 ## [1.2.0] — Unreleased
 
+### Raft cluster (C3a / C3b / ops)
+
+Production-ready path from config → election → SQL/DDL replication → ops.
+
+- **C3a — Networked bootstrap** — `BARADB_RAFT_PEERS=id@host:port`, election timer in production, heartbeat timer reset on AppendEntries, `raft_state.bin` persistence, partial-read-safe frames; E2E `tests/raft_e2e_test.nim` (3-node election + failover)
+- **C3b — SQL writes through Raft** — leader appends DML KV pairs and waits for majority commit; followers reject or **forward** via `BARADB_RAFT_CLIENT_PEERS`; apply path updates LSM + B-tree/FTS/HNSW + graphs; multi-statement write gate; writes only on `default` database
+- **DDL replication** — schema DDL (`CREATE`/`DROP`/`ALTER` table, index, view, graph, …) as `ddl` log entries; re-executed on apply; `CREATE`/`DROP DATABASE` excluded
+- **Leader write forwarding** — followers proxy DML/DDL to the leader SQL port when client peers are configured
+- **Safe log compaction** — soft cap `BARADB_RAFT_LOG_MAX_ENTRIES` (default 256); leader never discards past peer `matchIndex`; snapshot base (`lastSnapshotIndex`/`Term`) persisted
+- **Secondary-index point lookup fix** — index scans use `entry.lsmKey` (not the filter column as PK)
+- **Metrics** — Prometheus raft series on `GET /metrics` (HTTP = TCP port + 440); `GET /health` includes `raft` role/term/leader/lag/log size
+- **E2E writes** — `tests/raft_writes_e2e_test.nim` (schema, forward, index SELECT, failover)
+- **Docs** — `docs/en|bg/distributed.md`, `docs/superpowers/specs/2026-07-30-raft-cluster-status.md`

+3. DML/DDL on **default** DB only: leader appends, waits for majority, returns.
+4. Followers forward to leader if `BARADB_RAFT_CLIENT_PEERS` is set; else `not leader`.
+5. Apply updates LSM + secondary engines; DDL re-executes SQL on each node.
+6. Log soft-cap via safe prefix compact; metrics on HTTP port `BARADB_PORT+440`.

 # Networked Raft Bootstrap (C3a) — Design
 
-Date: 2026-07-30
-Status: Approved direction (user: "продължи"); implementation follows.
+Date: 2026-07-30  
+Status: **Done** (merged to `main`). See also `2026-07-30-raft-cluster-status.md`.
 
 ## Problem
 
-Raft in BaraDB is half-wired for real networking. `core/raft.nim` already has
-a TCP transport (`RaftNetwork`, binary framing, serialization, election-over-
-TCP proven by a test), but in production:
-
-1. `node.peerAddrs` is **never populated** (`baradadb.nim` creates the node
-   from `config.raftPeers` but never parses addresses) — all sends silently
-   no-op (`raft.nim:560-561`).
-2. **No election timer runs** — `tick` is only called from tests; a deployed
-   node never starts an election.
-3. `handleAppendEntries` on the wire path does **not reset the election
-   timer** — even if timers ran, followers would start elections despite a
-   healthy leader.
-4. Raft **state persistence is disabled** in server startup (`dataDir` not
-   passed to `newRaftNode`, `baradadb.nim:333`).
-5. Framing reads assume full TCP reads (`recv(4)`/`recv(payloadLen)`,
-   `raft.nim:604-611`) — partial reads corrupt the stream.
-
-Result: `BARADB_RAFT_ENABLED=true` today starts a listening socket that can
-never elect anyone. This phase wires what exists; it does NOT change the SQL
-write path (that is C3b) or add membership/snapshots (C3c).
+Raft in BaraDB was half-wired for real networking. `core/raft.nim` already had
+a TCP transport, but production never populated `peerAddrs`, never ran an
+election timer, did not reset timers on AppendEntries, skipped state
+persistence, and used unsafe partial frame reads.
 
