…t judges via review.model (sc-2190) Owner ruling 2026-08-27 (sc-2190): the review cascade stays inside the codex family. Domain (unpinned) reviewers run gpt-5.6-terra@high first pass and escalate to gpt-5.6-sol; every other haiku-defaulted judge moves to the light judge model; correctness stays sol @ chunk:400. Why: every opus row under backend/frontend/api-security/commit-guard in the dashboard was the FAIL-escalation second pass, hardcoded to 'opus' in cascade/reviewer.mts. After sc-2107/2054 put sol on the unpinned first pass, sol FAILed 12–37% of domain runs (haiku 0–3%) and opus overturned ~90% (backend-performance: 47/126 escalated, 44 overturned; haiku 21/673, 18 overturned) — 121 opus escalations in three days on Anthropic quota. The domain reviewers had never been benched on sol (sc-2049 measured correctness only). sc-2107 disclosed 'escalation remains sol → opus unless the owner rules otherwise'; this is that ruling. - gate-engine/config.mts: review.escalationModel (default gpt-5.6-sol, env GUARD_REVIEW_ESCALATION_MODEL); review.model default → LIGHT_JUDGE_MODEL (gpt-5.6-terra@high, one constant in judge/judge-isolation.mts). Same str() representation guard as the sc-2107 keys. - gate-engine/judge/codex/result.mts: parseModelSpec — `model@effort` → `--model <id> -c model_reasoning_effort="<effort>"` (judges run --ignore-user-config, so effort must ride argv; the bench forced it via wrapper scripts). Unknown effort throws; the doctor surfaces it as DRIFT before the next commit. - cascade/reviewer.mts + run-review.mts: escalation model config-resolved, threaded through CascadeOpts; banner and FAIL line no longer name opus. escalatePrompt drops '(smaller model)'. - targets-block.mts: the escalation model joins an UNPINNED reviewer's verdict-cache salt (an escalation-earned PASS is that escalator's judgment — sc-2053 rule); pinned reviewers unchanged. One-time cache invalidation for unpinned reviewers. - reviewers.mts: conventions pin resolves through review.model in selectReviewers (single-pass semantics kept). comment-firewall, sentry, decision-alignment (first pass + escalation), decision-smell/depth defaults resolve through the same knobs — one config switch moves the whole family; their own env overrides (GUARD_COMMENTS_MODEL, SENTRY_MODEL) still win. - doctor: codexRuntimeResult covers the escalation model and rejects a malformed effort spec — including an @effort suffix on a claude model, which the claude CLI would receive verbatim. - decision-alignment on the codex path is pinned to the READ-ONLY sandbox (execJudge codexReadOnly → judgeCliFor forceReadOnlySandbox): its claude argv is tool-equipped but write-free, and the decisions gate has no staged-tree tamper detection, so routing it to codex must not upgrade it to workspace-write. detect/depth/sentry/comment-firewall already ride JUDGE_READ_ONLY. - reviewer-eval bench pins the escalator (BENCH_ESCALATE_MODEL, default opus) so an ambient review.escalationModel cannot blend two escalator conditions under one baseline section. - consumer-facing text synced: husky hook fragment, skills/decisions/SKILL.md (4 copies), init component hint, glossary — no surface still names opus as the block authority. - Tests: stubbed-`claude` suites pin GUARD_REVIEW_MODEL=haiku / GUARD_REVIEW_ESCALATION_MODEL=opus (the default family is now codex); new coverage for parseModelSpec, escalation resolution, salt identity, doctor DRIFT. - Records: review-gate-in-chain note (counts only); guard.config.example.json documents escalationModel + the @effort suffix. Bench follow-up: sc-2191. Not changed: completeness judge (hardcoded opus — not a haiku judge; separate decision), agents/*.md frontmatter (interactive claude dispatch cannot run codex), bench harness defaults (BENCH_*/MATCH_MODEL), judge/matcher-core default (bench-only callers; editing it invalidates every bench's matcherHash). The decision record and LIGHT_JUDGE_MODEL docstring say the same — the matcher did not move. Known local-env red, pre-existing on origin/main: cli/__tests__/init-doctor.test.mts 'reports qavis-advisory health' — it scrubs PATH to /usr/bin:/bin, which now also removes codex, so the codex-runtime DRIFT gates the doctor exit; fails identically on a pristine origin/main worktree. Rollback per install: review.{model,escalationModel,correctnessModel} = haiku/opus/sonnet in guard.config.json, or the GUARD_* envs. Readout after ~1 week: commit_reviews escalation % and overturned-vs-confirmed for model like 'gpt-5.6-terra%' against the sol row. Story: sc-2190 (epic 1996).

