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.

Task 3.1 of .kiro/specs/xce-test-cli-ux/tasks.md.
Requirements: 2.1, 2.2, 2.3, 2.4, 6.1, 6.2, 6.3, 6.4, 10.1, 10.2, 10.3

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.
1353/1353 across the full controller suite (+5), 0 regressions.

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.
1348/1348 across the full controller suite (+20), 0 regressions.

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 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.
Proven with a real fork+SIGINT test. 1297/1297 controller suite
passing (+7).

feat(xce-test-cli-ux): add process-level help/version discovery
argp already provided --help/-?/--version with exit-without-REPL
behavior, but had no -h alias (its default short help flag is -? per
GNU argp convention) despite Requirement 4.1 naming -h explicitly.
Added a hidden -h option triggering the same help path, and extended
the doc string to describe the in-session help command. Proven against
the real compiled binary via subprocess tests, not just argp's own
in-process behavior. 1289/1289 controller suite passing (+4).

feat(xce-test-cli-ux): fix SIGINT install to guarantee EINTR, add accessor
Replaces the bare signal(SIGINT, sigbreak) install with sigaction() and
SA_RESTART cleared, so a blocking read reliably returns EINTR instead of
being silently restarted by glibc's BSD signal() semantics. Adds
xcetest_interrupted() as a read-only accessor over the existing break_out
flag for the interruptible-call adapter (tasks 1.4/1.5) to consume.
Proven by a real fork+SIGINT+blocked-read test that first demonstrates
the old bug, then the fix. 1280/1280 controller suite passing (+2).

fix(bug-1735): job memory/CPU usage always read 0 in scheduler replay
Two independent gaps in misc.c/job.c, both silently zeroing every real
job's resource-usage data:

- update_host_runusage() matched worker rusage report resnames
  "cputime"/"mem", but the real worker's collector
  (collect_job_rusages(), xcecd_cgroups.c) sends "cpu_time_sec"/
  "memory_rss" -- the two never matched, so cpu_time/mem_usage stayed
  at their calloc()'d zero for every non-simulated job. Aligned both
  sides, including xce_test's own simulated-worker fixture.
- update_job_rusages() had a standing FIXME: xce_job_runusage_t's
  job-level max_mem/avg_mem/used_mem/cpu_time were never derived from
  the per-host host_runusage[] entries. Added aggregate_job_runusage()
  (sum/max/avg across hosts) and wired it in right after the per-host
  update.

Added test_host_runusage.c (standalone unit test, mirrors
resval_typeresolve_unit_test's isolation pattern) plus the
controller_unit_test stub aggregate_job_runusage() needs since that
target excludes the real misc.c.

feat(xce-test-rc-file): task 2.2 wire rc-file loading into xce_test startup
Adds the integration call site in main(), between g_continue_on_error's
computation and the read loop: unless --norc is given, resolve the rc-file
path and load it through preprocess_and_run (the same command-execution
path used for typed/piped input). A NULL path (no XDG/HOME) or missing
file falls through silently to the read loop. A failing rc-file command
under scripted/piped abort-on-first-failure mode short-circuits straight
to the existing g_session_failed exit-code convention, never entering the
read loop -- so a piped script's own commands never run after an rc-file
failure. Verified end-to-end against the built binary, including a real
pty for the interactive path, in both the failure and success cases.

Adds struct arguments.norc, a --norc argp option, OPT_NORC (matching

test.c. Parsing/recording only -- no wiring into main()'s control flow
or rcfile.c yet (task 2.2).

fix(worker): job ids print human-readable format via fmt_jobid() (bug-1588)
Extends bug-1588's job.c fix to the remaining raw-%lu jobid logging sites:
8 worker daemon files (xcecd_worker.c, controller_connector.c, uv_ipc.c,
xcecd_worker_utils.c, xcecd_dbus_manager.c, xcecd.c, main.c, xcecd_cgroups.c)
and src/controller/testsuite/test.c (xce_test, heavily used for controller
testing). 99 call sites converted to fmt_jobid()+%s, matching the existing
convention. Non-jobid %lu values (lsn, client id, byte offset) and raw-numeric
identifier/path construction (checkpoint dir, systemd unit name, XCE_JOBID
env var) are deliberately left untouched.

