fix(server): Claude background commands show how long they have run - #26668
Claude background commands never showed how long they had been running. Codex and turn-item tasks did. Claude's SDK names a background task by its own task_id (for example bdqirlcyw), but the timeline item for the Bash call that started it is keyed by the tool call id (toolu_…). The background work line looks the item up by task id to get startedAt, so for Claude it never found one.
Change
Pending background tasks get an optional nativeItemId, the native id of the turn item that started the work, set only when it isn't taskId.
The Claude adapter remembers task_id → tool_use_id from every local_bashtask_started. That includes foreground commands, since they can move to the background later. The background_tasks_changed roster carries ids only, replaces the whole set, and usually arrives before task_started, so both paths stamp nativeItemId from that map. task_notification drops a task's link, so the map only holds live tasks. It's also capped at 64 entries, like the adapter's other per-task maps. A roster update keeps the link a pending task already has, so a long-running command never loses it.
The web matches the turn item on nativeItemId ?? taskId.
I extended uses task_started as an incremental roster fallback… in ClaudeAdapterV2.test.ts. A backgrounded task_started links the task to its tool call, a foreground one keeps its link once a roster lists it, and a later roster replace keeps both. It fails on main with expected undefined to equal 'toolu_01Rs…', and it also fails if the foreground return moves above the map insert.
Two exact-shape expectations now include the field. One of them, keeps a running Claude monitor typed after many newer monitors end, is the long-running case: before the roster fix it silently lost the link.
The recorded claude_background_monitor_wake replay, a real Claude session, now shows the Monitor task carrying its real tool call id toolu_019b4E… once task_started links it. Its expectation is updated.
Astra (gpt-6-astra) reviewed it and found the eviction gap and the missing foreground case. Both are fixed here.
On a dev server, a real Claude Haiku turn ran sleep 900 in the background, and the line showed 52s. Stop still ended it.
vp run check:changed passes format, lint, knip, and typecheck across 32 packages. In ClaudeAdapterV2.test.ts, 13 tests fail on this Windows machine, the same 13 on main (attachment path cases, and one that reads the local Claude settings). Everything else passes.
Not covered: mobile shows no elapsed time today, so nothing changes there.
Made with Claude Opus 5.5 in Claude Code, inside T3 Code.
Claude names a background task by its own task id, while the timeline item for
the Bash call that started it is keyed by the tool call id. The background work
line looks the item up by task id, so it never found it and Claude commands had
no elapsed time. The adapter now remembers each task's tool call from
task_started, roster updates included, and pending tasks carry it as
nativeItemId for the web to match on.

The task-to-tool-call map is capped, so a command that outlived 64 newer tasks
lost its link and its elapsed time on the next roster update. Roster updates now
keep the link a pending task already has. The roster test also covers a
foreground command that moves to the background.

Macroscope's review found this PR approvable — Claude background commands now link to their originating timeline items so elapsed runtime can be displayed. The change is limited to task metadata and presentation, retaining the existing fallback when that link is unavailable.

Walkthrough
The pending background-task contract now includes an optional native turn-item ID. The Claude adapter records task-to-tool-use ID associations and includes them in pending-task records. The chat UI uses the native ID to match pending tasks to turn items.

Summary
Capture and propagate tool-use IDs packages/contracts/src/orchestrationV2.ts, apps/server/src/orchestration-v2/Adapters/ClaudeAdapterV2.ts, apps/server/src/orchestration-v2/Adapters/ClaudeAdapterV2.test.ts, apps/server/src/orchestration-v2/testkit/fixtures/claude_background_monitor_wake/output.ts
The pending-task contract adds optional nativeItemId. The adapter records task-to-tool-use ID mappings for non-subagent tasks, uses roster entries to restore mappings when needed, and includes available IDs in pending-task records. Tests and the monitor fixture check native IDs in roster entries.
Match tasks to turn items apps/web/src/components/chat/ThreadActivityBanners.tsx
The UI matches a pending task to a turn item using nativeItemId, falling back to the task ID.

