# Starting point: FE engineer, OPFS after IndexedDB + Cache API

Learner is a frontend engineer with completed SSE, Web Workers, IndexedDB, and Cache API missions in this repo. Goal (issue #4) is practical judgment for file-shaped client storage via the Origin Private File System — not shipping one SQLite-wasm demo. OPFS was already the “file-shaped / origin-private FS” contrast on the IndexedDB and Cache API storage spectra; do not re-teach that spectrum from zero. First ZPD lesson: place OPFS firmly as origin-private file/directory storage (not user-visible pickers, not keyed entity DB, not Cache Storage), and practice choose/reject decisions.
