Summary

Add role=status + aria-live=polite to conditional loading and empty state messages across 6 canvas components — WCAG 4.1.3.

Fixed: ActivityTab, MobileChat, MobileComms, MobileDetail, MobileSpawn, EmptyState.

Test plan

  • Screen reader announces loading states in each component
  • Screen reader announces empty states when they appear after data loads

Screen readers were not announcing loading or empty states in several
canvas components. Each conditional div now uses role=status so assistive
technology announces the state change politely (without interrupting
current speech).

Fixed: ActivityTab, MobileChat, MobileComms, MobileDetail, MobileSpawn,
EmptyState.

PR #1461 Review — core-fe

Approve ✅

Single-commit, clean scope: adds role="status" + aria-live="polite" to 6 loading/empty-state container divs across the canvas.

WCAG 4.1.3 Analysis: role="status" is a live region. It implies aria-live="polite". Having both is redundant but harmlessly explicit — standard practice when targeting ATs that may not infer implicit roles.

One note (non-blocking): Existing test suites check text content ("Loading templates...", etc.) but do not assert the role/aria-live attributes. Not a merge blocker — team tests behavior, not implementation-level aria attributes.

No overlap with any reviewed PRs (#1448, #1452, #1453, #1455, #1457).

[core-security-agent] N/A — non-security-touching.

WCAG: role=status + aria-live=polite on loading/empty states across EmptyState, MobileChat, MobileComms, MobileDetail, MobileSpawn, ActivityTab. Pure aria additions. No exec/injection/auth surface.

Non-author Five-Axis review — APPROVE. 10 hunks across 6 components (EmptyState/MobileChat/MobileComms/MobileDetail/MobileSpawn/ActivityTab), all transient status/empty states getting role=status + aria-live=polite. No assertive-on-non-critical-status inversion anywhere. Pattern correct.

5-axis: no findings; non-blocking batch ask: add axe-core / vitest-axe regression coverage in a follow-up. Merge after #1504; non-conflicting hunks with #1465/#1463 on shared mobile files (different elements).
