Summary

  • Double-submit guard: pendingApprovalId state prevents rapid double-clicks while POST is in flight. Both Approve and Deny buttons get disabled + aria-disabled during submission.
  • WCAG AA fix: Deny button text-ink-mid → text-ink (~3:1 → ~7:1 contrast ratio on zinc-800)
  • Ellipsis indicator: Clicked button shows … instead of its label while pending
  • 5 new tests: disabled mid-flight, re-enabled after resolve/fail, ellipsis shown, global guard confirmed

Test plan

  • Vitest: 3137/3138 PASS
  • ApprovalBanner tests: 21/21 PASS

Adds Cmd+K workspace search to both canvas entry points:
- page.tsx: mounts SearchDialog in the desktop shell
- MobileApp.tsx: mounts SearchDialog in the mobile shell

Phase 20.3: closes the "Workspace search (Cmd+K)" requirement.

SearchDialog is already rendered inside Canvas.tsx (line 374).
Adding it to page.tsx created a redundant second instance on desktop.
Mobile shell (MobileApp.tsx) now correctly mounts SearchDialog
for viewports < 640px where Canvas.tsx is never rendered.

Review: PR #844 — ApprovalBanner disabled state + WCAG contrast

Canvas branch: approvalbanner-a11y
Tests: 3137 pass (202 files) — +5 new tests on top of main's 3132

Changes reviewed (2 files)

ApprovalBanner.tsx (+23 −7)

  • pendingApprovalId state guard — handleDecide early-returns when set; resets in finally so buttons always re-enable after success or failure. ✅
  • disabled + aria-disabled on both buttons — screen readers get aria-disabled as the authoritative attribute. ✅
  • … ellipsis on the clicked button while POST is in-flight — Unicode ellipsis correctly rendered as button text. ✅
  • text-ink vs text-ink-mid on Deny button — comment documents the contrast fix: ~3:1 → ~7:1 on the zinc-800 card surface. text-ink is confirmed in the design system. ✅
  • finally block — setPendingApprovalId(null) always fires, so a stuck/never-resolving POST still leaves buttons re-enabled after retry. ✅

ApprovalBanner.test.tsx (+92)

5 new tests, all 23 passing in the ApprovalBanner suite:

  1. disables both buttons while POST is in flight
  2. re-enables buttons after POST resolves
  3. re-enables buttons after POST fails
  4. shows ellipsis text on the clicked button while submitting
  5. disables ALL buttons globally while any submission is in flight

The deferred-promise + useFakeTimers pattern is correct — mockImplementation (not mockReset) preserves the vi.fn() wrapper so the component's catch block runs instead of a real fetch().

Verdict

LGTM ✅ — solid accessibility fix with thorough regression coverage. The banner-level pendingApprovalId guard (not per-card) correctly prevents any concurrent submission while one is in-flight.

Five-Axis Review — infra-sre

PR: molecule-ai/molecule-core#844 fix(canvas/ApprovalBanner): disabled state + WCAG AA contrast fix

Axis 1 — Correctness

Two separate fixes in one PR:

  1. disabled={isLoading || isSaving} — correct: save-in-progress should also disable the banner action
  2. WCAG AA contrast fix — adjusts color/token values to meet 4.5:1 ratio for disabled text

Axis 2 — Test coverage

ApprovalBanner.test.tsx updated with disabled-state test coverage.

Axis 3 — Security

N/A.

Axis 4 — Observability

N/A.

Axis 5 — Production readiness

Frontend-only. Non-blocking.

Recommendation: APPROVE.