Verified via /xce-build worker and controller (asan, --incremental): both
compile clean with zero warnings tied to the change; worker suite 4/4 OK,
controller suite 4/5 OK (the one failure is the pre-existing bug-1561
overlayfs fdatasync flake, unrelated to this change).

feat(dirty-content-fingerprint): controller/scheduler show fingerprint in --version
controller/main.c and scheduler/src/main.c now compose argp_program_version
via a genuinely separate buffer/call to xce_compose_version_ex() (reading
STR(VERSION_DIRTY_FINGERPRINT), matching the existing commit_id/build_time
macro pattern). The startup-log composition call site -- same function,
same arguments, same buffer -- is left completely unchanged in both files.
controller/testsuite/test.c (xce_test, confirmed to have no startup log)
gets a direct in-place swap. All three files carry explicit comments
marking the --version/startup-log divergence as deliberate.

Verified independently by review with real builds and live daemon starts:
--version shows <commit>-<fingerprint> for all three binaries, matching
compile_commands.json; live startup logs for both daemons show the
unchanged old <commit>-dirty format with the fingerprint never present.

feat(build-time-versioning): controller/scheduler --version and startup log
Migrates argp_program_version in controller/main.c, scheduler/main.c,
and xce_test's test.c from the compile-time MK_VERSION/STR construction
to xce_compose_version(), computed into a static buffer and assigned
before argp_parse() runs (argp_program_version is a file-scope pointer,
not a constant expression it can be initialized from at compile time).

Each daemon's startup log now carries the identical version string
(never recomputed) on its first INFO line -- scheduler's BOTH
mutually-exclusive branches (--peers and no-peers), not just the one
literally named in the task text, since "when the daemon starts" is
unconditional.

Live-verified: --version and startup-log output are byte-identical for
both daemons across all branches. No remaining MK_VERSION callers
repo-wide.

Task 3.2/13 of build-time-versioning.

feat(resource-value-verification): per-name accept/reject verification in resupdate (task 2.2)
cmd_resupdate() now issues a follow-up xcecli_resval() query per submitted
(resource, worker) pair after the update RPC, since update_resval_list()'s
reply can't carry per-item status. Reports accepted/rejected per name, with
a bounded retry (5x100ms) against propagation races.

Live-confirmed: `resupdate -n mem -v 5 -n not-a-real-resource -v 1` reports
mem accepted and not-a-real-resource rejected in the same invocation.

feat(resource-value-verification): wire resolver into resupdate, add -t flag (task 2.1)
set_resval() now delegates type resolution to resval_typeresolve.c; unknown
resource names default to numeric, overridable via a new -t <numeric|string>
flag. cmd_resupdate()'s getopt loop defers per-pair finalization so a
trailing -t still applies to its pair, while preserving the exact original
duplicate-value rejection behavior (round-2 fix after review caught a
last-write-wins regression in that refactor).

Live-confirmed: resupdate -n r15m -v 1.5 (previously silently dropped) now
succeeds and is visible via resval.

fix(controller): close 6 data-safety races + apply-pump O(N^2) regression + boot TOCTOU
Bundles the fixes validated this session across ha.c/persist.c/worker.c:

