Pairing ruling (docs/stage-05-rq1p2-pairing-clarification.md, RATIFIED-by-
derivation, made while BLIND): the frozen §6 L197-198 "paired" bootstrap pairs
the bridge-on (no-pad) and bridge-on+padding arms BY RUN INDEX — the only
balanced pairing the R=30 (§4 L111) interleaved (§3 L97) design supports; the
§4 L108 RQ1 unit is AUC over the (entry,exit) pair set, so the pairable unit is
the run, not the circuit. Prereg SHA untouched (f22331a72e…).
confirm_load.collect_rq1_p2_paired feeds one confirm.PairedCircuit per shared
run_index into the FROZEN confirm.rq1_p2_padding (§6 arm-level ΔAUC preserved);
per_run_delta_aucs exposes the auditable per-run ΔAUC_i; missing-arm indices are
unpaired (frozen R not redefined). Unit-tested on SYNTHETIC pcaps only
(prereg §2 blinding — unblocks CODE not RESULTS); full SOR suite 176 passed.

Flip docs/stage-05-rq2-posterior-clarification.md PROPOSED->RATIFIED (operator
Andre, 2026-07-20, ratified while BLIND to RQ2 data — honest prereg-completion of
a gap the freeze left, not HARKing). Substance of the construction unchanged.
Add cmd_chat/sor/analysis/confirm_load_rq2.py: reconstructs each circuit's spec
OFFLINE from the persisted per_circuit_seeds via deterministic assemble(), derives
the observation-consistent anonymity set A_i (uniform / max-entropy -> [1]*m_i),
per-circuit Miller-Madow H_i, and the willing-bridge concentration series — the
exact inputs confirm.rq2_p1_delta_h (ΔH, two-sided) and rq2_p3_funnel (Spearman ρ)
consume. Grounded only in the ratified rule ([Serjantov2002]/[Diaz2002]).
BLINDING preserved (prereg §2): ratification unblocks CODE, not results. The
collect_* real-data entrypoints are BLIND-GATED and NOT run; the reconstruction is
unit-tested on SYNTHETIC specs/seeds only (test_sor_confirm_load_rq2.py, 6 passed;
full SOR suite 172 passed). Frozen prereg untouched; no RQ2 statistic computed.

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-diagonal=unlinked) so confirm.rq1_p1_leak scores measured data — the
frozen §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 only (prereg §2 blinding — no
inspecting intermediate confirmatory results before the battery
completes). RQ1-P2 nopad/pad pairing + all RQ2 held for the operator
ruling (NEEDS-OPERATOR: RQ2 per-circuit posterior underspecified).

Measures RQ1 bridge-correlation AUC + RQ2 Shannon entropy from REAL
per-hop pcaps of live isolated-docker circuits. run_battery(live=False)
hard-raises and the executor refuses (ExecutorError) any DV it did not
measure — the executor-side twin of the launcher's "never fabricate
cells" guard. Wired into confirmatory_run's triple-locked tokened GO
(executor.run_battery(live=True) behind operator token + verified frozen
prereg SHA + engine!=local + green preflight + full grid).
Containment intact: self-fixture bytes only, isolated engine only, no
external target. Frozen prereg untouched (SHA f22331a72e…).
Verify: test_sor_executor.py 7 + confirmatory_run + full SOR suite = 163
passed; preflight green (grid 3/3, READY); no confirmatory data collected.

Wire the live per-cell condition assembler (cmd_chat/sor/assembler.py): compose
the existing R1/R4/R5/R6 pieces into a condition-encoding CircuitSpec per frozen
§2 cell, so a cell_id maps to a genuinely distinct, ForwarderPlan-gated
(engine != local) isolated circuit rather than the plain 3-hop control:
- RQ1 bridge-on / on+padding insert a live bridge hop (+ R1 PADDING stream);
- RQ2 bridge-/directory-federated genuinely span >= 2 houses
(federation.select_federated_path, split-knowledge).
Plans only: opens no socket, moves no traffic, stands up no engine.
battery.assembler_dry_check validates on FIXTURES (6/6 cells distinct
fingerprints, all isolation-gated, same (cell,seed) reproduces, RQ1 bridge +
padding arms live, RQ2 federation >= 2 houses); write-once, kept out of any
confirmatory data dir. confirmatory_run preflight now runs it; the --operator-go
path no longer refuses cells as "not wired" — triple-lock + green preflight HOLD
on grid completion, then surface the operator's immutable data-run gate. No
confirmatory cell is ever fabricated.
Start-line instrument-validation gate (cmd_chat/sor/gate.py), grid + containment
pin (grid.py), and the guarded launcher (confirmatory_run.py) land alongside.
Holm: hold family_size = 7, report the 4 RQ1/RQ2 tests -> multipliers 7,6,5,4.
This is the pre-registration, not a deviation (prereg §6 [APPROVAL] size-7 family
+ D6 disclosure in the lead paper); docs/stage-05-holm-clarification.md marked
RATIFIED. RQ3-fold and alpha-split declined.
Containment intact; prereg untouched (SHA f22331a72e...); worktree-only. output/
gitignored (runtime artifacts, never source). Full SOR suite 156 passed. No
confirmatory data collected — the live data run remains the human gate.

