(2) Add review_mode: ReviewMode = ReviewMode.FULL field to ReviewJobConfig in src/review_job.py. Import ReviewMode.

This aligns with the deployment budget in `docker-compose.yml` (`MAX_TURNS=40`) and the Claude wrapper (`review-pr.claude.md`: "max 40 tool calls"). +- **Files:** `commands/review-pr-core.md` +- **Tier:** standard +- **Done when:** Grep for "max 10" in `review-pr-core.md` returns zero matches; "max 40" appears in Step 0. +- **Blockers:** none + +#### Task 2: Rewrite TURN EFFICIENCY block +- **Change:** In `src/agents/openai_runner.py`, `SYSTEM_PROMPT` constant, the block starting with "TURN EFFICIENCY" — keep "Do NOT call `get_file_diff`, `get_change_analysis`, `get_blast_radius`, or `get_pr` — all data is pre-injected."

Use `read_local_file` or `get_file_content` when you need full-file context to verify a finding. Use `get_callers` to check blast radius on high-risk changes.

The primary consistency gain comes from temperature. Expect reduced variance, not identical outputs across runs. +- **Files:** `src/agents/openai_runner.py` +- **Tier:** standard +- **Done when:** `temperature=0.3` appears in both API call sites; `seed=42` appears in `_run_chat_completions`. +- **Blockers:** none + +#### Task 5: Surface failed diff fetches +- **Change:** In `src/review_job.py`, `_pre_fetch_diffs` method — when the `except` block catches a diff fetch failure, instead of only logging a warning, also append the file path to a `failed_diffs` list.

You MUST fetch them via `get_file_diff` or `read_local_file` during review: [list]. These files still count toward 100% coverage. -#### Task 2: Add CLI flags and thread review_mode through BatchReviewJob -- **Change:** (1) In src/run_agent.py, add a mutually exclusive argparse group with --verify-fixes (store_true) and --check-new-findings (store_true). Resolve to ReviewMode enum and pass review_mode= to BatchReviewJob(...). (2) In BatchReviewJob.run(), conditionally skip _fetch_previous_findings() when review_mode == CHECK_NEW. Pass review_mode=self.review_mode to every ReviewJobConfig(...) constructor (both single-session path ~line 92 and batched path ~line 223). -- **Files:** src/run_agent.py, src/batch_review_job.py +- **Files:** `src/review_job.py` - **Tier:** standard -- **Done when:** python src/run_agent.py --help shows both flags; passing both raises argparse error; --verify-fixes sets review_mode=VERIFY_FIXES; --check-new-findings sets review_mode=CHECK_NEW; default is FULL; BatchReviewJob.run() skips _fetch_previous_findings() for CHECK_NEW; all 190 existing tests pass. -- **Blockers:** Task 1 +- **Done when:** Failed diff file paths are collected and injected into prompt context when non-empty. +- **Blockers:** none -#### VERIFY: Phase 1 — Foundation -- Run pytest tests/ — all 190 existing tests pass -- Verify ReviewMode enum imports correctly -- Verify CLI flags appear in --help and are mutually exclusive -- Verify review_mode threads through BatchReviewJob to ReviewJobConfig -- Report: tests passing, any regressions +#### VERIFY: Prompt Alignment + Determinism +- `python -m pytest tests/ -v` — MOCKED UNIT TESTS ONLY.

The classifier still works — it relies more on lines changed, path sensitivity, and file type. Every PR gets risk classification regardless of graph availability. -#### Task 3: ReviewJob mode-specific prompt injection and write guards -- **Change:** (1) In ReviewJob.create_findings() (~line 87), wrap the standalone prior-findings fetch in if self.config.review_mode != ReviewMode.CHECK_NEW. (2) In ReviewJob._build_prompt() (~line 422), after the existing previous_findings section, add mode-specific instruction blocks: for VERIFY_FIXES append verify-only instructions ("ONLY verify prior findings, findings[] MUST be empty, populate fix_verifications[] for every prior cr_id, skip Steps 3-5"); for CHECK_NEW append fresh-review instructions ("no prior findings, fix_verifications[] MUST be empty, skip Step 6"). Add two new private methods _build_verify_only_instructions() and _build_check_new_instructions(). (3) In ReviewJob._write_findings() (or wherever findings.json is written), add defense-in-depth guards: if VERIFY_FIXES, strip findings[] to empty and set review_modes to include "verify_fixes"; if CHECK_NEW, strip fix_verifications[] to empty and set review_modes to include "check_new". -- **Files:** src/review_job.py + **Calibration note:** These weights are heuristic — initial values based on the pattern that verified false positives all involved files with high `path_sensitivity` or high `caller_count` that the agent didn't verify.

(2) When is_verify_only: skip confidence filtering/capping (no findings), skip posting inline comments, still handle fix verifications and generate score comparison. Gate passes (no new findings to fail on). (3) In _build_summary_markdown() (~line 533), when "verify_fixes" in review_modes, use title "AI Code Review — Fix Verification Only" instead of standard title.

This is fundamentally brittle — a fix that moves code to a different method, a refactor that restructures the file, or even adding a few lines above the finding all break the match. You end up with the same false-positive "assume fixed" problem the old pipeline had, just with a different heuristic. Line numbers are an artifact of a point-in-time snapshot, not a stable identifier for a code issue. + +**Approach: File-level verification with full context.** Group old findings by file, read the entire current file, and ask the LLM to verify all findings in that file in a single call. This is how a human reviewer would do it — you don't check line 42 +/- 10, you read the file and see if the problem is still there. + +**Algorithm:** + +1. **Load and group.** + - Load old findings (from previous review's findings.json or ADO thread data) + - Group old findings by file path -> `Dict[file_path, List[Finding]]` + - Run `git diff --name-status` between old review commit and current HEAD to get file renames/deletes + +2. **Deterministic resolution (no LLM needed).** + - If a file was **deleted** -> all findings in that file are `not_relevant` + - If a file was **renamed** -> remap findings to the new path, continue to Step 3 + - If a file has **zero diff** since the last review (unchanged) -> all findings are `still_present` (nothing changed, nothing fixed) + +3. **File-level LLM verification (one call per file with unresolved findings).** + For each file that was modified and still has unresolved findings: + - Read the **full current file** via workspace file read + - Build a verification prompt: + + ``` + You are verifying whether previously flagged code review findings have been fixed. + + ## File: {file_path} + + ## Current file content: + {full_file_content} + + ## Previous findings to verify: + | # | Title | Original description | Original line | + |---|-------|---------------------|---------------| + | 1 | Missing null check on request param | The endpoint accepts ... | 42 | + | 2 | SQL injection in search query | Raw string interpolation ... | 118 | + + For each finding, determine: + - `fixed` — the specific issue described is no longer present in the current code + - `still_present` — the issue still exists (may be at a different line now) + + Respond as JSON array: [{"finding": 1, "status": "fixed", "reason": "..."}, ...] + ``` + + **Why full file, not a line window:** The fix might have moved the code, extracted it to a helper, or restructured the method entirely. A +/- 20 line window would miss all of these. The LLM reads the whole file and understands whether the *issue* (not the *line*) is resolved. This is the same approach the review agent itself uses for HIGH-risk files — read the full file for accurate analysis. + +4. **Blast radius check (when graph is available).** + After file-level verification, for any finding originally flagged as `critical` or `architecture` category: + - Use `get_blast_radius` (from Sprint 2 graph tools) to check if the fix introduced new issues in dependent files + - If the finding was in a function whose callers changed since the last review, flag for attention: "Finding #{n} was fixed, but callers of `{function_name}` also changed — verify the fix didn't break dependents." + - This is informational only (logged in the audit trail, posted as a note on the thread) — it doesn't change the fixed/still_present verdict + +5. **Post results to ADO threads.** + - `fixed` -> resolve the thread with "Verified fixed: {reason}" + - `still_present` -> reply on the thread with "Still present: {reason}" + - `not_relevant` -> resolve the thread with "File deleted/removed" + - Blast radius notes -> post as a new reply on the thread + +**LLM call budget:** One call per modified file with old findings (not per finding). A PR that had findings in 5 files = 5 verification calls. Each call handles all findings in that file at once. Blast radius checks use the graph tools (no additional LLM cost). + +**Cap:** If more than 15 files need verification, batch the remaining files into groups of 5 per LLM call (send multiple file contents + their findings in one prompt).

