# Phase 06.3 Plan 14: D-57 tweenTo Fix Summary

**The reconciler adapter now uses a real Phaser tween instead of hard-snapping with `setPosition()`.**

## Accomplishments

- Replaced the `tweenTo(..., _ms) => local.setPosition(...)` stub with `this.tweens.killTweensOf(local)` plus `this.tweens.add(...)`.
- Preserved the existing adapter interface and duration passed by `ReconcileEngine`.

## Task Commits

1. **Task 1/2: Phaser tween adapter** - `b91f6d5` (`fix(06.3-14)`)

## Verification

- `pnpm --filter @rebno/client test --run` - PASS, 26 test files passed, 191 tests passed, 4 todo.
- `pnpm --filter @rebno/client typecheck` - PASS.

## Next Phase Readiness

Ready for D-58 idle convergence assessment. Staging UAT should confirm `lastReconcileReason` no longer repeatedly hits `divergence-threshold` during normal movement.
