- Directly conducts finder jobs against diffs. Handles input parsing, context gathering, finder-job lifecycle, and result synthesis.

- These two premises are non-negotiable. They are forwarded through every finder-job prompt and govern every decision in this skill.

-

- 1. **Post-change state** — The working directory reflects the post-change state of the target ref. PR mode achieves this by checking out the PR head into a dedicated linked worktree (see Step 0). Non-PR modes (branch comparison, auto-detect) achieve this by verifying HEAD-match + clean-tree on the current working directory (also Step 0). Either way: read code freely from the working directory — the diff is the delta, the working directory is the result. Do not pretend the file system is read-only or stuck at base.

-

- 2. **No diff-only review** — A diff is a delta. The unit of review is the *system the diff produces*. Always trace dependencies, callers, callees, interfaces, configurations, and runtime context across files. If you cannot explain how the changed code behaves end-to-end against the surrounding system, you have not reviewed it.

-

- These premises must be reflected in the finder-job prompt — see Step 4. Review is static-only: do not run tests, builds, linters, formatters, migrations, or other project execution. The job lifecycle commands (`start`, `collect`, `status`, `results`, `clean`, and usage-summary) are allowed.

- When `project_context` contains a complete valid `[SCOPE_CONTRACT]`/`[/SCOPE_CONTRACT]` JSON envelope, apply it regardless of artifact filename or gate. It contains `outcome`, `verification_surface`, `constraints`, `boundaries`, `non_goals`, `stories`, and `scope_contract_sha256`; parse it before deriving requirements and preserve it unchanged through finder dispatch, direct candidate verification, cards, and the artifact. A delimiter appearing without a valid pair, or a request explicitly requiring a contract that omits or damages it, is `INCONCLUSIVE`; never fall back to ordinary review. A request with no contract retains ordinary behavior. `stories` are caller-provided approved requirement entries and workflow state is caller-owned.

- The contract and confirmed stories define authorization. Artifacts, codebase analogs, and derived expected-items may explain approved behavior; they cannot add acceptance criteria, revise boundaries/non-goals, or authorize collateral repairs. Tracing surrounding code is required evidence gathering, not permission to repair everything reached.

- Finders do not suppress candidates because of a non-goal. A candidate that may fall inside a declared non-goal is filed with that non-goal's exact `statement` (from the `non_goals` array) noted in its summary. For every candidate, the reviewer directly decides **scope before quality verdict**, including LOW cleanup and documentation findings; when the non-goal covers the defect, the reviewer records an OUT_OF_SCOPE note. OUT_OF_SCOPE reporting does not require searching for unrelated work. The reviewer checks both the symptom and a concrete proposed remedy.

- **Changed code is in scope by default.** Intent sources (the contract, stories, plan, issue, conversation, PR description) state requirements and explicit exclusions or accepted risks (for example, "we will not handle concurrency because it is rare"). A defect located in lines or code this change added or modified is IN_SCOPE with basis `changed_code`, whether or not a requirement mentions it. It leaves scope only when an explicit exclusion statement directly addresses that behavior or defect class. It is then OUT_OF_SCOPE with basis `non_goal`, and `scope_evidence.non_goal` holds that statement copied exactly. A requirement's silence never excludes. A decision about a different behavior never excludes. A defect in code the change did not touch is out of scope (`unrelated`) unless it prevents an approved requirement from working (IN_SCOPE, basis `requirement`) or this change worsens it (IN_SCOPE, basis `regression`). Its remedy is then the smallest local fix. An explicit exclusion stays an exclusion: the defect remains an OUT_OF_SCOPE note, not a repair demand. If the exclusion's stated premise contradicts the code, say so in the note. This does not block.

- **Remedy boundary.** A repair confined to code this change added or modified is authorized by default. Do not narrow the remedy to the reported site: when the same defect pattern exists in sibling changed code, list every sibling site in the finding's remedy. A regression this change introduced may authorize a minimal restoration or rollback of the prior behavior. It never authorizes enhancement of an excluded subsystem. If restoring an approved invariant needs new excluded behavior or a new capability outside the change, return UNKNOWN for a user scope decision. Use UNKNOWN for nothing else except a product requirement that is itself unclear: when a smaller remedy inside the change exists, judge IN_SCOPE with that remedy.

- **A scope reason never produces REFUTED.** REFUTED is a quality verdict only: the candidate is not a defect, and its audit entry cites the evidence that disproves it. For a code defect, that is the code fact (`file:line`). For a requirement-gap, it is the satisfying line, or the quoted intent text that shows the requirement was never stated. A plan, requirement, decision, or exclusion that excludes a defect is a scope reason, not evidence. A real defect judged out of scope stays CONFIRMED or PLAUSIBLE with scope OUT_OF_SCOPE, and appears in `findings.md` and the artifact as a visible nonblocking note.

- Each finding must carry reviewer-authored fields:

- `reference` names the contract key (`outcome`, `verification_surface`, `constraints`, `boundaries`, `non_goals`) or the confirmed story id the evidence rests on. IN_SCOPE requires basis `requirement`, `regression`, or `changed_code`, and evidence that the remedy fits the authorization. OUT_OF_SCOPE requires basis `non_goal` or `unrelated`. A `non_goal` finding copies one declared `non_goals` statement exactly into `scope_evidence.non_goal`, and that statement must directly address this defect's behavior or class. A paraphrase or partial quote degrades the finding to UNKNOWN. An `unrelated` finding concerns code this change did not touch. UNKNOWN requires basis `uncertain`. A basis its scope does not allow makes the whole artifact invalid for a caller that validates scope. Severity and confidence do not establish scope. Report all three scopes independently, with their evidence, for CONFIRMED and PLAUSIBLE findings alike. Leave repair, adjudication, completion, budget, and approval decisions to the caller.

- ## Do vs Delegate Decision Matrix

-

- | Action | YOU Do | DELEGATE |

- |--------|--------|----------|

- | Requirements 3-question gate | Yes | - |

- | Diff range determination & git | Yes | - |

- | Findings synthesis (rank/class verified findings) | Yes | - |

- | Individual candidate judgment inline (Phase 2) | Yes | - |

- | Individual finder review | NEVER | configured finder CLIs through direct jobs |

- | Code modification | NEVER | (forbidden entirely) |

- The reviewer directly verifies candidates in every mode, including reviews with a scope contract.

- ### Role Separation

- **Your role as orchestrator:**

- - Freeze the reviewable diff into cursor pages once (`diff-cursor.ts plan`), then start the direct finder job with `--ledger-root` (the job fans out the four angle finders, each walking 100% of the pages)

- - Judge each deduped candidate inline in Phase 2 (code and scope evidence → verdict + enrichment); enrich kept findings directly

- - Synthesize the kept findings into a ranked findings report (text only)

- - Rank the verified findings (no merge verdict — this review reports, it does not gate)

- **NOT your role:**

- - Modifying any source files

- - Running a general raw `git diff` command (the Step 3 candidate-scoped integrity exception and the Phase 2 candidate-file diff read are the only text-inspection carve-outs)

- ### Context Budget

- **Allowed in orchestrator context:**

- - `["git", "diff", range, "--numstat", "-z", "--find-renames"]` output

- - `["git", "diff", range, "--stat"]` output

- - `["git", "diff", range, "--name-only", "-z", "--no-renames"]` output

- - `["git", "diff", range, "--numstat", "-z", "--no-renames"]` output

- - `["git", "diff", range, "--name-status", "-z", "--find-renames"]` output

- - `--no-renames` name-only/numstat output is inventory/accounting only

- - `["git", "log", range, "--oneline"]` output

- - CLAUDE.md file content

- - chunk-reviewer results (candidate findings)

- - Phase 2 inline judgment output (reasoning, verdicts, enriched findings for every candidate)

- - Code reading via Read/Grep for Phase 2 inline candidate judgment

- - A candidate file's own diff (`git diff <range> -- <file>`), read in bounded parts in Phase 2 to establish which lines this change added or modified

- The orchestrator never loads the whole review diff as general raw-diff review input. In Phase 2 it may read one candidate file's own diff, in bounded parts, to establish which lines this change added or modified. The candidate-scoped diff inspection exception in Step 3 is for integrity judgment only. Its diff result is not forwarded to a finder prompt, candidate aggregation, or general orchestrator context. This exception does not permit project tests, builds, linters, formatters, migrations, or other project execution. The prescribed binary `git diff --no-ext-diff --binary ...` stdout byte stream flows directly to SHA-256 outside model context.

