+# Phase 3 Plan 1 Summary
+
+**Node-safe four-layer state construction with injected legacy boundaries and an awaited replay movement/event/map tracer**
+
+## Performance
+
+- **Duration:** 19 min
+- **Started:** 2026-09-10T15:27:00+08:00
+- **Completed:** 2026-09-10T15:46:21+08:00
+- **Tasks:** 2
+- **Files modified:** 13 implementation/test files, plus planning ledgers
+
+## Accomplishments
+
+- Guarded logger and game-loading module evaluation against missing `main`, `window`, `document`, and `location` globals
+- Added `MemorySaveSystem`, parameterless `createCoreState()`, independent Node-safe construction, and centralized legacy dependency injection
+- Removed the enemy calculator singleton edge and legacy movement barrel edge without reintroducing a data-state singleton into the Node path
+- Added a fixed three-cell map tracer that awaits hero movement and source-aware enter-event mutation before replay completion
+- Removed two Node blockers: nonstandard `Map.getOrInsertComputed` use in the event path and the replay sandbox play-loop state guard
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: singleton back-edge 修复与 Node-safe CoreState construction tracer** - `a707be4` (feat)
+2. **Task 2: Node-safe CoreState 与最小 replay→move→event→map tracer** - `4eec086` (feat)
+
+**Plan metadata:** pending final metadata commit
+
+## Files Created/Modified
+
+- `packages-user/data-common/src/save/memory.ts` - in-memory save/global storage adapter that does not instantiate Dexie
+- `packages-user/data-state/src/legacy/dependencies.ts` - internal host-aware legacy converter and loading boundary
+- `packages-user/data-state/src/core.ts` - no-options factory and dependency-driven four-layer constructor
+- `packages-user/data-state/test/fixtures/closed-loop.ts` - fixed map, event, and direct replay fixture
+- `packages-user/data-state/test/nodeTracer.test.ts` - focused Node construction and replay closure tests with Chinese `it` comments
+- `packages/common/src/logger.ts`, `packages-user/data-base/src/game.ts` - Node-safe global guards
+- `packages-user/data-base/src/map/mapLayer.ts`, `packages-user/data-common/src/replay/sandbox.ts` - runtime fixes required by the tracer
+
+## Decisions Made
+
+- Kept the public factory contract parameterless; host selection and legacy injection remain internal to the constructor boundary
+- Kept the compatibility singleton available through the existing barrel while direct Node tests import `src/core.ts`
+- Used the existing `DefaultHeroMoveTopImpl`, `EventExecutor`, and `ReplaySandbox` instead of creating a parallel movement or event engine
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 1 - Bug] Avoided reading an uninitialized hero mover during construction**
+- **Found during:** Task 1
+- **Issue:** `HeroLocation` constructs `HeroMover` before assigning `location.mover`, while the mover constructor read `tile.getCurrentFaceDirection()` and crashed in Node
+- **Fix:** Initialize the base mover with `FaceDirection.Unknown`; the location constructor applies the requested initial direction immediately afterward
+- **Files modified:** `packages-user/data-base/src/hero/mover.ts`
+- **Verification:** Node factory probe and focused tracer pass
+- **Committed in:** `a707be4`
+
+**2. [Rule 3 - Blocking] Removed the event-layer dependency on a nonstandard Map prototype extension**
+- **Found during:** Task 2 tracer execution
+- **Issue:** The real movement path called `Map.getOrInsertComputed`, which is absent in a clean Node process and stalled the movement Promise
+- **Fix:** Replaced it with explicit `Map.get`/`Map.set` construction
+- **Files modified:** `packages-user/data-base/src/map/mapLayer.ts`
+- **Verification:** Focused tracer and full four-package data suite pass without a global Map shim
+- **Committed in:** `4eec086`
+
+**3. [Rule 1 - Bug] Allowed ReplaySandbox.play() to execute its command loop**
+- **Found during:** Task 2 tracer execution
+- **Issue:** `ReplaySandbox.play()` sets `pausing` false, but `step()` rejected every step while not paused, so replay never reached `ended`
+- **Fix:** `step()` now rejects only inactive or already-ended sandboxes, preserving paused single-step behavior while allowing the play loop
+- **Files modified:** `packages-user/data-common/src/replay/sandbox.ts`
+- **Verification:** Replay tracer reaches normal end after the awaited movement/event Promise; full data suite passes
+- **Committed in:** `4eec086`
+
+---
+
+**Total deviations:** 3 auto-fixed (1 Rule 1 bug, 1 Rule 3 blocking issue, 1 Rule 1 replay bug)
+**Impact on plan:** All fixes were direct blockers for the requested Node/replay vertical tracer; no new public interface or package dependency was introduced.
+
+## Known Stubs
+
+- `packages-user/data-common/src/save/memory.ts:90` — `saveAutosaveToDB()` is intentionally a no-op in the Node adapter because the Node path must not persist to IndexedDB; recorded in `.planning/WINDOWS.md`.
+- `packages-user/data-state/src/legacy/dependencies.ts:51` — the Node boundary intentionally registers no browser loading callback; recorded in `.planning/WINDOWS.md`.
+- `packages-user/data-state/src/core.ts:156` — serialized external event registration remains the existing deferred TODO for later Phase 3 assembly; recorded in `.planning/WINDOWS.md`.
+
+## Issues Encountered
+
+- `pnpm check:type` remains non-zero on pre-existing render/legacy diagnostics and the user-owned Tile events contract mismatch (`TileStore`/`TileLegacyBridge` still use the old `trigger` shape). No new diagnostics were reported in the new fixture/test files or the memory/dependency boundary files. The issue is logged in `deferred-items.md` and `.planning/WINDOWS.md` for the later tile-events/type closure plan.
+
+## Verification
+
+- PASS: `pnpm exec vitest run packages-user/data-state/test/nodeTracer.test.ts` — 2 tests
+- PASS: `pnpm test:ci packages-user/data-common packages-user/data-base packages-user/data-system packages-user/data-state` — 11 files, 60 tests
+- PASS: exact canonical madge back-edge check for `enemy/calculator.ts -> ins.ts` and `legacy/move.ts -> index.ts`
+- PASS: direct Node factory probe creates two distinct `MemorySaveSystem`-backed states
+- DEFERRED: repository-wide `pnpm check:type`, due only to pre-existing render/legacy and Tile contract diagnostics
+
+## User Setup Required
+
+None - no external service configuration required.
+
+## Next Phase Readiness
+
+- The next replay/event plans can consume a direct Node-safe `CoreState` and fixed fixture without browser globals or IndexedDB.
+- Top-level replay enum/registration and event built-ins remain intentionally delegated to the subsequent Phase 3 plans.
+- The repository-wide type gate remains deferred as documented; the focused Node tracer and all current data-package tests are green.

+# Deferred Items — Phase 03
+
+- `pnpm check:type` remains blocked by pre-existing render/legacy diagnostics and the user-owned Tile events contract migration (`TileStore.getEvent` and `TileLegacyBridge` still use the old `trigger` shape). The migration is outside Plan 03-01 and remains assigned to the later Phase 3 tile-events plan.
