21-04: Same toast ID 'sub-error' across all subscriptions prevents duplicate error notifications

21-04: duration: Infinity keeps toast visible until user dismisses — intentionally sticky

21-04: No reconnection logic added — tRPC SSE httpSubscriptionLink handles reconnection via EventSource retry

21-04: SpawnArchitectDropdown already covered by 21-01 — Task 2 was a verified no-op

Phase 21 Plan 04: Subscription Error Handling Summary

Sticky toast notifications for SSE subscription errors with fixed ID deduplication across all three pages

Performance

Duration: 2 min
Started: 2026-02-05
Completed: 2026-02-05
Tasks: 2 (1 implemented, 1 verified no-op)
Files modified: 3

Accomplishments

Replaced all silent onError: () => {} callbacks with sticky toast notifications on initiatives dashboard, initiative detail, and inbox pages
Used fixed toast ID sub-error so multiple concurrent subscription failures show only one notification
Verified SpawnArchitectDropdown already has full toast coverage from plan 21-01

Task Commits

Each task was committed atomically:

Task 1: Add subscription error handling with toast feedback on all pages - 4ae85da (feat)
Task 2: Verify SpawnArchitectDropdown error toast coverage - no-op (21-01 already applied)

Files Created/Modified

packages/web/src/routes/initiatives/index.tsx - Added toast import, replaced onError with error toast
packages/web/src/routes/initiatives/$id.tsx - Added toast import, replaced both onError callbacks with error toast
packages/web/src/routes/inbox.tsx - Replaced onError with error toast (toast already imported)

Decisions Made

Same toast ID sub-error across all subscriptions prevents duplicate error notifications when multiple subscriptions fail simultaneously
duration: Infinity keeps toast visible until user dismisses it — intentionally sticky so users know live updates are broken
No reconnection logic added — tRPC SSE httpSubscriptionLink already handles reconnection via EventSource retry
SpawnArchitectDropdown was already fully covered by 21-01 (toast.error on onError, toast.success on onSuccess for both mutations)

Deviations from Plan

None - plan executed exactly as written.

Issues Encountered

None

User Setup Required

None - no external service configuration required.

Next Phase Readiness

Ready for 21-05-PLAN.md (Code Splitting & Performance)
All subscription error handling in place
No blockers
