fix(controller-test): clean_failover_preservation.sh runs again (bug-1721)
The script required a pre-generated <repo>/ha/data (cluster.bin + TLS
certs) that ee8473bd removed, and called deploy-ha.sh with that dir as an
extra argument; deploy-ha.sh now generates both into the deploy dir and
takes <binary> <top-dir> <peers>. It failed at its first precondition in
every checkout.

Behind that, both committed-LSN boundaries still assumed bug-845's doubled
submits (1 + 2*N_JOBS): the commit wait never reached it and walcompare
compared an LSN past every member's WAL. Since that fix each job is one
WAL entry, so the boundary is 1 + N_JOBS.

fix(controller): record standby state under its absolute peer index (bug-1891)
A promoted vote endpoint carries a peer index relative to the votes
array (which leaves out the primary); a late-joiner's heartbeat endpoint
carries the absolute index. repl_ack_decode_and_dispatch recorded state
reports under the raw index, so with ctrl-1 primary, ctrl-3's vote
endpoint (relative 1) and a rejoined ctrl-2's heartbeat endpoint
(absolute 1) shared standby_reported_*[1]. Each handler then acted on
the other's position over its own endpoint: the snapshot meant for the
empty, rejoining ctrl-2 went to the caught-up ctrl-3, and ctrl-2 never
caught up.

Resolve the absolute index with ha_repl_ack_abs_peer_idx (as the
WAL-ack branch already did) for the state report and for
ha_walack_on_ack, and size catchup_inflight by MAX_HA_CANDIDATES so
every absolute index fits.

fix(controller): cold start elects in ~1.7 s, not ~10 s; ctrlstatus appliedLsn on the primary (bug-1879, bug-1878)
bug-1879: on a fresh HA cluster the config-holding ctrl-1 started its
term-1 election before its peers ran; connect failures count as "no"
votes (bug-1423), so it lost at once and became a follower with no
leader. ctrl-2/ctrl-3 hold no config and are voters only (by design),
so nothing retried until ctrl-1's 10 s standby liveness timeout: every
cold start had no primary for ~10 s.
- ha_note_leaderless() marks a config-holding node that becomes a
  follower with no leader known; the liveness poll then retries the
  election (PreVote) after HA_LEADERLESS_RETRY_MS = 1 s, doubling up to
  heartbeat_timeout_ms. Primary contact or becoming leader clears it.
- ha_heartbeat_is_fresh() answers "no" while leaderless: last_activity
  then only holds the watchdog's arm time, and the failover gates took
  it for a live primary.
Live cold start: primary 1.7 s after the first node started (was ~10 s).

bug-1878: ctrlstatus_fill() reported ha->applied_lsn for every role, a
standby-only counter a primary never advances, so every primary showed
"appliedLsn: 0". A primary now reports persist->last_applied_lsn. The
controller-status design doc's "already correct in every role" note is
corrected.

Tests: 5 new in test_ha_failover_prevote.c, 1 new in test_ctrlstatus.c
(RED: expected 4900, was 0); controller suite 1256/0. HA soaks:
sequential 6 rounds PASS, chaotic 6 rounds PASS (zero divergence, zero
job loss).

fix: spurious errors/warnings from a pc13v HA deploy (bug-1872..1877)
- bug-1872 (worker): "Failed to find any disk statistics in
  /proc/diskstats" ERROR every 15 s on an NVMe-only host. The whole-disk
  filter guessed from the name and skipped anything ending in a digit or
  containing 'p' -- every nvmeXnY, mmcblkN, even sdp -- so io was never
  reported. diskstats.h now counts a device only when
  /sys/block/<name>/device exists (real disks; not partitions, loop, dm,
  md, zram), and a host with no disk warns once.
- bug-1873 (worker): "Failed to get worker pid" WARN on job start. MainPID
  reads 0 until systemd has forked the new transient unit; xcecd.c already
  retries, so the miss is DEBUG and the final failure names the unit.
- bug-1874 (scheduler): deprecation WARN for the legacy xce_sched_fcfs on
  every start, though builtin_fcfs is the picker. Registration still wraps
  a job_elect_fn plugin but no longer warns; selecting one warns once.
- bug-1875 (apiserver): "Not running as root -- PAM authentication will not
  work" with the default provider config_file; now only for provider pam.
- bug-1876 (controller): standbys logged "cluster_init_phase2 ... failed
  (rc=-22)" WARN every 3 s while waiting for the primary's config push,
  a state the function itself calls normal. It returns -EAGAIN for that
  wait; callers log it at INFO, other failures still WARN.
- bug-1877 (controller): "WAL/snapshot stored unencrypted" warned without
  looking. persist_path_encrypted() checks fscrypt (statx) and dm-crypt
  (sysfs dm/uuid CRYPT-, through LVM slaves); the warning stays when the
  storage is not shown to be encrypted (e.g. a plain /tmp).

Tests: worker diskstats_test (2 of 4 RED on the old filter with pc13v's
/proc/diskstats), controller test_phase2_cold_boot and
test_persist_encryption, scheduler picker tests, apiserver
TestRootWarning. Full ASAN build: all 113 suites pass (controller 319/0,
harness 141/0).

feat: acknowledged job start/finish/fail reports (bug-1741)
A worker reported job start, finish and failure with a fire-and-forget
OPCode_notify the controller never answers, so a report lost while the
worker stayed connected (the live incident: 6 of 7 finish reports in a
burst) left the job RUN forever; the rejoin resync (165fc158) only
recovers reports lost around a reconnect.

