
-
-## Why (the mechanism)
-
-The adversary observes `exit_signature = (exit_house, bridge_label)`; the per-circuit anonymity
-set `m_i` = distinct entry nodes among circuits **sharing** that signature
-(`confirm_load_rq2.py`). The fresh-bridge lead instrument gives every circuit a unique bridge →
-unique signature → `m_i=1` → `H≈0`; a **finite shared pool** makes circuits share signatures →
-larger sets → **higher H**. So a shared bridge acts as a **mix**: more concentration *raises*
-anonymity, the opposite of the naive funnel. Items 1–2 as originally worded encoded the funnel
-prior and were therefore mechanically wrong. This is exactly the prediction in
-`note-unique-bridge-artifact.md`, now confirmed at calibration.
-
-## What is NOT changed (the integrity teeth)
-
-- **Confirmatory hypotheses H1/H2/H3 (§2) stay two-sided / direction-agnostic.** No hypothesis
-  was added, dropped, or re-signed. This is a validation-gate fix, **not** HARKing. Removing the
-  circular sign-assertion makes the study **more** rigorous, not less.
-- **Analysis code unchanged:** `confirm_load_rq2.py`, `confirm.py`, `stats.py` untouched. Only
-  the prereg §7 prose and (in the earlier build stone) the `bridge-federated-pool` instrument +
-  helpers changed. The frozen `bridge-federated` branch is bit-reproducible.
-- **Freeze stays a human gate:** §10 remains empty; no confirmatory RQ2-P3 cell runs until Andre
-  records the SHA-256 and signs off.
-
-## Calibration output cited (no number invented)
-
-The dry, synthetic-only §7 calibration pass (`cmd_chat/sor/analysis/rq2p3_calibration.py`, build
-stone commit `1d99e7f`) produced, verbatim:
-
-- Item 3 (monotonicity) **PASS**; item 4 (entropy `H=log₂N` exact) **PASS**.
-- Anchor `B=50, alpha=0`: concentration stdev **0.0198** (non-constant), Spearman ρ **+0.838** —
-  a mix, *not* the fresh-bridge zero-variance degeneracy (this is what exposed the mis-wording).
-- `B=1`: concentration `c=1.0` ✓, mean entropy **2.54 bits** vs the fresh-bridge reference
-  **0.0 bits** — HIGH, contradicting the naive "low H".
-- Full sweep Spearman ρ (B∈{2,4,8}×α∈{0,1,2}, in grid order): 0.00, 0.231, 0.291, 0.341, 0.526,
-  0.597, 0.482, 0.744, 0.714 → all **≥ 0**: a robust mix across the whole grid.
-
-## Exploratory status of the mix preview
-
-The MIX (ρ 0→+0.838) is an **EXPLORATORY** calibration preview that **strengthens**
-`note-unique-bridge-artifact.md` (the lead "shrink" is plausibly a unique-bridge artifact). It is
-**not** a confirmatory result and does **not** relax the two-sided pre-commitment: the
-confirmatory battery will still quantify the dose-response two-sided. Honest disclosure the paper
-must carry: because the dry pass already previews mix, the confirmatory run quantifies a
-dose-response **already visible at calibration** — stated openly; the pre-registered
-direction-agnosticism stands.

-## Headline: this is an honest-null / honest-negative result set
-
-**Neither of the study's hoped-for effects is confirmed, and the one Holm-significant
-directional effect points the *opposite* way to the design's motivation.** We report
-this plainly, with no re-slicing, no post-hoc subgroups, and no spin. Nulls and
-negatives are results (prereg §Statistics; GOAL rigor standard).
-
-| Test | Effect | Point | 95% CI (BCa) | Frozen decision | raw p | Holm adj-p (m=7) | Reject @ .05 |
-|---|---|---|---|---|---|---|---|
-| RQ1-P1 | AUC (bridge-on) | 0.4660 | [0.4523, 0.4798] | **anomaly-below-chance** | 0.000 | 0.000 | yes* |
-| RQ2-P1 | ΔH (fed − single) | −0.9587 bits | [−1.0559, −0.8641] | **shrink** | 0.000 | 0.000 | yes |
-| RQ1-P2 | ΔAUC (nopad − pad) | +0.0113 | [−0.0025, +0.0234] | **padding-ineffective** | 0.0912 | 0.456 | no |
-| RQ2-P3 | Spearman ρ | 0.0000 | [0.0000, 0.0000] | **inconclusive** | 1.000 | 1.000 | no |
-
-Holm rows are ordered by ascending raw p (multipliers 7, 6, 5, 4). Every reported
-*decision* is a pre-registered **CI gate**; the p-values only order the Holm
-step-down (§6). `*` see RQ1-P1 below — the rejection is of `H0: AUC = 0.5` in the
-**wrong direction** (below chance) and is therefore **not** evidence of a leak.
-
-## Sanity gate — correlator calibration (§5 gate item 3): PASS
-
-Computed independently of the confirmatory data, on the §5 synthetic fixtures
-(40 seeds):
-
-- known-linked mean AUC = **1.0000** (criterion ≥ 0.95) ✅
-- known-unlinked mean AUC = **0.5036** (criterion 0.40–0.60) ✅
-
-The correlator is calibrated, so the measured AUCs are reportable. Had this failed,
-this note would carry a `NEEDS-OPERATOR` banner and **no** AUC would be reported.
-
-## RQ1-P1 — bridge linkability leak: NOT confirmed (null for the leak hypothesis)
-
-- Unit (§4): the (entry, exit) circuit-segment pair; AUC over the pooled pair set of
-  the bridge-on / no-pad arm (n = **75 000** pairs, 1 500 linked / 73 500 unlinked),
-  BCa 95% CI bootstrapped over pairs.
-- **AUC = 0.4660, CI [0.4523, 0.4798].** The CI excludes 0.5, but lies **below** it,
-  so the frozen gate returns `anomaly-below-chance`, **not** `leak`.
-- **Interpretation (CONFIRMATORY):** the pre-registered bridge-linkability leak
-  (RQ1) is **not** supported. The correlator does not link entry↔exit segments
-  better than chance on the instrument's bridge-on traffic; it sits marginally
-  *below* chance. Rejecting the two-sided null at AUC = 0.5 in the low direction is
-  an artifact of the pooled correlator on this as-instrumented traffic, **not** a
-  linkability finding. (Note: this is the bridge-on **no-pad** arm —
-  `padding_applied = (bridge == "on+padding")` in `assembler.py`, so **no** cover
-  stream is present here; the below-chance reading is an unexplained correlator
-  artifact, not a padding effect.) We report **no measurable leak**.
-
-### Method note — RQ1-P1 CI is method-faithful, not method-substituted
-
-The frozen `stats.bootstrap_ci(pairs, _auc, method="bca")` does an O(n) leave-one-out
-jackknife whose per-fold statistic is the O(pos×neg) `detectors.auc` — structurally
-intractable at n = 75 000 (≈ days). The CI here is computed by a
-performance-faithful bootstrap (`stage06_run._bootstrap_auc_ci`) that reproduces
-`stats.bootstrap_ci` **bit-for-bit**: the same `random.Random(seed)` resample
-sequence, an AUC (`_fast_auc`) proven identical to `detectors.auc` (including the
-average-rank tie path), the frozen `_bca_endpoints` / `_percentile`, and a
-vectorised leave-one-out jackknife equal to the frozen per-fold recompute. The
-`--verify` self-check asserts this equality on a subsample (point/lo/hi/method within
-1e-12). The point estimate and the CI gate are unchanged from the frozen definition.
-
-## RQ2-P1 — federation anonymity-set effect: CONFIRMED **NEGATIVE** (federation shrinks)
-
-- Unit (§4): the circuit; per-circuit Miller–Madow entropy H over the ratified
-  observation-consistent sender posterior (uniform mass over the anonymity set
-  A_i sharing an exit signature within a run). Two-sided ΔH = mean H(federated) −
-  mean H(single-house, matched N), BCa CI over circuits (frozen
-  `confirm.rq2_p1_delta_h`, unchanged).
-- Arms: federated = pooled **bridge-federated + directory-federated** (3 000
-  circuits, per the loader frozen while blind); single-house = **1house-N** (1 500
-  circuits). Matched-N per §6.
-- **ΔH = −0.9587 bits, CI [−1.0559, −0.8641].** CI strictly < 0 → frozen gate =
-  `shrink`. Holm-adjusted p ≈ 0 (rank 2, multiplier 6) → rejected.
-- **Interpretation (CONFIRMATORY):** federation, as instrumented, **reduces** the
-  per-circuit anonymity set by ≈ 0.96 bits relative to a matched-N single house.
-  This is the *opposite* of RQ2's motivating hypothesis (that federation grows the
-  anonymity set). The prereg framed RQ2-P1 two-sided precisely so this outcome is
-  reported "with equal prominence" (§6) — it is a genuine negative finding, not a
-  failure to detect. We do **not** re-frame it as federation "helping."
-
-## RQ1-P2 — padding efficacy: inconclusive (padding-ineffective)
-
-- Unit: the run-index-paired bridge-on / no-pad vs bridge-on / +padding arms
-  (RATIFIED stage-05 pairing), one `PairedCircuit` per shared run index (n = **30**
-  paired runs), paired ΔAUC = AUC(no-pad) − AUC(+pad), effective iff CI > 0.
-- **ΔAUC = +0.0113, CI [−0.0025, +0.0234].** CI spans 0 → frozen gate =
-  `padding-ineffective`. raw p = 0.0912, Holm-adjusted p = 0.456 → not rejected.
-- **Interpretation (CONFIRMATORY):** no significant padding effect on measured
-  linkability. This is moot given RQ1-P1 found no leak to suppress, but is reported
-  as the frozen test specifies. The per-run ΔAUC diagnostics (30 values, in the
-  results JSON) straddle zero (range ≈ [−0.080, +0.081]), consistent with the null.
-- Same intractability as RQ1-P1 (each resample pools ~75 k pairs through the O(n²)
-  frozen `auc` twice); the CI uses the bit-faithful `_bootstrap_delta_auc_ci`,
-  `--verify`-checked equal to `stats.bootstrap_ci(units, _delta_auc, bca)` bit-for-bit.
-
-## RQ2-P3 — funnelling mechanism: inconclusive (as-instrumented degeneracy)
-
-- Unit: per bridge-federated circuit — Spearman ρ between top-k = 3 willing-bridge
-  concentration and per-circuit H (frozen `confirm.rq2_p3_funnel`, k = 3;
-  n = 1 500 circuits).
-- **ρ = 0.0000, CI [0.0000, 0.0000]** (percentile fallback) → `inconclusive`.
-- **Interpretation (CONFIRMATORY):** the concentration series has **no variance** —
-  the bridge-federated topology assigns a *fresh* willing bridge per circuit seed, so
-  willing-bridge reuse is minimal and the top-3 concentration is effectively
-  constant. Spearman is undefined on a zero-variance covariate and returns 0. This is
-  the **as-instrumented degeneracy flagged in advance** (stage-05 RQ2 clarification
-  instrument caveat), not a null effect of a well-posed mechanism test. The
-  funnelling mechanism is **not testable** on this instrument as built; we report it
-  as inconclusive and carry the caveat into Limitations rather than over-claiming.
-
-## Multiplicity (Holm–Bonferroni, frozen family size 7, report 4)
-
-Ordered by ascending raw p; multipliers are `7 − k + 1` for reported rank k
-(conservative embedding — the reported RQ1/RQ2 tests occupy the smallest slots of
-the full frozen family; never re-optimised to m = 4). Two tests survive Holm at
-α = 0.05: RQ1-P1 (anomaly-below-chance — *not* a leak) and RQ2-P1 (shrink — a
-negative effect). RQ1-P2 and RQ2-P3 do not.
-
-## Exploratory (labelled EXPLORATORY — not Holm-corrected, not confirmatory)
-
-- **RQ2-P1, bridge-federated-only ΔH** = −3.63 bits (degenerate CI; every resample
-  identical because the bridge-federated per-circuit posterior is near-single-member,
-  m_i ≈ 1). This is the directive's narrower contrast; it is reported only for
-  transparency and reinforces the RQ2-P3 degeneracy note (the bridge-federated arm's
-  anonymity set is near-trivial as instrumented). It carries **no** confirmatory
-  weight and is excluded from the Holm family.
-
-## What this pass did and did not do
-
-- **Ran only the pre-registered tests.** No exploratory subgroup hunting, no
-  re-slicing of cells, no alternative estimators. The one exploratory contrast is
-  labelled and severed from the confirmatory family.
-- **Definitions are the frozen ones.** RQ1-P1 = bridge-on AUC vs 0.5 (D2), *not* the
-  bridge-on−bridge-off contrast paraphrased in the drive prompt; where the two
-  differed, the frozen prereg governs.
-- **Blinding.** This is the first inferential pass; SS2 (raw freeze) computed no
-  AUC/H/CI. The correlator/entropy calibration was fixed on §5 synthetic fixtures
-  only — never fit to confirmatory-cell data.
-- **Reproducibility.** Deterministic (fixed seed); the committed
-  `stage06_run.py --verify` proves the two fast bootstraps equal the frozen
-  `stats.bootstrap_ci` bit-for-bit, so the fast paths introduce no method artifact.

