provides:
  - controlled runtime settings drawer wired to manager-owned draft state
  - explicit draft-vs-live presentation with sticky Draft settings header and Live now references
  - inline discard confirmation flow that preserves draft state on close and reverts only on explicit confirmation

key-decisions:
  - "Wire drawer visibility through manager open or close actions so backdrop and close hide the in-session draft instead of discarding it."
  - "Use inline draft badges plus Live now helper rows so changed values are distinguishable without relying on color alone."
patterns-established:
  - "Runtime settings UI reads draftConfig and savedBaseline directly rather than mirroring snapshot.config into local form state."
  - "Discard changes opens a confirmation row; only Revert to saved performs the reset."

# Phase 1 Plan 2: Draft Presentation Summary

**Controlled runtime drawer with explicit draft or live presentation, sticky draft copy, and confirmed discard semantics**

## Performance

- **Duration:** 18 min
- **Started:** 2026-03-29T02:53:00Z
- **Completed:** 2026-03-29T03:10:41Z
- **Tasks:** 2
- **Files modified:** 4

## Accomplishments
- Refactored `RuntimeSettingsDrawer.tsx` into a controlled draft editor that reads manager-owned draft and baseline values
- Added sticky `Draft settings` and `Live now` presentation, draft badges, and explicit `Save changes` and `Discard changes` copy
- Added drawer-level regression coverage for visible draft state, close or reopen preservation, and explicit discard confirmation behavior

## Task Commits

Each task was committed atomically:

1. **Task 1: Convert the drawer to a controlled draft/live presentation** - `80883c2` (feat)
2. **Task 2: Add drawer-level tests for draft visibility and explicit discard semantics** - `80883c2` (feat)

**Plan metadata:** pending

## Files Created/Modified
- `tauri-app/src/features/runtime/components/RuntimeSettingsDrawer.tsx` - Controlled draft editor with sticky header, live reference rows, and discard confirmation flow
- `tauri-app/src/features/runtime/components/RuntimeSettingsDrawer.css` - Draft-state, live-reference, sticky header and footer, and discard confirmation styling
- `tauri-app/src/features/runtime/components/RuntimeSurface.test.tsx` - Drawer-level regression tests for draft copy, close or reopen preservation, and discard confirmation
- `tauri-app/src/components/Sidebar.tsx` - App-shell wiring so opening and closing the drawer goes through manager draft actions

## Decisions Made
- Routed drawer open and close through the manager API so hidden drafts survive close and reopen within the same session
- Kept the local runtime apply CTA separate from `Save changes` while still putting draft save and discard semantics in the primary footer flow

## Deviations from Plan

### Auto-fixed Issues

**1. [Integration] Added sidebar wiring for controlled draft opening and closing**
- **Found during:** Task 1 (controlled drawer refactor)
- **Issue:** The plan focused on drawer files, but the app shell still opened the drawer through local UI state only
- **Fix:** Updated `tauri-app/src/components/Sidebar.tsx` to call `openDraft`, `closeDraft`, `resetDraft`, and draft update handlers from `useRuntimeManager`
- **Files modified:** `tauri-app/src/components/Sidebar.tsx`
- **Verification:** `npm test -- RuntimeSurface`; `npm run build`
- **Committed in:** `80883c2`

---

**Total deviations:** 1 auto-fixed (integration)
**Impact on plan:** Necessary brownfield wiring only; no scope creep beyond enabling the planned controlled drawer behavior.

## Issues Encountered
- None

## User Setup Required

None - no external service configuration required.

## Next Phase Readiness
- The drawer now exposes explicit draft and live semantics, which gave Plan 03 a stable surface for async safety and invalid-draft handling
- Controlled draft UI is in place for future lifecycle-semantics work in Phase 2

## Self-Check

PASSED

- Verified explicit draft and live copy in `tauri-app/src/features/runtime/components/RuntimeSurface.test.tsx`
- Verified discard confirmation and close or reopen draft preservation with `npm test -- RuntimeSurface`
- Verified production compile with `npm run build`
