Rongsong Shen 3c5185a5c3 feat(raft-log-replication): raft_on_append_entries_request UpdateTerm+logOk+accept (tasks 5.1-5.2, 6.1-6.3) ... Complete HandleAppendEntriesRequest (raft.tla:327) + UpdateTerm (raft.tla:406), implemented as one function to avoid a misleading partial handler. Fixed step order: UpdateTerm FIRST on every RPC incl. heartbeat (G5, strictly-greater, clears voted_for, persists, leader step-down fires on_become_follower) -> stale reject -> candidate step-down -> logOk (G2) -> reject if !logOk -> accept (already-have / conflict-truncate-then-repersist (G3) / append). Never advances commit, never does transport I/O. Review-applied: logOk now includes the explicit prev_log_index <= log_len bound (raft.tla:330 / Req 4.1) instead of relying solely on the 0-absent sentinel; added a candidate-equal-term-logOk-fails step-ordering test. 15 tests, ASAN green.		2026-06-21 16:18:02 +00:00