- controller.capnp: OPCode_notifyAcked -- the same NotifyData body,
  answered. A separate opcode because replies are matched through the
  client's single wbuf, not by sequence number: answering plain notifies
  would feed stale statuses to the next synchronous request.
- controller (cluster.c): do_notify_acked() applies the fact like
  do_notify, then waits on the commit barrier and replies 0 only once it
  is majority-committed. A barrier failure (the fact is still appended and
  retained) replies -E_XCE_NOT_READY, so the worker retries in place
  instead of rotating away from a healthy primary (cf. bug-1850). Admitted
  by the no-quorum fact-bearing gate like OPCode_notify.
- libxce: xce_notify_acked_req/xce_notify_acked (send, wait for the
  status) and xcecli_notify_acked (XCECLI_FAILOVER_CALL retry/failover).
  xcecli_notify_jobstart/jobfinish/jobfail use it; on -E_XCE_BAD_OPCODE
  (a controller predating the opcode) they fall back to the plain
  fire-and-forget notify, so workers and controllers can be upgraded in
  either order.
- Resends are safe: START/FINISH are duplicate-guarded and a repeated FAIL
  yields the same state.
- worker: logs a WARN when a report is still unacknowledged after the
  retry budget (the rejoin resync remains the backstop). These calls run
  on the worker daemon's IPC callback, so while the controller lacks
  quorum other jobs' IPC messages wait (buffered, not lost) up to the
  retry budget.

Tests: test_notify_acked_reply_only_after_commit and
test_notify_acked_withheld_replies_not_ready (no reply before the covering
ACK; -E_XCE_NOT_READY with the fact retained when ACKs are withheld).
Written with the opcode, so no separate RED run. Full /xce-build all:
111 suites pass; controller suite 1245/0.

fix(controller): resume at checkpoint+1 after loading a snapshot (bug-1870 follow-up)
Regression from 63fd3d2a (bug-1870), found by the --config-upgrade HA soak
(force-elect: "submit on {ctrl-2,ctrl-1} failed", ~640 standby NACKs;
bisected: 725301dd passes, 88c4310e fails).

load_snapshot() seeded current_lsn = checkpoint_lsn, but current_lsn is
the NEXT lsn to write and the snapshot covers 1..checkpoint_lsn. The
off-by-one was always there, hidden because every checkpoint also wrote a
WAL_CHECKPOINT marker ABOVE the checkpoint, so the WAL scan moved
current_lsn past it. With the marker gone, a standby whose WAL held
nothing above its config-marker checkpoint (LSN 11) recovered with
current_lsn=11: its raft layer counted entry 11 as held (ae_already_have,
not written), and persist_wal_write_replicated() then refused entry 12 as
a gap (ae_append_persist_fail) on every resend -- stuck at 11 forever.

Both of load_snapshot's commit points now set current_lsn =
checkpoint_lsn + 1, matching the apply-side catch-up path (lsn + 1).

New test_recover_from_snapshot_without_wal_resumes_after_it (RED before:
current_lsn 3, not 4). Two snapshot-entity tests asserted the old
current_lsn == checkpoint_lsn and now expect +1. Controller suite 1245/0.

fix(controller): a queue added by a live config upgrade exists without a restart (bug-1469)
build_queues() only ran at boot, so a queue a live config upgrade added
had no runtime object in c->qmgr (and the scheduler/apiserver never heard
of it) until the controller restarted. The checkpoint-ordering half of
bug-1469 was fixed in 959b0cda; this is the remaining half.

- reconcile_config_queues(c, notify): creates every queue in the active
  config that has no runtime object, leaves existing ones untouched,
  returns the number created.
- config_activate_committed() calls it (with notify) after every
  successful activation -- verified-marker and no-marker paths alike.
- persist_notify_queue_updated_no_wal(): fires HOOK_DETAIL_QUEUE_UPDATE
  under the t_apply_seam_notifying guard, so the scheduler/apiserver are
  told while no WAL_QUEUE_CTRL is appended -- config queues are
  config-owned, built on every member from the committed config.
- build_queues() now delegates to it without notify, so boot and
  activation are idempotent in either order.

New test_config_queue_reconcile.c (RED before: the added queue was never
created): creates the added queue, leaves the existing object untouched,
notifies once, and a second reconcile/build_queues adds nothing.
Controller suite passes.

fix(controller): scan standby_endpoints by capacity, not count (bug-1474)
Root cause of the "spurious duplicate reconnect" (angle a): zarray_del()
NULLs the slot and decrements count without compacting, so a live entry
can sit at any index < caps. Every standby_endpoints loop bounded by
`count` missed it. Live evidence (--config-upgrade-wal-trim soak,
2026-09-26): ctrl-2 won, promoted vote eps [ctrl-1 (dead), ctrl-3]; the
dead one's removal left [NULL, ctrl-3] with count 1, so the primary

- stopped heartbeating ctrl-3 (primary_heartbeat_fn's send loop),
- re-dialed it ("peer[2] not connected -- initiating outbound connect"
  9s later, for a peer that never dropped) and registered a second,
  "late-joiner" channel that burned a MAX_STANDBYS repl slot,
- could not evict the stale channel (on_standby_connected's dedup scan),
- and skipped it in config pushes and the ctrlhello broadcast, where a
  hole below count also handed endpoint_ref() a NULL.

The re-dial landed in the freed slot 0, which is what made ctrl-3 visible
again -- the "spurious" reconnect was masking the lost heartbeats.

All index scans of standby_endpoints (ha.c heartbeat, sweep, dedup, two
removals; cluster.c removal and ctrlhello; config_repl.c push collection)
now run to `caps` and skip NULL slots; the push collects exactly the
non-NULL entries. `count` stays where it means "how many connected".

New test_reconnect_dedups_channel_behind_deleted_slot (RED before: the
stale channel behind the hole was never evicted). Controller suite 1241/0.

fix(controller): run the become-leader tail on a task class that may block (bug-1433)
A winning RequestVoteReply is dispatched through peer_ctrl_classify, which
returned VTASK_LIVENESS for all peer-control traffic -- the never-blocks,
never-admission-gated class. The reply runs raft_cb_become_leader, whose
tail persist_apply_pump_run_sync() does bounded blocking WAL pread()s (it
cannot be made async without reopening the bug-1043-family job loss on a
freshly promoted primary). The fdatasync half of bug-1433 was removed in
40f510fb; this pread was the tracked residual.

peer_ctrl_classify now returns VTASK_LIVE_BLOCK while the node is
CTRL_ELECTING -- its peer-control traffic is then vote/PreVote replies,
election work like inbound RequestVote, which already uses LIVE_BLOCK.
As PRIMARY/STANDBY the traffic is WAL/config ACKs and stays VTASK_LIVENESS,
so a quorum of acks is never admission-gated (R4.5); a candidate has no
commit to advance.

