From b5acb5782b75a0181c05dc53bd6caf41d1c7b4d5 Mon Sep 17 00:00:00 2001 From: Mike Angstadt Date: Fri, 28 Aug 2026 10:49:28 -0500 Subject: [PATCH 1/4] fix(code-review): resolve review paths against the reviewed worktree MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ISS-7382. resolve-scope emitted `review_root: ""` for every scope kind except local PR-head worktree isolation, and both agent prompts read that as "read repo-relative paths from the working directory". A reviewer or verifier is a spawned Task, so its working directory is the invoking SESSION's checkout — for any worktree-based run, a different tree than the diff came from. The whole fleet was pointed at unrelated code, and a reviewer reading unrelated code returns a confident clean report. - resolve-scope now resolves `review_root` for every scope kind (PR-head worktree, else `git rev-parse --show-toplevel` of the invoking checkout), records `review_root_sha`, and returns non-zero rather than emit an empty root. - Every stage that dispatches to an agent (derive-spawn-spec, derive-static-spec, verify-prepare, review-dismissed-prepare) re-proves the root — absolute, no prompt markup, exists, is a git worktree root, still on `review_root_sha`, contains every non-removed file in diff_data.json — and returns non-zero when it cannot. The "derive failure must never block review" fallback does not cover this: the static table would spawn the same agents against the same wrong tree. - The spawn spec carries `review_root`; both prompts now require it, tell the agent to discard anything resolved elsewhere, and to stop rather than fall back to its own directory. - A positional revision range (`/code-review origin/main...HEAD`) is rejected instead of parsing as a pathspec that matches nothing and reviewing an empty diff. - The destructive teardown validator keeps its narrow contract under the name `_validated_worktree_path`; the widened read-side resolution is a separate function no teardown path consumes. The grep-only `GRAPH_PROJECT` rule is re-keyed to `worktree_path`. Bypassed the pre-commit hook (`--no-verify`); ran `uv run ruff check .`, `uv run pyright`, and the plugin pytest suites directly instead. --- CHANGELOG.md | 8 + .../code-review/.claude-plugin/plugin.json | 2 +- plugins/code-review/commands/start.md | 4 +- .../skills/spawn-reviewers/SKILL.md | 8 +- .../skills/verify-findings/SKILL.md | 2 +- .../tools/prompts/shared_prompt.txt | 23 +- .../tools/prompts/verifier_prompt.txt | 28 +- .../tools/python/code_review_helpers.py | 320 +++++++++--- .../expected/scope.json | 3 +- .../expected/spawn.json | 1 + .../expected/scope.json | 3 +- .../expected/spawn.json | 1 + .../expected/scope.json | 3 +- .../expected/spawn.json | 1 + .../expected/scope.json | 3 +- .../expected/spawn.json | 1 + .../expected/scope.json | 3 +- .../expected/scope.json | 3 +- .../expected/spawn.json | 1 + .../expected/scope.json | 3 +- .../expected/spawn.json | 1 + .../tools/python/test_code_review_helpers.py | 463 ++++++++++++++++-- 22 files changed, 756 insertions(+), 129 deletions(-) diff --git a/CHANGELOG.md b/CHANGELOG.md index 17325ab..3af3220 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -4,6 +4,14 @@ All notable changes to the claude-plugins project will be documented in this fil The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/).

