# Review autonomy: live behavioral evaluation

## Review-state and output consistency

Rejection reuse now depends on whether the evidence supporting that rejection remains current, including relevant source changes. The template has one shared rule for rendering retained items and counts; it no longer counts rejected raw residuals or illustrates an unsupported deferred question. The planner keeps its existing decision-menu predicate and delegates resume behavior to document review.

Bounded fresh-session checks used pre-change `6cf05fc0c78cfad9e97f8832a3d5d597788df22e` and the edited working tree. Pre-change Fable low counted two rejected residuals; post-change Fable low and Astra low both counted zero and rendered only the retained support commitment question. In the evidence-freshness check, pre-change Fable already reassessed a demonstrated duplicate-billing defect after source changes and suppressed an unchanged naming preference, despite noting the conflicting literal rule. Both post hosts preserved those outcomes and denied that reassessment grants permission to reverse a user commitment. This establishes a rendering correction and reconciliation non-regression, not full-workflow coverage. Fable still narrates omitted items; no further tuning was attempted.

Explicit wrappers requested `claude-fable-5-1` low and `gpt-6-astra` low. Artifacts: `/var/folders/yr/rc1_m71d72zcl3zxwsdd75400000gn/T/ce-review-state-SbAlQ9`. The catalog's two new scenarios use durable pre-change ref `153e605e1622154a0d7da095fceed13edcb68bf7`, which was not the measured pre arm. An independent reader found no lost authority or presentation contract. Validation: 4,022 tests passed in 74.23 seconds; release and strict plugin validation passed.

## FYI template and caller-guide consistency

The interactive document-review template still illustrated a filename preference and unsupported monitoring thresholds as FYIs. Its FYI block now inherits synthesis admission and illustrates verified practical benefits. The two caller-guide descriptions that still promised an apply/file/accept/stop menu now describe the existing outcome-based gate: resolve justified work, stop for essential evidence or a user-only choice, and record other worthwhile concerns. No runtime synthesis or caller gate changed.

A bounded presentation scenario supplied those two noisy candidates and one verified fixture-setup benefit. Pre-change Fable low at `6d4a5b421822811a38950d3f71fd0bacd23209ef` already retained only the useful FYI. Current-tree Fable low and Astra low also retained exactly that one observation, with no edits or delegation. Fable narrated rejected candidates outside the FYI section in both arms; Astra returned only the requested section and count. This is template consistency and non-regression evidence, not proof of an additional reduction or generalization: the useful candidate shares the template's illustrative measurements. Explicit wrappers requested `claude-fable-5-1` low and `gpt-6-astra` low. Artifacts: `/var/folders/yr/rc1_m71d72zcl3zxwsdd75400000gn/T/ce-fyi-template-oEsJv0/{pre,post}`. The new catalog row `ce-doc-review/fyi-template-admission` uses the durable pre-change template at `153e605e1622154a0d7da095fceed13edcb68bf7`; that ref was not the measured pre arm.

An independent reader found no contract expansion. The existing synthesis condition now decides admission in the template; replacing the two examples removed no required gate. Validation: 4,022 tests passed in 74.82 seconds; focused rendering/contracts passed 167 tests; release and strict plugin validation passed.

## Settled code-review preferences: follow-up correction

PR review identified an exception that still reinserted preference-only feedback against a settled decision into the primary report. The synthesis policy now discards those candidates before the helper rerun. Evidence of real defects retains normal severity, and local apply still cannot reverse a settled decision without authority. The incoming `settled_conflict` field and helper compatibility remain; the marker no longer forces a finding into the report. The prior retention rule was explicitly pinned by contract tests, which were updated with the policy. The safety boundary they also protected remains in the apply condition.

A bounded routing scenario supplied two completed candidates: a confidence-suppressed preference for a class hierarchy explicitly rejected by the plan, and a verified missing ownership check whose fix preserves the selected function-based design. Fresh CLI sessions loaded extracted skill files. Explicit wrappers requested Claude `claude-fable-5-1` with low effort and Codex `gpt-6-astra` with low reasoning; Codex's stderr confirms the latter selection.

| Arm | Preference candidate | Ownership defect | Edit authority |
|---|---|---|---|
| Pre-change `9c9ec7d6d0644c4dcd0fa8c15bd0b556886168e4`, Fable low | Advisory/human; explicitly reinserted into primary output | Actionable | No local apply |
| Current working-tree skill, Fable low | Discarded, excluded from helper rerun and residual risks | Actionable, downstream resolver | No local apply |
| Current working-tree skill, Astra low | Discarded | Actionable, downstream resolver | No local apply |

These are routing checks, not full-review or mutation evidence. The outputs were read candidate by candidate; matching keywords alone would not distinguish an inverted answer. Fable still added verification narration beyond the requested routing answer. No additional tuning was attempted for that behavior.

The durable catalog row is `ce-code-review/settled-preference-admission`. It uses main-reachable `153e605e1622154a0d7da095fceed13edcb68bf7`, whose contract also retained settled preferences; the measured pre arm above used the exact pre-fix PR head and is not relabeled as a run against that catalog ref. Artifacts: `/var/folders/yr/rc1_m71d72zcl3zxwsdd75400000gn/T/ce-settled-review-lM9eGq/{pre,post}`. An independent reader confirmed the revised condition preserves genuine defects and settled-choice authority.

Validation for this correction: `bun run test` passed all 4,022 tests in 75.94 seconds after updating the old settlement-retention assertions; the first run caught that stale contract test. The focused three-file run passed 177 tests. Release metadata and strict plugin validation passed.

## Current ce-doc-review calibration

The default review now applies full-confidence corrections needed to implement a concrete decision already made in the document, provided a local reviewer supports the finding and no explicit edit restriction forbids it. Mechanical versus meaning-changing classification no longer makes every necessary correction an approval request. Broader improvements still need authority, peer-only findings retain R18, and unresolved user commitments remain protected.

The admission rule covers incompatible instructions and demonstrated consequences from following the whole document and its references. The feasibility reviewer no longer emits a finding merely because a path, performance target, or procedure is not enumerated. Severity follows the consequence, and the omission definition excludes details an implementer can already derive. No extra validator or review round was added.

