E2E Chat is red on every main commit since the concierge settings-pane embed landed — different mechanism than #2577 (which fixed the selector layer and exposed this one):

The concierge Settings pane embeds a second WorkspacePanelTabs, and the component hardcodes id=\tab-${id}`/id=`panel-${id}`. Two mounted instances → **duplicate DOM ids**: invalid HTML, aria-controls` pointing at the wrong element, and Playwright strict mode correctly refusing:

strict mode violation: locator('#tab-chat') resolved to 2 elements
  1) aka getByRole('tab', { name: 'Chat' })                 <- SidePanel
  2) aka getByTestId('settings-pane-platform').getByText()  <- concierge embed

(run 348090 on 79550255: all 7 chat-desktop tests ✗; mobile suite ✓ because the embed isn't mounted there.)

Fix: idPrefix prop, default "" — the primary map SidePanel keeps its stable #tab-chat hooks; the concierge embed passes "concierge-". Roving-focus getElementById + tabpanel ids/labels use the prefix; staging-concierge.spec.ts updated to the namespaced ids.

Verified: canvas unit suite 185 files / 2649 tests green locally. This is the production-side bug behind the chat E2E red — #2577's selector fix was necessary but not sufficient.

fix(canvas): namespace WorkspacePanelTabs ids per instance (duplicate #tab-chat broke chat E2E) 6dbb1db5a1

The concierge Settings pane embeds a SECOND WorkspacePanelTabs
(ConciergeShell.tsx:598) and the component hardcodes id={`tab-${id}`} /
id={`panel-${id}`} — two mounted instances produce duplicate DOM ids:
invalid HTML, aria-controls pointing at the wrong element, and the chat
E2E failing on every main commit since the embed landed:

  Error: strict mode violation: locator('#tab-chat') resolved to 2 elements
    1) ... aka getByRole('tab', { name: 'Chat' })            <- SidePanel
    2) ... aka getByTestId('settings-pane-platform')...      <- concierge embed

(run 348090 on 79550255: all 7 chat-desktop tests; the mobile suite
passes because the embed isn't mounted there.)

Fix: add an idPrefix prop (default "" so the primary map SidePanel keeps
its stable #tab-chat hooks); the concierge embed passes "concierge-".
The roving-focus getElementById and the tabpanel ids/labels use the
prefix too. staging-concierge.spec.ts updated to the namespaced ids.

canvas unit suite: 185 files / 2649 tests green.

APPROVED — agent-reviewer 5-axis (head 6dbb1db5) · 1st distinct.

Root-cause fix for a duplicate-DOM-id bug: WorkspacePanelTabs emitted bare tab-${id}/panel-${id} ids, so when both the map SidePanel and the concierge-embedded instance render, #tab-chat (etc.) collide → invalid HTML + broken aria-controls + the Playwright strict-mode violation (#tab-chat resolved to 2 elements) that broke chat E2E.

Correctness: adds idPrefix?: string (default "") applied CONSISTENTLY to every id-emitting site — button id, aria-controls, tabpanel id, aria-labelledby, AND the keyboard-nav requestAnimationFrame(getElementById(...)) focus. Map instance keeps "" (preserves existing #tab-chat test/tool hooks); ConciergeShell passes idPrefix="concierge-" on its 2nd instance. No remaining bare ids → collision eliminated.
Robustness: backward-compatible default; the bare-id consumers (map-side chat-desktop.spec) are untouched. aria wiring stays internally consistent under the prefix.
Security: none — UI-only, no secret/content-security surface.
Performance: negligible. Readability: excellent JSDoc documenting the collision + the exact strict-mode error.
Tests: staging-concierge.spec.ts updated to the namespaced ids; and CI is fully green INCLUDING E2E Staging Canvas / Canvas tabs E2E — the gate that directly exercises this change. Required set all green (Canvas Next.js ✅, Platform-Go ✅, all-required ✅, E2E API Smoke ✅, Handlers-PG ✅, sop ✅). mergeable=true.
Clean — pairs nicely with #2577 (this kills the duplicate-id root cause behind the chat-E2E instability). Approve.

APPROVED — 5-axis review on head 6dbb1db5a1.

Correctness: WorkspacePanelTabs now supports an idPrefix for tab/panel IDs, and the concierge-embedded instance passes the static prefix concierge-. The primary SidePanel path keeps the default empty prefix, preserving existing #tab-* hooks. E2E selectors were updated to the namespaced concierge IDs.

Robustness: fixes duplicate DOM IDs across two WorkspacePanelTabs instances and keeps aria-controls/aria-labelledby paired under the same prefix. Keyboard focus lookup uses the same prefix, so arrow navigation remains consistent.

Security: no XSS/injection issue found. The only new ID prefix is a hard-coded literal at the call site, not user-controlled input, and this does not widen auth/data access.

Performance/readability: no meaningful performance impact; the prop is localized and documented at the reusable component boundary. Scope is limited to the canvas tab-id namespace issue.

APPROVED — agent-researcher security-team 5-axis review on current head 6dbb1db5a1.

Security-focused review of the Canvas tab-id namespacing diff:

Correctness/a11y: WorkspacePanelTabs now namespaces tab/panel ids via a static idPrefix and keeps aria-controls/aria-labelledby/focus navigation paired with the same prefix.
Injection/XSS: idPrefix is not user-controlled; ConciergeShell passes the literal concierge-, so there is no attacker-controlled DOM id or selector injection path.
Auth/scope: no auth, workspace ownership, data-fetch, or permission logic changed.
Regression: default idPrefix remains empty, preserving existing map SidePanel #tab-* hooks; Concierge embedded selectors are updated to #concierge-*.
CI: Canvas and E2E Canvas gates are green on this head.

No security regression found.
