Problem

A fresh iOS launch waited for the per-user paired-Mac backup refresh before dialing the cached IROH route. A slow backup response therefore delayed the first connection and could miss the workspace-list launch budget.

Fix

Startup now starts the backup refresh in parallel with the cached local route dial. It waits for that refresh only when the local attempt fails and a refreshed second attempt is needed. Manual and recovery reconnects retain the freshness-first behavior.

Validation

  • The focused regression hangs on the pre-fix commit when backup refresh is blocked, proving the old ordering.
  • The same regression passes on the fix commit while the IROH route connects before backup refresh completes.
  • swift test --package-path Packages/iOS/CmuxMobileShell --filter StartupRecoveryReadinessTests passes all 7 tests.
  • python3 scripts/verify-local.py --only swift-syntax --swift-changed origin/main passes.

Changelog

Fixed startup connection ordering so cached IROH connections begin without waiting for backup hydration.

Summary by cubic

Startup now dials a cached, device-local IROH route in parallel with the per-user backup refresh, and the v2 workspace.list response embeds authenticated host status, so a slow backup server and one relay round trip no longer delay the first connection.

Cached display state

  • The last complete workspace list persists per account/team and renders as display-only rows until the live connection establishes; snapshots carry no credentials or terminal output.
  • Snapshots clear on pairing deletion, explicit deletion, and a live empty list; demo workspace and foreground state survive reconciliation, explicit deletion wins races against snapshot restore, and a stored Mac is retried after auth restore when only a demo row remains cached.
  • Snapshot persistence, restore, and pruning run off the main actor with bounded storage, and v2 runtime ownership survives auth restore and soak.
  • Cached v2 state warms from the persisted account/team pair before auth bootstrap: it renders the cached directory and starts IROH but cannot authorize any control-plane request, scope is revalidated after restore, and endpoint warmup is retried within a bounded timeout.
  • Combined host status in the v2 response is validated against the expected installation identity before reuse; older Macs that omit the field fall back to the separate host-status request.
  • Hidden-Mac markers match snapshot keys by canonical device identity so legacy untagged markers restore their cached rows, and reconnect reuse picks the active Mac from stored pairing status including hidden Macs.

Release gate and compile repair

  • --restore-pairing replays the saved-pairing startup; --real-usage runs three real Codex sessions with foreground/background cycles, video evidence, and terminals kept open for verification, and the relay-rollover probe runs past the real 30-minute credential lifetime.
  • The release gate skips the optional Ghostty Zig helper so an unrelated network fetch can't fail a transport verdict; cached rows register at the UIKit visibility callback and keep their appearance timestamps until the live row is selectable, the workspace list must appear within 2.5 seconds of launch, app foreground readiness is stamped at scene activation, and the developer launch flow no longer auto-opens a workspace before the probe registers.
  • The attach minter separates CLI stdout from stderr so harmless startup diagnostics can't fail a valid ticket response.
  • The merged-main compile repair extracts the VM-wait poll policy, drives hook-state recovery tests through the real bundled cmux binary, and fixes a few mutating-assertion and controller-container tests.

Written for commit 2f574d6. Summary will update on new commits.

Summary by CodeRabbit

  • Bug Fixes
    • Startup reconnects can begin connecting to a paired Mac using a cached route while a backup refresh runs in the background.
    • Snapshot loading waits for a deferred backup refresh, so refreshed pairing data is available before the snapshot loads.
    • Reconnect route selection includes hidden paired Macs and identifies the active Mac from stored pairing status.
    • Reconnects still await backup refresh immediately when background refresh is unavailable.

📝 Walkthrough

Walkthrough

When backup refresh is enabled and the store supports it, hydrated reconnects start refresh in a background task. Reconnect can attempt a cached active-Mac route while refresh runs. It then uses the loaded paired-Mac snapshot and awaits deferred refresh before loading the reconnect snapshot.

Changes

Startup reconnect

Layer / File(s) Summary
Defer refresh and attempt the cached route
Packages/iOS/CmuxMobileShell/Sources/CmuxMobileShell/MobileShellComposite.swift
Qualifying hydrated reconnects start backup refresh in a background task. The flow can attempt a cached active-Mac route before loading the full pairing snapshot. After loading, it awaits the dial and returns connected if the dial succeeded. Route selection uses storedPairedMacsIncludingHidden and the row marked isActive. The refresh-snapshot loader awaits deferred refresh before loading the snapshot.
Test reconnect during blocked refresh
Packages/iOS/CmuxMobileShell/Tests/CmuxMobileShellTests/DelayedTeamPairedMacStore.swift, Packages/iOS/CmuxMobileShell/Tests/CmuxMobileShellTests/StartupRecoveryReadinessTests.swift
The delayed store can block refresh and signal when it starts and finishes. A startup recovery test checks that reconnect attempts an Iroh route before the blocked refresh is released.

