Summary

scripts/ci/review_receipt.py is the review gate that gh-merge-green uses, and cmuxterm-hq agent-guards keeps a pinned copy of it. It filed an independent SHIP as a lane's carried receipt whenever "carry/carries/carried/carrying" appeared anywhere on the first line.

On cmux#27632 the review's first line was "Review (independent review subagent): SHIP at feae730… the warning carries the whole finding." The gate read it as carried. A carried SHIP stands only behind an independent SHIP, so the gate answered "no SHIP review receipt on this head".

The lanes write the carried marker in the reviewer label: Review (<reviewer>; carried): SHIP at <head> (#26809, #26988, #27008, #27189). CARRIED now matches the word only there, or "carried from" / "carried over" anywhere on the first line. Any other "carries" in the verdict text no longer counts.

skills/cmux-review/SKILL.md now says how to write a receipt and a carried receipt, and which words to avoid in a real review's first line.

Same rule in cmuxterm-hq: next_autoland (cmuxterm-hq#5209). The agent-guards copy is pinned again to this PR's merge commit after it lands. cmuxterm-hq#5213 restored the old pin, because #5209 had edited the copy before this change.

Testing

• python3 tests/test_review_receipt.py: 46 OK. The new test_a_ship_whose_text_says_carries_is_a_review fails on the base:
  • The ci(cmux-next): a PR's sidebar sweep warns on base commits; its own commits stay errors #27632 line passes alone.
  • The four real carried forms, carries in the label and "carried from/over" are carried and never pass alone.
  • "carries over" and "carried" in other prose are not carried.
• python3 tests/test_gh_merge_green.py: OK.
• python3 scripts/verify-local.py: 16/17 selected checks passed.

Summary by cubic

Fixes the review receipt gate so a carried SHIP is recognized only when "carried" appears in the reviewer label or as "carried from"/"carried over" on the first line, not when "carries" appears elsewhere in the verdict text.

scripts/ci/review_receipt.py previously treated any first line containing "carry/carries/carried/carrying" as a carried receipt. A review on cmux#27632 whose text included "the warning carries the whole finding" was refused as carried with no independent SHIP behind it. The regex now matches the marker only in the reviewer label (e.g. Review (codex; carried): SHIP at <head>) or as "carried from"/"carried over".

• Updates skills/cmux-review/SKILL.md with how to write a receipt and a carried receipt.
• Adds tests for the ci(cmux-next): a PR's sidebar sweep warns on base commits; its own commits stay errors #27632 line, real carried forms, and non-carried wording in prose.

^{Written for commit b319502. Summary will update on new commits.}

Summary by CodeRabbit

• Bug Fixes
  • Carried review receipts are identified only by carry wording in the reviewer label or an opening line that explicitly says “carried from” or “carried over.” Mentions of carrying elsewhere in the review no longer count as carry markers.
• Documentation
  • Review guidance clarifies that a SHIP applies only to its named commit. Carrying it across a base merge requires a carried label, and it counts only when the newest independent verdict on the PR is also a SHIP.

Walkthrough

The carried-receipt matcher now recognizes carry wording in reviewer labels or explicit “carried from” and “carried over” first-line text. Review instructions and tests cover these rules and distinguish them from ordinary verdict prose.

Changes: Review receipt classification

Layer / File(s)	Summary
Carried receipt rules skills/cmux-review/SKILL.md, scripts/ci/review_receipt.py, tests/test_review_receipt.py	The review instructions define receipt formatting and carried SHIP conditions. The matcher recognizes the specified carry markers, and tests check carried and ordinary SHIPs.

The classification change has a narrow edge case: a receipt mentioning multiple commits can approve a commit other than its stated SHIP target. Tightening SHA binding is a bounded follow-up; no counterpart deployment mismatch was established.

(1 skipped: 1 unsupported.)

