Conclave — a decentralized, database-free backend built on a from-scratch Raft consensus implementation.

Highlights

Raft consensus core — leader election, log replication, and commit, implemented from scratch on the Node standard library (no consensus/distributed-systems dependencies).
Log compaction — snapshotting + chunked InstallSnapshot to bound the log and catch up lagging followers.
Dynamic membership — add/remove nodes at runtime via joint consensus (Raft §6), with dual-majority safety.
Linearizable reads — opt-in ReadIndex barrier (?consistency=strong); fast eventually-consistent local reads by default.
Tamper-evident audit trail — the replicated log is hash-chained; altering any past entry breaks the chain.
Built-in platform concerns — structured logging, Prometheus metrics (incl. consensus signals), request tracing, idempotent writes, durable crash-consistent persistence, and leader forwarding.
Edge read replicas — a read-only client SDK (Node + browser) that tails the committed-log stream over SSE and serves reads locally (ADR-0023).
Pluggable application layer — bring your own deterministic StateMachine; the demo is a library book service.

~9.2k lines of source against ~8.6k lines of tests (consensus safety, failover, snapshots, membership, crash-consistency, read barriers, log backtracking).
