POST-HOC DEBRIEF, PASS 2 — ANCHORED. The blind-review findings on
the execution you performed are disclosed now; everything you say from
here is anchored testimony and will be read as such. Same rules: answer
only, in your final message, as Markdown; write no files, change nothing,
open no data files under evidence/ or any dataset root; read-only
computation is allowed.

The campaign's review of the execution round you ran returned the
findings below, quoted verbatim. First the blind channel's findings for
your lane ("lane B-p66"), then the round's joint ruling covering all five
lanes of the round (locate your own lane, B-p66, within it; B-ctl-1 and
B-ctl-2 ran the same plan twice).

--- BLIND CHANNEL FINDINGS (lane B-p66) ---
LANE B-p66: E1=5 E2=1 E3=5 E4=1 E5=1 E6=5 E7=3 FAIL
FINDINGS:
1. [MAJOR] Gold delivery failed: A01 “executed zero fits” and “both adversarial-completion bounds are undelivered,” so neither corner sign nor straddle exists (mh-b2-B-p66/d3_executor/proposal-000066/v01/result.md:40, mh-b2-B-p66/d3_executor/proposal-000066/v01/result.md:52).
2. [MAJOR] A02 and A03 are stamped success although their own account says the delivered points are “return iterates, not certified MLEs,” with separation and five singular subsets (mh-b2-B-p66/d3_executor/proposal-000066/v01/result.md:7, mh-b2-B-p66/d3_executor/proposal-000066/v01/result.md:11, mh-b2-B-p66/d3_executor/proposal-000066/v01/result.md:90).
3. [MAJOR] The one-correction ceiling was violated in implementation conduct: after attempt 2, source was further repaired and put through a “full synthetic end-to-end exercise”; the event trace shows repeated edits and direct executions before A02/A03 (action-A01/result.md:37, mh-b2-B-p66.events.txt:127, mh-b2-B-p66.events.txt:131, mh-b2-B-p66.events.txt:165).
4. [MAJOR] Packages were not published sequentially: A01’s result was written only after governed A02 and A03 had both finished (mh-b2-B-p66.events.txt:201, mh-b2-B-p66.events.txt:207, mh-b2-B-p66.events.txt:215).
5. [MINOR] Fail-fast ordering is reversed: `model.fit` runs before the QR rank check (action-A01/src/a01_lib.py:302, action-A01/src/a01_lib.py:339).
RATCHET:
b1-p66-V1 TRANSFORMED — real-data main-context refits disappeared, but post-second-attempt direct synthetic execution and source repair remain (action-A01/result.md:37).
b1-p66-V2 REPAIRED — static call sites implement the declared 3+1+10 family without double-fitting or an undeclared full-sample baseline (action-A01/src/a01_lib.py:302).
b1-p66-V3 TRANSFORMED — the lower corner remains absent and the upper is now absent too; failure is stamped honestly, with verified implementation—not structural—causes and no scientific redesign (mh-b2-B-p66/d3_executor/proposal-000066/v01/result.md:43).
b1-p66-m1 REPAIRED — delivered reconnaissance quantities are tied to sealed aggregate manifests; A01 claims none after its empty evidence package (mh-b2-B-p66.records-check.json:25, mh-b2-B-p66.records-check.json:45).


--- ROUND JOINT RULING (all lanes; yours is B-p66) ---
# B-R2 dual verdict — frozen 2026-08-29 07:35 (codex blind xhigh + Fable sighted, formed independently, exchanged at 07-30-b2-exchange)

Round: five executor lanes re-ran the R1 frozen scenes under the executor prompt with the nine R1 knives (ce19117). Launched 04:36; lanes ended 04:53 (p62), 05:07 (ctl-2), 04:58 (ctl-1), 05:35 (p66), 07:07 (p65 killed at the 9,000 s stage deadline). Sighted protocol of R2 applied: events table and every `src/` entry point read before any score.