 ## Goal
 
-A 3-node BaraDB cluster started with ordinary config elects a leader over
-TCP, maintains it with heartbeats, and re-elects after the leader is killed —
-verified end-to-end with real server processes.

-  `BARADB_RAFT_PEERS="n1@127.0.0.1:9473,n2@127.0.0.1:9474,n3@127.0.0.1:9475"`.
-  Bare entries (no `@`) keep current meaning (peer id, no address).
-- Parsing lives in `core/config.nim` next to the existing `BARADB_RAFT_*`
-  env handling (config.nim:174-179), producing `raftPeerAddrs: Table[string,
-  (string, int)]` on BaraConfig. Malformed entries fail startup with a clear
-  error (config-time, not runtime).
-- `baradadb.nim` startup copies `config.raftPeerAddrs` into
-  `node.peerAddrs` and passes the data dir (see §3).
-
-### 2. Election timer in production
-
-- A `timerLoop` async proc in `core/raft.nim` (next to `heartbeatLoop`,
-  raft.nim:625): every 50ms calls `tick(node)`; on election timeout calls
-  the existing `startElection` path (raft.nim:659-685), which sends
-  RequestVote over `RaftNetwork.send`.
-- `RaftNetwork.run` (raft.nim:633) starts `timerLoop` alongside
-  `heartbeatLoop` via `asyncCheck` — single place, no baradadb.nim changes
-  beyond startup wiring.
-- Wire-path timer reset: in the message-receive handling of `RaftNetwork`,
-  after a valid AppendEntries (or heartbeat) is processed, reset the
-  follower's election timer (`ElectionTimer.lastHeartbeat = now`) — wherever
-  the existing handler processes inbound AppendEntries, matching what the
-  in-process tests do manually.
-
-### 3. State persistence on
-
-- `baradadb.nim:333`: pass `config.dataDir` (or a raft subdirectory of it —
-  check what `newRaftNode` expects; `saveState`/`loadState` write
-  `raft_state.bin`) so currentTerm/votedFor/log survive restarts, per the
-  Raft spec (and the TLA models).
-
-### 4. Framing robustness
-
-- Replace the `recv(4)` / `recv(payloadLen)` assumptions with the existing
-  `recvExact`-style helper pattern used by the main server
-  (`core/server.nim:312-329` has `recvExact`/`recvExactWithTimeout` — mirror
-  the approach inside raft.nim; do NOT import server.nim into raft.nim).
-
-### 5. What does NOT change
-
-- SQL write path (ReplicationManager, server.nim) — untouched.
-- Raft state machine, message format, serialization — untouched (the TLA-
-  faithfulness tests pin them).
-- `applyCommand` hook in baradadb.nim — stays as-is; committed entries
-  (from tests / future C3b) still apply to the default DB.
-
-## Testing
-
-TDD where feasible; the headline test is end-to-end:
-
-1. **Config parsing** (unit, `tests/test_all.nim` or bugfix_test): peers
-   with and without `@host:port`, malformed entries error clearly.
-2. **Framing** (unit): partial-read feed of a serialized message through the
-   new read path (socketpair or chunked strings) — message reassembles.
-3. **E2E cluster** (new file `tests/raft_e2e_test.nim`): start 3 real
-   `build/baradadb` processes with raft enabled on distinct ports
-   (client/raft ports offset per node), wait for a leader (queryable how?
-   — simplest: each node logs its role; or a `RAFT STATUS` text command on
-   the client port if one exists cheaply — decide in the plan), kill the
-   leader, assert a new leader is elected within ~5s. Clean teardown.
-4. Existing suites stay green (`nimble test`, 659+ `[OK]`) — especially the
-   in-process raft suites and the 3-node election TCP test.
-
-## Risks
-
-- Election-timer/async interactions with the main server's async loop —
-  `RaftNetwork.run` already runs under `asyncCheck`; timerLoop follows the
-  same pattern. Watch for CPU spin (50ms sleep, not busy loop).
-- Port allocation in the E2E test (parallel CI) — use the same
-  time-derived port offset pattern as `tests/nimforum_smoke_test.nim`.
-- Timer reset wiring point: the inbound message path must reach the node
-  the timer ticks — same `RaftNode` instance, verified by the E2E test
-  (no spurious elections under a healthy leader).