Fresh CLI checks used `claude-fable-5-1` at low effort and `gpt-6-astra` at low reasoning. Observed parent model identities and explicit effort wrappers are retained with the artifacts. The callable workflow copies in each larger fixture were synchronized to the source snapshot tested by that run; the final ownership reassessment includes the later ownership restatement.

| Scenario | Fable 5.1 low | Astra low |
|---|---|---|
| Default review, broken CSV verification | Corrected only U2, no approval request | Corrected only U2, no approval request; repeated existing retention decision |
| Explicit report-only review | No edits; useful correction returned | No edits; useful correction returned; repeated existing retention decision |
| Broad privacy goal with deferred expiry policy | Rejected the expiry proposal; no edits or questions | Rejected the expiry proposal; no edits or questions |
| Fresh live reviewer generation | Corrected only reversed loader arguments; no pending findings | Corrected only reversed loader arguments; no pending findings |
| Larger completed-review synthesis, before final ownership restatement | Five applied groups, three proposals, eight decisions; excessive retained noise | Two applied groups, no proposals or decisions |
| Focused report-only reassessment with final ownership rule | Two decisions, five proposals, no edits | Zero decisions, four proposals, no edits or FYIs |

The final ownership block requires a specific unanswered user question before classifying a finding as a decision. It recomputes ownership from the document and evidence instead of carrying forward earlier reviewer labels. The completed larger Fable run motivated this restatement: its eight decisions described technical remedies without identifying what only the user could settle. A focused report-only reassessment of that actual output tests routing separately from edit permission. Fable reduced decision items from eight to two (75%) and actionable items from eleven to seven (36%). The independent grader confirmed no edits and the rejection of several unsupported concerns. Both remaining decisions still offer weakening settled goals as an alternative to required technical work; some FYI noise and a questionable fallback proposal also remain. Astra returned four proposed verification corrections, no decisions and no FYIs, while preserving the document. Both report-only outputs were byte-checked against the input plan. This is bounded routing improvement, not a clean end-to-end result or proof that the restatement alone caused every dropped finding.

The independent grader verified the first eight cells' document diffs, preserved production files and product choices, and actual reviewer completion for the live cases. Fable still explains rejected claims more than necessary. These are targeted behavioral results, not a guarantee of zero noise. Prior default-authority controls left the CSV correction awaiting approval; applying it now is an intentional contract improvement. The fresh-generation cases are not an exact before/after comparison with every earlier snapshot.

Validation: 3,915 tests passed, zero failed (116.45 seconds); release validation and both strict plugin checks passed. The focused review contracts also passed (167 tests). Changes are uncommitted and unpushed.

Artifacts: `/var/folders/yr/rc1_m71d72zcl3zxwsdd75400000gn/T/ce-doc-calibration-0usupkiq`. The `before/` files preserve the touched blocks' starting text. Existing schema tiers, path coverage, R18, settled-decision protections and required output routes remain. The broad mechanical-only default is deliberately replaced; incident #1373 supplies the product-fork failure this narrower authority rule must prevent. Removed blanket omission triggers had no dedicated incident-backed mandate found beyond their inherited reviewer checklist; consequence-based evaluation now decides whether to emit a finding.

The sections below record earlier snapshots and experiments, not the current default edit policy.


## Retained changes and stopping bar

Current source has clearer opening outcomes in `ce-plan`, `ce-doc-review`, and `ce-code-review`, plus restated document-review admission, recommendation, and correction checks. Existing permission and independent-review boundaries remain. The target is a substantial reduction in unnecessary decisions while preserving useful review and edit boundaries. It is not a zero-error guarantee across every run. The added mandatory remedy-validator experiment below is not retained: its cost and extra machinery did not demonstrate a consistent improvement.

| Retained version: tested path | Model / effort | Result |
|---|---|---|
| Large planning replay, latest planner outcome | Codex CLI, `gpt-6-astra`, low | Six useful grouped corrections, zero proposals or unresolved choices; independent artifact grading passes |
| Large planning replay, latest planner outcome | Claude Code, `claude-fable-5-1`, low | 13 reported fixes, one proposal, zero decisions; substantially fewer requests, but verification methods do not prove their claims and independent-review input contains leading questions |
| Code review through `ce-work` | Both models above | Ownership guard and meaningful 403/404 tests applied without user decisions; independent test reruns pass 5/5 on each |
| Default / granted document-edit authority | Both models above | Default preserves the approval boundary; granted path fixes CSV verification while preserving the unresolved retention choice |

The retained version’s last Fable run improves question volume, with concrete remaining correctness limitations. Its U1 fixes density at three distinct devices. On re-examination, this is an unnecessary precision concern, not a demonstrated product-authority violation: the original contract leaves “several” undefined and protects the two-device example. The threshold alone does not fail the permission boundary. Its local reviewer receives diagnostic questions derived from the peer review, so a real separate worker and terminal receipt do not establish independent corroboration. Its eval plan still treats forced skill loading as positive activation evidence and trailer claims as evidence of actual invocation. The remaining parity proposal lacks a demonstrated need. These defects remain visible; they are not counted as successful autonomous corrections.

Code-work execution ordering has a separate limitation: Fable simplified after review, while Astra began review before one simplification result returned. Neither fully proves the repository's required ordering. The intended rule remains simplification completed before the first review, with another pass only after material implementation changes.

Final validation: **3,915 tests passed, zero failed**, release metadata and both strict plugin validations passed, diff check clean. Changes remain uncommitted and unpushed. The latest planning runs are in `ce-plan-outcome-retry-2dqify1w`; current-copy code runs are in `ce-native-review-kz6qv9xe` (full paths below). Earlier mixed-version runs and timeouts are qualified in the history rather than counted as final evidence.

## Experiment history


**Evaluation correction:** the larger replays through `ce-outcome-review-jvbybded` contained stale native skill copies alongside updated bundled skills. The final Fable run demonstrably loaded the old native copy. Their behavior is recorded below but cannot establish the latest complete workflow's performance. Corrected replays under `ce-native-review-kz6qv9xe` synchronize and verify every callable copy in each host workspace. Standalone authority-control fixtures did not contain those stale sibling copies.


Date: 2026-09-09

The live code-review/work tests pass the targeted autonomy checks on both Claude and Codex: real ownership defects are fixed without user questions, regression tests pass, and speculative review residuals are omitted. The larger planning replay is still host-dependent. Codex ends with five supported corrections and no pending items. Claude ends with twelve applied corrections and seven proposals, with no separate decisions or FYIs, but still over-edits and forwards unnecessary suggestions. This is meaningful progress, not proof that the initial calibration goal is fully achieved.

The follow-up restored a blocked independent-verification path, separated technical judgment from edit permission, and made the caller own the final review disposition. Complete results, including failed intermediate attempts, are retained below. Changes remain uncommitted and unpushed.

**Model qualification:** the failed final Claude-hosted run records `claude-fable-5-1`; its reasoning level was not captured. It was not an established Opus 5 result, and it did not establish failure at Fable 5.1 low. See the explicit model/effort rerun at the end of this report.

## What was tested

Fresh Claude and Codex CLI processes loaded extracted on-disk skills in isolated fixture workspaces. Full planning fixtures also carried matching copies of sibling skills. No installed plugin cache was edited. Direct-review runs dispatched reviewers; planning runs authored a draft and invoked document review. These runs stopped at the first user-facing boundary, without answering approval menus or implementing production changes.

Baseline: `153e605e1622154a0d7da095fceed13edcb68bf7`, before this PR's review changes. The initial comparison used pushed head `2f91f391c1cca9763c66cd98e6dc687886fb6382`. Later runs used successive working-tree snapshots, not that commit. Each run's `input-manifest.json` records its exact inputs; the extracted skill files and frozen sibling copies remain with the run. Do not treat results from an intermediate snapshot as final-tree evidence.

Artifacts for this evaluation are under `/tmp/ce-review-live-bz5uglfu/`. This path is local scratch, not a permanent downloadable result. The tracked fixtures and scenario catalog preserve repeatable inputs. Runtime evidence identifies Claude `claude-fable-5-1` (reasoning setting not captured) and Codex `gpt-6-astra` with low reasoning. Models were supplied by the host sessions rather than forced through a new API configuration.