New test_peer_ctrl_classify_vote_replies_while_electing (RED before).
Controller suite 1240/0.

fix(controller): a worker join that fails its commit barrier leaves nothing bound (bug-1728)
"ERROR incorrect worker idx -1" on every node after a worker-join commit
timeout (during a PreVote/election) was the visible end of a real
dangling pointer. init_worker/rejoin_worker bind the endpoint to the
worker (apply_join_state: w->ep = ep, UNAVAIL cleared) before the commit
barrier; on barrier failure handle_worker_join returned without setting
priv->u.idx, so when that connection closed handle_endpoint_error saw
idx -1, logged the ERROR and never ran handle_worker_leave -- the worker
kept w->ep pointing at the freed endpoint, available for dispatch, until
it rejoined.

- handle_worker_join: on barrier failure, clear w->ep (if still this
  endpoint) and mark the worker unavailable, as if the join never
  happened; the worker retries its join.
- handle_endpoint_error: an idx -1 worker endpoint is now the legitimate
  "closed before its join completed" case -- WARN, nothing to clean up.

test_worker_join_withheld_acks_replies_error also asserts the worker is
unbound and unavailable after the -ETIMEDOUT reply (RED before).

fix(controller): offload demotion convergence and catch-up streaming by default (bug-1450, bug-1451)
f88e4ef4 moved ha_demotion_convergence_fn's WAL truncate + self-restart
and ha_catchup_continuation_fn's WAL streaming off the delaymgr thread
(which drives heartbeats and election timeouts cluster-wide) onto the
slow lane, but left both flags OFF: flipping them ON hung pre-existing
unit fixtures that demote a primary or trigger catch-up without ever
starting c->slowlane -- the work was queued in a lane with no workers and
never ran.

- slowlane_is_started(): true while the lane has live workers.
- Both dispatchers run inline when the flag is OFF *or* the lane was never
  started. Production always starts the lane, so it always offloads; the
  lightweight fixtures keep their old inline behaviour, and neither
  one-shot action can be silently dropped.
- g_drive_async_demotion_offload / g_drive_async_catchup_offload now
  default to 1. The offload tests save and restore the previous value
  instead of forcing 0.

New test_catchup_offload_without_started_lane_runs_inline (RED before: the
catch-up body never ran, the stream gate was never reached). Controller
suite 1239/0 with both offloads ON by default.

fix: the controller is the ground truth for job state on scheduler rejoin (bug-1860)
A job the controller requeued to PEND while the scheduler was disconnected
stayed RUN (with its old allocation) in the scheduler forever: the
bug-1812 guard in core_events.c's JOBS_PUSH merge refused any non-RUN,
non-terminal resync claim over a job holding a real allocation, because
it could not tell a genuine requeue from a push built before the
scheduler's own fresh dispatch.

Design (per review): the scheduler persists nothing, so on rejoin the
controller's state wins, and the race the guard protected against is
closed where the truth lives:

- scheduler JOBS_PUSH: the bug-1812 refusal is removed; the controller's
  state replaces the scheduler's and its allocation is released. The
  terminal-is-permanent and phantom-RUN (RUN without allocation data)
  guards stay.
- controller dispatch_a_job_(): refuses a job that is not PEND (RUN or
  finished) before any worker is touched -- previously nothing checked,
  so a stale second dispatch would start a running job again (or, through
  a retryable failure, requeue it). The job is left as is, no WAL fact,
  and its true state is re-sent (HOOK_DETAIL_JOB_UPDATE). A PEND job with
  a leftover allocation stays dispatchable.
- scheduler JOB_UPDATE: a RUN report carrying the controller's committed
  allocation is adopted, so a corrected job is never RUN with nothing
  charged.

Tests (all RED before): test_jobs_push_duplicate_jobid_controller_pend_
wins_over_local_run (replaces the bug-1812 test that pinned the
refusal), test_job_update_run_adopts_controller_allocation,
test_dispatch_of_non_pending_job_is_refused. Two tests that seeded a RUN
job to reach retry branches (a precondition their own headers called
unreachable) now use the real paths: the counter-reset test requeues via
record_job_reconcile_pending_fact() first; the disconnected-worker RUN
test asserts the refusal contract.

Controller suite 1238/0, scheduler 87/87. HA soaks: chaotic 6 rounds PASS
(0 divergence/loss, 6 worker-resync jobs), sequential 6 rounds PASS
(SIMVERIFY 7 files, 0 mismatches). The race did not occur in either run
(0 refusals logged), so the new paths are proven by the unit tests.

fix(controller): resource hooks only carry values the controller accepted (bug-1583)
do_update_resvals() fired the AFTER_EVENT HOOK_DETAIL_RESOURCE_UPDATE with
the raw client xce_resval_list_t. update_resval_list() rejects unknown
resource names (-ENOENT) but only logged it, so both listeners -- the
scheduler push and the apiserver store (apiserver_resource_hook_fun ->
handler.go) -- received names the controller had rejected, and the
apiserver stored them.

- update_resval_list() takes an optional `applied` view (caller-sized,
  borrowed pointers) and fills it with just the accepted items.
- do_update_resvals() hands that view to the AFTER_EVENT hook, and skips
  it when nothing was applied. The request still owns every item.

