Given a supplied entry: + +- only `correctness` or `aggregate` results may include this evidence; +- every entry requires at least one concrete `consumer_search_evidence` item, + mirroring the existing "empty impact is valid only with concrete search + evidence" principle used elsewhere in this contract family — a disposition is + never accepted on the strength of an unevidenced claim; and +- `all_consumers_consistent` and `inconsistency_found` describe at least one + other consumer by definition, so each requires search evidence covering more + than the changed symbol's own location (two or more entries); + `no_other_consumers` requires only the one concrete search that found nothing + else. + +This validator deliberately cannot decide *whether* a given changed symbol +needed an entry at all, and an aggregate `clean` result that omits +`consumer_impact_evidence` entirely is schema-valid. That is not an oversight: +`scripts/validate.py` takes only a packet and a result as input and has no +repository checkout to search, so it cannot itself determine whether a changed +symbol has other call sites — the real baseline miss this evidence exists to +surface involved a sibling call site the diff never touched, which only live +repository access (available to the reviewing agent, not to this validator) can +find. Building that determination into the validator would be exactly the +independent correctness explorer and static call-graph tooling this contract +family's non-goals rule out. Completeness of a given traversal — did the lens +find every consumer that mattered — is judged by the lens performing the +traversal and by forward-testing its output against a fixture's expected result, +the same way this contract family already judges any other lens-specific finding +(a duplicated-policy or behavior-bug miss is likewise never something this +schema-and-structure validator can detect on its own). + +## Simplification proposal dispositions + +When an orchestrator asks correctness to assess a validated simplification +result, supply that result beside the unchanged review packet. Do not add review +conclusions to the packet itself. Correctness returns one +`proposal_dispositions` item for every supplied gating proposal: + +- `compatible` means the proposal preserves demonstrated correctness and remains + actionable; and +- `unsafe` means concrete correctness or repository evidence invalidates the + proposal even though the current candidate may already be correct. + +Each disposition identifies the source finding and lens and cites concrete +evidence. It does not describe a candidate defect and therefore does not change +the correctness verdict by itself. If correctness cannot assess a supplied +proposal trustworthily, return `blocked`. Only `correctness` and `aggregate` +results may contain proposal dispositions. + +## Candidate identity and base drift + +Bind every result to the packet's captured head and comparison base. Any edit, +rebase, conflict resolution, or update operation that changes the head +invalidates head-bound evidence and requires a new packet. + +When only the base advances, inspect the effective merge candidate. Retain prior +head-bound evidence only when all of these are true: + +- the effective diff is unchanged; +- the resulting tree is unchanged; +- no conflict exists; +- no relevant base code overlaps the candidate; and +- repository policy does not require a complete reset. + +Record the decision and reason in `base_drift`. Otherwise reset affected or all +evidence as repository policy and the changed candidate require. + +## Fixture use + +Each fixture keeps `expected.json` separate from `prompt.md` and `packet.json`. +Give a forward-testing reviewer only the prompt and raw packet. Do not expose +the expected outcome, implementation transcript, prior conclusions, or suspected +finding. diff --git a/skills/review-fix-loop/references/review-suite/review-packet.schema.json

The complete repository review +suite — `review-code-change`, which in turn sequences +`review-solution-simplicity`, `review-correctness`, and `review-code-simplicity` +— is the sole initial review mode for every cycle. Do not invoke an individual +lens directly, and do not accept an invocation field that tries to request a +narrower set; the invocation schema has none, and +`scripts/reviewer_orchestration.py`'s `resolve_review_lenses()` returns this +fixed set from the same constant the bundled review-suite contract uses to +enforce it (`REQUIRED_AGGREGATE_LENSES`), so no caller or test hand-copies the +three lens names and risks drifting from the contract that actually enforces +them. + +"Resolving" a review therefore means: confirm `review-code-change` and its three +lens skills are available (fail closed per its own `SKILL.md` if not), and +require every review pass's result to demonstrate it actually covered all three +— see "Rejecting an incomplete result" below. + +## Review execution + +The default execution mode is `fresh_subagent`. Every review pass: + +1. **Creates a new aggregate-review context.** In a runtime that supports + subagents (for example Claude Code's Agent/Task tool), spawn one new subagent + scoped to this pass only. Never reuse a subagent from a prior pass, and never + reuse the implementation/mutation context itself as the reviewer. +2. **Supplies only raw evidence.