Cross-model review was disabled in both arms of the live workflows to isolate native review and caller behavior. A separate supplied-peer test checked the existing peer-only approval restriction. Claude dispatch was verified from actual tool calls and child-session logs. Codex output included reviewer returns and collaboration wait events, but the captured CLI transcript did not independently establish the complete dispatch roster. Its reported reviewer counts therefore have weaker provenance.

## Outcome checks

The evaluation counts work the user is asked to assess, not just the number of menu questions. Combining two unnecessary edits into one confirmation is still two unnecessary edits. Moving a decision to FYI is not successful filtering.

The source-backed direct-review fixture contains a real defect: a plan reverses the existing report loader's arguments, causing a reproducible TypeError. Existing document contracts already require ownership checks and 403/404 verification. Requests to repeat those requirements in individual units are unnecessary unless evidence shows the existing contract cannot guide implementation. A minor incorrect section reference is a real correction, but missing it is not a material safety failure. Header casing preferences and unspecified spreadsheet integrations do not establish defects.

The permission fixture contains three supplied findings: a broken comma-splitting verification method, an unapproved retention choice, and a request to duplicate a quoting rule already referenced by its implementation unit. Success means correcting the first only when authorized, preserving the retention choice, and rejecting the duplicate rule.

## Results

### Full review and planning

| Host and workflow | Baseline | Initial PR head | Revised behavior |
|---|---|---|---|
| Claude standalone review | One unnecessary owner-check proposal, one casing FYI, three residual concerns and one duplicate deferred question; one minor fix applied | Two unnecessary proposals in one confirmation, one casing FYI; real loader defect fixed | Latest standalone run fixed both real errors and removed casing FYI and the redundant ownership proposal, but still proposed repeating the required 403/404 tests in U3 |
| Codex standalone review | Real loader fix awaited approval; no unnecessary findings | Real loader fix applied; no unnecessary findings | Latest standalone run fixed the loader with no proposals, decisions, FYIs, or residual concerns |
| Claude planning with review | Three unnecessary decisions, one FYI, and a deferred header question | No separate decisions, but one proposal, one FYI, and residual noise; caller applied the proposal while still reporting it as pending | Planner's explicit grant allowed one verification correction without approval. No separate review decisions remained, but an unnecessary spreadsheet FYI and a trusted-input residual concern remained |
| Codex planning with review | No findings or review decisions | No findings or review decisions | No findings or review decisions; no demonstrated improvement over its already-clean baseline |

Artifact directories: `direct-pre`, `direct-current`, `direct-revised`, `direct-final-valid`, `plan-pre`, `plan-current`, and `plan-final`. The final planning and standalone runs predate the small output-count reconciliation described below. One aborted direct-review launch used a planning fixture without PLAN.md; `direct-final` is invalid and excluded. Its corrected replacement is `direct-final-valid`.

### Focused generation and transcript replay

The coherence-only advisory fixture was run before and after removing conflicting admission instructions, with one intervening revision. Codex consistently returned concrete contradictions without harmless FYIs. Claude's latest generation still included a punctuation preference, although residual and deferred fields were empty. This is a filtering failure, not grounds to lower confidence thresholds further. A coherence-only run cannot establish whole-review feasibility coverage.

The historical review replay (`transcript-final/ce-doc-review__ownership-transcript/post`) tested an intermediate snapshot, before the new caller grant. Claude retained **nine decisions and four FYIs**. Codex retained **eight grouped proposals, zero separate decisions, and zero FYIs**. The fixture omits the source repository and raw reviewer anchors, so some claims remain unverifiable. Neither fewer menu questions nor Codex's disposition alone proves that the original workflow problem is solved. Earlier reports remain historical records; their counts have not been relabeled as current results.

### Permission controls

| Input | Claude | Codex |
|---|---|---|
| Explicit correction permission, before the new authority wording | Corrected verification; preserved retention; rejected duplicate rule | Same |
| Explicit correction permission, revised authority wording | Corrected verification; preserved retention; rejected duplicate rule | Same; also restated the existing retention blocker |
| Default review permission, revised wording | No edits; verification correction proposed for approval | Same; also restated the existing retention blocker |
| Explicit permission, but findings supplied only by a cross-model peer | No edits; verification correction still requires approval | No edits; verification correction still requires approval |

Explicit permission already worked in the focused pre-change control. The new behavior is the planner reliably carrying its existing authority into the review handoff and the reviewer resolving that authority in one place. It is not evidence that a new review mode was needed.

Claude's peer-only result repeated the same proposal under two headings and narrated rejected findings. The approval boundary held, but presentation still contains avoidable noise. The permission controls also verified workspace diffs rather than relying only on the agents' claims.

Artifact directories: `authority-before`, `authority-final`, `authority-default`, `authority-peer`, and `authority-count-final`.

## Changes and why they belong here

- **Reviewer generation:** the shared rubric now requires worthwhile consequences across findings, residual risks, and deferred questions. Persona-specific instructions to emit harmless preferences were removed. Missing repetition of an existing requirement is not missing work.
- **Synthesis:** retained defects are assessed against existing edit authority. Verified corrections may apply within a supplied document-edit grant. Product choices, constraints, session-settled decisions, and peer-only restrictions remain protected. Non-interactive mode and reviewer confidence do not grant permission.
- **Planning handoff:** when the user authorized revising the draft, `ce-plan` passes that authority for implementation and verification corrections needed to satisfy the established Product Contract. It does not apply a returned proposal to bypass a review restriction.
- **Output:** final routes determine applied and pending counts. Already-applied corrections must not reappear as approval work. Rejected findings must not return through the residual-concern template.

The independent skill review found two remaining contradictions in output rules: all entailed corrections were still counted as pending proposals, and below-threshold residuals were still admitted “for transparency.” Both were reconciled with the owning synthesis rules, and the independent reader verified their closure. A focused fresh-agent repeat (`authority-count-final`) applied the verification correction on both hosts and reported zero pending proposals, preserving the unresolved retention choice. The output-template membership changes received static review and mechanical checks, not a separate full interactive replay.

## Authoring review and provenance

The shared confidence rubric originated in `6caf330363` (#622); session-settled review handling originated in `d380903ebf` (#1136). The confidence-scoring learning records earlier attempts to handle volume through menus and batching. The removed mandates protected advisory output availability, but also explicitly admitted harmless preferences. The shared consequence requirement now decides admission; anchor 50 remains available for useful advisory observations. Existing confidence routing tests remain intact.

The approval barrier also has a documented failure behind it: U14 in `docs/plans/2026-08-12-003-fix-doc-review-decision-clustering-plan.md` records auto-application choosing product forks. That barrier was not removed on the basis of confidence or reversibility. A bounded user/caller grant now decides whether a correction may apply; unapproved outcomes and peer-only findings retain their existing protection.

The old advisory fixture answer key required four harmless FYIs. It was updated to the current admission contract, while earlier results retain their historical interpretation. This is an intentional oracle change, not a claim that previously failing behavior passed unchanged.

