requires: []
provides:
- runtime draft ownership contracts for live, baseline, and editable runtime state
- manager-owned polling reconciliation that preserves dirty drafts
- regression coverage for poll-safe draft edits, close or reopen preservation, and save promotion

key-decisions:
- "Keep existing snapshot/saveConfig outputs while adding explicit draft APIs so brownfield consumers keep compiling during the Phase 1 transition."
- "When the draft is dirty, polling updates only operational live fields and leaves baseline plus draft config untouched."
patterns-established:
- "Runtime manager owns liveSnapshot, savedBaseline, and draftConfig separately instead of deriving editable state from polling output."
- "Draft behavior is verified with hook-level regression tests that exercise open, close, update, poll, and save flows independently from the drawer UI."

# Phase 1 Plan 1: Draft State Ownership Summary
**Manager-owned runtime draft contracts with polling-safe reconciliation and save-promotion regressions for the Tauri runtime workspace**
## Performance
- **Duration:** 10 min
- **Started:** 2026-03-29T02:43:00Z
- **Completed:** 2026-03-29T02:52:44Z
- **Tasks:** 2
- **Files modified:** 4
## Accomplishments
- Added explicit draft-state contracts for live snapshot, saved baseline, editable draft config, and field metadata in `tauri-app/src/features/runtime/types.ts`
- Refactored `useRuntimeManager` to own `liveSnapshot`, `savedBaseline`, and `draftConfig` separately while preserving legacy `snapshot` and `saveConfig` compatibility
- Added regression coverage proving dirty drafts survive polling, hidden drafts survive close or reopen in-session, and save promotes the returned config into the new clean baseline
## Task Commits
Each task was committed atomically:
1. **Task 1: Define runtime draft ownership contracts** - `929a516` (feat)
2. **Task 2: Move draft, baseline, and polling reconciliation into the runtime manager** - `18501e9` (feat)
**Plan metadata:** pending
## Files Created/Modified
- `tauri-app/src/features/runtime/types.ts` - Defines reusable draft-state contracts and default field metadata for manager-owned runtime editing
- `tauri-app/src/features/runtime/runtime-settings-form.test.ts` - Verifies the new draft contract surface with runtime-backed and type-level assertions
- `tauri-app/src/features/runtime/useRuntimeManager.ts` - Separates live polling state from saved baseline and editable draft state while keeping legacy consumers working
- `tauri-app/src/features/runtime/components/RuntimeSurface.test.tsx` - Covers dirty polling reconciliation, close or reopen draft persistence, and save promotion behavior through the runtime manager harness
## Decisions Made
- Kept `snapshot` and `saveConfig` on the manager return value so the current drawer keeps working while Phase 1 transitions draft ownership into the manager
- Treated dirty polling as an operational refresh only, updating status and process health without replacing draft or baseline config values
## Deviations from Plan
None - plan executed exactly as written.
## Issues Encountered
- The first RED attempt used type-only assertions, which Vitest transpiled without failing on missing exports; the contract test was adjusted to use runtime-backed draft helpers so the TDD red phase became real before implementation
## User Setup Required
None - no external service configuration required.
## Next Phase Readiness
- Phase 1 now has a typed draft-state foundation and manager behaviors the drawer refactor can consume directly
- The next plan can move the drawer UI onto the manager-owned draft API without re-solving polling or save-baseline ownership rules