 # SQL Writes Through Raft (C3b) — Design
 
-Date: 2026-07-30
-Status: Done (implemented on `feat/raft-sql-writes`).
+Date: 2026-07-30  
+Status: **Done** (merged to `main`). Extended by post-C3b work (DDL, forward,
+compact, metrics) — see `2026-07-30-raft-cluster-status.md`.
 
 ## Problem
 
 With C3a a real Raft cluster elects a leader over TCP, but SQL writes still
-bypass Raft entirely: they go straight to the local LSM and (optionally) to
-the legacy `ReplicationManager` (unconnected in production). Committed Raft
-entries can be applied (`applyCommand` is wired and invoked on commit), yet
-nothing ever calls `appendLog` from the write path.
+bypassed Raft: they went straight to the local LSM. Committed Raft entries
+could be applied (`applyCommand`), yet nothing called `appendLog` from the
+write path.
 
-## Goal
+## Goal (delivered)
 
-When Raft is enabled, SQL writes are committed through the Raft log before
-the client sees success:
+When Raft is enabled, SQL writes commit through the Raft log before the client
+sees success:
 
-- Leader: execute locally (constraints validated as today), append the
-  resulting KV pairs to the Raft log, wait for majority commit, then return.
-- Followers: reject write statements with a clear "not leader" error naming
-  the known leader; apply committed entries via the existing `applyCommand`
-  loop (raft.nim:195-215).
-- Non-raft deployments: byte-identical behavior to today.
+- **Leader:** execute locally, append KV pairs (`put` / `delete`), wait for
+  majority `commitIndex`, return.
+- **Followers:** originally reject with `not leader; leader is '…'`; with
+  `BARADB_RAFT_CLIENT_PEERS` they **forward** to the leader (post-C3b).
+- **Apply:** LSM + secondary B-tree/FTS/HNSW + in-memory graphs
+  (`applyReplicatedPut` / `Delete`).
+- **Non-raft:** behavior gated on `raftNode == nil`.
 
-Non-goals (C3c+): leader forwarding/proxy, read consistency levels,
-schema/DDL replication (DDL produces no keyValuePairs today — out of scope),
-membership, snapshots.
+## Design (as shipped)
 
-## Design
+### Write interception
 
-### Write interception point
+`core/server.nim` `executeQuery`:
 
-`core/server.nim:206-227` — the server-level `executeQuery` parses the AST
-(server.nim:213) and, after successful execution, already ships
-`res.keyValuePairs` to the ReplicationManager (server.nim:219-227). The Raft
-path slots into the same place with the same data source:
-
-1. Classify the statement right after parse: write = `stmt.kind in {nkInsert,
-   nkUpdate, nkDelete, nkMerge}` (DDL is out of scope; SELECT unaffected).
-   New helper `isWrite(stmt)` in `exec/params.nim` next to `isDDL`.
-2. If Raft is active for this server (`server.raftNode != nil`):
-   - Not leader (`node.state != rsLeader`): return error
-     `not leader; leader is '<node.leaderId>'` (or `no leader elected`).
-     The statement is NOT executed.
-   - Leader: execute as today. If `res.success` and
-     `res.keyValuePairs.len > 0`: for each `(key, value)` append one log
-     entry — `cmd = "put"` with data `key \x00 value`, or `cmd = "delete"`
-     with data `key` when value is empty (this is EXACTLY the format the
-     existing `applyCommand` in baradadb.nim:336-343 already consumes — no
-     format changes, frozen). Then wait until `node.commitIndex` reaches the
-     last appended index (see below) before returning `res`.
-   - The legacy `replication.writeLsn` hook is skipped when the Raft write
-     path handled the statement (no double shipping).
-3. Single-node raft (enabled, no peers): majority is self — appends commit
-   immediately; behavior is correct with negligible overhead.
+1. Classify every statement: `isWrite` / `isRaftDdl` (not only `stmts[0]`).
+2. If raft active and write/DDL: require **default** database + leader (or
+   forward).
+3. After success: pure DML → `appendWriteToRaft`; any DDL in batch →
+   `appendDdlToRaft` (full SQL re-exec on apply).
 
