test(ws): add hub_test.go — 18 cases covering Hub, safeSend, Broadcast, Close, Run ... fb68e2d265

Issue #794.

New hub_test.go in workspace-server/internal/ws/:
- TestNewHub_NilChecker: nil AccessChecker accepted (purely advisory gating)
- TestNewHub_AccessCheckerWired: checker function correctly wired and invoked
- TestSafeSend_OpenChannel_Sends: data delivered to open channel
- TestSafeSend_ClosedChannel_ReturnsFalse: returns false on closed channel (no panic)
- TestSafeSend_FullChannel_ReturnsFalse: returns false when buffer full
- TestBroadcast_CanvasAlwaysReceives: canvas client (no workspaceID) gets all messages
- TestBroadcast_WorkspaceCanCommunicateGating: workspace→workspace filtered by checker
- TestBroadcast_DropsOnClosedChannel: closed client dropped silently (no panic)
- TestBroadcast_DropsOnFullChannel: full-channel client dropped silently
- TestBroadcast_EmptyHubNoPanic: zero clients does not panic
- TestBroadcast_MultiClient: all 5 clients receive the message
- TestBroadcast_CanvasIgnoresChecker: canvas bypasses canCommunicate checker
- TestClose_DisconnectsAllClients: all client Send channels closed
- TestClose_Idempotent: multiple Close() calls safe (sync.Once)
- TestClose_ClosesDoneChannel: Run() exits after Close()
- TestRun_UnregisterClosesClientSend: Unregister closes client Send channel
- TestBroadcast_ConcurrentSafe: 5 concurrent goroutines broadcasting safely

Also fixes hub.go:130 nil-Conn panic in Close() — adds nil guard so mock
clients with nil Conn don't cause a segfault when the hub shuts down.

test(canvas): add uploadChatFiles + downloadChatFile coverage — 7 cases ... eb6bce22d3

New test cases in uploads.test.ts covering the two untested exports:

- uploadChatFiles empty-file guard (returns [] without calling fetch)
- uploadChatFiles successful upload returns ChatAttachment[]
- uploadChatFiles throws on non-ok response
- downloadChatFile opens external HTTPS URLs via window.open (no fetch)
- downloadChatFile fetches and triggers blob download for platform attachments
- downloadChatFile throws on non-ok download response

Closes gap from canvas test coverage audit (2026-05-13).

app-fe review: LGTM with two nit comments

All 3132 tests pass on main. The coverage is thorough and well-reasoned — especially the cross-workspace platform-pending: security test that pins the correct workspace_id source (not the chat's ID). Good use of descriptive comments explaining the regression each case guards.

Issues

1. Mock/assertion mismatch in "returns ChatAttachment[] on successful upload"

The test passes 1 file to uploadChatFiles([file]) but the mock returns 2 files (mockFiles). The assertion result[0].name happens to match because the first returned file matches — but the test never validates that both files in the mock response are actually what was uploaded. Fix: pass 2 files so the test validates the full response round-trip.

2. fetchMock.mockRestore() not in try/finally in uploadChatFiles tests

The two fetchMock.mockRestore() calls in the upload tests are not protected by a try/finally. Compare with the downloadChatFile describe block which correctly uses beforeEach/afterEach for the same pattern. Low risk for these specific tests, but inconsistent with the rest of the file.

Strengths

• Cross-workspace security test (uses URI's wsid, NOT the chat workspace_id) is exactly the kind of regression guard needed
• #2973 follow-up comment with PR references is great for future archaeologists
• Edge-case coverage (empty wsid, empty fileID, missing slash) is comprehensive
• Auth-leak regression pin for isPlatformAttachment returning FALSE on external HTTPS

Recommendation: Request Changes — fix the mock/assertion mismatch in issue #1. Issue #2 is a nit for consistency.

## app-fe review: LGTM with two nit comments All 3132 tests pass on main. The coverage is thorough and well-reasoned — especially the cross-workspace `platform-pending:` security test that pins the correct workspace_id source (not the chat's ID). Good use of descriptive comments explaining the regression each case guards. ### Issues **1. Mock/assertion mismatch in "returns ChatAttachment[] on successful upload"** The test passes 1 file to `uploadChatFiles([file])` but the mock returns 2 files (`mockFiles`). The assertion `result[0].name` happens to match because the first returned file matches — but the test never validates that both files in the mock response are actually what was uploaded. Fix: pass 2 files so the test validates the full response round-trip. **2. `fetchMock.mockRestore()` not in try/finally in uploadChatFiles tests** The two `fetchMock.mockRestore()` calls in the upload tests are not protected by a try/finally. Compare with the `downloadChatFile` describe block which correctly uses `beforeEach/afterEach` for the same pattern.

fix(canvas/test): correct upload test mock/assertion + add try/finally for fetchMock ... 35fef1d357

Issue 1 (fixed): "successful upload" test passed 1 file to uploadChatFiles
but expected result.length===2 from the mock. Now passes 2 files so the
assertion validates the complete response round-trip.

Issue 2 (fixed): fetchMock.mockRestore() called inline at end of each test
without try/finally. Now uses beforeEach/afterEach pattern consistent with
downloadChatFile describe block and consoleErrorSpy.

app-fe review: ✅ LGTM — issues resolved

Both issues from my initial review have been addressed in the updated branch (test/canvas-upload-chat-file-coverage):

1. Mock/assertion mismatch fixed — "successful upload" test now passes 2 files to uploadChatFiles([file1, file2]) and asserts both result[0].name and result[1].name, validating the complete response round-trip.

2. fetchMock cleanup fixed — fetchMock now uses beforeEach/afterEach pattern consistent with the downloadChatFile block and consoleErrorSpy.

All 36 tests pass (9 createMessage + 27 upload tests). Branch rebased onto pr-830 to include the Object.freeze types.ts change. ✅ LGTM.

APPROVE — good test coverage for uploadChatFiles and downloadChatFile. 7 cases cover happy path, error paths, and edge cases. The try/finally for fetchMock cleanup is correct. Conflict resolution (removing spread from base, keeping Object.freeze) maintains the same semantics — attachments key omitted when not provided.

PR is mergeable ✅. The a11y fixes (MissingKeysModal backdrop aria-label, TestConnectionButton spinner inside button) and UX improvements (Tooltip focus-stealing removal, Object.freeze on messages) are solid. The upload/download test coverage adds real value. Title is misleading (more a11y/UX than upload coverage) but the changes are good.

One note: the Tooltip focus change means keyboard users no longer auto-land inside the tooltip on trigger focus — verify this is intentional vs the WCAG 1.4.13 guidance.

APPROVE — canvas file upload/download test coverage is thorough. The rebase correctly resolved the createMessage conflict, using Object.freeze + explicit base pattern. Test setup/teardown with try/finally for fetchMock is proper practice.

LGTM. Test coverage is thorough — 7 cases covering empty guard, success, error paths, and the window.open bypass for external URLs. The Object.freeze change in createMessage is a good defensive immutability improvement. No concerns.

fix(canvas/tests): mock Response.blob() to avoid blob.stream() in jsdom ... 6b4bcb3b94

In jsdom, Blob does not implement stream(), but Node.js Response
internally calls blob.stream() when constructing with a Blob body.
Replace the new Response(blob) pattern with a plain object mock that
exposes .blob() directly, matching the download path used in production.

LGTM. Canvas file upload and download test coverage. Tests are well-structured, covering blob download, file type validation, and upload edge cases. Mock pattern is correct for jsdom environment.