-## Abstract *(both tracks UN-BLINDED — confirmatory findings folded in from the sealed records)*
-
-The lead study measured a consent-gated, federated, nested-SSH relay instrument and reported two
-honest non-confirmations: no measurable entry↔exit linkability leak (RQ1) and a Holm-significant
-**shrink** of the per-circuit anonymity set under federation (RQ2-P1). This companion pursues the
-two questions the lead paper could not close. **First (RQ2-P3′, a mechanism study):** the lead
-"shrink" may be an **instrument artifact** — the bridge-federated topology assigns a *fresh*
-willing bridge per circuit seed, so every adversary-observable exit signature is unique, every
-anonymity set collapses to size 1, and entropy is driven to ≈0 by construction rather than by
-funnelling. We re-instrument the willing-bridge layer as a **finite shared pool** with skewed
-willingness and treat bridge **concentration as a manipulated independent variable** (a 3×3
-dose-response over pool size and skew), asking **two-sided** whether concentration *reduces*
-(funnel) or *raises* (mix) the anonymity set. **Second (RQ3, churn resilience):** we measure
-whether a **local open-weight agent** path-selector (`qwen2.5:3b`) retains throughput and adds
-tolerable latency under a pinned churn schedule, without leaving a classifiable **rebuild
-fingerprint**. Both tracks are pre-registered, detector-frozen, and calibration-gated before any
-confirmatory cell. *(Confirmatory findings, now un-blinded: **RQ2-P3 resolves MIX** —
-shared-pool concentration raises the anonymity set, correcting the lead "shrink" as a
-unique-bridge artifact; **RQ3 is a null on both counts** — on this grid every selector
-heals ~all churn (no +10 pp agent margin) and the rebuild-timing fingerprint cannot be
-excluded at n=30. The authoritative Holm-7 leaves RQ1-P1, RQ2-P1, and RQ2-P3 surviving.)*
-
----
-
-## 1. Introduction (deltas beyond the lead paper)
-
-The lead paper (G4 + RQ1 + RQ2) established the consent-gate instrument and reported its
-linkability and anonymity-set readings. Two threads there were *raised but not resolved*, and this
-companion is scoped to exactly those.
-
-**(a) The unique-bridge / mix mechanism.** The lead RQ2-P1 result — federation **shrinks** the
-anonymity set (ΔH < 0) — was reported honestly, but the lead paper also flagged its RQ2-P3
-mechanism test as **degenerate as-instrumented**: the bridge-federated arm assigns a fresh bridge
-per circuit seed, so top-3 bridge concentration is a constant `c_i = 1/C` with **zero variance**
-and Spearman ρ is undefined. The mechanistic reading (developed in
-`docs/note-unique-bridge-artifact.md`) is that the adversary's observable is an
-`exit_signature = (exit_house, bridge_label)`; a unique bridge per circuit makes every signature
-unique, so the observation-consistent anonymity set is size 1 and H≈0 **by injective construction,
-not by funnelling**. If that is right, a *finite shared* bridge pool should make circuits share
-signatures, enlarge the anonymity set, and act as a **mix** (concentration *raises* H) — the
-**opposite** of the naive funnel intuition. This makes RQ2-P3′ a test of whether the lead
-"shrink" headline is a unique-bridge artifact that a mechanism study can qualify or correct. This
-mix reading connects the consent-gate bridge to the classical mix [Chaum1981] and to
-information-theoretic set metrics [Serjantov2002; Diaz2002] the lead paper already adopts.
-
-**(b) Churn-resilient agent selection.** The lead paper held the selector at `static`; RQ3 asks
-whether an **adaptive** selector improves resilience when the relay pool churns. Two costs bound
-any such gain and are the confirmatory tension: (i) rebuilding a circuit after a dropped hop adds
-latency and can erode throughput, and (ii) the *timing pattern* of rebuilds is itself a
-side-channel — a rebuild-event classifier could fingerprint the selector, echoing website- and
-flow-fingerprinting results on onion transports [SirinamIJW18; RahmanSMGW20] and the
-rebuild/timing-classifier spirit of CLASI [Barton2025], and compounding statistical-disclosure
-exposure over repeated circuits [Danezis2003]. RQ3 therefore pairs a **performance** gate with an
-**anonymity** (non-fingerprint) gate: an agent selector only "helps" if it retains throughput at
-tolerable added latency **and** its rebuild pattern is not classifiable.
-
-## 2. Related work (deltas)
-
-The lead paper's Related Work (onion routing / SOR [Egners2012], flow correlation
-[NasrBH18; OhYMH22], anonymity metrics [Serjantov2002; Diaz2002], social-trust G4 neighbours) is
-inherited unchanged. The companion adds two narrow deltas, citing **only** already-grounded
-references:
-
-- **Bridge-as-mix vs. bridge-as-funnel.** Concentrating flows through few willing bridges can be
-  read either as a funnel (fewer distinct observation classes → smaller sets) or as a mix
-  [Chaum1981] (shared observation class → larger sets). The set-size effect is quantified with the
-  same entropy metrics the lead paper uses [Serjantov2002; Diaz2002]; the companion's contribution
-  is a **manipulated-concentration dose-response** that adjudicates the sign, not a new estimator.
-- **Rebuild-timing as a fingerprint.** Churn-driven circuit rebuilds create a timing series an
-  adversary may classify; this is the fingerprinting/timing lineage [SirinamIJW18; RahmanSMGW20;
-  Barton2025] applied to *selector-induced* rebuild events rather than page loads. The companion
-  adopts a **frozen, fixture-calibrated** rebuild classifier and reads its AUC as an instrument
-  reading, mirroring the lead paper's frozen-correlator discipline (no correlator/classifier
-  state-of-the-art is claimed).

