From 086677ab59b219bccc009b9eb08dc67f3f613758 Mon Sep 17 00:00:00 2001 From: Scott Haug Date: Thu, 30 Jul 2026 16:00:37 -0700 Subject: [PATCH 1/7] feat(review-fix-loop): implement reviewer isolation and complete-review orchestration - Add `scripts/reviewer_orchestration.py`: fixed lens resolution, rejection of an incomplete/misbound review-code-change result (both a lens-completeness check via `evaluate_review_result` and a packet-evidence check via `evaluate_review_pair`), default fresh-subagent review-execution resolution with an explicit in-agent override and no automatic fallback, reviewer identity generation, before/after worktree mutation detection, checkpoint- shaped review-record construction that fails a cycle closed on any detected mutation, and deterministic finding normalization/selection. - Add `references/reviewer-orchestration.md`, implementing design's "Review execution" and "Reviewer write prevention" sections and workflow step 3. - Bundle the canonical review-suite contract into `references/review-suite/` (added review-fix-loop to `just sync-contracts` and to `review-suite/scripts/tests/test_bundled_contracts.py`'s `BUNDLING_SKILLS`), matching every other review-code-change consumer. - Update `SKILL.md` (frontmatter tool grants, description, a new "Run a complete review" section, and the non-goals list) and add `agents/ claude-code.md`/`agents/openai.yaml` adapters, mirroring review-code-change and implement-ticket's conventions. - Add `scripts/tests/test_reviewer_orchestration.py` (52 new tests). - Issue #98 (child of epic #95): reviewer isolation and complete-review orchestration is the next rollout step after the merged contract leaf (#96), and is required before either fix-cycle child (#99 local_commit, #100 update_pr) can run a trustworthy review.

Restart the complete +three-lens sequence — solution simplicity, correctness, then code simplicity — +after any such head-changing fix; a partial rerun (for example, only correctness +after a correctness fix, or only code simplicity and correctness after a +code-simplicity fix) cannot produce a valid `clean` aggregate. This child +defines no selective-reuse exception across different heads. + +### Consumer/impact evidence + +A `correctness` or `aggregate` result may record `consumer_impact_evidence`: one +entry per changed shared symbol or contract whose other call sites/consumers +were traversed, each naming the `changed_symbol`, its defining `location`, the +`consumer_search_evidence` inspected (one or more `location` + `detail` pairs +describing what was found), and a `disposition` of `all_consumers_consistent`, +`inconsistency_found`, or `no_other_consumers`. + +This makes a reviewer's consumer/impact traversal machine-checkable instead of +an unenforced expectation a reviewer can silently skip. The validator enforces +structure and non-emptiness; it does not determine which changed symbols require +an entry — that judgment belongs to the lens performing the traversal (a later +child consumes this schema to populate it). 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.

It does not define locking, isolated attempts, +worktree management, or publication — those belong to the sibling children this +document links to below.

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, refs, index, and + tracked/staged/unstaged/untracked/ignored worktree state immediately before + spawning the reviewer and immediately after it returns. Pass both snapshots + to `detect_worktree_mutation(before, after)`. +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. + +### 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, and one function each: + +- **Lenses**: `evaluate_review_result(result, expected_head, expected_base)` + validates the raw result alone. An empty return means it 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**: + `evaluate_review_pair(packet, result, expected_head, expected_base)` + additionally validates the raw evidence packet review-fix-loop actually handed + to the reviewer against its result. 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, which only `evaluate_review_pair` + inspects. Prefer this over `evaluate_review_result` whenever the packet is + still available — which it always is immediately after building it for the + reviewer. + +Treat any non-empty return from either function 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, when available, its packet) passes evaluation, call: + +```python +build_review_record( + sequence=, + result=, + expected_head=, + expected_base=, + independence=<"fresh_subagent" or "in_agent_override">, + reviewer_identity=, + mutation_attempts=, + packet=, +) +``` + +Passing `packet` runs `evaluate_review_pair`; omitting it falls back to +`evaluate_review_result` alone, which cannot catch a `clean` verdict paired with +a packet whose own required validation entry was actually `failed` or +`unavailable`. Always pass it when the packet is still available. + +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. This is what +makes finding-to-fix linkage and checkpoint replay reproducible given +byte-identical review evidence, instead of depending on incidental lens or +dict-insertion order. + +`select_next_finding(result["findings"])` returns the one finding a fix cycle +would target next: the first gating (`blocking` or `strong_recommendation`) +entry of that canonical order, or `None` when only `defer` findings remain. +Selecting a finding is not disposing or fixing it; a later child's Decide step +still verifies the selected finding's evidence against the candidate, confirms +it is within `change_contract.allowed_remediation_scope`, and only then accepts, +rejects, or defers it. + +## Related documents + +- [`design/review-fix-loop.md`](../../../design/review-fix-loop.md) — the + authoritative design this document implements a slice of. +- [`references/CONTRACT.md`](CONTRACT.md) — the invocation, checkpoint, and + terminal-result schemas' cross-field semantics `build_review_record`'s output + must satisfy. +- [`skills/review-code-change/references/orchestration-protocol.md`](../../review-code-change/references/orchestration-protocol.md) + — the lens sequencing and aggregation this document's "aggregate-review + subagent" invokes; this document does not redefine or duplicate it. diff --git a/skills/review-fix-loop/scripts/reviewer_orchestration.py b/skills/review-fix-loop/scripts/reviewer_orchestration.py new file mode 100644 index 0000000..6cb4ba1 --- /dev/null +++ b/skills/review-fix-loop/scripts/reviewer_orchestration.py @@ -0,0 +1,453 @@ +#!/usr/bin/env python3 +"""Reviewer isolation and complete-review orchestration for `review-fix-loop`. + +This module implements the design's "Review execution" and "Reviewer write +prevention" sections (`design/review-fix-loop.md`) and workflow step 3 +("Review"): resolving the fixed set of lenses a complete review must cover, +resolving which execution mode (`fresh_subagent` default or an explicit +`in_agent_override`) a given invocation actually gets, detecting an attempted +reviewer mutation from before/after worktree snapshots, building one +checkpoint-shaped `review_records` entry per review pass, and normalizing raw +findings into one deterministic order for later fix-cycle selection. + +It intentionally has no third-party dependencies, matching the convention +already used by `skills/review-fix-loop/scripts/validate.py` and by the +bundled `references/review-suite/validate.py` this module imports: a skill +folder is the unit of distribution, so its scripts must work standalone +wherever the skill is installed. + +This module does not run a subagent, spawn a process, or shell out to Git. +Actually creating a fresh reviewer context, restricting its tool surface, and +capturing real worktree state are host/runtime actions the executing agent +performs by following `references/reviewer-orchestration.md`; this module only +supplies the deterministic, testable decisions and data transformations that +sit around that action.

