Task 4.4: the --logfile path (or the default, now SCHED_DEFAULT_LOG_PATH)
reaches the sim driver as an owned copy so the trace file checks can
reject the scheduler log.

Task 4.3: trace on all|job SEL... [level] [lines N] [file PATH], off and
status, parsed from the raw line; invalid arguments are named and leave
the settings unchanged; refcounted next/current settings; status shows
the settings in effect or pending, whole arrays as <base>[*], and stored
trace memory against its bound.

Task 4.2: a new trace replaces a job's earlier one; above 64 MiB the
oldest traces are evicted (never the newest) and marked discarded until
a newer capture; info trace renders a job's or an array's stored traces
in the current units mode, or reports discarded / no trace with the
job's state / unknown job.

Task 4.1: hierarchy, summary-level position summaries, truncation marker
with the fixed totals block, 50-host outcome cap with aggregates and
separate limit charges, no-decision and reconstructed records, amounts
in the REPL units mode, identical bytes to one or two sinks.

Task 3.4: the runner records no-plan reasons, the cluster-wide check,
plans (tried, discarded, not tried) and their ends, positions, claimed
skips and per-host candidate verdicts, rollbacks, commit or finalize
failure, and search end. A declined or generator-failed requirement now
counts once as 'no plan generated'. Runner results are unchanged.
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
Task 3.3: the pre-filter records selection mismatches and internal
errors as host verdicts, a scan stopped by an error marks the position
as a scan error, and unsatisfy_() hands every checked row to the current
record. Iterator and check results are unchanged.
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
Task 3.2: single requirements, top-level compounds, alternatives and
members push their path level and record one begin and one end; member
failures record the members not tried, merge failures and skipped
alternatives are separate entries, the chosen alternative or all-failed
is recorded, and each compound attempt's reasons are captured before the
job's stored reason is replaced. Scheduling results are unchanged.

Task 3.1: when the sim publishes trace settings, sched_allocator() counts
job positions, starts a record for wanted jobs with their selection and
cluster-wide limits, pushes no-decision kinds as trace-only decisions,
and attaches the captured outcome to built decisions; every handoff
clears core->trace_rec. Live (trace_ctl NULL) is unchanged.
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
Task 2.4: outcome capture moves to sched_trace_outcome.c and the
position/host/summary/rollback half of the model to sched_trace_scan.c;
shared helpers go behind sched_trace_internal.h (sti_ prefix). Code is
moved unchanged; every target that compiles the trace sources gets all
four, and the core isolation scan covers the new files.

Task 2.3: dispatch rows with limit charges listed separately and
resolved through the job's matched limits (raw-number fallback), pend
reason set deep-copied, 50 hosts in detail with the rest aggregated,
and RECONSTRUCTED records holding the dispatch outcome.
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
Task 2.2: each checked row carries name, flags, value type, total,
in-use, reserved, requested and met (same comparison as unsatisfy_());
limit rows resolve through the scope's matched limits and never count as
shortfalls; the cluster-wide check keeps every row, a host only unmet
rows, which set its shortfall/limit verdict.
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
Task 2.1: policy, queue and priority/queue-time ordering keys, each
matched cluster-wide limit as (name, scope), and per-code attempt
failure reasons with the hosts and resources they name, all copied into
the record arena.

Task 1.8: the core gains trace_ctl/trace_rec (NULL unless the sim REPL
sets them) and SCHED_TRACE evaluates its call only while a record is
being built.

Task 1.7: xce_decision_t gains a trace pointer (NULL from every existing
constructor) and XCE_DECISION_TRACE with make_trace_decision(); the live
driver skips trace-only decisions and frees any attached trace.