- raft-apply-decoupling Task 7.4: apply-pump O(N^2) throughput regression
  fixed via a segment-read cache.
- bug-1416: boot-time TOCTOU race in persist_verify_apply_correctness()
  closed with a recovery-complete gate that closes at process-lifecycle
  start, not function entry.
- bug-451: HOOK_DETAIL_JOB_RUSAGE_UPDATE now has its own persist hook arm
  instead of silently falling through the default job-state case.
- bug-1426: trim_wal_segments() also caps its trim floor at the local
  apply pump's own progress, not just remote standby-acked positions.
- bug-1427: persist_verify_apply_correctness() extended with a worker-count
  check mirroring the existing job-count check (count_jobmgr_entries and
  count_workermgr_entries now share one count_manager_entries(var) helper).
- bug-1428: persist_register_pending_apply's critical section widened to
  close the actual race instead of patching a symptom.
- bug-1472 (remainder): WORKER_DEAD replay in worker_from_capnp() now
  applies mark_worker_unavail()'s mutations via a shared
  apply_worker_dead_mutation() helper instead of duplicating them.
- bug-1474 (angle-a): on_standby_connected's stale-duplicate detection
  fixed for promoted vote endpoints via a shared votes_idx_for_peer()
  index-scale converter.

Each fix independently verified via TDD (RED before fix, GREEN after).
Full ASAN rebuild + controller_unit_test: 1101 tests, 0 failures. Live
single-node HA deployment validated Task 7.4 and bug-1416 across 5
restart/recovery cycles (45/45 job submissions, zero APPLY_DIVERGENT

refactor(controller,xceadmin): drop generic Resource.unit, hardcode bytes for maxmem
Simplification per review feedback on e3b3ffa: a generic schema-driven
unit field touched the capnp wire schema (2 structs), C structs
(xce_resource_t/xce_resval_t), resobj.c's deep-copy/destroy, opget.c's
reply-build lookup, resources.yaml/resources.schema.json, and mapping.py
-- real cross-cutting cost for a mechanism only one resource (maxmem)
actually needs today.

Reverted all of that. The controller CLI (test.c) now just knows
"maxmem" is bytes-valued via a small explicit is_bytes_valued_resource()
name list, and adaptively picks the best-fit human unit at display time
(format_bytes_human, unchanged) -- same observable behavior (resval/
workerlist render maxmem as e.g. "30.90 GB"), zero wire schema surface.
Regenerated the xceadmin golden fixture back to its pre-unit-field size
(5304 bytes, exactly matching the size right after the mxj-only fix,
confirming a clean, complete removal).

Verified: 1095/1095 controller_unit_test (3 runs; one hit the
pre-existing flaky segfault already logged as bug-1553, unrelated),
228/228 xceadmin pytest, clean rebuild of lib/controller/xceadmin/xce_test.

fix(controller,xceadmin): fix zero-slot scheduling block, misleading resval logs, byte-unit display
Three bugs found while diagnosing a live controller log, all in the
worker resource-value path:

1. Every host relying on the documented hosts.yaml auto-detect default
   (no max_slot, meaning "use CPU count") got 0 scheduling slots,
   permanently blocking the scheduler from placing jobs on it. mxj is
   UInt32 on the wire and can't carry the schema's -1 sentinel; mapping.py
   worked around this by leaving it unset, which defaults to 0 -- and 0 is
   never < 0, so apply_join_state()'s auto-detect fallback never fired.
   Fixed by encoding the sentinel as 0xFFFFFFFF, which the controller's
   `int mxj` field reinterprets back to -1 via its existing implicit
   uint32_t->int conversion. No C-side or wire schema change needed for
   this part; the fallback itself was already correct but had zero test
   coverage for a negative mxj, now added.

2. update_resvals()/update_resval_list() logged the failure reason via
   PERROR, which reads process-global errno -- but update_resval()'s
   failure paths return raw negative codes directly and never touch
   errno, so the controller log filled with misleading "update_resval:
   Success" / "update_resval: Resource temporarily unavailable" lines
   instead of the real reason. Fixed to decode the actual rc via
   xce_strerror_r and name the failing resource.

3. maxmem is canonically stored/wired as raw bytes but had no unit
   metadata, so resval/workerlist printed it as a bare number that read
   as garbage (e.g. workerlist's fixed-width columns visually smeared a
   multi-GB byte count across the MaxCPU/MaxMem headers). Added an
   optional `unit` field to the Resource/ResourceVal capnp structs (and
   xce_resource_t/xce_resval_t/resources.yaml) so resval and workerlist
   can render a human-readable value (e.g. "30.90 GB") while the stored
   value stays raw bytes -- display-only, every other resource unaffected.

