- Replaced approved-plan renaming with `resolveApprovedPlan` resolution and state/slug lookup.
- Updated ACP and interactive apply flows to propagate canonical `planFilePath` instead of renamed paths.
- Added local plan fallback lookup by mtime for unresolved slugs after plan approval.
- Restricted plan-mode writes to `local://` plan artifacts and simplified path handling.
- Added shared `getReadToolPath` API to extract paired read `path` values for protection matchers.
- Added `createPlanReadMatcher` and session wiring so compaction prune/shake keeps active plan reads intact.
- Updated `todo-write` instructions to initialize every user-supplied plan item as an individual task.
- Added compaction tests validating plan reads are protected from prune and shake while regular reads are still removable.