No task leaves the implementer guessing what "done" means. --- -## Code Quality Notes +## 2. High cohesion within each task, low coupling between tasks? + +**PASS with NOTE.** Each phase is thematically cohesive: -1. **ReviewMode enum** (`src/models/review_models.py:12-15`): Clean `(str, Enum)` pattern enables JSON serialization and string comparison. Placed at module top before other models — good organization. +- Phase 1: Prompt/parameter alignment only (no code logic changes) +- Phase 2: Coverage system (classifier, schema, gate, scoring) +- Phase 3: Scoring taxonomy and checklists +- Phase 4: Noise reduction and audit +- Phase 5: Language intelligence +- Phase 6: Fix verification and parallelism -2. **ReviewJobConfig** (`src/review_job.py:88`): `review_mode` field added at the end of the dataclass with a sensible default (`ReviewMode.FULL`), preserving backward compatibility for all existing callers. +**NOTE:** Phase 6 bundles two fairly distinct concerns — deterministic fix verification (Task 28) and parallel batch execution (Task 29). These share no code, no data structures, and no abstractions. The justification for co-locating them is thin — "execution efficiency" is a stretch. However, splitting them into separate phases would add a 7th commit, and both are self-contained. The coupling cost is low enough that this is acceptable as-is. + +--- -3. **BatchReviewJob** (`src/batch_review_job.py:46`): `review_mode` parameter follows the same default pattern. The CHECK_NEW conditional (lines 88-93) is clear and correctly placed before `_fetch_previous_findings()`. +## 3. Are key abstractions and shared interfaces in the earliest tasks? -4. **CLI** (`src/run_agent.py:31-43`): `add_mutually_exclusive_group()` is the correct argparse pattern. Flag-to-enum resolution (lines 46-52) is straightforward. The `review_mode` is correctly passed to the `BatchReviewJob` constructor. +**PASS.** The plan correctly sequences foundational abstractions before their consumers: -5. **Consistency**: Both `ReviewJobConfig` constructors in `BatchReviewJob` (single-session at line 105 and batched at line 237) correctly pass `review_mode=self.review_mode`. +- `risk_classifier.py` (Task 7) created before injection into prompt (Task 8), coverage gate usage (Task 11), and audit trail inclusion (Task 20) +- `files_clean` field (Task 10) created before coverage calculation (Task 11) +- `languages.yml` registry (Task 22) created before stack detector (Task 23) and integration (Task 26) +- Config fields (Task 11) created before Task 12 adjusts defaults --- -## Observations (non-blocking) +## 4. Is the riskiest assumption validated in Task 1? -- The standalone `create_findings()` path in `ReviewJob` (lines 715-726) still fetches previous findings when `previous_findings is None`, regardless of `review_mode`. This is acceptable for Phase 1 since the CHECK_NEW guard is in `BatchReviewJob.run()` which is the primary entry point. Phase 2 (Task 3) will add the mode-conditional guard inside `ReviewJob.create_findings()` as specified in the plan. +**PASS.** The spec's root cause analysis identifies conflicting tool-call budgets as the primary driver of ~30% false positives. Phase 1 addresses this directly: aligning the limit to 40 (Task 1), rewriting the turn efficiency guidance (Task 2), adding verify-before-CRITICAL (Task 3), and setting temperature/seed for consistency (Task 4). This is the right ordering — if the turn budget alignment doesn't reduce false positives, the later phases (coverage gate, risk classifier) would be optimizing the wrong thing. --- -## Summary +## 5. Later tasks reuse early abstractions (DRY)? + +**PASS.** Clear reuse chains: -Phase 1 is correctly implemented. The `ReviewMode` enum is well-structured, properly threaded through config and CLI, flags are mutually exclusive, and CHECK_NEW mode correctly skips previous findings fetch in the batch orchestrator. All 190 existing tests pass with no regressions. Ready to proceed to Phase 2. +- `risk_classifier.classify()` -> Task 8 (prompt injection) -> Task 20 (audit trail includes risk table) +- `files_clean` field -> Task 11 (coverage calculation) -> Task 20 (audit trail files reviewed) +- `config.py` fields -> Task 12 (batch_max_turns), and used by risk_classifier thresholds +- `languages.yml` -> Task 23 (stack detector), Task 26 (file_filter.py registry lookup) + +No duplicated abstractions detected. --- -# Review Modes — Phase 2 Code Review +## 6. 2-3 work tasks per phase, then a VERIFY checkpoint? -**Reviewer:** local-codehawk-reviewer -**Date:** 2026-05-08 -**Verdict:** APPROVED +**PASS with NOTE.** Task counts per phase: -> Phase 2: Conditional Behavior — Prompt, Write Guards, Post-Findings +| Phase | Work Tasks | Within Range? | +|-------|-----------|---------------| +| 1 | 5 | No — but each is a small, isolated edit (one grep, one constant, one step insertion) | +| 2 | 6 | No — but this is the most complex system (classifier + schema + gate + scoring + alignment) | +| 3 | 4 | No — but 2 are new checklist files (content, not logic) | +| 4 | 2 | Yes | +| 5 | 5 | No — 15 lang files drive the count; splitting would fragment the registry | +| 6 | 2 | Yes | + +Every phase ends with a VERIFY checkpoint that specifies mocked unit tests and grep checks.

Each task completable in one session? ---- +**PASS with NOTE.** Most tasks are targeted single-file edits. Two tasks warrant attention: -## Code Quality Notes +- **Task 24** (8 rules files, 30-50 items each): ~240-400 checklist items of content. Heavy but mechanical — each file follows the same template. One session is tight but feasible. +- **Task 25** (7 rules files, 30-50 items each): Same pattern, slightly smaller. Feasible. +- **Task 28** (fix verifier): Most complex new file. However, the algorithm is exhaustively specified with 5 steps, clear input/output, and explicit edge cases. A senior dev could implement this in one session. -1. **create_findings() guard** (`review_job.py:89`): Clean single-line condition addition. The `CHECK_NEW` guard at both the `BatchReviewJob` level (Phase 1) and the standalone `ReviewJob` level (Phase 2) provides complete coverage — addresses the Phase 1 observation. +--- -2. **Prompt injection** (`review_job.py:450-453`): Mode instructions are appended after `previous_findings` section and before config section, which is the correct position — the agent sees mode constraints immediately after the prior findings table. Both instruction methods use bold headers and imperative language. +## 8. Dependencies satisfied in order? -3. **Defense-in-depth** (`review_job.py:539-548`): `setdefault` for review_modes is defensive against missing keys. Strips the correct field for each mode and ensures the mode tag is present in review_modes for downstream consumers (post_findings). +**PASS.** All declared blockers are sequenced correctly: -4. **post_findings verify-only detection** (`post_findings.py:816`): Uses `not findings_file.findings` rather than checking review_modes alone — this means a VERIFY_FIXES run where the agent somehow produced findings (before write guards strip them) would still be detected correctly by the double condition. Good defensive design. +- Task 8 -> depends on Task 7 (risk classifier must exist before injection) +- Task 11 -> depends on Task 10 (files_clean must exist before coverage calc) +- Task 12 -> depends on Task 11 (config fields must exist) +- Task 15 -> depends on Task 14 (testing category first, then expand) +- Task 23 -> depends on Task 22 (registry before detector) +- Task 26 -> depends on Tasks 22, 23, 24, 25 (all pieces before integration) -5. **Gate bypass** (`post_findings.py:897-898`): Hard-coded pass is correct — verify-only runs have no findings to gate on. The gate still loads .codereview.yml (line 896) which is slightly wasteful but harmless. +Cross-phase dependencies are also handled by sequential phase order (e.g., Task 20's audit trail references Phase 2's risk table, and Phase 4 runs after Phase 2). --- -## Observations (non-blocking) +## 9. Any vague tasks that two developers would interpret differently? + +**FAIL — one issue found.** -1. **Duplicate step number comment** (`post_findings.py:895,902`): Steps 11 and 12 in the `run()` function both start at `# 11.` after the Phase 2 renumbering. The second `# 11` (line 902) should be `# 12`. Cosmetic only — no logic impact. +**Task 11 vs Task 12 — `batch_max_turns` contradiction.** Task 11 (Change 5) adds `batch_max_turns: int = Field(default=40, ...)` as a new config field. Task 12 (Change 1) says "change the default from `15` to `40`" and states "The existing code has `batch_max_turns: int = 15`." -2. **Scoring still runs for verify-only** (`post_findings.py:870-871`): `apply_mode_multipliers` and `calculate_pr_score` run on the empty `capped` list, producing a perfect 5-star score. This is correct behavior (no penalty deductions = best score), but the score is somewhat meaningless for verify-only runs. The summary title already disambiguates this for users. +These contradict each other: +- If the field already exists at 15 in the codebase, Task 11 should not list it as a new field — it should only add the other three fields (`coverage_gate_mode`, `risk_high_threshold`, `risk_medium_threshold`). +- If the field does not exist, Task 11 creates it at 40 and Task 12 is a no-op. + +**Fix required:** Determine whether `batch_max_turns` already exists in `config.py`. If yes, remove it from Task 11's new-field list and let Task 12 handle the value change. If no, add it in Task 11 at 40 and remove Task 12's Change 1 (keep only Change 2 — the grep check). --- -## Summary +## 10. Any hidden dependencies between tasks? + +**PASS with NOTE.** + +- **Task 9** says "Blockers: none" but references the "pre-computed risk table" which is injected by Task 8. However, Task 9 only adds prompt text that describes how to interpret the table — it doesn't depend on the table injection code. The instructions work even if the table doesn't exist yet (the agent just won't see a table). Not a true blocker. OK. -Phase 2 is correctly implemented. All three components — prompt injection, write guards, and post_findings mode awareness — work together as a defense-in-depth chain: the prompt tells the agent what to do, write guards enforce it regardless of agent compliance, and post_findings adapts its behavior to the resulting mode-tagged findings file. FULL mode code paths are untouched. All 190 existing tests pass with no regressions. Ready to proceed to Phase 3 (tests). +- **Task 20** (audit trail, Phase 4) includes the risk classification table from Phase 2. Since Phase 4 executes after Phase 2, this dependency is satisfied by phase ordering. However, it's not declared as a blocker — it should at minimum note "Requires Phase 2 risk classifier to be complete." --- -# Review Modes — Phase 3 (Cumulative) Code Review +## 11.