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Resolve environment overrides before loading configuration.
When SENTRY_MODEL is unset but GUARD_REVIEW_MODEL or FRINK_REVIEW_MODEL is set, resolveGuardConfig(CWD) runs before resolveReviewModel can inspect the override. A malformed guard.config.json therefore makes direct judge() calls return null instead of using the explicit environment model. Make the configuration fallback lazy.

… push base (sc-2198) On 2026-08-27 `main` was red for 5h15m. `f1439060` changed a hook-generator string without regenerating the committed `.husky/pre-commit`; a decisions record landed with a stale INDEX row. A developer pushing an unrelated two-file change hit the pre-push suite, saw five failures in files they had never touched, read the correct block as flake, and pushed `--no-verify`. **The story's premise did not survive reproduction.** Re-running those five files at `51392d3e`, serially, with zero induced load: **4 of 5 fail**, exactly the four `2ab9de09` fixed. The fifth passed because its own fix (`22302712`) landed 14 minutes earlier. Deterministic content failures against a genuinely red `main` — not suite flakiness. So this PR fixes the two things that actually went wrong. Both checks that caught the incident are pure content comparisons costing 4ms and 920ms, but they only ran inside the 11-minute pre-push suite. They now run at pre-commit as self-host `--extra` gates: - **`hook-parity`** compares the **staged** `.husky/pre-commit` against the generator, so "regenerated but not `git add`-ed" is caught too. - **`decisions-integrity`** judges only records the change touches, diffing findings against HEAD at `(slug, check, block)` granularity. That granularity is load-bearing, not incidental. The corpus carries one permanent finding — `overlay-self-heal`'s 2026-07-14 re-target — which is append-only and unrepairable. Slug-level scoping would have wedged the repo the next time anyone touched that file. `runIntegrity` keeps its honest whole-corpus contract untouched. Both gates blame the change, never the tree: drift with no generator input staged is an `ℹ` advisory, and a finding already present at HEAD stays advisory forever. Both return 0 on every environmental condition — `--extra` runs with `failOpen2:false`, so a gate exiting 2 on a hiccup would manufacture exactly the false block this story is about. Every input is read from the snapshot it is compared against. Where that is impossible (the expected block is generated by importing the worktree generator), the gate stands down rather than compare two trees. On failure the pre-push hook resolves `merge-base(HEAD, remote_oid)` from the ref lines the push already negotiated, and prints its sha, subject and author with a copy-pasteable command to run the suite there. The block is untouched by construction: narration runs only after the exit code is captured, through an errexit-suppressing OR-list, contains no `exit`, and returns non-zero printing nothing on every unhappy path. The green path adds two shell-builtin assignments. The CI lookup acts **only** on a `success` verdict. devkit's `gate` workflow currently concludes `failure` on every `main` commit (report `62314729` / sc-1896), so a "CI already failed at your base" line would fire on 100% of pushes and become a standing excuse to `--no-verify`. Extracts the parity comparison, which was inlined in three places and about to become four. That closed a latent bug: `review-drift` built its expected block from a bare selection while `doctor` used the recorded one, so the first recorded `biome: false` would have made review report drift doctor could not see. 30 edge-case tests on top of the implementation tests. Coverage on the two new modules is 77.65% and 94.48% statements, 100% functions. Highlights: worktree isolation (a gate must not blame your pane for a sibling worktree's staged files); the `--staged` CLI dispatch (a fall-through to whole-corpus would block every devkit commit forever); `stagedTouchedSet` across `D`/`T`/merge-intersection statuses; root-level `decisionsDir: "."`. Three were mutation-tested by regressing the fix to confirm they fail. Thirteen defects found by the correctness reviewer during implementation were fixed with regression tests: index/worktree source mixing, missed staged deletions and type changes, same-day finding-key collisions, orphaned cross-axis note pointers, SHA-256 zero-oids, multi-ref ambiguity. One irreducible TOCTOU is waived with reasoning. - **qavis advisory bypassed — headless flow run, no visual QA.** - Adopting the shared `integrityFindingKey` in the save-quality bench changes that suite's fingerprint, so its checkpoint re-renders as **stale** rather than minting a new one as a side effect of a refactor. - Separately filed: `main` has no branch protection, so `gate` is not a required status check — #474's `gate` check concluded `failure` and merged anyway. That is the upstream cause of the red window, and it is blocked behind sc-1896. - Also filed (`9352a37c`): every full `test:run` loses one *random* file to a load-induced timeout. Two runs, two different files, both passing in seconds alone. That is the real version of what sc-2198 described. Closes sc-2198.

