Full details: Description checkExplanation The description provides a detailed summary, rationale, testing coverage, static-check results, and clear scope limitations. It omits the demo video, review-trigger block, and checklist from the template, but the core information is complete and relevant. Full details: Docstring CoverageExplanation Docstring coverage is 4.17% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Analyzed 24 functions across 5 files. (1 skipped: 1 unsupported.) Full details: Cmux Swift Actor IsolationExplanation No explicit actor-isolation failure is introduced. The new aggregation code extends the existing Full details: Cmux Swift Blocking RuntimeExplanation PASS: The PR adds no blocking or timing-based synchronization to production Swift. The production diff only adds synchronous lifecycle aggregation, direct lookups, and Escape forwarding. Added tests use immediate assertions and AppKit setup; they add no semaphore, wait, sleep, delayed dispatch, timer, polling, main-queue sync, or manual lock. The rule explicitly allows deterministic test-only scaffolding. Full details: Cmux Browser Automation Off-MainExplanation PASS: The pull request changes only agent lifecycle, TerminalPanel TextBox Escape handling, project wiring, and related tests. The rule’s target files, Full details: Cmux Expensive Synchronous LoadExplanation PASS: The PR adds no synchronous agent-history load. Full details: Cmux Cache Substitution CorrectnessExplanation PASS: The production diff does not replace a fresh authoritative read in a persistence, history, undo, or snapshot path. The existing Workspace hibernation method keeps the same Full details: Cmux No Hacky SleepsExplanation PASS. The pull request changes only Swift source/tests and Xcode project metadata. The usable diff from main introduces no TypeScript, JavaScript, shell, or non-Swift build/runtime script changes. The added lines contain no fixed sleeps, timers, delayed dispatch, polling, or wall-clock waits. Swift timing is explicitly outside this check's scope. Full details: Cmux Algorithmic ComplexityExplanation PASS. The new TextBox Escape path checks the fixed 19-key Full details: Cmux Swift ConcurrencyExplanation PASS: The PR adds only synchronous lifecycle aggregation, bounded set lookup, and direct Escape handling in cmux-owned production code. Added Swift lines contain no DispatchQueue, DispatchGroup, Task, async/await, completion-handler, Combine, publisher, or cancellable patterns. Full details: Cmux Swift `@Concurrent`Explanation No Swift concurrency rule violation was introduced. The diff adds only synchronous aggregation methods and synchronous TextBox Escape handling. The changed TerminalPanel and test code are explicitly Full details: Cmux Swift Package BoundariesExplanation The PR adds independently testable domain logic to the app target. Resolution Extract Full details: Cmux Swiftpm LockfilesExplanation PASS: The PR changes no Full details: Cmux Swift LoggingExplanation PASS — The two-commit diff adds lifecycle aggregation, Escape forwarding, project wiring, and tests, but no Full details: Cmux User-Facing Error PrivacyExplanation The production diff adds lifecycle aggregation and PTY Escape routing only. It adds no user-facing errors, alerts, command output, API error bodies, or recovery copy. The added strings are lifecycle keys and developer comments; the diagnostic assertions are in tests, which the rule allows. No prohibited provider, credential, token, header, payload, or upstream error text is introduced into user-visible text. Full details: Cmux Full InternationalizationExplanation PASS. The production diff adds lifecycle aggregation and Escape authorization logic, but it adds no user-facing Swift text. The new literals ( Full details: Cmux Swiftui State LayoutExplanation PASS. The PR does not introduce a covered SwiftUI state or layout pattern. The diff adds lifecycle aggregation, Dock/workspace methods, AppKit TextBox Escape handling, and tests. Full details: Cmux Architecture RethinkExplanation PASS. The diff adds a small Escape authorization fix with clear ownership. Full details: Cmux Swift Auxiliary Window Close ShortcutsExplanation PASS. The PR adds lifecycle and TextBox Escape logic, but it does not add or materially change a user-visible auxiliary window, panel, controller, Window, or WindowGroup. The new test uses an existing Full details: Cmux Source ArtifactsExplanation PASS: The PR diff contains only five Swift source files, one new Swift test source, and the Xcode project configuration. The new test is wired into the test target, and the project diff adds only source-file references. No logs, screenshots, recordings, caches, temp or broad artifact directories, dependency checkouts, build output, or copied binary artifacts appear in the changed paths or added content. Full details: Cmux No Test Or Debug Seam In Production SourceExplanation No test or debug seam was added to production Swift source. The PR diff adds no DEBUG/TESTING guard, visibility widening, or test/debug-named member. The new private Full details: Cmux No Ambient Global StateExplanation PASS: The production diff adds no file-scope API function, mutable global, stub global-state holder, or singleton. The new aggregation methods are static methods on the existing state enum

Static integration review note for current head f75a3c5:\n\n- AppKit delivers key-down events to the first responder, and NSResponder's default keyDown implementation forwards an unhandled event through the responder chain. The TextBox keeps ownership of Escape and calls the existing TerminalPanel action, which avoids duplicate responder delivery.\n- The implementation sends the existing named-key protocol token to the terminal surface. It does not synthesize or reinject an NSEvent. This preserves the terminal input path while the existing focus and two-Escape behavior runs.\n- Escape authorization iterates the fixed built-in allowlist and performs direct dictionary lookups. It does not copy or scan the unbounded custom lifecycle map. Manual and custom Vault keys remain excluded.\n- TerminalPanel, Workspace, and DockSplitStore calls remain synchronous on the main actor. No new task, timer, or cross-actor access was added.\n\nReferences:\n- NSResponder keyDown\n- NSEvent keyEvent\n- Cocoa Handling Key Events\n- Swift concurrency and the main actor\n\nStatic checks passed: project normalization, test-target wiring, test determinism, Swift parse, and diff checks. Local Xcode tests and builds were intentionally not run for this static-only triage. |

Keep this integration suite on XCTest.
Convert TextBoxEscapePassthroughTests to an XCTestCase. Replace @Suite, @Test, #require, and #expect with the corresponding XCTest APIs. Preserve serialized execution because the suite mutates NSApp and shared application state.
Based on learnings, “new test methods should remain using XCTest” because cmuxTests integration suites depend on the XCTest lifecycle.