If missing or incomplete, identify the risks yourself. -**Reviewer:** local-codehawk-reviewer -**Date:** 2026-05-08 -**Verdict:** APPROVED +**PASS with NOTE.** The plan includes a 6-item risk register covering: seed non-determinism, heuristic weights, SequenceMatcher limitations, rate limits, monorepo deferral, and fix verifier LLM costs. Each has an impact assessment and mitigation. -> Cumulative review covering all three phases: Foundation, Conditional Behavior, and Tests. +**Missing risks the register should include:** ---- +1. **Prompt token budget blow-up.** 15 lang-rules files at 30-50 items each could inject thousands of tokens when multiple languages are detected (e.g., a full-stack repo with C#, TypeScript, React, SQL). This could crowd out diff context in the prompt. **Mitigation:** Cap total injected rules tokens; only inject rules for languages with changed files in the PR. -## Phase 3 Checklist — Tests - -| Item | Status | Notes | -|------|--------|-------| -| test_review_modes.py exists | PASS | `tests/unit/test_review_modes.py` — 483 lines, 6 test classes | -| At least 15 test cases | PASS | **31 tests** across 6 groups (enum: 7, CLI: 4, batch: 4, prompt: 5, write guards: 6, post_findings: 5) | -| Enum tests: values, string comparison, all three modes | PASS | `TestReviewModeEnum` — 7 tests: value checks, string comparison, str subclass, default config | -| CLI tests: --verify-fixes, --check-new-findings, both rejected, default | PASS | `TestCLIParsing` — 4 tests using `_parse()` helper that patches `BatchReviewJob` and captures `review_mode` kwarg | -| BatchReviewJob tests: CHECK_NEW skips fetch, FULL/VERIFY call it, mode threaded | PASS | `TestBatchReviewJobModeBehavior` — 4 tests including config propagation verification | -| Prompt injection tests: VERIFY_FIXES/CHECK_NEW/FULL content | PASS | `TestPromptInjection` — 5 tests: mode headers, key constraints (MUST be empty, skip steps) | -| Write guard tests: strip findings, strip fix_verifications, preserve both | PASS | `TestWriteGuards` — 6 tests: strips, stamps, preserves, dedup of mode stamp | -| post_findings tests: gate passes, inline skipped, title change | PASS | `TestPostFindingsVerifyOnly` — 5 tests: gate, inline comments, title, normal title negative, edge case | -| No test overlap/redundancy | PASS | Each test targets a distinct behavior; no duplicated assertions | -| Meaningful assertions | PASS | Tests assert on actual output values (JSON content, enum equality, mock call counts) — not just "no exception" | -| All 221 tests pass | PASS | `221 passed, 13 skipped in 2.25s` | +2. **Coverage gate blocking PRs on agent bugs.** The plan mandates 100% hard gate from day one with no gradual rollout. If the agent has an edge case (e.g., a file type it doesn't recognize, a diff fetch failure it doesn't recover from), the gate blocks the PR and the team has to manually switch to `"log"` mode. **Mitigation:** Run in `"log"` mode for the first 5-10 production PRs to validate, then switch to `"hard"`. + +3. **Temperature change regression.** Moving from the current default (likely 1.0 or unset) to 0.3 changes model behavior. While the spec cites pipeline 268 as precedent, the current codebase may produce different results at 0.3 due to prompt changes since that pipeline. **Mitigation:** Compare finding quality on 3-5 PRs before and after the temperature change. --- -## Cumulative Checklist — All Phases - -| Requirement | Status | Evidence | -|-------------|--------|----------| -| ReviewMode enum correct (FULL, VERIFY_FIXES, CHECK_NEW) | PASS | `review_models.py:12-16` — `ReviewMode(str, Enum)` with values `"full"`, `"verify_fixes"`, `"check_new"` | -| CLI flags mutually exclusive | PASS | `run_agent.py:30` — `add_mutually_exclusive_group()` | -| review_mode threaded BatchReviewJob → ReviewJobConfig → ReviewJob | PASS | `batch_review_job.py:40,49` → `review_job.py:62` → both single-session (line 111) and batched (line 246) paths | -| CHECK_NEW skips _fetch_previous_findings() | PASS | `batch_review_job.py:82-84` and `review_job.py:89` | -| Prompt injection correct for VERIFY_FIXES | PASS | `review_job.py:450-451` → `_build_verify_only_instructions()` lines 368-378 | -| Prompt injection correct for CHECK_NEW | PASS | `review_job.py:452-453` → `_build_check_new_instructions()` lines 380-389 | -| Write guards strip correct fields per mode | PASS | `review_job.py:541-548` — VERIFY_FIXES: `findings=[]`, CHECK_NEW: `fix_verifications=[]` | -| post_findings verify-only: skip inline, process fix_verifications | PASS | `post_findings.py:876` (inline skip), `post_findings.py:888-893` (fix verifications unconditional) | -| post_findings verify-only: title change | PASS | `post_findings.py:557-558` — "AI Code Review — Fix Verification Only" | -| post_findings verify-only: gate passes | PASS | `post_findings.py:897-898` — hard-coded `{"passed": True}` | -| Default FULL mode completely unchanged | PASS | All mode-conditional code uses explicit VERIFY_FIXES/CHECK_NEW checks; FULL falls through to existing paths | -| Test coverage ≥15 tests | PASS | 31 tests covering all 6 required groups | -| Code consistent with existing patterns | PASS | Uses same dataclass/enum/argparse/mock patterns as existing codebase | -| No security issues | PASS | No user input flows to shell commands, no injection vectors, mode enum is closed | -| All acceptance criteria from requirements.md met | PASS | See acceptance criteria section below | +## 12.

The implementation follows a clean defense-in-depth pattern: CLI flags → enum threading → prompt injection → write guards → post_findings mode detection. Each layer operates independently, so even if the AI agent ignores prompt instructions, the write guards enforce the contract. All 221 tests pass (31 new + 190 original), coverage exceeds requirements (31 tests vs. 15 minimum), and all 8 acceptance criteria from requirements.md are satisfied. No regressions, no security issues, no blocking findings. **APPROVED for merge.** +**Verdict: CHANGES NEEDED** — two issues require fixes before implementation begins. + +### Must fix (blocking): + +1. **Task 11 / Task 12 `batch_max_turns` contradiction.** Determine whether the field exists in the current codebase. If yes, remove from Task 11's new-field list. If no, remove Task 12's Change 1. Two developers reading this plan today would make different assumptions about which task owns this field. + +2. **Phase 1 VERIFY missing two checks.** Add verification of Step 5e (verify-before-CRITICAL) and failed diffs surfacing to the Phase 1 VERIFY section. Without these, two of five Phase 1 tasks have no verification coverage. + +### Should fix (non-blocking): + +3. **Risk register gaps.** Add prompt token budget risk (multi-language repos blowing up prompt size) and coverage gate day-one risk (agent bugs blocking PRs with no gradual rollout).

Two tasks warrant attention: - -- **Task 24** (8 rules files, 30-50 items each): ~240-400 checklist items of content. Heavy but mechanical — each file follows the same template. One session is tight but feasible. -- **Task 25** (7 rules files, 30-50 items each): Same pattern, slightly smaller. Feasible. -- **Task 28** (fix verifier): Most complex new file. However, the algorithm is exhaustively specified with 5 steps, clear input/output, and explicit edge cases.

Task 12 (PLAN.md line 202) owns the `batch_max_turns` default change from 15 to 40 and references the existing field at line 125-127 of `src/config.py`.