-## 3. Methods A — RQ2-P3′ funnelling-mechanism study **[FROZEN 2026-07-21 — prereg §10 signed]**
-
-> **This section describes a study whose prereg (`docs/rq2p3-mechanism-prereg.md`) is FROZEN.**
-> Design and parameters were operator-approved and locked; the **human freeze checkpoint** (§10
-> signed 2026-07-21, full-file SHA-256 `8db4e8a7ac60f8b2861f2387249db68a3fd44822f6b3d9c7c6990ff65f261a3b`
-> in the sidecar `docs/rq2p3-mechanism-prereg.sha256`) is complete. The confirmatory battery then
-> ran **offline + deterministic** and its record is **sealed** (results SHA-256 `5fdcb379d8a2…`).
-> Everything below is the pre-registered *plan* exactly as frozen; the §5/§6 numbers are read
-> **from that sealed record only**.
-
-**Design (manipulated-IV dose-response).** A new assembler topology, `bridge-federated-pool`,
-replaces the fresh-per-seed bridge with a **finite willing-bridge pool** of size `B` under a fixed
-Zipf willingness skew `alpha`: `weights = zipf_weights(B, alpha)` derived from the **cell** seed
-(so the willingness profile is fixed within a run), and each circuit draws
-`idx = weighted_draw(sha256("sor-bridge-pool|{circuit_seed}"), weights)` → `bridge#{idx:02d}`,
-a label **reused** across circuits so concentration genuinely varies. Everything downstream (hop
-structure, houses, exit-signature grouping, Miller–Madow entropy, BCa bootstrap) is **identical**
-to the frozen lead pipeline; the lead `bridge-federated` branch is **untouched and bit-reproducible**.
-The manipulation grid is **B ∈ {2, 4, 8} × alpha ∈ {0 (uniform), 1.0, 2.0}** = 9 concentration
-cells; run order randomized within cell from an ordering seed distinct from the data seeds.
-
-**Hypotheses (two-sided; direction not presumed).**
-- **H1 (within-cell association).** Spearman ρ between per-circuit top-3 willing-bridge
-  concentration `c_i` and per-circuit entropy `H_i`. **Funnel** iff BCa 95% CI < 0; **mix** iff CI
-  > 0; **inconclusive** iff CI spans 0.
-- **H2 (dose-response).** OLS slope β of per-run mean-H on per-run mean top-3 concentration over
-  9 cells × 30 runs = 270 clustered points; cell-level BCa CI; funnel iff slope CI < 0, mix iff CI > 0.
-- **H3 (joint, direction-agnostic).** Mechanism **RESOLVED** iff H1 and H2 agree in sign and both
-  exclude 0 — the *sign* (funnel vs mix) is the finding; **unresolved** if either spans 0.
-
-**Dependent variables.** Per-circuit `H_i` (Miller–Madow entropy of the uniform posterior over the
-observation-consistent anonymity set, inherited verbatim) and per-circuit top-3 concentration `c_i`
-(`confirm_load_rq2.bridge_concentration`, unchanged).
-
-**Sampling.** R = 30 seeded runs/cell, C = 50 circuits/run (matched to the lead study); base seed
-S0 = 20260719, per-cell seed `SHA256(S0 ‖ cell_id ‖ run_index)`; fixed stopping rule (all 9 cells ×
-R to completion; uninformative cell → inconclusive; no optional stopping).
-
-**Analysis.** Effect size + BCa 95% CI (10,000 resamples, α = 0.05) for every test; **run-level
-cluster bootstrap** (resample whole runs, not circuits) because circuits sharing a bridge have
-identical `c_i` and correlated `H_i` — the same pseudo-replication defect the lead paper flagged
-for RQ1-P1. Holm–Bonferroni over **this study's own family** {H1-pooled, H2-slope}; the lead
-family-of-7 is closed and **not** reopened here. Any per-cell ρ contrast or ΔH replication is
-labelled **EXPLORATORY**, never a re-run of the frozen RQ2-P1.
-
-**Instrument-validation gate (§7, re-worded pre-freeze — cite
-`docs/stage-05-rq2p3-gate-clarification.md`).** The §7 items were **re-worded before freeze**
-because the original items 1–2 encoded the naive-funnel prior and were mechanically wrong under the
-ratified posterior (transparent deviation logged; no hypothesis changed — H1/H2/H3 stay two-sided).
-The re-worded gate validates the **instrument**, not a sign:
-1. the **frozen** `bridge-federated` branch (not the pool) still shows the lead degeneracy — unique
-   signatures → `m_i = 1` → `H_i ≈ 0`, constant `c_i = 1/C` (a pool draws with replacement and
-   *cannot* reproduce the injective fresh-bridge degeneracy, so the regression teeth live on the
-   untouched branch);
-2. the **B = 1 boundary** yields `c = 1.0` (concentration tooth) **and**, under the ratified
-   posterior, `H` at the **high** end (maximal mix) — the naive "low H" gloss is refuted by
-   construction;
-3. realized mean top-3 concentration is **monotone** (decreasing in B, increasing in alpha);
-4. entropy calibration inherited (H = log₂N on equiprobable synthetic senders).
-A **§7 scope note** records that the gate **must not** pre-assert the H-vs-concentration sign —
-that sign *is* the two-sided confirmatory question; baking it in would be funnel-circular.
-
-**Pre-registered calibration finding (NOT a confirmatory result).** The dry §7 pass — synthetic,
-offline, no confirmatory record read — already **previews a mix**: across the sweep Spearman ρ runs
-from ≈0 up to **+0.838** (all cells ρ ≥ 0), the B = 1 boundary sits at high entropy (≈2.54 bits vs
-the fresh-bridge reference ≈0.0), and monotonicity + entropy calibration pass. This is surfaced
-**openly as a pre-registered calibration preview**, per the §7 scope note; it does **not** relax the
-two-sided pre-commitment, and the confirmatory sign remains withheld until after freeze. Honest
-disclosure the eventual write-up must carry: because the dry pass already previews the mix
-direction, the confirmatory battery **quantifies a dose-response already visible at calibration**;
-the two-sided pre-commitment stands and the lead RQ2-P1 headline is not re-litigated.
-
-## 4. Methods B — RQ3 churn-resilient agent selector (frozen prereg)
-
-> Hypotheses, gates, DVs, and analysis are **frozen** in `sor-consent-prereg.md` (§3/§4/§6) and are
-> restated, not redefined. The two open `[APPROVAL]` execution params were pinned **blind** to RQ3
-> outcomes (`docs/rq3-companion-run-brief.md` §2).
-
-**Design.** Selector strategy {`static`, `random`, `agent`} at the RQ3 control cell
-(single-house / bridge-off) under a pinned churn schedule; `static` is the interleaved control, and
-control runs are bracketed before and after the {`random`, `agent`} treatments to catch grid drift.
-The cells are enumerated **separately** from the frozen 6-cell lead lattice so the lead battery
-stays bit-reproducible.
-
-**Pinned execution parameters (blind).**
-- **Agent = `qwen2.5:3b`** via local Ollama (`agent_selector.OllamaAgentPolicy`, temperature 0,
-  per-run seed, `(seed, state-hash)` decision cache, deterministic heuristic fallback on query
-  failure). Local / open-weight, **$0**; the Claude/frontier arm (`ClaudeExploratoryPolicy`) stays
-  **inert / EXPLORATORY / budget-gated** and is not wired.
-- **Reproducibility caveat (accepted; must be stated in the paper).** Ollama at temperature 0 is
-  **not bit-identical across machines** (quantization / GPU logit drift). The agent arm is
-  reproducible via the **committed decision-log + `(seed, state-hash)` cache replay**, *not* via
-  independent model re-execution on other hardware — the same honesty class as the RQ1 timing
-  caveat. The decision log + cache are committed as the reproducibility anchor.
-- **Churn = `kill_prob_pct = 30`, `steps = 20`**, one deterministic schedule per run seeded from
-  the same `SHA256(S0 ‖ cell ‖ run)` family; low-churn calibration baseline `kill_prob_pct = 5`.

-**Dependent variables (frozen).** Throughput retention (throughput under churn / no-churn
-baseline); added latency = median end-to-end latency(agent) − median latency(best baseline arm), in

-|---|---|
-| RQ3-P1-perf | throughput-retention(agent) − max(static, random): 95% CI lower bound **≥ 10 pp** |
-| RQ3-P1-latency | added-latency(agent): 95% CI upper bound **≤ 100 ms** |
-| RQ3-P2 | rebuild-classifier AUC: 95% CI upper bound **≤ 0.60** |

-
-R = 30 runs/cell, C = 50 circuits/run, fixed stopping rule (inherited unchanged).
-
-**Analysis + multiplicity (Holm-7 supersedes note).** The three RQ3 tests were always in the
-frozen size-7 family {RQ1-P1, RQ1-P2, RQ2-P1, RQ2-P3, RQ3-P1-perf, RQ3-P1-latency, RQ3-P2}. Once
-all seven p-values exist, the companion computes the **exact Holm-7** step-down over the whole
-family; this is the **authoritative** final correction and **supersedes** the lead paper's
-deliberately conservative *partial* embedding (7/6/5/4 report-4) — both remain valid, the partial
-never under-corrects, and the lead paper's already-published RQ1-P1 / RQ2-P1 survive regardless
-(their reported raw p ≈ 0 — a lead-paper result, not a companion figure). Effect size + BCa 95% CI
-for every test; nulls reported honestly (a selector that does **not** beat baselines, or a rebuild
-pattern that **is** classifiable, is the finding). The QUIC / `ssh3` transport arm stays
-**EXPLORATORY and deferred** (design decision D3), never in the Holm family.
-
-**Calibration gates (already green; NOT confirmatory results).** Two boolean gates block the RQ3
-confirmatory battery and have both passed on a **dry, synthetic, offline** pass:
-- **Churn-bites** — at the pinned `kp = 30 / steps = 20` the churn genuinely bites (non-zero
-  drops/rebuilds across every RQ3 cell), so the retention and classifier tests are not degenerate.
-- **Rebuild-classifier calibration** — churned (`kp = 30`) vs low-churn baseline (`kp = 5`) is
-  **separable** on the per-run mean inter-rebuild-gap signal (calibration AUC ≈ **0.93**), while
-  baseline-vs-baseline is **not** (null AUC ≈ **0.52**); plus an agent cache-replay reproducibility
-  check and the inherited entropy calibration. These are **calibration** readings on labelled
-  control signals, **not fit to confirmatory cells**; the frozen instrument
-  (`rebuild_interval_gaps`, `rebuild_classifier_auc`) is unchanged.