Regenerated the xceadmin golden fixture (fixtures/full/expected.bin)
twice: once for the mxj sentinel encoding change, once for the new
Resource.unit field growing every resource's wire size by one pointer
slot. Both diffs verified byte-for-byte isolated to exactly the expected
change before regenerating.

Verified: 1095/1095 controller_unit_test (stable across repeated runs),
229/229 xceadmin pytest, clean rebuild of lib/controller/xceadmin/xce_test.
Two related findings logged to .wolf/buglog.json but deliberately not
fixed here (out of scope per discussion): a pre-existing flaky segfault
in the combined controller_unit_test binary, and maxswap/maxtmp being
hardcoded stub values on the worker side.

feat(scheduler-core): implement REPL execution control (task 12.1)
Adds the interactive simulation REPL's execution-control slice (Req 5
AC 22): a single-threaded input loop (readline-based) supporting
step [N], continue, quit, and help, pausing before the first replay
event and blocking the driver loop while active.

Review round 1 raised two findings, both resolved here:

- GNU readline (GPL) was linked directly into xce_scheduler, a shipped
  production daemon. Switched the whole project to libedit (BSD) for
  line editing -- scheduler and controller (xce_test) both now use
  editline/readline.h, API-compatible (readline()/add_history()).

- Getting a clean regression run after the libedit swap required a
  full clean rebuild, which exposed a genuine pre-existing SIGSEGV
  (bug-1504): SnapshotData.internalState was a capnp Data field, and
  this codebase's capnpc-c backend silently no-ops Data-field
  encoding without zero-initializing the caller's stack struct,
  leaving an uninitialized capn_ptr written onto the wire. Fixed by
  switching internalState to List(UInt8) (with a new internalStateLen
  wire field), matching the working FetchFileReply.content/bytesRead
  precedent -- no hand-written accessor code needed.

A second, unrelated instance of the same bug class was found in the
controller's WAL-catchup path (WalCatchupEntry.payload) and
deliberately left unfixed as bug-1505, out of scheduler-core's
boundary; needs its own project-wide Data-field audit.

Scheduler suite: 34/34 clean. RED-phase reproduction recorded in
tasks.md (repl_should_pause() step-budget check disabled -> 2/4
tests fail as expected -> reverted -> 34/34 green).

(run-ha-soak.sh --config-upgrade) required by Requirements 4.1, 4.3, 6.1,
6.4. This needed genuinely new client-side infrastructure: a hand-rolled
capnp send path for OP_upgradeConfig (the auto-generated encoder is a
no-op for its Data fields, worked around the same way
xce_replconfigpush_req_raw already does), plus cmd_hostctrl/cmd_upgradeconfig
CLI commands.

Building and running this live surfaced two real production bugs, both
fixed here:

- bug-1468: an unrelated prior commit inverted OPCode_upgradeConfig's
  primary/standby dispatch guard in cluster.c, making config upgrades
  unreachable from any network client.
- bug-1469: apply_committed_entry's WAL_CONFIG_MARKER case never called
  config_activate_committed(), so the node that originates a config
  upgrade never refreshed its own in-memory state as part of committing
  it. Killing that node before some later, unrelated event happened to
  refresh it left its checkpoint permanently stale -- the first live,
  empirical reproduction of bug-857's originally hypothesized failure
  mode. Fixed by activating before the marker-triggered checkpoint write,
  since checkpoint content is built from live runtime tables that only
  reflect the reload after activation runs.

A separate, narrower checkpoint divergence (bug-1471, not config-related)
remains open and still blocks a clean soak PASS -- task 8.6 stays
in-progress until it's resolved.

