The classifier re-scanned the source on every session; on cloud-backed mounts
(OneDrive/Samba) that's minutes of per-op latency. Workspaces fix it: scan a
folder ONCE, snapshot the completed tree, and resume instantly — all
classification runs on the data model; the filesystem is only touched at copy.
- persist.js v2: multi-workspace IndexedDB (tiny 'index' store for the welcome
list + 'data' store holding the source handle, tree snapshot, and map). DB v2.
- scanner.js: snapshotTree()/loadSnapshot() (compact, handle-less, marked done,
totals recomputed) + lazy resolveFileHandle/resolveDirHandle from the root.
- workspace.js: welcome manager (new/open/rename/delete), debounced autosave of
the active workspace, 'Refresh from disk' (re-scan → re-snapshot, path-keyed
map carries over). New workspace = the one slow full scan; reopen = instant.
- copy.js: resolves snapshot files' handles from the workspace root with a
one-click read permission re-grant; missing-on-disk files surface as errors.
- app.js: enterAppShell() shared by rename/workspace flows; exposes setMode;
classify.js decoupled from persistence.
- template/css: welcome workspace list + header 'Workspaces' button.
- tests: snapshot round-trip, persist CRUD + classify-only-preserves-tree,
copy-from-snapshot via mock root handle (28 classify/classifier tests green).

- Each source file row shows a classification state dot (unassigned →
has-tracking/transmittal → done), and each folder shows an aggregate dot
over its subtree.
- Right-click a file or folder to Exclude/Include from the copy (folder applies
to its whole subtree) or clear an axis; excluded files are struck through and
never copied.
- Cross-tree find is bidirectional: click a placed file in the target pane to
reveal+flash it in the source tree (expanding its folders); click a source
file to switch the target pane to its placed axis and flash the node.
- Target pane now reverse-looks-up over ALL scanned files (the left tree), not
the selection-scoped grid, with placements grouped in one pass per render.
- classify.getAssignment() read-only accessor; 5 new tests (18 total green).

Foundation for the non-destructive map+copy workflow: source stays read-only,
files are mapped onto two orthogonal target trees, a later step copies renamed
copies to a separate output dir.
- classify.js: the single source of truth. assignments map keyed by
source-relative path (survives re-pick); tracking tree (positional: ancestors
joined '-' = tracking number, immediate parent 'REV (STATUS)' leaf = rev+status,
title from original name) and transmittal tree (<party>/{received,issued}/<bin>).
deriveTarget() computes filename + output path + validation purely; pub/sub +
debounced autosave; node CRUD with dangling-placement cleanup.
- persist.js: IndexedDB store of the serialized map + the source
FileSystemDirectoryHandle, with queryPermission/requestPermission re-grant on
reload and a re-pick fallback.
- tests/classify.spec.js: 9 in-page unit tests for the derive/assignment logic
(no FS Access needed) — tracking join, leaf REV (STATUS) parse incl. invalid
status, title derivation/override, transmittal path composition, exclude,
cascade delete.
