From 89cc78afcafe619af1ace1bbcddef3d1533931b3 Mon Sep 17 00:00:00 2001 From: igerber Date: Mon, 20 Jul 2026 15:01:44 -0400 Subject: [PATCH 1/7] Plan-review eval harness + content-hash ExitPlanMode gate (workflow-eval step 1) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Builds the measurement infrastructure for the plan-review workflow family (the first target of the eval-per-workflow-surface program) and lands the purely mechanical gate fixes. The live review engine does not change. tools/plan-review-eval/ — five-arm harness over eval_core (verify-corpus / smoke / run / extract / compare / verdict): pinned-git-SHA control arm, candidate single+dual arms, Sonnet-5 and gpt-5.6-terra probe arms, all k=2. Pre-registered DECISION_RULE.md; neutral-severity extraction with blinded bundles whose bundle_id is the hash of the grader-visible bytes; mechanical verdict gates (GO / NO-GO / PARITY / UNDETERMINED) with protocol-violation labeling (NON-GATING) for rehearsal or subset runs. Campaign provenance is end-to-end: one immutable protocol snapshot per stage feeds both the recorded identity and execution; the identity covers the decision rule, configs, every candidate artifact, the control prompt, and EVERY Python source in the plan-review-eval and eval_core trees (walked, not hand-listed); stages gate at entry against the snapshot and re-check at exit with a fresh read; the protocol sha is stamped into extraction metadata and blinding.json and re-verified downstream; the blind mapping is recomputed at verdict, never trusted. The corpus loader enforces the manifest.schema.json type contract before dataclass construction, so a schema-invalid value (e.g. "must_catch": "false") can never flip a campaign gate through truthiness. Real plan corpora stay local-only (gitignored); one fabricated fixture case is committed for CI, smoke, and the dress rehearsal. .claude/hooks/check-plan-review.py replaces the sentinel-file gate: the ExitPlanMode hook now validates a plan_sha256 recorded in the review file's frontmatter against the CURRENT plan bytes — no sentinel, no mtime, no touch hack, no cross-worktree races. It fails closed on payload drift, missing tool_input, unreadable plans, malformed frontmatter, and path mismatches (realpath-normalized both sides). .claude/scripts/plan_snapshot.py provides the tested snapshot/persist/check/abort protocol the commands use: invocation-unique digest+nonce state tokens, recorded-digest certification (persist re-verifies the live plan against the reviewed snapshot), canonical-path-digest review filenames, and strict path ingress (absolute, no CR/LF, no whitespace edges). /review-plan and /revise-plan are thin wrappers over the helper; every check/snapshot call site requires confirming the helper's echoed plan_path (shared per-worktree ingress). The recorded threat model (DEFERRED.md): the gate prevents accidents, not local adversaries. Tests: hook decision table, snapshot protocol (incl. hostile-stem bash end-to-end), harness units (corpus contracts, hermetic pinned-SHA sourcing, arm schema, synthetic k=2 verdict tables, protocol-identity regressions), and command-contract scans. --- .claude/commands/review-plan.md | 125 +- .claude/commands/revise-plan.md | 102 +- .claude/hooks/check-plan-review.py | 253 +++ .claude/hooks/check-plan-review.sh | 117 -- .claude/hooks/test-check-plan-review.sh | 206 -- .claude/scripts/plan_snapshot.py | 376 ++++ .claude/settings.json | 2 +- .gitignore | 5 + CHANGELOG.md | 13 + CLAUDE.md | 64 +- DEFERRED.md | 1 + TODO.md | 2 + tests/test_command_contract.py | 79 +- tests/test_evals_runtime.py | 4 +- tests/test_plan_review_eval.py | 1656 +++++++++++++++++ tests/test_plan_review_hook.py | 298 +++ tests/test_plan_snapshot.py | 352 ++++ tools/eval_core/compare.py | 21 +- tools/eval_core/models.py | 8 + tools/eval_core/runner.py | 4 +- tools/plan-review-eval/DECISION_RULE.md | 149 ++ tools/plan-review-eval/README.md | 110 ++ tools/plan-review-eval/candidates/criteria.md | 79 + .../candidates/extraction_prompt.md | 41 + .../candidates/merge_verify.md | 64 + .../candidates/reviewer_prompt.md | 24 + tools/plan-review-eval/config/configs.json | 69 + .../corpus/fixture/fx-mini-plan/case.json | 35 + .../corpus/fixture/fx-mini-plan/plan.md | 24 + .../corpus/manifest.schema.json | 60 + .../plan_adapters/__init__.py | 6 + .../plan_adapters/corpus_loader.py | 263 +++ .../plan_adapters/criteria_source.py | 207 +++ .../plan_adapters/plan_reviewer.py | 459 +++++ .../plan_adapters/worktree.py | 131 ++ tools/plan-review-eval/run_eval.py | 1010 ++++++++++ tools/plan-review-eval/verdict.py | 440 +++++ .../reviewer-eval/adapters/codex_reviewer.py | 6 +- tools/reviewer-eval/adapters/corpus_loader.py | 2 +- tools/reviewer-eval/adapters/worktree.py | 55 +- 40 files changed, 6461 insertions(+), 461 deletions(-) create mode 100755 .claude/hooks/check-plan-review.py delete mode 100755 .claude/hooks/check-plan-review.sh delete mode 100644 .claude/hooks/test-check-plan-review.sh create mode 100644 .claude/scripts/plan_snapshot.py create mode 100644 tests/test_plan_review_eval.py create mode 100644 tests/test_plan_review_hook.py create mode 100644 tests/test_plan_snapshot.py create mode 100644 tools/plan-review-eval/DECISION_RULE.md create mode 100644 tools/plan-review-eval/README.md create mode 100644 tools/plan-review-eval/candidates/criteria.md create mode 100644 tools/plan-review-eval/candidates/extraction_prompt.md create mode 100644 tools/plan-review-eval/candidates/merge_verify.md create mode 100644 tools/plan-review-eval/candidates/reviewer_prompt.md create mode 100644 tools/plan-review-eval/config/configs.json create mode 100644 tools/plan-review-eval/corpus/fixture/fx-mini-plan/case.json create mode 100644 tools/plan-review-eval/corpus/fixture/fx-mini-plan/plan.md create mode 100644 tools/plan-review-eval/corpus/manifest.schema.json create mode 100644 tools/plan-review-eval/plan_adapters/__init__.py create mode 100644 tools/plan-review-eval/plan_adapters/corpus_loader.py create mode 100644 tools/plan-review-eval/plan_adapters/criteria_source.py create mode 100644 tools/plan-review-eval/plan_adapters/plan_reviewer.py create mode 100644 tools/plan-review-eval/plan_adapters/worktree.py create mode 100644 tools/plan-review-eval/run_eval.py create mode 100644 tools/plan-review-eval/verdict.py diff --git a/.claude/commands/review-plan.md b/.claude/commands/review-plan.md index 02ae2110d..71ef1da68 100644 --- a/.claude/commands/review-plan.md +++ b/.claude/commands/review-plan.md @@ -41,22 +41,50 @@ Options: ## Constraints -- **Read-only for project files**: Do NOT create, edit, or delete any project files (source code, tests, documentation, configuration).

Each grader copies the bundle's + embedded **Bundle ID** into the table; the id IS the hash of the exact + grader-visible bundle bytes (id slot tokenized), so every rendered thing — + per-run extraction text, header, labels — is bound by construction. + `verdict` re-hashes the bundle file and rejects a table whose id does not + match; extraction prompt/model identity is enforced separately by the + per-run extraction metadata that `compare` requires to be homogeneous; and + any verdict computed without a blinded bundle is labeled NON-GATING. +4. **Hallucination check:** a `caught` entry's evidence quote must actually + name the defect; a finding claiming to have verified behavior the plan/repo + cannot produce is graded as an FP-class note, never a catch. +5. **Adversarial reconciliation:** any cell where the graders disagree goes to + a verifier agent that re-reads that case's blinded extractions (and, only + on dispute, may consult the raw reviews) and rules with quoted evidence. +6. Only after the reconciled table is final are labels unblinded via + `blinding.json` and the gates applied mechanically (`verdict.py`). + +## Blinding caveats (accepted) + +- Extraction is itself an LLM stage and could drop a catch; mitigations: the + verbatim-quote requirement, the dress rehearsal (an extraction error that + drops a fixture catch fails the rehearsal), and raw-on-dispute in + reconciliation.