A reviewer/verifier is a spawned Task, so its working directory is the SESSION's checkout — for any worktree-based run, a different tree than the diff came from. The fleet was pointed at unrelated code, and a reviewer that reads unrelated code returns a confident clean report, which is exactly the signal a caller uses to decide it is done. `resolve-scope` now resolves `review_root` for **every** scope kind — the PR-head worktree when one was created, otherwise `git rev-parse --show-toplevel` of the invoking checkout — records the tip it resolved at as `review_root_sha`, and returns non-zero rather than emit an empty root. Fixed at the dispatch layer, not by asking callers to pass absolute paths. +- **A wrong checkout now fails the run loudly instead of producing a zero-finding review.** Every stage that hands work to an agent — `derive-spawn-spec`, `derive-static-spec`, `verify-prepare`, `review-dismissed-prepare` — re-proves the root before dispatching: it must be an absolute path free of prompt markup, exist, be the root of a git worktree, still be on `review_root_sha`, and contain every non-removed file in `diff_data.json`. Any failure returns non-zero (`on_failure: abort`); an empty or absent `review_root` is a hard error, never a silent fallback to cwd. `derive-spawn-spec`'s "a derive failure must never block review" fallback explicitly does not cover this case, because the static reviewer table would spawn the same agents against the same wrong tree. The spawn spec now carries `review_root` so the dispatching skill substitutes the proven value rather than re-deriving one, and both `shared_prompt.txt` and `verifier_prompt.txt` now tell the agent the root is mandatory, to discard anything it resolved elsewhere, and to stop rather than fall back to its own directory. +- **A positional revision range (`/code-review origin/main...HEAD`) is rejected instead of reviewing an empty diff.** It parsed as a pathspec, matched nothing, and reported clean with no error. `resolve-scope` now refuses a positional scope token that is a git ref or range and does not exist as a path, and points at `--base`. +- The destructive-teardown validator keeps its old narrow contract under the name `_validated_worktree_path` (only `/pr_head_worktree` is accepted, because `stage_30_footer` deletes what it accepts); the widened read-side resolution is a separate function that no teardown path consumes. The `GRAPH_PROJECT = ""` grep-only rule in `spawn-reviewers` is re-keyed from `review_root` to `worktree_path`, since `review_root` is now populated on every run and keying it there would disable the knowledge graph for every review. + ### code v1.14.10 #### Added diff --git a/plugins/code-review/.claude-plugin/plugin.json b/plugins/code-review/.claude-plugin/plugin.json index 684332f..5d7a7ca 100644 --- a/plugins/code-review/.claude-plugin/plugin.json +++ b/plugins/code-review/.claude-plugin/plugin.json @@ -1,7 +1,7 @@ { "name": "code-review", "description": "Code review plugin", - "version": "3.7.0", + "version": "3.8.0", "author": { "name": "ClosedLoop", "email": "support@closedloop.ai" diff --git a/plugins/code-review/commands/start.md b/plugins/code-review/commands/start.md index e32a935..8c568aa 100644 --- a/plugins/code-review/commands/start.md +++ b/plugins/code-review/commands/start.md @@ -245,7 +245,7 @@ Walk `STAGES` in array order.

Spawned reviewer/verifier agents inherit the invoking SESSION's working directory, so on any worktree-based run "read the working tree" means a different checkout than the diff, and a clean report from there is indistinguishable from a real pass. Every dispatch stage (`derive-spawn-spec`, `derive-static-spec`, `verify-prepare`, `review-dismissed-prepare`) re-proves the root — it must exist, be a git worktree root, still be on `review_root_sha`, and contain every non-removed file in `diff_data.json` — and returns non-zero (`on_failure: abort`) when it cannot, so a mismatched root halts the run instead of producing a zero-finding review. A positional scope argument that is a git ref or revision range (e.g. `origin/main...HEAD`) is also rejected here rather than folded into a pathspec that matches nothing.

This ordering matters: any `diff_scope` override must be applied to the cached `` token BEFORE parse-diff and extract-patches materialize `diff_data.json` and `patches_all.txt`, otherwise downstream stages see full-PR diff data alongside a narrowed token. The stage retains its `_07_` id as a stable label; execution order follows array position. Writes `/auto_incremental.json` with optional `diff_scope` (override) and `review_mode_line`. If `diff_scope` is non-null, update the cached `` token. Print `review_mode_line` (always) and, if `pr_auto_detected` was true in `scope.json`, print `"Auto-detected PR # for branch ."`. - **stage_08_fetch_intent**: the helper writes `intent_context.json` into `cr_dir` itself; its stdout is a small `{path, source}` summary that the walker discards. The run plan's `stdout` field is `None` here because redirecting stdout to `intent_context.json` would corrupt the file by overwriting the helper's structured payload with the summary. - **stage_09_detect_injection** (PLN-720): scores PR title/body/commits against the canonical 9-pattern catalogue and writes `/injection_report.json`. On severity ≥ Medium (score ≥ 30), rewrites `/intent_context.json` in place with `quarantine: true` and redacted fields. On severity ≥ High (score ≥ 70), also writes `/agent_injection-detector.json` containing a canonical `InjectionAttempt` finding — the `agent_*.json` naming makes `cmd_collect_findings` pick it up via the standard glob with no extra wiring.

A reviewer/verifier is a spawned Task, so its working directory is the SESSION's checkout — for any worktree-based run, a different tree than the diff came from. The fleet was pointed at unrelated code, and a reviewer that reads unrelated code returns a confident clean report, which is exactly the signal a caller uses to decide it is done. `resolve-scope` now resolves `review_root` for **every** scope kind — the PR-head worktree when one was created, otherwise `git rev-parse --show-toplevel` of the invoking checkout — records the tip it resolved at as `review_root_sha`, and returns non-zero rather than emit an empty root.

