Phase 1 Plan 3: Async Draft Safety Summary

Field-scoped async guards, invalid draft preservation, and save-failure recovery for runtime settings

Performance

• Duration: 18 min
• Started: 2026-03-29T02:53:00Z
• Completed: 2026-03-29T03:10:41Z
• Tasks: 2
• Files modified: 5

Accomplishments

• Added helper logic in runtime-settings-form.ts to distinguish valid selection preservation from invalid drafted model paths
• Hardened RuntimeSettingsDrawer.tsx so async scans and pickers update only their owned fields, ignore stale results, and keep invalid draft values visible inline
• Added regression coverage for stale async protection, invalid draft save blocking, and failed-save draft preservation

Task Commits

Each task was committed atomically:

1. Task 1: Make async picker and rescan handlers field-scoped and stale-safe - 80883c2 (feat)
2. Task 2: Preserve invalid drafts visibly and block save until resolved - 80883c2 (feat)

Plan metadata: pending

Files Created/Modified

• tauri-app/src/features/runtime/components/RuntimeSettingsDrawer.tsx - Shared async request guarding, inline invalid-state messaging, and save blocking for pending or invalid draft fields
• tauri-app/src/features/runtime/runtime-settings-form.ts - Draft model resolution helper that keeps missing selections visible and marked invalid
• tauri-app/src/features/runtime/runtime-settings-form.test.ts - Unit coverage for preserved selections and invalid draft outcomes
• tauri-app/src/features/runtime/components/RuntimeSurface.test.tsx - Runtime regression tests for stale async responses, invalid draft preservation, and failed-save recovery
• tauri-app/src/features/runtime/useRuntimeManager.ts - Draft metadata update helpers used by the controlled drawer for pending and invalid field state

Decisions Made

• Unified scan, folder browse, and file-pick draft updates under one model-selection request channel so later user intent always wins over earlier async work
• Disabled Save changes whenever invalid or pending draft metadata exists to match the locked Phase 1 trust contract

Deviations from Plan

Auto-fixed Issues

1. [Integration] Extended manager metadata APIs for pending and invalid field state

• Found during: Task 2 (invalid draft preservation)
• Issue: The typed manager contract existed, but the drawer needed a write path for field-level pending and invalid metadata
• Fix: Added updateDraft and updateDraftFieldMeta support in tauri-app/src/features/runtime/useRuntimeManager.ts
• Files modified: tauri-app/src/features/runtime/useRuntimeManager.ts
• Verification: npm test -- RuntimeSurface; npm test -- runtime-settings-form; npm run build
• Committed in: 80883c2

---

Total deviations: 1 auto-fixed (integration) Impact on plan: Required to complete the planned invalid-state behavior. No user-facing scope expansion beyond Phase 1 draft safety.

Issues Encountered

• The stale-response test originally used two rescan requests, but the UI correctly disables a second rescan while one is already in flight; the regression was adjusted to cover a pending initial scan followed by a later folder browse request against the same model-selection guard

User Setup Required

None - no external service configuration required.

Next Phase Readiness

• Phase 1 draft safety is complete: polling, discard, invalid values, async rescans, and save failures now preserve user intent
• Phase 2 can build explicit lifecycle command semantics on top of a trusted settings surface instead of compensating for draft-state bugs

Self-Check

PASSED

• Verified helper-level selection and invalid-draft behavior with npm test -- runtime-settings-form
• Verified stale async guards, invalid draft blocking, and save-failure recovery with npm test -- RuntimeSurface
• Verified production compile with npm run build