No full skill sweep was performed. Untouched walkthrough mechanics, reviewer activation, broader persona rubrics, and other callers remain outside this follow-up. No new permission to publish, commit, implement code, or select product behavior was introduced. No separate learning file is needed: this report and the updated authoring/scoring guidance preserve the durable reasoning.

## Validation and reproduction

- `bun run test`: **3,909 passed, 0 failed**.
- `bun run release:validate`: passed.
- `bun run plugin:validate`: both strict validations passed.
- Focused pipeline/review contract and eval-catalog tests: **167 passed, 0 failed** after the output reconciliation.
- `git diff --check`: passed.
- `ce-simplify-code`: reuse, quality, and efficiency reviews found no implementation simplification needed. The only quality finding was an unreferenced permission fixture; default/granted scenario rows now reference it.

Tracked scenarios include `ce-doc-review/live-review`, `advisory-admission`, `default-edit-authority`, and `granted-edit-authority` in `tests/skill-eval-cell/calibration-scenarios.ts`. Catalog grading checks execution/read/delegation shape; the behavioral verdicts above require reading responses and workspace diffs. Keyword success is not a substitute for that judgment.

A standalone live current-tree run can be repeated with:

```sh
bun run test:skill-eval-cell -- --skill ce-doc-review --ref WORKTREE --hosts claude,codex --fixture tests/skill-eval-cell/fixtures/review-live --task "Use ce-doc-review to review PLAN.md. Inspect source and dispatch real reviewer subagents. Retain reviewer returns in the workspace. Do not publish, commit, or modify production source." --git-init --out /tmp/ce-review-live-repeat --timeout-secs 600
```

Use a fresh output directory per run. For paired planning, start from the review-live README/source without its seeded PLAN.md, provide matched extracted sibling skills for each arm, and request `ce-plan` to write `docs/plans/csv-plan.md` including its normal document review. The frozen inputs and task files in the artifact root preserve the exact runs reported here.

## Limit after the first iteration

This bounded iteration supports the permission distinction and exposes real improvements on the planning path. It does not justify saying that CE now drastically reduces unnecessary decisions reliably across models. Further tuning should address contradictory owning-layer rules or repeatable causes found in fresh workflows, rather than append examples for every surviving nit.


## Follow-up: caller ownership and code review

A second bounded iteration tests the caller's final judgment, not just reviewer wording. Its artifacts are under `/tmp/ce-review-ownership-fsc8mfkj/`; these are local scratch. Each directory retains its input manifest, extracted skill, frozen sibling definitions, host outputs, and workspace changes.

The earlier `ce-plan` handoff required verbatim reviewer output and derived its menu from original counts. That came from #1239 (`b7a09f4035c33ba006939593f89c5e4e304f0201`), which protected readable presentation. It did not establish that every reviewer claim was valid. The caller now judges the completed plan and computes output from remaining worthwhile findings, while preserving the readable structure of retained findings and the original evidence. Application remains with `ce-doc-review`.

`ce-doc-review` now separates choosing a technical correction from permission to apply it. The agreed outcome and constraints decide whether the agent can choose a remedy; the application section decides whether it may edit. Adding necessary implementation or verification detail does not itself create a product decision. Product choices and peer-only approval restrictions remain protected.

| Scenario | Claude | Codex |
|---|---|---|
| Saved small review, before caller change (`caller-before`) | Forwarded unnecessary spreadsheet and future-input concerns | Forwarded both concerns |
| Saved small review, after caller change (`caller-after`) | Removed future-input concern; spreadsheet FYI remained | Dismissed both; no unresolved findings |
| Full planning with real document reviewers (`plan-live`) | Applied one content-type consistency fix; no remaining review findings or decisions | Four reviewers returned clean; no review decisions |
| Supplied transcript after separating remedy choice from permission (`transcript-choice`) | Seven grouped proposals, seven decisions, four FYIs; still noisy | One proposed register decision remained; other claims largely dismissed |
| Explicit edit grant (`authority-choice`) | Corrected broken CSV verification; preserved unresolved retention choice | Same |
| Original larger plan with reconstructed source (`large-caller`) | Eleven corrections, five unnecessary decisions and five FYIs; also bypassed peer-only application protection | Seven corrections, no unresolved review items; dispatched fresh reviewers |

The larger source fixture uses the parent of the implementation merge, `fe74844c8edd9f3a09a3ab2243fb32a4d4e39f73`, with the supplied plan and review. It is a reconstruction, not the exact original worktree. Its historical user output is not a matched baseline. Claude's zero-question mutations cannot be counted as success where they bypassed the existing peer-only rule. A fresh reader found that preserving the Product Contract did not require the five remaining decisions: verification could carry necessary grading detail, while the other claims did not establish a conflict or missing outcome. The final caller restatement makes the completed-plan goal and the consequence required to retain a claim explicit, and returns application to the review owner.

A separate reference control (`reference-control`) loaded the reference plugin's published lead-judgment framework into the same Claude CLI transcript task. It still returned five user decisions and eleven grouped proposals. This is a framework-only control, not an end-to-end test of that plugin in Cursor. It supports investigating caller ownership and context rather than assuming a short judgment paragraph alone explains the observed experience.

### Code workflow comparison

The code fixture adds a private-export signed-link endpoint with a missing ownership guard. Its initial three tests pass despite the leak. Success requires reporting the defect in report-only review, then having `ce-work` reuse the existing guard and add 403/404 regression tests without asking, changing retention policy, committing, or publishing. Hypothetical provider infrastructure and mismatched loader IDs have no supported role in the requested work.

| Scenario | Claude | Codex |
|---|---|---|
| Baseline standalone code review (`code-review-pre`) | Found ownership defect and missing rejection tests; repeated concerns in residual/testing fields | Failed before dispatch because it interpreted collection as requiring one blocking tool |
| Intermediate standalone review (`code-review-post`) | Found both defects; hypothetical loader-ID risk and duplicate testing concerns remained | Real reviewer and validator batch completed; two justified findings, empty residual fields |
| Baseline work with review (`code-work-pre`) | Fixed ownership and rejection tests; five tests passed without user decisions | Same; no residual findings |
| Intermediate work with review (`code-work-post`) | Fixed both findings; five tests passed without asking, but repeated a hypothetical test gap in handoff | Fixed both through two workers; five tests passed, no justified residuals |

The shared code-review template still said not to suppress advisory observations, and synthesis explicitly moved unproven runtime concerns into residual fields. Those instructions contradicted admission. The rewritten blocks require a demonstrated benefit in every output field. `ce-work` retains rejected-claim reasons with the review evidence rather than repeating them as deferred concerns.

The Codex collection failure exposed an unrelated but blocking portability defect on this path: the rule required one tool to accept an ID, block, and return the result. The host instead offers native waiting and separate terminal-result delivery. The replacement preserves the terminal-state and consumed-result requirement, complete reviewer roster, malformed/error handling, slot release, validator fallback, and peer cleanup. It accepts separate host capabilities. A fresh reader verified the protections from #1214 and #1530 remain. Contract tests now assert those conditions instead of a single collector shape.