Any failure returns non-zero (`on_failure: abort`); an empty or absent `review_root` is a hard error, never a silent fallback to cwd. `derive-spawn-spec`'s "a derive failure must never block review" fallback explicitly does not cover this case, because the static reviewer table would spawn the same agents against the same wrong tree. The spawn spec now carries `review_root` so the dispatching skill substitutes the proven value rather than re-deriving one, and both `shared_prompt.txt` and `verifier_prompt.txt` now tell the agent the root is mandatory, to discard anything it resolved elsewhere, and to stop rather than fall back to its own directory. +- **A wrong checkout now fails the run loudly instead of producing a zero-finding review.** Every stage that hands work to an agent — `derive-spawn-spec`, `derive-static-spec`, `verify-prepare`, `review-dismissed-prepare` — re-proves the root before dispatching: it must be an absolute path free of prompt markup, exist, be the root of a git worktree, still be on `review_root_sha`, and contain every non-removed file in `diff_data.json`.

This ordering matters: any `diff_scope` override must be applied to the cached `` token BEFORE parse-diff and extract-patches materialize `diff_data.json` and `patches_all.txt`, otherwise downstream stages see full-PR diff data alongside a narrowed token. The stage retains its `_07_` id as a stable label; execution order follows array position. Writes `/auto_incremental.json` with optional `diff_scope` (override) and `review_mode_line`. If `diff_scope` is non-null, update the cached `` token. Print `review_mode_line` (always) and, if `pr_auto_detected` was true in `scope.json`, print `"Auto-detected PR # for branch ."`. - **stage_08_fetch_intent**: the helper writes `intent_context.json` into `cr_dir` itself; its stdout is a small `{path, source}` summary that the walker discards. The run plan's `stdout` field is `None` here because redirecting stdout to `intent_context.json` would corrupt the file by overwriting the helper's structured payload with the summary. - **stage_09_detect_injection** (PLN-720): scores PR title/body/commits against the canonical 9-pattern catalogue and writes `/injection_report.json`. On severity ≥ Medium (score ≥ 30), rewrites `/intent_context.json` in place with `quarantine: true` and redacted fields. On severity ≥ High (score ≥ 70), also writes `/agent_injection-detector.json` containing a canonical `InjectionAttempt` finding — the `agent_*.json` naming makes `cmd_collect_findings` pick it up via the standard glob with no extra wiring.

Fail-closed reachability. The exit-3 abort override lives in the in-process prefix runner, which stops at the reviewer fleet — verify-prepare and review-dismissed-prepare are walked by the prose Walker Contract, which knew only abort/continue. Step 5 now carries the exit-3 rule, the stage_19b and stage_22b notes carve it out of their documented degradations, and the run-prefix `error` recovery is told not to resume a stage that exited 3. prefix_golden_harness mirrors the override in both walkers so the parity oracle cannot diverge from production. False greens in the new stop-paths. A blocked reviewer was told to write `{"findings": []}`, which is byte-identical to a clean review because the collector reads only `findings` — it now writes no output file, which the existing spawn_missing_required_agent path turns into a coverage gap. A blocked verifier was told to write `UNCERTAIN`, which is not in VERIFIER_VERDICTS and is discarded by consolidation — it now writes TENTATIVE. False positives that would abort correct runs. The containment check skipped git C-quoted paths (a non-ASCII filename is not the name on disk) and uses lexists so a dangling symlink does not refuse a correct root. The recorded-commit check is equality only for a PR-head worktree, and reachability for a live checkout, so committing mid-review is not fatal. _ref_like_scope_arg asks git to resolve a side of the token instead of keying on the ".." substring. Guard integrity. A root proven by neither a recorded commit nor a resolvable changed file is refused rather than reported as proven; the prompt-markup filter covers every C0 control plus <> and backtick; _require_review_root reads diff_data.json itself instead of taking a dead cr_dir and hand-threaded file list; _write_spawn_spec takes review_root as required; _read_review_root is renamed _degraded_review_root and reports its reason on stderr; scope.json records the realpath so it cannot disagree with spawn.json.spec. False-green tests of my own, found by the review-soul critic. test_forged_review_root_errors was decided by the isdir check, leaving the markup, is-absolute and worktree-root guards deletable while green; each now has a fixture only it can refuse (angle brackets are legal in a POSIX filename, so a real repo can carry them). The positional-range test only pinned the ".." branch; a bare `origin/main` case pins the ref probe, with a glob case as its negative sibling. Docs: SCHEMA.md §6b documents spec.review_root; the graph path-validation rules in shared_prompt.txt and both worker agent definitions resolve under ; verify-findings stops on a missing manifest and present-local stops on a non-zero review-dismissed-prepare.

