First tried defaulting in_catch_up=1 in repl_add_standby — REVERTED: it broke the whole controller suite (commit-WAIT tests TIMEOUT 300s because a fresh standby no longer counts toward write quorum until convergence, and the unit tests don't run the heartbeat dispatch that would clear it). Correct fix: persist_wal_write_replicated now REJECTS a forward gap (lsn > current_lsn) with -EAGAIN instead of writing it — so a live broadcast that arrives ahead of the in-order catch-up is DROPPED (no write, no ack, no current_lsn jump), and the ACK-driven catch-up continuation re-streams from current_lsn so the log fills in order. ha_apply_single_entry + ha_apply_wal_catchup_entry treat -EAGAIN as a quiet skip (TRACE, no ack, no ERROR spam). Combined with bug-848 (advertise durable_floor == current_lsn-1) the catch-up always starts AT current_lsn so it is never spuriously rejected; only genuine forward gaps are.

The leader's library send path (`ha_read_wal_entry_at`, ha.c:1472-1476) and the standby's `logOk`/`on_get_entry_term` both source terms from `persist_entry_term` (in-memory index, legacy-0→WAL_LEGACY_TERM). The heartbeat catch-up streamer (`ha_stream_wal_to_standby`, config_repl.c) — the third consumer — was sourcing terms from raw on-disk `hdr.term` (0 for legacy entries). A standby's `prev_log_term=1` (normalised) ≠ streamer's `prev_log_term=0` (raw) → `logOk` rejects the new-term NOOP forever → `applied_lsn` stuck → primary re-streams every heartbeat cycle. Fix: all three `hdr.term` reads in the streamer replaced with `persist_entry_term(&persist, hdr.lsn)`; function gained a `const persist_t*` parameter. This is the pattern: every source of the per-LSN (term,index) tuple MUST go through `persist_entry_term`; NEVER read `hdr.term` raw from disk — it is not normalised. +- (2026-06-23, bug-854 FIXED) The `XCECLI_FAILOVER_CALL` retry loop classifies a status-0 reply from ANY reachable node as SUCCESS and returns — it only rotates on failure. But ctrlstatus is answerable in every role, so a standby always answers 0, making `xcecli_ctrlstatus` pin to the first reachable node forever. The outer `xcecli_ctrlstatus_primary` loop captures a redirect hint from the non-authoritative reply but never forces rotation to the next master — so the configured master list is never traversed. Fix: `xcecli_ctrlstatus_primary` now calls `xce_failover_rotate(ctx)` + `xcecli_ctx_recover(ctx)` under `failover.lock` on every non-authoritative reply; the floor of `max_attempts` was raised to `nmasters+1` to cover the full ring. General pattern: any outer retry loop that queries a role-agnostic status must **force endpoint rotation** on a non-authoritative reply — do not rely on the inner failover wrapper, because status-0 preempts it. - (2026-06-22, ha-term-safety task 3.1) The single primary-append seam is `ha_primary_log_append(cluster_t*,type,payload,len,&out_lsn)` (ha.c, decl ha.h ~333): packs the `raft_entry_blob_t` envelope and calls `raft_log_append(&c->ha.raft,...)` so the LIBRARY stamps `s->term` + assigns LSN + fires `on_persist_entry`. CRITICAL: `raft_log_append` returns `-EPERM` unless `s->role==RAFT_LEADER` — and `ha_do_promote`/the non-raft `ha_promote_to_primary` road sets `ha->role=CTRL_PRIMARY` but NOT `ha->raft.role` (only the raft election road via on_become_leader sets RAFT_LEADER). So `ha_primary_log_append` MUST have a `-EPERM`→legacy `persist_wal_async` fallback (stamping `ha->term` via persist_set_term first) or init-time/non-raft/engine-less promotion breaks. Retired the hand-rolled bypass by routing persist.c `wal_hook_append_classified` (RETAIN job/queue/worker hooks) + `persist_wal_sync_append` (WAL_JOB_SUBMIT WAIT) through `ha_primary_log_append` GUARDED on `p->cluster != NULL` — standalone persist (lib-level tests, `persist_init(p,&cfg,NULL)`) keeps the direct persist_wal_async path. `p->cluster` is the back-ref (persist.h, set in persist_init); ha.h is reachable in persist.c via `xce/cluster_def.h`. Co-tracking invariant `p->current_lsn == s->log_len + 1` holds because raft_init (2.5) seeds log_len from durable floor and every primary append advances both by 1. To make a controller TEST drive raft_log_append: `ha_init_raft` then set `c->ha.raft.role=RAFT_LEADER` + `c->ha.raft.term=T` directly (the raft-sim convention). on_persist_entry calls persist_wal_async (NOT the hooks) so no recursion. `ha_arm_own_term_gate` is static → test seam `ha_arm_own_term_gate_for_test`. Validation: pre-existing `test_wal_catchup_*` (7, bug-924 overlayfs) fail IDENTICALLY on baseline (git stash + rebuild proves it); every other group 0 fail. - (2026-06-20, waldump tooling) The `xce_test` binary (`src/controller/meson.build`) builds from `testsuite/test.c` ONLY + `libxce_dep` — it does NOT link `persist.c`/`job.c` (those are in the `controller_unit_test` target). The investigation doc's claim that xce_test "links persist.c/job.c" was WRONG. BUT capnp `read_Job` is generated into `controller.capnp.c` which IS compiled into `libxce`, so it's reachable transitively. To USE capnp/zlib symbols from test.c you must add `c_capnproto_dep` + `zlib_dep` to `xce_test_deps` (static-lib deps don't auto-propagate through `declare_dependency(link_with: libxce)`). For a zero-alloc jobid decode read `struct Job.jobid` directly after `read_Job` — skip the allocating `decode_Job`. WAL CRC reader template = `persist_test_durable_lsn_on_disk` (persist.c ~888): seg files `seg-%016llx.wal` under `/data/wal`, 40B `wal_entry_hdr_t`, crc32 over `WAL_HDR_CRC_SIZE`(=32) header bytes + payload, prev_crc chain, all-zero hdr = clean EOF (pre-alloc).