Enumerates the frozen §2 confirmatory cells (3 RQ1 bridge levels + 3 RQ2 topology
levels at their controls; bridge-off+padding recorded as a declared N/A, not run),
derives each run's seed by the frozen §4 rule (SHA256('<S0>|<cell_id>|<run_index>')
big-endian first 8 bytes -> u64, S0=20260719), and lays out the §2 schedule with
run order randomized within each cell and each RQ's control interleaved before and
after its treatments.
write_cell_plan emits the auditable cell x run plan artifact (R=30, C=50 -> 180
runs / 9000 circuits, seed rule, matched-N rule, full schedule). dry_pass exercises
the R2/R3 provenance pipeline on FIXTURES only (deterministic replay_and_seal, no
engine, no traffic) to prove schema-valid + checksummed provenance and that a seed
reproduces its circuit-build sequence. Collects no confirmatory data — that remains
the human gate.

Encodes the four lead-paper confirmatory tests exactly per the frozen prereg §6,
calibrated on synthetic ground truth only (never re-fit to cell data):
- RQ1-P1 leak: correlation AUC + BCa CI; gate = CI excludes 0.5 (D2); 0.60 CI
lower bound = separate materiality label (material / weak-but-real), not the gate.
- RQ1-P2 padding: paired ΔAUC = AUC(no-pad) − AUC(pad) over circuits; effective
iff CI > 0.
- RQ2-P1 anonymity set: ΔH = H(federated) − H(single, matched N) with Miller-Madow
per-circuit entropy; two-sided grow / honest-shrink / inconclusive by CI sign.
- RQ2-P3 mechanism: Spearman ρ(top-3 bridge concentration, per-circuit H) + CI.
apply_holm corrects the reported RQ1/RQ2 subset against the full frozen family of
7 (family_size default 7) — never re-optimised to the 4 reported. Bootstrap
p-values order the Holm step-down only; every decision is a CI gate, never a bare p.
stats.py: bootstrap CIs can now return their resample distribution so the Holm
ordering p-value comes from the same resamples as the CI.

Turnkey implementation of the frozen prereg §6 analysis plan, written before any
confirmatory data exists (analysis-precedes-data, rigor-standards §Statistics).
Pure stdlib, no I/O, no engine, no traffic — calibrated on synthetic ground truth only:
- bootstrap_ci / two_sample_diff_ci: BCa 95% CIs (10k resamples default) with a
percentile fallback when bias/acceleration terms are degenerate; seeded and
reproducible (CIResult carries method+seed for the §6 three-seed spot-check).
- miller_madow_entropy_bits: plug-in Shannon entropy + Miller-Madow bias
correction (§3 estimator).
- spearman: rank correlation for RQ2-P3.
- holm_bonferroni: step-down multiplicity correction with explicit family_size so
a lead paper reporting a subset of the frozen 7-test family still corrects
against the full family (never re-optimised to the reported subset).

Adds the RQ3 agent-selector backend as a reproducible, offline measurement
decision — not relay/data-plane traffic. Containment is untouched: the model
query is a local call to localhost:11434.
- selector.py: SelectorPolicy ABC seam; static/random/agent(heuristic) built-ins;
make_policy() resolves (strategy, agent_backend); run_selection writes a
write-once selector.json provenance sidecar.
- agent_selector.py: OllamaAgentPolicy — reproducible confirmatory arm
(temp=0 + per-run seed, decisions cached keyed by (seed, state-hash),
deterministic heuristic fallback on any model/parse failure, model weights
digest pinned for the manifest). ClaudeExploratoryPolicy — EXPLORATORY-only
stub: makes no paid call, refuses to serve as a confirmatory backend.
- provenance.py: additive selector_backend field so an agent-selected run pins
the exact model id + weights digest.