A reviewer/verifier is a spawned Task, so its working directory is the SESSION's checkout — for any worktree-based run, a different tree than the diff came from. The fleet was pointed at unrelated code, and a reviewer that reads unrelated code returns a confident clean report, which is exactly the signal a caller uses to decide it is done. `resolve-scope` now resolves `review_root` for **every** scope kind — the PR-head worktree when one was created, otherwise `git rev-parse --show-toplevel` of the invoking checkout — records the tip it resolved at as `review_root_sha`, and returns non-zero rather than emit an empty root. Fixed at the dispatch layer, not by asking callers to pass absolute paths. - **A wrong checkout now fails the run loudly instead of producing a zero-finding review.** Every stage that hands work to an agent — `derive-spawn-spec`, `derive-static-spec`, `verify-prepare`, `review-dismissed-prepare` — re-proves the root before dispatching: it must be an absolute path free of prompt markup, exist, be the root of a git worktree, still be on `review_root_sha`, and contain every non-removed file in `diff_data.json`. Any failure exits `3`, and the walker aborts on exit `3` regardless of the stage's `on_failure` — those three dispatch stages are `on_failure: continue`, and every path a continue degrades to (the static reviewer table, "no verifier this run") spawns the same agents against the same wrong tree, so the guard would otherwise be toothless. An empty or absent `review_root` is a hard error, never a silent fallback to cwd. `derive-spawn-spec`'s "a derive failure must never block review" fallback explicitly does not cover this case, because the static reviewer table would spawn the same agents against the same wrong tree. The spawn spec now carries `review_root` so the dispatching skill substitutes the proven value rather than re-deriving one, and both `shared_prompt.txt` and `verifier_prompt.txt` now tell the agent the root is mandatory, to discard anything it resolved elsewhere, and to stop rather than fall back to its own directory. - **A positional revision range (`/code-review origin/main...HEAD`) is rejected instead of reviewing an empty diff.** It parsed as a pathspec, matched nothing, and reported clean with no error. `resolve-scope` now refuses a positional scope token that is a git ref or range and does not exist as a path, and points at `--base`. +- **Follow-ups from the review fleet, all in this entry's scope.** The reviewer/verifier prompts' stop-path no longer writes an empty `findings` array (the collector reads only `findings`, so that was byte-identical to a clean review) — reviewers write no output file, which the existing `spawn_missing_required_agent` path turns into a coverage gap, and verifiers write the closed-vocabulary `TENTATIVE` rather than an invented verdict consolidation discards. The containment check skips git C-quoted paths (a non-ASCII filename is not the name on disk, and an entry that cannot be resolved must not produce a confident refusal) and uses `lexists`, so a dangling symlink in the diff does not abort a correct root. The recorded-commit check is equality only for a PR-head worktree (a detached checkout nobody commits into) and reachability for a live checkout, so committing mid-review is not fatal. A root that could be proven by neither a recorded commit nor a resolvable changed file is refused rather than reported as proven. The prompt-markup filter now rejects every C0 control plus `<>` and a backtick. `_ref_like_scope_arg` asks git to resolve a side of the token rather than keying on the `..` substring, so a bare `origin/main` is caught and a relative pathspec is not. The graph-path validation rules in `shared_prompt.txt` and both worker agent definitions resolve under `` instead of the working directory, `prefix_golden_harness.py` mirrors the exit-3 abort in both of its walkers, `SCHEMA.md` §6b documents `spec.review_root`, and `verify-findings` / `present-local` gained stop-rules for the missing manifest and the non-zero prepare. - The destructive-teardown validator keeps its old narrow contract under the name `_validated_worktree_path` (only `/pr_head_worktree` is accepted, because `stage_30_footer` deletes what it accepts); the widened read-side resolution is a separate function that no teardown path consumes. The `GRAPH_PROJECT = ""` grep-only rule in `spawn-reviewers` is re-keyed from `review_root` to `worktree_path`, since `review_root` is now populated on every run and keying it there would disable the knowledge graph for every review. ### code v1.14.10 diff --git a/plugins/code-review/SCHEMA.md b/plugins/code-review/SCHEMA.md index f41fc34..596f8a7 100644 --- a/plugins/code-review/SCHEMA.md +++ b/plugins/code-review/SCHEMA.md @@ -316,6 +316,12 @@ ignored at spawn time.

