R7/RQ3: executor-wiring stone — offline selector DVs + calibration gate

Wire the RQ3 churn-resilience companion (severable follow-on; RQ3 frozen in its
own prereg) as SYNTHETIC/OFFLINE build + calibration only — no confirmatory
battery run.

- battery: enumerate_rq3_cells()/rq3_schedule() add selector in {static(control),
  random, agent} at 1house/bridge-off under pinned churn kp=30/steps=20, kept
  SEPARATE so the frozen 6-cell lead lattice stays byte-identical.
- executor: run_rq3_cell_run collects offline selector DVs (throughput-retention,
  drops/rebuilds, rebuild-interval gaps); added-latency is live-only (offline path
  records None, never fabricated); run_rq3_battery(live=False) hard-raises.
- analysis/rq3_calibration: DRY offline gate. Churn-bites (1589 drops/1576
  rebuilds) + rebuild-classifier calibration green with real teeth — churned(kp30)
  vs baseline(kp5) AUC 0.926 separable, baseline-vs-baseline null 0.518 blind.
  Classifier scored on the PER-RUN mean inter-rebuild gap (the confirmatory
  grouping unit); the frozen instrument (rebuild_interval_gaps,
  rebuild_classifier_auc) is untouched, no fit to confirmatory data.

HARD HOLD: no RQ3 confirmatory battery (live added-latency is operator+grid-gated).
Lead prereg SHA f22331a72e… untouched; containment intact (synthetic/offline, $0
local Ollama, frontier arm inert); worktree-only.

Tests: tests/test_sor_rq3_wiring.py 9 passed; full SOR suite 194 passed.

 - 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.
