- frontmatter `status: done`, `readiness: ready`, `review_pending` (the
nonexistent-path rule settled under autonomy 2026-09-10)
- every criterion met with its evidence: task 1 smokes A–D (`b31bd40`),
residency section 8 checks i–vii (`aaea6b2`), db-bench `--wo-data-file`
181 checks / 5 failures — the same 5 as the directory form
(`residency.keys.fit` rc 74, databasev2 13's sibling, not this defect),
temps-beside-the-log test plus its mutation control (`ccee2d0`)
- the fork, settled: existing dir or trailing `/` → <dir>/shard-0.wal,
byte-identical; otherwise the path IS the log, created behind an existing
parent; a missing parent or a non-regular non-directory path refuses,
exit 2, naming path and parent — never a silent mkdir -p
- `WO_DATA` stays a path: ephemerality is WO_EPHEMERAL=1 (databasev2 2 task
6a), so the file-vs-directory parse carries no `:memory:` sentinel
- progress table with the four hashes; history