Spawned reviewer/verifier agents inherit the invoking SESSION's working directory, so on any worktree-based run "read the working tree" means a different checkout than the diff, and a clean report from there is indistinguishable from a real pass. Every dispatch stage (`derive-spawn-spec`, `derive-static-spec`, `verify-prepare`, `review-dismissed-prepare`) re-proves the root — it must exist, be a git worktree root, still be on `review_root_sha`, and contain every non-removed file in `diff_data.json` — and exits `3` when it cannot. The walker aborts on exit `3` regardless of the stage's `on_failure`, because those stages are `on_failure: continue` and every path a continue degrades to — the static reviewer table, "no verifier this run" — dispatches the same agents against the same wrong tree. A positional scope argument that is a git ref or revision range (e.g. `origin/main...HEAD`) is also rejected here rather than folded into a pathspec that matches nothing. After this stage, run `finalize-cache` to populate `/cache_config.json`. The walker uses these for token resolution downstream. **PR-head worktree (local PR review):** for `MODE=local` PR reviews (`scope_kind == "pr"`, not hygiene-only) resolve-scope isolates source reads so reviewer/verifier agents read the PR head, not the operator's working tree. The diff is computed from the fetched remote refs (`origin/...origin/`); reading the working tree is safe **only** when it already IS the PR head with a clean tree. Otherwise resolve-scope materializes a detached git worktree at the PR head SHA under `/pr_head_worktree` and records its absolute path in `review_root`/`worktree_path`; reviewer prompts and verifier inputs then read **source** under ``. **Fail-closed:** if isolation is required but cannot be established (PR head unresolvable, or `git worktree add` fails), resolve-scope returns non-zero and the run aborts (`on_failure: abort`) rather than silently review the wrong branch — the operator is told to check out the PR branch or fix the git error. `worktree_path` is empty (no isolation needed) for the already-at-head-and-clean case, staged/file/branch scope, hygiene-only, and GitHub mode (where the runner already checks out the head); `review_root` is still populated in all of those, from the invoking checkout. **Worktree lifecycle:** resolve-scope runs a startup GC (`_gc_stale_pr_head_worktrees`) that reclaims orphaned `cr-*/pr_head_worktree` checkouts from prior runs that aborted before teardown; `stage_30_footer` tears down the current run's worktree (validating the path equals the canonical `/pr_head_worktree` before the destructive removal). Because the walker can abort before the footer, the next run's startup GC is the backstop — a leaked worktree is never silently reused. Graph-aware reviewers run grep-only (`GRAPH_PROJECT=""`) whenever `worktree_path` is set, since the knowledge graph indexes the operator checkout, not the PR head. +- **stage_03_resolve_scope**: writes `/scope.json` with `diff_scope`, `base_ref`, `head_ref`, `review_branch`, `diff_tip`, `pr_number`, `path_filter`, `scope_kind`, `pr_auto_detected`, `head_sha`, `review_root`, `review_root_sha`, `worktree_path`. **Review root:** `review_root` is the absolute root of the checkout the diff was computed from — the PR-head worktree when one was created, otherwise the invoking checkout's `git rev-parse --show-toplevel` — and it is **always** populated; resolve-scope returns non-zero rather than emit an empty one.

