Operator-authorized (D1: freeze + run). New harness analysis/rq2p3_confirm.py
runs the frozen §4 battery entirely offline: all 9 sweep cells (B∈{2,4,8} ×
alpha∈{0,1,2}; B=50 anchor excluded) × R=30 × C=50 = 13,500 bridged circuits.
RQ2 entropy is analytic and pool bridge assignment is deterministic from the
seed, so no engine, no traffic, no grid, $0 — the same offline reconstruction
path confirm_load_rq2 uses for the lead RQ2. Seeds per frozen §6: run =
derive_seed(S0=20260719 ‖ cell_id ‖ run_index), per-circuit = the live
executor's real _circuit_seed rule (byte-identical). The frozen instruments
(stats.py, confirm.py, confirm_load_rq2.py, assembler.py) are UNCHANGED — the
only new code is seed enumeration, run-as-unit grouping, and an OLS-slope helper.
Frozen §8 analysis (effect + BCa 95% CI, never a bare p; 10,000 resamples;
α=0.05; run-level cluster bootstrap):
H1 pooled Spearman ρ(c_i,H_i) = +0.6244, CI [+0.5941, +0.6545] -> mix
H2 OLS dose-response slope = +0.7052, CI [+0.6195, +0.7903] -> mix (n=270)
H3 joint -> RESOLVED = mix (both exclude 0, agree in sign)
Holm over own family {H1-pooled, H2-slope}, size 2: both reject.
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;
the two-sided pre-commitment stood. The +ρ MIX qualifies/corrects the lead
RQ2-P1 "shrink" headline as a unique-bridge artifact — a shared finite bridge
pool RAISES the per-circuit anonymity set, the opposite of the naive funnel.
That correction is the finding, reported openly. The lead RQ2-P1 result is NOT
re-litigated; any pool ΔH is exploratory (prereg §1).
Sealed immutably under output/ (gitignored → anchors force-added):
rq2p3-confirmatory-results.json (SHA-256 5fdcb379d8a2…) + SHA256SUMS;
byte-identical on re-run. Both prereg SHAs verified intact (lead f22331a72e…,
RQ2-P3 8db4e8a7ac60…). Tests: tests/test_sor_rq2p3_confirm.py 7 passed; full
SOR suite 201 passed, no regression. Defensive-measurement instrument only;
worktree-only on feat/sor-consent-relay.

One auditable, deterministic run of the four lead-paper §6 tests on the
frozen raw battery. Calibration gate PASS (linked AUC 1.0000, unlinked
0.5036 on §5 fixtures) → AUCs reportable.
- RQ1-P1 (bridge leak): AUC 0.4660 CI[0.4523,0.4798] = anomaly-below-chance.
NO measurable leak; Holm-sig but in the WRONG direction (not evidence of
linkability).
- RQ2-P1 (federation): ΔH −0.9587 bits CI[−1.056,−0.864] = SHRINK. Holm-sig
HONEST-NEGATIVE — federation reduces the anonymity set (opposite of RQ2's
motivation); reported with equal prominence per §6 two-sided framing.
- RQ1-P2 (padding): ΔAUC +0.0113 CI[−0.0025,+0.0234] padding-ineffective
(raw p 0.091, Holm adj-p 0.456, not rejected).
- RQ2-P3 (funnelling): Spearman ρ=0, zero-variance concentration =
as-instrumented degeneracy flagged in advance; inconclusive.
Holm family=7 report-4 (multipliers 7,6,5,4); only RQ1-P1 + RQ2-P1 survive.
Ran ONLY the pre-registered tests — no re-slicing, no post-hoc subgroups.
Method faithfulness: RQ1-P1/P2 CIs use a bit-faithful fast numpy bootstrap
(frozen O(n²)-per-fold jackknife intractable at n=75000); stage06_run.py
--verify proves both == frozen stats.bootstrap_ci bit-for-bit (point/lo/hi/
method within 1e-12, incl the average-rank tie path). RQ2-P1/P3 stay on the
frozen confirm.* paths (tractable). Frozen prereg SHA INTACT.
Artifacts: docs/stage-06-analysis.md (methods-faithful narrative, Holm table,
CONFIRMATORY/EXPLORATORY labels, nulls reported honestly) + force-added
output/…/analysis/stage06-results.json (regenerable via stage06_run).