** Build the shared review-code-change packet + (goal, acceptance criteria, non-goals, preserved behaviors, sources, + candidate diff, worktree state, and exact focused/full validation evidence) + bound to the exact current head and comparison base. Withhold the + implementation transcript, the intended fix, prior conclusions, suspected + findings, and the expected result. +3. **Grants no mutation authority.** The reviewer subagent's tool surface must + exclude file-editing, commit, push, communication, merge, and + tracker-mutation tools. In Claude Code, restrict it to + `Read, Grep, Glob, Bash, Agent, Task, Skill` — the same tool set + `review-code-change` itself declares — never `Edit`, `Write`, `NotebookEdit`, + or any tool capable of a remote write. +4. **Discards the reviewer context after the result.** Do not carry a reviewer + subagent's working notes, intermediate reasoning, or session state into the + next pass or into the fix cycle that follows. + +`review-code-change` runs its own complete lens sequence +(`review-solution-simplicity`, `review-correctness`, `review-code-simplicity`) +inside that one aggregate-review subagent. Those nested lens invocations may +share the aggregate-review subagent's context — `review-fix-loop` does not spawn +a second subagent per lens itself, and this sharing does not weaken +completeness: `review-code-change`'s own aggregate `clean` verdict still +requires a fresh, current-head, `clean` execution from each of the three lenses +(enforced independently by the bundled contract's +`_check_aggregate_clean_lens_executions`, which `evaluate_review_result` below +reuses). Sharing a context changes *where* the lenses run, not whether each one +actually ran fresh against the exact candidate. + +### The explicit in-agent override + +`in_agent_override` runs the same complete aggregate review in the +implementation agent's own context instead of a fresh subagent. Use it only when +the invocation carries a non-empty `review_execution.override_authorization` +(already required by `validate_invocation`); there is no automatic fallback. + +- Call + `resolve_review_execution_mode(mode, override_authorization=..., host_supports_fresh_subagent=...)` + to resolve what this specific host and invocation actually grant. An explicit + override is honored regardless of whether the host could have run + `fresh_subagent` — the override does not require the fresh path to be + unavailable first. +- When `mode` is `fresh_subagent` and the host cannot spawn an isolated context, + `resolve_review_execution_mode` returns + `blocked_reason: "missing_capability"`. Return `blocked/missing_capability`; + never silently run in-agent instead. +- Record the resolved `independence` (`fresh_subagent` or `in_agent_override`) + in every `review_records` entry's `review_independence` field — this is what + makes "in-agent execution occurs only when explicitly requested and is + recorded in the result" true in the actual checkpoint/terminal-result + documents, not just in this document's prose. + +## Reviewer write prevention + +"Read-only" is a capability boundary, not merely prompt language. Apply every +tier the runtime supports, strongest first: + +1. **Immutable snapshot or deny-write filesystem boundary**, when the runtime + can provide one. +2. **A restricted reviewer tool surface** without edit, patch, file-write, + commit, push, or remote-write operations (see "Review execution" step 3 + above). +3. **Read-only inspection commands only** inside the reviewer context — + validation and diagnostic commands the invocation already recorded, never an + ad hoc write. +4. **Before/after state capture**: snapshot `head_sha`, local `refs` (for + example via `git for-each-ref`), and tracked/staged/unstaged/untracked/ + ignored worktree state immediately before spawning the reviewer and + immediately after it returns — every key `REQUIRED_SNAPSHOT_KEYS` names. Pass + both snapshots to `detect_worktree_mutation(before, after)`, which raises + `ValueError` if either snapshot is missing a required key (fails closed + rather than silently treating an uncaptured dimension as unchanged) and + otherwise compares `head_sha`, `refs`, and tracked/staged/unstaged/untracked + paths — a reviewer that runs `git stash` or force-moves a branch without + touching `HEAD` or any tracked path is still caught. `refs/remotes/*` entries + are excluded from the comparison: an unattributed remote-tracking-ref advance + is the ordinary `remote_advanced` publication-race contract (issue #97/#100's + scope), not reviewer misconduct. `ignored` is captured (required above) but + deliberately not compared: authorized recorded validation commands + legitimately create or change ignored build artifacts (`__pycache__/`, + `.ruff_cache/`, `.venv/`), so comparing it would make every review pass that + runs validation falsely report a mutation — this mirrors the + invocation-cleanliness contract's own rule that ignored files "do not + represent an uncommitted change and are not part of what 'clean' means here." +5. **Tool-trace inspection**, when the runtime exposes one, for an attempted + mutation that a capability boundary already blocked. + +Certification requires enforced write isolation; before/after verification alone +is not sufficient by itself — it is tier 4 of five, not a replacement for tiers +1–3 where the runtime supports them. + +An attempted prohibited mutation invalidates the review even when the runtime +blocked it. Feed every mutation description `detect_worktree_mutation` returns +(plus any tool-trace evidence) into `build_review_record`'s `mutation_attempts`. +A non-empty `mutation_attempts` always sets `write_isolation: "violated"`, +regardless of the aggregate verdict, and `scripts/validate.py`'s +`_check_converged_requires_clean_evidence` already rejects `converged` for *any* +`review_records` entry with a non-empty `mutation_attempts` — not only the +final-head-bound one. An unattributed remote-ref advance by itself is not proof +of reviewer misconduct; that is the ordinary `remote_advanced` publication-race +contract (issue #97/#100's scope), not a reviewer-integrity failure. + +**Stop immediately on a mutation attributable to this pass.