A subdirectory IS a campaign: its protocol identity is registered write-once, BEFORE any reviewer call (a crash mid-matrix leaves a registered campaign with empty run_keys, never an orphaned cache), and any invocation under a different protocol refuses to touch it — so the store's cached outcomes can never be re-attributed to a later protocol by editing DECISION_RULE.md and re-running the same subdir. Smoke keeps re-registering its fixture subdir freely (never gating, never graded). The external codex wrapper (.claude/scripts/openai_review.py, importlib-executed by dual arms) joins the evaluator identity, and the snapshot now proves imported code == hashed bytes via a read->import->re-read stability bracket: the executing modules are imported inside the bracket and the snapshot aborts if any source changed across it (closing the snapshot-then-import window). Claude redaction is narrowed to MODEL-shaped tokens ("claude" + version or family tail, e.g. claude-fable-5, Claude 3.5, claude_opus; standalone family words unchanged). The previous pattern treated the repository's own .claude/ tree as a model name — `.claude/hooks/check-plan-review.py` became `.[model-redacted]/hooks/...` in blinded bundles, mangling exactly the evidence quotes graders score against ground truth and downgrading genuine catches to misses. Bare "claude" carries no arm signal (every arm runs the claude CLI); regressions pin both directions, including the composed evidence-quote case. Shared-engine change: reviewer-eval inherits the narrowed pattern (its blinding tests stay green). The corpus loader now enforces the complete manifest.schema.json contract: stratum must be a known enum value (an unknown stratum directory previously loaded, verified, and counted toward the pre-registered >=8-case floor), class_keywords/expected_files/allow_severities must be string lists (a string class_keywords silently became a character list in grader-visible evidence), fixture and provenance must be objects with string fields, and known_fp_topics entries must be objects. Regressions: external-wrapper identity membership; mid-import source-drift abort; write-once-per-protocol refusal (resume under the recorded protocol stays allowed); registration-before-observation on a mid-matrix crash; unknown-stratum and string-class_keywords rejection; .claude-path/CLAUDE.md preservation alongside model-id redaction. --- tests/test_evals_engine.py | 37 +++++ tests/test_plan_review_eval.py | 114 ++++++++++++++++ tools/eval_core/compare.py | 11 +- .../plan_adapters/corpus_loader.py | 39 +++++- tools/plan-review-eval/run_eval.py | 128 ++++++++++++++---- 5 files changed, 300 insertions(+), 29 deletions(-) diff --git a/tests/test_evals_engine.py b/tests/test_evals_engine.py index 97033c4ee..6a605fa14 100644 --- a/tests/test_evals_engine.py +++ b/tests/test_evals_engine.py @@ -225,6 +225,43 @@ def test_sanitize_model_refs_scrubs_names_tiers_and_versions(): assert " 5.5 " not in f" {out} " +def test_sanitize_preserves_claude_paths_and_prose(): + """Claude redaction is MODEL-shaped only: repository paths (`.claude/...`, + `CLAUDE.md`) and generic prose ("the Claude workflow") must survive intact + — a broader pattern mangled the very evidence quotes graders score against + ground truth, downgrading genuine catches to misses (plan-review CI + round-8).

The corpus schema's discriminator is enforced end-to-end: fixture.kind must be the schema constant "plan_at_sha" at load (a copied "git_range" case previously verified and counted toward the corpus floor while being silently materialized as a plan_at_sha checkout — reviewing the wrong repository state), base_sha is schema-required, and materialize() refuses unknown kinds as defense in depth. Campaign registration now freezes the SAMPLE PLAN, not just the protocol: the registered manifest carries a campaign fingerprint (arms, k, overrides, and per-case declared base_sha + frozen plan bytes), and an invocation differing in protocol OR fingerprint refuses the subdirectory — an outcome-dependent change to cases, plan content, or repeat schedule after results exist is a new campaign, never a rewrite of this one. README gains "Provenance guarantees and limits": what the machinery guarantees (whole-tree identity incl. the external wrapper, bracket-proven execution, write-once registration-before-observation, stage gates, bound extraction/blinding artifacts, recomputed mapping, byte-hash bundle ids) and the documented out-of-scope floor (sub-bracket TOCTOU detected-not- prevented; hostile local writers per the DEFERRED.md threat model; smoke's never-graded fixture subdir). Regressions: bracketed-wrapper wiring (reviewer._mod IS the snapshot's module), fingerprint freeze across six mutation axes (k, arms, overrides, plan bytes, base sha, case set), registration carries the fingerprint, unknown fixture kind rejected at load AND at materialize(). --- tests/test_plan_review_eval.py | 109 +++++++++++++++++- tools/plan-review-eval/README.md | 36 ++++++ .../plan_adapters/corpus_loader.py | 16 ++- .../plan_adapters/plan_reviewer.py | 8 +- .../plan_adapters/worktree.py | 7 ++ tools/plan-review-eval/run_eval.py | 81 ++++++++++--- 6 files changed, 228 insertions(+), 29 deletions(-) diff --git a/tests/test_plan_review_eval.py b/tests/test_plan_review_eval.py index 1f435e316..bfda6948e 100644 --- a/tests/test_plan_review_eval.py +++ b/tests/test_plan_review_eval.py @@ -65,12 +65,19 @@ def test_fixture_case_loads_and_verifies(): assert loader.verify(case) is None +# Minimal schema-valid fixture object for loader tests (the strict validator +# requires the plan_at_sha discriminator + base_sha on every case). +_FX = {"kind": "plan_at_sha", "base_sha": "HEAD"} + + def test_loader_rejects_stratum_mismatch(tmp_path): from plan_adapters.corpus_loader import PlanCorpusLoader d = tmp_path / "cases" / "s1_synthetic" / "bad-case" d.mkdir(parents=True) -

Editing any scoring field after results exist now refuses the subdirectory — outcome-dependent redefinition of ground truth under a registered campaign is closed. ground_truth[].rationale is schema-required and now enforced: the loader rejects a missing, empty, or whitespace rationale (graders match findings against it), and the schema pins minLength 1 so the documented contract and the executable enforcement agree. Regressions: missing/empty/whitespace rationale rejected; two cases identical in plan bytes and base_sha but differing in a scoring field produce different case_shas and different campaign fingerprints, and the fingerprint echoes the loader's stamped hash. --- tests/test_plan_review_eval.py | 82 ++++++++++++++++++- .../corpus/manifest.schema.json | 2 +- .../plan_adapters/corpus_loader.py | 21 ++++- tools/plan-review-eval/run_eval.py | 11 ++- 4 files changed, 108 insertions(+), 8 deletions(-) diff --git a/tests/test_plan_review_eval.py b/tests/test_plan_review_eval.py index bfda6948e..dd4cee081 100644 --- a/tests/test_plan_review_eval.py +++ b/tests/test_plan_review_eval.py @@ -1630,7 +1630,14 @@ def test_loader_keeps_genuine_false_must_catch_optional(tmp_path): "id": "optional-case", "stratum": "s1_synthetic", "fixture": _FX, -

In CI's alphabetical collection the plan-review-eval suite's insert displaced reviewer-eval's, so the reviewer-eval tests executed against the WRONG harness (27 failures: missing CorpusLoader/_resolve_configs, foreign treatment fields). Local runs always listed test_plan_review_eval.py first, which masked the order dependence; the parallelized matrix legs split the suites across workers and never saw it. Fix mirrors test_plan_review_eval.py's existing loader: reviewer-eval tests load their harness CLI by explicit file path under the unique module name reviewer_eval_run_eval (lru-cached), eliminating the ambiguous bare import entirely. With run_eval de-ambiguated, no shared bare module name remains between the harnesses (adapters vs plan_adapters are distinct; verdict.py exists only in plan-review-eval; eval_core is a single shared copy).

charset=UTF-8 Content-Transfer-Encoding: 8bit The extraction stage no longer categorically excludes questions. The control engine's native format raises implementation-blocking ambiguities under "Questions for the Author", so a blanket question exclusion dropped those findings for arm A while the candidate's flat-finding phrasing survived — a systematic bias toward the candidate arms capable of manufacturing a false GO. The rule now extracts a question as a finding when it identifies a missing decision, contradiction, unresolved dependency, or execution blocker (at least `major`; `blocker` when marked blocking), and excludes only non-defect clarifications that assert no gap. The dress rehearsal gains a format-parity extraction probe (DECISION_RULE.md): a committed control-format sample review (corpus/fixture/fx-mini-plan/control_format_review.md) whose ONLY mention of the seeded nonexistent-symbol defect sits under the questions section must survive extraction as a finding, or the rehearsal fails. A deterministic contract test pins the prompt rules (no categorical exclusion, substantive-question inclusion, qualified-only exclusion) and the sample's sole-mention structure. --- tests/test_plan_review_eval.py | 36 +++++++++++++ tools/plan-review-eval/DECISION_RULE.md | 10 ++++ .../candidates/extraction_prompt.md | 11 +++- .../fx-mini-plan/control_format_review.md | 54 +++++++++++++++++++ 4 files changed, 110 insertions(+), 1 deletion(-) create mode 100644 tools/plan-review-eval/corpus/fixture/fx-mini-plan/control_format_review.md diff --git a/tests/test_plan_review_eval.py b/tests/test_plan_review_eval.py index dd4cee081..654e5cd24 100644 --- a/tests/test_plan_review_eval.py +++ b/tests/test_plan_review_eval.py @@ -1901,6 +1901,42 @@ def test_loader_requires_ground_truth_rationale(tmp_path, rationale): PlanCorpusLoader(str(tmp_path), str(_REPO)).load_cases(None) +def test_extraction_prompt_keeps_substantive_questions(): + """CI round-12: the control engine surfaces implementation-blocking + ambiguities under 'Questions for the Author'; a categorical question + exclusion in the extraction rules would drop those findings for arm A + only — a systematic bias toward the candidate arms (false GO).