Merge Risk: 🟡 Moderate · up to 12ef2

A launch with an empty local store can miss Macs available in backup, so the startup path should be fixed before merging. A team switch can also restore a stale pairing row that reappears when switching back.

Full details: Docstring Coverage

Explanation

Full details: Cmux Cache Substitution Correctness

Explanation

The reconnect snapshot path replaces the fresh activeMac/loadAll reads from the base revision with storedPairedMacsIncludingHidden at MobileShellComposite.swift:3389-3395. The code does await loadPairedMacs(), which provides a cold-cache read, but the cache has only scope metadata and load-generation coordination. It has no freshness check or event-driven invalidation for later store changes. The new deferred refreshFromBackup runs in parallel at lines 3291-3297, while the cache is consumed later, so the snapshot can precede backup merges or pending-delete replay. The call-site comments document a performance rationale, not why stale pairing identity or routes are safe. This is a non-transient pairing snapshot consumer, so the stale-cache condition is unhandled.

Resolution

Keep the cached active-row dial separate from authoritative candidate selection. Before using the pairing snapshot for fallback, await the deferred backup refresh and perform a fresh scoped store read, or reload loadPairedMacs(forceRefresh: true) after the refresh and verify that the cache generation matches that read. Add event-driven cache invalidation or a source-generation/freshness token for every local mutation and backup merge. Preserve the cold-cache failure path so an unhydrated or failed load falls back to the authoritative read rather than treating an empty cache as no pairings.

Full details: Cmux Swift Concurrency

Explanation

The production diff adds unstructured startup tasks with lifetimes that can outlive the reconnect operation. deferredBackupRefresh is awaited only when a cached attempt needs a refreshed fallback; a successful cached connection or an interruption returns while the refresh task continues without a retained lifecycle owner or cancellation. cachedActiveDialTask is also a local unstructured task and can outlive the parent when raceAgainstDeadline cancels its operation; that helper cancels the outer operation task, not these nested tasks. The added XCTest continuations and test Task are allowed test-only synchronization. No new Dispatch, Combine, or completion-handler pattern is present.

Resolution

Use structured child-task management, or store these tasks in explicit lifecycle-managed state. Tie cancellation to reconnect supersession, deadline cancellation, sign-out, team changes, and deinitialization, and await or cancel-and-drain every child on all return paths. Keep generation and scope guards so a refresh or dial cannot continue to mutate or claim state after its startup operation is no longer current.

Full details: Cmux Architecture Rethink

Explanation

The production diff adds a timing-based repair path. await Task.yield() is used at MobileShellComposite.swift:3356 to make the cached activeMac task start before loadPairedMacs() begins its SQLite read. This is scheduler-dependent ordering, not a data or lifecycle invariant. The cached task and the later candidate loop also provide separate startup dial paths, so route selection remains split while both paths can update connection state. The pairing store snapshot should be the single source of truth, and one reconnect coordinator should own the startup transition.

Resolution

Remove the production Task.yield() ordering dependency. Introduce one lifecycle-owned startup restore coordinator or pairing-store API that returns a coherent scoped snapshot, including the active row and all rows. Start the cached dial from that snapshot through the existing shared dial action. Await the refresh only for an explicit fallback transition, and cancel or invalidate that work on scope change, sign-out, and reconnect supersession. The first migration cut should replace the separate activeMac task plus loadPairedMacs() race with that single snapshot-and-dial path, then add tests for empty stores and scope changes.

Bound both startup waits and release the blocked refresh on failure.

If the refresh never starts, waitUntilBackupRefreshStarted() has no completion path. If reconnect waits for the blocked refresh, reconnect.value can wait until the reconnect deadline before failing, and the test cannot reach releaseBackupRefresh(). Use deadline-bounded races for both waits. On either timeout, release the refresh before awaiting reconnect or abandoned-task cleanup. This keeps the success path signal-based and bounds only the failure path.