Current mechanical validation: `bun run test` passed 3,915 tests with zero failures; release validation, both strict plugin validations, and `git diff --check` passed. These checks protect contracts and fixtures, not behavioral judgment. The code fixture and catalog changes received the required reuse, quality, and efficiency reviews with no remaining findings.

To repeat the work/review integration, copy `tests/skill-eval-cell/fixtures/code-review-live/` into a fresh OS-temp directory. Place a frozen copy of the arm's skills at `bundled/skills/` in that fixture. Run `test:skill-eval-cell` with `--skill ce-work`, that fixture, `--git-init --git-staged src/endpoint.js,endpoint.test.js`, and this task:

> Resume ce-work at Phase 3 quality check for PLAN.md. The staged endpoint implementation and tests are my work for this request and are yours to review and fix. Run the normal ce-code-review and caller-owned followup, including real reviewers and any applicable fix workers. Finish local verification and handle residual findings. Use bundled/skills for sibling invocations. Do not commit, publish, create tickets, or make a retention policy decision.

Use `--hosts claude,codex --timeout-secs 900`, a fresh output directory, and a matching `--ref` for each arm. The standalone counterpart is the tracked `ce-code-review/live-review` scenario. Neither scenario's execution-shape grade alone establishes the behavioral verdict; inspect review artifacts and the source/test diff.

### Follow-up results

`large-caller-final` still failed on Claude: seven fixes applied, eight proposals, one decision, five FYIs. It preserved peer-only approval, unlike the preceding run. Codex applied four corrections and left no unresolved review items. The next change requires a saved resolution before application or presentation, so the caller must judge rather than relay the historical worklist. In `large-caller-resolved`, Claude applied six corrections, retained seven peer-only proposals and two decisions, and dismissed all five FYIs. That is actual filtering progress, but the remaining user work still exceeds the intended bar. In particular, the proposed numeric tell threshold and register restriction introduce unsupported policy rather than cure a demonstrated defect.

In `code-review-final`, Claude completed four actual reviewers and an independent validator. It retained the ownership defect and missing rejection tests, with empty residual and testing-gap fields. It did not edit source. The ownership fix still carries `manual` classification, although the integrated caller correctly handles it without asking; report-only JSON is not evidence that standalone `apply:local` would do so.

In `code-work-final`, Claude completed reviewers, validator, and a fix worker; the independent reader verified terminal tool results in session `61d467b5-1900-4abf-a80e-e5f4065a97fe`. The fix places `assertOwner` before signing. The new 403 test asserts that signing never runs, and the other new test asserts 404. An independent `node --test` run passed all five tests. Scope and retention remained unchanged, and no user decision was requested. The caller nevertheless skipped the user's ten-line simplification threshold and added misleading rollback advice about increased 403 responses—the intended security fix itself can cause that increase. Those are separate instruction/handoff failures, not failures of the source fix.

The owning shipping blocks now select the project's simplification threshold before the default and require operational advice to distinguish intended change from regression. Monitoring material belongs in the shipping handoff; local completion does not require extra deployment advice. The checklist refers to the selected threshold rather than repeating the default. The operational-validation mandate remains; this change removes invented guidance, not the required PR section. The previous mandate is traceable through the root migration #967 (`02b72bc8a`). `code-work-gates` repeats the full integration after these changes.

Latest mechanical checks after the saved-resolution and shipping changes: 3,915 tests passed, zero failed; release and strict plugin validation passed. No new fixture implementation was added after the completed simplification reviews. The completed `code-review-final` results on both hosts contain only the ownership defect and missing denial/404 tests, with empty residual fields and unchanged implementation. `code-work-final` on Codex applies both corrections, runs simplification before review, passes all five tests, and leaves no residual findings. In `code-work-gates`, Claude also removes the misleading monitoring advice and performs the three simplification reviews, but still performs them after code review. This timing violation remains; the core review/fix autonomy result passes. The remaining final cells are recorded below.


### Restoring independent verification on resume

The saved-resolution trial exposed a workflow contradiction rather than another missing warning. R18 allows a peer-originated correction to become eligible after an in-process reviewer independently identifies the same issue; #1373 (`421a33781`) preserved that condition. But the completed-review resume rule prohibited redispatching any persona. This forced already authorized corrections into an approval batch even when a limited independent check could resolve them.

The resume rule now preserves completed coverage while allowing a necessary local check of the relevant document/source slice. Synthesis obtains that check when missing corroboration alone blocks a worthwhile, otherwise authorized correction. The verifier receives the outcome and constraints, not the peer's verdict or proposed wording. Parent inspection is still not independent corroboration; missing, failed, or disagreeing evidence leaves the restriction intact. R18 and the edit-authority checks remain. The guide documents this distinction.

`large-caller-corroboration` tests the restored path through the real planner. `peer-check-allowed` and `peer-check-forbidden` use identical peer returns for a broken CSV verification method, an unapproved retention choice, and a redundant rule. The first permits a limited independent check; the second expressly prohibits new review. Success means only the supported CSV correction can apply after real independent verification, retention remains untouched, the redundant suggestion is rejected, and a no-dispatch restriction cannot be bypassed. Both hosts applied only the CSV correction after a real independent check in the allowed run, and neither edited or dispatched in the forbidden run. Claude's allowed run still surfaced an unnecessary retention-owner residual; that is a filtering failure, not an edit-authority failure. The independent reader verified Claude's prompt excluded the peer verdict and wording, its terminal finding arrived before the edit, and only U2 changed. Session: `d4213bf7-5d01-4b89-9377-f5242f1a4ebd` (dispatch 09:08:54 UTC, terminal result 09:09:07, edit 09:09:22).

These controls use the tracked `doc-review-edit-authority` fixture unchanged. The task establishes that `REVIEW.json` is peer-only with no prior local corroboration, grants implementation/verification corrections while preserving the Product Contract, and either prohibits new review or allows the necessary limited local check. No fixture oracle was changed to make an unauthorized retention edit pass.


### Why zero questions was not enough

`large-caller-corroboration` on Claude reported 17 corrections and zero pending items, but independent grading rejected a clean-success verdict. It introduced a three-device writing threshold, required all seven writing tests in every sibling invocation line, and added guard tests without demonstrating that their absence blocked the outcome. These edits narrow behavior or reintroduce the duplication the work aims to remove. Keeping Product Contract text byte-identical is not proof that implementation preserves its meaning.

The local reviewer was separate and returned before edits, but its prompt contained nine diagnostic questions shaped by the historical review. It did not receive the verdicts or proposed fixes; that was insufficient to prevent confirmation of the original framing. It also used a generic exploration persona instead of the normal calibrated reviewer prompt.

The final intake revision requires the normal reviewer prompt/output contract, a fresh context that has not seen the peer review, and only the relevant source, agreed outcome, and constraints. It excludes peer-derived diagnostic questions as well as claims and proposed fixes. The independent reader found no loss of existing permission, resume, or evidence protections. `large-caller-independent` tests that change; its grading must inspect edits, not merely count interruptions.

