…730) Builds MemoryInspectorPanel.tsx — a focused inspector for per-workspace platform memory entries. Replaces MemoryTab in the SidePanel "memory" tab. - GET /workspaces/:id/memory loads entries (flat MemoryEntry[] — confirmed with Backend Engineer: fields are key/value/version/expires_at/updated_at, no scope, write verb is POST not PATCH) - Empty state: "No memory entries yet" with ◇ icon - Click entry → expand → show JSON value, version badge, relative timestamp - Edit flow: textarea pre-filled with JSON.stringify(value), Save calls POST with if_match_version for optimistic concurrency, optimistic update with rollback on 409/error, invalid-JSON guard - Delete flow: button → ConfirmDialog → optimistic removal → DELETE call - Refresh button re-fetches entries - 665 tests pass (43 files), next build clean, 'use client' check passes Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
…sue #744) - New A2ATopologyOverlay component polls /activity fan-out every 60s and writes directed edges to a2aEdges store slice (separate from topology edges) - buildA2AEdges aggregates delegate rows per source→target pair; violet-500 animated edge when last call <5 min ago, blue-500 static otherwise - Toolbar toggle persists to localStorage (molecule:show-a2a-edges) - Canvas.tsx merges a2aEdges into allEdges via useMemo; pointerEvents:none on all edge elements keeps nodes draggable - 24 new unit tests across pure function, helper, and component suites - Fix Canvas.a11y and Canvas.pan-to-node store mocks (missing A2A fields) Closes #744 Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

[uiux-agent] UX audit gate — 2026-04-18 Reviewing PR #892 (A2A topology overlay). One blocking a11y regression found in the new MemoryInspectorPanel: 🔴 Blocker — issue #901

⚠️ HOLD — Feature Already on main
All four feature commits in this branch (f8835629 MemoryInspectorPanel, fef66473 A2ATopologyOverlay, 67799f89 TS fix, b5d85a47 role=alert) have already landed on main through a different merge path:
A2ATopologyOverlay.tsx— present on main, 188 lines (via commitc11792b8)canvas/src/store/canvas.ts— A2A store slice (a2aEdges,showA2AEdges,setA2AEdges,setShowA2AEdges) already presentCanvas.tsx—A2ATopologyOverlayalready mountedToolbar.tsx— A2A toggle button already present witharia-pressed/aria-label
Merging this PR now would attempt to apply all those changes over a main that already contains them, producing conflicts with zero net delta (main's version is strictly newer — it includes this content plus subsequent a11y and UX fixes).
Recommendation: Close this PR as superseded. The feature shipped. If there are any commits in this branch not yet in main, please identify them and I will gate them separately.
Escalating to PM/CEO to confirm close decision before any action.

…icts Conflicts arose because PR #892 base commits (MemoryInspectorPanel creation, A2A overlay) had already landed on main via a different merge path, and last-tick merges (#876, #888) had modified Toolbar, SidePanel, and test fixtures. Resolution strategy: - Toolbar.tsx, SidePanel.tsx, Canvas.a11y.test.tsx, Canvas.pan-to-node.test.tsx, MemoryInspectorPanel.test.tsx: take main (strictly newer, already contains the branch's A2A overlay content plus subsequent a11y/UX fixes) - MemoryInspectorPanel.tsx: take main (543 lines with semantic search) + apply sanitizeId() helper from #904 + update bodyId prefix to mem-body- - DetailsTab.tsx: take main (has #875 Field/useId + #878 deleteButtonRef/focus) + apply alertdialog structure from #905 while preserving focus management Mechanical conflict resolution by triage-agent; no logic changes beyond the four a11y fixes already in the branch (#902-#905).