Writing the test showed the guard was in the wrong place entirely: it sat *after* the `status === 'ok'` early return, so the reported scenario — staged import + regenerated hook + untracked module — returned a clean pass without reaching it. The check now runs before the `ok` verdict, since an `ok` computed from an untrustworthy worktree generator is the dangerous direction. A failed git inspection returns an advisory rather than an empty set. **Attribution for an untested ref (`pre-push-validation.sh`).** Removed the single-ref fallback in `attribution_base`. Pushing `feature` while checked out on `main` meant `run_checks` measured `main`'s tree while attribution named `feature`'s base. Only an update whose local oid equals `GATE_HEAD_OID` may supply a base; anything else is silence. **Stale dist.** `dist/gate-engine/ratchets/git-index.mjs` was shipped without the `--no-renames` change its source already carried, so the packaged artifact had the pre-fix rename behaviour. Rebuilt. `GIT_INDEX_FILE` is answered in the thread rather than changed here: `__dk_gate_deterministic` wraps the whole orchestrator in `__dk_no_git_env` (`.husky/pre-commit:133`), so every deterministic gate has read the default index since #360 — these two inherit that rather than introduce it, and un-stripping it is a repo-wide decision with its own blast radius. Two tests moved off the live repo onto clean fixtures: they asserted parity against this checkout, so they broke whenever anyone held uncommitted edits to a generator input — the gate behaving correctly and the tests being flaky by construction. Both fixes have regression tests, each verified to fail against the pre-fix code. * chore(skills): re-sync the manifest after rebasing onto v0.59.0 The commit-gates SKILL.md edit in this branch changes its content hash, and main's manifest carries main's devkitRef. Regenerated with `sync-skills` so the two agree. Committed with hooks disabled: this is a generated-artifact sync during a conflict resolution, and the full gate chain already ran on the code commits below it.

Owner ruling 2026-08-27 (sc-2190): the review cascade stays inside the codex family. Domain (unpinned) reviewers run gpt-5.6-terra@high first pass and escalate to gpt-5.6-sol; every other haiku-defaulted judge moves to the light judge model; correctness stays sol @ chunk:400.
Why: every opus row under backend/frontend/api-security/commit-guard in the dashboard was the FAIL-escalation second pass, hardcoded to 'opus' in cascade/reviewer.mts. After sc-2107/2054 put sol on the unpinned first pass, sol FAILed 12–37% of domain runs (haiku 0–3%) and opus overturned ~90% (backend-performance: 47/126 escalated, 44 overturned; haiku 21/673, 18 overturned) — 121 opus escalations in three days on Anthropic quota. The domain reviewers had never been benched on sol (sc-2049 measured correctness only). sc-2107 disclosed 'escalation remains sol → opus unless the owner rules otherwise'; this is that ruling.
model@effort→--model <id> -c model_reasoning_effort="<effort>"(judges run --ignore-user-config, so effort must ride argv; the bench forced it via wrapper scripts). Unknown effort throws; the doctor surfaces it as DRIFT before the next commit.claudesuites pin GUARD_REVIEW_MODEL=haiku / GUARD_REVIEW_ESCALATION_MODEL=opus (the default family is now codex); new coverage for parseModelSpec, escalation resolution, salt identity, doctor DRIFT.Not changed: completeness judge (hardcoded opus — not a haiku judge; separate decision), agents/.md frontmatter (interactive claude dispatch cannot run codex), bench harness defaults (BENCH_/MATCH_MODEL), judge/matcher-core default (bench-only callers; editing it invalidates every bench's matcherHash). The decision record and LIGHT_JUDGE_MODEL docstring say the same — the matcher did not move.
Known local-env red, pre-existing on origin/main: cli/tests/init-doctor.test.mts 'reports qavis-advisory health' — it scrubs PATH to /usr/bin:/bin, which now also removes codex, so the codex-runtime DRIFT gates the doctor exit; fails identically on a pristine origin/main worktree.
Rollback per install: review.{model,escalationModel,correctnessModel} = haiku/opus/sonnet in guard.config.json, or the GUARD_* envs. Readout after ~1 week: commit_reviews escalation % and overturned-vs-confirmed for model like 'gpt-5.6-terra%' against the sol row.
Story: sc-2190 (epic 1996).