Full details: Cmux Cloud Persistent Session And Early Input

Explanation

PASS: The pull request changes only review-receipt classification, review documentation, and review-receipt tests. It does not change Cloud terminal creation, cmux-tui transport, manual renderer admission, input ownership, authentication, idempotency, revision, or lease handling. The cloud persistent-session failure conditions are therefore not applicable.

Full details: Cmux Swift Blocking Runtime

Explanation

The pull request changes only Python and Markdown files: scripts/ci/review_receipt.py, skills/cmux-review/SKILL.md, and tests/test_review_receipt.py. The reviewed range contains no Swift files and introduces no Swift blocking or timing-based synchronization.

Full details: Cmux Browser Automation Off-Main

Explanation

PASS: The pull request changes only scripts/ci/review_receipt.py, skills/cmux-review/SKILL.md, and tests/test_review_receipt.py. The diff contains no browser socket automation commands, WebKit/AppKit access, worker-router changes, or ControlCommandExecutionPolicyTests changes. The browser automation rule is therefore not applicable, and no off-main behavior is introduced.

Full details: Cmux Cache Substitution Correctness

Explanation

PASS: The pull request changes only Python (scripts/ci/review_receipt.py, tests/test_review_receipt.py) and Markdown (skills/cmux-review/SKILL.md). It introduces no production Swift, TypeScript, or JavaScript change, so the cache-substitution failure condition does not apply.

Full details: Cmux No Hacky Sleeps

Explanation

PASS. The pull request changes a Python receipt-classification regex, documentation, and tests. The diff introduces no sleep, timer, polling loop, fixed backoff, delayed dispatch, or wall-clock wait. No runtime synchronization behavior is added or worsened.

Full details: Cmux Algorithmic Complexity

Explanation

PASS. The pull request changes a compiled regex in scripts/ci/review_receipt.py and adds documentation/tests. It introduces no nested collection scan, per-target rescan, sorting/filtering hot path, join, or slower scalable algorithm. The existing review/comment inputs are explicitly bounded to 30 reviews and 40 comments.

Full details: Cmux Swift Concurrency

Explanation

PASS: The pull request changes only Python, Markdown, and Python test files. It introduces no cmux-owned Swift code and therefore does not introduce or expand any listed legacy Swift concurrency pattern.

Full details: Cmux Swift `@Concurrent`

Explanation

The pull request changes only Python and Markdown files (scripts/ci/review_receipt.py, tests/test_review_receipt.py, and skills/cmux-review/SKILL.md). It contains no Swift changes, so the Swift @concurrent check is not applicable.

Full details: Cmux Swift Package Boundaries

Explanation

PASS: The pull-request diff changes only Python, Markdown, and Python test files (scripts/ci/review_receipt.py, skills/cmux-review/SKILL.md, and tests/test_review_receipt.py). It contains no production Swift changes, so the Swift package boundary rule does not apply.

Full details: Cmux Swiftpm Lockfiles

Explanation

PASS. The reviewed diff changes only scripts/ci/review_receipt.py, skills/cmux-review/SKILL.md, and tests/test_review_receipt.py. It contains no SwiftPM package, Xcode project, .gitignore, workflow, dependency, or Package.resolved changes. Therefore the SwiftPM lockfile failure conditions do not apply.

Full details: Cmux Swift Logging

Explanation

PASS. The pull request changes only scripts/ci/review_receipt.py, skills/cmux-review/SKILL.md, and tests/test_review_receipt.py. It adds no Swift code or production logging. The Swift logging rule is therefore not applicable.

Full details: Cmux User-Facing Error Privacy

Explanation

PASS. The diff changes an internal CI merge gate, its tests, and developer review documentation. scripts/gh-merge-green invokes scripts/ci/review_receipt.py for merge gating and forwards its stderr to the merge operator; this is an internal CI/operator surface, which the rule explicitly allows. The changes add no cmux app UI, product CLI, or product API error path, and expose no secrets, credentials, personal data, or sensitive payloads.