New test_update_resval_list_reports_only_applied_items (RED before: both
items reported). Controller suite 1237/0. Live /xce-test-resources with
mem=5 totally-fake-resource-xyz=1: mem MATCH at controller, scheduler and
apiserver; the fake name is rejected at injection and appears 0 times in
scheduler.log / apiserver.log (verdict FAIL by design, for the rejected
name).

fix(controller): job_ctrl lock/reference and dispatch retry requeue (bug-448, bug-1626, bug-1631)
bug-448: job_ctrl() took a reference on the job but only one error path
released it; every successful call leaked one (refcount 1 -> 3 after two
calls). It is now released on every exit path, including the key_find
rc<0 one.

bug-1626: job_ctrl()'s not-started branch changes the job (mark_job_update
/ mark_job_fail -> apply_job_*_transition, which require RTTI_LOCK_WRITE)
while holding only RTTI_LOCK_READ, so it could run concurrently with
readers. It now takes the write lock. (dispatch_a_job_ already did.)

bug-1631: dispatch_a_job_()'s four retryable-failure branches never reset
state/allocs, correct for a first dispatch (still PEND) but not for a job
that had already been dispatched once: it stayed RUN holding its old
allocation. Each branch now calls record_job_reconcile_pending_fact() --
a no-op without a WAL fact for a PEND job; for a RUN job it returns it to
PEND, releases allocs and appends a durable WAL_JOB_UPDATE -- and notifies
after unlocking when it applied, the same pattern as the resync reconcile
path (cfe66dde). Not reachable until something re-dispatches RUN jobs
(e.g. preemption), fixed now so it is correct when that lands.

- job_get_refcount() (jobj.c) read accessor for the leak test.
- test_apply_pump.c: test_job_ctrl_releases_its_job_reference and
  test_job_ctrl_mutates_not_started_job_under_write_lock (both RED before).
- test_dispatch_fail_retry.c now asserts PEND + allocs released after a
  post-success retryable failure (RED before).

Controller suite 1236/0; all 111 meson suites pass.

fix(controller): checkpoints no longer punch a hole in the replicated log (bug-1870)
persist_checkpoint() and persist_checkpoint_marker_triggered() wrote a
local-only WAL_CHECKPOINT marker that consumed an LSN of the replicated log
(current_lsn++) but was never replicated. A checkpoint taken by one member
only -- the primary's periodic max-wal-records checkpoint, or the one before
a snapshot send -- left a hole no standby had: the leader's next entry
carried prev_log_index = the marker's LSN, logOk failed on every standby
forever, commits timed out and writes stalled ("could not submit 110 jobs"
in the --force-snapshot soak; reproduced on the pre-bug-1867 baseline). Even
the config-marker checkpoint, taken on every member, stamped the marker with
each member's own current_lsn at apply time, which need not agree.

Nothing reads the marker except to skip it, so checkpoints simply stop
writing it. The recovery, streamer and bug-1475 log_len skip paths stay, for
WALs written by older binaries; persist_test_write_legacy_checkpoint_marker()
(XCE_TESTING only) reproduces such a WAL for the tests that cover them.

- new test_bug1870_leader_only_checkpoint_leaves_no_log_hole (RED before):
  a leader-only checkpoint takes no LSN and a standby that never
  checkpointed catches up past it via the real streamer/receive path.
- test_checkpoint_writes_marker_to_wal inverted to ..._writes_no_marker_...
- bug-1475 x2 and the apply-correctness trailing-marker test now build
  their legacy marker explicitly.

Controller suite 1234/0. HA soaks: --force-snapshot PASS (113 jobs, real
snapshot install -- also live-verifies bug-1867), --config-upgrade-wal-trim
PASS, --sequential 6 rounds PASS (SIMVERIFY 7 files, 0 mismatches).

fix(controller): checkpoints keep a job's exit code (bug-1867)
The capnp Job struct -- the checkpoint/entity-snapshot form of xce_job_t --
had no exit-info field, so capnp_encode_job() never wrote job.exit_info
and a job restored from a snapshot (instead of WAL replay) came back with
exit_info NULL, for DONE/EXIT and failed jobs alike. bug-1689/bug-1754
made the WAL facts carry the code; anything older than the last
checkpoint's WAL trim still lost it.

- controller.capnp: struct JobExitInfo $C.mapname("job_exitinfo_t")
  { exitcode }, and Job.exitInfo @12 $C.mapname("exit_info"). The
  generator now emits encode/decode/free for it inside encode_Job /
  decode_Job / free_Job; restore_job()'s create_job() already takes
  exit_info via MOVE_PTR. Null stays null (no fabricated exit 0). A new
  ordinal, so older snapshots/recordings decode with exit_info NULL.

New test_snapent_checkpoint_exit_info_roundtrip (RED before): exit codes
0 and 137 and a NULL survive both the raw checkpoint frames and a real
persist_load_snapshot restore. Full /xce-build all (asan): 111 meson
suites, 0 failures; all Go packages pass.

Not live-verified: the --force-snapshot HA soak cannot reach its snapshot
step because of a pre-existing checkpoint-marker replication stall,
reproduced on the baseline without this change (bug-1870).

fix(controller): persist a failed job's finish_time through WAL_JOB_FAIL (bug-1747)
The FAIL half of bug-1747: apply_job_fail_transition() stamps
finish_time = time(NULL) at APPLY time, and WAL_JOB_FAIL carried no time,
so a failed job's finish_time changed on every restart replay / standby
catch-up, and a worker-reported failure found on rejoin could never keep
the worker's own time.

- WAL_JOB_FAIL's trailer grows to int32_t code + uint64_t finish_time
  (seconds). Decoded by length: 16 B (pre-bug-1754), 20 B (code only,
  bug-1754) and 28 B (code + time) all apply as before for what they carry.
- record_job_fail_fact_at(c, job, failinfo, finish_time_ms), the fail-side
  sibling of record_job_finish_fact_at(): 0 = receipt time. on_job_fail()
  uses receipt time; resync's finishedFail branch passes the worker-
  reported finish_time_ms (Req 4.2 now holds for failures too).
- Both apply seams adopt the wire time after the transition.

fix(controller): persist a failed job's exit code through WAL_JOB_FAIL (bug-1754)
A worker reports every nonzero job exit as a FAIL (xcecd_job_finished ->
xcecd_notify_job_fail(jobid, stage, exit_code)), not a FINISH. The deferred
WAL_JOB_FAIL fact carried only {jobid, STAGE_FLAG|stage} and no apply seam
touched job.exit_info, so exit_info stayed NULL for every failed job, live
and after replay, and HOOK_DETAIL_JOB_FAIL subscribers saw code 0.

