Шаг слияния конвейера считает patch-id материала и кандидата через
`git diff --full-index`, когда `dev` сдвинулся за время ревью. Дифф задачи,
пересобирающей бандл, несёт три копии `houseplan-card.js` — у #594 это
7 103 616 байт. `sh()` не задавал `maxBuffer`, умолчание `spawnSync` — 1 МиБ,
и процесс убивался по ENOBUFS на 1 027 868 байтах.
Вторая половина дефекта прятала первую: `r.error` нигде не читался, а
`status: r.status ?? 1` выдавало `null` за «git вернул 1». `must()` брал
`r.stderr || r.stdout`, stderr был пуст — и в issue уезжало
«Слияние не выполнено: diff: <огрызок диффа>». Огрызок выглядит осмысленным
и уводит разбор в сторону.
Путь исполняется только при сдвинувшемся `dev`, поэтому дефект дремал. Но
конвейер сам пушит в `dev` документ ревью на каждом раунде, так что
`devMoved` — норма, а не исключение.
Что изменено:
- `MAX_COMMAND_OUTPUT_BYTES` (256 МиБ) и явный `maxBuffer` в `sh()`;
- `sh()` называет сбой запуска в `stderr` результата вместо молчания;
- `sh()` экспортирован, у обоих пунктов есть исполнимый свидетель;
- мутант `merge-candidate-truncates-the-candidate-diff` возвращает 1 МиБ.

The candidate is the branch tip, which already carries the round's
CODE-REVIEW-N-rK.md; the material the reviewer read does not. With
docs/reviews in the diff the two patch-ids never matched once dev had
moved, so every green candidate went back to review whenever another
task published its own document in the meantime — #514 looped twice on
09.09 and #508 only merged when dev happened to stand still. The
patch-id now excludes docs/reviews, exactly like `reviewedFresh` next to
it; a real change of the patch under rebase still returns the task.

Code review r2 (M1): the cancelled-run filter in merge-candidate's
waitValidate had no test or mutant — every test replaced ops.waitValidate
with a fake. realOps now takes an injectable `exec` (default: the same
spawnSync wrapper) so the real implementation runs against scripted
`gh run list` answers: a cancelled dispatch is skipped and its
replacement followed; a lone cancelled run ends in `missing`, never red.

Validate ran the three "Мутанты по диффу" shards on every push of every
branch: 48 of 56 job-hours on 08–09.09, most of them cancelled by the
next push. Mutants now run when asked — pull requests, the nightly
schedule, a push carrying a `Release:` trailer, or a dispatch with
`mutants=true` (classify-changes.mjs → `mutants_requested`); an ordinary
push runs the light checks only.
The proof moves to where it is consumed. process.yml gets a gate after
the #499 reuse step: on the code stage it looks for a dispatch Validate
run on the exact material SHA whose mutant jobs executed and passed
(scripts/validate-gate.mjs); none → it dispatches one and waits; red or
missing → the task goes back S7→S6 with the run link and the review
cycle is not spent. Spec stage and the reuse fast-path skip the gate
(`proceed=true`); all later steps branch on `proceed` in place of the
old conflict conjunct only. merge-candidate.mjs dispatches Validate on
the pushed candidate and waits for that dispatch run.
PROCESS.md/AGENTS.md: review does not start on red code; one handoff —
one push.

scripts/merge-candidate.mjs owns the review pipeline's merge: when dev
moved during review, the rebased candidate is pushed to the issue branch,
its diff is compared to the reviewed one by patch-id, Validate on that SHA
is awaited, and only then dev is advanced with --force-with-lease on the
base the candidate was built on — a rejected lease restarts, at most three
times. Every non-merge outcome moves the label with a comment, so the
"label always changes" invariant holds. nightly.yml now finds the Validate
run it dispatched and inherits its conclusion. Three mutants guard this.