Task 1.6: the 27 tests that #include a hooked scheduler source now also
include sched_trace.c and sched_trace_capture.c.
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
Task 1.5: per-requirement plan counts and search-end statements,
decision-wide counters exact past truncation, summary-level position
tallies (per verdict kind and per limit), merged rollback entries.
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
Task 1.4: requirement path push/pop with balanced begin/end entries
carrying the full nesting path, one entry per traced event kind, and a
line budget that stops storing at the bound and counts omitted lines.
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
Task 1.3: trace types and constants, per-record arena, job selection
matching, no-decision record finishing; empty capture module; both
sources scanned by the core isolation test with a no-stdio check.
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
Task 1.2: translate_units_mode, repl_format_numeric_resource_value,
repl_format_consumable_value_and_used and repl_current_units_mode move
unchanged from repl_info.c and are declared in repl_internal.h so the
trace renderer can reuse them.

Task 1.1: scripted REPL session over a contention replay (license, cluster
and host limits, parallel and alternative jobs); transcript, recordings and
--sim-verify result committed as fixtures and compared byte for byte.

18 sub-tasks in 6 groups (libxce primitives + regression script
skeleton; controller; scheduler/worker/harness; xceadmin; integration;
docs). Each C task adds its failing regression-script case before the
change. Requirements, design and tasks approved.

Iterated design review until clean (GO):
- Controller main() calls mylog_fini() before every early return, so
log lines written by tlog's background thread survive the exit.
- cluster_init_phase1() keeps its candidates_count > 0 guard around the
new xce_peers_find_identity() call (standalone stays my_priority 0).
- xceadmin adds the "(from $VAR)" source note only to network errors,
not to local cluster-bin file errors (OSError with filename set).
- Regression script: scratch --workdir/--certdir/--logfile per daemon,
refuses to run if a local cluster is up (port 9990, worker socket),
--sim case asserts the sim branch ran, 2.3 patches follow_redirects,
2.8 malformed-entry cases use a readable cluster-bin file, wrapper
test expects PEERS_STR form.
- Two existing scripts that start xce_scheduler without --peers will
unset XCE_CONTROLLER_PEERS; --interactive wording corrected.

Design review (NO-GO -> GO) and iterated requirements review until clean:
- Controller refuses to start (non-zero exit, stderr, before any network
I/O) when an env-supplied XCE_CONTROLLER_PEERS lacks its own name (1.6);
new libxce xce_peers_find_identity() replaces both identity loops in
controller/cluster.c so the check and my_priority/listen port agree.
- deploy-ha.sh's generated scripts/xceadmin wrapper exports
XCE_CONTROLLER_PEERS so an ambient value cannot redirect it (Req 4).
- Opt-out is unsetting/emptying the variable (1.7); "No --peers" log
lines say it was unset or empty (1.8); docs cover sudo/systemd not
inheriting it (3.1).
- Requirement 1 defines explicit candidate list / resolution point /
own name so harness (set masters) is covered precisely; error messages
name the value's source incl. validation failures (1.4).
- xceadmin: name= stripping and a clean malformed-entry error apply to
every --controller source; errors name the env var source (2.2, 2.8).
- Test plan fixed against real code (stderr vs stdout, log texts,
xcecd_virtual, --norc, free ports, failover order test).

src/docs/xce.md gains a 'Job arrays' section: name[1-N] and name[1],
numbering from 1, the API-server limit (default 1000, at most 32767),
<array-id>[k] and <array-id>[a-b] selection (with the peek/restart
caveat), XCE_JOBINDEX, the harness jobsub -a N / $jobid[k], and every
LSF array feature this release does not support. The superseded
statements in job-array-single-wal-record and xce-test-e2e-primitives
are annotated (history kept), the controller-job-cleanup and
job-dependency briefs describe 1-based numbering, and the roadmap gains
an entry.

The HA array soak checks small-array elements 1..N, large-array first,
middle and last as 1, N/2 and N, status/cancel/completion on 2, N/2+1
and N-1, and the chaos-retry round over seq 1 N; the multihost
verification drives element [1]. Comments now say that after jobsub -a N
the success line and $jobid name the array identity. Historical
live-run quotes that show [0] are kept and annotated as predating the
change.