The ROLLING SIGKILL SOAK is host-verification-needed in-sandbox: rounds 1-2 PASS (jobs survive failover), then round 3 onward "no new primary elected within 40s" and every "DATA LOSS" report is a query against a cluster with NO live primary (same 5 jobs frozen, never re-acked). ROOT CAUSE of the collapse is the durability fix's OWN promotion fence working AS DESIGNED: ctrl-1 won PreVote for term=5, computed safe_committed_lsn=13, then `persist_recover_fatal_if_unrecoverable` FATAL-terminated ("recovery-truncated log ... no healthy peer reachable ... durable_floor_lsn=13 < hwm=13 ... terminating rather than serving divergent state, Req 2.4") — refusing to let a structurally-truncated node lead and overwrite the good timeline (exactly the bug-661 failure mode the fix prevents). Under aggressive rolling-kill+immediate-restart the fence repeatedly self-terminates recovering nodes → cluster drops below quorum → liveness collapse, NOT durable loss. PROOF it's not loss: committed entries still on disk after the run (ctrl-3 WAL has seg-1 + seg-15; ctrl-2 seg-1) and 0 live controllers at end. So the soak's exit=1 / "DATA LOSS" verdict is a HARNESS ARTIFACT (it equates empty-joblist-with-no-primary to loss) — the soak harness conflates election-stall liveness failure with durability loss. The deterministic flip is the must-have and passed; the live multi-round soak needs a real host (slower election timing, no sandbox reaping) to distinguish fence-driven safety self-termination from a true regression.