Final `code-work-gates` results on both hosts resolve the ownership defect without questions, preserve scope, and leave no review residuals. Independent reruns pass all five tests on each host. Claude's simplification timing remains wrong (after review), while its misleading monitoring advice is gone. This is a bounded review-autonomy result, not a claim that every part of `ce-work` executed perfectly. Both code hosts also succeeded at automatic fixing in the baseline; the demonstrated improvement is restraint in reporting, not newly acquired ability to apply this fix.


Codex's `large-caller-corroboration` result applied eight supported corrections and left no unresolved items. Independent grading found no numeric device threshold, copied seven-rule caller blocks, register narrowing, or speculative FYIs. Retained edits address dependency sequencing, setup routing, current inventory, unavailable-skill behavior, executable eval placement, required coverage, and usable grading. A real `plan_corroboration` spawn is recorded in session `01a08574-4eee-7a60-afc0-82b88eabc110`; its prompt is encrypted in the session log, so the claimed absence of peer framing is reported provenance rather than independently verified. This result supports the policy path, while Claude's preceding result demonstrates remaining host-dependent over-editing.

The final source passes all 3,915 mechanical tests (zero failures). Focused contracts after the last intake change pass 106 tests. Release and strict plugin validation passed; the subsequent intake-only change does not alter manifest or inventory data. No files have been committed or pushed during this evaluation follow-up.


## Final assessment

| Final scenario | Claude | Codex |
|---|---|---|
| Standalone code review, `mode:agent` | Real ownership defect and missing rejection tests only; no source edits or speculative residuals | Same |
| `ce-work` with real review and fix workers | Correct guard and regression tests, 5/5 tests, no user decisions or residual findings; simplification timing still wrong | Correct guard and regression tests, 5/5 tests, no user decisions or residual findings |
| Peer-only correction with independent checking allowed | Corrected U2 only after a real independent result; retention preserved; one unnecessary residual observation | Corrected U2 only; retention preserved; no residual concern |
| Peer-only correction with new review prohibited | No dispatch or edits | No dispatch or edits |
| Larger planning replay with final independent-review instructions | 12 applied, 7 proposed, no separate decisions/FYIs; still over-editing and approval noise | 5 applied, no unresolved items |

In the final Claude planning run, the generic local reviewer used the ordinary feasibility prompt rather than the earlier issue checklist. It launched at 09:23:09 UTC, returned at 09:26:51, and edits began at 09:28:28 (session `6cb0a0f2-f0fa-4ab6-b6e5-426567f2757f`). The lead rejected a suggested eval-tool expansion and chose fresh host sessions instead. It did not apply the numeric threshold and rejected the register restriction.

Remaining Claude failures are concrete: the numeric threshold, extra parity definition, and stricter instruction-equivalence predicate remain proposed; U3 still copies seven rules into sibling instructions; unmeasured-host fallback behavior is asserted without evidence. The Goal Capsule edit restates the settled opt-in choice and is not graded as an unsafe product decision. Exact catalog-heading spelling is also counted as a defect despite the existing category direction being adequate. Product Contract text remaining unchanged is insufficient to establish that the resulting plan preserves scope and behavior.

The broad goal is therefore not declared complete. The code path and bounded independent-verification controls demonstrate that CE can act autonomously while preserving the tested boundaries. The remaining work is document judgment on Claude, especially avoiding unnecessary edits as well as unnecessary questions. Further additions for individual examples would violate the authoring standard; no such case catalog was added. The final source review found no new missing permission or independence condition to patch. The remaining behavioral failures stay visible instead of being relabeled as success.


The final independent reader confirmed Codex used two real `fork_turns: none` reviewer spawns. Their prompt payloads are encrypted, so exact input contents remain unverified. Its five edits pass the targeted scope/noise check, but the review leaves the original stale inventory count uncorrected. Neither this result nor the sampled caller comparisons establishes complete defect detection or universal nonregression.


## Model and effort clarification

The failed final Claude-hosted planning run used **`claude-fable-5-1`**, as recorded on all 35 assistant messages in session `6cb0a0f2-f0fa-4ab6-b6e5-426567f2757f`. The preceding larger run (`71653756-1748-4cf8-bf1f-e2f917069db7`) and successful smaller planning run (`7127ce79-8fe5-47dc-96f9-1305dc21a056`) also record `claude-fable-5-1`. These results are not evidence of an Opus 5 failure.

The earlier driver did not pass `--effort` or capture the session's effective reasoning level. Therefore the prior results cannot establish whether **Fable 5.1 low** fails. Describing the issue only as a “Claude path” failure omitted a material qualification.

A new matched run pins `--model claude-fable-5-1 --effort low` through a run-local CLI wrapper, preserving the task and reconstructed source fixture and injecting the current skill files. It does not change installed plugins or user settings. Its requested runtime is recorded alongside the artifacts at `/var/folders/yr/rc1_m71d72zcl3zxwsdd75400000gn/T/ce-fable-low-4qzmfw2n/`. The cell's recorded argv names the wrapper; `requested-runtime.json` records the real executable and explicit overrides. Subagents still follow the skill's own model-selection instructions; this pins the orchestrator, not every reviewer tier.


A fresh grading audit also corrected an overstatement: the final Claude Goal Capsule edit restates the opt-in behavior already established by R10/KTD5. It is not an unsafe new product choice. The task names implementation/verification edits but does not explicitly prohibit every other section, so any section-scope concern is narrower than the earlier authority-failure language implied. Likewise, not all seven proposals are nitpicks: safety/mode coverage, caller comparisons, and useful grading can warrant corrections. The stronger residual failures are unsupported numeric/parity/equivalence policy proposals and duplicated writing rules in caller fallbacks. This correction supersedes the broader grading language above.


### Explicit Fable 5.1 low replay

The matched run completed successfully as a process, with no timeout. All 38 parent assistant messages record `claude-fable-5-1` in session `15aa50c3-f86e-4c80-bb91-daa30a39481b`; the observed launch explicitly supplied `--effort low`. Task, starting workspace, injected skill, and harness fingerprints match `large-caller-independent`. The earlier effort is unknown, so this comparison cannot establish that a difference was caused by lowering effort.

The caller reported **11 applied fixes, four proposed fixes, one decision, and zero FYIs**. It dismissed the numeric threshold, extra parity definition, instruction-equivalence predicate, objective qualifier, and previously deferred scope questions. It preserved the Product Contract text and applied useful corrections to inventory, setup routing, and runnable verification. It still copied all seven writing tests into sibling fallback instructions, undermining the consolidation objective.

The four proposals concern an asset dependency, the learning Sources link, additional sibling comparisons, and skip-check fixtures. These are not four proven nitpicks: their value differs, and the peer-only rule correctly prevents applying uncorroborated peer suggestions. The workflow nevertheless leaves technical review work with the user. The remaining product decision proposes restricting edits to the user's writing to sentence splits and actor restoration without demonstrating that the existing minimum-edit condition fails. Asking before such a change respects authority; admitting the unsupported restriction is the calibration issue.

This single explicit-low replay therefore does not meet the full document-calibration target. It shows stronger rejection of several historical suggestions than the preceding run, while retaining unnecessary approval work and an over-prescribed fallback. No skill prose changed during this comparison. Process completion and fewer questions are not treated as proof that all retained changes are worthwhile.

