Browse source 
- Task 6 note: db fixtures live in existing corpus kinds; crash battery
  proven at unit level; select fixtures wait on 9b's read surface

### Task 6: DB corpus + acceptance
### Task 6 🔄: DB corpus + acceptance — **landing incrementally**

**Concept & reason:** the corpus grows a `db/` kind wired into the standard runner: insert/select round-trip programs with exact stdout; the crash/replay battery as a scripted scenario (run, kill, reboot, assert identical query results); a unique-violation trap fixture; the C++ `wo-db` smoke overlap — where `prototypes/wo-db`'s `.wo` smoke files exercise semantics this subset implements, run both and compare (manifest-scoped like the plan-3 parity harness). `just oop-accept` gains the DB corpus and the crash scenario. The kanban and CLAUDE.md sync: Stage-3-adjacent language ("insert/select execute in the C runtime") replaces the DB_STUB story.
