What

Settings → Appearance gains Group agents by state (off by default, kept on this device like the sidebar filter). When on:

• The Agents list moves above the workspaces.
• Its unpinned rows split into Needs you (blocked), Working (BG included), Done (a finish not read yet) and Idle (ready, an already read finish, an unknown state, or a PC that is away). Empty groups are left out; each group has a quiet caps heading with its count.
• Within a state orders each group: Longest wait (default; the oldest state_change_seq first, Sidebar: a Longest wait order for the Agents list #2015), Recent or Name. herdr's counters only compare within one PC, so Longest wait and Recent order each PC's rows (PCs in list order); Name orders across PCs.
• Pinned agents stay first, as before. An agent and its helpers stay together, in the group of the one that needs the reader most (a blocked helper brings its agent into Needs you).

Also: an agent kind without a logo of its own now draws its initial in a disc tinted by its kind (one of the theme's --term-* colors, picked from the kind name). Agent logos → Mono keeps the disc quiet.

The shared Agents order setting (Workspaces / Activity) is unchanged and applies while grouping is off. Default UI is unchanged.

Design reference: group headings follow Slack's sidebar sections (caps heading, count trailing); the Longest wait order follows herdr's own agent view sort by state_change_seq ascending, as #2015 describes.

Closes #2015

Screenshots

Before/after at 390 and 1280, dark and light, plus the Settings rows, were attached for review in the lane report (demo fixtures).

Validation

• bun run check fast (heavy runner)
• Focused: bun test src/lib/agentRoster.test.ts src/lib/settings.test.ts src/lib/i18n.test.ts src/conventions.test.ts scripts/changelog-fold.test.ts, bun run typecheck
• New grouping tests were seen failing against a deliberately broken sort and family rule, then passing.
• Manual: demo build at 390/1280, dark/light, grouped and default.

Summary

Summary by CodeRabbit

• New Features
  • Added an optional, device-local setting to group agents above workspaces by state: Needs you, Working, Done, and Idle. Pinned agents remain at the top, and empty groups are hidden.
  • Choose how agents are ordered within each group: Longest wait, Recent, or Name.
  • Agents without a custom mark now display a kind-tinted initial; the Mono logo setting suppresses this mark.

The change adds device-local agent grouping by state, sort controls, sidebar group headings and counts, and kind-tinted fallback marks for agents without logos.

Full details: Title check

Explanation

The title "feat(sidebar): group the Agents list by state, ordered by longest wait, recent or name" matches the main change: a device-local setting that groups unpinned agent rows into Needs you, Working, Done, and Idle, with Longest wait, Recent, or Name ordering inside groups. It is a single, specific sentence. It is slightly long at 86 characters, but it stays clear and readable.

Full details: Description check

Explanation

The description follows the template. The What section states the problem and the resulting behavior, and it links the issue (#2015). The Validation section lists the commands run, the focused test files, the typecheck, and the manual checks. It does not list any skipped checks or state whether HTTP/WS contract tests apply, which the template asks for. These gaps are minor.

Full details: Linked Issues check

Explanation

#2015 requires Longest wait as a third value of the existing Agents order setting, with Workspaces still the default. The reviewed code adds a separate agentGroups setting and applies agentGroupSort: "wait" only when grouping is enabled. Therefore the requested order is not available through the existing Agents order setting. The required priority is also not preserved: groupAgentRows orders groups as blocked, working, done, idle, while #2015 requires blocked, unread Done, ready, working, and unknown.

Resolution

Add Longest wait to the existing agentOrder setting. Keep Workspaces as the default. Apply pinned-first ordering, then the #2015 status priority, then oldest state_change_seq within each PC with herdr order as the tie-breaker.

Full details: Out of Scope Changes check

Explanation

The kind-tinted fallback discs in AgentMark.tsx and AgentMark.css have no connection to #2015, which covers Agents-list ordering. The PR also adds unrelated Name and Recent group sorting and a new grouping preference beyond the linked issue's requested existing setting.

Resolution

Remove changes that are not required to implement #2015, including the kind-tinted fallback-disc feature, or link those changes to a separate active issue with matching coding requirements.

Full details: Docstring Coverage

Docstring coverage is 76.92% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 13 functions across 20 files.

Review round (omo + Codex Terra) on 9575a3b, and what changed:

1. MEDIUM, reproduced (omo + Codex): each state group was its own <ul>, so a row whose state changed (working -> blocked, or an unread Done read -> Idle) was drawn anew in another list: keyboard focus fell away and an open row menu closed. Fixed in d55f4e7: the grouped rows and their aria-hidden headings are one list, so React moves the row. d93129a adds a sidebar render test for it.
2. MEDIUM (Codex), confirmed by grep: dark themes do not set --term-red ... --term-cyan, so the fallback mark tint was invalid there. Fixed in d55f4e7: the tint uses the --syntax-* tokens that every theme sets in both modes (checked by screenshot in dark and light).
3. LOW, unreproduced (omo), left as is: a herdr-core snapshot carries no state_change_seq, so Longest wait and Recent fall back to the list order there. The existing Activity order has the same limit on main.

CodeRabbit hit its review limit on this PR.

Minor · Performance & Scalability · Quick win

Pass the row index to familyRows instead of scanning for it.

groupAgentRows calls familyRows once for each row that opens a family. familyRows then calls nested.indexOf(start), which scans from the start of the array. For a large set of independent agents, every row opens a family, so the total scan cost grows with the square of the row count. The grouping memo in AgentSidebar.tsx recomputes whenever activity changes, so this cost recurs on each recomputation. At typical roster sizes the added time is small, so this is a minor performance issue.

Assert that the grouped row keeps its instance across the state change.

The test name says the row moves to its new group without being drawn again. Its assertions read only the group heading before each data-pane row, so a row that remounts inside the same list still passes. react-test-renderer has no DOM focus, so instance identity is the observable check. Capture the row before the update and assert that the same instance is returned after it.

🧪 Suggested test change

     expect(groupOf(paneId)).toBe("working");
+    const rowBefore = mounted.root.findByProps({ "data-pane": paneId });
     // When the agent becomes blocked, its row is still a child of the same list, now under Needs you.
     await act(async () => { mounted.update(grouped(blockedRoster(true))); });
     expect(groupOf(paneId)).toBe("blocked");
+    expect(mounted.root.findByProps({ "data-pane": paneId })).toBe(rowBefore);
     expect(mounted.root.findAllByProps({ className: "agent-list" })).toHaveLength(0);

- Line 28: Reduce the tint applied by the fill rule in `.agent-mark
.agent-mark-disc` so the inherited `--text` initial maintains at least 4.5:1
contrast in solarized-light and tokyo-night-day, while preserving the syntax-hue
tint.

Review comments at @src/components/AgentSidebar.tsx:
- Around line 198-203: Update the `groups` useMemo in `AgentSidebar` to order
its input by herdr’s roster order before passing it to `groupAgentRows`, so
grouped row tie-breaking is independent of the Agents order setting. Preserve
the existing grouping options and dependencies, and use the established
roster-order source rather than deriving order from Activity-sorted
`split.rest`.