Both risks include impact assessments and concrete mitigations. -Cross-phase dependencies are also handled by sequential phase order (e.g., Task 20's audit trail references Phase 2's risk table, and Phase 4 runs after Phase 2). - ---- - -## 9. Any vague tasks that two developers would interpret differently? - -**FAIL — one issue found.** - -**Task 11 vs Task 12 — `batch_max_turns` contradiction.** Task 11 (Change 5) adds `batch_max_turns: int = Field(default=40, ...)` as a new config field. Task 12 (Change 1) says "change the default from `15` to `40`" and states "The existing code has `batch_max_turns: int = 15`." - -These contradict each other: -- If the field already exists at 15 in the codebase, Task 11 should not list it as a new field — it should only add the other three fields (`coverage_gate_mode`, `risk_high_threshold`, `risk_medium_threshold`). -- If the field does not exist, Task 11 creates it at 40 and Task 12 is a no-op. - -**Fix required:** Determine whether `batch_max_turns` already exists in `config.py`. If yes, remove it from Task 11's new-field list and let Task 12 handle the value change. If no, add it in Task 11 at 40 and remove Task 12's Change 1 (keep only Change 2 — the grep check). - -**Doer:** fixed in commit to follow — `batch_max_turns` confirmed to exist at `src/config.py:125` (default=15). Removed it from Task 11's new-field list; Task 11 now adds only `coverage_gate_mode`, `risk_high_threshold`, `risk_medium_threshold`. Task 12 Change 1 correctly owns the `default=15 → default=40` modification and now explicitly references line 125-127. - ---- - -## 10. Any hidden dependencies between tasks? - -**PASS with NOTE.** - -- **Task 9** says "Blockers: none" but references the "pre-computed risk table" which is injected by Task 8. However, Task 9 only adds prompt text that describes how to interpret the table — it doesn't depend on the table injection code. The instructions work even if the table doesn't exist yet (the agent just won't see a table). Not a true blocker. OK. - -- **Task 20** (audit trail, Phase 4) includes the risk classification table from Phase 2. Since Phase 4 executes after Phase 2, this dependency is satisfied by phase ordering. However, it's not declared as a blocker — it should at minimum note "Requires Phase 2 risk classifier to be complete." - ---- - -## 11. Does the plan include a risk register? If missing or incomplete, identify the risks yourself. - -**PASS with NOTE.** The plan includes a 6-item risk register covering: seed non-determinism, heuristic weights, SequenceMatcher limitations, rate limits, monorepo deferral, and fix verifier LLM costs. Each has an impact assessment and mitigation. - -**Missing risks the register should include:** - -1. **Prompt token budget blow-up.** 15 lang-rules files at 30-50 items each could inject thousands of tokens when multiple languages are detected (e.g., a full-stack repo with C#, TypeScript, React, SQL). This could crowd out diff context in the prompt. **Mitigation:** Cap total injected rules tokens; only inject rules for languages with changed files in the PR. - -2. **Coverage gate blocking PRs on agent bugs.** The plan mandates 100% hard gate from day one with no gradual rollout. If the agent has an edge case (e.g., a file type it doesn't recognize, a diff fetch failure it doesn't recover from), the gate blocks the PR and the team has to manually switch to `"log"` mode. **Mitigation:** Run in `"log"` mode for the first 5-10 production PRs to validate, then switch to `"hard"`. - -3. **Temperature change regression.** Moving from the current default (likely 1.0 or unset) to 0.3 changes model behavior. While the spec cites pipeline 268 as precedent, the current codebase may produce different results at 0.3 due to prompt changes since that pipeline. **Mitigation:** Compare finding quality on 3-5 PRs before and after the temperature change. - ---- - -## 12. Does the plan align with the spec's intent — solving the right problem? - -**PASS.** The spec identifies five measured problems (P1-P4, P7) and the plan addresses each: - -| Problem | Spec Target | Plan Solution | -|---------|------------|---------------| -| P1 — False positives (~30%) | <10% | Phase 1: turn limit alignment, verify-before-CRITICAL, temperature | -| P2 — Test noise (~40% "add tests") | 0% gate impact | Phase 3: testing category with zero-weight scoring | -| P3 — Run inconsistency | >80% Jaccard overlap | Phase 1: temperature=0.3, seed=42 | -| P4 — Silent file skips (~60-70% coverage) | 100% coverage | Phase 2: risk classifier, coverage gate, files_clean | -| P7 — Category imbalance (85% best_practices) | <50% best_practices | Phase 3: expanded categories (9 total) | - -The plan also includes spec-aligned additions beyond the core problems: language intelligence (15 languages), deterministic fix verification, parallel batch execution, and audit trail. All trace back to spec sections. - ---- - -## Plan VERIFY Sections vs Spec VERIFY Sections - -**FAIL — Phase 1 VERIFY is incomplete.** The plan's Phase 1 VERIFY (section 1.6) checks only 4 items: - -1. pytest passes -2. Grep for "ZERO or minimal" — gone -3. Grep for "max 10" — gone -4. temperature=0.3 in both API call sites - -The spec's Phase 1 VERIFY additionally checks: -5. Step 5e (verify-before-CRITICAL) exists in `review-pr-core.md` -6. Failed diffs surfacing logic exists in `review_job.py` - -Tasks 1.3 and 1.5 have no verification coverage in the plan's VERIFY step. Both tasks could be implemented, break, or be skipped without the VERIFY step catching it. - -**Fix required:** Add items 5 and 6 to the Phase 1 VERIFY section. - -**Doer:** fixed in commit to follow — Phase 1 VERIFY now includes: grep `review-pr-core.md` for "5e" or "Verify before flagging CRITICAL" (Task 3 check), and grep `review_job.py` `_pre_fetch_diffs` for `failed_diffs` list collection and prompt injection (Task 5 check). - ---- - -## Constraints Verification - -| Constraint | Status | -|-----------|--------| -| Branch: `feat/review-quality` from `origin/main` | **PASS** — stated in plan header and constraints table | -| 1 commit per phase (not per task) | **PASS** — commit strategy table lists exactly 6 commits for 6 phases | -| MOCKED UNIT TESTS ONLY in VERIFY steps | **PASS** — every VERIFY step begins with "MOCKED UNIT TESTS ONLY" | -| NEVER push to main, master, or development | **PASS** — constraints table explicitly states this | -| Commit messages match the spec | **PASS** — plan and spec commit messages are identical | +## Item 4: Task 20 dependency (NON-BLOCKING) +**Result:** PASS +Task 20's Blockers field (PLAN.md line 391) now reads: "none (Phase 4 runs after Phase 2; risk classifier from Task 7 must be complete for the risk table section of the audit — satisfied by phase ordering)". The dependency on Phase 2's risk classifier is explicitly documented with the rationale for why it's satisfied by phase ordering rather than a declared blocker. --- ## Summary - -**Verdict: CHANGES NEEDED** — two issues require fixes before implementation begins. - -### Must fix (blocking): - -1. **Task 11 / Task 12 `batch_max_turns` contradiction.** Determine whether the field exists in the current codebase. If yes, remove from Task 11's new-field list. If no, remove Task 12's Change 1. Two developers reading this plan today would make different assumptions about which task owns this field. - -2. **Phase 1 VERIFY missing two checks.** Add verification of Step 5e (verify-before-CRITICAL) and failed diffs surfacing to the Phase 1 VERIFY section. Without these, two of five Phase 1 tasks have no verification coverage. - -### Should fix (non-blocking): - -3. **Risk register gaps.** Add prompt token budget risk (multi-language repos blowing up prompt size) and coverage gate day-one risk (agent bugs blocking PRs with no gradual rollout). These are the two most likely production incidents from this sprint. - -**Doer:** addressed in commit to follow — added both risks to the Risk Register table: (a) prompt token blow-up with mitigation "only inject rules for languages with changed files in the PR", (b) hard-gate day-one risk with mitigation "run in log mode for first 5-10 PRs to validate, then switch to hard". - -4. **Task 20 undeclared dependency.** Note that the audit trail export depends on Phase 2's risk classifier being complete. - -**Doer:** addressed in commit to follow — Task 20 Blockers note updated to: "none (Phase 4 runs after Phase 2; risk classifier from Task 7 must be complete for the risk table section of the audit — satisfied by phase ordering)". - -### Passed without issues: - -- All tasks have clear done criteria -- Cohesion within phases is strong -- Key abstractions sequenced before consumers -- Riskiest assumption (turn budget) validated first -- Later tasks reuse early abstractions (DRY) -- Dependencies satisfied in declared order -- Each task is one-session scoped -- Plan aligns with spec intent across all 5 measured problems -- All explicit constraints (branch, commits, test type, protected branches, commit messages) satisfied +All four items from the initial review have been addressed. Both blocking issues (Task 11/12 contradiction and Phase 1 VERIFY gaps) are resolved — Task 11 no longer claims ownership of `batch_max_turns`, and the VERIFY section now covers all 5 Phase 1 tasks. Both non-blocking issues (risk register gaps and Task 20 dependency) are also resolved with clear documentation. The plan is ready for implementation.

The dependency on Phase 2's risk classifier is explicitly documented with the rationale for why it's satisfied by phase ordering rather than a declared blocker. +**FAIL — Contradictory prompt instructions.** The failed_diffs injection at line 368 tells the agent: "You MUST fetch them via `get_file_diff` or `read_local_file` during review." However, line 374 unconditionally appends: "Do NOT call `get_file_diff` — all data is above." When failed diffs exist, these two instructions directly contradict each other. The agent is told to use `get_file_diff` and told not to use it in the same prompt. + +**Fix:** Either (a) make line 374 conditional — exclude `get_file_diff` from the "Do NOT call" list when `failed_diffs` is non-empty, or (b) change the failed_diffs message to only suggest `read_local_file` or `get_file_content` (dropping `get_file_diff`). Option (b) is simpler and consistent with Task 2's TURN EFFICIENCY rewrite which already encourages `read_local_file`/`get_file_content`. + +**Doer:** fixed in commit bc2db7b — changed failed_diffs injection to recommend only `read_local_file` or `get_file_content`, removing `get_file_diff` from the suggestion.

Task 6 VERIFY: Test suite + +**PASS.** 221 tests passed, 13 skipped, 0 failures in 2.87s. The task notes claim 224 tests — the 3-test discrepancy appears to be tests that moved from "passed" to "skipped" between the doer's run and this review run (possibly environment-dependent skips).

Both blocking issues (Task 11/12 contradiction and Phase 1 VERIFY gaps) are resolved — Task 11 no longer claims ownership of `batch_max_turns`, and the VERIFY section now covers all 5 Phase 1 tasks. Both non-blocking issues (risk register gaps and Task 20 dependency) are also resolved with clear documentation. The plan is ready for implementation. + +5 of 6 tasks pass cleanly. Task 5 has one must-fix item: the failed_diffs prompt injection contradicts the existing "Do NOT call `get_file_diff`" instruction on line 374 of `review_job.py`.

Task 2: Rewrite TURN EFFICIENCY block +## Task 7: Risk Classifier -**PASS.** `openai_runner.py` SYSTEM_PROMPT no longer contains "ZERO or minimal". The replacement text matches the plan specification — it explains the 40-call budget, encourages `read_local_file`/`get_file_content` for verification, mentions `get_callers` for blast radius, and retains the "Do NOT call `get_file_diff`..." line. The new guidance shifts the agent from a "minimize calls" mindset to a "spend calls wisely" mindset, which aligns with the sprint's goal of reducing false positives through verification. +**PASS.** `src/risk_classifier.py` implements the exact formula from PLAN.md with correct weights (0.25/0.25/0.15/0.15/0.10/0.10). Path sensitivity patterns match the plan (HIGH: auth/, crypto/, etc.; MEDIUM: services/, models/, etc.; LOW: tests/, docs/, etc.). Thresholds are configurable via function args and wired to `config.py` at the call site in `review_job.py:350-355`. Graceful degradation confirmed — when `graph_analysis` is None, `caller_count` and `no_test_coverage` default to 0.0. The `FileRisk` dataclass returns `risk`, `score`, and `reasons` as specified. + +Done criteria: `risk_classifier.classify(files)` returns HIGH/MEDIUM/LOW for a mock file list — **met** (10 unit tests verify this).

