## Implementation status (as of review)

- **Implemented:** All commands in §02 (connection, strings, TTL, hashes, sets, SCAN, admin), plus Lists (§07), Sorted Sets (§08), FT.* (§09), BLPOP/BRPOP (§10). Migration API with bulk, dirty tracker, apply-dirty, migrateSearch (§11).
- **Schema:** Matches §03 and extends to list/zset/search tables per §07, §08, §09.
- **Specs:** SPEC_A–F have been split into the files above; content is unchanged except in Appendix F: the duplicate “F.10 Search Index Migration” was renumbered to **F.12**, and “F.12 Operational Guidance” to **F.13**.
