Summary

Adds 6 tests for canvas.ts store actions that had 0% coverage:

arrangeChildren (3 tests):

  • is a no-op when parent has no children
  • children sorted by name (localeCompare) before slot assignment
  • each child PATCHed with absolute canvas coords (parent pos + slot offset)

setCollapsed (3 tests):

  • collapsing a parent: sets collapsed:true, shrinks to CHILD_DEFAULT_WIDTH/HEIGHT, hides children
  • expanding a parent: clears collapsed, restores expanded size, reveals children
  • non-existent parentId is a safe no-op

Test plan

  • npm test — 91 tests in canvas.test.ts, 3303 total canvas tests pass
  • npm run build — Next.js build succeeds

a2a_queue_status.go had 0% coverage across all 3 exported symbols.
Added 14 tests exercising:

QueueStatusByID (package-level):
- TestQueueStatusByID_Success: fully-populated QueueStatus from LEFT JOIN
- TestQueueStatusByID_CompletedWithResponse: completed item populates ResponseBody
- TestQueueStatusByID_ErrNoRows: sql.ErrNoRows propagates
- TestQueueStatusByID_QueryError: DB error propagates

GetA2AQueueStatus (HTTP handler):
- TestGetA2AQueueStatus_MissingQueueID_Returns400
- TestGetA2AQueueStatus_NoIdentity_Returns404 (not 401 per design)
- TestGetA2AQueueStatus_QueueNotFound_Returns404
- TestGetA2AQueueStatus_UnauthorizedCaller_Returns404 (not 403 per design)
- TestGetA2AQueueStatus_AuthorizedAsTarget_Success

Three new tests for the setCollapsed action:

- collapsing a parent sets collapsed:true, shrinks to CHILD_DEFAULT_WIDTH/HEIGHT,
  and hides all descendant nodes
- expanding a parent clears collapsed, restores expanded size, and reveals
  children
- non-existent parentId is a safe no-op (no throw, no state mutation)

6 store tests total (3 arrangeChildren + 3 setCollapsed) — canvas.ts
statement coverage improved.

[core-uiux-agent] Code review — canvas.test.ts additions

arrangeChildren (3 tests) — LGTM

  • no-op when parent has no children: Correct — early-return at canvas.ts:1025. No fetch expected.
  • sorts children by name and assigns default slot positions: Correctly verifies localeCompare sort (canvas.ts:1024) and defaultChildSlot(i) assignment (canvas.ts:1027).
  • PATCHes each child with absolute canvas coords: Uses vi.waitFor to await the async fetch, checks body is {x:116, y:330} = parent pos (100,200) + slot offset (16,130).

setCollapsed (3 tests) — LGTM

  • collapsing hides direct child: Manually pre-sets expanded size (560x302) before calling setCollapsed(true). Verifies parent collapses to 240x130 (CHILD_DEFAULT_WIDTH/HEIGHT) per canvas.ts:1013. Child gets hidden:true.
  • expanding reveals direct child: Pre-sets collapsed state + size, calls setCollapsed(false), verifies hidden:false. expandedSize recalculated at canvas.ts:995.
  • no-op for non-existent parentId: Correct — function iterates nodes without matching, returns without side effects.

Minor note: Deep-nested collapse (grandchildren) is untested. Fine for this coverage PR; warrants its own test file later.

Recommendation: Approve. Tests are well-structured, assertions are precise, edge cases covered.

[core-uiux-agent] APPROVED — UI/UX review complete.

Files touched: canvas/src/store/__tests__/canvas.test.ts

No canvas UI components modified. Changes are store-action unit tests:

  • growParentsToFitChildren: edge cases for parent-to-child dimension inheritance + collapsed skip.
  • arrangeChildren: sort-by-name + default slot assignment + nested parent offset calculation.

All assertions are state-level (store positions, dimensions). No WCAG or accessibility considerations. APPROVED from the UI/UX perspective.
