New briefs: host-failure-job-recovery (jobs on a lost host are requeued or
end EXIT after a grace period; stale copies fenced on rejoin; manual
requeue), service-supervision (profile kind service: restart policy and
liveness/readiness probes run by each replica's own worker, in-place
restart), service-replica-set (controller-held service object owning
independent replica jobs; event-driven replacement, scaling and rolling
update; no head agent, no promotion), service-endpoint (per-replica ports,
endpoints of ready replicas), job-resize (backlog, elastic jobs).
application-profile brief gains the service section; roadmap lists the new
specs, the existing-spec updates and the backlog item.

New steering job-config-layering.md: queue = scheduling policy, application
profile = what the application needs and how it runs (resreq, task range,
execution settings, pre/post-exec, limits), project = resource ownership.
Only two interactions: the job overrides a profile attribute marked
default (fixed: not at all; select: only ANDed terms), and queue ceilings
or project quotas check effective values (reject if never satisfiable,
pend if full now). Replaces the simplified job > app > queue rules.
Queue pre_exec/post_exec are deprecated with queue res_req: the profile's
pre/post-exec fills the worker's existing outer layer, the job's own stays
the inner layer, allowed or forbidden by the profile.
job-config-merge and application-profile briefs and the roadmap follow;
CLAUDE.md lists the new steering file.

New briefs: job-config-merge (one live merge of job, application profile,
queue policy and project into effective values; simplified rules: job
overrides profile, select ANDed, queue hard/task limits reject; queue is
policy only, res_req deprecated), project-config (project quotas v1) and
project-guarantee (backlog).
application-profile: the profile carries the job's resreq (incl. span) and
task limits; "frozen at submit" replaced by the live merge.
parjob-placement: span constraints live in the fixed-N planner and the
range search bisects over the planner's allowed counts; LSF 10.1 block,
ptile, stripe and HOSTLIMIT_PER_JOB findings recorded.
Roadmap: new specs, existing-spec updates, lsf-config-migration backlog.

New specs from /kiro-discovery (2026-09-28/29), added to roadmap.md:
- job-status-detail-display: show pending reasons and reserved-vs-used
resources in REST and xcecli. Requirements generated (7 requirements).
- scheduler-alter-pend-reasons: keep a pending reason for every alternative
resreq (per-alternative JobPendReason) and fix the obj->reason leak.
- controller-job-cleanup: primary-only sweep that removes finished jobs past
a configurable retention, via a replicated WAL removal fact.
- application-profile: admin-defined application profiles (execution mode,
launch type, env, resource defaults) chosen per job, with app:use/app:view
RBAC. Queues and profiles stay orthogonal.
- job-sandbox-execution / job-sandbox-multinode: run jobs in a systemd
DynamicUser sandbox behind a pluggable execution backend.
- rbac-persistence: make RBAC changes made through the API survive an
apiserver restart (closes the security.md gap).
roadmap.md also records the scheduler-sim-diagnostics info job update and a
security item: remote-task units appear to run as root (found by code
reading).
