Windows runs treated `/tmp/elsewhere/x.md` as relative because Windows
absolute paths require a drive letter, so `_classify_drawer` routed
`drawer_out_of_scope` to `no_source` instead of `out_of_scope` and
`test_dry_run_classifies_correctly` failed on test-windows.
`Path(tmp_dir) / "elsewhere" / "x.md"` is absolute on every platform
and still lives outside the project root that the synced_world fixture
exposes via `repo_path`, so the bucket assertions hold cross-platform.
CI fix: `_classify_drawer` now resolves `source_file` symmetric to
`project_roots` (which `_normalize_project_dirs` and
`_auto_detect_project_roots` already `.resolve()`). Without this, on
platforms where the temp directory is a symlink (macOS `/var/folders` ->
`/private/var/folders`, Windows 8.3 short-name normalization), every
drawer mis-bucketed as `out_of_scope` and survived prune.
Perf:
- `_resolve_project_root`: early-return on first match (sorted-desc
precondition).
- `_normalize_project_dirs`: sort `(-len(str(p)), str(p))` desc for
early-return + deterministic tie-break on equal-length paths.
- `_auto_detect_project_roots`: `seen_sources` dedupe so a 200-chunk
file costs one disk walk, not 200.
- `sync_palace` main loop: per-file classification cache; registry
sentinels (`_reg_*`, `room=_registry`, `ingest_mode=registry`) routed
to "kept" before cache lookup so a sentinel sharing a `source_file`
with a pruned drawer cannot inherit a stale "gitignored" verdict.
- Closet purge: collapse O(N) per-file purge into one
`where={"source_file": {"$in": [...]}}` get + one bulk delete.
Tests (5 new in `TestSyncPalace`, 38 total):
- `test_symlinked_project_root_resolves`: pins symmetric resolve via
real `os.symlink` (skipped on Windows).
- `test_classification_cache_avoids_redundant_disk_hits`: monkeypatch
counter on `_classify_drawer` asserts `call_count == 1` for 5 chunks
sharing one source_file.
- `test_closet_batch_purge_single_call`: wraps closets collection with
`CallCountingCol` (forwards `.get`/`.delete`); asserts
`delete_calls == 1` and `get_calls == 1`; expected `removed_closets`
derived from `report["by_source"]` to stay robust to fixture changes.
- `test_registry_check_runs_before_cache_lookup`: a regular drawer
caches "gitignored" first; a sentinel with the same source_file must
still be kept.
- `test_normalize_project_dirs_sort_stable_on_equal_length`: pins the
alphabetical secondary key when paths share length.
Add `mempalace sync` CLI command and `mempalace_sync` MCP tool that
prune drawers whose source files are gitignored, deleted, or moved
out of the project. Reuses the existing GitignoreMatcher
infrastructure in mempalace/miner.py so the same gitignore rules
that block ingest also drive the corresponding cleanup.
Closes#1252.