- Environment setup runs first — resolve the range and, in PR mode, check out the post-change code into the worktree **before** any code-reading step (intent acquisition, the derived-context sub-step, chunk-review). Every downstream step reads the working directory, so the working directory must already hold the post-change state.

-

- Determine range and setup for subsequent steps:

- | `pr <number or URL>` | Fetch and check out PR ref into the worktree (see below) | `origin/<baseRefName>...pr-<number>` |

- | `<base> <target>` | Verify HEAD is `<target>` via `git rev-parse --abbrev-ref HEAD`; verify clean tree via `git status --porcelain -uno`. Abort if mismatch or dirty. | `<base>...<target>` |

- | (none) | Detect default branch (`origin/main` or `origin/master`). Verify HEAD is the target branch via `git rev-parse --abbrev-ref HEAD`; verify clean tree via `git status --porcelain -uno`. Abort if mismatch or dirty. | `<default>...HEAD` |

- **Review base commit.** When the dispatch's `project_context` contains a line `Review base commit: <sha> — …`, use `<sha>...HEAD` as the range instead of the default branch. Verify clean tree as above, and verify `<sha>` like any other endpoint (below). With no such line, use the table.

- This skill assumes the orchestrator is already running inside a worktree dedicated to this review (the caller is responsible for creating the worktree). Therefore: **fetch the PR ref AND check it out**. The working directory must reflect the post-change state of the PR so that all subsequent code reading (Phase 2 verification, chunk-reviewer Step 2) sees the actual code under review.

-

- **PR ID extraction rule**: When the user supplies a URL (`https://github.com/<org>/<repo>/pull/<N>`), extract numeric `<N>` from the trailing path segment and substitute it for `<number>` *before* entering the bash block below. Substituting the URL itself makes `git fetch origin pull/<URL>/head` fail with an invalid refspec and `git checkout -B pr-<URL>` fail with an invalid branch name.

-

- # 0. Safety guards (Premise 1 enforcement) — abort BEFORE any state change

- # -uno: untracked files are preserved by checkout; only check tracked modifications

- if [ -n "$(git status --porcelain -uno)" ]; then

- echo "Error: working directory has uncommitted changes — refusing to checkout over the user's work" >&2

- exit 1

- fi

- # Distinguish primary repo from linked worktree.

- # In a linked worktree, --git-dir points inside .git/worktrees/<wt>,

- # while --git-common-dir points to the shared .git directory; they differ.

- # In a primary clone they are equal — refuse so we never checkout over the user's main work tree.

- if [ "$(git rev-parse --git-dir 2>/dev/null)" = "$(git rev-parse --git-common-dir 2>/dev/null)" ]; then

- echo "Error: refusing to run in primary repo — create a dedicated linked worktree first (Premise 1). Hint: 'git worktree add ../review-pr-<N> -b review/pr-<N>'" >&2

- exit 1

- fi

-

- # 1. Get base branch name (abort if gh fails or returns empty)

- BASE_REF=$(gh pr view <number> --json baseRefName --jq '.baseRefName')

- if [ -z "$BASE_REF" ]; then

- echo "Error: gh pr view returned empty baseRefName — aborting before any fetch" >&2

- exit 1

- fi

-

- # 2. Fetch base branch first, then PR ref last so FETCH_HEAD points to PR head

- # (rerun-safe — force-push on the PR is picked up on re-review)

- git fetch origin pull/<number>/head

-

- # 3. Reset local pr-<N> to the freshly fetched PR head (FETCH_HEAD) and check it out

- # so the working directory matches the PR state

- git checkout -B pr-<number> FETCH_HEAD

- If the working directory is dirty (uncommitted changes) or the caller is not in a worktree, abort and report — do not silently checkout over the user's work. The worktree premise is the safety net; without it, the safety net is gone.

- All range formats use **three-dot syntax** (`A...B`), which is equivalent to `git diff $(git merge-base A B)..B`. This shows only changes introduced by the target since the common ancestor — not changes on the base branch. This prevents false positives when `origin/main` has moved ahead after branching.

- All subsequent steps use `{range}` from this table. All subsequent commands that receive range or path values must use argv-safe arguments; if Bash is required, quote each dynamic value as a separate argument. After checkout, code reading via Read/Grep/Glob reflects the **post-change** state, which is the intended behavior — diff shows the delta, the working directory shows the result.

- Before constructing the review range, verify each raw base and target endpoint with the exact argv `["git", "rev-parse", "--verify", "--end-of-options", "<ref>^{commit}"]`. Abort and report on non-zero exit or empty stdout; never treat it as an empty diff. Construct `<baseSha>...<targetSha>` from verified commit IDs only and use it for every subsequent diff and log command. argv separation alone does not prevent Git option parsing; `--end-of-options` is required.

- **Untrusted path rendering contract:** Use the same strict escaped JSON/structured representation for every untrusted report path, including binary paths, derived artifact paths, pre-existing paths, and finding locations. Encode each path as a JSON string, escaping every JSON control character, including newline, plus backslash and double quote; additionally encode backtick, `<`, `>`, `&`, U+2028, and U+2029 as `\u` escapes. Preserve the encoded value only in an explicitly marked untrusted-data JSON array or structured JSON field. Use this representation whenever a path is surfaced; never raw Markdown/backtick prose, raw `file:line`, headings, fences, or shell commands. Decoded paths never enter prose, raw output templates, or command strings.

-

- ### Early Exit

-

- After the range is resolved and (PR mode) the checkout is done, before proceeding to Step 1:

-

- 1. Run `["git", "diff", range, "--stat"]` (using the range determined above)

- 2. If empty diff: report "No changes detected (between <base> and <target>)" and exit immediately without collecting this manifest

- 3. If the stat is non-empty, before deciding whether it is binary-only or reporting any binary-only result, collect a fresh `completeChangedFileManifest` with `["git", "diff", range, "--name-only", "-z", "--no-renames"]` and parse its stdout as NUL-delimited paths. Step 2 has not run yet; do not reference or reuse a Step 2 manifest. If the manifest/stat identifies a binary-only diff (if the diff is binary-only), enumerate every binary changed path under Out of Scope as an explicitly marked untrusted-data strict escaped JSON array of strings (one entry per path) under the Untrusted path rendering contract; do not render a raw path or `file:line` prose, state that no finder has run and no finder job is dispatched, and then exit

-

- Early Exit runs before intent acquisition on purpose — an empty diff exits immediately without manifest collection; after a non-empty stat, a fresh complete manifest is collected and parsed NUL-safely before binary-only determination/reporting, then binary paths are reported under Out of Scope before any finder runs and the review exits without dispatching a finder job.

-

- ## Step 1: Intent and Context Acquisition

-

- **Intent acquisition is non-negotiable.** Either intent is confirmed (from artifacts, interview, or both), or the user explicitly defers to a code-quality-only review. There is no third option — proceeding without intent and without explicit deferral is forbidden. Reviewing without intent produces wrong severities, missed scope creep, and false positives born from misunderstanding the author's goal.

- ### Acquisition order

- 1. **PR/branch artifacts** — PR title, description, labels, commit history. PR comments and review threads are not intent sources: the review is independent of them.

- 2. **Linked references (recursive)** — every link found in the artifacts above, followed transitively until the trail ends

- 3. **Codebase signals** — CLAUDE.md, README, ADRs, related history in changed paths

- 4. **User interview** — only for what the artifacts cannot reveal

- ### Acquire all reachable references

- PR descriptions and commits routinely link to richer context (issue trackers, design docs, chat threads). **Follow every link recursively** — a linked ticket may itself link to a doc which links to a discussion thread; keep following until the trail ends.