- persist_submit_job_fail_fact(): header + int32_t code trailer, used by
  record_job_fail_fact(). Old entries (no trailer) decode as before.
- apply_job_fail_exit_code(): records the code in exit_info for pre-exit
  stages only; a POST_EXEC code is the script's and leaves exit_info alone.
  Kept out of apply_job_fail_transition() so mark_job_fail()'s internal
  -errno failures (not replayed with a code) stay live/replay consistent.
- Both apply seams adopt the code. apply_wal_entry()'s WAL_JOB_FAIL case
  also stops assigning the wire state 0 for STAGE_FLAG entries and runs the
  real transition, as apply_committed_entry() already does.

New test_wal_job_fail_fact.c (5 tests, 3 RED before the fix); the two
test_worker_resync.c assertions that pinned exit_info == NULL now assert the
worker-reported code. Controller suite: 1228 tests, 0 failures.

fix(controller): never close() the primary channel's raw fd (bug-1865)
handle_ctrlhello stored the netio endpoint's fd (primary_ctrl_fd = ep->fd)
and ha_on_primary_ctrl_fd_rdhup close()d it in three branches. netio owns
that socket and closes it on endpoint teardown, so by the time the
liveness poll fired the RDHUP the number could be reused -- in a chaotic
soak by the standby's WAL segment: HA's close() shut the WAL, fdatasync
failed 2305 times (EBADF, then EINVAL once a socket took the number),
durable_lsn stuck, and one round's jobsub failed EIO.

handle_ctrlhello now also holds a reference on the endpoint
(primary_ctrl_ep), which keeps its socket open and its fd number ours.
ha_drop_primary_ctrl_conn() replaces the raw closes: shutdown() the
still-owned socket so netio sees the hang-up and tears it down itself,
then release the reference. A bare fd with no endpoint is only forgotten.

Test test_rdhup_never_closes_an_fd_netio_already_released: real
ctrlhello -> netio teardown -> file opened on the freed number -> RDHUP;
the file was closed before, survives now. test_rdhup_closes_and_nulls_fd
updated to the new contract (peer reads EOF, fields cleared). Controller
suite 5/5.

fix(controller): stop a failed test from hanging the unit suite (bug-1429); mkstemp for upgrade temp file (bug-1861)
A failing TEST_ASSERT longjmps out and skips the fixture teardown, leaving
the commit engine's sweep thread and persist's fsync_worker asleep on a
static struct. The next test re-inits it underneath them, corrupting the
condvar, and a later teardown blocks in pthread_cond_destroy/join until
the 300s meson timeout. The failure line itself was lost because stdout
was fully buffered.

- controller_test: line-buffer stdout; tearDown() reaps what a failed test
  leaked via new XCE_TESTING registries (persist_test_reap_unstopped, then
  commit_test_reap_unfinalized_engines -- persist_stop before engine fini).
  Clean run reaps 0; an injected failure now fails in 2s instead of hanging.
- persist: flusher_flush_once reports only its own durable advance, so
  fsync_worker no longer re-fires the durable callback for an advance a
  concurrent persist_flush made (flaky "must not re-fire" test). Regression
  test test_flusher_pass_does_not_claim_concurrent_flush_advance.
- tests: jap observer is atomic and waits (bounded) for a continuation that
  may resolve on the flusher thread; pump catch-up tests wait for trailing
  replies instead of a single scan.
- config_repl: upgrade decode temp file via mkstemp instead of a
  pthread_self()-derived /tmp name (same value across processes, opened
  without O_EXCL -- collisions and a symlink target).

Verified: controller_unit_test 1222/1222; 24 parallel runs (6x4), no
hangs or ASAN errors.

fix(controller): string resvals own their bytes -- rejoin use-after-free killed new primary (bug-1851)
update_val_res() memcpy'd the xce_val_t into w->host.resvals, so the
"type"/"model" string resources aliased the interned xstrings owned by
w->host.attrs. rejoin_worker() drops the old attrs strings, then
apply_join_state() -> resync_arm_round() resolves the previous join's
still-outstanding round, firing the worker hooks before
add_hostattrs_resvals() re-seeds resvals; the apiserver hook's
collect_resval() strdup()ed the freed hostmodel. Live: a newly promoted
primary died ~8s after election during an HA soak.

A string resval now stores a private strdup (taken before the old copy is
freed), and the owning arrays free their entries: host.resvals gets
kill_resval (replacing the FIXME NULL killer) and c->sharedinst's
resval_obj_killer (previously a no-op) frees the string and the value --
both also leaked every xce_val_t before. Also closes the same alias for
worker-reported string resvals and config values.

Regression test: test_rejoin_worker_string_resvals_survive_outstanding_round
(RED reproduced the live ASAN stack; GREEN after). meson test 109/109.

fix(controller): resync_resolve_round never told scheduler RECONCILING cleared (bug-1841)
Worker-rejoin-resync sets XCE_WORKER_RECONCILING and pushes it to the
scheduler, which correctly freezes that worker's resInUse mid-reconciliation
(bug-1799/1801). But resync_resolve_round() only cleared the bit on the
controller's own worker_t, never notifying the scheduler -- so once a
rejoin round resolved, the scheduler's copy stayed RECONCILING forever,
permanently freezing that worker's resource accounting even after every
job on it finished. Live-observed via a replay capture: a 22-slot worker
stuck at used=22.00 for the rest of the run with zero RUN jobs left.

Added persist_notify_worker_status_updated() (mirrors bug-1679's job-side
persist_notify_job_updated_already_persisted()) and call it from
resync_resolve_round() so HOOK_DETAIL_WORKER_UPDATE fires without a
spurious WAL append. TDD: new spy-hook regression test, RED confirmed
against the unfixed code, GREEN after the fix. Full controller_unit_test
suite: 1220 Tests, 0 Failures, 0 Ignored.

fix(controller): standby-endpoint err handler freed ep->data under a live vtask (bug-1839)
Live 3-node HA soak crashed xce_controller: SIGSEGV in
peer_ctrl_msg_handler_inline (ha.c:7035) dereferencing a NULL
ep->data. gdb analysis of the actual core dump showed the endpoint
itself fully alive (refcnt=191964, tearing_down=0) while ep->data had
been synchronously freed and nulled by standby_ep_err_handler_primary,
the endpoint's err_handler, with zero coordination with the vtask pool
that was concurrently dispatching a peer-control message for the same
endpoint (g_drive_async_peerctrl_dispatch_enabled defaults ON).