Those entries were acked by this node as a standby ⇒ committed by the prior leader. `raft_cb_become_leader` calling `persist_truncate_wal_above(safe_lsn)` destroyed them (granted `{self=47, peer=44}` → median 44 cut the leader's own committed 45..47), and `persist_truncate_wal_above` ALSO sets `committed_lsn=cutoff` (a commitIndex DECREASE) + clamps durable down. The leadership NOP then landed at LSN 45 (the rewound tip) under term+1, diverging vs peers still holding the old job at 45 → contradictory freshness denials (one node fresher by index, the other by term) → permanent prevote deadlock + committed-job loss. +- FIX shape: clamp the truncation cutoff to `max(safe_lsn, persist_durable_floor)` via pure helper `ha_promotion_truncate_floor` so truncate is a no-op on the leader's durable log. Do NOT clamp `safe_lsn` itself inside `ha_compute_safe_committed_lsn` — `promotion_safe_lsn` is also the behind-node fence HWM; inflating it to self's tip would make every node trivially pass its own gate. The deadlock was a SYMPTOM; the freshness gate is correct (it refused to elect a leader that would lose committed data). Same class as bug-795/bug-828 ("new leader truncates own committed entries"); bug-828 fixed grant-RECORDING so the median reflects the majority, bug-1060 fixes the remaining case where the median is below the leader's OWN tip. +- `persist_truncate_wal_above(cutoff)` is a NO-OP when `cutoff+1 >= current_lsn` (returns early, does NOT touch committed_lsn). Only when it actually cuts does it set committed_lsn=cutoff + clamp durable. So clamping the cutoff to >= durable tip makes it inert on a recovered leader (current_lsn == durable_tip+1). + +## Key Learning (2026-06-24, bug-1067) — AppendEntries has TWO terms; never conflate them +- Raft's AppendEntries carries (a) the HEADER/leader term — `term` arg of raft_on_append_entries_request, used for UpdateTerm + the stale-reject `if term < s->term → ae_reject_stale` — and (b) each ENTRY's STORED term (`entry_term` arg), used for logOk + on_persist_entry. The XCE library `raft_on_append_entries_request` already takes them as SEPARATE args; the controller adapter `ha_consume_append_entries` was setting `ae_term = entry_term` (the stored term). Correct for a LIVE append (leader appends at its current term ⇒ equal), but for CATCH-UP of a HISTORICAL entry written by a PRIOR leader, entry_term < current leader term ⇒ stale-reject of every historical entry ⇒ cross-term catch-up wedges forever (standby stuck, streamer retransmits). FIX: carry the leader's current term out-of-band per entry (`wal_catchup_entry_t.leader_current_term`, wire `WalCatchupEntry.leaderCurrentTerm @8`), stamped by `ha_stream_wal_to_standby` = ha->term, used as ae_term with fallback to entry_term when 0. +- DO NOT try to fix this receiver-side by using `s->term` as the AE term: a genuinely STALE leader (leader term < s->term) could then push divergent entries through (the stale-check is the ONLY thing rejecting it).

So registering the same hook twice = fires twice + survives one disable. Every WAL_JOB_SUBMIT was double-appended (byte-identical, adjacent LSN) because persist_start() (boot, unconditional) AND ha_register_persist_hooks() (PRIMARY promotion) both register persist_job_hook_fun with the same persist_t. The hooks_registered guard only stops ha_register from re-adding ITSELF — it's blind to persist_start's registration. +- FIX = make xce_add_hook idempotent on exact (fn,data): re-adding an active (fn,data) is a no-op; same fn + DISTINCT data still creates a 2nd slot (legitimate multi-closure, preserved by test). Chosen over "remove persist_start's registration" because MANY controller unit tests (test_e2e_checkpoint, test_ha_role_lifecycle, test_commit_barrier_reply:387 "persist_start registers the production hooks") DEPEND on persist_start registering the hooks and do NOT call ha_register — removing it would break that contract. +- ack gating: handle_jobsubmit (job.c) acks the client iff xce_run_hooks(AFTER_EVENT JOB_NEW) returns 0, and xce_run_hooks returns the LAST hook's rc.

The soak only ever kills ONE node (single-failover), so the surviving pair always contains a lower-index node that out-races ctrl-3. Confirmed: ctrl-3 had 0 CTRL_PRIMARY announcements but DID start 6 elections (it tries, always loses the race). No leadership-transfer/stepdown command exists in xce_test or ha.c, so leadership can't be handed over directly. +- HOW to force a specific (lowest-priority) node T to lead, DETERMINISTICALLY and loss-free (run-ha-soak.sh force_elect_node): exploit the RequestVote freshness gate (a behind node cannot win). P=current primary, S=third node. (1) kill S so it stops receiving entries; (2) submit a batch → commits on {P,T}, S now provably behind; (3) kill P → only T alive briefly (T holds ALL commits — they were on {P,T} — so nothing is lost); (4) restart the STILL-BEHIND S → quorum {T fresh, S stale}; S cannot catch up while there is no primary, so it stays freshness-fenced for the whole election → T wins deterministically (NOT by timing); (5) verify no loss, restart P, reconverge. KEY INSIGHT: a behind node can't catch up without a primary, and there's no primary during the election, so the spoiler is guaranteed fenced — this removes all timing-race flakiness. +- The soak now tracks SEEN_PRIMARY per node and the verdict ASSERTS all 3 led (PASS line: "all 3 nodes led (ctrl-1,ctrl-2,ctrl-3)"); a node that never leads is a FAIL. force_elect_node is generic (works for any