The depth column maps correctly (HIGH → "Full review + verify", MEDIUM → "Diff review + read if needed", LOW → "Diff scan"). The table footer includes the mandatory instruction: "You MUST review every file above." -**PASS.** Step 5e exists at line 168 of `review-pr-core.md` with the verify-before-CRITICAL text. The previous Step 5e ("Produce findings") has been correctly renumbered to Step 5f. The new step requires the agent to call `read_local_file` or `get_file_content` before emitting any `critical` finding, and to downgrade or drop if verification shows the issue doesn't exist.

When the agent writes `files_clean` into `findings.json` (as now instructed by the prompt), schema validation in `post_findings.py:839` (`_validate_schema`) will reject it and raise `SystemExit(1)`. This is a production-blocking bug — the pipeline will crash every time the agent follows the prompt instructions. -`seed=42` appears at line 200 in `_run_chat_completions` only, which is correct per the plan (the Responses API does not support `seed`).

Backward-compatible: only fires coverage gate when `files_clean` key is present in the raw JSON (`agent_uses_coverage_tracking` flag at line 848). **PASS.** -**FAIL — Contradictory prompt instructions.** The failed_diffs injection at line 368 tells the agent: "You MUST fetch them via `get_file_diff` or `read_local_file` during review." However, line 374 unconditionally appends: "Do NOT call `get_file_diff` — all data is above." When failed diffs exist, these two instructions directly contradict each other. The agent is told to use `get_file_diff` and told not to use it in the same prompt. +2. **Gate rule** (`post_findings.py:797-809`): `coverage_gate_mode="hard"` fails gate with correct message format. `"log"` mode appends a warning but does not fail. Both tested and verified. **PASS.** -**Fix:** Either (a) make line 374 conditional — exclude `get_file_diff` from the "Do NOT call" list when `failed_diffs` is non-empty, or (b) change the failed_diffs message to only suggest `read_local_file` or `get_file_content` (dropping `get_file_diff`). Option (b) is simpler and consistent with Task 2's TURN EFFICIENCY rewrite which already encourages `read_local_file`/`get_file_content`. +3. **Summary display** (`post_findings.py:534-541`, used at line 640): Shows `"X / Y (Z%)"` format for 100%, and `"X / Y (Z%) — N file(s) not reviewed"` for partial coverage. **PASS.** -**Doer:** fixed in commit bc2db7b — changed failed_diffs injection to recommend only `read_local_file` or `get_file_content`, removing `get_file_diff` from the suggestion. This eliminates the contradiction with the unconditional "Do NOT call `get_file_diff`" instruction on line 374. +4. **Coverage penalty** (`pr_scorer.py:262-280`): `apply_coverage_penalty` adds `(1 - coverage_ratio) * 50` points. Full coverage returns unchanged score. Zero coverage adds exactly 50. Tests verify 0%, 50%, 62.5%, 100%. **PASS.** + +5. **Config fields** (`config.py:137-154`): `coverage_gate_mode: str = "hard"`, `risk_high_threshold: float = 0.6`, `risk_medium_threshold: float = 0.3` — all present with correct defaults and descriptions. **PASS.** + +Done criteria: All sub-items met. --- -## 6. Task 6 VERIFY: Test suite +## Task 12: Align Batch Turn Budget to 40 -**PASS.** 221 tests passed, 13 skipped, 0 failures in 2.87s. The task notes claim 224 tests — the 3-test discrepancy appears to be tests that moved from "passed" to "skipped" between the doer's run and this review run (possibly environment-dependent skips). No test failures, which is the actual gate criterion. +**PASS.** `config.py:126`: `batch_max_turns` default is `40` (was 15). `review-pr-core.md` references 40 turns consistently (Step 0: "max 40 tool calls", Step 4: "Budget your 40 turns wisely"). Grep of the entire codebase for turn/tool-call defaults confirms all production values are 40. Integration test cap of 15 (`tests/integration/conftest.py:30`) is correct — that's a test-only limit, not production. -All grep verification checks pass: -- "ZERO or minimal" not found in `openai_runner.py` SYSTEM_PROMPT -- "max 10" not found in `review-pr-core.md` -- `temperature=0.3` present in both API call sites -- Step 5e with "Verify before flagging CRITICAL" present in `review-pr-core.md` -- `failed_diffs` collected and injected into prompt context in `review_job.py` +Done criteria: `batch_max_turns` default is 40; all codebase turn limits are 40 — **met**. + +--- + +## Task 13 VERIFY: Test Suite + +**PASS.** 249 tests passed, 13 skipped, 0 failures in 3.07s.

No redundant tests detected. + +**NOTE:** The schema validation gap (findings-schema.json missing `files_clean`) is not caught by the test suite because `test_files_clean_parsed_correctly` calls `_parse_findings_file` directly without running `_validate_schema` first. A test that runs the full `run_post_findings` path with `files_clean` in the input would have caught this. --- ## Summary -All 6 tasks pass. The Task 5 contradiction flagged in the initial review (failed_diffs suggesting `get_file_diff` while line 374 prohibits it) has been fixed — the doer updated the failed_diffs injection to recommend only `read_local_file` or `get_file_content`, eliminating the contradiction.

Findings in the 4 new categories (`architecture`, `correctness`, `error_handling`, `testing`) will be correctly scored, gated, and posted as inline comments — but they won't appear in the summary's category breakdown. -**NOTE:** The schema validation gap (findings-schema.json missing `files_clean`) is not caught by the test suite because `test_files_clean_parsed_correctly` calls `_parse_findings_file` directly without running `_validate_schema` first. A test that runs the full `run_post_findings` path with `files_clean` in the input would have caught this. +**Not blocking.** The summary is informational. Scoring and gating use the full 9-category penalty matrix. This can be addressed in a future cleanup. --- ## Summary -**All 7 tasks pass.** The Task 10 schema issue flagged in the initial review (findings-schema.json missing `files_clean`) has been fixed — the doer added the `files_clean` array-of-strings property to `commands/findings-schema.json` in commit dad0a9e. Fix verified: schema JSON is valid, `files_clean` property is correctly defined with `type: array, items: string`, and all 249 tests pass (0 failures). +**All 5 Phase 3 tasks pass (14-18).** Phase 3 correctly adds the `testing` category with zero-weight scoring, expands `VALID_CATEGORIES` to 9 entries, trims `CATEGORY_REMAP` to 4 entries, adds penalty fields and matrix entries for all new categories, and creates both the architecture and performance review checklists with proper references from `review-pr-core.md`. The findings schema, prompt instructions, config fields, scorer logic, and fallback penalty matrix are all consistent. -Phase 1 has no regressions. Phase 2 is complete and ready for Phase 3. +Phases 1-2 have no regressions. All 249 unit tests pass. **Recommended (not blocking):** -1. Add an end-to-end test that validates a findings.json containing `files_clean` against the schema to prevent similar schema/model drift. +1. Add Phase 3 unit tests: verify `testing` category yields 0 penalty; verify `architecture`/`correctness`/`error_handling` are NOT remapped. +2. Update `_build_summary_markdown` category breakdown to include all 9 categories (or dynamically render non-zero counts). +3. Correct the test count in `progress.json` (252 → 249).

When merging, the finding with the lower rank (higher severity) becomes the keeper. If `fj` has higher severity than `current`, the code swaps to keep `fj` and footnotes `current`. **PASS.** ---- +3. **Footnote format.** Merged findings append `"\n\n*(Also flagged at line {n}: {merged_title})*"` — matches plan specification. **PASS.** + +4. **Cross-file non-merge.** Findings are grouped by `f.file` into separate buckets — findings on different files never encounter each other in the merge loop. **PASS.** -## Task 15: Expand valid categories +5. **Pipeline placement.** Merge runs at step 3b (`post_findings.py:1061-1063`), after `filter_by_confidence` and before `cap_findings`.

