When T3 Code compacted a thread, the timeline showed a /compact user bubble, a "Working for Ns" row and a live "Compacting context" divider: two bars for one action. The automatic compaction before cache expiry also sent a Done notification on every idle thread.

What changed

• One status, never two. The /compact bubble is gone. When you send to an idle thread, the compaction holds your message back, so the working row says why: "Compacting after being idle…". Every other compaction shows only its live divider ("Compacting before the cache expires…", "Compacting context"), with no working row above it. When the compaction finishes, the divider leads with why: "Context automatically compacted before cache expiry 252K → 18.3K tokens" or "Context compacted after being idle …".
• Provider compactions are unchanged. When Claude compacts on its own in the middle of a turn, the live divider stays, because by then the working row is usually off screen.
• Why it compacted. The /compact T3 Code sends now carries idleCompaction: "onReturn" from the composer when you send to an idle thread, "beforeCacheExpires" from the server's idle timer. It travels through message.dispatch, the message and the user turn item to both clients. Messages from older servers fall back to the agent/server origin.
• Background compactions stay out of lists and notifications. The thread shell (SQL and in-memory paths) skips runs whose prompt is one of those /compacts, along with the prompt itself, unless the compaction fails. The sidebar, inbox and mobile list never flip the thread to Working or move it, there is no Done notification, the relay (mobile Done alerts and Live Activity) stays quiet, and auto-settle timing is untouched. Failures still surface, and a /compact you type behaves like any turn. The open thread still shows the compaction, because it reads the full projection.
• Claude's resume question. When Claude asks "Compact it before continuing?" and you choose to compact, the answered question folds into the compaction row ("Context compacted after 1h 12m idle …").
• Mobile. Mobile gets the same folding and notes. It has no "Working for" row, so it keeps a single compaction divider.

Evidence

The recordings are real Claude turns on a dev server. To avoid waiting an hour, the idle thresholds were shortened for recording only (1 minute for case 1; for case 2, 15 seconds after the turn and no context minimum). That patch is not part of this PR.

Case 1: sending a message to a thread that has gone idle

The composer compacts first, then sends your message.

Before	After: compacting	After: done

Recording (made before the divider copy change, so its last frame still reads "… · After being idle"): https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/f0b5d15a1e3358ad/compact-on-return.mp4

Case 2: automatic compaction before the cache expires

A turn finishes, then T3 Code compacts the thread on its own.

Before	After: compacting	After: done

Recording: https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/a98be610277dd893/automatic-compaction-divider.mp4

Sidebar check (live, case 2): sampling the sidebar row every 250 ms, the user's turn showed "Working 0s → 1s", then during the automatic compaction (18.5–24.8 s) the row stayed "now" with no Working state and no position change, while the timeline showed the live divider.

Case 3: typing /compact

Before	After: compacting	After: done

The "before" capture is case 1's screenshot: a typed /compact rendered identically. Recording: https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/caf6521114d77c3f/compact-command-divider.mp4

Case 4: a /compact that fails

Claude Code echoes /compact's stdout ("Not enough messages to compact.") as a synthetic assistant message and as the result text. The adapter now drops both for /compact turns. The reason goes on the failed compaction item's summary, and the divider shows it in the error style.

Before	After

Tests

• ProjectionStore.test.ts: a running idle compaction (server or on return) is not the shell's latest, active or activity run and its prompt is not the latest user message, in both shell paths; a typed /compact and an ordinary prompt are; a failed idle compaction surfaces.
• agentAwareness.test.ts: a silent run stays quiet unless it fails.
• ClaudeAdapterV2.test.ts: a failed /compact carries its reason on the compaction item, whether Claude reports it with compact_error or only as the result text, and no /compact turn emits a reply.
• MessagesTimeline.logic.test.ts: compacting on return is the working row alone; automatic and typed compactions are their live divider alone; an answered resume question folds into its compaction.

Not run: mobile in a simulator.

Takeover

Rebuilt on the original branch, preserving the contributor history and merging main. Removed redundant timeline state; fixed pending mobile controls, runless/retry rows, item-scoped resume reasons, collapsed dividers, and the item/run completion transition.
Product decisions: successful automatic compactions stay quiet; typed compactions and failures notify. Web/desktop use the working row only when compacting on return and one live divider otherwise; mobile uses one divider. Both new wire fields remain optional. Julius approval remains required for this feature; this PR is not merged.

Evidence

The original evidence above is historical. The takeover matrix below uses the real web dev app, isolated synthetic state, an offline gated provider, and unmodified compaction paths; no live provider account.
[9c717508] versus [27e0c684]: manual, idle-on-return, pre-expiry, and provider mid-turn; running/finished; light/dark; 1440/390 CSS viewports. The final main merge changes only upstream analytics; web, mobile, orchestration, contracts, shared, and client-runtime Git tree hashes match this captured head exactly. The head fixture also holds a completed compaction item while its run is still running, and includes a reconnect control.
[Full fixture matrix and verification artifacts] — 64 stills, 32 sampled transition clips, 32 paired diffs; independent final evidence audit: PASS.


Running to finished transition.
Clips contain eight real timestamped preview frames, without interpolation, plus a one-second final hold. Preview output scaling and dynamic layout differences are documented in the archive.