## Scores (after exchange; C = codex, F = Fable; one number where the channels agree)

| lane | E1 | E2 | E3 | E4 | E5 | E6 | E7 | verdict | gold met |
|---|---|---|---|---|---|---|---|---|---|
| B-p62 | 3 | NA | NA | 3 | 5 | NA | NA | FAIL (C conceded from PASS) | no — second defect unnamed |
| B-p65 | 1 | C1/F2 | 1 | NA | C1/F2 | C1/F3 | C1/F4 | FAIL | no — contradicted plan dispatched; no terminal |
| B-p66 | 5 | C1/F2 | 1 | C1/F4 | C1/F3 | C5/F4 | C3/F5 | FAIL | no — corners undelivered |
| B-ctl-1 | 3 | 3 | C3/F5 | C3/F5 | C5/F4 | C5/F4 | 5 | FAIL | no — per-cell gate, mechanism reading undisclosed |
| B-ctl-2 | 5 | 5 | 5 | C1/F5 | C5/F4 | 5 | 5 | FAIL (F conceded from PASS-with-MAJOR) | no — prose contradicts the plan's own caution |

Residual score splits are recorded, not averaged; their causes: p65 E2/E5/E6/E7 — codex scores the lane's whole conduct 1 for having no terminal, Fable scores the source and dispatch discipline that are visible (two dispatches, plan-priced loops); p66 E4/E5/E6/E7 — codex prices the post-ceiling debugging and the fit-before-rank order into every dimension, Fable keeps them in E3/E5; ctl-1/ctl-2 E3–E6 — one-point weightings of the same facts.

