fix(pi): a steer Pi has not read yet shows as waiting, not steered - #33982
Cause: Orchestrator.appendSteeringMessage stores every steered user_message as completed when it is offered, and the Pi adapter ignored Pi's signals that a steer is queued and later read, so nothing could show that a steer behind a long-running command is still unread. Fix: (1) provider-core gains a steer.updated provider event {threadId, runId, messageId, status: pending|completed|cancelled}. (2) The Pi adapter tags steer prompt sends with their messageId. When Pi acks the steer with disposition "queued" it adds the message to the turn's unread list and emits pending. On message_start with role "user" it takes the oldest unread steer and emits completed (Pi reads steers in order). When the turn finalizes, any steer still unread is emitted as cancelled if the turn was interrupted (Stop clears Pi's queue) and completed otherwise. (3) ProviderEventIngestor turns steer.updated into a turn-item.updated on the stored user_message (id from idAllocator.derive.userTurnItem), changing only pending/completed items; RunExecutionService routes the event by runId. (4) The web TimelineUserMessageRow marker and the mobile intent badge read 'Steer · waiting to be read' while the item is pending; a cancelled steer shows the existing 'cancelled' status chip. Other providers are unchanged because they never emit the event. Server-side checks for active work (ProjectionStore SQL, RunExecutionService background tracking) only count tool and subagent items, so a pending user_message does not hold a run open. Reproduced against the real Pi 1.5.2 RPC: a steer sent during sleep 20 was acked {disposition: queued} at 7.2 s; queue_update emptied and message_start(role user) for the steer arrived at 25.2 s, when the bash tool ended. Before the fix that window showed 'Steered'; the item now stays pending until the read. Known limit: if a steer is sent before Pi has emitted message_start for the turn's own prompt, that message_start can be taken as the steer's read, so the steer never shows as pending (today's behaviour, never a stuck pending). No new regex or parser: the change reads two existing JSON fields (data.disposition, message.role) with the adapter's existing record helpers, constant time per event.
Commit e5b0718 (origin/main). Ran T3CODE_DEV_SEED=0 vp run dev in a fresh worktree (fresh database), paired the web client in the preview browser, added a Pi provider instance under Settings > Providers (Pi CLI 1.5.2 through the hub, model 'Pi default'). Follow-up behavior was the default, Steer. In a new Pi thread I sent: "Run exactly one bash command in the foreground: sleep 90; date -u; echo poll-done. Then reply with one short sentence." While the timeline showed 'Running sleep', I sent "STEER: when you reply, start with the word BANANA." Observed: the message appeared at once with the 'Steer' marker. The projection (orchestration_v2_projection_turn_items, read-only) recorded the steered user_message as status=completed at 16:44:55.9Z. Nothing new appeared in the thread except 'Working' / 'Running sleep' until the command_execution item completed at 16:46:00.9Z (65 s later). The assistant reply at 16:46:05.8Z began 'BANANA: the command finished at ...', in the same run (run completed 16:46:07). So the steer was offered and marked delivered immediately, but Pi only read it at the next step boundary, after the blocked command returned, with no visible state in between. Text-only steer; I did not attach an image. I saw a single run row, not the reporter's created-then-cancelled extra run.
Evidence
In an empty thread titled Pi steer evidence, run sleep 90; date -u; echo poll-done in the foreground. Ten seconds after Running sleep appears, send STEER: when you reply, start with the word BANANA. Record through the reply. For the Stop case, interrupt ten seconds after submitting the steer.