- Do not name specific tools. Use whatever fetch capability the environment provides for each link type. If a link cannot be fetched directly (no credential, no MCP for that platform, network unreachable), do not skip it — mark it for the user interview step.

- Sources to consult per input mode:

- | Input mode | Sources |

- |------------|---------|

- | PR | `gh pr view --json title,body,labels`, linked issues, `gh issue view <n>`, every external link found in the chain, commit messages on the PR branch |

- | Branch comparison | Commit messages, branch name conventions, any linked tickets discovered in commits, related issues |

- | Auto-detect | Recent commit messages on HEAD, any linked tickets found there |

- - **Explicit decision rules** — when an intent source (plan, spec, issue, PR description) states explicit decision rules (for example plan ADR items `### D-N: <title>` with a `Decision` field, or rule sentences in an issue), copy them verbatim into `{REQUIREMENTS}` as a `Decision rules:` block alongside the acceptance criteria. Each rule carries the full `Decision` field, plus `| Owns: … | Must NOT own: …` when the item has them. These are rules the frozen intent source already states, not new acceptance criteria, so copying them is not the addition that scope-contract mode forbids; never paraphrase and never author a rule the source does not state.

- ### User interview — only for what artifacts cannot reveal

- After exhausting fetchable sources, ask the user about:

- - **Intent** — what problem is this PR solving and why was this approach chosen

- - **Alternatives** — what was considered and rejected, and why

- - **Constraints** — deadlines, dependencies, compatibility commitments, hidden requirements

- - **Concerns** — known risks, untested paths, areas the author is uncertain about

- DO NOT interview the user about codebase facts (file locations, patterns, architecture, who calls what). Use Read/Grep/Glob and the explore agent for those — they are reachable from the working directory.

- ### Intent Block Gate (hard exit condition)

- Before exiting Step 1, the state must be one of:

- | **Intent confirmed** — author's goal, approach, and constraints are understood from artifacts and/or interview | Proceed to Step 2 |

- | **User explicit deferral** — user says "skip", "그냥 리뷰해줘", "없어", "code quality only", or unambiguous equivalent | Set {REQUIREMENTS} = "N/A — code-quality-only review (user deferred)" and proceed |

- | **Non-interactive dispatch (completion-gate)** — the dispatch prompt itself carries a supplied artifact destination alongside a 5-slot intent payload (`what_was_implemented`/`description`/`requirements`/`project_context`/`non_goals`) | Treat as **Intent confirmed (non-interactive, no user interview)** and proceed to Step 2. Acquisition steps 1-3 (PR/branch artifacts, linked references, codebase signals) still run — they backfill any slot whose value is the `(none provided)` marker (for `non_goals`, an empty array `[]`). Only step 4 (user interview) is replaced by the payload. The destination is opaque; do not infer workflow from its basename. |

- | **Neither** — artifacts thin and user not yet asked, OR user gave vague answers without explicit deferral | **BLOCK**. Do not proceed. Continue interview until one of the two states above is reached. |

-

- There is no "I tried hard enough, just review" path. The block IS the safety mechanism.

-

- A fresh code-reviewer agent has no ambient session to check for an active artifact path — the non-interactive discriminator above is prompt-borne: whether the dispatch prompt includes the supplied destination, not whether a session-scoped artifact happens to exist. The destination is opaque and may use any basename. When the signal is absent, the main-session interactive gate above (**Neither** → BLOCK) is unchanged.

-

- ### Vague answer refinement

-

- When the user gives a vague answer that is not an explicit deferral, refine ONCE with a specific follow-up:

-

- Include the deferral option in every follow-up so the user can opt out without already knowing the phrases "skip / 그냥 리뷰해줘 / 없어".

-

- | User says | Follow-up |

- |-----------|-----------|

- | "대충 있어" / "뭐 좀 있긴 한데" | "어디서 찾을 수 있나요? 링크나 문서 위치를 알려주세요. (답하기 어려우면 'skip'으로 코드 품질만 리뷰 가능)" |

- | "그냥 성능 개선이야" | "어떤 지표를 개선하려 했나요? (latency, throughput, memory 등 — 답하기 어려우면 'skip'으로 코드 품질만 리뷰 가능)" |

- | "여러 가지 고쳤어" | "가장 중요한 1-2개만 알려주세요. 나머지는 코드에서 식별하겠습니다. (답하기 어려우면 'skip'으로 코드 품질만 리뷰 가능)" |

-

- If refinement still yields a vague answer, surface the block explicitly to the user:

-

- > "의도를 명확히 잡기 어렵습니다. 둘 중 하나를 선택해주세요: (1) [구체적 질문]에 답하여 의도 확정, 또는 (2) 'skip / 코드 품질만 리뷰' 명시적 deferral. 둘 중 하나를 명시하기 전까지 리뷰는 시작하지 않습니다."

-

- This is not adversarial — it is refusing to silently produce a worse review.

-

- ### Question discipline

-

- | Situation | Method |

- |-----------|--------|

- | 2-4 structured choices (review scope, focus areas) | Propose alternatives, each with trade-offs |

- | Free-form / subjective (intent, alternatives, constraints, concerns) | Plain text question |

-

- **One question per message.** Never bundle. Wait for the answer before the next question.

-

- **Question quality** — every question must include either a specific anchor (a summary the user can correct) or a default action in parentheses (so progress is possible without an answer):

- | BAD | GOOD |

- |-----|------|

- | "요구사항이 있나요?" | "PR 본문과 연결된 이슈에서 [요약]을 추출했습니다. 보완할 부분이 있나요?" |

- | "어떤 부분을 볼까요?" | "23개 파일이 변경됐습니다. 집중할 영역이 있나요? (없으면 전체 리뷰)" |

- Include project context when interpolating the chunk-reviewer prompt template in Step 4. Describe what kind of software this is, who uses it, how it runs, and what depends on it — based on CLAUDE.md, README.md, and the artifacts gathered above.

-

- If available context is insufficient to characterize the project, ask the user once: "What kind of software is this? (e.g., personal CLI tool, internal team service, public-facing API, shared library, etc.)"

-

- ### Step 1 Exit Condition

-

- Proceed to Step 2 only when the Intent Block Gate state is **Intent confirmed** or **User explicit deferral**. Any other state → continue at Step 1.

-

- ### Bounded derived context (derived expected-items)

-

- **Scope-contract exception:** Keep the frozen requirements unchanged. Derive only supporting hypotheses about behavior already authorized by a contract key or confirmed story; label them as evidence and keep them separate from the authoritative requirements. An analog, general best practice, or review-derived expectation alone cannot become a requirement-gap or authorize new work. The unconditional rules below apply to other review modes.

-

- By this point `{REQUIREMENTS}` has settled — via interview, the deferral sentinel, or the completion-gate payload. This sub-step adds one more thing to it: **bounded derived context**, a codebase-grounded prediction of expected-items, kept distinct from intent *acquisition* above. "Intent acquisition is non-negotiable" (the Step 1 charter) means received, stated author intent is authoritative; this sub-step instead generates a hypothesis from the codebase's own "Codebase signals" (acquisition step 3) — it does not receive stated intent, it infers from what the codebase already does.

-

- Mirror the same reasoning shape the regression and cleanup finder angles use: name a thing the codebase already establishes, then check whether the change re-establishes it. Here: name a same-role analog already in the codebase, then check whether the change wires the new addition into it the same way. Derive an expected-item only through this named-necessity gate:

-

- | State | Condition | Action |

- |-------|-----------|--------|

- | Grounded + necessity-named | A citable codebase analog exists with a concrete `file:line`, AND a concrete runtime consequence of the item's absence can be named | **Keep** — emit the derived item |

- | Uncertain | Only one of the two holds, or either is fuzzy | **Drop** |

- | Neither | No citable analog, no nameable consequence | **never invent** |

-

- For each kept item, emit one bullet carrying four fields — self-labeling for provenance, so the downstream `requirement-gap` finding needs no new field to explain where it came from:

-

- - **Analog (`file:line`)** — the existing code whose role the missing item should mirror

- - **Why same role** — why the analog and the missing item play the same structural role

- - **Expected item absent here** — what the analog implies should exist in the changed code, and doesn't

- - **Runtime consequence of its absence** — what breaks, silently or loudly, if it stays missing

- Phrase the bullet itself like "Codebase analog at `file:line` implies `<wiring>`; absent here" — never "a requirement you stated is absent." The label must stay honest: a same-role analog implies wiring that is absent here, not a stated requirement that is absent.