churn.py emits a seed-deterministic kill/spawn schedule (pure data — no real VM
spin/kill; the live fabric half stays gated by the containment law). selector.py
consumes the schedule and rebuilds a circuit whenever a kill drops one of its
hops, across static | random | agent strategies; the paid frontier-model agent
arm (GOAL envelope (c)) is human-gated and NOT wired — the agent strategy here is
a local stability heuristic that spends nothing. analysis/metrics.py aggregates
the four DV families (RQ1 correlation AUC, RQ2 entropy bits, RQ3 throughput
retention + rebuild-classifier AUC) into a schema-valid, write-once metrics.json.
Acceptance check green: under a fixed churn seed the selector rebuilds every
dropped circuit (every_drop_rebuilt, all strategies) and metrics.json is
produced. Python R7 selector suite 11 passed; full SOR suite 92 passed.

federation.py adds both federation modes as offline-verifiable logic (no socket,
no engine, no external target — this measures a trust model, it provides
anonymity to no one). directory-federation: a signature-gated HOUSE-PEER roster
(PeerRoster/build_peer_frame/parse_peer_frame, Ed25519-signed, forged/unsigned
rejected) merged into a pubkey->house Directory, with select_federated_path
drawing a seed-deterministic circuit that spans >=2 houses and refuses to
collapse to one — so no single house's logs hold every hop identity (RQ2 split
knowledge). bridge-member: BlindBridge holds no room key and relays only opaque
SOR tunnel bytes verbatim (chat/consent/unknown frames refused, plaintext never
read), emitting metadata-only bridge_forward R3 events. Acceptance check green:
roster signature-gated, path spans two houses, bridge is plaintext-blind. Python
federation suite 10 passed.

run_circuit_fixture stands up an isolated docker N-hop nested-SSH chain, pipes a
seed-deterministic self-generated payload through it, verifies end-to-end
delivery, captures + checksums a per-hop pcap, emits R3 events, and always tears
the circuit down. Containment is load-bearing: assert_isolated refuses
local/unknown engines up front, every hop is built through the ForwarderPlan
guard, only our own fixture bytes move between our own containers, and the runner
is wired for docker only (multipass e2e refused, not faked). Adds the sor-hop
fixture image (alpine + sshd + tcpdump, lab-relay only) and a docker-gated
acceptance test that skips where no daemon/image is present. Instrument-validation
gate item 1 GREEN: live 3-hop delivery verified, 3 distinct hops, pcaps checksum.

Land only the offline-validatable half of R7 (instrument-validation gate items
3 and 4): the detectors the gate calibrates on synthetic fixtures, never on
confirmatory-cell data. Pure stdlib functions over in-memory series — no pcaps,
no engine, no traffic, no VM fabric.
- analysis/detectors.py: shannon_entropy_bits (RQ2 anonymity-set entropy),
pearson/score_matrix/auc/linkage_auc, bridge_correlation_auc (RQ1
linkability scorer), and synthetic_bridge_fixture (seed-deterministic
known-linked / known-unlinked ground truth via the R1 SorRng).
Calibration green: entropy returns exactly log2(N) for N equiprobable senders
(gate item 4); a known-linked control pair scores AUC=1.0 and the unlinked
estimator is unbiased at chance (ensemble mean over 40 seeds = 0.498 ~ 0.5,
gate item 3). Detectors are calibrated on synthetic fixtures only — no fitting.
The traffic-moving R7 pieces (churn.py VM spin/kill, live selector rebuild loop,
metrics.json emission) are HELD for R4/R6 + a live grid and are absent here.
Python SOR suite 66 passed.

Land only the containment-refusal half of R4: the guard every SOR forwarder
must pass before it does anything — assert engine != local, or refuse. It moves
no traffic, opens no socket, spawns no engine, and builds no SSH chain.
- forwarder.py: assert_isolated (raises on local and on any engine off the
manifest allow-list), isolation_prefix (docker/multipass exec argv, no host
path), ForwarderPlan (construction IS the gate — no plan for local/unknown/
no-container). Allow-list imported from provenance so forwarder and manifest
cannot disagree about what counts as isolated.
- There is no code path in this module that returns an exec prefix for the host;
containment is structural, not a runtime flag.
The traffic-moving half of R4 (gate item 1: 3-hop self-traffic e2e delivery +
per-hop pcaps across the grid) is deliberately NOT implemented — HELD for a live
isolated engine + grid. This guard is fully verifiable offline.
Acceptance (gate item 5) green: local/unknown/no-container refused; isolated
engine accepted with the correct isolation prefix. Python forwarder suite 12
passed; full SOR Python suite 49 passed.