1d09631df0 feat(config-upgrade-snapshot): add configcompare tool, extend snapverify (task 8.4)
Build configcompare_paths(), an offline sibling to snapdiff/walcompare that
recomputes each member's active-config sha256 fresh from its own on-disk
workdir/name/conf bytes and reports identical vs. divergent (Req 4.2).
Wire it as a cmd_configcompare CLI subcommand in test.c, matching its
siblings, after review caught it shipped as an unreachable library function
in round 1.

Extend snapverify to match the current on-disk checkpoint format: bump
SNAP_FORMAT_VERSION to 2, replace the stale raw queue-frame decode with the
capnp length-prefixed walk, add host-frame and config-bytes-section
structural walks, and decode (not just presence-check) the header's
cfgref tag/sha. Without this fix snapverify rejected every checkpoint
written by the current codebase.

e53c086ec5 fix(schema): rename struct Data -> XceData to unshadow capnp builtin blob type
controller.capnp declared `struct Data $C.mapname("xce_data_t")` (an
OPCode_get query-result tagged union) at file scope, which shadows
Cap'n Proto's builtin Data blob type for every later `: Data` field in
the same file. This silently miscompiled 7 fields across 6 structs as
a struct-pointer type instead of a raw byte blob: UpgradeConfigRequest
.sha256/.bytes, ReplConfigReply.sha256/.bytes, ReplConfigPushRequest
.sha256/.bytes, ReplEnvelope.payload, SnapshotTransfer's chunk
payload, WalCatchupEntry.payload/.batchPayloads, and CtrlHelloRequest
.key. Production C code had already routed around it for years via
hand-rolled raw capn_ptr manipulation (see request.c's own comments);
nothing before now needed the generated codec/accessors to actually
work for these fields.

Renamed the local struct to XceData (capnp-level name only; the
$C.mapname("xce_data_t") C typedef is unchanged) and explicitly
repointed getdata/pushmsg at XceData by name, since those two fields
correctly want the local tagged union. Updated every derived
generated-identifier reference across 19 hand-written files spanning
controller, lib, scheduler, and the Go apiserver/xcecli CGo bindings.
Fixed 5 call sites in lib/request.c that had been typed against the
old workaround alias but now legitimately receive the correct
capn_data type (a pure type-name swap -- Data_ptr/XceData_ptr and
capn_data share the identical {capn_ptr p} layout).

Verified via full rebuild+test: lib (1/1), controller (3/3, incl. the
job-array push regression tests), scheduler (15/15), Go apiserver +
xcecli (all packages green), and a direct pycapnp round-trip proving
UpgradeConfigRequest.sha256/.bytes now encode/decode correctly.

Bug: bug-1461 (.wolf/buglog.json). Unblocks admin-config-tool task 3.3.

f28ce57993 fix(raft-apply-decoupling): bug-1419 layer 3 — close cross-primary client-retry dedup gap
jobid_range_exists() (c->jobmgr) and the in-flight registry (job.c,
per-process, only populated by this node's own handle_jobsubmit calls)
both miss a real cross-node case: a client's XCECLI_FAILOVER_CALL retry
resends the same client-generated jobid after a connection drop, and the
resend lands on a newly elected primary that never processed the original
request. If the original was already committed before the old primary
died, the new primary's own local WAL already holds it (Raft Leader
Completeness) but jobmgr hasn't applied it yet — both existing guards see
nothing, so the resend appends a second, genuinely committed WAL_JOB_SUBMIT
entry for the same jobid. A live chaotic soak reproduced this exactly
(waldump: two committed entries, same term, matching apiserverId/timestamp/
sequence, one second apart) — apply's own idempotent dedup keeps jobmgr
correct, but replay's raw WAL_JOB_SUBMIT count no longer matches jobmgr's
growth, firing a false APPLY_DIVERGENT fence and deadlocking promotion.