The sibling handlers (vote_ep_err_handler, pre_vote_ep_err_handler)
already avoid this exact hazard, with an explicit comment: "Do NOT
free vctx here -- peer_ctrl_msg_handler may still reference ep->data."
standby_ep_err_handler_primary was never updated to the same
discipline when the vtask-pool dispatch machinery (bug-1197/bug-1298)
was introduced.

Fix: route standby_ep_err_handler_primary through the same
already-tested vote_ep_teardown_async() deferred, per-endpoint-FIFO-
serialized teardown that vote-endpoint demotion already uses, plus an
idempotency guard (endpoint_is_tearing_down) since the old "ep->data
== NULL" reentry check no longer applies once the free is deferred.
Also fixes a second-order double-unref this surfaced in
on_standby_connected's stale-duplicate eviction path, caught by ASAN.

TDD: two new tests prove the teardown is deferred until an in-flight
same-ep vtask completes, and that a repeated error callback on the
same endpoint is a safe no-op. Full controller suite: 1219/1219, zero
regressions.

Also logs bug-1840 (a separate scheduler heap-corruption crash from
the same soak run) as not-fixed pending an ASAN reproduction -- a
non-instrumented core dump cannot localize glibc's malloc_consolidate
abort back to the actual out-of-bounds write.

fix(controller): CtrlHelloRequest.key Data field crashed HA leader election (bug-1835)
CtrlHelloRequest.key was declared `Data` in controller.capnp. This
project's capnp-c backend silently no-ops encoding of Data-typed fields
without zero-initializing the caller's local struct, leaving an
uninitialized capn_ptr that write_CtrlHelloRequest unconditionally wrote
to the wire -- SIGSEGV in capn_setp/copy_ptr. Hit live: ctrl-1 won its
Raft election and crashed calling ha_send_ctrlhello_to_all_standbys().

Same bug class as bug-1504/bug-1505, both already fixed by switching the
field from Data to List(UInt8); bug-1505's own writeup had flagged
CtrlHelloRequest.key as a known-but-unfixed instance. Applied the
identical fix here: Data -> List(UInt8) + keyLen companion in the schema,
uint8_t*/key_len in typemap.h. The field is unused in production (always
NULL), so no consumer code changed. Added a round-trip regression test
covering both the NULL-key production shape and real key content.

fix(controller-status): ctrlstatus_fill must prefer a live registry slot over a stale disconnected one (task 8.6, bug-1819)
Found live during task 8.5's optional catching-up-observation attempt:
a killed-then-reconnected standby can end up occupying a NEW
replicator_t.standbys[] slot while its OLD slot (host/port still
populated, ep == NULL) also matches the same configured peer.
ctrlstatus_fill's primary-side peer-status loop stopped at the first
host:port match, so it permanently reported that peer dead even
minutes after it had genuinely reconnected and fully caught up --
violating Requirement 13.3's "true, currently-known connection status"
guarantee.

Fix: scan all MAX_STANDBYS slots for a given peer and prefer any slot
with ep != NULL over a slot with ep == NULL; fall back to dead only
when no matching slot is live. Read-only, lock scope unchanged from
task 8.2.

TDD RED->GREEN (1216 Tests: 2 Failures -> 0), independently reproduced
by the reviewer (exact RED replay) plus two independent live
kill/backlog/restart/poll cycles on separate fresh clusters, both
confirming the previously-stuck standby now converges to ok.

feat(controller-status): source per-controller connection status in ctrlstatus_fill (task 8.2)
Populates CtrlPeer.status (added in task 8.1) inside ctrlstatus_fill's
peer-building loop: self always reports ok; a primary responder sources
every other peer from the live replication connection registry
(replicator_t.standbys[], host+port matched, reusing
repl_active_standby_count's ep!=NULL && !in_catch_up predicate) --
dead/catching-up/ok; a non-primary responder reports unknown for every
non-self peer. A self-identity mismatch (pre-existing misconfiguration)
logs one WARN and falls through to the normal non-self sourcing rather
than forcing any peer to ok. Read-only: a bounded lock-protected scan,
no state mutation.

TDD: 3 new tests (primary-sourced-from-registry, standby-unknown-except-
self, self-mismatch-falls-through) plus an extended no-mutation
assertion; RED->GREEN independently reproduced by the reviewer.

The primary echoes its own last_known_elected_at_ms on every outgoing
heartbeat (threaded through xce_ha_heartbeat_req's existing scalar-arg

processing a received heartbeat (ha_consume_heartbeat_committed, the sole
production call site) stores it unconditionally into its own
last_known_elected_at_ms, reconcile-free -- no other HA field moves.
ha_observe_heartbeat_committed itself is untouched; the new store sits
next to its call site, not inside it.

every early-return refusal path in raft_cb_become_leader (first-boot
phase2 failure, the Live Apply Resource Fence re-check, the promotion
eligibility gate, config-serve-fenced, upgrade-materialization-fenced).
Purely observational: does not change whether/when a promotion succeeds
or is refused. Three new tests (2 positive, 1 negative) prove placement:
a refused promotion leaves the field at its pre-attempt value.

fix: repoint stale controller/xce_test path references to harness/xce_test
Follow-up to the xce-harness-component spec, which relocated xce_test
from src/controller/testsuite/ into a standalone src/harness/
component (commits cf55d691..cf380750). These four files were outside
that spec's own file boundary (owned by other specs / general tooling)
so were deliberately left alone at the time, but their hardcoded
default path and error-message advice were now stale and would have
misled anyone who hit them:

- .claude/skills/xce-build/SKILL.md: added `harness` to both component
  lists (frontmatter description + args section), and replaced the
  "controller always builds xce_test too" claim with an accurate
  description of the harness component, its own build command, and
  the accepted Meson test-runner quirk (bug-1806) that can still
  transitively rebuild xce_test as a side effect of another
  component's default-profile test run.
- src/controller/testsuite/test_rcfile_integration.sh (owned by the
  xce-test-rc-file spec): XCE_TEST_BIN default and failure message.
- src/controller/testsuite/clean_failover_preservation.sh (owned by
  ha-term-safety task 5.2): same.
- src/tools/test-commit-durability.sh: same, plus its header comment.

src/harness/testsuite/, and re-create their executable()/test() blocks
verbatim in src/harness/meson.build under suite 'harness' (task 1.1 had
already fully deleted them from src/controller/meson.build, not just
moved them, so these had been orphaned on disk since that commit).
Fix test_joblist_display.c's ctrlstatus_fmt.h include path to the
xce/ location promoted in task 1.2.

