Rongsong Shen 05febbc9a7 docs(specs): gap re-validation 2026-06-24 (5 HA/raft specs) 
/kiro-validate-gap gap-focused sweep. Per-spec gap analysis written to each
spec's research.md (3 new, 2 appended), grounded in file:line evidence:

- config-upgrade-snapshot (new): real open gap — transport + (term,lsn) marker
  + COW substrate exist, but the entity-bearing snapshot PAYLOAD does not
  (16-byte LSN sentinel). HARD-blocked on entity-bearing-snapshots. Closes
  bug-857. Effort L (XL incl. blocker) / Risk High.
- raft-commit-safety (new): CLOSED — G4 Figure-8 commit (raft.c:733) + G6 vote
  freshness (raft.c:157) done, full sim coverage; the "(0,0) stopgap / broken
  build" concern is stale (build green, real vote tuple at cluster.c:435).
- raft-sim-conformance (new): mostly open — raft.tla is reference-only; only
  1 of 4 invariants (Log Matching) checked in code. Missing PRNG/replay,
  message-fault bag, scheduler, 3 invariant checkers, fault switches,
  scenarios. Effort L / Risk Medium.
- ha-repl-hardening (append): RESCOPE/superseded — 31/33 EARS closed; Req 2.3
  + Req 6 obsolete (CTRL_PRIMARY_COMMITTING removed). Residual: docs only.
- ha-convergence-recovery (append): done bar Task 8 (live E2E); bug-1028
  post-failover availability resolved 2026-06-23.

Skipped ha-elect-ctx-lifecycle (no requirements.md).