- Fold kept items into `{REQUIREMENTS}` as a `Derived Expected Items` sub-block:

- - `{REQUIREMENTS}` already holds real content (caller/goal-lane requirements, or the completion-gate dispatch payload's `requirements` field) → **append** the sub-block after it; preserve what's there.

- - `{REQUIREMENTS}` holds the deferral sentinel `N/A — code-quality-only review (user deferred)` (set at the Intent Block Gate above) AND at least one item was derived → **replace** the sentinel with the sub-block, so coverage never sees a self-contradictory "N/A" plus derived items.

- - Zero items derived → leave `{REQUIREMENTS}` exactly as it was — no empty sub-block, no sentinel change.

- This sub-step is unconditional on intent-source: it runs the same way regardless of whether intent came from a live interview, a caller-supplied artifact, the completion-gate dispatch payload, or explicit code-quality-only deferral. It never gates on live-interview-only or on requirements already being present — it derives wherever the codebase grounds an item, and stays silent otherwise.

- When the deferral is an explicit *human* code-quality-only deferral (a person typed "skip" / "그냥 리뷰해줘" / "code quality only" at the Intent Block Gate) rather than the completion-gate's non-interactive payload, derived items are still surfaced — always-run holds even here — but their `Runtime consequence of its absence` text carries a short note such as "surfaced despite quality-only deferral," so the one mode where a person actively deferred scope stays framed honestly.

- Collect in parallel (using `{range}` from Step 0):

-

- 1. `["git", "diff", range, "--stat"]` (change overview; not the scale input)

- 2. `["git", "diff", range, "--name-only", "-z", "--no-renames"]` (file list)

- 3. `["git", "diff", range, "--numstat", "-z", "--no-renames"]` (per-file insertion/deletion counts)

- 4. `["git", "diff", range, "--name-status", "-z", "--find-renames"]` (rename/copy relation pass)

- 5. `["git", "diff", range, "--numstat", "-z", "--find-renames"]` (rename-aware insertion/deletion counts for scale)

- 6. `["git", "log", range, "--oneline"]` (commit history)

- 7. CLAUDE.md files: repo root + each changed directory's CLAUDE.md (if exists)

-

- Parse raw stdout as NUL-delimited records from all manifest commands. Never use newline, line, or word splitting, and never use shell command substitution. A name-only record is one path; a numstat record splits only its first two tab fields while preserving the remainder as the path. This preserves arbitrary Git pathnames, including newline, tab, quote, and backslash filenames. `--no-renames` avoids old/new pair ambiguity by emitting separate single-path records for each side of rename/copy changes. The relation pass is pairing only: parse its NUL-safe R/C old/new endpoint pair and normalize its R/C old/new endpoint pair; name-only/numstat outputs are membership/accounting and must not double-count endpoints or insertions.

-

- For NUL-separated `--numstat -z --find-renames` R/C output, associate one stats tuple with its R/C relation record, then consume its NUL-separated old/new endpoints as a pair. Do not interpret the endpoints as independent numstat records or add them twice.

- Keep the no-renames manifest for endpoint membership/path scope. Before scale, reconcile the rename-aware numstat records with the R/C relation map. For each R/C relation record, use its single rename-aware insertion/deletion tuple for scale; a pure rename contributes 0 insertions. Consume each no-renames endpoint exactly once for membership/accounting. The no-renames endpoint values remain membership/accounting only; never add the endpoint-level `--no-renames` values to scale.

- While parsing each NUL-delimited numstat record, treat an insertion or deletion field of `-` as numeric zero for `reviewableInsertionLines` arithmetic; preserve that path's binary marker separately. Normalize only finite numeric fields into the insertion/deletion sums: do not add `-`, `undefined`, or `NaN` (or any non-numeric value). This applies to mixed text/binary diffs when they are not binary-only. This is Step 2 accounting and must not be confused with the fresh-manifest binary-only Early Exit; the latter reports paths and exits before Step 2.

- Before partitioning, preserve the complete changed-file manifest from `--name-only` as `completeChangedFileManifest`. Build a separate `reviewableFileList` only after the integrity pass decides which paths remain reviewable; never use the complete manifest as finder scope. Then split that manifest into **reviewable source** and **derived artifacts**. A derived artifact is a file a build / codegen / lock / migration step mechanically (re)generates from other tracked source — you would never hand-edit it, so its diff is a tool's output, not an authored decision. This is ecosystem-agnostic; recognize it by the **category**, not a fixed filename list:

-

- - **Regenerable, not authored** — a command in the repo reproduces it (bundler, code generator, lockfile resolver, ORM schema-snapshot dumper).

- - **Carries a machine header** — `@generated`, `DO NOT EDIT`, Go's `Code generated by … DO NOT EDIT.`, and equivalents in any language.

- - **A dependency lockfile or a conventionally-generated path** — across ecosystems: `pnpm-lock.yaml` / `Cargo.lock` / `go.sum` / `gradle.lockfile` / `poetry.lock` / `composer.lock` / `Gemfile.lock`; build output under `dist/` · `build/` · `target/`; codegen such as `**/__generated__/**`, `*.pb.go`, `*_pb2.py`, `*.g.kt`; ORM migration snapshots like Drizzle's `**/migrations/meta/*_snapshot.json` · `_journal.json`.

-

- The filenames above are illustrations of the three categories, not a closed list — a Kotlin / Java / Go / Rust / Python project's generated files match the same categories under different names.

-

- **Initial classification:** candidate derived artifacts are not yet excluded until the integrity pass completes.

- **Partition per file, not per directory — keep the authored delta beside the generated state.** Exclude only the mechanically-generated file, never the hand-authored change it came from. The generated schema *snapshot/dump* is excluded; the authored migration or DDL beside it stays reviewable. The same split holds for any ORM in any language — drop the snapshot, review the migration: Drizzle's `meta/*.json` (excluded) vs its `NNNN_*.sql` and schema source (reviewable; the migration can carry destructive DDL); a Rails `schema.rb` dump vs its migration; a jOOQ/Diesel generated schema vs its migration.

- **Judgment carve-out — re-include when intent makes content meaningful.** Recognition is mechanical; exclude-vs-keep is gated on intent. A derived file returns to review when intent or an angle makes its bytes matter: a lockfile diff that intent frames as a dependency bump or supply-chain concern, or a generated file whose output shifted in a way the authored source change does not explain. When intent is silent and there is no such angle, exclude and note it — do not spend a finder job on generator output by default.

- To keep binary diffs out of model context, stream the complete candidate diff only to an out-of-band digest/byte-count sink; never load or print the full binary patch into model context. Expose bounded metadata: path, status, old/new object IDs or sizes, full-stream hash, and byte count; expose at most a fixed 64 KiB textual excerpt and an explicit truncation flag. Continue draining the producer stdout to EOF after the 64 KiB excerpt cap, hashing and counting every byte; finalize only after EOF and a complete hash/count. Any nonzero producer exit, partial/early stream, malformed metadata, or incomplete hash/count is `INCONCLUSIVE`; fail closed: do not exclude or silently drop the candidate, re-include it for review, and report the integrity failure. Never exclude a candidate solely from truncated evidence; require bounded integrity evidence or re-include it.

