sneak	76141ae919	feat(library/store): on-disk JSON metadata store for the local cache ... Add `MetadataStore` (src/library/store.ts): one metadata.json holding the user id, schema version, collections cursor, and decrypted collection and file records. Loaded whole into RAM with Maps for id lookups; rewritten whole through the download layer's fsync atomic writer (temp, fsync, rename, dir fsync). Binary keys are base64-encoded on disk. A missing, unparseable, or wrong-schema file loads as an empty store, because the file is only a cache the refresh unit repopulates. Directory 0700, file 0600, matching session.json. No lock file; no sync() beyond the writer. This unit only stores; issue 42's refresh unit populates it. (closes #41) Model: opus-4-8	2026-09-22 10:46:17 +00:00
sneak	15ceac857a	test(library/store): metadata store round-trip, empty-on-corrupt, perms ... Failing first: the on-disk JSON metadata store does not exist yet. These tests fix its contract before the implementation lands — round-trip fidelity including the binary keys, missing/corrupt files loading empty, a schema-version mismatch discarded as stale cache, atomic writes leaving no temp sibling, and directory 0700 / file 0600 permissions.