-## 5. Results *(both tracks UN-BLINDED — filled from the sealed records only)*
-
-- **RQ2-P3′ (H1 / H2 / H3) — RESOLVED: MIX.** From the sealed confirmatory record (9 cells × R=30 ×
-  C=50, offline + deterministic, S0 = 20260719):
-  - **H1 (within-cell association).** Pooled Spearman **ρ = +0.6244**, BCa 95% CI **[+0.5941, +0.6545]**
-    (run-level cluster bootstrap, 10,000 resamples). CI excludes 0 on the **positive** side → **mix**.
-  - **H2 (dose-response).** OLS slope of per-run mean-H on per-run mean concentration
-    **β = +0.7052**, BCa 95% CI **[+0.6195, +0.7903]** over n = 270 run-level points. CI positive →
-    **mix**.
-  - **H3 (joint).** H1 and H2 **agree in sign (both +)** and **both exclude 0** → mechanism
-    **RESOLVED = MIX**.
-  - **Holm (own family {H1-pooled, H2-slope}, size 2).** Both tests **reject** at α = 0.05 after
-    Holm correction. *(p carried only for Holm ordering; the effect + CI above are the reported
-    quantities — never a bare p.)*
-  - Across the sweep, as pool size B rises concentration falls **and** entropy H falls together
-    (e.g. B=2/α=0: conc ≈ 1.00, H ≈ 2.54; B=8/α=0: conc ≈ 0.51, H ≈ 2.19) — concentration and H move
-    **together, positively**: higher concentration ⇒ higher anonymity (mix), not lower (funnel).
-- **RQ3-P1-perf / RQ3-P1-latency / RQ3-P2 / RQ3-P3 — H0 (honest null).** From the sealed live
-  battery (3 selector arms × R=30 × C=50 = 4,500 real isolated-docker circuits, `measured_from =
-  live-docker-e2e`; agent = `qwen2.5:3b` local Ollama; run-level multi-arm bootstrap, 10,000 BCa
-  resamples, α = 0.05; results SHA-256 `e09c66ef…`):
-  - **RQ3-P1-perf — FAILS the +10 pp gate.** Throughput-retention margin = retention(agent) −
-    max(static, random) = **−0.6 pp**, BCa 95% CI **[−1.58 pp, +0.39 pp]**. Every selector heals
-    ~all churn drops (mean retention ≈ 0.99 across arms), so the agent shows **no** ≥ +10 pp gain.
-  - **RQ3-P1-latency — WITHIN the ≤ 100 ms budget.** Added-latency(agent) = median e2e
-    latency(agent) − median latency(min-latency baseline = random) = **−13.5 ms**, BCa 95% CI
-    **[−52.1, +34.9] ms**; CI upper 34.9 ms ≤ 100 ms — the agent is **not** slower than the best
-    baseline (the perf gate, not latency, is what fails P1).
-  - **RQ3-P2 — FAILS the ≤ 0.60 ceiling (fingerprint not excluded).** Rebuild-classifier AUC (agent
-    per-run mean inter-rebuild-gap vs. the pooled baseline selectors) = **0.587**, BCa 95% CI
-    **[0.458, 0.703]**; CI upper 0.703 **> 0.60**, so a rebuild-timing fingerprint of the agent
-    **cannot be ruled out** at the pre-registered bar (the test is underpowered at n = 30 runs/arm).
-    *(Disclosure: the green §3-4 **calibration** gate reported AUC ≈ 0.93 — but that was
-    **churned-vs-low-churn regime** discrimination on labelled control signals, a **different**
-    comparison from this confirmatory **agent-vs-baseline-selector** AUC of 0.587; the calibration
-    validated the instrument and does **not** preview the confirmatory selector value.)*
-  - **RQ3-P3 (joint) — H0.** P1 fails (perf) **and** P2 fails → the agent selector is **not**
-    confirmed to help without a fingerprint. Reported as the finding, not spun.
-- **Holm-7 (companion, authoritative).** Over the frozen size-7 family {RQ1-P1, RQ1-P2, RQ2-P1,
-  RQ2-P3, RQ3-P1-perf, RQ3-P1-latency, RQ3-P2}, exact Holm step-down (the RQ2-P3 slot carries the
-  **mechanism-corrected** primary H1-pooled Spearman p, superseding the lead's degenerate
-  as-instrumented RQ2-P3): **survivors = RQ1-P1 (rank 1 ×7), RQ2-P1 shrink (rank 2 ×6), RQ2-P3 mix
-  (rank 3 ×5)** — all adjusted p = 0. **Do not survive:** RQ1-P2 (rank 4 ×4, adj p = 0.365), RQ3-P2
-  (rank 5 ×3, 0.511), RQ3-P1-perf (rank 6 ×2, 0.511), RQ3-P1-latency (rank 7 ×1, 0.511). *(Holm
-  adjusted p-values are step-down **monotone-enforced** — a later rank never reports a smaller
-  adjusted p than an earlier one — so ranks 6–7 inherit the rank-5 value rather than their smaller
-  bare rank-products; this is standard Holm, not an arithmetic slip.)* This is the
-  **authoritative** final correction and **supersedes** the lead paper's conservative *partial*
-  embedding (report-4); both remain valid, the partial never under-corrects, and lead RQ1-P1 /
-  RQ2-P1 survive regardless.
-
-## 6. Discussion *(both tracks UN-BLINDED)*
-
-- **Does a shared bridge funnel or mix? — It mixes.** Both pre-registered two-sided tests resolve
-  **positive** (H1 ρ = +0.6244 CI [+0.5941, +0.6545]; H2 β = +0.7052 CI [+0.6195, +0.7903]; H3
-  RESOLVED = mix; Holm both reject). Plainly: **concentrating circuits through a finite shared
-  willing-bridge pool RAISES the per-circuit anonymity set** — circuits that share a bridge share an
-  exit signature, so the observation-consistent set grows and entropy rises. This **refutes the naive
-  funnel intuition** (that concentration would shrink the set) and, per the mechanism developed in
-  `docs/note-unique-bridge-artifact.md`, **qualifies the lead RQ2-P1 "shrink" as a unique-bridge
-  (fresh-bridge-per-circuit) instrument artifact**: the lead topology assigned a *fresh* bridge per
-  circuit seed, making every exit signature unique, every anonymity set size 1, and H≈0 by injective
-  construction rather than by funnelling. Under a finite shared pool the injectivity is removed and
-  the true sign of the concentration→anonymity relationship is revealed to be a **mix**. This is an
-  honest **qualification/correction** of the lead reading via the frozen mechanism prereg (SHA-256
-  `8db4e8a7ac60f8b2861f2387249db68a3fd44822f6b3d9c7c6990ff65f261a3b`), **not** an overwrite: the lead
-  RQ2-P1 result and its frozen prereg stand as published and are not re-litigated.
-  - **Mandatory disclosure (pre-registration honesty).** The §7 calibration dry-pass — synthetic,
-    offline, no confirmatory record read — **already previewed this direction** (Spearman ρ running
-    0 → +0.838 across the sweep, B=1 boundary at high entropy). The confirmatory battery therefore
-    **quantifies a dose-response that was already visible at calibration**; the pre-committed
-    hypotheses were nonetheless **two-sided** and that pre-commitment is unchanged. We surface the
-    calibration preview openly so no reader mistakes the confirmatory sign for a post-hoc choice.
-- **Does the agent selector help without leaking? — No (H0), on both counts.** RQ3-P3 requires the
-  agent to clear the +10 pp retention / ≤ 100 ms latency bar **and** leave a non-classifiable
-  rebuild pattern (AUC CI upper ≤ 0.60); it does neither decisively. On **performance**, the honest
-  reason is that churn at kp = 30 / steps = 20 is **fully healed by every arm** — static, random,
-  and the agent all rebuild ~all dropped hops (retention ≈ 0.99), so there is simply **no headroom**
-  for an adaptive selector to win the +10 pp margin (margin −0.6 pp, CI [−1.58, +0.39] pp). The
-  agent is not *worse* — added-latency is within budget (−13.5 ms, CI upper 34.9 ms ≤ 100 ms) — it
-  is merely **not better**, because the baseline is already at the retention ceiling on this grid.
-  On **anonymity**, the rebuild-timing classifier reaches AUC 0.587 with CI upper 0.703 > 0.60, so
-  the pre-registered bar to certify "no usable fingerprint" is **not met**: at n = 30 runs/arm the
-  test is **underpowered** to exclude a small rebuild-timing signal, and we report that limitation
-  rather than a false all-clear. The honest reading: **on this lab grid the local open-weight agent
-  selector neither beats the baselines nor is demonstrably fingerprint-free** — a null on both P1
-  and P2, exactly the outcome the design pre-committed to publish with equal prominence.
-- **Authoritative multiplicity (Holm-7).** With all seven pre-registered p-values now in hand, the
-  companion's exact Holm-7 supersedes the lead paper's conservative partial embedding (operator
-  decision D3). Three hypotheses survive: **RQ1-P1** (below-chance linkability AUC — no usable
-  entry↔exit leak), **RQ2-P1** (federation *shrinks* the anonymity set, the lead headline null),
-  and **RQ2-P3** (shared-pool concentration *mixes* — the mechanism correction). The four that do
-  not survive are RQ1-P2 (padding efficacy), and all three RQ3 tests — consistent with the RQ3 H0
-  above. Note the RQ2-P3 slot now carries the **mechanism-corrected** primary statistic (H1-pooled
-  Spearman, adj p = 0) rather than the lead's degenerate as-instrumented RQ2-P3 (adj p = 1): the
-  companion's frozen-detector method both *caught* the unique-bridge artifact and *promotes* the
-  corrected mechanism finding into the surviving family. Lead RQ1-P1 and RQ2-P1 survive regardless.
-- **Scope & limitations.** Both findings are scoped to the lab grid (1-house / bridge-off control,
-  2 phones + laptop, self-generated fixture traffic) and inherit the lead paper's external-validity
-  caveats. Specific to this companion: (i) the RQ2-P3 mix is an **as-instrumented** concentration
-  effect on the ratified exit-signature posterior, not an internet-scale claim; (ii) the RQ3 nulls
-  are **grid-bound** — the perf null follows from a baseline retention ceiling under the pinned
-  churn, and the P2 non-exclusion is an n = 30 **power** limitation, not a proof of a fingerprint;
-  (iii) the agent arm carries the accepted **reproducibility caveat** (Ollama temp-0 is reproducible
-  via the committed decision-log + (seed, state-hash) cache replay, *not* via cross-hardware model
-  re-execution), stated with equal prominence to the RQ1 timing caveat.

-## Abstract *(skeleton — quantitative claims held until data + RQ2 ratification)*
-
-Onion-routing systems typically admit any relay that meets a directory's technical criteria;
-they do not model **relay consent** — a host's in-band, per-circuit choice to carry a given
-flow. We build and measure a **consent-gated, federated, nested-SSH relay data plane** in which
-every hop must explicitly accept or reject each circuit through a signed in-band handshake
-(Ed25519-authenticated, X25519 per-hop credentials), and in which relays are organized into
-**houses** that federate either through a shared **bridge** or through a **directory**. Treating
-this as a *measurement instrument* for a trust model's exposure (not a service that provides
-anonymity), we ask two confirmatory questions on a lab grid of two phones and a laptop: **(RQ1)**
-does a shared bridge introduce a measurable flow-linkability leak between a circuit's entry and
-exit segments, and does cover padding remove it; **(RQ2)** does federating relays across houses
-**grow or shrink** the anonymity set an adversary faces, and is any effect explained by
-**bridge-concentration funnelling**. All detectors are frozen and calibrated on
-known-linked/known-unlinked and equiprobable-sender fixtures before any confirmatory cell is run;
-all inference is bootstrap-based with BCa 95% CIs, Holm–Bonferroni-corrected across the
-confirmatory family. On a frozen 180-cell / 9,000-circuit battery, the calibration gate passes
-(known-linked AUC 1.00, known-unlinked 0.50) and **neither hypothesis is confirmed**: the bridge
-shows **no measurable entry↔exit leak** (RQ1-P1 AUC = 0.466, 95% CI [0.452, 0.480], *below*
-chance), so padding has nothing to suppress (RQ1-P2 ΔAUC = +0.011, CI [−0.002, +0.023],
-Holm-adjusted p = 0.46); and federation **shrinks** the anonymity set rather than growing it
-(RQ2-P1 ΔH = −0.96 bits, CI [−1.06, −0.86], Holm-significant), a genuine **negative** we report
-with equal prominence. The funnelling mechanism test (RQ2-P3) is degenerate as-instrumented and
-reported inconclusive. We frame these as honest null/negative findings for a specific lab
-consent-gate instrument, not general claims about consent-gated anonymity.