-

- Keep the two manifests as separate values. Never substitute one for the other. Before exclusion and before any path-filtered finder command, inspect each candidate derived file in the complete changed-file manifest by streaming its complete candidate-scoped diff only to the out-of-band sink above; inspect only the bounded integrity evidence against authored source/generator evidence:

-

- Before final integrity exclusion, run a bounded, selection-only relevance screen for each candidate against the review intent and every configured angle even when intent is silent. The screen uses candidate-scoped evidence only; it is not a full finder job or general aggregation and sends no diff bytes to either. Record a per-path decision and reason: if intent or any angle deems the exact path relevant, remove it from Out of Scope and re-include it in `reviewableFileList`, keeping it reviewable alongside its authored source or related rename endpoint (both enter the single job's scope). If no angle is relevant, leave the path in Out of Scope for final exclusion, including when intent is silent. After this screen, apply the final integrity exclusion.

-

- Execute this candidate-scoped diff through Bash. The preferred form is argv-safe direct process execution with the argument vector `["git", "--literal-pathspecs", "diff", "--binary", "--no-ext-diff", "--no-textconv", range, "--", candidatePath]`; if Bash must run the command, quote the diff range and candidate path as separate arguments:

-

- ```bash

- git --literal-pathspecs diff --binary --no-ext-diff --no-textconv "$range" -- "$candidatePath"

- ```

-

- Raw interpolation is forbidden. Git's `--` is only the revision/pathspec separator; it does not disable Git pathspec magic, external diff drivers, or textconv filters. `--literal-pathspecs` must be before `diff`; `--binary` is required, and `--no-ext-diff` and `--no-textconv` are required for this candidate integrity read. `--literal-pathspecs` treats the candidate path literally and is not shell escaping. These rules apply even when a changed filename contains spaces, shell metacharacters, command substitution, or newlines, including `:(exclude)*`.

- This candidate-scoped diff inspection exception is for integrity judgment only. Compare the changed bytes with authored source/generator evidence to decide whether the output is meaningful, stale, manually altered, or otherwise unexplained. Its diff result is not forwarded to a finder prompt, candidate aggregation, or general orchestrator context. Project tests, builds, linters, formatters, migrations, and other project execution remain forbidden. A `.d.ts` is excluded only with generated evidence; an authored `.d.ts` remains reviewable and contributes to `reviewableInsertionLines`. Authored migrations and DDL remain reviewable, including when a neighboring migration snapshot is derived. Authored `.d.ts`, migrations, and DDL remain reviewable without generated evidence.

- After this integrity pass and partition, finalize `reviewableFileList`; derive the scale units from the relation-reconciled reviewable subset for rename-aware insertion/deletion scale, while deriving `reviewableFileCount` as the finalized reviewable endpoint/path count (that is, count each path in `reviewableFileList` exactly once, including both endpoints of an R/C relation when both are reviewable). Derive `reviewableInsertionLines` from the `--find-renames` numstat insertion counts. R/C relation reconciliation is used for rename-aware insertion/deletion scale only; it does not collapse endpoint membership or double-count endpoints. Endpoint-level `--no-renames` values never feed scale. Derived artifacts do not satisfy the changed-file threshold.

- **Handling:** derived artifacts are excluded from the insertion-line scale count and are never assigned to a chunk or finder job — a 5,000-line `*_snapshot.json` must not inflate the scale decision or consume finder budget. They are **not** silently dropped: list them under Out of Scope in the report (synthesis item below) so the reader sees they changed and were not line-reviewed. Re-included outputs are reviewed as exact files instead.

- This is a valid zero-reviewable-files review. If `reviewableFileCount` is 0, do not dispatch a finder job, do not create an empty chunk or pathless diff, report all changed derived artifacts under Out of Scope, and explicitly report that this is not a single empty chunk. This branch applies only to a non-empty, non-binary-only diff after Step 2; empty-diff and binary-only Early Exit flows do not initialize these artifacts. If derived re-inclusion makes `reviewableFileCount` > 0, use the normal finder path instead.

-

- Before entering Phase 3, allocate a fresh cryptographically random, path-safe `invocationId`; before writing, verify that the invocation directory is contained within `$OMT_DIR/code-review`; atomically persist the frozen invocation manifest plus `candidates.json` with an empty `candidates` array (`"candidates": []`), using the normal invocation-manifest/`candidates.json` schemas and all configured angle coverage fields (one coverage record per configured angle, including unavailable angles); do not create or start a finder, job, chunk, attempt, or prompt, including an empty chunk or pathless diff.

-

- ### Scale

-

- Determine scale from the **reviewable subset** using the derived values — of the two line counts, only `X` (insertions), never `Y` (deletions), feeds this decision:

-

- These are the rename-aware, relation-reconciled scale values from Step 2: each R/C relation contributes its single insertion/deletion tuple to scale, pure renames contribute 0 insertions, while `reviewableFileCount` remains the finalized `reviewableFileList` endpoint/path count and endpoint-level `--no-renames` values never feed scale.

-

- `reviewableInsertionLines` and `reviewableFileCount` no longer branch review strategy and no longer produce a coverage notice: every non-empty reviewable set gets exactly four finders (one per angle) in one job, and every finder walks 100% of the diff.

- 1. For a valid scope contract, retain the complete frozen scope envelope in `{PROJECT_CONTEXT}` and the original requirements/non-goals when forwarding intent to finders. Read `scripts/chunk-reviewer-prompt.md` (the one finder template for all four angles) and interpolate the existing inputs: {WHAT_WAS_IMPLEMENTED}, {DESCRIPTION}, {REQUIREMENTS}, {PROJECT_CONTEXT}, {NON_GOAL}, {FILE_LIST}, and {COMMIT_HISTORY}. Before interpolation, path-bearing values must never be inserted as raw Markdown/prose: serialize `{FILE_LIST}` as a JSON array of path strings with the strict encoder from the Untrusted path rendering contract, and place it only in the template's untrusted-data JSON block. Any exact path echo in `{REQUIREMENTS}` uses the same escaped JSON string representation. Include each per-path relevance decision and reason in the existing `{REQUIREMENTS}` payload/finder handoff. These are the Step 3 relevance-screen results; then freeze the final `reviewableFileList`. Set {FILE_LIST} to the entire `reviewableFileList`. Pass re-included derived paths as exact path finder scope, keeping each re-included path reviewable alongside its authored source or related rename endpoint, including ordinary cross-directory rename endpoints. Never pass the complete changed-file manifest or derived-artifact Out of Scope list as finder scope.

- 2. The review receives one fresh cryptographically random, path-safe `invocationId`; never derive it from content or reuse it. Before the finder starts, durably persist a frozen invocation manifest containing the target, resolved launch context, the reviewable file list (the job's scope), and required job metadata. Recovery uses that ID and frozen values; conflicting state is rejected, not reused.

- **Resume dispatch.** When the dispatch carries `resume_invocation_id`, attach to that review instead of starting a new one; find its job dir from `external_stall` in the previous artifact at the supplied destination path (or the manifest under `$OMT_DIR/code-review/<invocationId>/`). If current HEAD differs from `reviewed_head_sha`, publish `INCONCLUSIVE` without `external_stall`, naming the mismatch. Otherwise run `job.ts resume-member --job <jobDir> --member <angle> --prompt "<note>" --retry-stalled` for each stalled member (it restores a ledger root lost to temp cleanup from `<jobDir>/ledger-backup`), run `collect` until terminal, and verify as usual. If `resume-member` refuses, a member ends with "plan changed since job start", or the ledger root is still missing, publish the same `INCONCLUSIVE` naming the cause, so the caller starts a fresh review.

- 3. The logical job key is `(invocationId, attempt)`. Same keys idempotently attach; different invocation IDs never share jobs or artifacts. Validate ownership and path containment on recovery, attaching rather than respawning. If `invocationId` is lost, safely start a new independent review rather than rediscovering by content. Pass commands, paths, and external values safely; use argv-safe direct process execution as the preferred form. If Bash is required, quote the range and every path explicitly; raw interpolation is forbidden.

- 4. Freeze the diff for the finders. Compute `ledgerRoot` = `<realpath(os.tmpdir())>/omt-code-review/<invocationId>` (the finder sandbox can write under the temp directory, not under `$OMT_DIR`), then run the planner once, passing the range and every reviewable path as separate argv values (argv-safe direct execution; if Bash is required, quote each value explicitly and never interpolate raw):

- Record `reviewed_head_sha` (the output of `git rev-parse HEAD` when you run `plan`) in the invocation manifest.