Add the in-band, signature-gated consent handshake that governs whether a
node may be recruited into a measured SOR circuit, plus a per-recipient
sealed box so a hop credential decrypts only with the host's X25519 key.
- crypto.rs: seal_to_pubkey/open_sealed (ephemeral X25519 -> HKDF-SHA256 ->
Fernet AEAD), reusing the existing fernet crate (no new symmetric primitive).
- sor/consent.rs: signed ConsentRequest (Ed25519 persona), node_evaluate
(reject unless the signature verifies), CircuitBuilder that recruits a hop
only on an accept it can open; parse_sor_frame with never-panic proptests.
- net.rs: {"_sor":...} control frames are live-only and classified out-of-band
by the SOR layer (parse_sor), never surfaced as chat/app events.
- cmd_chat/sor/consent.py + bridge _sor case: bit-compatible Python mirror;
the agent only observes/classifies consent frames — it never auto-accepts
and stands up no forwarder (forwarding is R4, isolated-engine-only).
Acceptance check (roadmap R5) green both languages: host recruits a hop only
after an explicit accept; a reject leaves no entry; the credential opens only
with the host key (third party cannot); unsigned/forged request -> rejected.
Cross-language KDF parity pinned by a shared known-answer vector.
Rust 75 passed; Python SOR suite 37 passed.

Adds the tamper-evident event stream that makes every DV auditable. Each
measurable moment is appended as one JSON object per line to an append-only
output/sor-runs/<ts>/events.jsonl over the closed vocabulary {consent_request,
consent_accept, consent_reject, circuit_build, hop_add, bridge_forward,
churn_kill, churn_spawn, rebuild_start, rebuild_done}; on close the file is
SHA-256'd and the digest is sealed exactly once into manifest.json (the single
sanctioned None->hash completion of the manifest).
Records carry only metadata (fingerprints, byte counts, latencies, decisions),
never message plaintext, so the zero-knowledge relay property is preserved. The
deterministic replay_fixture_circuit emits a seed-driven event stream with no
engine, socket, or traffic (containment-safe) and is the basis of
instrument-validation gate item 6.
- cmd_chat/sor/events.py: EventLog (append-only, per-record schema),
replay_fixture_circuit, replay_and_seal.
- cmd_chat/sor/provenance.py: seal_manifest (seal-once events SHA + stop ts).
- tests: replay -> schema-valid JSONL whose SHA matches the manifest;
append-only (original prefix byte-identical after further appends);
seed-determinism modulo timestamps; seal-once immutability.
Live emit wiring into the _sor handlers lands with R4/R5.

write_manifest() freezes at circuit-experiment start everything needed to
reproduce and audit a SOR run and writes an immutable
output/sor-runs/<ts>/manifest.json: the R1 --sor-seed, topology/selector/churn
schedule id, one persona fingerprint per participating node, worktree git SHA,
isolated engine kind + image digest, pip/cargo dependency freeze, and
start/stop timestamps. The events.jsonl SHA-256 field is reserved for R3.
Provenance only: no forwarder, no engine spawned. Defense-in-depth to keep
containment load-bearing, the schema refuses to record a non-isolated
("local") engine at run or node level; the binding assertion still lands with
the R4 forwarder.
- cmd_chat/sor/provenance.py: Node/RunManifest, node_fingerprint (bit-for-bit
mirror of persona.rs::fingerprint_of), git/deps capture, explicit
dependency-free schema validator.
- hh/src/persona.rs: fingerprint_of known-vector parity test.
- tests: R2 acceptance predicate (manifest present + schema-valid, non-empty
seed, >=1 fingerprint/node), immutability, containment rejection of local
engines, and cross-language fingerprint parity.

Adds the single stochasticity source for the SOR measurement instrument so
every later stochastic decision (path selection R4, churn/selector R7, padding
jitter R4) is driven by one --sor-seed and is byte-reproducible run-to-run —
the R1 acceptance check and instrument-validation gate item 2.
- hh/src/sor/mod.rs: SplitMix64 + SHA-256 domain-separated sub-streams +
unbiased Lemire bounded sampling -> deterministic select_path/bringup.
Pure bookkeeping: no forwarder, no socket, no engine. Isolated-engine
containment assertions land with the R4 forwarder.
- hh/src/main.rs: `sor-bringup --sor-seed` emits the deterministic
circuit-build sequence as JSON (observable reproducibility).
- cmd_chat/sor/config.py: bit-for-bit Python mirror so the seed means the
same thing on both sides.
- Tests (Rust proptest+unit, Python pytest): SplitMix64 known-answer vector,
same-seed determinism, seed divergence, bounded/no-panic, and a shared
cross-language parity vector asserted identically in both suites.

