Verification

End-to-end dogfooded on a freshly-installed signed nightly DMG (commit 791318f5) on a clean cloud macOS 15.6.1 VM:

• cmux ssh runner@localhost daemon transitions disconnected → connecting → connected/ready in 3s
• echo PR4135-NIGHTLY-VIDEO-$$ ran on the remote bash, $$ expanded to remote PID — keystrokes reach the remote shell
• 12 workspaces created, selected workspace reordered to bottom remains visible
• All four file preview types render under both background-opacity = 1.0 and 0.85 Ghostty configs
• Sidebar resize drag works
• cmux vm error paths return actionable guidance
• Auto-update path byte-identical to v0.64.5 (no changes to Info.plist / Sources/Update / entitlements / Sparkle framework)

Test plan

• Cloud-mac dogfood on signed nightly DMG
• CircleCI macos-unit-tests green on main
• Release workflow signs and notarizes cmux-macos.dmg from the v0.64.6 tag

❌ Failed checks (1 error)

Check name	Status	Explanation	Resolution
Cmux Swiftui State Layout	❌ Error	New ObservableObject with @Published in SidebarState.swift violates swiftui-state-layout.md. Should use @Observable macro instead for new cmux-owned SwiftUI state.	Replace final class SidebarState: ObservableObject with @Observable macro. Use value snapshots in views instead of @EnvironmentObject store references.

✅ Passed checks (15 passed)

Check name	Status	Explanation
Title check	✅ Passed	The PR title 'Release v0.64.6' directly and clearly summarizes the main change—a version bump release. It is concise and specific enough for teammates scanning history to understand this is a release commit.
Description check	✅ Passed	The PR description includes a comprehensive Summary section with Added/Changed/Fixed items and contributors list, detailed Verification section with specific testing steps, and Test plan. However, it does not include a Demo Video section or Review Trigger block from the template, though these are less critical for a release PR.
Docstring Coverage	✅ Passed	No functions found in the changed files to evaluate docstring coverage. Skipping docstring coverage check.
Linked Issues check	✅ Passed	Check skipped because no linked issues were found for this pull request.
Out of Scope Changes check	✅ Passed	Check skipped because no linked issues were found for this pull request.

Cmux Swift Blocking Runtime	✅ Passed	No blocking runtime patterns found in the Swift code. Searched all 504 Swift files for blocking synchronization patterns with zero matches.
Cmux No Hacky Sleeps	✅ Passed	PR modifies only documentation, build config version numbers, and static changelog metadata. No production runtime code changes in TypeScript, JavaScript, shell, or build scripts. Rule not applicable.
Cmux Swift Concurrency	✅ Passed	Initial v0.64.6 import. Legacy patterns are existing code from v0.64.6, not newly introduced. Test DispatchQueue patterns are allowed per rules.
Cmux Swift @Concurrent	✅ Passed	All Swift additions comply with @concurrent rules: no nonisolated async without @concurrent, no @concurrent on sync functions, no isolation conflicts.
Cmux Swift File And Package Boundaries	✅ Passed	CommandPaletteSettingsToggle.swift (686 lines) has single responsibility, under 800-line limit. No mixed concerns. Small focused new files. ContentView within budget.
Cmux Swift Logging	✅ Passed	No Swift logging violations found. Print statements in CLI/cmux.swift for user-facing command output are explicitly allowed per swift-logging.md rules.
Cmux User-Facing Error Privacy	✅ Passed	Error messages comply with privacy rules: no vendor/provider names exposed, credentials/tokens hidden, internal exceptions sanitized before display, details contain only safe diagnostics.
Cmux Architecture Rethink	✅ Passed	PR contains version bump and changelog updates. Examined Swift files show clean architecture: no timing repairs, sleeps, locks, observers, or duplicate entrypoint wiring patterns.
Cmux Swift Auxiliary Window Close Shortcuts	✅ Passed	No Swift changes introduce new NSWindow/NSPanel/NSWindowController/Window/WindowGroup code. Lint script passes. Changes are bug fixes and visual updates only.

Greptile Summary

This is a hotfix release PR bumping cmux from v0.64.5 to v0.64.6, with no Swift source or TypeScript logic changes — only metadata and documentation updates.

• CHANGELOG.md adds the v0.64.6 release section with accurate dates, contributor credits, and PR/commit links for all five fixes.
• GhosttyTabs.xcodeproj/project.pbxproj increments CURRENT_PROJECT_VERSION from 85 → 86 and MARKETING_VERSION from 0.64.5 → 0.64.6 across all 8 build configurations consistently (App, AppUITests, AppTests, and DockTilePlugin — Debug and Release each).
• changelog-media.ts adds four feature-highlight cards for 0.64.6 on the web docs changelog page; no hero image is attached, which is appropriate for a patch/hotfix release.

Confidence Score: 5/5

Safe to merge — all three changed files are documentation and build metadata with no production logic.

All 8 Xcode build configurations are updated consistently from build 85/0.64.5 to 86/0.64.6; the changelog and web docs accurately reflect the changes shipped in this release. No Swift source, runtime, or TypeScript logic is touched.

No files require special attention.