-

- `plan` freezes the diff of exactly the `reviewableFileList` into pages (default 24,000 UTF-8 bytes, max 32,000) and records the applicable guideline files for the cleanup finder: `CLAUDE.md`/`AGENTS.md` on the ancestor paths of the changed files, plus `.claude/rules` and `.codex/rules` in every ancestor directory of a changed file (a nested rule's `paths` globs are relative to the directory that owns that `.claude`/`.codex`; files are read from the reviewed head commit). Re-running it with the same inputs is a no-op. A different file list or range for an existing plan directory is refused. Each finder keeps its own ledger at `$ledgerRoot/ledgers/<angle>`; the worker creates it.

- 5. Start the one job with `job.ts start --ledger-root "$ledgerRoot" ...` before polling. `--ledger-root` is required: `start` refuses without it, so the `plan` step in item 4 must run first. `start` records the ledger root, the plan directory and the plan hash (`planSha`) in `job.json`. Exactly four finders run (correctness, regression, cleanup, requirement), and every finder walks 100% of the pages through the cursor. There is no chunking and no sampling. Drive the direct `job.ts` job (`start`, `collect`, `resume-member`, `status`, `results`) to terminal. Poll progress, interruption, or a running/ready job is never a retry. Run `job.ts --help` to see the full command roster grouped by who typically runs it — these tags are advisory only, since code-review has no write-guard enforcement.

-

- **Completion and resume policy.** A finder is complete only when its ledger is 100% acknowledged and finished (and, for cleanup, its checklist is finalized). A member whose turn ends below 100% is not `done`; it is `awaiting_resume`. Nothing resumes on its own: the conductor drives every resume. The conductor loop is:

- 1. Run `job.ts collect <jobDir>`. It re-reads status every 5 seconds and waits at most 20 seconds per call. It returns the manifest at once only when the job is `done`, or when it is `awaiting_resume` with no member running, retrying or queued. While another member still runs, it keeps polling. At the 20-second limit it returns `overallState: "running"` with member counts (including `awaiting_resume`).

- 2. For each `awaiting_resume`, `timed_out` or `error` member, run `job.ts resume-member --job <jobDir> --member <angle> --prompt "<note>"`. The member continues from its ledger, not from page one.

- 3. Run `collect` again. Repeat from step 1 until every member is `done` or `stalled`. Check `status --verbose` for each member's acked/total pages.

-

- The resume policy follows progress. Progress means the acknowledged pages, the checklist items or the checklist verdicts went up, or the ledger finished. Progress resets every counter. There is no fixed resume cap while progress continues. The stall sequence is:

- 1. After 3 consecutive resumes without progress (the initial turn counts), the next `resume-member` applies one remedy. It re-splits the issued page to half its size. If no page is issued, it spends one plain resume.

- 2. The next resume without progress marks the member `stalled` with a stated reason. A `stalled` member is never `done`.

- 3. A missing CLI, a non-retryable turn failure or a missing session id stalls the member at once. The reason reads "non-retryable failure: <detail>".

- A changed plan (`planSha` in `job.json` no longer matches `plan.json`) ends the member `error` or `stalled` with "plan changed since job start"; start a new job for the new plan.

- - To recover a `stalled` member whose cause you cleared, run `job.ts resume-member --job <jobDir> --member <angle> --prompt "<note>" --retry-stalled`. It always starts a fresh initial turn on the same ledger and resets the counters. On a member that is not `stalled`, the flag is ignored and the call runs as a plain resume.

- - The job deadline is for the coverage job as a whole. It slides only when a member acknowledges a page, adds a checklist item or sets its verdict or evidence (checklist item updates), or finishes its ledger. Heartbeats and resumes without progress do not extend it. It never passes 6 hours after job creation (or after the last external-cause `--retry-stalled`; see below). Past that wall cap, `collect` reports `stop_and_degrade` on every return, and `resume-member` refuses; `--retry-stalled` does not override it, except on a member stalled by an external cause, where it restarts the window. Workers are not killed, and candidates stay readable from the ledgers.

- - **External stall.** A member `stalled` with `stall_cause_kind` of `quota`, `auth` or `missing_cli` (`status.json` also carries `stall_detail` and, when known, `stall_reset_text`) needs something only the user can restore or wait out. `--retry-stalled` on such a member restarts the 6-hour window. A no-progress stall never restarts it. Publish an `INCONCLUSIVE` artifact through the normal publisher with `findings: []` and a top-level `external_stall` object: `{"invocation_id", "job_dir", "ledger_root", "plan_sha", "reviewed_head_sha", "cause_kind", "detail", "reset_text", "members": [{"angle", "state", "pages_acked", "pages_total"}]}`. Omit `reset_text` when unknown. Then end, and report the cause and reset text (display only; it has no timezone) to the caller. Never accept an incomplete walk, never run candidate verification below 100%, and never report a passed review below 100%. Any other stall (no progress) also publishes `INCONCLUSIVE` without `external_stall`.

- - Page notes are free prose for every angle; there are no per-angle templates. Only a blank note is refused. A note may record an open question as "check later: <what, where>" to revisit before `finish`. A finder re-reads all its notes in full with `diff-cursor.ts notes [--from <pageId>]`, paged under the output budget; `resume` prints the finder's position and the note count, and tells it to read the notes with `notes`. Doc and test pages may take a short note. After `finish`, the ledger refuses candidate and checklist writes.

- 6. Read each finder's candidates with `diff-cursor.ts --ledger "$ledgerRoot/ledgers/<angle>" export --out <file>` (the full JSON file: coverage, candidates, checklist, notes; `export --part N` gives budget-sized JSON parts) plus its final message, deduplicate candidates by normalized location and defect reason, union `found by` angles/evidence, and emit one coverage record per configured angle (including unavailable angles). Duplicates across angles are expected, because finders are not told to avoid other angles' areas; merge them here. Atomically persist `candidates.json` before `usage-summary`. Leave job cleanup to GC/orphan reaper; do not run `clean`.

- 7. Use the existing direct finder CLIs and prompt interpolation; do not dispatch chunk-reviewer subagents. Keep the review static-only and preserve all raw finder fields required by the aggregation contract.

- After all finder jobs reach terminal state, produce the final findings in two phases: direct per-candidate verification (Phase 2), and findings synthesis (Phase 3). The terminal deliverable is the **Phase 3 findings text** — no walkthrough, no diagrams, no HTML.

-

- The zero-reviewable exception applies when Step 3 yields no reviewable files: proceed directly to Phase 3. Phase 2: SKIP FOR ZERO-REVIEWABLE; do not create a finder job, empty chunk, pathless diff. Phase 3 must record all changed paths under Out of Scope and label this the zero-reviewable flow. The completion-gate artifact uses `"findings": []` and retains `"findings_report"`.

- Candidate verification starts only after the coverage gate passes. Run:

- `verify` must exit 0, which means all four ledgers are finished at 100% of the plan's pages (and the cleanup checklist is complete). On a non-zero exit, do not verify candidates: return to the Step 4 conductor loop (`resume-member`) for the members it names. If the gate cannot pass because a stall needs the user, stop and surface it. Never proceed on an incomplete walk.

- For the zero-reviewable flow, SKIP FOR ZERO-REVIEWABLE; do not create a finder job, empty chunk, pathless diff.

-

- Finders surface candidates; they do not judge them. For every review mode, verify each deduplicated candidate yourself, one at a time: read the code, trace the caller and runtime conditions, then record a verdict and its evidence. Do not spawn verifier subagents or assign numeric confidence scores. When you notice a different real defect while verifying, add it as a new candidate (file, line, summary, failure scenario, `found by: verifier`) and verify it in turn. You need not hunt for unrelated work.