Optimize the native tool-calling loop for qwen2.5:3b on CPU, where it
previously invented paths (/ai/bin/bash), ran scripts it never wrote, and
silently dropped valid actions. Three changes:
- NATIVE_SYSTEM rewritten directive: explicit write→chmod→run workflow,
relative paths only, never run an uncreated file, never guess interpreter
paths, fix the cause on non-zero exit.
- New _sandbox_facts() probe injects LIVE SANDBOX STATE (real cwd, bash
path, current files) into the system prompt so the model anchors to
ground truth instead of guessing.
- OllamaProvider recovers tool calls qwen emits as <tool_call>{json}</…>
TEXT in content (brace-balanced JSON scan), so a correct action isn't lost.
- Bump Ollama timeout 120→240s: the tool turn is non-streaming and a long
write_file can exceed a tighter cap on a contended CPU box.
Live-validated (podman/Kali): 0/3 incoherent → reliable write/run with
self-correction on exit=126 for both single- and multi-script tasks.

Display-mirror hybrid (docs/plan-harness-visibility.md §2): native tool
calls now show up in the shared sandbox terminal again via inert `# `-
prefixed comment lines (comment-prefix = anti-double-run/anti-escape),
mirroring only each command. Chat de-flooded to opener + final summary.
write_file mkdir -p parent dir so relative/absolute paths both work
(fixes the regression where script creation silently failed). ui.rs
fmt_line returns Vec<Line> splitting on \n so multi-line agent output
renders as an indented block instead of one garbled row.

Implement the bounded native harness from docs/spec-native-harness.md §1.3 and
make it the default granted-!task path. The model runs host-side (no container→
host Ollama hop); only its tool calls exec in the sandbox.
providers.py:
- OllamaProvider.complete_with_tools(system, messages, tools) -> (text, calls):
one non-streaming /api/chat turn with a `tools` schema; parses message.tool_calls
(dict or JSON-string arguments). Caches tool capability (_tools_ok / supports_tools).
- ToolsUnsupported raised when the model rejects `tools` ("does not support tools").
bridge.py:
- NATIVE_SYSTEM + a 3-tool schema (run_shell / write_file / read_file), turn/byte caps.
- _run_native: seed transcript window + task → loop up to max_turns; exec each tool
call in the sandbox, feed captured output back as a `tool` message; stop on a plain
answer or the cap; stream per-call progress to chat. Degrades to _run_simple when the
provider has no complete_with_tools or the model rejects tools.
- _exec_prefix/_exec_capture/_exec_tool: <engine> exec into docker/podman/multipass/local;
paths passed as positional args + content via stdin (no shell interpolation); combined
stdout+stderr byte-capped + time-bounded. run_shell is the only intentional shell.
- Guards: DESTRUCTIVE run_shell commands are blocked (not run — no human in the loop;
use simple + /ai confirm for destructive intent); MAX_COMMANDS budget per task.
- _run_in_sandbox dispatches native|simple; default harness flipped to native.
__main__.py: default harness native (self-degrades to simple, so safe).
Offline-tested: full write/run/read loop on the local backend; destructive block
(rm -rf never executed); ToolsUnsupported → simple fallback. Live Ollama wire
validation deferred to Phase 3 bench (daemon was down). py_compile clean.

Remove the Goose agentic harness across the codebase per
docs/spec-native-harness.md §3. Goose made N sequential model calls inside the
sandbox (slow on CPU-only hardware) and forced an in-container→host Ollama
gateway that tripped the rootless-Podman slirp4netns loopback bug.
- bridge.py: delete _run_goose/_goose_argv/_goose_present + GOOSE_* consts and
the present-cache; __init__ now takes harness="simple"/max_turns=5; granted
!task runs _run_simple until the native loop lands (Phase 2).
- __main__.py: --harness {native,simple} (was {goose,simple}); drop
--goose-max-turns, add --max-turns; default harness simple.
- app.rs: /ai start accepts native|simple (plain aliases simple) instead of a
bare plain flag; refresh harness comments.
- sbx.rs: remove the in-container Ollama gateway (Docker host-gateway / Podman
slirp4netns host-loopback) and the dk_bootstrap OLLAMA_HOST env — kills the
slirp4netns loopback bug; drop Goose comments.
- bootstrap.sh: drop goose from the prereq probe.
- bootstrap-ai.sh: remove the entire Goose install block, --no-goose flag,
GOOSE_INSTALLER_URL, host config writer, and goose_bin helper.
- sandbox-bootstrap.sh: remove the in-sandbox Goose binary install + config.
- spec-goose-harness.md: banner — harness portion superseded; Podman stays.
cargo check + py_compile clean. No Goose refs remain (headroom/ untouched).

