Suggested reviewers: Merge Risk: 🟡 Moderate · up to Mac-only hosting and sidebar terminal deletion may not work as intended, and the close regression tests need correction. Resolve these issues before merging. Security Architecture ReviewSecurity architecture risk: 🟡 Moderate · up to Discovery is more tightly scoped, but one access-setting combination appears inconsistent with the permissions service. Remote terminal closure also introduces a destructive cross-device operation whose authorization and recovery behavior need confirmation. Retained concerns

A Durable Object reset (deploy, rollback, runtime restart) drops sockets without running webSocketClose, so their reservations and unacknowledged output stay in the user's 8 MiB aggregate budget. On 2026-09-25 this left a heavy user unable to receive directory responses, then unable to open sockets at all, reported only as internal_error. - storage: the harness reports the public code of classified failures, and the aggregate output cap must yield slow_consumer (today a raw DrizzleError leaks because the trigger message sits on error.cause). - runtime: seed four leaked reservations filling the budget, then open a socket and request the directory. Today the socket open fails. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
…put cap - socket-store: read trigger guards through the error cause chain. Drizzle wraps a RAISE as "Failed to run the query", so the output cap surfaced as internal_error (500) instead of a retryable slow_consumer (429). - team-control: when setOutput hits the aggregate cap, release reservations no owning TeamControl holds as live or opening sockets, then retry once. This reuses the sweep reserveSocket already ran at the reservation cap. - observability: record a sanitized cause (names and messages along the cause chain, no SQL text or bound parameters) for unclassified socket and UserUsage failures, so the next internal_error names what failed.

Inline comments:
In `@cmuxTests/CloudNativeLayoutProjectionTests.swift`:
- Around line 88-90: Update the close-event setup in both affected tests to call
catalog.endProjections with the intended close reason, allowing the catalog to
remove the projection and forward the event to the coordinator in production
order. Remove the direct coordinator.projectionDidEnd call and the separate
replacement-reason call.
In `@Resources/Localizable.xcstrings`:
- Line 552995: Add non-empty translations for the devices.options.hint catalog
entry in the missing locales bs, da, it, km, nb, pl, pt-BR, ru, th, tr, and uk,
preserving the existing translations for other locales.
In `@Sources/Devices/DeviceSurfaceProvider`+Mutations.swift:
- Around line 109-114: Update DeviceWorkspaceLayoutCoordinator.performClose to
match surface IDs case-insensitively and throw an error when the surface is
absent for a sidebar close with no workspaceID. Preserve silent success for
absent surfaces on mirrored-pane closes with a workspaceID.
In `@Sources/Mobile/MobileHostIrxRuntime.swift`:
- Line 166: Update MobileHostIrxRuntime.superviseConnection to identify the peer
before admission: allow authenticated Mac peers according to
MobileRemoteControlPolicy.allowsIncomingAccess(), and require pairingEnabled()
for iOS peers instead of rejecting all connections at the pairing guard. Keep
the host-start condition unchanged and add coverage for an authorized Mac
connection and a refused iOS connection when incoming access is enabled but
pairing is disabled.
In `@workers/iroh-v2/e2e/permissions-runtime.test.ts`:
- Around line 121-123: Add a positive-control assertion in the test before the
iOS exclusions: verify the Mac host’s directory includes the dialer’s expected
grant. Keep the existing iOS assertions so the test checks both that the grant
exists for Mac-to-Mac and is excluded for iOS.
In `@workers/iroh-v2/e2e/storage-runtime.test.ts`:
- Line 162: Update the renewal assertions in both tests around observeAuthority
to verify each renewal returns a non-null revision that increases from the
previous one. Read back the authority record and assert its verification and
expiry times were updated, including in the full-ring case; keep the existing
device-list assertions.

Macs appear in My Devices only while the authenticated Mac directory advertises incoming access. Registry, presence, pairing, and retained rows enrich those devices without resurrecting opted-out hosts. The new membership policy is isolated in the existing
CmuxSurfaceCatalogModelpackage and tested without the app host.Mac discovery, Mac hosting, and iOS pairing have separate gates throughout control-session setup, directory grants, cached inbound authority, and runtime admission. A Mac-only host can accept an authorized Mac while refusing iOS peers when pairing is off. Same-account, namespace, build-tag, endpoint, expiry, and revocation checks remain enforced.
Closing a terminal in a synchronized Mac workspace closes that terminal on the owning Mac through the existing workspace-scoped
mobile.terminal.closerequest. Closes share ordering with layout writes, validate the reply, and reconcile from the owner after success or failure. Workspace teardown and disconnect only detach. Sidebar closes reject missing targets and match UUID casing. Workspace deletion passes its known owner, and individual closes use an index built from the accepted mirror.The Devices controls and ⋯ menu remain available after peers appear. The row uses the full highlight area and machine alignment, Computers follows Mobile in Settings, and the left sidebar retains the source Mac label and computer icon across a transport disconnect. The menu hint has translations for all 20 catalog locales.
This branch incorporates the original socket-reset recovery commits from #14386. The incident investigation there identified leaked WebSocket reservations after Durable Object resets, exhausting a user's aggregate output budget and surfacing wrapped SQLite cap errors as
internal_error. Recovery checks live/opening sessions before reclaiming stale reservations and retries the capped write once. This follow-up bounds concurrent owner checks, restricts diagnostic fields to known categories, and tests three successive leaked budgets on an existing socket while preserving its live reservation. Worker names, Durable Object bindings, reader-first schema-6 writes, and deployment/rollback guards are preserved. The development Worker is deployed at2fd9d268a7(its Worker source matches the final app head), with unchanged Durable Object namespaces and verified reader7/writer6 health. Production was promoted through the guarded staging/production scripts to version997d7d0f-f40c-4718-a05f-0112fb6e0d40at sourcec25a3e3032. Signed staging protocol checks passed, including the existing client forwarding address. The 910-second production watch completed with 579 HTTP/socket operations, zero unexpected request failures, and 46 passing health checks. Across the complete capture, the new version handled 919 HTTP/socket operations with zero unexpected request failures. One handover HTTP 500 belonged to the old version; two later inactive-instance disconnect exceptions remained below the baseline rate. No rollback was needed. The saved rollback target isbd1538b8-b29f-430f-a33f-119bd41e4118.Validation on
