- 0001_init.sql: projax.items + projax.item_links tables with indices, partial-unique root slug, updated_at trigger, schema grants to the application role. - 0002_path_trigger.sql: BEFORE-write trigger maintains items.path via recursive parent walk; rejects cycles and structural-rule violations (areas at root, projects not at root). AFTER trigger rewrites descendant paths on slug rename or re-parent. - 0003_seed_areas.sql: dev, sports, home, work, health, finances, social. - db/migrate.go: embed.FS-backed sequential runner. - db/migrate_test.go: integration suite covering idempotency, nest, rename propagation, re-parent propagation, cycle rejection, and structural rules. Skips when no DB env var is set. Also ignores .m/events.log and .m/locks (per-worker scratch).