 ### Wait-for-commit
 
-No raft.nim changes (the state machine stays TLA-frozen). Poll from
-server.nim: after appending, `while node.commitIndex < lastIdx`: sleep 10ms,
-up to `config.raftWriteTimeoutMs` (new env `BARADB_RAFT_WRITE_TIMEOUT_MS`,
-default 5000). Commit advances on the 50ms heartbeat cadence via the
-existing `handleAppendReply`/`applyCommitted` path, so typical latency is
-one heartbeat. On timeout: return an error (`raft commit timeout`) — the
-entry may still commit later; documented limitation. Local execution already
-happened (it validates constraints and produces kvPairs) — leader double-
-applies via applyCommand on commit, which is idempotent for put/delete KV.
+Poll `commitIndex` outside the storage gate (`appendWriteToRaft` /
+`waitRaftCommit`); timeout → `raft commit timeout`.
 
-### Server wiring
+### Known v1 limitations (still true)
 
-`Server` gains `raftNode*: RaftNode` (nil by default) in core/server.nim;
-baradadb.nim assigns it when raft is enabled (the node already exists there).
-server.nim imports core/raft (no cycle: raft.nim does not import server).
+- Multi-DB raft not supported (`raft writes only supported on the 'default' database`).
+- `CREATE`/`DROP DATABASE` not raft-replicated.
+- Leader local execute before majority (timeout leaves local write; documented).
+- No InstallSnapshot full SM dump (safe log compact only).
+- No membership changes.
 
-### Known v1 limitations (documented in code)
+## Tests
 
-- Leader losing leadership between local execution and appendLog (narrow
-  race): appendLog returns the empty entry (index 0) — surfaced as a
-  `lost leadership` error; the local write already applied (uncommitted).
-- Transactional writes: kvPairs are emitted at COMMIT (executor.nim:970-979)
-  — the COMMIT statement is the raft-replicated unit (classify nkCommitTxn?
-  — resolve in planning: COMMIT's kvPairs flow through the same hook since
-  the existing replication hook already catches them).
-- DDL is not replicated (no kvPairs today).
-
-## Testing
-
-1. Unit (`tests/bugfix_test.nim`): `isWrite` classification for
-   INSERT/UPDATE/DELETE/MERGE vs SELECT/DDL.
-2. Follower rejection (in-process or E2E): write on a follower returns the
-   "not leader" error naming the leader; the statement is not executed.
-3. E2E (extend `tests/raft_e2e_test.nim` or sibling): 3 real nodes; write a
-   row on the leader via the Nim client (adaptors/nim/baradb_sqlite pattern
-   from nimforum_smoke_test); poll a SELECT on a follower until the row
-   appears (deadline ~5s — follower applies on commit via applyCommand);
-   write on a follower → rejected; kill leader → re-election → writes work
-   on the new leader.
-4. Full `nimble test` green (673+ `[OK]`).
-
-## Risks
-
-- Double application on the leader (executor + applyCommand): idempotent
-  KV semantics — verify put/delete idempotency holds for the value encoding
-  (same key → same value; delete of existing key).
-- `node.log[idx-1]` positional indexing in the leader commit loop
-  (raft.nim:407) — pre-existing, out of scope unless the E2E trips it.
-- Apply lag on followers (heartbeat cadence): tests poll with deadlines,
-  never fixed sleeps.
+- Unit: classification, append/timeout, apply indexes/graphs, compact, metrics
+- E2E: `tests/raft_writes_e2e_test.nim` (schema, forward, index SELECT, failover)
