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.
