-
Explanation
The description clearly explains the problem, implementation, preserved safeguards, and validation. It is mostly complete, but it omits the template's Changelog, Proof, and Checklist sections and uses "Validation" instead of "Testing."
Full details: Docstring Coverage
-
Explanation
No functions found in the changed files to evaluate docstring coverage. Skipping docstring coverage check. Docstring coverage is scoped to functions touched by this diff. Analyzed 0 functions across 0 files. (1 skipped: 1 unsupported.)
Full details: Cmux Cloud Persistent Session And Early Input
-
Explanation
PASS: The pull request changes only
scripts/gh-merge-green. The diff replaces a detached Git worktree withgit merge-tree --write-treeand targetedgit archivecalls, pluses freeze/vp diagnostics. It does not change Cloud terminal creation,cmux-tuitransport, manual renderers, PTY readiness, input routing, snapshots, auth, idempotency, revision fences, or leases. The custom check is therefore inapplicable.
Full details: Cmux Browser Automation Off-Main
-
Explanation
PASS: The pull request changes only
scripts/gh-merge-green. The diff adds nobrowser.*socket command, WebKit/AppKit access, worker-router routing, or browser policy test change. The rule applies toSources/TerminalController.swiftand the control-socket policy files, which are unchanged.
Full details: Cmux Expensive Synchronous Load
-
Explanation
PASS: The pull request changes only
scripts/gh-merge-green; the authoritative diff contains no Swift files or Swift code. Therefore it does not add or move an expensive synchronous agent-history load onto the main actor or an interactive path.
Full details: Cmux Cache Substitution Correctness
-
Explanation
The pull request changes only the CI shell helper
scripts/gh-merge-green. It does not change production Swift, TypeScript, or JavaScript code, and it does not substitute a cache for an authoritative read in a persistence, history, undo, or snapshot path.
Full details: Cmux No Hacky Sleeps
-
Explanation
PASS: The PR changes only
scripts/gh-merge-greenand introduces no fixed sleep, timer, polling loop, delayed dispatch, or wall-clock retry. The existingsleep 3loop remains unchanged in behavior; only its line number shifts. The new logic usesgit merge-tree,git archive, and direct checks.
Full details: Cmux Algorithmic Complexity
-
Explanation
PASS: The PR changes only
scripts/gh-merge-green. Its new collection work is linear: one pass over changed paths and one pass over Swift paths for existence checks. Thegit archivecommands use a fixed list of paths, and the new Python formatting joins are linear. The diff adds no nested scalable-collection scan, per-target rescan, hot-path repeated sort/filter, in-memory join, or unbenchmarked slower algorithm.
Full details: Cmux Swift Concurrency
-
Explanation
The pull request changes only
scripts/gh-merge-green(+27/-13). It changes Git archive and shell-check behavior, not cmux-owned Swift code. No added lines introduce Dispatch queues, Combine state, completion-handler APIs, or fire-and-forget Tasks.
Full details: Cmux Swift `@Concurrent`
-
Explanation
PASS — The authoritative pull-request diff changes only
scripts/gh-merge-green. It contains no.swiftfiles, Swift declarations, or Swift call sites. Therefore the@concurrentrule does not apply.
Full details: Cmux Swiftpm Lockfiles
-
Explanation
The PR changes only
scripts/gh-merge-green. It does not modify a SwiftPM package,Package.swift, anyPackage.resolved, an Xcode project package reference, a.gitignore, a workflow file, or dependency pins. The SwiftPM lockfile policy is therefore not applicable.
Full details: Cmux User-Facing Error Privacy
-
Explanation
PASS. The diff changes
scripts/gh-merge-green, an internal merge/CI helper documented for team members and CI operators, not a cmux app UI, product CLI, or product API path. Its added refusal and diagnostics report merge-tree materialization, Git paths,bun/vp, and commit references. The review rule permits provider and implementation details in internal CI and operator diagnostics. No changed text reaches cmux end users or exposes prohibited secret or personal data.
Full details: Cmux Full Internationalization
-
Explanation
The PR changes only the operational
scripts/gh-merge-greenhelper. The added refusal text and revisedvpdiagnostics are merge-check operator output, not Swift UI or web product copy. The diff adds no Swift localization keys, app catalogs, web messages, locale registry entries, metadata, or user-facing application data.
Full details: Cmux Swiftui State Layout
-
Explanation
PASS: The pull request changes only
scripts/gh-merge-green(a shell script). The diff contains no Swift, SwiftUI,ObservableObject,@Published,@Observable,GeometryReader, list-row, or render-time state changes. The SwiftUI state-layout rules are not applicable.
Full details: Cmux Architecture Rethink
-
Explanation
PASS: The pull request changes only
scripts/gh-merge-green(+27/-13). It does not modify Swift architecture, lifecycle ownership, or Swift state. The added logic uses Git archive/tree handling and Python formatting, not sleeps, polling, locks, observers, side channels, duplicate Swift entrypoints, or split UI ownership.
Full details: Cmux Swift Auxiliary Window Close Shortcuts
-
Explanation
The pull request changes only
scripts/gh-merge-green; the authoritative diff contains no Swift or SwiftUI source changes and adds no standalone cmux-owned window code. The auxiliary-window close-shortcut rule is therefore not applicable.
Full details: Cmux Source Artifacts
-
Explanation
The PR changes only the hand-written executable script
scripts/gh-merge-green. The diff adds runtime use of temporary directories and archives, but it adds no temporary folder, generated output, cache, log, screenshot, recording, dependency checkout, or other artifact path to source control. The changes are intentional CI/merge-check script logic.
Full details: Cmux No Test Or Debug Seam In Production Source
-
Explanation
PASS: The pull request changes only
scripts/gh-merge-green. The authoritative diff contains no Swift files and no files under a productionSources/path, so it cannot introduce a test or debug seam in production Swift source.

