cmux-tui: durable agent notifications with per-client read state (notification.ack) - #12108
Conversation
…ification.ack) Agent hook transitions (turn completed, approval, question, plan review, error) now post durable notifications through the notification.create effect path under a sequence-derived key, so they survive daemon restart and reach every resource-feed subscriber. The legacy notify verb uses the same path. New notification.ack records per-client read marks in resource_notification_reads, publishes refreshed rows as one revision, and every notification row carries read_by. The shared console unread marker is unchanged. Claude-Session: https://claude.ai/code/session_01ND7TVwfSibPfKCv8j8Sb8j

In `@cmux-tui/crates/cmux-tui-core/src/mux.rs`:
- Around line 5809-5817: Update apply_agent_hook_record’s notification handling
around create_durable_notification so a failure to commit the attention
notification does not abort the agent-state projection or fence commit. Preserve
the notification attempt and add only the minimal non-fatal error handling
needed to allow the agent report and fence to commit; do not alter durable
notification behavior for other callers.
In `@cmux-tui/crates/cmux-tui-core/src/workspace_registry/resource_store.rs`:
- Line 1053: Update the eviction transaction around the
resource_notification_reads query to accept and use the exact evicted
notification IDs from the authoritative ledger, deleting only those read marks
instead of scanning the entire table. Keep the normal notification.ack path
limited to the requested client read marks, and preserve the existing
transaction behavior for non-eviction acknowledgements.
In `@cmux-tui/crates/cmux-tui/src/cli/command.rs`:
- Around line 1342-1351: Update the acknowledgement flow to use localized
catalog entries for the new UsageError messages around ids validation in
cmux-tui/crates/cmux-tui/src/cli/command.rs lines 1342-1351. Update
cmux-tui/spec/cli.md lines 330-338 to source the acknowledgement prose from
locale-specific documentation and change “install has read” to “installation has
read.” Add matching notification documentation for every supported locale in
docs/cloud-cmux-tui-daemon.md lines 543-587.
In `@cmux-tui/spec/resource-operations-v2.json`:
- Line 7321: Update the schema definition for client_id near the durable
acknowledging-client identity field to enforce non-empty ASCII graphic
characters only, while retaining the maximum length of 128. Ensure invalid
spaces, control characters, and non-ASCII values are rejected during API
validation.

…es; skip indeterminate hook notifications Review fixes: notification.ack no longer scans or prunes the read table against the in-memory ledger (a create in flight could evict a row the receipts still retained). Eviction pruning now rides a committed create, deletes only ids the committed receipts no longer retain, and a restart sweeps marks outside the retained window. An indeterminate notification effect is skipped with a diagnostic instead of wedging the agent-hook fold on the same key forever.

Cloud notifications, part 1 of 2: the VM's cmux-tui daemon becomes the source of truth for notifications, with per-client read state. Part 2 (macOS) subscribes through the existing per-machine state feed and drives tab, workspace, right-sidebar, system, and CLI unread from it. Design:
docs/cloud-cmux-tui-daemon.md, "Notifications: the VM is the source of truth".Agent hook transitions that deserve attention (turn completed, approval, question, plan review, error) now post a durable notification from inside the journal fold, through the same
notification.createeffect path the resource API uses, under a key derived from the journal sequence. A crash between the notification commit and the agent-report commit replays the notification on retry instead of posting twice. Prompt text is redacted by policy, so the body carries only the tool name an approval waits on. The legacynotifyverb uses the same durable path, so every notification survives a daemon restart and appears on thesession current eventsfeed as anotificationupsert.New
notification.ack {client_id, notifications[]}records per-client read marks in a newresource_notification_readstable and publishes the refreshed rows as one revision. Every notification row now carriesread_by. The sharedunreadmarker on the console tree is unchanged, so two clients of one machine keep independent unread state. Ids the 256-entry ledger evicted come back asunknown, not an error, and their read rows are pruned in the same transaction. CLI:notification ack --client <id> <ids>....Tests (cmux-tui-core): hook transitions post once and replay-safe; ack is per client, replay-safe, emits one upsert delta per row, rejects a bad client id; read marks survive restart and eviction prunes them; a 400-step randomized run of creates, acks from three clients, replays, and restarts holds the invariant that a retained row's
read_byequals the set of clients that acknowledged it. Verified on a Blacksmith testbox: fullcargo test --lockedandcargo clippy --all-targets -D warningsclean, spec checkers and SDK descriptors regenerated.Closes #11641 (the inverted, listener-based design).

Note
Medium Risk
Touches durable mutation/replay, SQLite schema, journal-fold ordering for agent hooks, and public API contracts; behavior is heavily tested but multi-client notification state is easy to get wrong in clients.
Overview
Adds
notification.ackto the resource API (126 transported operations) so each client install can record which notifications it has seen. Notification rows now includeread_by; marks persist inresource_notification_readsand are restored on restart, while the shared consoleunreadmarker is unchanged.Durable notification pipeline: Agent hook transitions that need attention (turn complete, approval/question/plan review, error) post through
create_durable_notificationbefore the agent report commits, with idempotency keyed by journal sequence. The legacynotifyverb andnotification.createshare the same effect path so posts survive restarts and show up on the session events feed. Evicted ledger entries return asunknownon ack; read rows are pruned when creates commit.Surface area: CLI
notification ack --client <id> <ids>..., catalog/bindings/spec/docs updates, and extensive mux/registry tests (replay, multi-client, restart, eviction, fuzz).Reviewed by Cursor Bugbot for commit 6b0f6b4. Bugbot is set up for automated code reviews on this repo. Configure here.