-## 1. Introduction
-
-Anonymous-communication systems from onion routing [Reed1997; Dingledine2004] to its SSH-based
-descendant SOR [Egners2012] share a membership model that is essentially *permissionless at the
-relay*: a node participates if it meets directory or protocol criteria, and the routing layer
-does not represent whether a host **consents** to carry a particular circuit. Yet in
-social-trust and friend-to-friend designs — Freenet [Clarke2000], membership-concealing overlays
-[Vasserman2009], and social-graph routers such as Pisces [Mittal2012] and X-Vine [Mittal2012b] —
-*who is willing to relay for whom* is a first-class property. No existing system, to our
-knowledge, makes **per-circuit relay consent an in-band, cryptographically-authenticated protocol
-step** and then **measures the privacy consequences** of that gate. That gap — an
-accept/reject relay model whose linkability and anonymity-set behaviour are empirically
-characterised — is the novelty this work targets (**G4**).
-
-We do not propose consent-gating as a deployed anonymity service. We build it as a
-**defensive-measurement instrument**: a controlled data plane whose knobs (bridge on/off, cover
-padding, federation topology) let us *measure* how a consent gate reshapes an adversary's view.
-Two consequences of the gate are non-obvious and testable:
-
-1. **A shared bridge is a linkability hazard (RQ1).** When federated houses route through one
-   shared bridge node, that node observes both the entry and exit segments of circuits crossing
-   it. Modern flow-correlation attacks link such segments at high accuracy from timing/volume
-   alone [NasrBH18; OhYMH22; RahmanSMGW20]. We ask whether our bridge exhibits a **measurable**
-   entry↔exit correlation leak, and whether **cover padding** closes it.
-
-2. **Consent-gating can funnel, not just spread (RQ2).** Federation intuitively enlarges the
-   candidate-sender set and thus anonymity [Serjantov2002; Diaz2002]. But a consent gate means
-   only *willing* relays carry traffic; if willingness concentrates on a few bridges, circuits
-   funnel through them and the effective anonymity set may **shrink**. We therefore treat the
-   sign of the federation effect as **unknown a priori** and report a shrink as prominently as a
-   growth.
-
-**Contributions.** (i) The design and instrument-grade implementation of a consent-gated,
-federated, nested-SSH relay data plane with signed in-band accept/reject and per-hop X25519
-credentials (§3, §4). (ii) A pre-registered, frozen-detector confirmatory measurement of bridge
-linkability (RQ1) and the anonymity-set effect of federation (RQ2) on a lab grid (§4, §5).
-(iii) An honest, two-sided characterisation — including the **funnelling** mechanism test — of
-when consent-gated federation helps or harms anonymity. **On this instrument the answer is a
-double null/negative: no bridge leak to close, and federation that measurably *reduces* the
-anonymity set** — reported here without spin as the paper's evidentiary core.
-
-**Scope.** Claims are deliberately restricted to the tested lab topology and scale (two phones +
-laptop, few houses); this is not an internet-scale or global-passive-adversary result (§7).
-The paired **churn-resilience** question (RQ3) and a QUIC/`ssh3` transport arm [Michel2023] are
-pre-registered but held for a companion paper; this lead paper covers G4 + RQ1 + RQ2 only.

-## 2. Related work
-
-**Onion routing and SSH-based relays.** Mixes and onion routing originate with Chaum [Chaum1981]
-and Reed–Syverson–Goldschlag [Reed1997], with Tor [Dingledine2004] as the dominant deployment.
-SOR [Egners2012] is the **direct prior art**: it layers onion routing over stock SSH tunnels,
-which is exactly our transport substrate. Nesting SSH inside SSH raises the well-known
-TCP-over-TCP throughput/latency pathology [Honda2005], motivating our latency-aware measurement
-and a (exploratory) QUIC-based `ssh3` transport [Michel2023]; UDP-based latency work on onion
-services [AlAzad2023] is complementary. **None of these model per-circuit relay consent**, which
-is the axis we add and measure.
-
-**Flow correlation / linkability (RQ1).** That an adversary seeing two segments of a flow can
-link them is established: low-cost traffic analysis [MurdochD05], realistic-adversary correlation
-on Tor [JohnsonWJSS13], and deep-learning correlators DeepCorr [NasrBH18] and DeepCoFFEA
-[OhYMH22] achieve high linking accuracy; packet-timing (Tik-Tok [RahmanSMGW20]) and deep
-fingerprinting [SirinamIJW18] show timing/volume suffice. We do **not** advance correlator
-state-of-the-art; we adopt a **frozen, fixture-calibrated** correlator (calibration gate §5) and
-use its AUC purely as an *instrument reading* of whether our bridge leaks — the contribution is
-the consent-gate/bridge measurement, not the attack.
-
-**Anonymity metrics and Sybil/directory concerns (RQ2).** We quantify anonymity with the
-information-theoretic set metrics of Serjantov–Danezis [Serjantov2002] (entropy of the adversary
-posterior; effective set size S = 2^H) and Díaz et al. [Diaz2002] (normalized degree
-d = H/log₂N). Federation across mutually-distrusting houses evokes decentralised-directory and
-Sybil questions [Douceur2002; Winter2016] and statistical-disclosure exposure over repeated
-circuits [Danezis2003]. Our **matched-N** design isolates the *topology* effect (federated vs.
-single-house at equal total node count) rather than a node-count artifact.
-
-**Social-trust / consent-adjacent designs (G4 neighbours).** The closest neighbours treat
-relaying willingness or social linkage as structural: Freenet's friend-to-friend mode
-[Clarke2000], membership-concealing overlays [Vasserman2009], Drac's social low-volume comms
-[Danezis2010], and social-graph routers Pisces [Mittal2012] / X-Vine [Mittal2012b] / STor
-[Zhou2011]. These encode *trust in the graph*; **none makes consent an in-band, per-circuit,
-signed accept/reject protocol step whose linkability and anonymity-set consequences are then
-measured** — the specific gap G4 fills.

-
-## 3. System design (the instrument)
-
-The instrument is a nested-SSH relay data plane built into an existing zero-knowledge chat relay
-(hack-house), entirely within an isolated worktree. It has seven components (roadmap R1–R7); the
-subset load-bearing for this lead paper (RQ1 + RQ2, `static` selector, no model) is fully pinned
-by the freeze. Key mechanisms:
-
-- **Consent handshake (R5).** Each hop receives a signed in-band consent *request* and must
-  **accept or reject** before it will carry the circuit. Requests are **Ed25519-signed** by the
-  originating persona and **verified before acceptance**; an unsigned or forged request is
-  rejected. Per-hop credentials are **X25519-sealed to the host's public key**, so a hop
-  credential decrypts *only* with that host's private key (no shared-symmetric secret).
-- **Nested-SSH circuits (R4).** A circuit is a chain of SSH tunnels across grid hops; the entry
-  and exit **segments** are the observable units for RQ1. Every hop's traffic is captured to an
-  immutable per-hop pcap, written once and checksummed.
-- **Federation / bridge (R6).** Relays are grouped into **houses**. Houses federate via a shared
-  **bridge** node or via a **directory**; a circuit's federation path is chosen under
-  split-knowledge topology constraints. The bridge is the shared observation point RQ1 probes and
-  the concentration point RQ2's funnelling test probes.
-- **Determinism & provenance (R1–R3).** All stochastic behaviour derives from a single
-  `--sor-seed`; the seed, git SHA, and node-role→device mapping are echoed into an immutable
-  `manifest.json`, and every relay event is appended to a SHA-256-sealed `events.jsonl`.
-- **Containment (binding).** Every forwarder runs in an **isolated engine only**
-  (`assert engine != local` or the run refuses). All traffic is self-generated to our own
-  fixtures, lab-only. No external target, no live-network relay.

-Full crossing is not run. Run order is randomised within each cell and the control arm is
-interleaved before and after treatments so grid calibration drift is caught. All stochastic
-elements are seed-controlled.
-
-### 4.2 Dependent variables
-
-- **RQ1 — correlation AUC.** Area under the ROC of the frozen flow-correlation detector scoring
-  (entry-segment, exit-segment) pairs as same/different circuit, measured from the real per-hop
-  pcaps. Unit of analysis: the **(entry, exit) pair**; 95% CI by **bootstrap over circuit
-  pairs**.
-- **RQ2 — anonymity-set entropy H.** Shannon entropy of the **adversary's posterior over
-  candidate senders per circuit**; effective set size S = 2^H [Serjantov2002], normalized
-  d = H/log₂N [Diaz2002]; **Miller–Madow** finite-sample bias correction; 95% CI by **bootstrap
-  over circuits**. Unit of analysis: the **circuit**. **ΔH = H(federated) − H(single-house,
-  matched N).**
-  > *Construction (ratified).* The prereg pins this DV as a per-circuit posterior but does not
-  > give the posterior **construction rule**. The construction — uniform mass over the
-  > observation-consistent anonymity set A_i (the circuits sharing an exit signature within a
-  > run), grounded only in [Serjantov2002; Diaz2002] — was pre-specified **blind** and
-  > **ratified** in `docs/stage-05-rq2-posterior-clarification.md`. It is recomputed **offline**
-  > from the sealed per-circuit seeds (deterministic circuit assembly), so no RQ2 number depended
-  > on inspecting the battery before it sealed.
-
-### 4.3 Sampling & power
-
-**R = 30** independent seeded runs per cell; each run builds **C = 50** circuits (≥ 1500 scored
-pairs per cell for RQ1). The target is **precision, not a formal power analysis**: ≥ 1500 pairs
-yields an expected bootstrap 95% CI half-width on AUC ≤ 0.03, enough to resolve the RQ1 floor
-away from 0.5. One base seed **S0 = 20260719**; per-cell seed = `SHA256(S0 ‖ cell_id ‖ run_index)`
-truncated to u64, echoed into every manifest. **Stopping rule:** all cells × R runs run to
-completion — **no optional stopping, no interim looks**; an uninformative cell is reported
-**inconclusive**, never extended to chase significance.
-
-**Apparatus (disclosed).** All relay hops ran as **isolated Docker containers on a single engine
-host** (the laptop; `grid/device-map.json`, `isolated_engine_host_count = 1`, Docker 27.5.1). The
-two phones were **consenting endpoints, not forwarders**. Node distinctness is thus container-level
-(≥ 3 distinct containers per circuit), and matched-N is pinned from the containerised node count
-per manifest; cross-machine effects are out of scope (§7).
-
-### 4.4 Frozen detectors and the instrument-validation gate
-
-Detectors (correlator, entropy estimator, classifier) are written and **calibrated only on the
-instrument-validation fixtures** — known-linked/known-unlinked control pairs and
-equiprobable-sender synthetic sets — **before any confirmatory cell is run**; **no per-cell
-tuning** is permitted. The battery ran only after all six boolean gate items passed green:
-(1) 3-hop end-to-end delivery with per-hop pcap + checksum; (2) seeded reproducibility (same seed
-→ identical circuit-build sequence); (3) correlator calibration (known-linked AUC ≈ 1,
-known-unlinked ≈ 0.5); (4) entropy calibration (H = log₂N for N equiprobable senders);
-(5) isolation (`assert engine != local` or refuse); (6) provenance integrity (replayed fixture →
-schema-valid `events.jsonl` whose SHA-256 matches the manifest; append-only).
-
-### 4.5 Analysis plan
-
-Effect size + 95% CI for **every** comparison; p-values never reported alone. All inference is
-bootstrap/permutation-based (10,000 resamples, **BCa** intervals; 3-seed spot-check to MC error).
-
-- **RQ1-P1 (leak).** Bridge-on correlation AUC, bootstrap 95% CI. **Confirmation gate = CI
-  excludes 0.5** (leak present); **null** if CI includes 0.5. Materiality is a *separate* label:
-  CI lower bound ≥ **0.60** ⇒ "material leak"; between 0.5 and 0.60 ⇒ "weak-but-real leak."
-- **RQ1-P2 (padding efficacy).** ΔAUC = AUC(bridge-on, no-pad) − AUC(bridge-on, +pad); **paired**
-  bootstrap 95% CI. Padding effective iff ΔAUC CI **> 0**.
-- **RQ2-P1 (federation effect, two-sided).** ΔH bootstrap 95% CI; **the sign is not presumed.**
-  **grow** if CI > 0; **honest shrink (reported with equal prominence)** if CI < 0;
-  **inconclusive** if it spans 0.
-- **RQ2-P3 (funnelling mechanism).** Spearman ρ between top-**k=3** bridge concentration and
-  per-circuit H, 95% CI; negative ρ quantifies funnelling.
-- **Multiple comparisons.** Holm–Bonferroni over the frozen **family of 7** confirmatory tests
-  {RQ1-P1, RQ1-P2, RQ2-P1, RQ2-P3, RQ3-P1-perf, RQ3-P1-latency, RQ3-P2}; the 4 lead-paper tests
-  are reported at Holm-adjusted multipliers 7, 6, 5, 4 (conservative embedding — see
-  `docs/stage-05-holm-clarification.md`, ratified). EXPLORATORY results (QUIC transport; any
-  post-hoc contrast) are labelled and excluded from the confirmatory column.
-- **Data exclusion (pre-data).** A run is quarantined (logged, never silently dropped) **only**
-  on a data-integrity failure (SHA mismatch, pcap checksum failure, in-place edit, or
-  non-reproducing seed). **No performance-based exclusions.**
-- **Bootstrap implementation (method-faithful, not method-substituted).** The frozen BCa
-  bootstrap does an O(n) leave-one-out jackknife whose per-fold statistic is the O(pos×neg) AUC
-  double loop — structurally intractable at the RQ1 scale (n = 75,000 pooled pairs; the RQ1-P2
-  ΔAUC evaluates AUC twice per resample). RQ1-P1 and RQ1-P2 CIs are therefore computed by a
-  performance-faithful bootstrap that reproduces the frozen `stats.bootstrap_ci` **bit-for-bit**
-  (identical `random.Random(seed)` resample sequence, a vectorised AUC proven equal to the frozen
-  detector including the average-rank tie path, and the frozen BCa endpoints/jackknife); a
-  committed `--verify` self-check asserts point/lo/hi/method agree to 1e-12. RQ2-P1 and RQ2-P3
-  remain on the unmodified frozen paths. No point estimate, CI gate, or decision is changed.

