From 2d746ac4917ace88d9ed4268da9baf118cbbde0c Mon Sep 17 00:00:00 2001 From: James Wiesebron Date: Thu, 9 Jul 2026 12:47:33 -0700 Subject: [PATCH 01/19] [jwbron/live-eval-corpus] review: live-enabled corpus format and ten live cases Phase 1 of the live A/B eval plan (Khan/actions#232). The corpus gains an opt-in live block carrying what a real model run needs and the deterministic replay does not: - prContext (PR title/description/author/base; the description is untrusted author text, so an adversarial case can carry its payload there or in the diff), - a post-change file tree on disk next to the case, via a new /case.json + /tree/ layout that coexists with flat .json (a directory containing case.json is one case; its tree is never parsed as corpus JSON), and - labeled defect specs (mustCatchSpecs / mustNotFlagSpecs: path, line window, mechanism keyword alternates). Live runs choose their own finding ids, so ground truth matches on anchor window + mechanism rather than id. The loader enforces the invariants: the live tag and the live block imply each other, a live case needs a cleanly-parseable diff, spec paths must appear in changedFiles and the diff, and every non-removed changed file must exist in the tree. loadLiveCorpus() returns the subset. The live half lives in corpus/live.ts; loader.ts re-exports it as the single public surface. Ten cases are converted with hand-authored real diffs and trees: five smoke incidents, both clean cases, one adversarial injection whose payload is a code comment in the diff, one golden holdout, and one synthetic mutation. Their recorded line anchors are rewritten to the authored defect lines (natural files beat content padded to synthetic line numbers), which activates the provenance gate on these cases in the deterministic suite; all expectations hold unchanged. --- .changeset/review-live-corpus-format.md | 5 + .../corpus/clean/clean-typed-refactor.json | 15 - .../clean/clean-typed-refactor/case.json | 33

It takes the markdown as a string with no fs access, because the baseline arm of an A/B reads the merge-base review.md via git show. Parsing is strict; a malformed or model-less section throws listing every problem, since a silently dropped agent would skew an eval arm without failing it. An integration test extracts the real review.md (21 agents) and pins the staging-root reference so a future rename fails a test instead of silently staging nothing. live-stage.ts materializes the production staging layout for one live-enabled corpus case: pr-context.json (review.md Step 1's shape, synthetic identity fields), full.diff / pr.diff / full-stripped.diff (all the case diff; corpus diffs carry no generated files and no pattern-triage pass runs), files.json + review-files.json with the hasPatch cross-check derived from the diff parse, provenance.json, routing.json from the deterministic router, an out/ directory, and the post-change checkout copied from the case tree. rewriteAgentPrompt swaps the production staging root for the staged context dir.

Roster: the default finders (correctness-reviewer, skill-auditor) plus the router's lensesToSpawn; no pattern-triage or thread-reconciler in eval. It maps all three sub-agent output contracts into the shapes the deterministic runner consumes: label-shape findings (correctness lens, or conventions for the skill-auditor so labelForFinding reproduces the best-practice variants; confidence defaulted to 0.7 per the production claims rule), structured-schema lens findings validated as-is, and the validator's {claims: [...]} verdicts into CaseVerification[]. It stages claims.json for the validator, resolves {{#runtime-import}} directives against the case tree (a case opts into a skills index by carrying the file), retries once on malformed output with the rejection fed back, keeps partial results when an agent fails twice, prefixes colliding finding ids, and reports per-agent cost/turns/wall-clock. live-runner.ts is the one module that touches a real model runtime: an Agent SDK query() per dispatch with Read/Grep/Glob only, cwd pinned to the staged checkout, the agent's pinned model, and hard turn and wall-clock caps; plus the CLI smoke entry (tsx live-runner.ts --case , requires ANTHROPIC_API_KEY). The investigation-cap CLI the prompts reference is not staged; its own denied-budget fallback applies. Adds @anthropic-ai/claude-agent-sdk as a dev dependency. --- .changeset/review-live-producer-staging.md | 2 +- package.json | 1 + pnpm-lock.yaml | 660 ++++++++++++++++++++ workflows/review/eval/live-producer.test.ts | 398 ++++++++++++ workflows/review/eval/live-producer.ts | 591 ++++++++++++++++++ workflows/review/eval/live-runner.ts | 158 +++++ 6 files changed, 1809 insertions(+), 1 deletion(-) create mode 100644 workflows/review/eval/live-producer.test.ts create mode 100644 workflows/review/eval/live-producer.ts create mode 100644 workflows/review/eval/live-runner.ts diff --git a/.changeset/review-live-producer-staging.md b/.changeset/review-live-producer-staging.md index 06a3b138..7cf3c638 100644 --- a/.changeset/review-live-producer-staging.md +++ b/.changeset/review-live-producer-staging.md @@ -2,4 +2,4 @@ "review": minor --- -Live eval arm, phases 2a and 2b (live A/B plan): sub-agent prompt extraction and case staging. `eval/agent-extract.ts` parses `review.md`'s `## agent:` sections into name/description/model/prompt as pure data (string in, no fs), so an A/B can extract the baseline arm from a `git show` of the merge-base; parsing is strict and lists every malformed section at once, and an integration test runs it over the real `review.md`. `eval/live-stage.ts` materializes the production `/tmp/gh-aw/review/` staging layout for a live-enabled corpus case (pr-context.json, full/pr/full-stripped diffs, files.json with hasPatch, review-files.json, provenance.json, routing.json, out/, and the post-change checkout) and rewrites extracted prompts to point at it, behind an injected-fs seam.

