Sync My Devices notifications into the local sidebar - #15198
Conversation
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
A DeviceLink never followed the other Mac's notification feed, so cmux notify on a paired Mac never reached this Mac. The device provider now pulls notification.feed.list on connect and on notification.feed.changed, and feeds it through the same CloudNotificationSync a Cloud machine uses: placement on the mirroring pane, the shared admission gate, local delivery with a device-mac origin, and notification.feed.mark_read for local reads. Hosts omit records they mirrored from another Mac, and clients skip cloud-vm rows, so two Macs never relay a notification back and forth.

📝 WalkthroughWalkthroughThe change adds notification-feed synchronization for linked device Macs. It parses and filters host feed records, maps them to local terminal or workspace destinations, delivers them with a device-specific origin, and propagates read state. Feed-change events and reconnects trigger refreshes. Mirrored device-origin records are excluded from onward mobile feeds. ChangesDevice notification synchronization

Merge Risk: ⚪ Minimal · up to Device notifications are now mirrored into local views. The remaining gap could let a future regression hide an unread indicator in one view, but does not establish a current production failure. Security Architecture ReviewSecurity architecture risk: 🟡 Moderate · up to Notifications from another Mac now enter the local notification system. Existing controls limit delivery, but the feed change also means a phone connected to only one Mac can miss notifications mirrored from another.

Dogfood build of cmux DEV pr-15198-817ecc86.app The link opens this exact commit in the cmux dev menu bar app. The build starts on each push and the page waits until it is ready; a newer push replaces it. It signs in against production, so Cloud or backend changes still need a tagged build with a development backend. |

This retries a coalesced feed change after a connected request failure without
retrying indefinitely.
- Around line 20-29: Update the `DeviceLinkError.hostRejected` handling in the
`send` closure so only the `invalid_params` rejection is consumed; rethrow other
host errors, including authorization failures, to keep the batch pending.

Assert both terminal projections appear.
The setup renders the terminal under its workspace and in the Terminals pool. !rows.isEmpty passes if either projection is missing, and the quiet-state check reuses that incomplete count. Require both rows explicitly.
Suggested assertion
- #expect(!rows.isEmpty && rows.allSatisfy { $0 })
+ #expect(rows.count == 2 && rows.allSatisfy { $0 })📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Summary
cmux notifyin a terminal on another Mac under My Devices printedOK notification:<id>on that Mac, but this Mac showed nothing: no sidebar badge, no banner.DeviceLinksubscribed to workspace and terminal topics only, and nothing on the device path turned the other Mac's notifications into local records. Cloud machines worked becauseCmuxTuiSurfaceProviderruns aCloudNotificationSync.The device provider now runs the same
CloudNotificationSync. It pullsnotification.feed.listafter each connect and onnotification.feed.changed. It places each row on the pane that mirrors the terminal, or else on the local workspace that shows the terminal's remote workspace. Delivery uses the shared admission gate and the newdevice-mac:<device>origin, which gets the same untrusted-text clamps ascloud-vm. A local read or dismissal sendsnotification.feed.mark_readto the other Mac. The Devices tree gets the unread dot too: the hub key is now parsed withSurfaceMachineID(rawValue:)instead of always.cloud.Loop and duplicate prevention: hosts leave records mirrored from another Mac out of
notification.feed.list. Feed items now carryorigin_kind, and clients skipcloud-vmanddevice-macrows, because this Mac gets those through its own sync.Known limits: a notification read on the other Mac stays unread here (same behavior as Cloud rows read by another client). Phones connected only to this Mac no longer see device-mirrored records in the feed.
Testing
cmuxTests/DeviceNotificationSyncTests.swift: feed parsing and origin skip, origin wire round trip, host feed filter, provider hub registration and pane placement, and the Devices tree unread dot. Commit 1 adds the tests (red: the types do not exist), commit 2 adds the fix.python3 scripts/verify-local.py: passed.devnotif-v1.