Sep 17 00:00:00 2001 From: Scott Haug Date: Thu, 30 Jul 2026 16:45:23 -0700 Subject: [PATCH 2/7] fix(review-fix-loop): reviewer-pair binding and refs mutation detection MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## Summary - `detect_worktree_mutation` now compares local `refs` (excluding `refs/remotes/*`) between before/after snapshots, not only `head_sha` and the tracked/staged/unstaged/untracked/ignored path lists — a reviewer that runs `git stash` or force-moves a branch without touching HEAD or any tracked path is now caught. - `evaluate_review_pair` no longer rejects a contract-legal `blocked` result that omits candidate identity already present in the packet (it stopped reusing the bundled `validate_pair`'s stricter packet/result identity check for that reason); it now additionally binds the *packet's own* candidate identity to the current cycle's expected head/base directly. - Extracted canonical `review_gate.evaluate_bound` (schema validation plus candidate/lens-execution binding, generalized to accept any verdict) in `review-suite/scripts/review_gate.py`, reused by `evaluate_aggregate` unchanged; `reviewer_orchestration.py` now delegates to it instead of a second, independently-maintained binding implementation. Added `review-fix-loop` to the `review_gate.py`/`test_review_gate.py` bundling loop (`just sync-contracts`, `GATE_BUNDLING_SKILLS`), matching `implement-ticket`/`babysit-pr`. - Updated `SKILL.md` and `references/reviewer-orchestration.md` to match: refs capture, preferring `evaluate_review_pair` (packet-bearing) over `evaluate_review_result`, and the shared `review_gate` dependency. ## Why - First review-code-change pass on #98 found: refs-only mutation went undetected (acceptance criterion 6 unproven for that class), a contract-legal blocked result was rejected on the packet-bearing path (SKILL.md's own recommended path), and the binding logic duplicated the canonical, drift-tested `review_gate` implementation used by two other consumers.

Jul 2026 17:22:48 -0700 Subject: [PATCH 3/7] fix(review-fix-loop): stop flagging ignored artifacts, fail closed on incomplete snapshots, collapse dual evaluators - `detect_worktree_mutation` no longer compares `ignored` worktree state (still required to be captured, per design, via `REQUIRED_SNAPSHOT_KEYS`, but never compared): authorized recorded validation commands legitimately create or change ignored build artifacts (`__pycache__/`, `.ruff_cache/`, `.venv/`), so comparing it made every review pass that ran validation falsely report a mutation and made `converged` permanently unreachable. - `detect_worktree_mutation` now raises `ValueError` when either snapshot is missing a required capture key (`head_sha`, `refs`, or any worktree category), instead of silently treating an uncaptured dimension as unchanged. - Collapsed the packet-less `evaluate_review_result(result, ...)` path into the single mandatory `evaluate_review_result(packet, result, ...)`: review-fix-loop's own checkpoint/terminal-result contract never persists a raw packet or raw result without the other, so the weaker path had no legitimate caller and could otherwise let a `clean` verdict with actually-failed packet validation slip through by omission. `build_review_record`'s `packet` parameter is now required accordingly. - Backfilled the two prior commits' SHAs into the changelog and removed a fabricated changelog entry from the prior fix-cycle commit. - Second review-code-change pass on #98 found: the `ignored`-comparison defect made `converged` unreachable in this repository's own worktree (every validation command run creates `__pycache__/`); a mutation-detection function silently passing on missing capture keys defeats the point of requiring the capture; and the packet-less evaluator path was unreachable by any real caller and duplicated the packet-plus-result path's logic.