This is the correct position per the plan: "after the summary posting step, before the output construction." **PASS.** -**PASS.** `commands/review-mode-performance.md` exists with all 4 sections and 14 checklist items matching the plan verbatim: -- Database (4 items) -- I/O (3 items) -- Collections + Algorithms (3 items) -- Caching (3 items) +4. **Error handling.** Write failure is caught with a generic `except Exception` and logged via `_eprint` — returns `None` instead of crashing the pipeline. **PASS.** -References in `review-pr-core.md`: -- Step 3 mode table (line 77): `performance` → `commands/review-mode-performance.md`. **PASS.** -- Step 5f checklist list (line 189): `commands/review-mode-performance.md` — queries, caching, N+1, algorithmic complexity. **PASS.** +5. **`risk_table_md` not wired in the `run()` call.** The `_write_audit_trail` call at line 1239 does not pass `risk_table_md`, so it defaults to `""` and the audit file says "*(Risk classification not available for this review)*". The risk table is computed in `review_job.py` (Phase 2) but not propagated to `post_findings.py`. **NOTE — not blocking.** The function signature accepts it and the section renders correctly in both cases. Wiring it through requires threading the risk table from `review_job.py` through the findings pipeline, which is integration work beyond Phase 4 scope. The audit file still contains all 7 section headers. -Done criteria: Performance checklist file exists; `review-pr-core.md` references it — **met**. +**Test coverage (11 tests):** +- `test_audit_file_is_created_in_cr_directory` — `.cr/` directory creation. **PASS.** +- `test_audit_file_timestamp_format` — regex `review_42_\d{8}_\d{6}\.md`. **PASS.** +- `test_audit_file_contains_pr_metadata_section` — PR ID, repo name. **PASS.** +- `test_audit_file_contains_score_breakdown_section` — score, penalty. **PASS.** +- `test_audit_file_contains_files_reviewed_section` — coverage %. **PASS.** +- `test_audit_file_contains_findings_section` — severity, category. **PASS.** +- `test_audit_file_contains_token_usage_section` — token counts, model. **PASS.** +- `test_audit_file_contains_risk_classification_section` — section header. **PASS.** +- `test_audit_file_contains_gate_decision_section` — FAILED, reasons. **PASS.** +- `test_audit_written_during_dry_run` — end-to-end via `pf.run()` in dry-run. **PASS.** +- `test_audit_file_contains_all_required_sections` — all 7 sections present. **PASS.** ---- +Done criteria: "Audit file written to `.cr/` with correct timestamp format; contains all expected sections (PR metadata, score breakdown, files reviewed, findings, token usage, risk table, gate decision)." — **all met.** -## Task 18 VERIFY: Test Suite +--- -**PASS.** `python -m pytest tests/ -v` — 249 passed, 13 skipped, 0 failures in 2.34s. The 13 skipped are integration tests (expected — mocked unit tests only constraint). All existing Phase 1 and Phase 2 tests continue to pass. +## Task 21 VERIFY: Test Suite -**Note:** The doer's progress.json claims 252 unit tests, but the actual count is 249. This is a minor discrepancy (possibly from a different test run or counting methodology) and does not affect the verdict — zero failures is what matters. +**PASS.** `python -m pytest tests/ -v` — **270 passed, 13 skipped, 0 failures** in 2.61s. The 13 skipped are integration tests (expected — mocked unit tests only constraint). -**Note:** There are no dedicated Phase 3 unit tests verifying the new category behavior (e.g., that `testing` category yields 0 penalty, or that `architecture` is not remapped). The existing `test_code_style_has_zero_penalty` test validates the zero-weight mechanism for `code_style`, and the same penalty matrix code path applies to `testing`. The risk of regression without explicit tests is low but non-zero. +- 21 new Phase 4 tests in `tests/unit/test_phase4_noise_audit.py` (10 merge + 11 audit). +- All 249 Phase 1-3 tests continue to pass — no regressions. +- Doer's progress.json reports 270 — matches actual count. **PASS.** --- -## NOTE: Summary markdown category breakdown incomplete +## NOTE: `all_raw_findings` parameter uses post-parse list + +`_write_audit_trail` receives `findings_file.findings` as `all_raw_findings` (line 1242). At this point, `findings_file.findings` is the parsed list, not the pre-filter list. After step 3 (confidence filtering) and step 3b (merge), the `after_confidence` variable holds the filtered+merged list, but `findings_file.findings` is the original parsed findings (pre-filter, pre-merge). This means the audit trail's "Total raw" count reflects parsed findings before filtering — which is reasonable and informative. The "After filtering/capping" count reflects the `capped` list. **Not blocking — behavior is correct and informative.** + +--- -`post_findings.py:559` initializes `category_counts` with only 5 categories (`security`, `performance`, `best_practices`, `code_style`, `documentation`), and lines 668-672 only render those 5 in the PR summary's "Comment Breakdown by Category" section. Findings in the 4 new categories (`architecture`, `correctness`, `error_handling`, `testing`) will be correctly scored, gated, and posted as inline comments — but they won't appear in the summary's category breakdown. +## NOTE: Prior review recommendations status -**Not blocking.** The summary is informational. Scoring and gating use the full 9-category penalty matrix. This can be addressed in a future cleanup. +From Phase 3 review (dd0d6f0): +1. "Add Phase 3 unit tests" — not addressed in Phase 4 (out of scope). Still recommended for future. +2. "Update `_build_summary_markdown` category breakdown to include all 9 categories" — not addressed. Still recommended. +3. "Correct test count in progress.json (252 → 249)" — the Phase 4 progress entry correctly reports 270, which matches. The Phase 3 entry still says 252 (actual was 249). Minor discrepancy, not blocking. --- ## Summary -**All 5 Phase 3 tasks pass (14-18).** Phase 3 correctly adds the `testing` category with zero-weight scoring, expands `VALID_CATEGORIES` to 9 entries, trims `CATEGORY_REMAP` to 4 entries, adds penalty fields and matrix entries for all new categories, and creates both the architecture and performance review checklists with proper references from `review-pr-core.md`. The findings schema, prompt instructions, config fields, scorer logic, and fallback penalty matrix are all consistent. +**All 3 Phase 4 tasks pass (19-21).** Phase 4 correctly adds comment merging (`merge_similar_findings`) with the specified criteria (same file, ±5 lines, 0.7 similarity threshold), severity-aware keeper selection with footnotes, and a comprehensive audit trail export to `.cr/` with all 7 required sections. The merge is correctly placed between confidence filtering and capping in the pipeline. The audit trail is written after summary posting and before output construction, with graceful error handling. -Phases 1-2 have no regressions. All 249 unit tests pass. +Phases 1-3 have no regressions. All 270 unit tests pass (21 new). **Recommended (not blocking):** -1. Add Phase 3 unit tests: verify `testing` category yields 0 penalty; verify `architecture`/`correctness`/`error_handling` are NOT remapped. -2. Update `_build_summary_markdown` category breakdown to include all 9 categories (or dynamically render non-zero counts). -3. Correct the test count in `progress.json` (252 → 249). +1. Wire `risk_table_md` from `review_job.py` into the `_write_audit_trail` call so the audit file includes the actual risk classification table instead of "not available". +2. Carry forward Phase 3 recommendations: add Phase 3 unit tests, update summary markdown category breakdown to include all 9 categories.

All three criteria are AND-gated. **PASS.** +1. **Schema completeness.** Every entry has `extensions`, `config_files`, and `rules_file` fields. **PASS.** +2. **Extension mapping matches plan.** C# → `.cs`, JS → `.js/.jsx/.mjs`, TS → `.ts/.tsx`, Go → `.go`, Rust → `.rs`, C++ → `.cpp/.cc/.cxx/.c/.h/.hpp/.hxx`, etc. **PASS.** +3. **Overlay languages.** React and Android have `extensions: []` — detected via config files only, consistent with plan specification for overlay languages. **PASS.** +4. **Rules file paths.** All `rules_file` values point to `commands/lang-rules/.md` matching the actual file locations. **PASS.** -2. **Severity prioritization.** `severity_order` dict ranks `critical=0, warning=1, suggestion=2`. When merging, the finding with the lower rank (higher severity) becomes the keeper. If `fj` has higher severity than `current`, the code swaps to keep `fj` and footnotes `current`. **PASS.** +--- -3. **Footnote format.** Merged findings append `"\n\n*(Also flagged at line {n}: {merged_title})*"` — matches plan specification. **PASS.** +## Task 23: Stack Detector -4. **Cross-file non-merge.** Findings are grouped by `f.file` into separate buckets — findings on different files never encounter each other in the merge loop. **PASS.** +**PASS.** `src/stack_detector.py` created with `StackProfile` dataclass and `detect()` function. -5. **Pipeline placement.** Merge runs at step 3b (`post_findings.py:1061-1063`), after `filter_by_confidence` and before `cap_findings`. This is the correct position per the plan: "between the existing `filter_by_confidence` step and `cap_findings` step". Skipped for verify-only mode. **PASS.** +1. **StackProfile dataclass.** Fields `languages: list[str]`, `frameworks: dict[str, dict[str, str]]`, `detected_from: list[str]` — matches plan specification exactly. **PASS.** +2. **Config file parsers.** 11 language detectors implemented: `_detect_csharp` (XML `.csproj` parsing for `TargetFramework` + `PackageReference`), `_detect_node` (JSON `package.json` for React/Angular/Vue/TS/Next + `tsconfig.json`), `_detect_python` (requirements.txt, pyproject.toml, Pipfile), `_detect_java` (pom.xml with Maven namespace handling, build.gradle/kts), `_detect_go`, `_detect_rust`, `_detect_cpp`, `_detect_swift`, `_detect_android`, `_detect_ruby`, `_detect_php`. **PASS.** +3. **C# .NET 8.0 test.** Unit test `test_detect_csharp_net8` confirms: `.csproj` with `net8.0` → `languages=["csharp"]`, `frameworks={"csharp": {"dotnet": "8.0"}}`. Matches the "Done when" criterion exactly. **PASS.** +4. **Monorepo limitation.** Code comment at module docstring: "Monorepo limitation: only root-level configs are parsed (per-directory profiles deferred to a future sprint)." **PASS.** +5. **Error handling.** Every parser wraps in try/except, logs to debug, and continues gracefully. No parser failure crashes the detection pipeline. **PASS.** +6. **XML namespace handling in pom.xml.** Tries both with and without Maven 4.0 namespace for `maven.compiler.source` and `java.version`. **PASS.** +7. **tsconfig.json comment stripping.** Handles JSON-with-comments by stripping `//` and `/* */` before parsing. **PASS.** -6. **Edge case: sorted-by-line early exit.** The `break` at line 311 (`if abs(fj.line - anchor_line) > 5: break`) is correct because findings are sorted by line — once we exceed the 5-line window, no further candidates can match. **PASS.** +--- -7. **No new dependencies.** Uses `difflib.SequenceMatcher` (stdlib) — no new packages. **PASS.** +## Task 24: Version-aware Rules Files (Batch 1) -**Test coverage (10 tests):** -- `test_nearby_similar_findings_on_same_file_merge` — lines 10, 12, 50 → two merge, one stays. **PASS.** -- `test_different_files_do_not_merge` — cross-file identical findings stay separate. **PASS.** -- `test_keeps_higher_severity_finding` — suggestion + critical → critical survives. **PASS.** -- `test_footnote_added_to_merged_finding` — "Also flagged at line" present. **PASS.** -- `test_line_gap_exactly_5_merges` — boundary test at 5. **PASS.** -- `test_line_gap_of_6_does_not_merge` — boundary test at 6. **PASS.** -- `test_dissimilar_findings_on_same_file_nearby_lines_do_not_merge` — different titles/messages. **PASS.** -- `test_empty_input_returns_empty` — edge case. **PASS.** -- `test_single_finding_returned_unchanged` — edge case. **PASS.** -- `test_third_finding_far_away_not_merged` — mixed near+far. **PASS.** +**PASS.** All 8 files created in `commands/lang-rules/`: -Done criteria: "Given 3 findings on same file with lines 10, 12, 50 — the first two merge, the third stays separate.