-

- When a valid `[SCOPE_CONTRACT]` is supplied, use its original requirements/non-goals to judge both the symptom and proposed remedy before judging quality. Record `scope` and `scope_evidence` yourself, including OUT_OF_SCOPE and UNKNOWN. A missing/invalid scope decision makes the artifact INCONCLUSIVE. The contract adds scope evidence to the same direct verification procedure.

-

- **Inline judgment steps:**

-

- 1. **Dedup near-duplicates first** (same defect, same location, same reason → keep one, and carry onto it everything the duplicates contributed: the merged `found by` angles, the most concrete failure scenario, and any field only one of them supplied). Merging removes the repetition, never the substance. Deduplication reduces the judgment workload before it starts.

- 2. **MANDATORY READ: `references/verifier-prompt.md`** — read it before beginning judgment. Apply its verdict ladder (CONFIRMED / PLAUSIBLE / REFUTED), verification method, and enrichment output contract directly for each candidate.

-

- **Verifier interpolation safety** — When interpolating `references/verifier-prompt.md`, insert `{RANGE}` and `{CANDIDATE_FILE}` each as a complete strict JSON string literal, including its surrounding quotes, only at the unquoted value positions in that template's untrusted-data JSON block, encoded as the Untrusted path rendering contract defines. Parse the block first, then use the parsed `candidate.file` and parsed `execution.argv` values directly. Never echo decoded path and range values into Markdown/prose, the `File` field, a raw template, or a shell command. The location output is a structured JSON object (see LOCATION below).

-

- **No-safe-default candidates** — Before the mandatory **VERDICT** step, trace a no-safe-default candidate's execution model (concurrency, money, security, data destruction, external contract). "I did not trace it" is never a basis for PLAUSIBLE. When the execution model still cannot be established after tracing, record PLAUSIBLE, name the exact runtime fact that would settle it, and keep the finding with its priority and assessment in the card, `findings.md`, and the artifact `findings`. Never omit it, and never mark the review `INCONCLUSIVE` for this reason. Every candidate receives exactly one CONFIRMED / PLAUSIBLE / REFUTED verdict.

-

- 3. For each remaining candidate, in order:

-

- **REASONING** — read the code at the issue location (Read/Grep on the candidate file), trace the call chain from the entry point, and check the execution context (threading, dispatch model, runtime configuration). Apply the verdict ladder from `references/verifier-prompt.md`. Reason explicitly before issuing a verdict.

-

- **VERDICT** — exactly one of CONFIRMED / PLAUSIBLE / REFUTED (ladder in `references/verifier-prompt.md`).

-

- For **CONFIRMED** or **PLAUSIBLE** (kept findings), emit the full enrichment inline:

-

- ```

- VERDICT: <CONFIRMED | PLAUSIBLE>

- TITLE: <short finding title>

- LOCATION: {"file": <strict escaped JSON string of parsed candidate.file>, "line": <line>} — <section / function name>

- CURRENT CODE:

- <5-15 lines centered on the issue>

- WHAT'S WRONG: <the problem, grounded in the quoted line>

- FAILURE SCENARIO: <concrete inputs/state -> wrong output, crash, or lost effect; for a cleanup finding, the concrete cost>

- FIX: <concrete diff, or design direction if structural>

- BLAST RADIUS: <grep/reference evidence — what else references this, or "This location only">

- AC: <the candidate's acceptance criterion / inferred intent — omit this line entirely when it carries none>

- FOUND BY: <angle(s)>

- ```

-

- For **REFUTED**, emit a one-line note:

-

- ```

- VERDICT: REFUTED — <one line naming the evidence that proves it is not a defect>

- CODE EVIDENCE: {"file": <strict escaped JSON string>, "line": <line>} — <the quoted line/guard/invariant, or the satisfying line>

- INTENT EVIDENCE: <requirement-gap only, in place of CODE EVIDENCE: the quoted intent text that shows the requirement was never stated>

- ```

-

- A REFUTED entry with neither `CODE EVIDENCE` nor, for a requirement-gap, `INTENT EVIDENCE` is invalid. One whose reason is a plan, requirement, decision, or exclusion that excludes the defect is also invalid: that is a scope reason. Re-judge it as CONFIRMED or PLAUSIBLE and record that reason as its scope.

-

- 4. **Uncertainty** — when the mechanism is real but its trigger remains uncertain, record PLAUSIBLE and state the missing evidence. Preserve unresolved scope as UNKNOWN. If verification cannot be completed, report INCONCLUSIVE with the unverified candidates identified; never report an unverified review as clean.

- **Cap & batching:** judge at most **25 candidates per batch** inline. If more survive dedup, batch by file proximity, **correctness candidates first**, and state how many were deferred — never silently drop.

- This is a **report**. You surface verified findings, ranked by what matters most. You do NOT decide whether to merge and you do NOT decide whether to fix — that is the reader's call.

- For the zero-reviewable flow, record all changed paths under Out of Scope. Phase 3 writes `findings.md` under the same invocation directory and same invocation ID; the completion-gate "findings_report" points to that same invocation ID and `findings.md` path, with `"findings": []`.

- **Scope-contract synthesis:** Keep each finding's `scope` and `scope_evidence` unchanged in its full card and its artifact entry. Merge candidates only when their scope decision and authorized remedy agree, and keep all their evidence. Report OUT_OF_SCOPE (a nonblocking observation) and UNKNOWN (an unresolved scope decision) apart from IN_SCOPE findings, in `findings.md` and in the artifact. A scope-contract review keeps every verified finding, LOW included. Only an ordinary review applies the top-15 cap.

- 1. **Merge** verified findings that describe the same defect (same root cause, across chunks) — combine their evidence and note the corroborating angles. (Near-duplicates within a chunk were already deduped before verification.)

- 2. **Class** each finding by the defect's nature, not by the angle that found it: **correctness** (the change behaves wrong), **regression** (previously-working behavior the change breaks), **cleanup** (behaves correctly but is low quality), **requirement-gap** (an AC or stated requirement is absent — the behavior is missing, not wrong), or a short free-text class when none of these fits. `found by` records the angle(s) that surfaced it; a regression found by the correctness angle is still class regression.

- 3. **Impact** each finding: read its full card (failure scenario + blast radius) and assign the harm grade independently of confidence and priority. Impact is about the harm if the scenario occurs. Weigh occurrence rarity, patch size/touched lines, and maintenance exposure in priority, not in impact; the finding angle does not measure harm. A severe, irreparable harm remains severe even when occurrence is unknown or the cheapest remedy is expensive:

- - **HIGH** — realistic unacceptable harm such as data loss/corruption, money, auth/permissions failure, a working feature regression, required user-reaching behavior missing, user-facing crash, or unrecoverable damage.

- - **MEDIUM** — observable but recoverable harm, conditional wrong behavior, performance degradation, or a regression-detection gap.

- - **LOW** — subjective cosmetics, unclear benefit, or report-only quality observations whose harm is not user-impacting.

- Do not manufacture occurrence or exposure numbers. For occurrence, weigh competing requests for the same resource; batching and retries do not prove a globally concurrent user count. For maintenance exposure, weigh read/change frequency, not request count. Unknown exposure stays unknown.

- 4. **Assign priority** after the full card and impact are established. Priority is a response recommendation, not a severity score:

- - **HIGH** — a mandatory response is warranted because the realistic harm is unacceptable; expensive remediation does not downrate it. Seek the smallest mitigation that contains the harm.

- - **MEDIUM** — a bounded remedy has demonstrated net benefit after considering maintenance/regression burden, including cases such as a frequently edited duplicate with a small safe consolidation.

- - **LOW** — subjective cosmetics, unclear benefit, disproportionate remedy, or a retained report-only observation. Weigh unknown exposure and rare occurrence with the harm; neither alone makes a finding LOW.

- Record five nonblank assessment slots on every final finding: `unfixed_cost`, `exposure`, `remedy`, `added_cost`, and `rationale`. The conductor assigns priority and rationale after reviewing the complete card; direct verification supplies the grounded facts and assessment inputs; repair and completion remain caller decisions.

- 5. **Rank for display only** by **priority (HIGH, then MEDIUM, then LOW)**, then reviewer confidence (CONFIRMED before PLAUSIBLE). Impact remains a separate field and must not be used as a hidden priority score.