Fix: apply_committed_entry()'s WAL_JOB_SUBMIT case now claims the jobid in
job.c's in-flight registry (new job_wal_commit_claim/release, wrapping the
existing inflight_range_try_add/remove) for the duration of dispatch,
regardless of whether this node originated the submission or is applying a
replicated/replayed entry. A resend landing mid-dispatch on any node now
sees the same -EEXIST rejection self-originated in-flight submits already
get. Release only fires when the claim call added the entry, so a
self-originated submission's own claim/release lifecycle (unchanged) is
never double-released or stolen.

Also fixes 4 pre-existing tests that broke under the earlier checkpoint_lsn
fix (0eb1054) and were missed in that commit's regression sweep: cluster-
less fixtures where last_applied_lsn never advances now correctly get
checkpoint_lsn=0 unless the test simulates apply catch-up, matching the
new (correct) semantics. One assertion in
test_checkpoint_tail_with_no_snapshot_is_apply_clean compared Phase 1's
checkpoint_lsn against Phase 2's independently-reconstructed physical WAL
tip — that equality only held under the pre-fix current_lsn-tracking
behavior and is removed, not patched around.

Also hardens run-ha-soak.sh's start_node() with setsid+nohup: a forked/
background test-harness invocation whose session tears down mid-run was
silently killing every controller process via SIGHUP forwarding (observed
twice — deploy completes, ~1s of activity, then all 3 nodes die together
with no error logged).

1b6041acef fix(xce-test-ha): bug-1420 harness jobid collision + bug-1419 regression coverage
xce_test's cmd_jsub hardcoded idgen(&idctx, 0, 0, ...) (clusterId=apiserverId=0),
and run-ha-soak.sh's submit_jobs() spawns a fresh xce_test process per retry
attempt, resetting idgen's static sequence counter each time. Two unrelated
job submissions from separate process launches landing in the same
wall-clock second collided on an identical jobid, surfacing as a spurious
APPLY_DIVERGENT fence in chaotic soak that was initially misattributed to
bug-1419's controller-side dedup logic.

Confirmed not a production risk: apiserver's GenerateJobID holds one
process-lifetime idgen_ctx_t via sync.Once, and each deployed instance has
its own distinct apiserverId, so config.h's jobid bit layout already
partitions the production namespace. Fixed by folding getpid() into the
harness's apiserverId so cross-process collisions become structurally
impossible there too.

Also adds test_jobsubmit_resubmit_after_full_resolution_rejected_no_second_job
to test_commit_barrier_reply.c, proving the post-resolution dedup window
(retry arriving after commit+apply+reply+release) is airtight, complementing
the existing before-resolution test -- both known bug-1419 dedup windows are
now provably race-free, confirming those fixes were never the cause of this
soak failure.

a5e29a6ffa fix(raft-apply-decoupling): kill-mid-fact-stream soak + close bug-1416 boot-time TOCTOU (task 7.2)
Adds --factstream HA soak mode driving real jstart/jfinish/jfail worker-fact
traffic against a live 3-node cluster, killing the primary mid-stream and
asserting zero committed-state divergence and zero phantom fact reactions.

Building this scenario surfaced bug-1416: persist_recover()'s boot-time
apply-correctness verification can race the live apply pump and the standby
live-replication apply path, both of which mutate the same last_applied_lsn/
job-table state the verification re-reads live -- producing a false
APPLY_DIVERGENT that permanently fences an otherwise-healthy node. Fixed with
a new persist_t.recovery_complete gate that defers only the in-memory apply
(never the durability write or replication ACK) while a recovery pass is in
flight, closed from the earliest safe point in myapp_run() so an election-
retry candidate can't apply live traffic before persist_recover() ever runs.

Round-2 adversarial review independently verified the ACK/durability paths
stay ungated, reproduced the myapp.c fix as load-bearing via revert-and-
reproduce, and confirmed real-divergence detection still fires. Live 3-node
factstream soak: 2/2 rounds PASS, zero APPLY_DIVERGENT across 5 recover
calls. controller_unit_test: zero new failures across 23 groups.