** Design assigns +that judgment to "the phase that observed it" — this phase, the moment +`detect_worktree_mutation` (or tool-trace evidence) returns non-empty for a pass +this cycle just ran. Do not keep iterating on that pass's findings, and do not +wait for a later phase to notice the tainted `review_records` entry indirectly. +Stop the invocation and return `blocked/reviewer_integrity_failure` immediately, +preserving the unexpected worktree/ref state for operator inspection rather than +resetting or repairing it. The `mutation_attempts`/`write_isolation: "violated"` +chain into `_check_converged_requires_clean_evidence` is a backstop that keeps a +stale checkpoint from ever certifying `converged` later — it is not a substitute +for this immediate stop. + +### The reviewer briefing + +Call +`build_reviewer_briefing(independence=..., head_sha=..., comparison_base_sha=...)` +and prepend its return value to the raw evidence handed to the reviewer context, +before the review-code-change invocation itself. It states the exact execution +context, the exact candidate, and the literal prohibitions +(`REVIEWER_PROHIBITIONS`): report findings only; never stage, commit, amend, +rebase, or push any ref; never run a tool or command that writes to the working +tree, index, or any ref; never resolve conflicts, run formatters or codemods, or +apply any proposed fix, including one the reviewer itself proposes. This is the +acceptance criterion "Reviewer instructions explicitly prohibit worktree +mutation and implementation" made literal: the same wording travels with every +review pass instead of living only in this document. + +## Rejecting an incomplete result + +The acceptance criterion "Reviewer output is rejected if required lenses or +evidence are incomplete" has two distinct halves, both enforced by the single +`evaluate_review_result(packet, result, expected_head, expected_base)`: + +- **Lenses**: an empty return means `result` is schema-valid, cross-field + consistent, and bound to the exact head and comparison base this cycle + captured — including every `lens_executions` entry, not only the result's own + `candidate`. + - A `clean` verdict must demonstrate a fresh, current-head, `clean` execution + for all three required lenses; a result missing one, reusing a stale head, + or reusing an old base is rejected, not silently treated as complete. + - A `changes_required` verdict is not required to carry all three lens + executions: the orchestration protocol stops at the first gating finding, so + a partial `lens_executions` list there is expected and valid. + - A `blocked` verdict may omit candidate identity entirely when the caller + could not establish it; this is not treated as a stale-candidate mismatch. +- **Evidence**: the function also validates `packet` — the raw evidence packet + review-fix-loop actually handed to the reviewer — against `result` and against + `expected_head`/`expected_base` directly. A single-document check on the + result alone cannot see this: the shared review-suite contract's "validation + must back a clean verdict" rule (`_check_clean_requires_passing_validation`) + needs the packet's own `validation` array. + +`packet` is required, not optional: review-fix-loop's own checkpoint/ +terminal-result contract (from #96) never persists a raw packet or raw result on +its own, so no caller can legitimately hold one without the other, and a +packet-less evaluation could let a `clean` verdict with actually-failed packet +validation slip through undetected. + +Treat any non-empty return as a failed review pass: do not build a +`review_records` entry from it. `build_review_record` enforces this directly — +it raises `ReviewIntegrityError` instead of returning a partially trusted +record. + +## Building the review record + +Once a raw result and its packet pass evaluation, call: + +```python +build_review_record( + sequence=, + packet=, + result=, + expected_head=, + expected_base=, + independence=<"fresh_subagent" or "in_agent_override">, + reviewer_identity=, + mutation_attempts=, +) +``` + +The returned dict matches `checkpoint.schema.json`'s `review_records` item +exactly — append it to the checkpoint's `review_records` array (and, at return +time, the terminal result's own `review_records`). It leaves +`finding_dispositions` empty: disposing a finding as `accepted`, `rejected`, or +`deferred` is workflow step 4 ("Decide"), which this document and its script do +not implement. Populate that field only once a later child (or caller) actually +runs Decide for this exact head/base pair. + +## Normalizing findings for deterministic selection + +`review-code-change` does not guarantee any particular ordering of findings +across lenses or review passes. Call `normalize_findings(result["findings"])` to +get one deterministic order — sorted by severity (`blocking` before +`strong_recommendation` before `defer`), then lens, then stable finding `id` — +regardless of the input order the raw result happened to produce.
