// Rebuilds tests/fixtures/legacy/legacy-v244.sql: a database as the v4.3.3 release left it.
//
// 1. `git archive v4.3.3` the server sources into a temp dir outside the repo and
//    point its node_modules at this checkout's (the runner only needs better-sqlite3,
//    bcryptjs and @trek/shared, none of which changed shape for it).
// 2. Boot that release's own database layer once against an empty file, so the
//    schema is exactly what its createTables() and positional runner produced.
// 3. Insert synthetic rows across the main tables, pin every timestamp, VACUUM.
// 4. Write the result as a sqlite3 `.dump`-style script, then delete the temp dir.
//
// Run from server/: node scripts/build-legacy-fixture-v244.mjs
