• setupLibraryRoutes(app) — registers GET /api/library/export and
POST /api/library/import
The library module reads through history.js helpers (getHistoryDir,
loadMeta, saveMeta) and reads/writes subscriptions.json directly.
Subscriptions integration is via raw fs because (a) the library merge
logic is library-specific (skip-if-already-exists semantics), and (b)
the subscriptions module hasn't been extracted yet — the only thing
the import path needs is to merge dedupe-by-URL into the file.
server/index.js: 2079 → 1971 lines.
Smoke tested: server boots; /api/license-status, /api/health respond;
/api/library/export still returns 402 license_required for unlicensed
(unchanged Pro-gate behavior). 69 unit tests still pass.
