# Phase 06.3 Plan 15: D-58 Idle Convergence Summary

**No separate idle guard was added: the reconciler has no idle skip, and D-58 is expected to converge through the D-57 tween fix.**

## Accomplishments

- Added an in-code note documenting that idle snapshots use the same reconciliation path as motion snapshots.
- Confirmed the D-57 `tweenTo` fix makes the existing lerp path operational.

## Task Commits

1. **Task 1/2: D-58 convergence note** - `c8119c9` (`fix(06.3-15)`)

## Verification

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

## Not Run

- Staging idle convergence UAT was not run in this local pass. Wave-2 staging verification must confirm `window.__rebno.lastReconcileDist <= 3` after idle.
