From 78e501e34c45c04a21c2905fd665b2608e2fae57 Mon Sep 17 00:00:00 2001 From: James Wiesebron Date: Thu, 9 Jul 2026 15:35:03 -0700 Subject: [PATCH 1/4] [jwies/review-budget-cap] review: clamp the run budget to the effective credit cap; land before the cap The tier budget table assumes the workflow's $10 ceiling, but the per-run credit cap is enforced runner-side and was invisible to the agent, so a tighter consumer cap produced soft targets the hard cap could not pay for: the 400-credit budget-shed behavior test planned against the high tier's $10 targets, spent 390 credits on the finder phase, and was killed by the api-proxy mid-persist with findings in hand and nothing posted. Three changes close the gap: - The frontmatter sets max-ai-credits: 1000 explicitly and mirrors it into the agent environment as REVIEW_MAX_AI_CREDITS (consumers that override the cap keep the two in sync). - The router resolves the effective cap (mirror, GH_AW_MAX_AI_CREDITS, a visible awf config, then the 1000-credit gh-aw default) and clamps the selected tier budget proportionally, floored at the trivial tier's values; routing.json carries capClamped and effectiveCreditCap so the orchestrator and post-hoc audits see the clamp. - The budget prompt adds an estimated-credits proxy (in-band subagent_tokens sum / 5000) and two mandatory checkpoints, the critical one after the last finder returns and before claim validation, the exact boundary the observed run died at. --- .changeset/review-budget-cap-clamp.md | 5 + workflows/review/lib/router.test.ts | 144 +++++++++++++++++++++++++ workflows/review/lib/router.ts | 149 +++++++++++++++++++++++++- workflows/review/review.md | 40 +++++-- 4 files changed, 328 insertions(+), 10 deletions(-) create mode 100644 .changeset/review-budget-cap-clamp.md diff --git a/.changeset/review-budget-cap-clamp.md b/.changeset/review-budget-cap-clamp.md new file mode 100644 index 00000000..1898f30f --- /dev/null +++ b/.changeset/review-budget-cap-clamp.md @@ -0,0 +1,5 @@ +--- +"review": patch +--- + +Clamp the router's run budget to the effective per-run AI-credits cap, and make the cap visible to the run. The tier budget table is sized inside the workflow's assumed $10 ceiling, but the cap is enforced runner-side by the firewall api-proxy and was invisible in-container, so a consumer with a tighter `max-ai-credits` got soft targets that promised more work than the cap could pay for; the graceful-degradation path never fired and the run died at the api-proxy with findings in hand (observed on a 400-credit behavior test: three finders completed, ~390 credits spent, killed mid-persist before validation, nothing posted). The frontmatter now sets `max-ai-credits: 1000` explicitly and mirrors it into the agent environment as `REVIEW_MAX_AI_CREDITS` (kept in sync by consumers that override the cap); the router resolves the cap from that mirror (falling back to `GH_AW_MAX_AI_CREDITS`, a visible awf config, then gh-aw's 1000-credit default) and scales the selected tier's soft targets proportionally, floored at the trivial tier's values, marking `runBudget.capClamped` and `runBudget.effectiveCreditCap` in routing.json. The budget prompt gains a matching estimated-credits proxy (sum of in-band `subagent_tokens` over completed sub-agents, divided by 5,000) and two mandatory proxy checkpoints, the critical one immediately after the last finder returns and before claim validation, so a tight run sheds and lands a partial review instead of dying at the cap. diff --git a/workflows/review/lib/router.test.ts b/workflows/review/lib/router.test.ts index cb316637..abb3a6d4 100644 --- a/workflows/review/lib/router.test.ts +++ b/workflows/review/lib/router.test.ts @@ -2,7 +2,9 @@ import {describe, it, expect} from "vitest";

