📝 WalkthroughWalkthroughThe PR restores iOS Tailscale pairing through QR and numeric IP/port entry, rejects unsupported routes, and protects bearer forwarding with exact authorization. It updates pairing guidance and localization, adds regression coverage, and applies non-functional Swift interoperability and syntax updates to macOS Git code. ChangesTailscale pairing flow
macOS Git code modernization
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🔵 Low · up to The change restores numeric Tailscale pairing while rejecting unsupported destinations, but a storage failure can leave pairing appearing successful even though future reconnects fail, and two validation failures are missing from pairing-failure analytics. The PR is mergeable with explicit owner awareness and follow-up for these bounded reliability and observability issues. Sequence Diagram(s)sequenceDiagram

Full details: Description checkExplanation The description provides a clear summary, testing details, regression coverage, verification results, and merge guidance. It omits the template's Demo Video, Review Trigger, and Checklist sections, but the core information is complete. Full details: Linked Issues checkExplanation The changes satisfy Full details: Out of Scope Changes checkExplanation The CmuxGit changes are unrelated to the iOS Tailscale pairing objectives. They modify Git filesystem probing, continuation typing, parsing syntax, and naming without an explained dependency on the pairing fix. Full details: Docstring CoverageExplanation Docstring coverage is 36.36% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Analyzed 44 functions across 23 files. (3 skipped: 2 unsupported, 1 too large.) Full details: Cmux Swift Actor IsolationExplanation PASS. The production changes do not introduce a stated Swift 6 actor-isolation failure. Full details: Cmux Swift Blocking RuntimeExplanation PASS. The PR diff against its actual PR parent adds no semaphores, blocking waits, sleeps, delayed dispatch, timers, polling loops, main-queue synchronous dispatch, or manual locks. The changed Full details: Cmux Browser Automation Off-MainExplanation PASS: The custom check is not applicable. The PR diff changes 26 iOS pairing, localization, and CmuxGit paths. It does not change Full details: Cmux Expensive Synchronous LoadExplanation PASS — The PR does not add or move an expensive agent-history load. The changed production Swift contains no new Full details: Cmux Cache Substitution CorrectnessExplanation PASS: The PR does not replace a fresh authoritative read with a cached value in a persistence, history, undo, or snapshot path. The Git snapshot changes retain fresh Full details: Cmux No Hacky SleepsExplanation PASS. The PR diff against main changes only Swift source/tests and Full details: Cmux Algorithmic ComplexityExplanation PASS. The production diff adds no scan over workspaces, sessions, files, or other user-owned records. The new authorization filtering in Full details: Cmux Swift ConcurrencyExplanation PASS. The pull-request diff does not introduce or materially expand any prohibited legacy concurrency pattern. The only added concurrency-related source lines are explicit type annotations on two existing Full details: Cmux Swift `@Concurrent`Explanation PASS.

The changed pairing logic is in the existing SwiftPM targets Full details: Cmux Swiftpm LockfilesExplanation PASS: The effective PR diff from common ancestor f756735 to PR tip b9d5d15 contains no Package.swift, Package.resolved, .gitignore, workflow, or cmux.xcodeproj/project.pbxproj changes. No package lockfile content changed, and the inspected cmux-owned package .gitignore files do not ignore Package.resolved. Therefore, no SwiftPM lockfile rule failure was introduced. Full details: Cmux Swift LoggingExplanation PASS. The PR adds no Full details: Cmux User-Facing Error PrivacyExplanation The changed production messages contain pairing guidance only. They mention Tailscale because the product exposes an explicit “Tailscale Only” connection choice and these messages are scoped to the Tailscale pairing flow. “MagicDNS” identifies the unsupported host form and does not expose a raw provider error, credential, token, header, payload, or internal diagnostic. The retained “Iroh” text was already present in the old localization value and is not newly exposed by this diff. Added credentials and bearer values occur only in tests.

The changed SwiftUI views only update localized/default text in Full details: Cmux Architecture RethinkExplanation PASS: The PR introduces no architectural-rethink failure. The production changes use local immutable authorization values and route validation inside the existing Full details: Cmux Swift Auxiliary Window Close ShortcutsExplanation PASS: The PR does not add or materially change a standalone cmux-owned window. Its Swift UI changes update existing pairing view text only, and the pairing window controller is unchanged. The existing Full details: Cmux Source ArtifactsExplanation PASS. The PR-side diff contains 19 paths, all under source, test, or localization locations.
