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.

cdd446fc17 docs(specs): gap-analysis validation pass across all 9 HA-family specs 
Appended "Gap Analysis — Validation Pass (2026-06-09)" to each spec's
research.md with requirement-to-asset maps, status tags, and effort/risk.

Key outcomes:
- ha-repl-hardening: REOPENED with task series 7.1-7.7 — replication
  payload data plane is missing (snapshot chunks and WAL catch-up ship
  header-only; standbys converge on LSN without holding entity state)
- worker-join-refactor, resval-id-decoupling: marked implemented
  (all criteria re-verified, full test suite green)
- buglog: 335/336 (scheduler dequeue, open), 337/338/339 (fixed in
  previous commit); cerebrum Decision Log corrected (term-only vote
  deny was recorded as intentional but was a regression)

Captures all uncommitted work from ha-config-bootstrap,
ha-heartbeat-liveness, and associated spec/tooling updates:

- src: ha.c, ha.h, cluster.c, config_repl.c, myapp.c, raft.c —
  heartbeat liveness, RDHUP integration, committing phase fixes
- tests: test_ha_role.c, test_config_repl.c, test_ha_rdhup_integration.c,
  test_p1_integration.c, test_p3_hardening.c, scheduler test
- specs: election-iomgr-refactor, ha-heartbeat-liveness,
  ha-peer-connection-reuse, raft-library (new); ha-config-bootstrap
  and election-iomgr-refactor task/research updates
- tooling: .wolf/ state, ha/data cluster fixtures, raft/raft.tla,
  src/build symlink, xce-build skill update