A positional scope argument that is a git ref or revision range (e.g. `origin/main...HEAD`) is also rejected here rather than folded into a pathspec that matches nothing. After this stage, run `finalize-cache` to populate `/cache_config.json`. The walker uses these for token resolution downstream. **PR-head worktree (local PR review):** for `MODE=local` PR reviews (`scope_kind == "pr"`, not hygiene-only) resolve-scope isolates source reads so reviewer/verifier agents read the PR head, not the operator's working tree. The diff is computed from the fetched remote refs (`origin/...origin/`); reading the working tree is safe **only** when it already IS the PR head with a clean tree. Otherwise resolve-scope materializes a detached git worktree at the PR head SHA under `/pr_head_worktree` and records its absolute path in `review_root`/`worktree_path`; reviewer prompts and verifier inputs then read **source** under ``. **Fail-closed:** if isolation is required but cannot be established (PR head unresolvable, or `git worktree add` fails), resolve-scope returns non-zero and the run aborts (`on_failure: abort`) rather than silently review the wrong branch — the operator is told to check out the PR branch or fix the git error. `worktree_path` is empty (no isolation needed) for the already-at-head-and-clean case, staged/file/branch scope, hygiene-only, and GitHub mode (where the runner already checks out the head); `review_root` is still populated in all of those, from the invoking checkout. **Worktree lifecycle:** resolve-scope runs a startup GC (`_gc_stale_pr_head_worktrees`) that reclaims orphaned `cr-*/pr_head_worktree` checkouts from prior runs that aborted before teardown; `stage_30_footer` tears down the current run's worktree (validating the path equals the canonical `/pr_head_worktree` before the destructive removal). Because the walker can abort before the footer, the next run's startup GC is the backstop — a leaked worktree is never silently reused. Graph-aware reviewers run grep-only (`GRAPH_PROJECT=""`) whenever `worktree_path` is set, since the knowledge graph indexes the operator checkout, not the PR head. - **stage_07_auto_incremental**: runs **before** `stage_05_parse_diff` (its array position is between `stage_04_finalize_cache` and `stage_05_parse_diff`). This ordering matters: any `diff_scope` override must be applied to the cached `` token BEFORE parse-diff and extract-patches materialize `diff_data.json` and `patches_all.txt`, otherwise downstream stages see full-PR diff data alongside a narrowed token. The stage retains its `_07_` id as a stable label; execution order follows array position. Writes `/auto_incremental.json` with optional `diff_scope` (override) and `review_mode_line`. If `diff_scope` is non-null, update the cached `` token. Print `review_mode_line` (always) and, if `pr_auto_detected` was true in `scope.json`, print `"Auto-detected PR # for branch ."`. - **stage_08_fetch_intent**: the helper writes `intent_context.json` into `cr_dir` itself; its stdout is a small `{path, source}` summary that the walker discards. The run plan's `stdout` field is `None` here because redirecting stdout to `intent_context.json` would corrupt the file by overwriting the helper's structured payload with the summary. - **stage_09_detect_injection** (PLN-720): scores PR title/body/commits against the canonical 9-pattern catalogue and writes `/injection_report.json`. On severity ≥ Medium (score ≥ 30), rewrites `/intent_context.json` in place with `quarantine: true` and redacted fields. On severity ≥ High (score ≥ 70), also writes `/agent_injection-detector.json` containing a canonical `InjectionAttempt` finding — the `agent_*.json` naming makes `cmd_collect_findings` pick it up via the standard glob with no extra wiring. Always appends one JSONL entry to `.closedloop-ai/injection-log.jsonl` (90-day TTL, swept on read). `on_failure: continue` is intentional — a detector crash must never abort the pipeline. @@ -389,11 +390,11 @@ These notes annotate the run-plan stages with anything not obvious from the plan - **stage_12_hygiene**: writes `/hygiene.json` with hygiene findings. Triggers **Gate A** (hygiene-only exit) immediately after. - **stage_17_partition**: positioned in the run plan array after `stage_19_cache_check` so Gate B's `route` invocation runs first and supplies `--max-bha-agents`. The stage id retains its `_17_` prefix as a stable label (stage ids are not strict ordinals; execution order follows array position). Reads `partitions.json` afterward; entries shape `{id, files, total_loc, is_test_only}` with `files[].file` (NOT `path`), `files[].loc`, `files[].is_test`, optional `files[].line_range`. **PLN-774**: top-level keys also carry `partition_mode` (`"unified"` | `"partitioned"`), `partition_count`, `total_changed_loc`, and `unified_threshold_loc`. When total changed LOC ≤ `BHA_UNIFIED_THRESHOLD_LOC` (default 5000, settable via `.closedloop-ai/settings/code-review.json:bha_unified_threshold_loc`; `0` = always partition), the partitioner emits a single unified partition holding every file so cross-region invariants stay visible to one BHA reviewer's context. `cmd_verify_prepare` propagates `partition_mode` + `partition_count` into `verify_manifest.json` for the presenter footer. The `stats.verification.by_reviewer` block naturally labels BHA by partition via the filename-derived `reviewer` field (`agent_bha_p0.json` → `reviewer='bha_p0'`) — no extra split logic is needed; under unified mode only a single `bha_p0` bucket exists because there is only one partition. - **stage_19_cache_check**: writes `/cache_result.json` (stats), `/agent_cached_bha.json` (cached BHA findings, glob-compatible with `agent_*`), `/uncached_diff_data.json` (filtered diff_data for uncached files). Do NOT print the cache status here — it is printed in Gate A (hygiene exit) or Gate B (after route). -- **stage_19b_derive_spawn_spec** (PLN-725): runs `derive-spawn-spec`.

