All 19 tasks were already [x] with no prior validate_impl record.
Full suite 9/9 green, 46/46 requirement acceptance criteria mapped,
fresh 6-round live chaotic-multi-kill soak PASS (zero committed
divergence/job loss), src/lib/raft protocol-ownership boundary
respected across all 35 tagged commits.
Three known_limitations recorded, all non-blocking: two are
design.md describing an originally-planned architecture that shipped
differently after reviewer-approved safety proofs (commit-source
switch stayed on the durable-majority barrier + own-term WAL_NOOP
gate rather than switching to raft_commit_index; AppendEntries send
side still goes through repl_broadcast, not raft_send_append_entries)
-- behavior is correct, docs just weren't updated to match. Third is
a stale TODO comment in ha.c whose own body already says IMPLEMENTED.