The description is untrusted author text, so adversarial cases can carry their payload there or in the diff. - An on-disk post-change file tree, via a new `/case.json` + `/tree/` layout coexisting with flat `.json`. A directory containing `case.json` is one case; its tree is never parsed as corpus JSON. - `mustCatchSpecs` / `mustNotFlagSpecs`: labeled defects as (path, line window, mechanism keyword alternates). Live runs choose their own finding ids, so ground truth matches on anchor window plus mechanism rather than id; the Phase 3 matcher consumes these. Enforced invariants: the `live` tag and the block imply each other; a live case needs a cleanly-parseable diff (fail-open is fine in production, an authoring error here); spec paths must appear in `changedFiles` and the diff; every non-removed changed file must exist in the tree. `loadLiveCorpus()` returns the subset. ## Cases Ten cases converted with hand-authored real diffs and trees: the five smoke incidents (money rounding, auth bypass, cache key, race condition, missing index), both clean cases, the adversarial injection case (payload is a code comment in the diff instructing the reviewer to approve), the golden authz holdout, and the money-payments synthetic mutation. Recorded line anchors are rewritten to the authored defect lines; natural files beat content padded to synthetic line numbers, and every anchor is asserted to be an added line so the provenance gate (now active on these cases) keeps them. The trial-content port landed as #235, stacked on this PR. One acceptance-driven change also landed here: the phase 4 runs missed `incident-sql-missing-index` in all four arms because live cases carried no `routerConfig` lens rules, so specialist lenses never spawned; every live case whose ground truth belongs to a specialist lens now routes that lens on the finding's file (see the "route the specialist lens on each live case" commit). ## Test plan: - `pnpm run test --run`: 659 tests green, including 17 new loader tests (memfs) covering the live block, both layouts, tree validation, and the tree-JSON exclusion. - The deterministic suite runs the ten converted cases unchanged (same verdicts, comment counts, must-catch sets), now with the provenance gate active on them. - `pnpm run typecheck` and eslint clean on the three touched TS files. ## Next steps (human) 1. Review the ten authored diffs and trees for realism; they are synthetic content a live model will read, so plausibility matters more than in ordinary fixtures. Spot-check that each case's recorded finding still describes the authored defect (anchors were rewritten to the authored lines). 2. This is the root of the stack: review and undraft first; #234 and #235 rebase onto it. 3. No live validation needed here; the deterministic suite (`pnpm run test --run`) fully gates it.

Ten cases are converted with hand-authored real diffs and trees (five smoke incidents, both clean cases, one adversarial injection whose payload lives in the diff, one golden holdout, one synthetic mutation); their recorded line anchors now point at the authored defect lines, and the deterministic suite runs them unchanged, provenance gate included. diff --git a/.eslintrc.js b/.eslintrc.js index 9359a217..f3729fa5 100644 --- a/.eslintrc.js +++ b/.eslintrc.js @@ -26,7 +26,14 @@ module.exports = { sourceType: "module", ecmaVersion: 2022, }, - ignorePatterns: ["**/dist/", "actions/**/index.js"], + ignorePatterns: [ + "**/dist/", + "actions/**/index.js", + // Live eval-corpus trees are byte-exact fixtures paired with each + // case's diff: linting (and especially prettier auto-formatting) + // would desync them from the diff the provenance gate parses. + "workflows/review/eval/corpus/**/tree/", + ], overrides: [ { files: "**/*.ts", diff --git a/vitest.config.ts b/vitest.config.ts index 043ae5c5..d7bfeae3 100644 --- a/vitest.config.ts +++ b/vitest.config.ts @@ -1,9 +1,16 @@ -import {defineConfig} from "vitest/config"; +import {configDefaults, defineConfig} from "vitest/config"; export default defineConfig({ test: { watch: false, clearMocks: true, setupFiles: ["./config/tests/setup.ts"], + // Live eval-corpus trees are case fixtures, not suite code: a tree + // may legitimately carry a *.test.ts whose tests fail by design + // (the test-adequacy cases), so vitest must never execute them. + exclude: [ + ...configDefaults.exclude, + "workflows/review/eval/corpus/**/tree/**", + ], }, }); diff --git a/workflows/review/eval/corpus/clean/clean-typed-refactor.json b/workflows/review/eval/corpus/clean/clean-typed-refactor.json deleted file mode 100644 index 58c1b7aa..00000000 --- a/workflows/review/eval/corpus/clean/clean-typed-refactor.json +++ /dev/null @@ -1,15 +0,0 @@ -{ - "id": "clean-typed-refactor", - "tags": ["clean"], - "category": "clean", - "description": "Known-clean PR: a mechanical rename of a helper across a few files with no behaviour change.