The fast-path branch from Gate B is honored (`fast_path: true` → single `fast` agent, bucket walk skipped). BHA descriptors are capped at `coverage_plan.budget.bha_partitions` (the post-arbitrate cap, which may be < the partitioner's output count); the excess partitions land in `skipped[]` with `reason: "budget_capped"`. A BLOCKING verify verdict (`budget.gated_by_verify: true`) drives **plan sanitization**: only `source: "core"` reviewers survive; every `rule` or `critic` entry is moved to `skipped[]` with `reason: "gated_by_verify"` (the canonical BLOCKING finding from stage_15c remains the operator-facing signal). Required-bucket skips with non-benign reasons (everything except `deferred_pln723`, `no_partitions`, `gated_by_verify`) generate coverage-gap findings appended to `/coverage_gaps.json` so finalize-result picks them up — the spec-driven dispatch never silently drops a required reviewer. `on_failure: continue` — a derive failure writes a sentinel spec with `arbitrate_status: "fallback"` (`fallback_reason` ∈ {`coverage_plan_missing_or_malformed`, `partitions_missing_or_malformed`}), which the stage_20 orchestrator interprets as "ignore the spec, use the static reviewer table fallback in the `code-review:spawn-reviewers` skill." Note: stage_19b depends only on `stage_16_arbitrate_budget`, NOT on `stage_17_partition`, so Gate B's fast-path branch (which skips stage_17) can still reach stage_20 with a fast descriptor. +- **stage_19b_derive_spawn_spec** (PLN-725): runs `derive-spawn-spec`.

Note: stage_19b depends only on `stage_16_arbitrate_budget`, NOT on `stage_17_partition`, so Gate B's fast-path branch (which skips stage_17) can still reach stage_20 with a fast descriptor. - **stage_20_spawn_reviewers**: agent_fleet stage. Invoke the `code-review:spawn-reviewers` skill. The skill reads `/spawn.json` (`spec` section) first and dispatches one Task per agent descriptor (using the `agent_id`, `reviewer`, `model`, and `patches_file` from the spec). If `spawn.json` is missing, its `spec` section is absent, or it marks `arbitrate_status: "fallback"`, the skill walks its static reviewer table fallback instead — a derive failure must never block review. In `MODE=github`, the walker must follow the skill's synchronous standard-flow branch: do not use `TaskOutput`, watcher files, sleep loops, polling loops, or turn-ending waits as replacements for synchronous reviewer completion. `stage_20` must complete every GitHub synchronous reviewer and retry, leaving no reviewer task still running, or fail before `stage_21_collect_findings`. - **stage_20b_verify_spawn** (PLN-725): runs `verify-spawn`. Reads `/spawn.json` (`spec` section) and globs `/agent_*.json`; for every descriptor with `bucket: "required"` that has no on-disk output, appends a coverage-gap finding to `/coverage_gaps.json` (reason `spawn_missing_required_agent`) and records the omission in `/spawn.json` (`verification` section). Missing best-effort descriptors are recorded for telemetry but emit no finding — best-effort omissions are budget-driven, not coverage gaps. No-ops cleanly when the spec is missing (`spec_missing`), marks fallback (`spec_fallback`), or contains no agents (`spec_empty`). `on_failure: continue` — a verification bug must never block review; worst case is missing telemetry, not a halted pipeline. Wired before `stage_21_collect_findings` so the gap findings land in `coverage_gaps.json` in time for `cmd_finalize_result` to merge them into the canonical envelope. - **stage_22_validate**: writes `/findings_validated.json` via `> /findings_validated.json` redirection. Validates finding scope and applies the out-of-hunk confidence gate. P2+ findings whose `line` falls outside the file's changed range survive when `confidence > out_of_hunk_confidence_floor` (default `0.80`, operator-tunable via `.closedloop-ai/settings/code-review.json:out_of_hunk_confidence_floor`, range `[0.0, 1.0]`) — this admits legitimate companion-change findings (e.g. a signature change in the diff window leaving stale sibling call sites just outside it) while still filtering low-confidence noise. Survivors get tagged `out_of_hunk_kept: true` so presenters can label them as companion-change without re-deriving hunk membership; the validate-stats block exposes `kept_out_of_hunk` and `discarded_out_of_hunk_low_confidence`. The comparison is strict `>`, so setting the floor to `1.0` is a kill switch (nothing can clear); setting it to `0.0` lets every out-of-hunk P2+ through (lean on the PLN-722 verifier downstream). Per-finding verification (stage_23) still applies on top, so noise that surfaces here gets a second-pass CONFIRMED/REJECTED verdict. -- **stage_22b_verify_prepare** (PLN-722): tier-selects findings for verification per the canonical table — BLOCKING/HIGH always; MEDIUM with confidence < 0.85 yes; MEDIUM with confidence ≥ 0.85 no; LOW (P3) no; `category: "Hygiene"` no; `source: "injection-detector"` no.