The /ai agent held a single, un-shielded websocket with no retry. Any
close — server restart, ping/idle reap, laptop sleep, a transient blip —
ended the serve loop, so run_async returned and the process exited
silently: the agent dropped from the roster with no /ai stop and no
goodbye.
- run_async now wraps the connection in a backoff-reconnect loop (1s→30s,
resets after a healthy ≥30s session). The server frees our session+name
on drop, so each attempt re-runs SRP to mint a fresh token. Only Ctrl-C
/ process kill (KeyboardInterrupt / CancelledError, how /ai stop ends
us) breaks the loop.
- _serve shields each frame via _handle_frame so one malformed/poisoned
frame — or a handler error — can't unwind the loop; ConnectionClosed
and cancellation propagate up to the reconnect loop.
- Forgiving keepalive (ping_interval=20, ping_timeout=60) so a heavy
CPU-only Ollama generation doesn't trip a false drop.
Also adds docs/spec-native-harness.md: replace the heavyweight Goose
harness with a lightweight host-side Ollama-native tool-calling loop
(model runs host-side, only commands exec in the sandbox — the
slirp4netns→host-Ollama bug disappears), and a file-by-file plan to strip
all Goose integration. Supersedes the harness portion of
spec-goose-harness.md (Podman backend stays).

Add Podman as a rootless/daemonless sandbox backend alongside Docker,
Multipass and Local, and wire Goose in as the default agentic harness
for the granted `!task` path (bridge execs `<engine> exec <name> goose
run` and streams output to chat; auto-degrades to the simple one-shot
injector when goose is absent).
Add an optional GUI sandbox track (XFCE + TigerVNC + websockify/noVNC on
:6080) summoned via `/sbx <engine> gui`, plus container-side provisioning
in sandbox-bootstrap.sh and a host-side ensure-podman.sh prereq helper.
Refresh the in-app command help to the backend-led `/sbx <engine> [gui]`
grammar and minor ui tweaks.

Agents now join under their model tag (e.g. "qwen2.5:3b" — model name +
parameter size) or profile label, derived at /ai start and tracked on
App.agent_name, so the roster shows what's actually answering. Updates the
broker re-grant + /ai stop revoke paths, the Python --name default

Two causes made a shared shell's PTY stream lag for non-host viewers and
then arrive "all at once":
1. Nagle's algorithm — PTY echo/keystrokes/chat are tiny frames; Nagle +
delayed-ACK (amplified by Tailscale RTT) coalesced them into bursts.
Set TCP_NODELAY on the client websocket (Plain/--no-tls path) and on
each server connection's socket (via ws.io_proto.transport).
2. Head-of-line blocking — ConnectionManager.broadcast awaited each
send() serially under a global lock, so the slowest viewer gated
delivery to everyone AND stalled the server's read of the broker's
next frame, backing the stream up. Give each connection its own
bounded outbound queue + writer task; broadcast now only enqueues and
never waits on a socket. A peer that overflows its backlog (4096) is
evicted (close 1013) and resyncs on reconnect rather than buffering
without bound or being fed a gapped terminal stream. Init snapshot is
enqueued as the guaranteed-first frame (send_state -> state_frame).
Adds tests/test_manager.py (FIFO, slow-client isolation, wedged
eviction, reconnect replacement). Also fmt-clean sbx.rs/theme.rs.

M1: enforce the declared transfer size (clamped to MAX_SIZE) on chunk
receipt in both the Rust and Python clients — a malicious sender can no
longer grow the receive buffer unboundedly.
M2: only honor X-Forwarded-For when TRUST_PROXY is set, so a direct
client can't spoof a source IP to dodge the per-IP rate limiter.
M3: evict unverified SRP sessions after a 60s TTL on each new handshake,
preventing half-finished auths from exhausting memory.
M4: drop WS frames larger than 256 KB before they hit the store or
broadcast, bounding per-message memory and flood blast radius.

The Python client saved an incoming transfer under the offerer-controlled
`name` field verbatim, so a peer could supply `../../…` or an absolute path
and write a file anywhere the user can (arbitrary write → RCE). Reduce the
name to a bare basename before joining it to the download dir, matching the
Rust client's existing behaviour.

- /sbx save|load|snaps: docker commit → hh-snap:<label> image that
survives /sbx stop; load relaunches a fresh sandbox from it; multipass
delegates to `multipass snapshot`. Local backend unsupported.
- Help overlay redesigned into topical clusters (SANDBOX, AI AGENTS,
PERMISSIONS, FILES, APPEARANCE, KEYS, ROSTER GLYPHS), collapsed by
default; up/down highlight a cluster, left/right/Enter expand-collapse
it (tmux-style), PgUp/PgDn scroll overflow, Esc closes.
- docstring: example uses --model qwen2.5:3b (the locally-pulled model),
not llama3.

Closes the cross-language half of token streaming (perf-plan A3). On the
CPU-only box perceived latency is time-to-first-token, so showing the reply
as it generates makes a slow model feel live.
- Agent: OllamaProvider.stream() runs on a worker thread; bridge relays
cumulative previews as throttled (~5/sec) `_ai:"stream"` control frames,
then a `done` frame clears the preview as the final persisted chat message
is posted. Providers without stream() fall back to blocking complete().
- Rust client: new Net::AiStream variant + parse_ai branch; App.ai_stream
map holds the in-progress text per agent; draw_chat renders it as a dim,
italic preview bubble below history. Cleared on done and on agent leave.