Full details: Cmux Full Internationalization

Explanation

PASS. The PR changes only the Python review-receipt gate, its tests, and operational review documentation. It introduces no Swift UI text, app catalog or Info.plist entries, web UI/API copy, locale data, or web/messages changes. The changed receipt words are protocol tokens and developer/CI content, which the rule allows.

Full details: Cmux Swift Auxiliary Window Close Shortcuts

Explanation

The pull request changes only scripts/ci/review_receipt.py, skills/cmux-review/SKILL.md, and tests/test_review_receipt.py. It contains no Swift or standalone cmux-owned window changes, so the auxiliary-window close-shortcut rule is not applicable.

Full details: Cmux Source Artifacts

Explanation

The PR changes only scripts/ci/review_receipt.py, tests/test_review_receipt.py, and skills/cmux-review/SKILL.md. These are intentional source, test, and documentation files. The diff adds no logs, screenshots, recordings, temporary directories, caches, build output, dependency checkouts, or broad artifact directories.

Match the SHIP sha that follows the verdict word.

40-42: Minor · Functional Correctness · Quick win

Match the SHIP sha that follows the verdict word.

names_head accepts any full 40-character token in the first 600 characters of a receipt line. A first line such as Review (<reviewer>): SHIP at <old sha>; compared with <new sha> therefore counts as an independent SHIP for <new sha>. The skill text says a SHIP counts only for the exact head it names. Parse the sha that follows SHIP at, or refuse a SHIP line that names more than one full sha.

Update the receipt validation around names_head so a SHIP counts only for the
full SHA immediately following “SHIP at”; reject a SHIP line if it names
multiple full SHAs instead of matching any SHA in the first 600 characters. Keep
the documented exact-head requirement consistent with this behavior.

Review (subagent, correctness first): SHIP at b319502

An independent review subagent of the cmux-next Performance Lead agent reviewed this in two rounds.

• Safety. All 7 real carried receipts on cmux-next swift test: main-thread-heavy suites in their own processes, the broad pass sharded, SIGPIPE caught as in the app #26809, feat(inspector): summarize agent work in Session Info #26988, Open workflow agent transcripts beside their chat #27008, fix(agent-pane): keep Preview tab-row tools visible #27189, fix(next): remove plates behind trailing header and output controls #27130 and feat(next): add Labs workflow side tab #27000 put the word in the label, and they are still carried.
• Callers. Every caller pairs CARRIED with RECEIPT.match on the same first line.
• Edge cases. Markdown before the label, upper case and carry-over are still carried. Nested parentheses give no SHIP at all, which fails closed.
• Tests. tests/test_review_receipt.py: 46 OK. The new test fails on the base. tests/test_gh_merge_green.py: 169 OK.
• Delta since eead932. Only the docstring, a comment and SKILL.md changed. The comment now says hq next_autoland has the same rule, which is true since cmuxterm-hq#5214 merged as c111dadf.
• Nit. Docstring line 24 is long.
• Accepted narrowing. A carry claim written outside the label without "carried from/over" now counts as a SHIP. No real receipt uses that form.

cmux status _{(one comment, edited in place; each line is updated by the job that owns it)}

Merge receipt for b319502166: every check was green at merge (10 verified; 17 skipped by policy). Full suite runs on main after merge.

[lawrencecchen]

Merge note. I merged this PR with gh api -X PUT repos/manaflow-ai/cmux/pulls/27725/merge -f merge_method=squash -f sha=b319502166cc1cf9e65217a7d3dfbe1e337be646. Merge commit: d8a0c78.

Why I used the API:

1. gh-merge-green ran first. Its gate passed: full gate, ci-status green on the exact head.
2. Its final gh pr merge step then refused with "the base branch policy prohibits the merge".
3. CLAUDE.md names the API merge, pinned to the exact head sha, as the path for that message.

The API merge succeeded at once, so no rule actually held the PR. I did not use --override or --admin. The coordinator reviewed this path and accepted it.