Examples: C# covers `async void` antipattern, SQL injection in EF Core raw SQL, CORS wildcard, anti-forgery tokens. Python covers mutable defaults, command injection, bare except, SQL injection. **PASS.** -## Task 20: Audit trail export - -**PASS.** `_write_audit_trail()` added at `post_findings.py:878-1016`. +--- -1. **File path and timestamp.** `Path(workspace) / ".cr" / f"review_{pr_id}_{now:%Y%m%d_%H%M%S}.md"` — matches plan specification exactly. `cr_dir.mkdir(parents=True, exist_ok=True)` creates the directory if needed. **PASS.** +## Task 25: Version-aware Rules Files (Batch 2) -2. **All 7 required sections present:** +**PASS.** All 7 files created in `commands/lang-rules/`: - | Section | Lines | Content | Verdict | - |---------|-------|---------|---------| - | PR Metadata | 892-908 | PR ID, repo, VCS, review modes, optional branch/author/title from `pr_details` | **PASS** | - | Score Breakdown | 910-928 | Overall rating, total penalty, per-category penalty table | **PASS** | - | Files Reviewed | 930-941 | Coverage display, coverage %, list of unreviewed files | **PASS** | - | Findings | 943-962 | Raw vs capped counts, severity/category/file/line/title/confidence table, filtered-out section | **PASS** | - | Token Usage | 964-979 | Model, input/output/total tokens, duration, estimated cost | **PASS** | - | Risk Classification | 981-986 | Injects `risk_table_md` parameter or "not available" fallback | **PASS** | - | Gate Decision | 988-995 | PASSED/FAILED result, reasons list | **PASS** | +| File | Checklist Items | Version Sections | +|------|----------------|-----------------| +| rust.md | 30 | All Versions, Edition 2021, Edition 2024 | +| cpp.md | 30 | Verified present | +| swift.md | 30 | Verified present | +| android.md | 30 | Verified present | +| ruby.md | 30 | Verified present | +| php.md | 30 | Verified present | +| sql.md | 30 | Verified present | -3. **Pipeline placement.** Audit trail is written at step 13b (`post_findings.py:1238-1252`), after summary posting and before output construction. This is the correct position per the plan: "after the summary posting step, before the output construction." **PASS.** +1. **Minimum item count.** All 7 files have >= 30 checklist items. **PASS.** +2. **Spot-check rust.md.** Three version sections (All Versions, Edition 2021, Edition 2024). Rules cover `unwrap()` in library code, `unsafe` block documentation, `Arc>` over-use, Edition 2024 `gen` blocks and `async` closures. **PASS.** -4. **Error handling.** Write failure is caught with a generic `except Exception` and logged via `_eprint` — returns `None` instead of crashing the pipeline. **PASS.** +--- -5. **`risk_table_md` not wired in the `run()` call.** The `_write_audit_trail` call at line 1239 does not pass `risk_table_md`, so it defaults to `""` and the audit file says "*(Risk classification not available for this review)*". The risk table is computed in `review_job.py` (Phase 2) but not propagated to `post_findings.py`. **NOTE — not blocking.** The function signature accepts it and the section renders correctly in both cases. Wiring it through requires threading the risk table from `review_job.py` through the findings pipeline, which is integration work beyond Phase 4 scope. The audit file still contains all 7 section headers. +## Task 26: Integration into review_job.py -**Test coverage (11 tests):** -- `test_audit_file_is_created_in_cr_directory` — `.cr/` directory creation. **PASS.** -- `test_audit_file_timestamp_format` — regex `review_42_\d{8}_\d{6}\.md`. **PASS.** -- `test_audit_file_contains_pr_metadata_section` — PR ID, repo name. **PASS.** -- `test_audit_file_contains_score_breakdown_section` — score, penalty. **PASS.** -- `test_audit_file_contains_files_reviewed_section` — coverage %. **PASS.** -- `test_audit_file_contains_findings_section` — severity, category. **PASS.** -- `test_audit_file_contains_token_usage_section` — token counts, model. **PASS.** -- `test_audit_file_contains_risk_classification_section` — section header. **PASS.** -- `test_audit_file_contains_gate_decision_section` — FAILED, reasons. **PASS.** -- `test_audit_written_during_dry_run` — end-to-end via `pf.run()` in dry-run. **PASS.** -- `test_audit_file_contains_all_required_sections` — all 7 sections present. **PASS.** +**PASS.** Three integration points implemented correctly. -Done criteria: "Audit file written to `.cr/` with correct timestamp format; contains all expected sections (PR metadata, score breakdown, files reviewed, findings, token usage, risk table, gate decision)." — **all met.** +1. **`_build_config_section` flow.** Method at `review_job.py:602-641`. Loads `.codereview.md` first — if present, `has_codereview_md = True` and auto-detection is skipped (line 627: `if not has_codereview_md`). If no `.codereview.md`, calls `_build_lang_rules_section()`. **PASS — existing override behavior preserved.** ---- +2. **`_build_lang_rules_section` implementation.** Method at `review_job.py:643-697`. Calls `stack_detector.detect(workspace)`, iterates detected languages, loads `commands/lang-rules/.md`, filters via `_filter_rules_for_version()`, and injects into prompt with "Auto-detected Stack" header and framework summary. **PASS.** -## Task 21 VERIFY: Test Suite +3. **`_filter_rules_for_version` + `_version_heading_matches`.** At `review_job.py:36-126`. "All Versions" sections always included. Version-specific sections (e.g., ".NET 8+") included only when detected version >= required version. Comparison uses tuple-based integer comparison. Unknown versions default to inclusion (safe fallback). **PASS.** -**PASS.** `python -m pytest tests/ -v` — **270 passed, 13 skipped, 0 failures** in 2.61s. The 13 skipped are integration tests (expected — mocked unit tests only constraint). +4. **`file_filter.py` registry lookup.** `load_registered_extensions()` at line 43 loads extensions from `languages.yml` via `yaml.safe_load`. `filter_changed_files()` at line 79 uses registry when available, falls back to blacklist when `languages.yml` is missing/broken. **PASS.** -- 21 new Phase 4 tests in `tests/unit/test_phase4_noise_audit.py` (10 merge + 11 audit). -- All 249 Phase 1-3 tests continue to pass — no regressions. -- Doer's progress.json reports 270 — matches actual count. **PASS.** +5. **`review-pr-core.md` Step 1 update.** Line 18: "If `.codereview.md` exists, load it — project-specific rules always take precedence. Otherwise, the system reads your project config files (package.json, *.csproj, go.mod, etc.) to detect exact framework versions and injects version-appropriate review rules automatically." **PASS.** --- -## NOTE: `all_raw_findings` parameter uses post-parse list +## Task 27 VERIFY: 302 Unit Tests -`_write_audit_trail` receives `findings_file.findings` as `all_raw_findings` (line 1242). At this point, `findings_file.findings` is the parsed list, not the pre-filter list. After step 3 (confidence filtering) and step 3b (merge), the `after_confidence` variable holds the filtered+merged list, but `findings_file.findings` is the original parsed findings (pre-filter, pre-merge). This means the audit trail's "Total raw" count reflects parsed findings before filtering — which is reasonable and informative. The "After filtering/capping" count reflects the `capped` list. **Not blocking — behavior is correct and informative.** +**PASS.** `python -m pytest tests/ -v` completed in 23.25s: **302 passed, 13 skipped, 0 failed.** ---- +32 new Phase 5 tests in `tests/unit/test_phase5_lang_intelligence.py`: +- `TestStackDetector` (11 tests): .NET 8 detection, .NET 6 detection, EF Core version, TypeScript from package.json, React overlay, Python from requirements.txt, Python version from pyproject, Go, Rust edition, empty workspace, dataclass defaults. +- `TestLangRulesFiles` (5 tests): all 15 files exist, each has >= 30 checklist items, each has version sections, languages.yml has 15 entries, entries have required fields. +- `TestVersionFiltering` (8 tests): "All Versions" always included, .NET 8+ included for .NET 8, .NET 8+ excluded for .NET 6, Python 3.10+ included for 3.12, Python 3.10+ excluded for 3.8, unknown version includes section, real csharp.md tests for both .NET 8 and .NET 6. +- `TestFileFilterRegistryVerify` (3 tests): .cs reviewed when csharp registered, .json skipped when not registered, .codereview.md skipped. -## NOTE: Prior review recommendations status +**Test quality assessment.** Coverage is meaningful: +- Stack detector tested with real file parsing (csproj XML, package.json, pyproject.toml, go.mod, Cargo.toml) via `tmp_path` fixtures. +- Version filtering tested at both unit level (synthetic rules) and integration level (real csharp.md file). +- File filter registry tested with the actual `languages.yml` file. +- Edge cases covered: empty workspace, unknown versions, overlay languages. -From Phase 3 review (dd0d6f0): -1. "Add Phase 3 unit tests" — not addressed in Phase 4 (out of scope). Still recommended for future. -2. "Update `_build_summary_markdown` category breakdown to include all 9 categories" — not addressed. Still recommended. -3. "Correct test count in progress.json (252 → 249)" — the Phase 4 progress entry correctly reports 270, which matches. The Phase 3 entry still says 252 (actual was 249). Minor discrepancy, not blocking. +**NOTE:** The import `import stack_detector as sd` at `review_job.py:646` is a lazy import inside the method — consistent with the codebase's bare-module import pattern (`from config import Settings`, etc.) which assumes `src/` is on `sys.path`. This works at runtime and in tests. No issue. --- ## Summary -**All 3 Phase 4 tasks pass (19-21).** Phase 4 correctly adds comment merging (`merge_similar_findings`) with the specified criteria (same file, ±5 lines, 0.7 similarity threshold), severity-aware keeper selection with footnotes, and a comprehensive audit trail export to `.cr/` with all 7 required sections. The merge is correctly placed between confidence filtering and capping in the pipeline. The audit trail is written after summary posting and before output construction, with graceful error handling. - -Phases 1-3 have no regressions. All 270 unit tests pass (21 new). +**All 6 Phase 5 tasks (22–27) meet their "Done when" criteria. No regressions in Phases 1–4. 302 tests pass, 0 fail. Verdict: APPROVED.** -**Recommended (not blocking):** -1. Wire `risk_table_md` from `review_job.py` into the `_write_audit_trail` call so the audit file includes the actual risk classification table instead of "not available". -2. Carry forward Phase 3 recommendations: add Phase 3 unit tests, update summary markdown category breakdown to include all 9 categories. +Phase 5 delivers a complete language intelligence system: 15-language registry in YAML, stack detector parsing 13 config file formats, 15 version-aware rules files with 30–40 checklist items each, version-gated filtering, and clean integration into the review pipeline with `.codereview.md` override preservation. Test coverage is comprehensive with 32 new tests covering detection, filtering, and registry modes.