🩺 Stability & Availability | 🟠 Major | 🏗️ Heavy lift
Preserve repository access for the Swift checker.
When a PR changes a Swift file, this archive creates $merged without Git metadata. The base branch’s check-no-godfiles.sh runs git -C "$root" rev-parse --show-toplevel and exits if that command fails. The guarded merge then refuses even a clean Swift change. Give the checker access to $repo_dir while it measures the archived merged files. (raw.githubusercontent.com)

⚠️ Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.Materialize every tracked Swift file used by the guard.
If a PR adds an
export-ignoreattribute for an unchanged Swift file,git archiveomits that file from$merged. The changed Swift file can remain present, so the path check at Line 932 passes. Once the separately reported Git-access failure is fixed, the god-file checker can measure an incomplete module and miss an over-budget type. Compare the extracted Swift files with the merged tree, or materialize their raw blobs without archive attributes. Git documents thatgit archiveappliesexport-ignore. (git-scm.com)

Merge receipt for |
…cx-q1lnl) 134 main commits since the last sync (3e7ed5a). Full rename detection (merge.renameLimit=100000). manaflow-ai#21310 (0d5316d, export npm_config_prefix) is now on main; it is a superset of feat's manaflow-ai#21311 copy, so the resume workflows keep one version (main's). No Swift, Rust, Go or package manifest change survives the merge (daemon/remote/go.mod unchanged). Conflict choices: - 209 modify/delete and 1 rename/delete in the legacy app, legacy CLI, cmuxTests, legacy Swift packages and Resources/Localizable.xcstrings: kept deleted. - cmux.xcodeproj/project.pbxproj, cmux.xcworkspace/contents.xcworkspacedata, docs/cli-contract.md, tests/test-execution.toml: feat-cmux-next's side. - ci-macos.yml, seed-derived-data.yml, restore-app-host-test-product.sh, package-test-lane.sh (CmuxTextActions), tests/test_ci_change_areas.py (app-host admission block): feat's side; main's rsync --no-times edits are for CmuxAgentJournal framework staging that feat deleted. Main's new merge-gate change-area test merged in. - scripts/ci/compile-app-host-test-product.sh: main's logic (the legacy cmux target builds without the compilation cache on every Xcode); the test (test_ci_test_compilation_cache_seed.sh) keeps feat's one-scheme checks with main's every-Xcode loop. - nightly.yml and tests/test_nightly_universal_build.sh: feat's side (feat already had manaflow-ai#21761's empty DerivedData start via manaflow-ai#21762, plus the nightly-next build-state prepare and its no-replay check; manaflow-ai#21544's promotion change was already on feat via manaflow-ai#21533). Feat's WRITER gate, live HOLD read, recovery guard, legacy-identity split, Mach-O floor, macOS 15 launch job and bash 3.2 parse hardening kept. - scripts/gh-merge-green: main's version (multiple freeze tokens manaflow-ai#21584, merge-tree merged head manaflow-ai#21576, missing Swift path refusal manaflow-ai#21560, risk evidence manaflow-ai#21692) plus feat's "cmux-next Swift canary" required check, freeze expiry and owner/pr/head metadata, and the canonical merged path. - scripts/install-cmux-tui-client.sh: union of the header comments (main's total download budget manaflow-ai#16305 and feat's attestation retry text). - web/data/cmux-shortcuts.ts: feat's generated table. - web/services/vms/workflows.ts: feat's doc comment on requireUserVm. - Run API: feat's version (manaflow-ai#21337, open lanes manaflow-ai#21634/manaflow-ai#21305 build on it). web/services/runs/*, web/app/api/runs/*, web/db/schema.ts run tables: feat's side.

Summary
The guarded merge helper's merged-head verification could stall or time out when its checkout was a
blob:nonepartial clone. It tried to materialize a full worktree solely to run the Swift god-file and webvpchecks.This change computes the exact merged tree with
git merge-tree --write-tree, then archives only the Swift/web paths those checks inspect. Merge-conflict detection and the existing guard checks remain fail-closed, while unrelated historical blobs are no longer fetched.Validation

@codesmith-botwith what you need.Summary by cubic
Fixes guarded merge checks timing out on
blob:nonepartial clones. The helper previously materialized a full worktree to run the Swift god-file and webvpchecks; it now computes the merged tree withgit merge-tree --write-treeand archives only the paths those checks inspect, so unrelated historical blobs are no longer fetched. The base tree is archived separately for the red-basevpcomparison (now with locked dependencies installed), since the merged archive is not a worktree. Merge-conflict detection and existing guard checks remain fail-closed, and merges are refused if the checked tree objects cannot be materialized. Makes refusal diagnostics portable on macOS by switching frompastetopython3for joining lists.Written for commit 07e82b4. Summary will update on new commits.