Tests
Before the fix: real pi --mode rpc driver (scratch, not committed) confirmed queued ack at 7.2 s and user message_start at 25.2 s after a 20 s sleep. After the fix: vp test run src/server/adapter.test.ts in packages/provider-pi: 121 passed, including the new 'reports a queued steer unread until Pi reads it / Stop clears it unread' cases. vp test run src/orchestration-v2/ProviderEventIngestor.test.ts src/orchestration-v2/RunExecutionService.test.ts in apps/server: 94 passed, including the new 'keeps a steered message pending until the provider reports it read'. vp run check:changed: lint, knip, typecheck (27 packages), tests (4 files, 217) and react compiler passed; format failed, was fixed with vp fmt, and the pre-push hook's fmt/lint/knip then passed. No UI run of the label.
Not in this change
Claude counterpart of the same unread-steer state (https://git.cafe/pingdotgg/t3code/issues/23948): the event and ingestor path are generic, but the Claude adapter does not emit steer.updated.
https://git.cafe/pingdotgg/t3code/issues/15708: Stop drops an unread steer. This change marks it cancelled (Pi's existing 'Stop cleared N queued messages' notice still lists it) but does not resend it.
When several steers are grouped (continuesSteer), only the first shows the marker, so a later unread steer in the group shows no waiting label.
With Pi older than 0.84.4 (no clear_queue), a steer marked cancelled on Stop can still be read on the next prompt.
AI-assisted; verified with the tests and tools listed above.
Pi queues a steer sent during a running command and reads it only at the
next step boundary, after the command returns. The steered message was
stored as completed the moment it was offered, so the thread said
"Steered" and then showed nothing new for minutes.
The Pi adapter now reports a `steer.updated` provider event: pending when
Pi acknowledges the steer as queued, completed when Pi starts the user
message that delivers it, and cancelled when Stop clears it unread. The
ingestor applies that status to the stored user message, and web and
mobile label a pending steer "Steer · waiting to be read".

Macroscope's review found this PR approvable — Pi steers now show as waiting until read, with status updates reflected on web and mobile. The change is limited to message-status tracking and presentation, without changing how steers or commands execute.
You can add or adjust custom eligibility rules. Learn more.
The Pi adapter now reports when a steer is queued, read, or cancelled. Server event handling updates the projected user-item status. Mobile and web chat markers identify pending steers as waiting to be read.

Summary
Pi steer status events packages/provider-core/src/server/ProviderAdapter.ts, packages/provider-pi/src/server/adapter.ts, packages/provider-pi/src/server/adapter.test.ts
The provider event contract adds steer.updated. The Pi adapter reports queued steers as pending, marks them completed when a user message starts, and reports unread steers as completed or cancelled at turn finalization. Tests cover queued, read, and interrupted cases.
Server routing and projected status apps/server/src/orchestration-v2/RunExecutionService.ts, apps/server/src/orchestration-v2/ProviderEventIngestor.ts, apps/server/src/orchestration-v2/ProviderEventIngestor.test.ts
The run service routes steer updates for its current run. The ingestor updates supported user turn items and clears completedAt when setting an item to pending. Tests cover pending and completed status changes.
Mobile and web markers receive whether the projected item is pending. Unread steers display “Steer · waiting to be read” with explanatory accessibility text or tooltip. Other steers retain their existing marker behavior.

Explanation
Issue [#33776] requires the Pi Steer message to show that it is unread until the agent reads it, or to keep the blocked command visibly active. The Pi adapter emits steer.updated as pending when Pi reports disposition: "queued", then emits completed when Pi starts a user message or the turn settles normally. The server projects these updates onto the stored user message. Web and mobile show “Steer · waiting to be read” while the item is pending. The adapter tests cover both read and Stop-cleared outcomes, and the ingestor test covers the pending-to-completed projection. The implementation addresses the unread-indicator acceptance criterion.

The test covers pending to completed. The cancelled path is the one that writes a new status through the same branch. Add one assertion to the existing test: send pending, then cancelled, and check the projected status. This extends the existing case, as the testing rules require.

Announce the steer status change to screen readers.
When the projected item changes from pending to completed, this argument changes the badge’s accessibility label. The accessible View at Lines 2146-2157 has no live-announcement behavior, so a user who remains on the thread may not hear that the steer was read. Add a polite status announcement for the transition. Based on learnings, “dynamic status regions” need live-region semantics unless an accepted alternative announces the update.

Announce the waiting-label transition to screen readers.
When unread becomes false, this text changes from “Steer · waiting to be read” to “Steer”. The marker has no live-region semantics, so a screen-reader user who remains on the thread may not hear that the steer was read. Give the changing status text a polite live region.
