+
+# 14 — A3: Durable Raft term and vote state (deferred)
+
+## What to build
+
+Persist Raft `currentTerm`, `votedFor`, and log metadata to disk. In-memory-only term (~26) risks split leadership after tracker restart → duplicate settlement epochs.
+
+**Code refs:**
+
+- `packages/tracker/meshnet_tracker/raft.py` — `LogEntry.term` (~25–27), election state in `RaftNode`
+
+## Acceptance criteria
+
+- [ ] Term/vote persisted alongside tracker data dir
+- [ ] Restart resumes as follower/candidate with monotonic term
+- [ ] Test: kill leader mid-settlement, restart, no duplicate payout batch
+
+## ADR links
+
+- [ADR-0019](../../docs/adr/0019-money-path-consistency-multi-tracker.md) §3
+
+## Blocked by
+
+Alpha single-settlement posture
