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.
