Included review availability: Your plan provides up to 10 included reviews per hour; 2 remain after this review. 📝 WalkthroughWalkthroughAdded native Codex subagent hooks and a durable turn ledger. Codex ownership now controls completion notifications, runtime status, pending work, and session lifecycle. Tests cover nested ownership, child draining, exactly-once completion, and top-level stops. ChangesCodex turn lifecycle
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟠 High · up to This change is intended to make Codex completion notifications occur at the correct time, but the current implementation can still miss notifications, emit them prematurely, or stop tracking later sessions after malformed or stale state. These are high-impact correctness issues in the feature being fixed, so the PR is not ready to merge until they are resolved.

The Testing section also reports pending validation despite the implementation being present.

The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Analyzed 55 functions across 9 files. (1 skipped: 1 too large.) Full details: Cmux Swift Actor IsolationExplanation No Swift actor-isolation failure is introduced. The changed CLI target uses Swift 5.0 and has no default MainActor setting. The new Sendable declarations are value structs/enums with value fields. The mutable CodexTurnLedger class is not Sendable and is used by synchronous, file-locked transactions. The package changes extend existing Sendable value types with a Bool and initializer, without adding MainActor isolation, service protocols, or UI-bound stores. The added test file is also exempt by the check. Full details: Cmux Swift Blocking RuntimeExplanation PASS.

The new Resolution Move the new hook-store lookup and Codex ledger read/modify/write transaction into a non-main actor, detached repository, or other background cached path. Await only the small ownership/settlement decision in the hook handler. Alternatively, resolve the subagent target from an existing focused cache without loading the full hook store. Keep all ledger file locking and JSON parsing off the socket handler, and return to the interactive path only for the required socket/UI or process-launch work. Full details: Cmux Cache Substitution CorrectnessExplanation PASS. The PR does not introduce a cached or opportunistic replacement in a persistence, history, undo, or snapshot path. The removed Codex transcript-tail reads are replaced by native child-lifecycle events, which the PR documents as the lifecycle authority. Each ledger operation loads the JSON file under an exclusive lock and atomically persists the updated state; the coordinator holds no in-memory cache. The existing session-store lookup also remains an on-disk locked read. No TypeScript or JavaScript production change is present. Full details: Cmux No Hacky SleepsExplanation PASS: The PR introduces no covered hacky sleep or wall-clock synchronization.

The full diff from the main merge base changes Codex CLI, hook, persistence, wrapper, project wiring, and behavior-test files only. No added Swift line contains NSWindow, NSPanel, NSWindowController, WindowGroup, or close-shortcut routing. The deterministic lint also passes: scripts/lint_auxiliary_window_close_shortcuts.py reports 35 checked identifiers and no failures. Full details: Cmux Source ArtifactsExplanation PASS: The complete PR diff from merge base 91452a2 contains only Swift source, Swift tests, an Xcode project configuration, and the Codex wrapper script. No changed path matches the prohibited scratch or artifact directories, and no changed path has a log, screenshot, recording, archive, or build-artifact extension.

Inline comments:
In `@CLI/cmux.swift`:
- Around line 34866-34868: Remove the redundant
terminalActivePromptTurnIdsForStop constant and stop passing it to
recordPromptStop, relying on the method’s default empty
terminalActivePromptTurnIds value while preserving the existing call behavior.
- Around line 34740-34764: The Codex stop-hook path must fail closed when
ownership cannot be resolved. In the `if def.name == "codex",
!sessionId.isEmpty` handling around `codexStopDecision`, require a non-nil
ledger decision before proceeding; when `codexStopDecision` is unavailable,
suppress completion notification and return the empty response instead of
allowing `nil` to default through active-child or `shouldNotify` logic.
In `@CLI/CodexTurnLedger.swift`:
- Line 10: Add an explicit empty deinit to the CodexTurnLedger class to satisfy
the required_deinit lint rule, without changing its existing behavior.
- Around line 293-305: When a .promptSubmit starts a new turn, clear the
existing settledTurnIDs and notifiedTurnIDs entries for its turnKey before
processing completion events, including the "`@current`" fallback key. Preserve
duplicate detection within the current turn while allowing later turns without
IDs to notify normally.
- Around line 272-280: Update the .subagentStop branch in the turn ledger to
reconcile record.pendingTurns when stopChild leaves no active children, settling
the corresponding pending turn instead of returning .none. Route that settled
decision through the existing notification path so completion is delivered and
the pending entry is removed; preserve .none only when no turn is ready to
settle.
In `@CLI/CodexTurnLedgerPersistence.swift`:
- Around line 46-59: Update trim and its nested trimDictionary helper to evict
dictionary entries by recency rather than lexicographic key order, while always
retaining the active turn’s key and its children until completion. Preserve the
existing maximumTurnKeys limit for other entries so the current turn cannot be
removed while subagents remain active.
- Around line 123-131: Update CodexTurnLedgerPersistence.load() to return an
empty CodexTurnLedgerFile when decoding the existing file fails, allowing the
next locked write to replace corrupt contents instead of propagating the error.
Also add a custom Decodable init(from:) to CodexTurnLedgerFile so missing
records or surfaceOwners keys default to empty dictionaries via decodeIfPresent.
In `@CLI/CodexTurnLifecycleCoordinator.swift`:
- Around line 122-138: Update recordFeedLifecycle to map "SubagentStart" to the
start path and "SubagentStop" to the stop path explicitly; return .ignored for
every other eventName instead of treating it as a stop event.
In
`@Packages/macOS/CMUXAgentLaunch/Sources/CMUXAgentLaunch/CodexHookInjectionSchema.swift`:
- Around line 23-24: Add the superseded six-event schema to the recognized
entries in CodexHookInjectionSchema, preserving its exact event order,
subcommands, timeout values, and synchronous flags, including PreToolUse as the
third event. Keep the existing current schema entry unchanged so replay
sanitization can match and remove commands saved by either version.

Preserve the superseded current shape in recognized.
The existing six-event entry is a different schema. It expects PreToolUse as the third event and uses different event order and timeouts. AgentLaunchSanitizerCodexLaunch matches recognized entries in exact order and checks each event, subcommand, and timeout. Add the previous six-event shape so saved commands from the previous version remain removable during replay sanitization.