Review subagent on 70bda043385360fbbdf4749f580fa861bfca2318 merged with current main. Holding this one: two launch-path regressions, both uncovered by any test.

The idea is right and the scoping is right. hydratePairedMacs: true has exactly one production call site (CMUXMobileRootView.swift:1156, launch and sign-in), and manual retry, connection recovery and team change all keep the blocking freshness-first order at :3299. The relaunched-on-a-new-port case that the deleted comment named still resolves, on attempt two, because loadReconnectRefreshSnapshot re-reads the store after the await. The two-commit regression convention is followed, and the new test blocks refreshFromBackup on a continuation rather than sleeping, which is the right shape.

Fixed: nothing. Both findings need decisions I should not make inside your PR.

F1 (blocking): an empty local store at launch never consults the backup. deferredBackupRefresh is awaited in exactly one place, :3447 inside loadRefreshSnapshotIfNeeded(), and that function has exactly one call site, :3515, inside the for (candidateIndex, mac) in candidates.enumerated() loop at :3458. When candidates is empty the function is never called, so the refresh is never awaited before :3662 concludes .noRoute.

That is the reinstall, upgrade, new-device and local-DB-reset case, which is what #6405 ("don't lose saved hosts/IPs on upgrade") built this ordering for. The Mac is in the per-user backup, local SQLite has zero rows, hasKnownStoredMac is false, and if zero-touch Iroh discovery comes back empty (Iroh blocked, Tailscale-only pairing, broker offline, backoff) the user gets the pairing screen. CMUXMobileRootView.swift:1157-1167 does fire retryActiveMacReconnect on !didReconnect and that path takes the blocking refresh, so it recovers, but the user sees the Mac picker flash plus a whole extra reconnect round trip on every cold launch after an install. That is the screen the deleted comment says we want to avoid showing.

Smallest fix: in the candidates.isEmpty branch, await deferredBackupRefresh?.value and rebuild candidates from a fresh snapshot before concluding .noRoute or calling setHasKnownPairedMac(false).

F2 (blocking): the tombstone replay now races the store read, and loses. refreshFromBackup reaches applyPendingLocalDeletes at BackingUpPairedMacStore.swift:1017, after two awaits (teamIDProvider() at :1014, nonoptionalScopeKey at :1015). loadAll at :3343 is a direct actor read with nothing in front of it, so it gets there first in the ordinary case. On main the replay always completed before the store read.

The comment at :1018 says that replay "must be NETWORK-INDEPENDENT" precisely because it is crash recovery. Scenario: user removes a Mac, app is killed before the tombstone flushes, next cold launch loadAll returns the zombie row, it becomes candidate #1, and we auto-connect to a computer the user deleted. The row then vanishes from Computers while the session stays attached.

Smallest fix: split the deterministic prefix (both applyPendingLocalDeletes calls) out of refreshFromBackup and await that synchronously before the store reads, deferring only the network fetch and merge. Filtering candidates against the pending-delete set would also work but leaves the ordering hazard in place for the next caller.

F3 (worth folding in): the Task at :3295 is never stored and never cancelled. Around a dozen early returns between :3304 and :3662 drop the reference while the restore keeps running against a scope that may already be superseded by a team switch or sign-out. It is also Task<Void, Never>, so await task.value at :3447 does not unwind on cancellation; only the 30s deadline bounds it. async let deferredBackupRefresh = ... scoped to the function is smaller than what is there now and gets cancellation for free.

F4 (dogfood note, no code change): loadPairedMacs() is explicitly bounded so a stalled store cannot hold the reconnect owner, and the concurrent merge now serializes against it on the same actor. A large fleet with a slow merge could push launch hydration past that bound and turn a healthy launch into .failed(.timedOut). New failure mode, worth watching rather than pre-emptively coding around.

CI gap. grep -rn refreshBackupBeforeDial Packages/iOS --include=*.swift | grep -i test returns nothing. There is no test anywhere for the refresh-before-dial ordering this PR changes, and none for "launch with an empty local store restores from backup then connects". Green checks here prove nothing about F1 or F2, and PR checks never compile Release.

This needs device or simulator dogfood before merge, and a macOS fleet build proves nothing for it. Four scenarios, none automated: reinstall then cold launch with the Mac only in the backup (F1); remove a Mac, force-quit before the tombstone flushes, relaunch (F2); cold launch on a slow network with a multi-Mac fleet (F4); background mid-launch-reconnect and return (F3).

