MatriQs — WASM SQLite deployment spike

Read-only proof of concept. Proves in-memory WASM SQLite loads from a plain static host and round-trips to a user-owned file. Nothing here is part of the MatriQs app.

Offline proof: this page fetches nothing from the internet — the SQLite engine (vendor/sqlite3.mjs + vendor/sqlite3.wasm) is served from this folder only. To prove it runs offline, disconnect the network and reload the page: if the checks below still pass, it is genuinely self-contained. (It must be served over http://, not opened as a file:// path.)

Acceptance checks — read these four lines

PENDING 1. Engine loaded Loading the WASM SQLite engine…
PENDING 2. In-memory DB Waiting for the engine.
PENDING 3. Save to file Click “Save database to file” below.
PENDING 4. Reopen & verify Pick the file you saved, then click “Reopen & verify”.

Environment

Diagnostics (not part of the four acceptance checks)

PENDING Self-test round-trip Optional: exports and re-imports entirely in memory, no file dialog. Isolates the engine from the file layer.