From 341e4f4a598fa94489d24fef66fa189d2d61a631 Mon Sep 17 00:00:00 2001 From: igerber Date: Mon, 20 Jul 2026 20:22:26 -0400 Subject: [PATCH 7/7] Guard the real-pin control-prompt test for shallow clones MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The label-gated CI matrix is otherwise green (9768 passed); the one failure was test_control_prompt_participates_in_protocol_identity, whose load_artifacts call materializes the control criteria from the REAL pinned SHA — absent in CI's depth-1 checkout. The step-1 plan's own rule (hermetic tmp-repo tests cover the git-show mechanism; real-pin tests skip on shallow clones) was applied to test_configured_pin_resolves_in_full_clone but missed on this round-4 regression test. The probe is factored into _skip_unless_pin_available(), shared by both real-pin tests; the control-prompt test still asserts the snapshot's control_prompt_sha plumbing unconditionally and skips only the load_artifacts materialization when the pin is unreachable. Verified in a local depth-1 clone (the exact CI condition): both tests skip, the rest of the suite passes; full clone still runs both. --- tests/test_plan_review_eval.py | 23 +++++++++++++++++------ 1 file changed, 17 insertions(+), 6 deletions(-) diff --git a/tests/test_plan_review_eval.py b/tests/test_plan_review_eval.py index 654e5cd24..4d94d56d4 100644 --- a/tests/test_plan_review_eval.py +++ b/tests/test_plan_review_eval.py @@ -202,19 +202,28 @@ def test_git_show_fails_actionably_on_unknown_path(tmp_path): git_show(str(repo), sha, "nope.md") -def test_configured_pin_resolves_in_full_clone(): - """The REAL configs.json pin, guarded for shallow clones (CI is depth-1).""" - from plan_adapters.criteria_source import git_show - +def _skip_unless_pin_available(): + """Real-pin guard (golden-file-skip pattern): CI checkouts are depth-1, so + the pinned control SHA may be absent — hermetic tmp-repo tests cover the + git-show mechanism everywhere; tests touching the REAL pin skip on + shallow clones instead of failing.""" cfg = json.loads((_EVAL_ROOT / "config" / "configs.json").read_text()) - pin = cfg["control_criteria"] probe = subprocess.run( - ["git", "cat-file", "-e", f"{pin['sha']}^{{commit}}"], + ["git", "cat-file", "-e", f"{cfg['control_criteria']['sha']}^{{commit}}"], cwd=_REPO, capture_output=True, ) if probe.returncode != 0: pytest.skip("pinned control SHA not present (shallow clone)") + + +def test_configured_pin_resolves_in_full_clone(): + """The REAL configs.json pin, guarded for shallow clones (CI is depth-1).""" + from plan_adapters.criteria_source import git_show + + _skip_unless_pin_available() + cfg = json.loads((_EVAL_ROOT / "config" / "configs.json").read_text()) + pin = cfg["control_criteria"] text = git_show(str(_REPO), pin["sha"], pin["path"]) assert "Review Plan" in text and len(text) > 10_000 @@ -1427,6 +1436,8 @@ def test_control_prompt_participates_in_protocol_identity(): snap["identity"]["control_prompt_sha"] == _hashlib.sha256(snap["control_prompt"].encode()).hexdigest()[:16] ) + # load_artifacts materializes the control criteria from the REAL pin. + _skip_unless_pin_available() arts = load_artifacts( str(_REPO), str(_EVAL_ROOT),