Ping me when F1 and F2 are addressed and I will re-review. :)

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Await the deferred backup refresh before selecting reconnect candidates.

When hydratePairedMacs is true, the deferred task starts before loadPairedMacs(), but the local candidate list is built from storedPairedMacsIncludingHidden before the task is awaited. loadRefreshSnapshotIfNeeded() awaits the task only inside the candidate loop. If both candidate arrays are empty, the loop does not run, and the function returns .failed(.noRoute) before backup-restored Macs can enter this attempt.

Move the await before the local snapshot is read, or add an equivalent empty-candidate retry that rebuilds candidates after the refresh. Keep pending-deletion replay as a separate concern unless its path is established independently.

🟠 Major · Await the deferred refresh when the hydrated store is empty. · MobileShellComposite.swift:3390-3396

Packages/iOS/CmuxMobileShell/Sources/CmuxMobileShell/MobileShellComposite.swift:3390-3396
🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Await the deferred refresh when the hydrated store is empty.

When the launch store is empty, no candidates are built. The candidate loop does not call loadRefreshSnapshotIfNeeded(), so the reconnect returns .failed(.noRoute) and clears the known-pairing flag before the backup restore completes.

Suggested fix
-        let loadedMacs = storedPairedMacsIncludingHidden
+        var loadedMacs = storedPairedMacsIncludingHidden
+        if loadedMacs.isEmpty, let deferredBackupRefresh {
+            await deferredBackupRefresh.value
+            if let result = storedMacReconnectInterruptionResult(generation: generation) {
+                return result ? .connected : .superseded
+            }
+            await loadPairedMacs(forceRefresh: true)
+            loadedMacs = storedPairedMacsIncludingHidden
+        }
         let loadedActiveMac = loadedMacs.first(where: \.isActive)

🟠 Major · Bind the deferred refresh to the reconnect boundary. · MobileShellComposite.swift:3291-3304

Packages/iOS/CmuxMobileShell/Sources/CmuxMobileShell/MobileShellComposite.swift:3291-3304
🔒 Security & Privacy | 🟠 Major | 🏗️ Heavy lift

Bind the deferred refresh to the reconnect boundary.

This is a privacy and data-integrity failure, not only a task-lifetime issue. The deferred task can return early from reconnect while refreshFromBackup is still suspended before it registers its restore. Sign-out can then invalidate and drain the current restores, wipe the local store, and the deferred refresh can register afterward with the new boundary generation. Its restore can upsert the former account's saved Macs after the wipe.

Cancel the deferred handle on early exits, and make refreshFromBackup capture the boundary generation before its first await. Check that generation and Task.isCancelled before registering the restore. A defer { deferredBackupRefresh?.cancel() } alone is insufficient because cancellation is cooperative and the restore task is created separately.

Suggested caller change
         } else {
             deferredBackupRefresh = nil
         }
+        defer { deferredBackupRefresh?.cancel() }

🟡 Minor · Bind the deferred refresh to its captured reconnect scope. · MobileShellComposite.swift:3293-3299

Packages/iOS/CmuxMobileShell/Sources/CmuxMobileShell/MobileShellComposite.swift:3293-3299
🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick win

Bind the deferred refresh to its captured reconnect scope.

If currentTeamDidChange() runs after teamIDProvider() returns but before refreshFromBackup captures restoreBoundary.generation, the refresh keeps the old restoreTeam and captures the new generation. PairedMacRestore.run then passes that generation check, fetches the old-team snapshot, and calls upsertIfNewer with the old account/team scope. The stale row can reappear when the user selects the old team. The new team list remains correctly scoped, so this does not establish immediate cross-team display.

Pass the caller's captured account/team scope and boundary generation into the deferred refresh, and abort before restore registration when that generation is no longer current. Do not resolve the team live inside this detached task.

P3: `visibleAnchor(in:)` has no production caller — its only consumer is the assertion in `UpdatePillReleaseVisibilityTests`, so this is a test seam added to the production registry. Either wire the keyboard-opened-notifications path to use it, or move/guard it as test-only instead of shipping a registry API nothing in the app calls.</violation>

P3: `allObjects.first` returns an arbitrary anchor when a window has several registered, visible anchors, since `NSHashTable.allObjects` has no defined ordering. If this is intended to pick where keyboard-opened notifications appear, the popover position becomes nondeterministic; select deterministically (fixed priority, or reuse the production path's anchor resolution) rather than relying on hash-table iteration order.</violation>