Verified against the pre-task-1.1 baseline (git show cf55d691^): all
four blocks' source lists, c_args, and env are faithfully reproduced,
only paths and the suite tag changed.

0 failures). controller suite unchanged: 1199 Tests 0 Failures 0 Ignored.

on controller_test.c) carrying their extern/RUN_TEST entries, and
register the new harness_unit_test executable + suite in
src/harness/meson.build with an explicit build-order dependency on
xce_test (two of its tests spawn that binary over a pty).

Finish clearing the controller side: remove test_test_cli.c/
test_xcetest_process_entry.c from controller_unit_test_src and their
extern/RUN_TEST entries from controller_test.c, and remove the
temporary xce_test_controller_link symlink bridge task 1.1 added (no
longer needed now that both binaries build as siblings under harness/).

Verified: harness suite 132 Tests 0 Failures 0 Ignored; controller suite

feat(xce-harness-component): relocate xce_test into standalone harness component
Move xce_test's 15 production sources + headers from src/controller/testsuite/
into a new src/harness/ component with its own meson.build, and strip every
now-dangling controller-side reference (11 controller_unit_test_src entries,
4 standalone test-binary blocks, 11 controller_test.c extern/RUN_TEST lines)
so the controller build is never left broken.

Fixes a broken relative-symlink bridge (xce_test_controller_link) added to
keep two controller-embedded tests (test_test_cli.c, test_xcetest_process_entry.c)
finding the relocated xce_test binary until task 2.1 moves them too.

Discovered and documented in design.md: four controller-domain regression
tests call functions directly from four of xce_test's own files, requiring
controller_unit_test to permanently recompile them from src/harness/ — a
real dependency neither the original discovery nor design audit caught.

controller_unit_test: 1228 Tests 0 Failures 0 Ignored (verified via the

notes, with hand-written per-flag lines removed as a duplicate source of
truth. Add missing purpose descriptions, examples, and confirmation-gate
related notes across ~20 commands; fix bug-1711's "matchs" grammar
(Req 11.2); confirm join's corrected maxmem default (bug-1557, Req 12.2)
and the --json flag (Req 5.4) now render correctly end-to-end.

feat(xce-test-cli-ux): add JSON output mode to the listing commands
Bring workerlist/joblist/reslist onto the shared flagspec_t library with an
identically-spelled --json flag, wired to the task-2.2 JSON list formatter
via a new pure field-mapping module (listrow_json.c/.h). Default table
output is unchanged; JSON rows carry raw numeric values (flags, timestamps,
memory sizes) rather than their humanized display strings, per Requirement
5.1's "same fields" contract.

feat(xce-test-cli-ux): wire confirmation gate to the five destructive commands
Gates jobkill and shutdown unconditionally, qctrl only when action is
QUEUE_CLOSE/QUEUE_INACTIVE (not ACTIVE/OPEN), hostctrl only when
HOST_CLOSE (not OPEN), and upgradeconfig unconditionally -- exactly
Requirement 9.5's enumeration, with jstart/jfinish/jfail (worker
context) correctly untouched. Each gains a -y/--yes bypass flag via
flagspec_t; cmd_set gains -y/+y calling confirm_set_skip(). A decline
maps to a plain `return 0` (success-coded, distinct from a negative
failure return) per confirm.h's own documented contract -- this means
a declined destructive command inside a source'd file under `set -e`
won't trip abort-on-failure, a real but narrow interaction only
reachable when a human is actively declining; left for task 4.3 to
test explicitly. 1321/1321 across the full controller suite (+3),
0 regressions.

feat(xce-test-cli-ux): wrap every blocking RPC with the interrupt adapter
Routes all 26 blocking xcecli_* call sites across ~24 commands through
xcetest_run_interruptible(), wires xcetest_set_active_connection() at
execute_line()'s dispatch point (active_ctx->ctx, read fresh per
command), and fixes main()'s REPL loop to distinguish a real EOF from
an EINTR-interrupted readline() so Ctrl-C at an empty prompt discards
the line instead of exiting the session.

Live-discovered and fixed bug-1794: fill_job_alloc() never initializes
xce_job_alloc_t's nres_shared/allocs_shared fields -- harmless as stack
garbage before this task, genuine heap garbage once moved into a
heap-allocated ctx block (a necessary consequence of the adapter's
heap-only precondition). Fixed by switching all ~26 call-context
allocations from malloc to calloc uniformly. Also fixed an argv-aliasing
hazard: cmd_hello/cmd_jobckpt's -m values aliased optarg, which
execute_line() frees immediately after return including on the
abandoned path -- now strdup'd into the heap block.