Tier A/B/C wins for the CPU-only Ollama box (no GPU → optimize TTFT and
tokens/sec, not VRAM):
- Separate qwen2.5-coder provider for the sandbox `!task` path; chat keeps
the general model. Auto-selected when chat is Ollama and a coder build is
present, override with --code-model.
- OllamaProvider num_ctx default 8192→4096 (8192 was a GPU-mindset default
that inflates prefill/TTFT on CPU); expose num_thread; add --num-ctx,
--num-thread, --num-predict. token_budget default 3000→2000 to fit.
- OllamaProvider.stream() generator over Ollama's stream=True chat endpoint
(provider half of token streaming; agent/Rust rendering is a follow-up).
- Few-shot request→shell exemplars in SANDBOX_SYSTEM to anchor the small
model's fenced-command output.
- Matryoshka embedding truncation: OllamaEmbedder truncate_dim=256 (--embed-dim)
for faster pure-Python cosine and less RAM; query+stored share the dim.
- docs/ai-perf-plan.md records all 8 items with status and the server-side
env (OLLAMA_NUM_PARALLEL=1, keep_alive) that must be set where ollama serve runs.

Give the agent recall of things said beyond the verbatim window, without
breaking the RAM-only philosophy — nothing is persisted to disk.
- MemoryIndex: a capped, in-memory pool of embedded messages with pure-Python
cosine search (no numpy). Retains far more than the rolling transcript so old
lines can be surfaced on demand; oldest evicted past the cap to bound RAM.
- OllamaEmbedder: local embeddings via nomic-embed-text, on by default and
independent of the chat provider (reuses the Ollama host when chat is Ollama).
- Bridge: captured room messages (live + backfilled) are embedded on a
background worker so a slow embedder can't stall frame draining. On a /ai
question the agent retrieves top-k relevant lines, drops weak (<min_score) and
windowed-duplicate hits, and prepends them as a clearly-fenced "recalled
context" preamble — kept at user role, never elevated to system, so untrusted
room text informs without instructing. Falls back to recency-only if the
embedder is unreachable.
- CLI: --no-rag, --embed-model, --embed-host, --rag-top-k.

OllamaProvider now sends keep_alive (default 30m) so the model stays resident
in VRAM between /ai calls instead of cold-reloading, and sets explicit options
(num_ctx 8192, num_predict 512) — Ollama otherwise caps context at 2048, which
would silently truncate the larger backfilled window.

The server already ships the full RAM message backlog in the init frame; the
agent was discarding it. _seed_transcript now decrypts that history with the
room key (skipping our own lines, control frames, and undecryptable blobs) so
the agent has context the moment it joins instead of starting amnesiac.
_window() replaces the fixed last-12 slice on both the answer and sandbox
paths: it walks newest-to-oldest and keeps messages up to --token-budget
(approx, ~4 chars/token), still capped at --context-window count. Keeps small
local models inside their effective context. Nothing touches disk.

Agents can now run commands and build files in the shared sandbox, but
only when explicitly invoked with the `!` verb and only while the owner
has granted drive. Reuses the existing driver ACL + `_sbx:input` frames:
the Python agent emits the same input frames a human driver does, gated
by the broker's `app.drivers` check — no new transport.
Guardrails: a regex gate holds destructive commands until `/ai <name>
confirm`; blast-radius caps (20 cmds / 8KB); the agent echoes its plan to
the room before running (audit trail). Owner controls: `/grant`, `/ai
start <model> allow` to pre-grant on spawn, and a Ctrl-X panic kill
switch (revoke all non-owner drive + Ctrl-C the shell). The broker now
re-broadcasts the ACL on join so a freshly-summoned agent actually
receives its grant.

Make connecting any model a config step, not a code change:
- models.toml named profiles (api_key_env names an env var, never the key)
- providers gain available_models(); add preflight + --list-models/--check
- /ai list and /ai models in-room; client probes local Ollama for
/ai models when no agent is running, and /ai list hints to summon one
- docs/providers.md provider guide + examples/echo_provider.py
- README: command table, AI section, layout updated

Owner of the spawning client can summon/dismiss a local AI agent from inside
the room (default ollama/qwen2.5:3b); the agent emits encrypted typing frames
that drive a "thinking" spinner in the client.