- 6. **Cap (ordinary reviews only)**: keep the most significant findings. If a review produced an unwieldy number, keep the top ~15 and state how many were dropped — never silently truncate.

- 7. **Pre-existing**: a candidate on an unchanged context line is tagged `[Pre-existing]` and listed under Out of Scope — unless the change worsens it (increases blast radius or frequency) or it prevents an approved requirement from working, in which case it stays in the main list.

- 8. **Derived artifacts**: files the Step 3 partition ultimately excluded are listed once under Out of Scope as `Excluded from review (derived artifacts):` followed by an explicitly marked untrusted-data JSON block whose structured `files` field is a JSON array of escaped strings produced by the same strict JSON encoder as the chunk prompt. Apply the Untrusted path rendering contract: never insert a raw path into Markdown prose, heading, or fence — the encoded array is the only path-bearing representation. This preserves derived artifacts as explicitly marked untrusted-data structured fields so the reader knows they were not line-reviewed, never silently omits them; any re-included file is removed from this list and reviewed as an exact file.

- All Phase 3 finding paths use the Untrusted path rendering contract in structured fields: use the structured LOCATION object with the same strict escaped JSON string in its `file` member and a separate `line`; never echo decoded paths into `findings.md` prose.

- 9. **Persist the cards**: write every kept finding's full verifier card (`references/verifier-prompt.md`, output contract), plus its class, impact, priority, and five-slot assessment, to `$OMT_DIR/code-review/<invocationId>/findings.md` — the same invocation directory as `candidates.json`. The artifact tuples are cut from these cards, so this file lets a caller re-adjudicate a finding after the review ends. After the cards, a `## Refuted` section lists each REFUTED candidate with its structured location, a one-line reason, and its evidence (the `CODE EVIDENCE` or `INTENT EVIDENCE` line). End the file with a `## Coverage` section: per finder, pages acknowledged / total pages, candidates proposed, and candidates retained after verification. Then add the cleanup checklist table with columns rule item, source `path:line`, verdict (`준수` / `위반` / `해당 없음`), and evidence, read from the cleanup ledger's `export --out <file>`. A `위반` row whose candidate did not survive verification states why it was dropped.

- | Fix cannot be expressed as simple diff | State design direction + "Concrete diff not possible — structural change required". |

- | Zero findings after verification | Report a clean review: "No findings survived verification." |

- | 50+ candidates requiring verification | Verify candidates yourself in batches (≤25), correctness candidates first. |

- ### Terminal Output

- This is a **report**. It does not gate. There is no Assessment / "Ready to merge" section, and there is no HTML — the deliverable is the Phase 3 findings as terminal text.

- The report carries no coverage-size notice: every finder reviewed 100% of the diff (the Coverage gate guarantees it), so the report states coverage as fact in the `findings.md` Coverage section instead.

- Every path-bearing terminal value uses the Untrusted path rendering contract: use a strict escaped JSON string in a structured field and never render decoded path text as Markdown or backtick prose.

- **Structured artifact publisher.** When the caller supplies an artifact destination, publish the original `CodeReviewArtifact` JSON through the generic bundled publisher with a safe quoted heredoc:

- {"status":"COMPLETE|INCONCLUSIVE","findings_report":"<optional findings.md path>","reviewer":"<reviewer id>","at":"<ISO timestamp>","findings":[{"class":"correctness|regression|cleanup|requirement-gap","verdict":"CONFIRMED|PLAUSIBLE","impact":"HIGH|MEDIUM|LOW","priority":"HIGH|MEDIUM|LOW","assessment":{"unfixed_cost":"<nonblank>","exposure":"<nonblank>","remedy":"<nonblank>","added_cost":"<nonblank>","rationale":"<nonblank>"},"ref":"<file:line>","scope":"IN_SCOPE|OUT_OF_SCOPE|UNKNOWN","scope_evidence":{"basis":"requirement|regression|changed_code|non_goal|unrelated|uncertain","reference":"<contract field or story id>","rationale":"<evidence>","non_goal":"<OUT_OF_SCOPE + non_goal only: one declared non_goals statement, copied exactly>"}}]}

- The publisher validates and atomically saves the original review JSON bytes, returning only the transport receipt `{"path":"<path>","sha256":"<hash>"}`. It has no caller, goal, session, aggregate, repair, or completion policy and never classifies destinations by filename. Valid or hashless `INCONCLUSIVE` diagnostics are published as supplied; the caller owns scope validation and all subsequent policy.

-

- `COMPLETE` is valid only when every retained finding has a non-blank `class`, the `verdict`

- and `impact` enums, plus `priority` and all five nonblank `assessment` slots. A review whose

- candidates were all verified is `COMPLETE`, including its `IN_SCOPE` + `PLAUSIBLE` findings; never

- invent certainty or a speculative repair. `INCONCLUSIVE` is for a review that could not be

- completed (unverified candidates, a missing or damaged scope contract). A no-safe-default finding

- whose execution model could not be established is a verified PLAUSIBLE finding, not a reason for

- `INCONCLUSIVE`. An `INCONCLUSIVE` artifact still lists its verified findings, classified like a

- `COMPLETE` one, and may omit only the `priority`/`assessment` fields when verification or scope is unresolved. If the

- `verdict` or `impact` enum is unavailable, do not invent it: keep the unresolved narrative in

- `findings_report` and omit that incomplete tuple from diagnostic `findings`. The publisher still receives the

- original JSON and returns only its `{path,sha256}` receipt; it does not assign priority, repair

- findings, or decide completion.

-

- The ordinary CodeReviewArtifact schema is fixed:

-

- ```json

- {"status":"COMPLETE|INCONCLUSIVE","scope_contract_sha256":"<hash>","findings_report":"<findings.md path>","reviewer":"<reviewer id>","at":"<ISO timestamp>","findings":[{"class":"correctness|regression|cleanup|requirement-gap","verdict":"CONFIRMED|PLAUSIBLE","impact":"HIGH|MEDIUM|LOW","priority":"HIGH|MEDIUM|LOW","assessment":{"unfixed_cost":"<nonblank>","exposure":"<nonblank>","remedy":"<nonblank>","added_cost":"<nonblank>","rationale":"<nonblank>"},"ref":"<file:line>","scope":"IN_SCOPE|OUT_OF_SCOPE|UNKNOWN","scope_evidence":{"basis":"requirement|regression|changed_code|non_goal|unrelated|uncertain","reference":"<contract field or story id>","rationale":"<evidence>","non_goal":"<OUT_OF_SCOPE + non_goal only: one declared non_goals statement, copied exactly>"}}]}

- ```

-

- This exact JSON is the input to `submit-review`; any caller may read or validate the resulting transport receipt according to its own policy.

-

- For a valid scope-contract artifact, additionally include the original `scope_contract_sha256` at top level and every finding's reviewer-authored `scope` and `scope_evidence` as defined above. These are required even for LOW findings and OUT_OF_SCOPE/UNKNOWN observations. The top-level hash is required only for `COMPLETE`; an `INCONCLUSIVE` artifact may lack it. Incomplete direct verification writes `status: "INCONCLUSIVE"` with the verified original hash; if no trustworthy hash exists, publish the hashless diagnostic as supplied. Never invent a hash or reconstruct one from mutable state to make it valid.

- A short deadline, seniority, “all bugs must be fixed,” or sunk cost never changes impact or

- priority by itself.

- Emit the ranked findings directly. Each finding carries its verdict, class, impact, final priority, and five assessment slots, named as in the artifact tuple above. Add the enrichment card from `references/verifier-prompt.md` (current code, what's wrong, failure scenario, fix, blast radius). Render every path as a structured LOCATION object under the Untrusted path rendering contract, with `line` separate. This findings text is also the handoff contract consumed by any caller that dispatches a code-reviewer agent that runs this skill — do not invent a different format.

- These files live in `references/` alongside this skill. Each is loaded only when the workflow reaches the step that needs it — do not preload all of them.