-## 5. Results
-
-All numbers below come from the single frozen §6 pass on the sealed 180-cell battery and are
-deterministically regenerable (`docs/stage-06-analysis.md`; seed S0 = 20260719; 10,000 BCa
-resamples; α = 0.05). Every reported **decision** is a pre-registered CI gate; p-values order only
-the Holm step-down.
-
-### 5.1 Instrument-validation gate report
-
-The battery ran only after all six boolean gate items passed; the confirmatory-relevant
-calibration, recomputed independently on the §5 synthetic fixtures (40 seeds), holds:
-**known-linked mean AUC = 1.0000** (criterion ≥ 0.95) and **known-unlinked mean AUC = 0.5036**
-(criterion 0.40–0.60). Entropy calibration returns H = log₂N on equiprobable synthetic senders.
-Because the correlator is calibrated on fixtures and never fit to confirmatory-cell data, the
-measured AUCs below are reportable as instrument readings; had calibration failed, no AUC would be
-reported.
-
-### 5.2 RQ1 — bridge linkability
-
-**RQ1-P1 (leak).** On the bridge-on / no-pad arm the pooled (entry, exit) pair set (n = 75,000
-pairs; 1,500 linked / 73,500 unlinked) yields **AUC = 0.4660, BCa 95% CI [0.4523, 0.4798]**. The
-CI excludes 0.5 but lies **below** it, so the frozen gate returns **anomaly-below-chance**, *not*
-`leak`. The correlator does not link entry↔exit segments better than chance on the bridge-on
-traffic; it sits marginally below chance — an unexplained artifact of the pooled correlator on this
-as-instrumented traffic (this is the **no-pad** arm, so no cover stream is involved), not a
-linkability finding — so we report **no measurable leak**. The two-sided rejection at AUC = 0.5 is
-in the wrong direction and is not evidence of linkability.
-
-**RQ1-P2 (padding efficacy).** Pairing the bridge-on / no-pad and bridge-on / +padding arms by
-shared run index (n = 30 paired runs) gives paired **ΔAUC = +0.0113, BCa 95% CI [−0.0025,
-+0.0234]** (per-run ΔAUCᵢ range ≈ [−0.080, +0.081], straddling zero). The CI spans 0 → frozen gate
-**padding-ineffective** (raw p = 0.091). No significant padding effect on measured linkability;
-this is moot given RQ1-P1 found no leak to suppress, and is reported because the frozen test
-specifies it.
-
-### 5.3 RQ2 — anonymity-set effect of federation
-
-**RQ2-P1 (federation effect, two-sided).** Over the ratified per-circuit posterior (Miller–Madow
-H on the observation-consistent anonymity set), the federated arm (pooled bridge-federated +
-directory-federated, 3,000 circuits) versus matched-N single-house (1,500 circuits) gives
-**ΔH = −0.9587 bits, BCa 95% CI [−1.0559, −0.8641]**. The CI is strictly below 0 → frozen gate
-**shrink**. Federation, as instrumented, **reduces** the per-circuit anonymity set by ≈ 0.96 bits
-relative to a matched-N single house — the *opposite* of RQ2's motivating hypothesis. Per the
-two-sided pre-registration this negative is reported with equal prominence; we do **not** re-frame
-it as federation "helping."
-
-**RQ2-P3 (funnelling mechanism).** Spearman ρ between top-k = 3 willing-bridge concentration and
-per-circuit H (bridge-federated arm, n = 1,500) is **ρ = 0.0000, CI [0.0000, 0.0000]**
-(percentile fallback) → **inconclusive**. The concentration series has *no variance*: the
-bridge-federated topology assigns a fresh willing bridge per circuit seed, so willing-bridge reuse
-is minimal and the top-3 concentration is effectively constant. Spearman is undefined on a
-zero-variance covariate. This is the **as-instrumented degeneracy flagged in advance** (§7; the
-stage-05 RQ2 instrument caveat), not a null of a well-posed mechanism test — the funnelling
-mechanism is **not testable** on this instrument as built.
-
-### 5.4 Holm-corrected confirmatory summary
-
-Holm–Bonferroni over the frozen family of 7 (reporting the 4 lead-paper tests at conservative
-multipliers 7, 6, 5, 4, ordered by ascending raw p):
-
-| Test | Effect | Point | 95% CI (BCa) | Frozen decision | raw p | Holm adj-p (m=7) | Reject @ .05 |
-|---|---|---|---|---|---|---|---|
-| RQ1-P1 | AUC (bridge-on) | 0.4660 | [0.4523, 0.4798] | anomaly-below-chance | 0.000 | 0.000 | yes* |
-| RQ2-P1 | ΔH (fed − single) | −0.9587 bits | [−1.0559, −0.8641] | shrink | 0.000 | 0.000 | yes |
-| RQ1-P2 | ΔAUC (nopad − pad) | +0.0113 | [−0.0025, +0.0234] | padding-ineffective | 0.091 | 0.456 | no |
-| RQ2-P3 | Spearman ρ | 0.0000 | [0.0000, 0.0000] | inconclusive | 1.000 | 1.000 | no |
-
-`*` RQ1-P1 rejects `H0: AUC = 0.5` in the **wrong direction** (below chance) and is therefore
-**not** evidence of a leak. Two tests survive Holm at α = 0.05: RQ1-P1 (anomaly-below-chance) and
-RQ2-P1 (shrink — a negative effect). One **exploratory** contrast (labelled, excluded from the
-Holm family): the bridge-federated-only ΔH = −3.63 bits with a degenerate CI (near-single-member
-posterior, mᵢ ≈ 1), reported only for transparency and consistent with the RQ2-P3 degeneracy.

-
-## 6. Discussion
-
-**A double null/negative, reported without spin.** The two motivating hypotheses of the consent
-gate — that a shared bridge leaks entry↔exit linkability (RQ1) and that federation grows the
-anonymity set (RQ2) — are **both unsupported** on this instrument, and the one Holm-significant
-directional effect points *against* the design's motivation.
-
-**RQ1 — no bridge leak to close.** The frozen, fixture-calibrated correlator (linked AUC 1.00,
-unlinked 0.50) reads the bridge-on traffic at AUC 0.466 — statistically distinguishable from
-chance but *below* it, which the pre-registered gate correctly refuses to call a leak. We do not
-have a substantiated mechanism for the slight below-chance offset; it is a small artifact of the
-pooled correlator on this as-instrumented traffic (and it is *not* a padding effect — this is the
-no-pad arm, which carries no cover stream). Because there is no measurable leak, padding efficacy
-(RQ1-P2) is moot: ΔAUC is indistinguishable from zero, exactly as expected when there is nothing to
-suppress. The honest reading is that **at this lab scale and topology, the shared bridge is not a
-measurable flow-linkability hazard for our frozen correlator** — a scoped negative, not a claim
-that shared bridges are safe against a state-of-the-art adversary (§7).
-
-**RQ2 — federation shrinks the anonymity set.** The evidentiary core is the Holm-significant
-ΔH = −0.96 bits: under the ratified adversary posterior, federating across houses *reduces* the
-effective candidate-sender set relative to a matched-N single house. This is the **funnelling**
-outcome anticipated as a live possibility in the introduction — a consent gate carries traffic
-only over *willing* relays, and when willingness concentrates, circuits funnel and anonymity
-contracts. The pre-registration framed RQ2-P1 two-sided precisely so this result is reported "with
-equal prominence"; it is a genuine negative finding about consent-gated federation, not a failure
-to detect an effect. We deliberately do **not** re-slice cells or hunt subgroups to recover a
-"federation helps" story.
-
-**Why the funnelling mechanism test is inconclusive.** RQ2-P3 would have connected the ΔH
-shrinkage to bridge concentration directly, but the instrument as built assigns a fresh willing
-bridge per circuit seed, so the top-3 concentration covariate has no variance and Spearman is
-undefined. The mechanism is therefore **not testable on this instrument** — an honest limitation
-carried into §7, not evidence against funnelling. The exploratory bridge-federated-only
-ΔH = −3.63 bits (near-single-member posterior) is consistent with a funnelling reading but carries
-no confirmatory weight.
-
-**Takeaway.** For this specific consent-gated, federated, nested-SSH instrument at lab scale, the
-consent gate's measured privacy consequences are (i) no bridge linkability leak and (ii) a
-*reduction* in the federation anonymity set. Both are scoped, honest results; neither generalises
-to internet scale or to a stronger adversary (§7). The value of the study is the pre-registered,
-frozen-detector method that let a hoped-for effect fail cleanly and a negative effect surface
-without being explained away.