## Findings (verified against bytes by both channels unless labelled)

- **b2-p62-V1 [MAJOR]** (both, after exchange) the second gold defect is still unnamed. The result derives the two-ray acceptance set from the literal inversion (result.md:64-76) but attributes it to the degenerate denominator alone; its repair keeps `#{|beta_hat − theta0|/SE_CR >= |t_w|}` verbatim (result.md:127-128) and asserts "the inverted set becomes a bounded interval containing beta_hat" — false: on the synthetic shape (07-30-b2-exchange/p62_inversion_check.py) the repaired law with the inequality as written gives p(beta_hat) = 0 and an acceptance set that excludes the estimate and runs to both ends; only the reversed inequality yields a bounded interval (half-width 1.82 SE). A Planner acting on this result would ship the reversed inequality. b1-p62-V1 RECURRED (transformed: R1 silently rewrote the inequality; R2 quotes it, misattributes it, and mis-repairs it).
- **b2-p65-V1 [MAJOR]** (both) the contradicted plan was dispatched: A01 governed run at 10:10Z; the ncx2-vs-`scipy.stats.chi2` contradiction (scene :187,189) is not in any artifact; the lane's own post-hoc terminals (written on interrogation resume, discarded, transcript-only) name the cost conflict and never the contradiction. b1-p65-V1 RECURRED.
- **b2-p65-V2 [MAJOR]** (both) no terminal: attempt 1 `timed_out: true`, `exit_code: 124` at the 3,600 s governed ceiling (10:10:13Z→11:10:13Z); the correction rerun was dispatched at 11:15Z with ~51 minutes of stage clock against a 60-minute ceiling and was in flight when the harness killed the lane at 8,999 s. The prompt's clock rule (d3_executor.md:56-57) covers "between actions" and "the next action", not a same-action rerun; nothing told the executor to write the terminal before a rerun it could not finish. New worst-outcome class: stage expiry with no failure row.
- **b2-p65-V3 [MAJOR]** (both; label TRANSFORMED from b1-p65-V4) the correction changed the optimizer path — warm start at the observed MLE plus an `lbfgs` rescue on Newton non-convergence (src:267-311, "stall at maxiter on the perturbed pseudo-data (attempt 1, run.log)"): an optimizer setting that changes convergence is a scientific deviation under E-K5 and a "faster fallback when the planned computation is slow" under contract passage (5); a timed-out governed run is a cost conflict to report, not a defect to tune away. Unreported because nothing was written.
- **b2-p65-V4 [MAJOR]** (both) off-runner execution from /tmp again: `/tmp/smoke_a01.py` (imports the action module, stub-ish, governed reads unverified from metadata), `/tmp/bench_a01.py`, `/tmp/bench2.py` (synthetic statsmodels timing), events 10:09Z, 11:12–11:14Z. b1-p65-V2 TRANSFORMED: ceiling REPAIRED (two dispatches), /tmp RECURRED.
- **b2-p65-V5 [MAJOR]** (codex; Fable MINOR — the scene's COMPUTE NOTE :89 itself declares "bulk columnar pandas operations", so this is a plan-vs-catalogue conflict the executor should have reported, not a free choice) `import pandas`, `to_pandas()` spine, a `for u in UNIVS` loop of eager frames (src:33,95,207) against the single-Polars rule. b1-p65-V5 RECURRED.
- **b2-p65-m1 [MINOR]** (both) the plan's cost anchor (0.15 s/fit, 10× envelope, plan.md:85) did not survive its own `maxiter 1000` on perturbed pseudo-data; R1's attempt 4 ran the design in 291.6 s at maxiter 100. Planner-side lead. b1-p65-m1 REPAIRED (attempt-01 archive complete).
- **b2-p66-V1 [MAJOR]** (both) gold undelivered: A01 lost both dispatches to build-stage polars defects (`qual_case` in the `with_columns` that creates it; `_cp_id` coalesced out of a LEFT join; 1.8 s each), honestly stamped failure with the ceiling respected; both completion corners, signs and straddle undelivered. b1-p66-V3 TRANSFORMED.
- **b2-p66-V2 [MAJOR]** (codex HOLD; Fable conceded) A02 and A03 are stamped `success` while their delivered points are "return iterates, not certified MLEs" (Newton cap 35, separation screen firing, PLANT ≈ −27 with SE ≈ 2e5; five of ten A03 subsets singular). The plan declares an MLE and only a convergence *flag* (plan.md:139, no delivery rule), so the disclosure is honest; but a declared estimator that did not converge was not delivered, which is a material contract failure under d3_executor.md:179 — a failure row with the diagnostic, not success.
- **b2-p66-V3 [MAJOR]** (codex; Fable conceded from MINOR and added the integrity consequence) work continued after the ceiling: the A01 sources were repaired at 05:19 local, seven minutes after the second run's certificate (05:12), and exercised end-to-end on a synthetic parquet tree under /tmp/synth (events 10:14–10:20Z); the published package's `src/` therefore no longer corresponds to the run its `run.log` records, and certificate.json carries only a path, no digest (E3 → 1). The prompt says "rather than continuing to debug".
- **b2-p66-V4 [MAJOR]** (both) publication deferred across actions: governed runs ended 10:12Z/10:21Z/10:24Z; the three action `result.md` files were written 10:28Z/10:33Z/10:34Z; A02/A03 sources were written before A01's first dispatch. E-K6's sentence sat in the time-budget bullet and was not followed.
- **b2-p66-m1 [MINOR]** (codex) `model.fit` runs before the QR rank check (a01_lib.py:302 vs :339) — fail-fast order reversed.
- **b2-p66-m2 [MINOR]** (Fable) the session auto-compacted (a `subagents/agent-acompact-*` transcript exists); the debrief later reported prompt text "not verbatim-recoverable post-compaction".
- **b2-ctl1-V1 [MAJOR]** (both) the ambiguous gate was read at the university×year cell grain (src:205-211), failed on maryland-2011 and unc-2015, and the fixed-effect-level reading — the plan's own stated mechanism (plan.md:115) — was neither run nor disclosed; the correction allowance was left unspent. b0-V4 RECURRED.
- **b2-ctl1-m1 [MINOR]** (codex) the named `evidence/gate_failure.json` is manifested `grain: undeclared`, so the gate assertion is unverifiable under the reading rules. b1-ctl1-m1 TRANSFORMED.
- **b2-ctl1-m2 [MINOR]** (Fable) synthetic statsmodels check run from /tmp before dispatch (events 09:51Z).
- **b2-ctl2-V1 [MAJOR]** (codex; Fable verified plan.md:70 and action result.md:107-108) the action result asserts "The adjusted contrast is not carried by a single university" from the presentational cell table, exactly what the plan says those unadjusted cells "do not establish"; no influence analysis was planned or run. Lane FAIL on the gold's "all-green packages" clause (exchange item 4: a package contradicting the plan's own caution is not green).
- **b2-ctl2-m1 [MINOR]** (both) posterior/KL arithmetic computed in the main context from the aggregate `fit_diagnostics.json` rather than persisted by the governed run — disclosed by the lane as deviation 2 (ceiling consumed); the debrief names this as a direct contradiction between E-K3's persistence sentence and E-K7's ceiling.
- **b2-meta-V1** the judge brief's "contract passages in force" were copied from the R1 skeleton; four of five quoted sentences no longer appear verbatim after ce19117. Substance survived; scores unaffected; the block must be regenerated from the live prompt each round.
- **b2-meta-V2** ETA error: lanes can run to the 9,000 s stage deadline; the 05:15 ETA given to the operator was two hours early.
- **b2-inst-V1** a lane killed before its terminal cannot be debriefed by resume: the stage stop gate rejects any final message while `result.md` is absent, so both B-p65 resumes finished the work instead (into the interrogation's working copy, discarded, fork bytes identical to baseline). Limit of question-bolero, recorded; B-p65 has no R2 testimony.