Add cmd_chat/agent: a headless client that joins a room via SRP, decrypts
broadcasts, and answers /ai <question> through a pluggable model provider
(ollama default + anthropic + openai-compatible + module:Class). Server and
zero-knowledge guarantees unchanged; the agent is just another encrypted client.
Also pin the lets-hack demo to a detached worktree of main (default) so running
it from dev still demos stable main without touching the working checkout.

- add /pw (alias /password): reveal this room's password locally (never
broadcast); surfaced in the F1 help overlay and the join hint
- direnv-autostart/: cd-to-launch a single real-user session via direnv;
password is minted in memory at launch (never written to disk, matching the
RAM-only model) and scoped to the child process. setup.sh installs direnv,
hooks bash/zsh, and `direnv allow`s the dir
- lets-hack.sh: boot a FRESH server by default (replacing any live one) with a
--reuse opt-out; add -h/--help/-help; guard against killing the tmux session
you're attached to; switch-client into the coven when run inside tmux
- rename coven→clergy across rust/python/scripts; tests/test_coven.py→test_clergy.py
- snapshots in-progress hack-house client work (sandbox, themes, net, ui)

Begin the coven evolution of cmd-chat (see docs/spec-collaborative-sandbox.md):
a Rust/ratatui client for the unchanged Python Sanic server, plus the
multi-user + zero-knowledge groundwork.
P0 — crypto parity (the spec's #1 risk), proven three ways:
- Hand-rolled SRP-6a (NG_2048, SHA-256, rfc5054 padding) matching pysrp
byte-for-byte, incl. the fixed b"chat" SRP identity and minimal-vs-256B
width quirks. Golden-vector unit test + offline selftest.
- Live handshake against the running server (H_AMK verified).
- Cross-language E2E: Python client decrypts a Rust-encrypted Fernet message.
P2 — multi-user coven (server):
- CMD_CHAT_MAX_USERS capacity cap (default 4, infra-for-more).
- Authoritative roster + user_joined broadcasts.
- Free the slot/username on ws disconnect (was held until 1h stale sweep).
Also: fix requirements.txt (was UTF-16, unparseable by pip).
coven/ : Rust crate (crypto.rs proven; main.rs spike CLI: selftest/handshake/srpm)
docs/ : full feature spec for the 6 requested features.

New commands: /send <filepath>, /accept, /reject
Protocol:
- Sender proposes file (name, size, SHA-256 hash)
- Recipient sees offer and chooses /accept or /reject
- On accept: file chunked (64KB), encrypted with room key, sent over WebSocket
- On receive: chunks reassembled, SHA-256 verified, saved to ./downloads/
- Server never sees file content (E2E encrypted, same as messages)
Limits: 50MB max file size. Files saved with collision-safe naming.
No server changes — server remains a dumb encrypted relay.
All 79 existing tests pass.

CRITICAL fixes:
- Auto-generated self-signed TLS certs (HTTPS/WSS by default)
- Removed session_key from /srp/verify response (was sent in plaintext)
- Replaced with HMAC-SHA256 ws_token for WebSocket authentication
HIGH fixes:
- WebSocket auth now validates ws_token via hmac.compare_digest()
- /clear endpoint requires Bearer admin_token (printed at server start)
- Password no longer required as CLI arg — supports env var + getpass prompt
- Removed user_ip from Message model (no longer broadcast to clients)
MEDIUM fixes:
- Rate limiter on /srp/init and /srp/verify (10 req/min/IP)
- MessageStore capped at 1000 messages (prevents RAM DoS)
- access_log disabled (was leaking request metadata)
LOW fixes:
- Username sanitization against rich markup injection
- Dead code removed from helpers.py
All 79 tests passing.

Fix abstract renderer signatures and add small stubs so type checkers can
see expected attributes (e.g. username, _decrypt). This removes several
mypy false-positives that were caused by mixin/ABC mismatches.
Preserve message text containing ':' by using split(':', 1) in both
DefaultClientRenderer and RichClientRenderer.
Normalize renderer APIs: print_chat(...) now takes the response mapping
and returns None (matches runtime behavior).
Make RSA symmetric-key request more robust: read r.content instead of a
fixed-size r.raw.read(999), avoiding truncated key material.
Improve _connect_ws exception handling in client to ensure a valid
Exception is re-raised if connection attempts fail.
Correct server/service typing: memory_msgs is now typed as
list[Message] and we null-check incoming payload text before creating a
new Message.
Replace manual package list in setup.py with setuptools.find_packages()
so packaging uses valid Python package names.
Installed types-requests in the project venv so mypy no longer flags the
requests import.
Verification: ran python -m compileall and mypy cmd_chat — no issues
remain.
Notes:
Wire format still uses Python literal evaluation in some places (existing
behavior); switching to JSON for client/server payloads is recommended as a
follow-up for robustness and security.