lenses, the claim-validator's three-state verdicts) into the exact `RecordedFinding`/`CaseVerification` shapes the deterministic runner consumes, stages `claims.json`, resolves `{{#runtime-import}}` directives from the case tree, retries once on malformed output, keeps partial results on agent failure, and accounts per-agent cost. `eval/live-runner.ts` is the one SDK-backed runner (Claude Agent SDK; Read/Grep/Glob only, cwd pinned to the staged checkout, hard turn and wall-clock caps) plus a CLI smoke entry (`pnpm dlx tsx workflows/review/eval/live-runner.ts --case `, requires

An injected fallback arbiter (hard-capped, same-file only, recorded as via: fallback for audit) can rescue recall on vague prose; false flags are decided by the deterministic rule alone. computeLiveMetrics aggregates recall, verdict agreement, clean false-flag (including a clean case that blocks), and noise. live-ab.ts is the arm orchestrator and CLI: baseline review.md from git show , candidate from the working tree, both arms over the same live corpus with everything else (corpus, lib, runner, metrics, judge) from the candidate, per the plan's settled decision to isolate the model seam. Each arm runs under half the --max-usd budget with sticky exhaustion: once spend plus the running per-case average crosses the cap, remaining cases are recorded skipped and the report still emits. Spec-level regressions are diffed only over cases both arms scored. Judge scoring reuses the pinned judge (quality aggregates only; judge-vs-ground-truth disagreement keys on recorded ids a live arm does not use); the fetch model moves to judge-live-model.ts and live-judge.ts now imports it. runner.ts gains an optional RunOptions.validation override so a live validator's output replaces the recorded block. Report-only except the standing rule: adversarial-injection failures on the candidate arm exit non-zero. --- .changeset/review-live-ab-runner.md | 5 + workflows/review/eval/judge-live-model.ts | 73 ++++ workflows/review/eval/live-ab.test.ts | 252 +++++++++++ workflows/review/eval/live-ab.ts | 488 ++++++++++++++++++++++ workflows/review/eval/live-judge.ts | 72 +--- workflows/review/eval/live-match.test.ts | 276 ++++++++++++ workflows/review/eval/live-match.ts | 297 +++++++++++++ workflows/review/eval/runner.ts | 18 +- 8 files changed, 1411 insertions(+), 70 deletions(-) create mode 100644 .changeset/review-live-ab-runner.md create mode 100644 workflows/review/eval/judge-live-model.ts create mode 100644 workflows/review/eval/live-ab.test.ts create mode 100644 workflows/review/eval/live-ab.ts create mode 100644 workflows/review/eval/live-match.test.ts create mode 100644 workflows/review/eval/live-match.ts diff --git a/.changeset/review-live-ab-runner.md b/.changeset/review-live-ab-runner.md new file mode 100644 index 00000000..f716657c --- /dev/null +++ b/.changeset/review-live-ab-runner.md @@ -0,0 +1,5 @@ +--- +"review": minor +--- + +The live A/B runner (live A/B plan, phase 3). `eval/live-match.ts` maps a run's posted candidates onto a live case's labeled defect specs (deterministic path/window/mechanism rule first, then an injected hard-capped fallback arbiter whose matches are recorded for audit) and aggregates live metrics: must-catch recall, verdict agreement, clean false-flag, and noise. `eval/live-ab.ts` runs the model sub-agents from two review.md versions (the merge-base baseline via `git show`, the working-tree candidate) over the same live corpus, each arm under half a hard USD budget with sticky stop-and-report-skips semantics, replays each live result through the deterministic pipeline (`runner.ts` gains a `validation` override on `RunOptions` so a live validator's output replaces the recorded block), diffs spec-level regressions over the cases both arms scored, judges both arms' comments with the pinned judge (quality aggregates only; extracted to `eval/judge-live-model.ts`, now shared with `live-judge.ts`), and emits a JSON report plus a markdown table (also appended to GITHUB_STEP_SUMMARY).