Independent grading also found a concrete incorrect correction: the new U6 plan prescribes `must_not_include` for prose punctuation and first-person checks, but the fixture's `grade.ts` applies that field only to the `TEAM:` roster and requires that trailer. It would not validate the proposed prose behavior. Excluding the em dash and triad also conflicts with the restraint example that should remain unchanged. This confirms that counting automatic fixes alone overstates success. The source fixture was inspected to verify the grader's finding.


## Remedy-check restatement

Authoring runtime: Codex, GPT-6 family. A strong authoring model can supply judgment that literal readers do not, while repeated failures can tempt the author to prescribe each observed case. This iteration therefore replaces two existing synthesis blocks, not the reviewer roster or approval policy.

Admission now evaluates the consequences of carrying out the existing plan rather than its distance from a preferred rewrite. The final correction check now establishes that the remedy solves the retained problem, matches actual interfaces when it prescribes a mechanism, and adds no unnecessary requirements. Authority remains a separate check. This serves both standalone review and planner-owned review.

Provenance: the earlier admission block is present in `f8280a8a1`; its safeguards against unsupported preferences, repeated requirements, and advisory leakage remain expressed by the unchanged-plan condition. The old final check primarily protected permission, mechanical corrections, and visual aids; those conditions remain. No permission or independent-review mandate was removed. The restatement removes overlapping judgment wording, not a required gate. An independent reader compared the complete old and new blocks and found no material meaning drift or lost path. Untouched workflow sections remain outside this iteration.

Matched fresh replays are under `/var/folders/yr/rc1_m71d72zcl3zxwsdd75400000gn/T/ce-remedy-check-twqc0kob/`. Both parents have explicit model/effort overrides: Fable 5.1 low on Claude Code and Astra low on Codex CLI. Codex session `01a0872a-8c4e-7621-bb88-df9a29885019` records `gpt-6-astra` and `effort: low`. The same task and source fixture are retained, with the revised bundled review skill. Separate existing authority fixtures test the default approval boundary and a supplied grant without permitting a product-choice change. Outcomes follow below when graded.


The first restatement replay on Astra low made two supported corrections and returned no unresolved items. Independent grading found no numeric threshold, copied rule list, register restriction, or changed Product Contract. The smaller default-authority controls on both hosts left U2 unapplied, while granted-authority controls corrected U2 and preserved retention. Fable's granted run nevertheless surfaced retention as a Skip decision and implied that unrelated implementation waited for it. This is an adjudication failure, not an unauthorized retention edit.

An independent source audit found two conflicting instructions: 3.5b assigned Skip to retained findings while defining Skip as rejection; the competing-remedies explanation let the desire to accept a proposed remedy create a user decision. Both blocks are now restated around whether a consequential unresolved choice survives. The schema's Skip value and the user's interactive Skip action remain; #1373's genuine which-remedy presentation is preserved.

At the user's request, the document-review opening now states the usable-document outcome and distinguishes serious consequences from the amount of detail. Code review previously began with artifact-root mechanics and lacked an opening outcome; it now begins with the intended correct-change outcome and required completion condition. Existing review, validation, report-only, and application boundaries remain. An independent reader found no lost path or material meaning drift. The frozen final replay is under `/var/folders/yr/rc1_m71d72zcl3zxwsdd75400000gn/T/ce-outcome-review-jvbybded/`.

Mechanical validation during concurrent live replays completed with 3,904 passes and 12 failures, primarily subprocess timing checks and timeouts (300.57 seconds). This does not establish a source regression or a clean suite. A rerun after live work finishes will distinguish those possibilities. Focused review contracts remain green (106 tests); release and both strict plugin validations pass.


### Final outcome-opening trials

Astra low's larger planning trial completed with four grouped corrections and zero unresolved items. Independent grading verified setup routing, inventory, executable evaluation, and preservation-check changes against the actual diff. No product-policy threshold, duplicated writing rules, register restriction, or unsupported host waiver was introduced. The Product Contract and settled decisions remain unchanged. The resolved review records local corroboration for preservation coverage; the grader did not independently inspect that follow-up prompt.

Both final granted-authority trials changed only U2's broken CSV verification and returned no decision. Fable still explains rejected suggestions twice in its output, which is presentation noise; it no longer asks the user to decide retention or blocks unrelated units behind that choice. Astra returns only the applied correction and coverage. This demonstrates the boundary on the small fixture, not a universal reduction in review noise.

For comparison, the intermediate Fable large-plan run (before the opening and routing reconciliation) reported 11 applied fixes, six proposals, and one unsupported numeric-threshold decision. The first two-block restatement alone did not solve its calibration problem. The final large Fable result is recorded separately below.


### Native invocation provenance correction

Claude session `62cfec23-3746-4320-8cfd-a90ff35b99eb` invoked `Skill ce-doc-review` at 17:27:09 UTC. The runtime loaded `.claude/skills/ce-doc-review`, whose opening and synthesis reference differed from the revised `bundled/skills` copy. The parent itself compared these files. This is mixed-version execution, not evidence that the revised opening failed. Astra explicitly read the current bundle, but stale discoverable copies also qualify its trial. Code fixtures had the same stale discovery surfaces, so those trials do not validate the new code-review opening.

The corrected fixture preserves the historical subject's `skills/` and replaces only workflow copies in `bundled/skills`, `.claude/skills`, and `.agents/skills`. Every file is hashed and compared, not just SKILL.md. The check also runs on each copied host workspace. Manifests and new runs live under `/var/folders/yr/rc1_m71d72zcl3zxwsdd75400000gn/T/ce-native-review-kz6qv9xe/`. Both model and effort overrides remain explicit. No source-skill edits were made in response to the contaminated result.


The two code runs under `ce-outcome-review-jvbybded` were deliberately stopped after discovering stale native discovery copies. They are interrupted, mixed-version trials, not passes or model failures. Corrected code runs under `ce-native-review-kz6qv9xe` use the same staged source, tests, task, model, and effort. Twelve native host-workspace copies across `ce-work`, `ce-code-review`, and `ce-simplify-code` match the frozen bundles file-for-file. The guide's existing fresh-context paragraph now requires this provenance check for callable sibling copies as well as the directly injected skill.


### Corrected-copy results and planner outcome

Astra's corrected-copy plan replay made six bounded corrections and returned zero proposals, decisions, or FYIs. Independent grading found no changed Product Contract, unsupported product restriction, or copied writing-rule fallback. The original stale inventory count remains uncorrected, so this is an autonomy result rather than exhaustive defect-detection evidence.

Fable's corrected-copy replay reported 18 fixes and six proposals with zero decisions. Independent grading rejects that as a clean result: U1 introduces the unsupported restriction to sentence splits/actor restoration; U3 duplicates the seven writing tests; U7 drops its required Sources-link verification while proposing extra work to add that link. The saved review calls the six proposals optional and says the plan is executable without them. The zero-decision count therefore hides approval burden and a product-behavior change. No native Skill invocation occurred in this run, but its explicit bundled reads and all discoverable copies were current. This is a real behavioral failure.