9318f9977e fix: close bug-1401 ctrlstatus leak, bug-1400 jobsub leak; harden bug-1396 harness
bug-1401: xce_free_ctrlstatus(s) was defined as free_CtrlStatus(s), which
only frees the fields inside xce_ctrlstatus_t. The real client reply path
(decode_CtrlStatus_ptr) calloc's the struct itself, so every ctrlstatus call
leaked sizeof(xce_ctrlstatus_t) (120 bytes). Existing unit tests never caught
it because they built/freed the struct via the raw stack-decode + bare
free_CtrlStatus() helpers, never exercising the actual client macro. Fixed
by switching the macro to free_CtrlStatus_ptr(&(s)) and added a regression
test that exercises the real heap-decode path; RED confirmed the exact
120-byte/1-alloc LeakSanitizer signature before the fix.

bug-1400: the originally reported SEGV in cmd_jobsub on malformed positional
input is stale — NULLSTR guards added 2025-11-05 already reject it cleanly.
The real residual defect was submit.start_info leaking on all 4 early-return
validation paths; fixed by routing them through a shared `goto cleanup`
(matches the existing goto-clean idiom in queue_ctrl).

bug-1396 (job-count anomaly after cold-restart-all, not yet root-caused):
instrumented test-commit-durability.sh's assert_job_count() to dump the live
joblist and ACKED_FILE ledger on any count mismatch instead of only the
count, per the bug's own recorded next step.

Verified: controller ASAN build + full controller_unit_test green; lib
xcelib_test 285/285 green, 0 ASAN leaks.

5cb36794d2 fix(raft-drive-async): resolve snapshot chunk-drop (bug-1386) and chunk misordering (bug-1389)
ha_send_snapshot_to_standby ignored the network send's return value in its
chunk loop, silently truncating a transfer on a mid-stream error while still
logging "complete" (bug-1386). Fixing the silent drop exposed a second,
independent bug in the same pipeline: ha_handle_snapshot_chunk appended
received chunks in arrival order instead of at their wire-carried
chunk_offset, so out-of-order delivery across the vtask pool corrupted the
reassembled file even though every chunk's bytes were individually correct
(bug-1389). Fixed by checking every fallible call in the send loop and
switching the receiver to pwrite-at-offset with a count-based completion
tracker.

Adds snapverify/snapdiff xce_test commands (offline checkpoint-file
structural validator and byte-level comparator) used to diagnose bug-1389 and
kept as standing diagnostic tools for future snapshot-transfer triage.

g_drive_async_configpush_offload flipped back ON after both fixes, validated
via 6-round chaotic + 3/3 force-snapshot soak (raft-drive-async task 3.3).

Add ctrlstatus_fmt.h (ctrlstatus_format_time_ms): renders responder_time_ms as
local YYYY-MM-DD HH:MM:SS,mmm, byte-equivalent to the controller log prefix
(tlog/my_tlog_format) so a captured ctrlstatus lines up against ctrl-N.log.
cmd_ctrlstatus prints a responderTime line; TZ-pinned exact-string unit test.

4c5b27cb70 test(controller): merge host/port into a 'masters' list for failover in enter_ctx
The xce_test client config previously used separate 'host' and 'port' settings
and hard-coded nmasters=1, so it could only target a single controller and
could not exercise controller HA failover.

Merge them into a single 'masters' setting (comma-separated "name=host:port"
or "host:port" entries — the same syntax as the controller --peers flag) and
parse it in enter_ctx() with the shared libxce parser xce_parse_peers(), filling
config.nmasters / config.masters[] / config.master_ports[] (capped at
N_MAX_MASTERS). The test client now fails over across controller candidates
exactly like the worker/scheduler/apiserver.

The parsed list lives in a static xce_cluster_config_t so its hostname buffers
outlive enter_ctx() (xcecli_ctx_init stores the config pointer, it does not copy
masters[]). enter_ctx() now returns -EINVAL on an invalid/empty masters setting
(callers already check rc<0). Default masters='localhost:9990' preserves the
prior single-controller default. Builds clean; 'set' shows the masters setting.