Also closed a safety-critical gap this task's own design introduced
(bug-1795): before this task the REPL was fully synchronous, so
leave_ctx() (called by up/quit) could never run while an RPC was
outstanding. An abandoned worker can now persist past command
completion, so leave_ctx() tearing down the connection could
use-after-free it. Fixed via xcetest_wait_connection_idle(), which
blocks on the same per-connection semaphore the adapter already
tracks, then releases it, proving no worker is active before teardown.
Proven with a deterministic white-box RED->GREEN test, since the race
itself is too timing-dependent for a black-box test to reliably force.

feat(xce-test-cli-ux): migrate all flag-accepting commands to flagspec
Migrates 17 commands (cmd_hello, cmd_jobinfo, cmd_jobrun, cmd_jobsub,
cmd_resval, cmd_jobkill, cmd_jobckpt, cmd_qctrl, cmd_hostctrl,
cmd_runtasks, cmd_setpend, cmd_jobstart, cmd_jobfinish, cmd_jobfail,
cmd_resupdate, cmd_walcompare, join_worker_parse_attrs) from raw
getopt()/hand-rolled parsing to the shared flagspec_t + getopt_long
mechanism, so every one now uniformly rejects an unrecognized or
malformed flag with a usage summary and, where a close match exists,
a suggestion. cmd_walcompare's hand-rolled parser needed a leading '+'
in its optstring to preserve its pre-migration flags-only-before-
positionals behavior. Also fixes bug-1704: cmd_qctrl's uninitialized
action variable, now sentineled and rejected when unset, mirroring
cmd_hostctrl's existing pattern -- this also makes the destructive-
command gate's -i/-c detection (task 3.3) safe to rely on. Every
existing short flag's letter, value format, and default is unchanged
for a valid invocation. 1357/1357 across the full controller suite
(+4), 0 regressions.

fix(xce-test-cli-ux): fix bug-1557's join maxmem default
cmd_join_worker's simulated-worker maxmem default was 64 bytes -- a
leftover from when the field was MB-scale, unfixed when maxmem became
bytes-canonical elsewhere. Now 64 * 1024 * 1024. Extracted the
argument-parsing/defaulting logic into join_worker_parse_attrs()
(join_worker_args.c), since it runs entirely before the function's
network call and is a genuine testable seam -- same precedent as
task 2.5's joblist_display.c. Verified live against a real deployed
cluster (workerlist reports MaxMem: 64.00 MB) plus a permanent 5-test
regression suite. maxswap/maxtmp have the identical stale-default bug
(logged as bug-1793) but are deliberately left unfixed here since
USAGE_JOIN_WORKER's help text currently documents their stale values
accurately -- fixing only the code would create a new docs mismatch;
a locked-in sibling-defaults test documents this for the follow-up.

fix(xce-test-cli-ux): fix bug-1711's display and text defects
Eight display/text defects in test.c: worker_status_str's "UNKOWN"
typo, cmd_runtasks's "sequentail" typo (display-only, verified inert
against the real launch_type consumer), cmd_reslist's right-justified
columns and unlabeled hex Flags (now matching workerlist/state_raw's
conventions), joblist's raw-epoch timestamps (now via a format_job_time
helper delegating to the same formatter ctrlstatus already uses) and
combined NTasks column split into MinTasks/MaxTasks, job_state_str's
missing raw-state fallback for ambiguous RUN+EXIT (mirroring
print_jobinfo's existing pattern), and getconf's no-op group/config
list stubs (now genuinely implemented from already-fetched data,
matching the three sibling print functions' convention).

worker_status_str/job_state_str/format_job_time are pure functions with
no networking/REPL/global-state dependency, extracted into a new
joblist_display.c/.h module with a permanent 20-test standalone suite --
following this codebase's own resval_typeresolve.c/misc.c precedent for
testing functions that would otherwise be stranded inside untестable
test.c. cmd_reslist/joblist_query/cmd_getconf's table-printing bodies
inline fetch+print and remain untestable without a live cluster.

feat(xce-test-cli-ux): add in-session source command with cycle detection
cmd_source reuses rcfile_load() unmodified for line execution, adding
an explicit missing-file check (bypassing rcfile_load's silent-missing
policy, which is correct for its one existing startup-rc-file caller
but wrong for an explicit user command) and a realpath()-canonicalized
in-flight path stack that rejects direct or transitive cycles instead
of hanging. Registered in all four command contexts. Translates
rcfile_load's raw positive "aborted" return to -1 so an enclosing
source line correctly sees a transitively-aborted nested source as
failure, not success (preprocess_and_run only treats negative returns
as failure). Proven via real fixture files driven through the black-box
pty harness: a genuine two-file mutual cycle, a missing path, and
ordered execution across a non-cyclic nested source. 1310/1310
controller suite passing (+3).

feat(xce-test-cli-ux): add command-name tab completion scoped to context
Registers libedit's GNU-readline-compatible rl_attempted_completion_function
under g_interactive only. The candidate generator reads active_ctx->commands[]
live on every call, so completion correctly tracks context switches rather
than freezing at registration time. Single/multi-match UI (auto-complete vs.
double-Tab candidate listing) is entirely libedit's stock behavior once given
a correct context-scoped generator. Proven via a black-box pty test verified
sound against a false-positive risk: xce_test has no fuzzy command-name
matching, so an uncompleted partial token cannot coincidentally trigger the
same effect a real completion would. Also fixes a harness bug (bug-1792):
disabling kernel ECHO for output capture was silently suppressing libedit's
own completion feedback too; added clitest_spawn_ex() with disable_echo as
an explicit parameter, clitest_spawn() unchanged for existing callers.
1307/1307 controller suite passing (+1), re-verified 8/8 for flakiness.

feat(xce-test-cli-ux): build JSON list-output helper library
listfmt_json_begin/new_row/add_string/add_number/finish wrap cJSON
(already linked via struct2json_dep) into a minimal array/object
lifecycle library with no generic "record" abstraction -- each command's
own row struct maps its fields directly when wired in later (task 3.4).

feat(xce-test-cli-ux): build destructive-command confirmation gate
confirm_destructive() prompts on stderr and blocking-reads a y/n answer
via a single, non-looping fgets() call (not libedit) -- the mechanism
that makes a real Ctrl-C during the prompt return EINTR and be treated
as a decline (Requirement 9.9), same as an explicit "n" or EOF.
confirm_set_skip()/confirm_is_skip_set() add a session-scoped toggle
mirroring cmd_set's existing -e/+e style. Auto-skips when input is not
interactive, via a new xcetest_is_interactive() accessor over the
existing g_interactive global. Destructive-command enumeration and
per-command wiring (Requirement 9.5) is task 3.3, not this task.
