-- D1 schema for the jobsdb snapshot (documents/postings/jobs.db). Applied first by
-- scripts/import-postings.ts as .import/0000-schema.sql; idempotent.
--
-- `postings` mirrors the source table column-for-column (all TEXT). `companies`
-- carries only what src/portals/jobsdb.ts reads. `postings_fts` is a
-- self-contained FTS5 table (not external-content: those need the shadow
-- tables, which `wrangler d1 execute --file` cannot bulk-load sanely), joined
-- on posting_id rather than rowid.