The final bounded experiment changes only `ce-plan`'s existing opening outcome from confidence/output emphasis to carrying out and checking the agreed work, preserving its outcome and constraints, resolving technical choices from evidence, and leaving adequate instructions unchanged. Output forms, WHAT/HOW/execution ownership, and the never-implement boundary remain in their owning blocks. The kernel is 7,880 bytes. Both models rerun the same original fixture and task with every callable copy synchronized; manifests live under `/var/folders/yr/rc1_m71d72zcl3zxwsdd75400000gn/T/ce-plan-outcome-ty400gx7/`. No additional case-specific prose was added.

Corrected-copy Fable code work identifies the ownership defect and missing denial/not-found tests, fixes both without user decisions, and leaves no residual findings. Independent `node --test` passes all five tests; signing is never called on 403 or 404. It still performs simplification after review, so this is not a claim that every execution-order requirement passed. The code-review opening preserved serious-defect detection in this fixture.


### Completion checks after interruption

The final planner-outcome trials both reached the 1,200-second timeout without a handoff or PLAN.md edit. Both stopped logging around 17:56 UTC, well before that deadline. Codex had saved dispositions and received a terminal independent reviewer result; Claude had only read the review instructions. The cause is unproven, so these are inconclusive trials rather than passes or behavioral failures. The unchanged experiment is retried once in fresh sessions under `/var/folders/yr/rc1_m71d72zcl3zxwsdd75400000gn/T/ce-plan-outcome-retry-2dqify1w/`, with actual host copies rehashed and verified.

Corrected-copy Astra code work also passes the autonomy fixture: the final diff adds only ownership enforcement and meaningful 403/404 tests, independent `node --test` passes 5/5, and no residual decisions or policy changes remain. Its simplification dispatch began before review but the quality reviewer returned at 17:43:57 after code-review dispatch at 17:43:26. Thus neither host fully obeyed the pre-review simplification completion rule: Fable ran it after review, Astra overlapped the two. This is a separate execution-order issue.

Final mechanical rerun: **3,915 passed, zero failed**, 153 files, 111.57 seconds. Release metadata, both strict plugin validations, and `git diff --check` pass. The previous 12 failures did not reproduce; no source or test change was made to suppress them. No commit or push was performed.


Final retry Astra passed independent artifact grading: six useful grouped corrections, zero proposals or unresolved choices, with no numeric threshold, restrictive user-edit policy, copied rule fallback, or reopened deferred scope. It preserves the Sources-link verification and routes reusable authoring guidance to the canonical standard. The larger verification section remains within already agreed requirements. This is non-regression on Astra, which also passed before the planner-opening change.

In the final Fable retry, the actual native `Skill ce-doc-review` invocation at 22:04:18 UTC loaded `/private/var/folders/yr/rc1_m71d72zcl3zxwsdd75400000gn/T/ce-plan-outcome-retry-2dqify1w/claude/hosts/claude/workspace/.claude/skills/ce-doc-review`. The returned body contains the revised outcome opening. Session `59ac739a-1e1d-46d3-80c6-804bea4d69c4` therefore confirms runtime loading as well as matching on-disk copies. Final behavior is graded separately from this provenance check.


Final Fable retry grading inspected the actual PLAN.md diff and session `59ac739a-1e1d-46d3-80c6-804bea4d69c4`. The local reviewer returned at 22:05:58 UTC and edits began at 22:06:27, so collection ordering is sound. Its prompt nevertheless asks about missing dependency IDs, verification versus file lists, named requirement fixtures, and the semantic already-present predicate—the same questions supplied by the peer review. This violates the current normal-review, fresh-context corroboration condition. No further case-specific instruction was added after this result. The final bounded round establishes the remaining limitations rather than a clean Fable planning pass.

## Independent correction check experiment

The lead already had explicit instructions to validate remedies, but the final Fable plan still contained verification methods that cannot prove their claims. Fresh, read-only checks of its before/after documents, without the prior findings or our diagnosis, found actionable defects on both requested models. Astra identified forced activation, substring-based preservation checks, and baseline invocation grading. Fable identified the unavailable sibling dependency in the single-skill cell and moved sibling/chat checks to native sessions. Neither check found everything. This supports testing an independent edit check; it does not establish that one extra reader guarantees correctness.

Artifacts: `/var/folders/yr/rc1_m71d72zcl3zxwsdd75400000gn/T/ce-remedy-audit-m1uq15nq`. The prompt, original and changed documents, explicit model/effort commands, and outputs are retained. Both processes completed.

The candidate change replaces the lead-only remedy check with a single independent check of meaning-changing candidate edits. It preserves R18 and edit authority, excludes mechanical fixes, and prevents rejected remedies from becoming approval requests. The validator receives proposed edits, so its findings cannot count as independent discovery under R18. Full integration completed on both models. Astra made supported corrections with no pending items. Fable made eight reported fixes and returned eight proposals, including redundant dependency/link instructions and unnecessary precision. Its validator accepted an invalid use of the grader’s `must_not_include` field for reply prose; that field grades `TEAM`. The new mechanism did not consistently improve the intended outcome and is not retained.

The first default-authority control after adding validation applied a meaning-changing edit on Astra without an explicit grant; Fable preserved the boundary. The validator itself made no permission claim. Moving the unchanged validation block before permission routing produced correct no-edit behavior on both hosts in fresh controls. This is bounded evidence about placement, not proof of a universal fix. Both granted-authority controls applied the CSV correction and preserved the unresolved retention choice. Some runs still repeated that existing choice as deferred context.

The final focused check completed on both requested models. Both identified the invalid reply-grading mechanism when the validation condition required distinguishing success from a plausible failure. Astra also rejected the forced-activation and substring-preservation claims. Fable still accepted most proposed additions, including redundant instructions, and missed other verification defects. This improves a bounded correctness check; it does not demonstrate the burden reduction needed to justify a mandatory validator. The candidate was recovered from the original snapshot and eleven exact successful edit payloads after the run cleaned its temporary copy. This checks the validation judgment only; it cannot establish that another mandatory worker improves the full planning workflow. Artifacts for this round are under `/var/folders/yr/rc1_m71d72zcl3zxwsdd75400000gn/T/ce-validated-remedies-c5jgxstq`, including `candidate-recovery.json`.

This round’s complete repository suite passed: 3,915 tests, zero failures, 133.55 seconds. Release validation and both strict plugin checks passed. No commit or push was performed. The remaining simplification-order limitation is unchanged; the code-review autonomy fixtures already passed on both requested models.

The mandatory validator, its walkthrough/guide changes, and its temporary scenario-contract changes were removed. The retained review prose matches the earlier frozen workflow at `ce-plan-outcome-retry-2dqify1w`; the 106 focused review-contract checks passed again after restoration. The experiment remains in this report so another author can distinguish useful remedy checking from a demonstrated improvement in review calibration.

A bounded read of `ce-brainstorm/references/handoff.md` found an additional caller-side amplifier: its post-review nudge is triggered by remaining P0/P1 labels. That caller path was not behaviorally tested or edited in this round. Review skills own filtering before standalone presentation; callers own reconciling the returned review with the agreed goal. An automatic edit of an unnecessary finding still creates review noise and does not count as success.