Verification log

• HEAD: 7ab6cddc; refreshed main is an ancestor (merged by commit, never rebased).
• Initial focused client/shared baseline: 119 → 123 passing; regression reverts failed as expected. Final merged head: 206 focused tests, 19 Chromium browser tests, and 16 upstream analytics tests passed. The full projection suite (42) and compaction-filtered server run (21, overlapping) were already green.
• Scoped lint, formatting, diff checks, and web/mobile/server/contracts/shared/client-runtime typechecks passed. Browser execution: both changed files explicitly ran under the web browser project, 19 passed.
• Two fresh full-diff reviewers returned MERGE on final merge head 7ab6cddc (round 7). Earlier rounds fixed mobile pending attachments, runless ownership, retry IDs, and resume reason ownership. Historical bot and visual audits additionally exposed collapsed dividers and the transient duplicate row; both now have failing-before regressions.
• Steering objections were withdrawn: command policy queues work behind maintenance, and the orchestrator rejects steering into a maintenance run. The accessible reason and SQL text/attachment parity findings are addressed. All seven historical inline findings were rechecked.
• Optional fields decode older payloads; old/new peer round-trips passed. Mobile reconstructs reasons per compaction item and keeps pending controls/attachments.
• Unverified: native mobile simulator, Electron shell, real providers, relay/tunnel, OS notification delivery, native resume-question and failure/no-token visuals. Notification and fallback behavior are covered by focused tests.
• Evidence is external only; no fixture, screenshot, recording, or scratch artifact is committed.

Walkthrough

The changes add idle-compaction metadata and recognition helpers, present compaction activity in web and mobile timelines, and mark eligible idle-compaction runs as silent in thread shells. Awareness and completion notifications use the silent-run state, while failed compactions remain visible.

Changes: Compaction handling

Layer / File(s)	Summary
Compaction metadata and orchestration packages/contracts/src/orchestrationV2.ts, packages/shared/src/claudeCompaction.ts, packages/client-runtime/src/operations/commands.ts, packages/client-runtime/src/userMessage.ts, apps/server/src/orchestration-v2/Orchestrator.ts, apps/server/src/orchestration-v2/IdleCompactionService.ts, apps/web/src/components/chat/useComposerSend.ts, apps/web/src/session-logic.ts, apps/web/src/types.ts	Contracts add idle-compaction metadata and helpers to recognize compaction commands. Client and server paths propagate the metadata. Shared helpers derive Claude resume-compaction ages, and server code uses shared compaction text and answer-label constants.
Claude compaction results and failures apps/server/src/orchestration-v2/Adapters/ClaudeAdapterV2.ts, apps/server/src/orchestration-v2/Adapters/ClaudeAdapterV2.test.ts	The Claude adapter excludes synthetic compact replies and records available result or failure text on compaction items. Tests cover compact results, failures, and assistant-message events.
Silent-run projection and suppression apps/server/src/orchestration-v2/ProjectionStore.ts, apps/server/src/orchestration-v2/ProjectionStore.test.ts, packages/shared/src/agentAwareness.ts, packages/shared/src/agentAwareness.test.ts, apps/web/src/components/ThreadNotificationCoordinator.tsx, apps/web/src/components/ThreadNotificationCoordinator.badge.browser.test.tsx	The shell projection sets latestRunSilent for eligible idle-compaction runs and resets it when a usage-limit failure replaces the presented run. Awareness suppresses starting, running, and completed phases for silent runs. Completion notifications also exclude silent runs.
Web compaction timeline rows apps/web/src/components/chat/MessagesTimeline.logic.ts, apps/web/src/components/chat/MessagesTimeline.tsx, apps/web/src/components/chat/TimelineWorkGroupRows.tsx, apps/web/src/components/chat/MessagesTimeline.logic.test.ts, apps/web/src/components/chat/MessagesTimeline.browser.test.tsx	The timeline builder represents compaction commands and related work as compaction rows, derives labels and titles, and renders failure details. Tests cover running, completed, and failed compaction rows.
Mobile compaction feed presentation apps/mobile/src/lib/threadActivity.ts, apps/mobile/src/lib/threadActivity.test.ts, apps/mobile/src/features/threads/ThreadFeed.tsx, apps/mobile/src/features/threads/pending-thread-feed.ts, apps/mobile/src/features/threads/pending-thread-feed.test.ts	The mobile feed identifies compaction runs, suppresses matching command and answer rows, and omits the live thinking row for an active compaction command. Compaction dividers show idle-compaction or idle-duration labels and failure details when available.

Keep compaction groups visible when folding a run.

deriveThreadFeedRunFolds can hide the standalone compaction group when the same run contains other foldable entries. The presentation then removes the /compact message and shows only the work fold.

Do not remove the only visible compaction row.

If a completed /compact turn has other foldable work, deriveTurnFolds hides its compaction work entry. This branch then suppresses the prompt because hasItem is true. The collapsed timeline shows the work fold but no compaction row. Keep compaction entries visible when deriving the fold, rather than treating a hidden compaction item as the prompt’s visible replacement.

Make the SQL silent-run predicate match idleCompactionOf.

If a message.dispatch contains /compact, an attachment, and idleCompaction: "onReturn", this SQL predicate sets latestRunSilent to true. idleCompactionOf rejects the same message because it has an attachment. The SQL shell can therefore suppress a completion notification that the in-memory shell allows. The SQL predicate also misses trimmed or case-varied /compact text that the helper accepts. Apply the helper’s text and attachment checks in SQL. As per coding guidelines, “Hit every surface” includes the shell’s downstream clients.

Update the SQL silent-run predicate near `latestRunSilent` to match
`idleCompactionOf`: reject messages with attachments and apply the same trimmed,
case-insensitive `/compact` text checks as the helper. Keep the change scoped to
this predicate.