Measured basis: + roughly $7-10 per workflow-arm run; total is arms x (1 + lifecycle + pushes), hosted-arm runs billed separately by the app. Print the + projection and get an explicit yes before creating any PR. + +## Step 1: isolated arm PRs + +For each arm, create `trial//` from the seeded branch and open a +PR in the consumer repo (title prefixed `[reviewer-trial]`, body stating it +is a trial and will be closed unmerged). One PR per arm; never point two arms +at the same PR, or their comments contaminate each other. + +Per-arm trigger setup: + +- `repo-default`: nothing extra; the repo's reviewer triggers normally. +- `workflow @ ref`: commit the compiled workflow for that ref onto the arm + branch. **Give it a workflow name distinct from the repo's own reviewer + and from every other arm**: same-named gh-aw workflows share a per-PR + concurrency group and silently cancel each other (this ate a run in the + original trial). Then suppress the repo's default reviewer on this PR via + its documented opt-out (`skip-ai-review` label in Khan repos), so exactly + one reviewer runs per PR. +- `hosted`: suppress the default reviewer the same way, then trigger with an + `@claude review` comment. + +Draft PRs generally do not trigger reviewers; open the PRs ready-for-review. + +## Step 2: run and collect + +For each arm: trigger, then watch to completion (`gh run watch` / +`gh pr checks`). Collect, per run: + +- The posted review: verdict, every inline comment (path, line, body), and + the review body (`gh api` on the PR's reviews and review comments). +- Run artifacts when the arm is the shared workflow (findings, claims, + verdict JSONs): `gh run download`. Tolerate the known gh-aw staging-path + artifact bug (an ERR_VALIDATION annotation; the artifacts still upload). +- Cost and wall clock: billed AI credits from the run summary, run duration + from `gh run view`. Hosted-arm cost is app-billed; record it as opaque + unless the operator supplies it. + +Record everything into a working directory as you go; a trial that loses its +transcripts cannot be scored or exported. + +## Step 3: lifecycle (when the plan includes it) + +Push the operator's push-2 content to EVERY arm branch (identical commits), +let each arm re-review, and collect again; repeat for push-3. Score each push +separately: re-review behavior (thread resolution, duplicate suppression, +scoping to new hunks) is half the point of the lifecycle. + +## Step 4: score + +Match each arm's posted comments against the defect table, per push: + +- Deterministic first: same path, line within (or overlapping) the window, + and any mechanism alternate matching the comment text, case-insensitively. + This mirrors `workflows/review/eval/live-match.ts`; one comment satisfies + at most one seed. +- Ambiguous leftovers: judge manually, and mark judged matches in the report + so a reader can audit them. +- Non-defect traps: a comment matching a trap row is a false flag; silence + on a trap is correct suppression and counts FOR the arm. + +Produce the #40678 report shape: a headline table (seeds caught, verdict, +comment count, cost, wall clock, per arm), a defect-by-defect table (one row +per seed, one column per arm), a lifecycle table when applicable, and a short +writeup naming where each margin came from. Report faithfully: misses, +wrong severities, and noise comments all go in, whichever arm they favor. + +## Step 5: export to the corpus + +Every trial compounds the corpus. Emit case skeletons in the live-enabled +format (`workflows/review/eval/corpus/`, layout `/case.json` + `tree/`; +format spec in `corpus/live.ts`): the seeded diff, the post-change tree, +`live.mustCatchSpecs` straight from the defect table, traps as +`mustNotFlagSpecs` on a clean case, and recorded findings taken from the +best arm's artifacts. + +**Sanitization gate**: if the consumer repo is private and the corpus repo +public (Khan/webapp into Khan/actions is exactly this), never copy code, +paths, or identifiers. Author structural rewrites that reproduce each +defect mechanism with generic naming, the way the #40678 seeds landed in +Khan/actions#235. When in doubt, rewrite. + +## Step 6: clean up + +Close every trial PR with a comment linking the report, delete the +`trial//*` branches, and confirm no temporary workflow file survived +onto a long-lived branch.