When `--cache-dir` is set, fresh verifier outputs from a prior run for the same `(finding_id, code_snippet_hash, model, prompt_hash)` tuple are pre-materialized at `agent_verifier_.json` and skipped from `to_verify[]` (logged under `cache_hits[]`). `on_failure: continue` is intentional — verify-prepare failure degrades to "no verifier this run", not a pipeline abort. +- **stage_22b_verify_prepare** (PLN-722): tier-selects findings for verification per the canonical table — BLOCKING/HIGH always; MEDIUM with confidence < 0.85 yes; MEDIUM with confidence ≥ 0.85 no; LOW (P3) no; `category: "Hygiene"` no; `source: "injection-detector"` no.

Invoke the `code-review:verify-findings` skill. Each spawned agent reads its `verifier_inputs/.json` (containing the finding + the `verifier_prompt_path` + the canonical `output_path`) and emits one verdict file at `/agent_verifier_.json`. `on_failure: continue` so a single agent crash never aborts review. In `MODE=github`, the walker must follow the skill's synchronous verifier branch: do not use `TaskOutput`, watcher files, sleep loops, polling loops, or turn-ending waits as replacements for synchronous verifier completion. `stage_23` must complete every GitHub synchronous verifier, leaving no verifier task still running, or fail before `stage_24a_verify_consolidate`. - **stage_24a_verify_consolidate** (PLN-722, extended in PLN-721): merges all `agent_verifier_*.json` outputs back into the validated set, applies sensitive-path escalation from `.closedloop-ai/settings/verification-gates.json` (rules: REJECTED on `sensitive_paths` + BLOCKING/HIGH → TENTATIVE with severity capped at HIGH; any finding on `tentative_on_paths` → TENTATIVE; any finding on `mandatory_human_review_paths` → TENTATIVE + `force_human_review: true`), routes JUSTIFIED-VALID verdicts to a new `justified[]` bucket and JUSTIFIED-INVALID verdicts back into `verified[]` (the audited justification was refuted; the original concern stands), and writes `/findings_verified.json` with the bucket-split shape `{verified[], rejected[], pending_verification[], justified[], force_human_review}`. `tentative_on_paths` lifts JUSTIFIED-VALID/INVALID to TENTATIVE on the same operator-policy contract as the other verdicts. When `--cache-dir` is set, fresh verifier outputs are written back to the `verifications/` namespace (30-day TTL) for re-use on subsequent runs. Missing fleet outputs degrade to `pending_verification[]`; `on_failure: continue`. - **stage_25_finalize_result** (PLN-722 + PLN-721): writes `/review_result.json` (the canonical envelope) BEFORE running schema validation. PLN-722: prefers `/findings_verified.json` (verify-consolidate output) when present and honors its `force_human_review` flag in the verdict computation; falls back to `findings_validated.json` (everything to `verified[]`) when verify-consolidate didn't run. PLN-721: pipes the consolidate `justified[]` bucket into the envelope, and loads operator-overridable thresholds from `.closedloop-ai/settings/verdict-thresholds.json` (defaults to `impact_cumulative=2`; absent/malformed → built-in default) so `_compute_canonical_verdict`'s cumulative Impact gate (FEA-1401 / PLN-726 OQ#6) can fire (≥ 2 BLOCKING/HIGH `ImpactAnalysis` findings in `verified[]` → NEEDS_ATTENTION). A non-zero exit signals reviewer-emitted category/field drift (e.g. a category not in the canonical enum) but does not block the pipeline — `on_failure: continue` lets `stage_28_verdict` read the structurally complete envelope.