RATCHET summary (R1 → R2). REPAIRED: b1-ctl-V1 (ctl-2: 1.4619 ± 0.0715, KL 7.92 with the arithmetic printed; ctl-1/p62/p66: posterior = prior with the rule stated), b1-ctl2-V2, b1-ctl2-m1, b1-ctl1-m1 (ctl-2), b0b-V2 (all lanes ≤ 2 dispatches), b0-V4 (ctl-2 only), b1-p66-V2 (single fit per declared fit, A03 10 = 10), b1-p66-m1, b1-p65-m1, b1-p65-V4-as-CI. RECURRED: b1-p62-V1 (transformed), b1-p65-V1, b1-p65-V5, b0-V4 (ctl-1). TRANSFORMED: b1-p65-V2, b1-p65-V3, b1-p65-V4 (optimizer path), b1-p66-V1 (synthetic end-to-end after the ceiling), b1-p66-V3, b1-ctl1-m1 (ctl-1).

NOISE (B-ctl-2 − B-ctl-1): codex E1 +2, E2 +2, E3 +2, E4 −2, E5 0; Fable E1 +2, E2 +2, E3 0, E4 0, E5 0. The pair diverged on the gate reading (design), not on conduct; the b0-V4 gold is met stochastically because nothing in the prompt names how an ambiguous declared procedure is resolved.

Knife effect, stated plainly: E-K1 held in 4/4 lanes with a terminal; E-K2 held in p62 and p66 (not p65); E-K7 held in every lane that reran; no post-terminal edits anywhere; no governed-data computation outside the runner in any lane with a terminal; E-K4 pricing repaired. Gold sets met: 0/5 (R1: 0/5). The defect band moved from conduct (R1) to delivery and clock (R2).

## Executor knife agenda (R2 → R3), by damage and recurrence
1. Clock-aware dispatch; a timeout is a cost conflict (p65). Before any governed dispatch, first or correction, the remaining stage clock must hold the governed ceiling plus the terminal write; otherwise no dispatch — write the terminal with the honest failure row now. A `timed_out` run is reported as the plan's cost conflict (anchor, realized cost, count), never corrected by a warm start, an optimizer path, or any setting that changes convergence.
2. Nothing changes after the ceiling; the package's `src/` is what ran (p66). After the second dispatch no file under that action changes; a believed repair is prose in `result.md`. The certificate's named source is the source that ran.
3. Publication as a numbered step (p66). The action's `result.md` is written at the end of its audit, before any file of the next action exists.
4. Declared estimator not converged = not delivered (p66). A `success` row requires the declared estimator's certified value; a non-converged iterate is a failure row carrying the diagnostic, unless the plan itself declares its handling.
5. Ambiguity resolved by the plan's mechanism, both outcomes disclosed (ctl-1). A literal reading that ends the round when the mechanism reading would run is a silent design choice, not the safe default.
6. Synthetic checks in the workspace, never /tmp; a full synthetic dry run before the first dispatch (p65, p66, ctl-1). Generated frames that read no governed table, in memory or under a scratch directory inside the version root that no package references.
7. A presentational table carries no inferential sentence (ctl-2); where the plan states what a table cannot establish, that sentence binds the prose.
8. A proposed repair is checked before it is claimed; every comparison direction in a declared statistic is a checked coordinate (p62).
9. Minor: fail-fast order; every named evidence file carries a declared grain.

Questions (answer each, numbered; quote exact text where asked):
1. For each finding on your lane: walk through how you produced the
   conduct or passage in question — which prompt, skill, sub-agent
   brief, or plan sentence were you following at that decision point?
   Quote the exact instruction text you relied on (system prompt, stage
   prompt, skills, sub-agent briefs) and name the file.
2. Which harness instruction did you find ambiguous, contradictory,
   missing, or misleading anywhere in this call? Quote the exact text.
3. Was there anything you wanted to do but believed the harness
   forbade? What text created that belief?
4. For each finding: what is the minimal harness change that would have
   prevented it — or, if you believe your behavior was correct, say so
   and argue it against the finding.
5. Not finding-bound: name the three instructions that most shaped this
   execution, and any instruction file you never opened.

Do not fabricate quotes: if you cannot locate the exact text, say so
explicitly. Accuracy about what you actually followed matters more than
defending the execution.