Update 2026-11-10: merged current github/main again (merge commit 963f5d0961, no rebase) to clear a conflict in ClaudeAdapterV2.test.ts. Main's #33647 added command/itemId to pending background tasks; the resolution keeps both its details assertions and this PR's moved-foreground case. The PR's own diff is unchanged. Blacksmith vp run check:changed passes on the new head: format, lint, knip, typecheck of 37 packages, 361 adjacent tests, React compiler coverage. No new review findings.
Thanks SunkenInTime. Your task-id to tool-call-id mapping fixes the missing elapsed time without changing task lifecycle ids. I preserved all four commits and merged current github/main into the original branch at 814f9c9dcd48c59dce8c203229fb1faca22e5fe1. The fix remains five files, +92/-11; no implementation pieces were dropped or moved.
Verification: the existing regression fails on main because nativeItemId is undefined. All 292 Claude adapter and SDK replay tests pass with the fix. Blacksmith vp run check:changed passes format, lint, knip, typecheck of 32 packages, adjacent tests, and React compiler coverage. Two independent code reviews found no blocking issues. All GitHub checks are now green on this exact head (CLEAN); CodeRabbit completed successfully. GitCafe still reports the previous head da000cf and has not mirrored this comment to GitHub, so its status is stale.
Client evidence below uses matching isolated fixture data and the actual main/fixed banner components. It verifies the client timestamp lookup, not a live Claude command. Live Claude execution and Stop against a real command remain unverified here because Claude is not authenticated. Desktop uses this same web component; mobile has no elapsed-time display today.
Known low limits: the bounded cache can omit a timestamp for a foreground task if 64 newer live tasks evict its link before it backgrounds. The existing long-running monitor test does not force that eviction path. Neither limit changes command execution or stopping.

installed and ran github/main at 616c426f5f199865e34974777740dff678ffb7f5 in /home/user/main, then stopped its captured process group before running this pr's exact head 814f9c9dcd48c59dce8c203229fb1faca22e5fe1 in /home/user/t3code. ran vp i in both. each background dev server used separate empty state with seeding disabled. main used web/server ports 8693/16733; the pr used 5733/13773.
used the repo's playwright with /usr/bin/google-chrome. created a project through the app pointing at a real git repository, then submitted real codex gpt-6.1-sol turns through the composer. no mocked provider events, demo data, or injected task records were used for this runtime pass.
neighboring behavior: on both checkouts, a real sleep 180 returned a running execution session, the background line displayed elapsed time, and clicking stop terminated the command before 180 seconds. the pr recording shows the timer increasing from 1m 44s to 1m 50s, then stopping and disappearing. provider logs confirm termination at 110.656 seconds with exit code -1. a subsequent real tool turn ran printf verification-followup-ok, exited 0, and displayed its response in the same thread.
the initial provider items required a thread reload to appear on both checkouts. after that, the timer and stop state updated live. this was also observed on main, so this pass does not attribute it to this pr.
supplemental automated checks on blacksmith: the existing ClaudeAdapterV2.test.ts and ClaudeReplayFixtures.integration.test.ts suites passed, 292/292 tests. these replay/unit checks are not live claude evidence. existing github ci checks pass on the tested head.

claude auth status: loggedIn=false, authMethod=none
the original claude bug on main and its fix on this pr. both running apps report claude v2.1.314: not authenticated; claude auth status confirms no authentication. codex uses different task ids and cannot prove claude's task_id to tool_use_id mapping. authenticating claude and running a real background bash command on both revisions is still required before calling this fix runtime-verified.
live claude task completion, foreground-to-background transitions, monitors, and task-link retention under concurrency.
native ios/android, electron desktop, macos/windows, remote relay/tunnel, and multiple clients. this pass exercised the local linux web client only.
Run sleep 900 in Claude Bash with run_in_background: true, let Claude finish replying, inspect the single pending background command for several seconds, then click Stop.
