Phase 2 Plan 02: Lifecycle Command Safety Summary

Frontend runtime state now tracks explicit lifecycle commands, completion messages, and restart/apply impact on top of the Phase 1 draft model

Performance

• Duration: 14 min
• Started: 2026-03-29T03:56:04Z
• Completed: 2026-03-29T04:10:22Z
• Tasks: 2
• Files modified: 5

Accomplishments

• Added frontend lifecycle command, result, and apply-impact types plus fallback snapshot support in the runtime API layer.
• Refactored the runtime manager to expose activeLifecycleCommand, lastLifecycleResult, lifecycleBusy, and applyImpact while keeping dirty-draft polling safety intact.
• Expanded RuntimeSurface tests to cover lifecycle metadata mirroring, apply-impact classification, start/stop progress, and restart-required manager state.

Task Commits

Each task was committed atomically:

1. Task 1: Mirror backend lifecycle metadata and define frontend apply-impact contracts - a72c902 (test)
2. Task 1: Mirror backend lifecycle metadata and define frontend apply-impact contracts - 2cb6cad (feat)
3. Task 2: Replace generic busy handling with action-specific manager state - 1d45342 (test)
4. Task 2: Replace generic busy handling with action-specific manager state - 1bcd4be (feat)

Files Created/Modified

• tauri-app/src/features/runtime/types.ts - mirrors backend lifecycle fields and apply-impact unions in the frontend contract.
• tauri-app/src/features/runtime/api.ts - preserves lifecycle result metadata in local fallback snapshots.
• tauri-app/src/features/runtime/runtime-utils.ts - classifies apply impact from the backend restart-required field list and provides lifecycle result defaults.
• tauri-app/src/features/runtime/useRuntimeManager.ts - owns explicit lifecycle progress and completion state alongside the existing draft/live split.
• tauri-app/src/features/runtime/components/RuntimeSurface.test.tsx - covers manager lifecycle semantics through the React runtime feature harness.

Decisions Made

• Normalized snapshots inside the manager so older fallback payloads and fresh backend payloads both produce defined lifecycle fields.
• Kept busy available for brownfield consumers while adding explicit lifecycle state that plan 02-03 can render directly.
• Used the backend restart-required field list (connection_mode, model_path, addr, gpu_layers, ctx_size) as the only source of truth for restart_required apply impact.

Deviations from Plan

None - plan executed as written.

Issues Encountered

• None.

User Setup Required

None - no external service configuration required.

Next Phase Readiness

• RuntimeStatusCard and RuntimeSettingsDrawer can now render explicit lifecycle progress and apply guidance from manager props instead of inferring from busy.
• Phase 2 UI work can show restart-required and save-before-apply messaging without re-implementing backend guard logic.
