Tabs fit and finish, plus editing the roster and tabs from the settings modal

Follow-up to #3. The tab strip becomes real tabs above the content, codeowners tabs keep a usable sidebar, two filter-reset bugs go away, and the settings modal can now edit both board.members and board.tabs instead of pointing at places that could not.

What changed

Tab strip (TabBar.tsx, Board.tsx, style.css)

  • Moves tabs out of the controls row into a role="tablist" strip above the grouped content
  • Tab buttons carry a surface color; the strip itself stays on the page background
  • Sidebar and content transition over 150-200ms instead of snapping when a tab hides the roster card

Codeowners tabs keep a roster (data.ts, view.ts, Sidebar.tsx)

  • inferRoster builds the sidebar from the queue's authors, with a note saying so, so author filtering still works
  • rosterUsernamesFor re-validates the author filter against the active tab's roster on poll and first load; before, a codeowners-tab filter snapped back to "all" a second later

Roster editor (ConfigModal.tsx, config.ts, server.ts)

  • RosterControl on the board.members row: add by username, drop with an armed confirm
  • POST /roster validates (dupe, unknown, last member, defaultMember), persists through the ownership latch via saveRosterMembers, swaps the in-memory roster, invalidates the snapshot

Tabs editor (ConfigModal.tsx, config-shapes.ts, config.ts, server.ts)

  • TabsControl on the board.tabs row: rename, edit a codeowners tab's section and hide-roster-authors flag, per-tab slack channel and review skill, add (id slugged from the label), drop with an armed confirm; the last tab is undroppable
  • POST /tabs validates with parseTabs, persists via saveTabs (same latch rules as the roster, including the no-config.json ownership ruling), swaps config.tabs, invalidates the snapshot so the next fetch declares the new sections to rt
  • matchesShape gains a tabs case mirroring parseTabs, so the modal flags a malformed store value instead of rendering an editor over it

Follow-up

  • Registry descriptions for board.members, board.ticketPrefixes, board.slack still read as a one-tab world; that reword lives in rt's registry-defs.ts and ships with the next rt-client

Checklist

  • Anything that should be behind a feature flag is behind a feature flag
    • N/A. The strip and editors render only when the config already has them
  • Appropriate tests have been created or updated
    • saveTabs latch cases, tabs shape + slugTabId, inferRoster, rosterUsernamesFor; suite 801/801 green, typecheck clean

- TabBar moves out of the controls row into a real tab strip above the
  grouped content; tab buttons carry a surface color, the strip does not
- sidebar and content transition (150-200ms) instead of snapping when a
  codeowners tab hides the roster card
- codeowners tabs get a roster inferred from the queue's authors so the
  sidebar (and author filtering) stays reachable; a note says where it
  comes from
- author filter no longer resets on poll or first load for codeowners
  tabs: re-validation uses the tab's own roster, not board.members
- roster editing lives on the board.members row of the settings modal
  (RosterControl) via POST /roster, which honors the ownership latch,
  refuses to drop the last member or defaultMember, and swaps the
  in-memory roster so /data.json agrees immediately

TabsControl on the board.tabs row: rename tabs, edit a codeowners tab's
section and hide-roster-authors flag, set per-tab slack channel and
review skill, add a tab (id slugged from the label), drop a tab with an
armed confirm; the last tab cannot be dropped. Writes go through
POST /tabs, which validates with parseTabs, persists through the
ownership latch (saveTabs), swaps config.tabs, and invalidates the
snapshot so the next fetch declares the new sections to rt.

📝 Walkthrough

Walkthrough

The board now supports configurable tabs and roster editing. It adds tab-aware member validation, inferred codeowners rosters, persistence endpoints, configuration controls, and tests for validation, slugging, state resolution, and file- or store-backed writes.

Changes

Tabs and roster management

Layer / File(s) Summary
Tab contracts and roster derivation
src/client/board/config-shapes.ts, src/config.ts, src/data.ts, src/view.ts, src/__tests__/board.test.ts, src/__tests__/view.test.ts, src/client/__tests__/config-shapes.test.ts
Tab values use composite-shape validation and generated IDs. Roster inference and tab-specific username resolution are covered by tests.
Roster and tab persistence APIs
src/config.ts, src/server.ts, src/__tests__/config-store-latch.test.ts
Roster and tab updates use store-backed or atomic file-backed persistence. New endpoints validate requests, update memory, invalidate snapshots, and return errors.
Tab-aware board rendering
src/client/board/Board.tsx, src/client/board/TabBar.tsx, src/client/board/Sidebar.tsx, src/client/board/Controls.tsx, src/style.css
The board renders tabs, validates member state per tab, displays inferred codeowners rosters, and moves tab navigation into TabBar.
Server-backed configuration editors
src/client/board/ConfigModal.tsx, src/client/board/InfoTip.tsx, src/style.css
The configuration modal edits roster members and tab fields through /roster and /tabs. It displays contextual help and inheritance-aware tab fields.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟠 High · up to 4ed3b

This PR adds roster and tab editing, but non-local visitors can currently change those persisted settings, deleting the active tab can leave the board and review requests pointing at removed state, and rapid tab edits can overwrite earlier changes. These correctness and authorization risks should be fixed before merge.

476-484: 🚀 Performance & Scalability | 🔵 Trivial | ⚡ Quick win

Skip the snapshot read when the user is already on the roster.

taggedAuthor awaits cache.get() even when onRoster is already true. If the snapshot is cold, this makes a scoped 15s refresh wait for a full board fetch before it starts its own member fetch. Compute the tagged-author fallback only when the roster check fails.

