Rongsong Shen 20e59d0b42 checkpoint: bug-851 root cause + raft TLA+ conformance spec family ... Investigation & fixes (failover committed-job loss): - root-cause bug-851 on an owned 3-node cluster: chaotic failover causes silent committed-prefix divergence (WAL hdr.term always 0; two leaders per term; no (term,lsn) reconcile). Evidence in repro-851/ + INVESTIGATION. - live-validated fixes 848/849/850 (recovery-on-promotion, advertise real applied_lsn, persist-layer contiguity guard); add waldump WAL inspector. Specs (strict raft.tla conformance — library owns the log): - TLA-gap-analysis.md: impl vs raft/raft.tla, gaps G1-G6. - raft-log-replication, raft-commit-safety, raft-sim-conformance: extend src/lib/raft to own log/commit/verification via callbacks (specs generated, cross-spec review passed). - ha-term-safety: controller-side adapter + config marker (R1-R7); design done. - config-upgrade-snapshot: R8 descoped here (deps entity-bearing-snapshots, bug-857). - roadmap + buglog (851/854/857) + .wolf knowledge updated.		2026-06-21 14:02:15 +00:00
