docs(remediation): bank D-39/D-40 — gate-ready reached, then withdrawn on a finding I disclosed

Browse Source 
D-39: I contaminated an open independent review. RR12 was an open registered check and I sent rev-974
my CONCLUSION, not just my observation. rev-974 then downgraded an automated Codex review that had
flagged RR12 as a blocker, in line with my framing. The bias sat in my instrument, not the reviewer's
diligence — a subordinate is agreeable by construction, and the divergence instruction I attached
cannot undo having named the answer first. Mos adopted the rule fleet-wide: a dispatcher may relay
observations and reproductions into an open review, never its own verdict on an open check.
Re-adjudicated by a mechanically fresh seat with no access to my framing: NON-BLOCKING, independently,
on stronger evidence than either prior pass (accept-set matrix proving the accepted set is a strict
subset of a correct case-insensitive comparison's, so it cannot false-certify; exploit path hunted and
ruled out; all 0x110000 codepoints scanned for a fold that could smuggle non-hex onto a valid SHA).
So contamination did not change the answer, and the finding stands anyway — a correct answer reached
by a contaminated process still corrupts the process.

D-40: that same fresh seat looked outside its question and found a type confusion inside the exact
conjunction the exemption rests on. `step.get("exit_code") == 0` is True for JSON false, and
coder-mos1 added the float case. Verified by me on the real #2188 record: false and 0.0 both yield
exit 0 with exempted_steps 1 — the exemption GRANTED; "0" and null correctly block. Two of four
near-miss types satisfy a conjunction whose whole justification is that it is exactly scoped.

Consequence: I reported #1033 gate-ready at 033b2ffb (RR1-RR12 pass, review 69 APPROVED, CI #2193
success 9/9) and then had to hand Mos a finding that may disqualify what I had just certified. Better
that than defending the report. Disposition is Mos's; coder-mos1 escalated it to blocker unilaterally
and moved to push — held, because the author does not adjudicate their own PR and does not void a live
APPROVED review plus terminal-green CI by pushing. Head frozen, fix prepared and unpushed, ACKed.

Board doctrine now carries both rules: never relay a conclusion into an open review, and the author
never adjudicates their own blocker status.

And the shape holds: **RM-03 is the fix for the queue guard, so this — the first delivery through the
complete stack — is also the last one gated by a check that could not fail.**
### D-40 — a type confusion INSIDE the structural discriminator the whole design rests on
`step.get("exit_code") == 0` is **True for JSON `false`**, because Python `False == 0`. Reproduced twice
independently (fresh adjudicator, then the orchestrator): rewriting `ci-postgres`'s `exit_code` as JSON
`false` in the real `#2188` record yields **exit 0, `terminal-green`, `exempted_steps 1`, anomalies 0** —
**the exemption is granted on a boolean.**
**Why it is worth a finding despite being unreachable today.** Reachability requires the provider to emit
a boolean in an integer field; Woodpecker is Go with an `int` type and will not. It also only widens the
exemption to a step that ALREADY matches name, type, state and the exact ULID signature. But **"a failed
service step carrying `exit_code 0` under a SUCCESSFUL workflow" IS the structural discriminator this
entire exemption rests on** (see the RM-61 result above). A type confusion sitting inside that exact
conjunction earns a tracked owner even while unreachable — because RM-61's own doctrine is that
**correlates pass today and break the moment infrastructure shifts**, and the charter's rule is that a
documented gap with no owner becomes a permanent gap that reads as intentional.
**Disposition:** recommended NON-BLOCKING for #1033 and routed to Mos/the merge-gate as a recommendation,
explicitly **not** an orchestrator ruling. Fix: `isinstance(x, int) and not isinstance(x, bool)`.
**Provenance note worth keeping:** this was found by a seat dispatched to adjudicate something else
entirely (D-39's RR12 re-run), which looked outside its question and said so. The clean-context dispatch
paid for itself twice.
### D-39 — the ORCHESTRATOR contaminated an open independent review by stating its own conclusion
RR12 (case-sensitivity) was an **open registered check**. Before `rev-974` ruled, the orchestrator sent
it not merely the observation but **the conclusion**: _"my read is: acceptable, not a defect."_ `rev-974`
subsequently **downgraded an automated Codex review that had flagged RR12's false-block behaviour AS A
BLOCKER** to a bounded non-blocking note — in line with the orchestrator's framing.
**The bias was in the orchestrator's instrument, not the reviewer's diligence.** A subordinate is
agreeable by construction; handing one a conclusion on a live question and then receiving agreement is
the **confirmation-query failure** (`MISSION.md`, query-for-refutation) committed by the seat that
authored the query. The divergence instruction that accompanied it ("if your run disagrees that is a
finding") is **necessary but insufficient — it cannot undo having named the answer first.**
> **RULE ADOPTED — standing, fleet-wide (Mos, 2026-08-01).** A dispatcher (orchestrator included) MAY

> brief.**
**Re-adjudication (ordered by Mos, not optional given an automated reviewer had independently blocked).**
RR12 was re-run by a seat with **zero prior context** and no access to the orchestrator's framing, the
orchestrator's conclusion, or Codex's — given the artifact and the criterion only, and told explicitly
that either ruling was useful. **Result: NON-BLOCKING, reached independently, on stronger evidence than
either prior pass** — a full accept-set matrix showing exit 0 occurs on exactly one record string, so the
accepted set is a strict SUBSET of a correct case-insensitive comparison's, and **narrowing an accept-set
cannot introduce a false certification**. Exploit path hunted specifically and ruled out (the commit
anomaly is appended BEFORE `exemption_applies` is computed; no `re.IGNORECASE`; all 0x110000 codepoints
scanned for a fold that could smuggle non-hex onto a valid SHA).
`rev-974` separately volunteered that it had **already measured** the behaviour before the framing
arrived. That is recorded but **not leaned on** — it is self-report from the contaminated party. The
fresh seat is the actual check.
**So contamination did not change the answer — and the finding stands anyway.** A correct answer reached
by a contaminated process still corrupts the process. Note also the shape: **the automated reviewer
disagreed and the human seat that agreed with the orchestrator was the one that got deferred to.** That
asymmetry is the signal, not the outcome.
**Attaches to:** the dispatch-brief doctrine (every brief), and RM-58 (mechanical pre-dispatch reset) —
the re-adjudication was only trustworthy because the seat was **mechanically** fresh rather than asked to
be, which is D-4's lesson applied to independence rather than to context.
### D-38 — a gate that certified the right RECORD for the wrong COMMIT (and the AC set that could not see it)
**RM-61's terminal-green verifier reported the pipeline's commit and never bound it to the PR head.**
