Background commands can outlive a turn, but the background-work banner has no action to inspect their full command.

Add an always-available Details action showing the task description, command, Running/Waiting state, existing captured output when available, and subagent navigation. Claude tasks retain their launching command and source item across roster snapshots. Explicit item IDs take precedence over native IDs. Internal task IDs, repeated command labels, and the empty output heading stay out of the dialog.

Validation: vp run check:changed passes with 371 tests. The browser regression covers conflicting native IDs, native fallback, current task details, and dialog dismissal. The Claude adapter regression covers command metadata surviving roster snapshots. A fresh Codex Luna run confirmed the final dialog visually; earlier Claude Haiku testing confirmed its command details.

Output collection follows existing provider support. Claude's completed launch receipt is hidden; this change does not collect its background stdout or add exit-code display. Antigravity's existing command inspector was exercised, but its background Details path was not verified. Grok could not run because its CLI is absent in the test environment.

Implemented and verified with GPT 6.1 Sol in the Codex harness.

Visual verification

Before: an isolated UI fixture shows the background banner without an inspection action.

After: a real Codex Luna command in the final Details dialog, with one command block, no internal task ID, and no empty output heading.

Approvability

Verdict: Approved at a0326ab

Macroscope's review found this PR approvable — Adds a Details dialog for background commands and subagents, backed by retained task metadata and existing output streaming. Command execution, permissions, and product defaults remain unchanged.

Walkthrough

The Claude adapter associates pending background tasks with matching command calls and preserves those details across roster updates. The chat UI adds a dialog that displays task status, commands, captured output, and subagent thread actions.

Changes: Background task details

Layer / File(s)	Summary
Task data and command association packages/contracts/src/orchestrationV2.ts, apps/server/src/orchestration-v2/Adapters/ClaudeAdapterV2.ts, apps/server/src/orchestration-v2/Adapters/ClaudeAdapterV2.test.ts	Pending task data can include the command, turn-item ID, and source thread ID. The adapter adds these fields when a background task matches a command call and merges prior task fields into refreshed roster entries. The test checks that command details persist across a roster snapshot.

For running matched items, it can display captured output. Subagent tasks with a child thread ID can open that thread. Browser tests cover descriptions, output visibility, and dialog dismissal.

Track background output for the task lifetime

For a directly backgrounded Claude Bash command, the launch result completes the item while the task is still running. The adapter skips its tail, the hub ends item subscriptions on settlement, and the dialog removes the panel. Users cannot follow continuing output in Details.

Connect output to the background task’s lifetime through the adapter, hub, and dialog, while preserving normal launch-item settlement and cleanup.

Note

Generated by GPT 6.1 Sol

Verified the outside-diff Claude-output finding against the base and this head. The adapter already excludes directly backgrounded Bash calls from its output tail, and the existing output hub ends subscriptions when the launching item settles. This PR does not change those lifetimes.

The current scope is inspecting the full command and task state, with existing captured output when available. The description explicitly records that Claude background stdout collection and exit-code display are not added. Implementing task-lifetime output collection would expand the change across the adapter, output hub, and UI, so I am deferring that recommendation from this PR. The existing launch receipt stays hidden and launch-item settlement remains intact.

The earlier item-ID matching finding is fixed and its thread is resolved. Before/after screenshots are now included in the PR description.
