Rongsong Shen	06135954ff	chore: baseline snapshot — prior-session work + ha-consistency-invariants spec family ... Pre-existing uncommitted work: ha-repl-hardening payload data plane (7.x), heartbeat liveness fix (Req 1.3), connection-reuse ASAN fixes, doc cleanup. New: ha-consistency-invariants umbrella (requirements/design/research) and its four implementation sub-specs (specs generated via batch, cross-spec review applied), steering roadmap + product.md Raft+CP decision.	2026-06-11 13:21:50 +00:00
Rongsong Shen	084244941b	chore(ha-wal-replication): mark tasks 4.1-4.2, 5.1-5.3, 5.5 complete in tasks.md ... Task 5.4 blocked (requires live /xce-deploy-ha cluster — manual only). Task 5.5: 308 assertions across 45 tests pass; ASAN leaks are pre-existing in election-iomgr-refactor tests, zero new leaks from this feature.	2026-06-10 11:54:34 +00:00
Rongsong Shen	566c91cd8b	feat(ha-wal-replication): standby WAL ACK reply (tasks 3.1-3.3) ... Standby sends WalAckReply via xce_reply after each successfully applied WAL entry. ha_apply_wal_catchup_entry signature extended with endpoint_t* and cluster_t* parameters. walackreplymsg union arm added to RequestReply capnp schema and xce_reply_t. Error entries skip ACK. Dispatch gate test confirms OPCode_walCatchupEntry allowed in CTRL_STANDBY/ELECTING/INIT.

Rongsong Shen	81dbc4d7b4	feat(ha-wal-replication): HA→replicator standby registration bridge (tasks 2.1-2.3) ... Register standbys with replicator on connect (election promotion + late-joiner), deregister on disconnect (vote err handler + standby err handler). repl_add_standby now idempotent (duplicate ep returns existing slot).