Findings on deleted files immediately get `status="not_relevant"` with reason "File was deleted or removed from the repository." No LLM call made. Unit test `test_deleted_file_all_findings_not_relevant` confirms. **PASS.** ---- +2. **Unchanged files -> still_present (no LLM).** If a file is not in the diff output (neither modified, deleted, nor renamed), all its findings get `status="still_present"`. Unit test `test_unchanged_file_all_findings_still_present_no_llm` confirms `_call_llm_for_verification` is never called. **PASS.** -## Task 23: Stack Detector +3. **Modified files -> file-level LLM verification (one call per file).** `_verify_single_file` reads the full file content, builds a verification prompt with all findings for that file, and makes one `_call_llm_for_verification` call. Unit test `test_modified_file_3_findings_one_llm_call` confirms `mock_llm.call_count == 1` for 3 findings on the same file. **PASS.** -**PASS.** `src/stack_detector.py` created with `StackProfile` dataclass and `detect()` function. +4. **15-file cap with overflow batching.** `_INDIVIDUAL_FILE_CAP = 15` and `_BATCH_FILE_SIZE = 5`. First 15 files processed individually, overflow files batched in groups of 5 (each still gets its own LLM call within the batch). Unit test `test_20_modified_files_respects_cap` confirms 20 total calls for 20 files. **PASS.** -1. **StackProfile dataclass.** Fields `languages: list[str]`, `frameworks: dict[str, dict[str, str]]`, `detected_from: list[str]` — matches plan specification exactly. **PASS.** -2. **Config file parsers.** 11 language detectors implemented: `_detect_csharp` (XML `.csproj` parsing for `TargetFramework` + `PackageReference`), `_detect_node` (JSON `package.json` for React/Angular/Vue/TS/Next + `tsconfig.json`), `_detect_python` (requirements.txt, pyproject.toml, Pipfile), `_detect_java` (pom.xml with Maven namespace handling, build.gradle/kts), `_detect_go`, `_detect_rust`, `_detect_cpp`, `_detect_swift`, `_detect_android`, `_detect_ruby`, `_detect_php`. **PASS.** -3. **C# .NET 8.0 test.** Unit test `test_detect_csharp_net8` confirms: `.csproj` with `net8.0` → `languages=["csharp"]`, `frameworks={"csharp": {"dotnet": "8.0"}}`. Matches the "Done when" criterion exactly. **PASS.** -4. **Monorepo limitation.** Code comment at module docstring: "Monorepo limitation: only root-level configs are parsed (per-directory profiles deferred to a future sprint)." **PASS.** -5. **Error handling.** Every parser wraps in try/except, logs to debug, and continues gracefully. No parser failure crashes the detection pipeline. **PASS.** -6. **XML namespace handling in pom.xml.** Tries both with and without Maven 4.0 namespace for `maven.compiler.source` and `java.version`. **PASS.** -7. **tsconfig.json comment stripping.** Handles JSON-with-comments by stripping `//` and `/* */` before parsing. **PASS.** +5. **Blast radius checks.** `_annotate_blast_radius` checks fixed findings with `severity="critical"` or `category="architecture"` against the graph store. If dependents exist, appends informational note. Does not change verdict. Unit tests confirm annotation for critical findings with dependents, no annotation for still_present, and no annotation when graph returns empty. **PASS.** ---- +6. **ADO thread posting.** `_post_results_to_ado` posts to ADO threads: "Verified fixed" for fixed, "File deleted/removed" for not_relevant, and "Still present" via `_post_still_present_reply` for still_present findings. **PASS.** -## Task 24: Version-aware Rules Files (Batch 1) +7. **Default to still_present on failure.** `_map_llm_results_to_verifications` defaults to `still_present` when: LLM returns empty list, LLM returns None, finding index missing from LLM results, or unrecognized status string. Four separate unit tests confirm all these paths. **PASS.** -**PASS.** All 8 files created in `commands/lang-rules/`: +8. **review-pr-core.md Step 6 updated.** Step 6 now reads "Fix verification is handled automatically by the system after your review completes." No sub-steps 6a/6b/6c/6d. No "Write fix_verifications" instruction. Unit tests `TestReviewPrCoreStep6` confirm all three assertions. **PASS.** -| File | Checklist Items | Version Sections | -|------|----------------|-----------------| -| csharp.md | 40 | All Versions, .NET 6+, .NET 8+, EF Core 6+, ASP.NET Core | -| javascript.md | 30 | Verified present | -| typescript.md | 30 | Verified present | -| react.md | 30 | Verified present | -| python.md | 30 | All Versions, Python 3.8+, Python 3.10+, Python 3.12+ | -| java.md | 30 | Verified present | -| kotlin.md | 30 | Verified present | -| go.md | 30 | Verified present | +9. **Renamed file handling.** `_get_file_statuses` parses `R100` lines, maps old path to new path in `renamed_map`, and adds the new path to `modified` set. The main loop remaps findings via `renamed_map.get(file_path, file_path)` before checking modified set. Unit test `test_renamed_file_detected` confirms. **PASS.** -1. **Minimum item count.** All files have >= 30 checklist items. csharp.md leads with 40. **PASS.** -2. **Version sections.** Spot-checked csharp.md and python.md in detail. csharp.md has 5 version sections matching plan (All Versions, .NET 6+, .NET 8+, EF Core 6+, ASP.NET Core). python.md has 4 version sections (All Versions, Python 3.8+, Python 3.10+, Python 3.12+). **PASS.** -3. **Content quality.** Rules focus on real bugs and security issues, not formatting preferences. Examples: C# covers `async void` antipattern, SQL injection in EF Core raw SQL, CORS wildcard, anti-forgery tokens. Python covers mutable defaults, command injection, bare except, SQL injection. **PASS.** +**NOTE (non-blocking):** The `_verify_files_with_llm` overflow batching loop iterates files individually within each batch of 5, calling `_verify_single_file` per file. The batching structure groups calls but doesn't combine multiple files into a single LLM call. This is functionally correct and arguably better for reliability (one file per call), but the 15-file cap + batching described in the docstring ("overflow batched 5 per call") is slightly misleading — it's "batched 5 per iteration" with one call per file.

Subject: [PATCH 27/31] feat(review): CSS support, lang-rules always injected, multi-category scan fixes MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Lang-rules injection: - Always inject lang-rules alongside .codereview.md (not either/or) - Detect languages from changed file extensions per batch (not workspace config) - CSS/SCSS/LESS registered in languages.yml with 53-item css.md ruleset Lang-rules expanded: - csharp: +LINQ section, .NET Framework 4.x, EF 6.x, Web API 5.x - java: +Java 8+ section (Stream, Optional, CompletableFuture, DateTime) - javascript: +12 security/correctness rules (fetch errors, FormData, prototype pollution) - react: +Accessibility (10 items), +Testing (5 items), expanded React 16 guards - go: +6 rules (pointer receivers, context cancel, http timeout, race detector) - typescript: fixed duplicate TS 4.x section, +5 rules Multi-category scan fixes: - review-scan.md: per-file checklist structure forces all categories per file - System prompt: detailed category hints with specific patterns to look for - Examples: 5 multi-category examples (security, performance, architecture, error_handling, correctness) - scoring.md + review-verify.md: corrected confidence threshold docs (0.7 → 0.5 matching code) Results: security and error_handling findings now appearing (was always 0 before) ---
