Closes #2591

PR type: New feature — type:feature

Summary

• Fullscreen sidebar gives background jobs their own collapsible rail card (⧗ Jobs) between Status and Agents: one row per running job with its label and elapsed time, newest first, painting nothing while no job runs; the Status card no longer repeats them.
• The card collapses like Agents and Todos — clickable header, ctrl+shift+j (GENTLE_PI_JOBS_KEY to remap or disable) — and the rail order becomes Status → Jobs → Agents → TODO.
• Finished jobs linger for 60 seconds (newest 3) with ✓ / ✗ / – result glyphs and their elapsed frozen at the end, then the card clears itself; the jobs snapshot carries optional status/endedAt/exitCode, so older publishers keep validating.

Changes

File	Change
lib/jobs-widget.ts	New: the Jobs rail card renderer (rows, result glyphs, 60s finished tail, collapse control)
lib/jobs-sidebar-state.ts	RunningJobDisplay gains optional status/endedAt/exitCode with validation; jobsCollapseKey helper
lib/shell-sidebar-layout.ts	Rail sections: footer → jobs → agents → todo
lib/shell-bar.ts	Status card drops its Jobs group (the jobs card owns it now); compact bar keeps the count
extensions/gentle-shell.ts	Registers the jobs rail part: hover/click collapse on the header, self-clearing 1s frame loop, ctrl+shift+j shortcut
extensions/gentle-agents.ts	refreshJobStatus publishes the running list plus the 60s finished tail (cap 3); status-key count stays running-only
docs/gentle-shell.md	Documents the card, its shortcut, and the new rail order
tests/*	New jobs-widget suite; updated shell-bar, shell-sidebar-layout, gentle-shell, gentle-agents pins

Test plan

• Focused suites green: 689/689 (jobs-widget 10, gentle-shell 282, gentle-agents 268, shell-bar 60, shell-sidebar-layout 49, background-jobs 13, jobs-view 7)
• Typecheck clean: node scripts/check-types.mjs reports 0 diagnostics, no regressions
• Manually tested in a live fullscreen shell: card appears between Status and Agents, elapsed ticks per second, header click and ctrl+shift+j collapse/expand, finished ✓ tail lingers then clears
• shellcheck: no shell scripts modified
• Docs updated (docs/gentle-shell.md)

Checklist

• Linked an approved issue (feat(shell): give running background jobs their own collapsible sidebar card #2591 carries status:approved)
• Added exactly one type:* label (type:feature)
• Conventional commits (feat(sidebar): …), no Co-Authored-By trailers
• Branch updated from main (release 4.4.0)

Summary by CodeRabbit

• New Features
  • Added a Jobs sidebar card showing running jobs and up to three of the newest recently finished jobs, with status and elapsed time. Finished jobs remain visible for up to 60 seconds.
  • Collapse or expand the card using its header control or keyboard shortcut. The card appears at widths of 140 columns or more.
  • Updated the fullscreen sidebar order to Status → Jobs → Agents → TODO.
• Updates
  • Job details now appear in the Jobs card rather than the Status card; the compact sidebar retains the running-job count.

Walkthrough

The fullscreen sidebar now has a dedicated, collapsible Jobs card. It displays running jobs and eligible recently finished jobs, while the Status card no longer lists job descriptions.

Changes: Jobs sidebar card

Layer / File(s)	Summary
Job snapshot data and retention lib/jobs-sidebar-state.ts, extensions/gentle-agents.ts, tests/gentle-agents.test.ts	Job snapshots support finished-job status, end time, and exit code. The snapshot producer includes eligible recently finished jobs alongside running jobs.
Jobs card rendering and sidebar interaction lib/jobs-widget.ts, extensions/gentle-shell.ts, tests/jobs-widget.test.ts, tests/gentle-shell.test.ts	The card sorts and renders running and recently finished jobs, shows elapsed time and outcome glyphs, and supports collapse controls. The shell sidebar handles snapshot data, redraws, and disposal.
Rail placement and Status separation lib/shell-sidebar-layout.ts, lib/shell-bar.ts, docs/gentle-shell.md, tests/shell-sidebar-layout.test.ts, tests/shell-bar.test.ts	The fullscreen rail places Jobs between Status and Agents. Job descriptions are removed from Status, and the documentation describes the card and its controls.

Full details: Linked Issues check

Explanation

Issue #2591 coding requirements are met at head 5518c48.

Jobs card rendering: lib/jobs-widget.ts renderJobsCard draws one row per job. widgetJobs sorts running jobs by startedAt descending. It returns an empty array when no jobs are shown, so the card paints nothing.

Finished tail: widgetJobs keeps finished jobs only when now - endedAt < JOBS_FINISHED_TTL_MS (60_000). It sorts them by endedAt descending and caps them at 3 (MAX_FINISHED). glyph() maps stopped to –, failed to ✗, and exited to ✓ or ✗ by exit code. Elapsed time uses job.endedAt for finished jobs, so it freezes.

Rail placement: lib/shell-sidebar-layout.ts builds sections as footer, jobs, agents, todo. The rail mounts only in fullscreen at SIDEBAR_BREAKPOINT (140) or wider. The 140-column requirement is inherited from that gate.

Collapse: extensions/gentle-shell.ts registers a header click handler that toggles jobsCollapsed. It also registers a shortcut from jobsCollapseKey(env). The default key is ctrl+shift+j, and GENTLE_PI_JOBS_KEY can remap or disable it (per the PR description and lib/jobs-sidebar-state.ts summary).

Status card and compact count: extensions/gentle-shell.ts passes the Status input jobs as running-only (status === undefined). The compact hidden-Status row uses the running-only list. The Jobs group is removed from lib/shell-bar.ts per the change summary.

Snapshot: RunningJobDisplay carries optional status, endedAt, and exitCode. These are forwarded from the snapshot in gentle-shell.ts.

Limits of evidence: I read lib/jobs-widget.ts, the whole-PR diff of extensions/gentle-shell.ts, and lib/shell-sidebar-layout.ts (truncated, but the section order line is visible). I did not re-read lib/shell-bar.ts, lib/jobs-sidebar-state.ts, or extensions/gentle-agents.ts directly. Those findings rely on the change summary. The test counts are author-reported and were not re-run.

Full details: Out of Scope Changes check

Explanation

All changes relate to Issue #2591.

New code: lib/jobs-widget.ts implements the card. lib/jobs-sidebar-state.ts adds the optional status fields, snapshot validation, and jobsCollapseKey. lib/shell-sidebar-layout.ts adds the jobs rail section. lib/shell-bar.ts removes the Status Jobs group that the issue says repeats the jobs.

Supporting changes: extensions/gentle-shell.ts wires the rail part, the hover and click collapse, the 1s redraw timer, the shortcut, and running-only compact input. extensions/gentle-agents.ts publishes the finished tail with the same 60s TTL, which the card needs.

Documentation and tests: docs/gentle-shell.md documents the card, the shortcut, and the rail order. The tests cover the new card, the updated pins, and the validator cases. These support the requested behavior.

No unrelated change was found. The NativePointerRegion import is used for the card hit handling. The prior review's out-of-scope conclusion still holds for the changed code. The incremental changes since the previous reviewed heads add only the finished-tail, running-only count, and test coverage paths already described above.

Full details: Docstring Coverage

Explanation

Docstring coverage is 35.71% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 14 functions across 11 files. (1 skipped: 1 unsupported.)

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

Pass the running-job projection to createShellBarComponent.

The fullscreen footer receives running jobs, but the regular compact component does not. Its model therefore has no jobs value, so regular mode omits the ⧗ N jobs count.