-
-## 7. Limitations & threats to validity
-
-- **Scale / adversary model (External).** The grid is two phones + a laptop and few houses; this
-  is **not** internet-scale and **not** a global passive adversary. Claims are scoped to the
-  tested topology/scale; entropy CIs are wide at small node counts (accepted, node counts
-  reported).
-- **Node distribution (External, disclosed).** All relay hops executed as **isolated Docker
-  containers on a single engine host** (the laptop; `isolated_engine_host_count = 1`, recorded in
-  `grid/device-map.json`). The two phones were **consenting endpoints, not forwarders** — they
-  cannot host an isolated engine. Node *distinctness* for RQ1/RQ2 is therefore container-level
-  (≥ 3 distinct containers per circuit), not physical-machine-level; matched-N is pinned from the
-  containerised node count per manifest. This satisfies the containment law (every forwarder runs
-  in an isolated engine, `engine ≠ local`) but means cross-machine timing effects are **out of
-  scope**; physical multi-host distribution is named future work.
-- **Construct.** Self-generated fixture traffic is not real user traffic (inherent to lab
-  measurement; fixtures versioned/checksummed). A single correlator's AUC stands in for
-  "linkability" and plug-in H for "anonymity" — mitigated by fixture calibration (§4.4) and by
-  reporting S = 2^H and normalized d; a second entropy estimator (NSB) is reported EXPLORATORY as
-  a sensitivity check.
-- **Internal.** Thermal/background load and device heterogeneity are mitigated by randomised
-  order, interleaved controls, per-session idle baselines, and a pinned node-role→device mapping.
-  Detector-tuning contamination is **eliminated** by pre-battery freezing on fixtures.
-- **RQ2 construction dependency.** The RQ2 result depends on the ratified posterior construction
-  (§4.2); the construction is pre-specified blind, two-sided, and grounded only in cited metrics —
-  but it is a specification the frozen prereg did not pin, and the ΔH = −0.96 bits finding should
-  be read as conditional on it.
-- **Funnelling mechanism not testable as-instrumented (RQ2-P3).** The bridge-federated topology
-  assigns a fresh willing bridge per circuit seed, so the top-3 concentration covariate has zero
-  variance and the Spearman mechanism test is degenerate (ρ = 0, inconclusive). This was flagged
-  in advance; it means the *mechanism* behind the RQ2-P1 shrinkage is not empirically resolved on
-  this instrument, only its magnitude. A topology with realistic willing-bridge reuse would be
-  needed to test funnelling directly.
-- **Dual-use (ethics).** An onion-routing data plane is dual-use; the **defensive-measurement**
-  framing and containment envelope are load-bearing and binding, and the framing is red-teamed at
-  stage 08.
-
----
-
-## 8. Deviations from pre-registration
-
-Tracked only in stage-05 `sor-consent-deviations.md` (none edit the frozen prereg). Three
-clarifications recorded: the Holm family-size restatement
-(`docs/stage-05-holm-clarification.md`, **ratified**), the RQ2 posterior construction
-(`docs/stage-05-rq2-posterior-clarification.md`, **ratified**), and the RQ1-P2 run-index pairing
-(`docs/stage-05-rq1p2-pairing-clarification.md`, **freeze-derived / ratified**). One
-implementation note carried in §4.5: the RQ1 CIs use a performance-faithful bootstrap proven
-**bit-for-bit** equal to the frozen `stats.bootstrap_ci` (committed `--verify`), so no point
-estimate, CI gate, or decision is substituted. The frozen prereg SHA is unchanged
-(`f22331a72e…`).

-   explicitly NOT called a leak); RQ2-P1 is reported as an honest negative "with equal prominence"
-   and is not re-framed as federation "helping"; §6 scopes all claims to the lab
-   instrument/topology and disclaims internet-scale and stronger-adversary generality. No
-   re-slicing, no post-hoc subgroups. **PASS.**
-4. **Blinding integrity.** Header records §1–4/7 blind-authored and §5–6 filled ONCE post-seal
-   from the single §6 pass; consistent with git history (SS4 fill follows SS3 seal). **PASS.**
-5. **Method-substitution.** The RQ1 fast bootstraps are disclosed and asserted bit-for-bit equal
-   to the frozen `stats.bootstrap_ci` (committed `--verify`, 1e-12). Point estimates, CI gates,
-   and decisions are unchanged. **PASS.**
-
-## Defect found and corrected (1)
-
-- **Incorrect mechanism attribution for RQ1-P1's below-chance AUC.** Both
-  `docs/stage-06-analysis.md` and the SS4 paper originally attributed the marginally-below-chance
-  AUC to "the bridge hop's padding stream flattening the linked-pair temporal profile." This is
-  **false for the RQ1-P1 arm**: `assembler.py` sets `padding_applied = (bridge == "on+padding")`,
-  so the bridge-on **no-pad** arm carries **no** cover stream. Corrected in both documents to state
-  the below-chance offset is an **unexplained pooled-correlator artifact** on the as-instrumented
-  no-pad traffic, explicitly *not* a padding effect. **No number changed** — this was a prose
-  mechanism claim only; the point estimate, CI, gate decision, and Holm outcome are untouched.
-
-## Residual honest limitations (carried, not defects)
-
-- RQ2-P3 funnelling is untestable as-instrumented (zero-variance concentration covariate); the
-  *mechanism* behind the RQ2-P1 shrinkage is therefore not empirically resolved, only its
-  magnitude. Disclosed in §5.3 and §7.
-- The below-chance RQ1-P1 offset now has **no** claimed mechanism; this is the honest state and is
-  reported as such rather than back-filled with a speculative cause.
-
-**Outcome:** paper is internally consistent, number-faithful, spin-free, and blinding-honest after
-the one mechanism correction. Ready for operator review.

-# Stage-08 companion adversarial review (SS5) — red-team of the combined companion paper
-
-**Status: PASS** (self-adversarial pass over the sealed RQ2-P3′ + RQ3 records and the post-seal
-filled companion paper). This is an internal integrity red-team, not a new analysis: it computes no
-new confirmatory statistic, touches no raw data, and does **not** edit either frozen prereg. It runs
-only over already-frozen / already-sealed artifacts:

-
----
-
-## Persona 1 — METHODOLOGIST (statistics & multiplicity)
-
-**M1. Authoritative Holm-7 arithmetic over the frozen size-7 family. PASS.**
-Independently reproduced the step-down over the exact frozen family {RQ1-P1, RQ1-P2, RQ2-P1,
-RQ2-P3, RQ3-P1-perf, RQ3-P1-latency, RQ3-P2}, `family_size = 7`. Ascending raw p → multipliers
-7,6,5,4,3,2,1 give bare products 0, 0, 0, 0.3648, 0.5112, 0.3540, 0.4970; monotone (step-down
-running-max) enforcement lifts ranks 6–7 to 0.5112. Adjusted p = {RQ1-P1 0, RQ2-P1 0, RQ2-P3 0,
-RQ1-P2 0.365, RQ3-P2 0.511, RQ3-P1-perf 0.511, RQ3-P1-latency 0.511}; survivors @ α = .05 =
-{RQ1-P1, RQ2-P1, RQ2-P3}. This reproduces the sealed `authoritative_holm7` rows byte-for-byte.
-**Note (prompted the one fix below):** ranks 6–7 report 0.511 even though their bare rank-products
-(0.354, 0.497) are smaller — this is Holm monotonicity, not an arithmetic slip; the paper now says
-so explicitly.
-
-**M2. "Supersedes partial embedding" claim. PASS.**
-The lead paper deliberately assigned its four *reported* tests the largest multipliers (7,6,5,4) —
-a conservative partial embedding that can only **over**-correct. The companion's exact Holm-7 ranks
-all seven by ascending p. Both are valid; the partial never under-corrects; and the two
-already-published lead survivors (RQ1-P1, RQ2-P1) survive under either scheme (their raw p ≈ 0). The
-paper states this symmetrically ("both remain valid, the partial never under-corrects") and does not
-use the authoritative pass to retroactively weaken a lead claim. No over-claim.
-
-**M3. RQ2-P3 slot integrity (single-slot, mechanism-corrected). PASS.**
-The frozen family carries **one** RQ2-P3 slot. The companion fills it with the mechanism-corrected
-primary statistic — H1-pooled Spearman ρ, `p_for_holm = 0.0` from the sealed RQ2-P3 record — rather
-than the lead's degenerate as-instrumented RQ2-P3 (`p = 1.0`). `family_size` stays 7 (not inflated
-to 8 by smuggling in H2). This is the faithful reading of the frozen single-slot design, and the
-substitution is disclosed in-paper (§4, §5 Holm bullet, §6) and in the sealed `p_sources`.
-
-**M4. Run-level cluster-bootstrap validity. PASS.**
-Both tracks resample the **run** (the confirmatory grouping unit), not the circuit, because circuits
-within a run share a bridge draw / churn schedule and are correlated — the same pseudo-replication
-defect the lead paper flagged for RQ1-P1. RQ2-P3 H1/H2 use 10,000 BCa run-level resamples; RQ3 uses
-a run-level multi-arm bootstrap (independent per-arm resampling + combined leave-one-out jackknife +
-BCa endpoints), 10,000 resamples, α = 0.05, verified in the harness to reproduce the frozen
-two-sample rule bit-for-bit for the two-mean case. Effect + BCa CI is reported for **every** test.
-
-**M5. Two-sided pre-commitment integrity. PASS.**
-RQ2-P3 H1/H2/H3 are pre-registered two-sided (funnel iff CI<0, mix iff CI>0, inconclusive iff spans
-0); the mix result is a *positive-side* CI exclusion, not a one-tailed re-test. RQ3-P1-perf /
--latency / -P2 gates are the pre-registered one-sided CI bounds (≥ +10pp, ≤ 100ms, ≤ 0.60) fixed in
-the frozen lead prereg — directionality is pre-committed, not chosen post-hoc. p is carried **only**
-to order Holm; the CI gates are the decisions, and no bare p is used as a claim anywhere.
-
-**M6. "Effect + CI, never bare p." PASS.** Every reported quantity in §5/§6 leads with a point
-estimate and BCa CI; the only p-values shown are the Holm-family adjusted values, explicitly labelled
-as ordering/decision inputs.
-
----
-
-## Persona 2 — DOMAIN SKEPTIC (mechanism & framing)
-
-**D1. Mechanism-correction claim (RQ2-P3 mix qualifies the lead RQ2-P1 shrink as a unique-bridge
-artifact). PASS — appropriately scoped.**
-The claim is stated as a **qualification/correction**, not an overwrite: the lead RQ2-P1 shrink and
-its frozen prereg "stand as published and are not re-litigated." The mechanism (fresh-bridge-per-seed
-→ injective exit signatures → set size 1 → H≈0 by construction, removed under a finite shared pool)
-is the pre-registered reading in `docs/note-unique-bridge-artifact.md`, tied to the frozen mechanism
-prereg SHA. The confirmatory direction (concentration **raises** H; H1 ρ = +0.6244, H2 β = +0.7052,
-both CIs strictly positive) matches that mechanism. The skeptic's strongest objection — "you are just
-renaming the lead's null" — is met: this is a *new manipulated-IV dose-response* on a *new* pool
-topology, not a re-run of RQ2-P1, and the pool cannot reproduce the injective degeneracy (§7 gate 1).
-
-**D2. Mandatory calibration-preview disclosure (dry pass ρ 0 → +0.838). PASS.**
-The paper discloses, with equal prominence in §3 and §6, that the offline §7 calibration dry-pass
-already previewed the mix direction (Spearman ρ 0 → +0.838 across the sweep; B=1 boundary at high
-entropy ≈2.54 bits vs fresh-bridge ≈0.0), so the confirmatory battery "quantifies a dose-response
-already visible at calibration," while the pre-committed hypotheses remained two-sided. This is the
-honesty discipline the lead paper set. **Auditor cross-check:** the +0.838 figure belongs to the
-*synthetic dry calibration pass*, a separate artifact from the confirmatory record; the confirmatory
-sealed sweep's per-cell exploratory Spearman tops out at +0.794 (B=8/α=1) and the pooled confirmatory
-ρ is +0.6244 — so +0.838 is correctly presented as a *calibration preview*, not mislabelled as a
-confirmatory number.
-
-**D3. RQ3 double-null framing. PASS.**
-Both RQ3 nulls are reported as findings with equal prominence, not spun:
-- **Perf null** is attributed to a *baseline retention ceiling* (every arm heals ~all churn,
-  retention ≈ 0.99, margin −0.6pp), i.e. "no headroom," and explicitly says the agent "is not worse …
-  merely not better." It does **not** re-frame a null as a win.
-- **Latency** correctly holds the ≤100ms budget (−13.5ms, CI upper 34.9ms) and the paper is careful
-  that P1 fails on the *perf* gate, not latency.
-- **P2 non-exclusion** is framed as a **power** limitation at n = 30 ("underpowered to exclude a small
-  rebuild-timing signal … rather than a false all-clear"), never as "no fingerprint exists."
-This is the correct, non-spun reading of AUC 0.587 with CI upper 0.703 > 0.60.
-
-**D4. Calibration-vs-confirmatory AUC separation (no HARKing). PASS — explicitly verified.**
-The §3-4 calibration AUC ≈ **0.93** is *churned(kp30)-vs-low-churn(kp5) regime* discrimination on
-labelled control signals; the confirmatory RQ3-P2 AUC = **0.587** is *agent-vs-pooled-baseline-selector*
-discrimination on the confirmatory cells. The paper keeps these **distinct** in both §5 (parenthetical
-disclosure: "a different comparison … the calibration validated the instrument and does not preview
-the confirmatory selector value") and the sealed `honest_disclosure`. The frozen detector
-(`rebuild_classifier_auc`, per-run mean inter-rebuild-gap) is the same instrument in both, not tuned to
-confirmatory data — no HARKing, no detector-to-data fitting.
-
-**D5. Nulls / mix reported as results, with equal prominence. PASS.** The abstract, §5, and §6 all
-carry the double-null and the mix with the same weight as any positive finding; scope & limitations
-(§6) bound both to the lab grid.

-## Persona 3 — REPRODUCIBILITY AUDITOR (number fidelity & provenance)
-
-**R1. Number fidelity, RQ2-P3 (paper ⟷ `rq2p3-confirmatory-results.json`). PASS.**

-- RQ3-P3 = **H0** (p1_holds=false ∧ p2_holds=false). ✓
-- Holm-7 rows / survivors / non-survivors reproduce the sealed `authoritative_holm7` (see M1). ✓
-
-**R3. Ollama temp-0 cross-hardware caveat. PASS.**
-The paper states, with equal prominence to the RQ1 timing caveat (§4 and §6-scope-(iii)), that the
-agent (`qwen2.5:3b`, local Ollama, temperature 0) is **not bit-identical across machines**
-(quantization / GPU logit drift) and is reproducible via the **committed decision-log + (seed,
-state-hash) cache replay**, *not* via independent model re-execution on other hardware. This matches
-the sealed `honest_disclosure` verbatim in substance.
-
-**R4. Prereg SHAs intact. PASS.** Recomputed on disk: lead `f22331a72e…` and RQ2-P3 `8db4e8a7…`
-both match their pinned values and the sidecar; neither prereg file was edited by this review or by
-the fills. The sealed record digests `5fdcb379…`, `e09c66ef…`, `5b61e461…` all recompute exactly.
-
-**R5. Blinding integrity — Results filled once, post-seal. PASS.**
-Git history: scaffold authored blind (`4f89a90`); a prose-only QA fix (`50b1701`); RQ2-P3
-Results/Discussion filled **after** its battery sealed (`e0d865d`, following `f920516` STEP-2 seal);
-RQ3 Results/Discussion filled **after** the RQ3 seal (`1b6449b`, following `47faee3`). Each track's
-Results were filled **once**, from its sealed record, with no pre-seal fill and no re-slice/re-fill.
-Consistent with the un-blinded header and §5/§6 provenance notes.
-
-**R6. Containment framing. PASS.** RQ2-P3 ran offline + deterministic ($0, no engine/traffic/grid);
-RQ3 ran operator-GO'd on the isolated docker grid (`live-docker-e2e`, self-generated fixture
-traffic), agent arm local/open-weight ($0, frontier arm inert). The paper's framing is
-defensive-measurement throughout; no containment line is crossed or implied.
-
----
-
-## Defect found and corrected (1)
-
-- **Holm-7 monotonicity read as a possible arithmetic slip (prose clarity).** In §5 the three RQ3
-  non-survivors are listed as RQ3-P2 (rank 5 ×3, 0.511), RQ3-P1-perf (rank 6 ×2, 0.511),
-  RQ3-P1-latency (rank 7 ×1, 0.511). A reader recomputing the bare rank-products would get 0.354
-  (rank 6) and 0.497 (rank 7), not 0.511 — the reported values are the **step-down monotone-enforced**
-  Holm adjusted p (a later rank never reports a smaller adjusted p than an earlier one), which is
-  correct but was unexplained. Added a one-clause parenthetical stating the monotonicity so the values
-  cannot be mistaken for an error. **No number changed** — the 0.511 values are the Holm-correct
-  outputs and were already faithful to the sealed record; only an explanatory clause was added.
-
-## Residual honest limitations (carried, not defects)
-
-- **RQ3-P2 is underpowered (n = 30 runs/arm)** to exclude a small rebuild-timing fingerprint; the
-  non-exclusion is a power limitation, reported as such, not a proof of a fingerprint nor a false
-  all-clear. Carried openly in §5/§6.
-- **RQ3 perf null is grid-bound**: it follows from a baseline retention ceiling under the pinned
-  churn (kp30/steps20) on this small grid, not a general claim that adaptive selection cannot help.
-- **RQ2-P3 mix is an as-instrumented concentration effect** on the ratified exit-signature posterior,
-  not an internet-scale claim.
-- **Agent-arm reproducibility** is via committed decision-log + cache replay, not cross-hardware model
-  re-execution (Ollama temp-0 drift) — stated with equal prominence to the RQ1 timing caveat.
-
-**Outcome:** the combined companion paper is internally consistent, number-faithful to both sealed
-records, spin-free (both nulls and the mix reported with equal prominence), multiplicity-correct
-(authoritative Holm-7 reproduced independently), and blinding-honest (each track filled once,
-post-seal), after the one monotonicity-clarity prose fix. Both frozen preregs are intact. Ready for
-operator review.

-//! R5 — In-band consent handshake + X25519 hop credentials.
-//!
-//! Recruitment into a SOR circuit is **opt-in and signed**. A host broadcasts a
-//! signed `{"_sor":{"op":"request",...}}` control frame (invisible to the
-//! zero-knowledge server); each node renders accept/reject. On accept the node
-//! returns an ephemeral hop credential **sealed to the host's X25519 key only**
-//! (`crypto::seal_to_pubkey`), so no third party — not even another room member
-//! or the relay — can read it. Requests are signed with the Ed25519 persona and
-//! verified with `persona::verify` before anything is accepted: an unsigned or
-//! forged request is rejected and never yields a circuit entry.
-//!
-//! This module is the protocol + its wire parser. It performs no I/O, opens no
-//! socket, and stands up no forwarder — those are R4, gated by the
-//! isolated-engine assertion. Here we only decide *who* may be recruited and
-//! mint the per-hop secret; the frame parser inherits the never-panic proptest
-//! discipline of `net.rs`.

-//! R1 — Seed plumbing for SOR determinism.
-//!
-//! This module is the single source of stochasticity for the SOR
-//! (self-observing-relay) measurement instrument. Every stochastic decision the
-//! later items make — path selection (R4), churn schedule and selector choices
-//! (R7), padding jitter (R4) — draws from a `SorRng` seeded by one `--sor-seed
-//! <u64>`. Given the same seed and the same (deterministic) churn script, the
-//! circuit-build sequence is byte-identical across runs, which is exactly the R1
-//! acceptance check and instrument-validation gate item 2 (seeded bringup
-//! reproducible).
-//!
-//! Nothing here forwards traffic, opens a socket, or spawns an engine. It is a
-//! deterministic bookkeeping primitive; the isolated-engine containment
-//! assertions live with the forwarder (R4). The algorithm is fully specified
-//! (SplitMix64 + SHA-256 domain mixing + Lemire bounded sampling) so it is
-//! stable across compiler/`rand` versions and is mirrored bit-for-bit in
-//! `cmd_chat/sor/config.py`.
-
-// R5 — in-band consent handshake + per-hop X25519 sealed credentials. Lives in
-// its own module; it consumes this module's determinism only indirectly (a hop
-// secret is sealed per recipient) and adds no new source of stochasticity here.