♻️ Proposed refactor
         const onRoster = !!u && config.members.some((m) => m.username === u && !m.hidden);
-        const taggedAuthor = !!u && (await cache.get()).mrs.some(

455-469: 🗄️ Data Integrity & Integration | 🔵 Trivial | ⚡ Quick win

Hold busy until the refreshed tabs arrive, or the next edit reverts this one.

write sends a list derived from the tabs prop, and that prop only changes after onSaved triggers the parent refetch. setBusy(false) at Line 459 runs before onSaved() at Line 465, and the refetch resolves later. A user who edits a second field in that window sends a list built from the pre-write tabs, which silently drops the first edit.

Keep the control busy until the refreshed tabs prop lands, or track the pending list locally and derive each write from it.

♻️ Proposed refactor sketch
   const write = async (next: TabConfig[]) => {
     setBusy(true);
     setError(null);
     const res = await postAction("/tabs", { tabs: next });
-    setBusy(false);
     if (!res.ok) {
+      setBusy(false);
       setError(res.text || "could not save tabs");
       return false;
     }
     setArmed(null);
     onSaved();
     return true;
   };

Clear busy in an effect keyed on the incoming tabs prop so the next write always starts from the persisted list.

In `@src/client/board/Board.tsx`:
- Around line 115-119: Update the setState callback in the data refresh flow to
normalize prev.tab to d.tabs[0].id when the current tab no longer exists, then
validate prev.member using that normalized tab. Preserve valid tab selections
and existing member-reset behavior, while ensuring the returned state cannot
retain a deleted tab ID.
- Around line 520-529: Update the mobile drawer rendering around the
isCodeownersTab condition to include the Sidebar with the same roster,
rosterTotal, and queue-specific note already passed in the desktop rendering.
Preserve the existing active member, selection, settings, configuration, and
scopeUncovered handlers so mobile users can filter inferred authors
consistently.

In `@src/client/board/config-shapes.ts`:
- Around line 105-122: Update matchesShape’s "tabs" validation to reject empty
arrays and arrays containing duplicate tab IDs, matching parseTabs before
rendering the editor. Extend isTabLike or the surrounding tabs check using the
existing id field, and update the test that currently expects [] to be accepted.

In `@src/client/board/ConfigModal.tsx`:
- Around line 352-353: The member visibility logic should also honor each roster
member’s hidden flag, not only board.hiddenMembers. Update the roster processing
and checked-out badge conditions around roster, hiddenSet, and the affected
member rendering so records with hidden: true are included in the checked-out
set while preserving the existing string-list handling.

In `@src/server.ts`:
- Around line 608-654: Add the existing isLocalRequest locality check
immediately after the method validation in the /roster handler (src/server.ts,
lines 608-654) and /tabs handler (src/server.ts, lines 655-677), returning the
standard 403 forbidden response for non-local requests. Preserve existing
mutation and validation behavior, and follow the established
request-header/content-type handling needed by isLocalRequest.

In `@src/style.css`:
- Line 859: Update the color value in the .tui-modal-btn.danger rule from
currentColor to the Stylelint-required lowercase currentcolor keyword, leaving
the other declarations unchanged.

Every row's registry description (plus the roster and tabs caveats) now
lives behind an info glyph that reveals a tooltip on hover or focus, so
the list reads as keys and controls. The tabs editor gets one field per
row with an aligned label column, more padding per card, a wider modal,
and placeholders that say what an empty field inherits (the actual
board.slack channel for slack, the repo's skill for review skill).

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
The ✕ now opens a strip that warns the tab's section, channel, and
skill settings are discarded; the drop button enables only once the
label is typed back exactly, with a cancel beside it.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Rows whose control is a block of fields (slack, triage, workspaces,
cwds, rtRepos, the lists, roster, tabs) gain a chevron and a summary
of what is set; the body animates open over 180ms via grid rows, stays
mounted so drafts survive a collapse, and is inert while closed. Open
rows are remembered per browser.

Keep tab writes blocked until refreshed tabs are available.

TabsControl.write clears busy before onSaved completes. Board passes onTabsSaved={() => load()}, and /tabs replaces the complete tab list. A second edit can use stale tabs and overwrite the first edit. Await load() before clearing busy, or update local tabs from the save response.

- a tab dropped while active no longer lingers as the view's tab id
- the mobile drawer shows the inferred roster on codeowners tabs, as
  the desktop sidebar already did
- matchesShape rejects an empty tab list and duplicate ids, matching
  parseTabs, so the modal flags such a store value instead of editing
- the roster editor's "checked out" badge honors an inline hidden flag
  as well as the hiddenMembers overlay, like rosterSummary
- /roster and /tabs require a local request, like every action endpoint
- currentcolor keyword case

The chevron was the only trigger. The head is now a role=button row
(key name, summary, and the slack around them), with the info tip and
the clear button carved out via stopPropagation; Enter and Space work
on the focused head.

The kit card paints --panel, the modal's own surface, so the tip sat flush
with the row behind it. Now --fg on --bg with a shadow: a tooltip in
either theme.

The head is the trigger now; a one-line digest of the value next to it
was noise. summarizeShape and its tests go with it.

Roster and tabs lists sat flush with the --panel modal. The well is --bg
now, tab cards inside it are --panel, and the drop strip carries a
faint danger tint, so each layer reads as its own surface.

Same shape as the review modal: flex-column root with overflow hidden,
a scrolling body for the groups.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Same #1d1830 dark-indigo tile and #ff84ad accent pink as
/Applications/mattstack.app's own AppIcon.icns, so the board reads as
part of that family in a tab strip. The merge-branch glyph is
unchanged; the feature-branch stroke moves to a violet tint of the
tile color instead of the old saturated purple, to sit alongside pink
rather than compete with it.
