Add record_job_reconcile_pending_fact(cluster_t*, job_t*) to job.c:
eagerly applies apply_job_update_transition(job, JOB_STAT_PEND) (real,
live mutation, not a deferred peek -- matching dispatch_a_job_'s
established pattern, not record_job_finish_fact's), releases
job->job.allocs on an applied (non-no-op) transition, then durably
appends via the generic persist_submit_job_fact(WAL_JOB_UPDATE). Caller
holds job's lock throughout and is responsible for calling
persist_notify_job_updated_already_persisted() after unlocking -- this
function deliberately does not call it itself.
Closes bug-1631 at this new call site: a RUN job with a real allocation
reconciled to PEND (Requirement 4.6, worker reports it unrecognized)
would otherwise carry a stale allocation into its next dispatch attempt,
exactly the gap bug-1631 documented as dormant until something re-admits
an already-dispatched job to the scheduler's PEND pool -- this feature
is that path. dispatch_a_job_ itself is unchanged (still correct for a
job's first-ever dispatch, the only case reachable there).
3 tests: allocs release + eager-mutation-before-unlock proof, no-op on
already-pending, and the Requirement 4.4 terminal-state-preservation
proof (rejects overwriting JOB_STAT_DONE).

All 5 sub-tasks (1.1-1.5) done: wire protocol schema, worker reconciling
status type, worker test infra (pre-existing), wire codec helpers, and
xceadmin config-build wiring.

Add workerResyncWindowMs/workerResyncTimeoutMs to xce.schema.json
(minimum:0, matching the optional-scalar-field precedent -- these
aren't `required` with a floor like heartbeatInterval, so minimum:1
would be wrong) and to mapping.py's YAML->capnp field table. Regenerate
both golden config-build fixtures (task 1.1 grew ClusterConfig's wire
layout by 2 fields; full/expected.bin and minimal/expected.bin each
grew by exactly 8 bytes). full's fixture YAML now sets real values
(900000ms/15000ms); minimal deliberately left untouched (no xce.yaml)
per its own locked-down "hosts+queues only" boundary test -- its
expected.bin still regenerates to reflect the new default-0 fields.
Two new tests assert specific decoded values, not just "build succeeds".

Add xce_job_state_query_req()/xce_job_state_report_req() to request.c,
paginating job IDs / job-state entries across OPCode_jobStateQuery /
OPCode_jobStateReport messages via direct Request.body union arms
(mirroring xce_jobdispatch_req/xce_notify_req's direct-send shape, not
xce_push_data_req's XceData-table multiplexing -- these are dedicated
union arms, not multiplexed push/reply-get traffic). 8 round-trip tests
(normal/empty/multi-page for both query and report, covering all 4
JobStateStatus values and both queried states) all pass.

Discovered live during task 1.4 development: xceadmin's controller.capnp
copy is freshly synced from src/schema/ on every /xce-build xceadmin run
(meson-build.sh), so task 1.1's two new ClusterConfig fields already
broke the checked-in golden-fixture tests (test_golden_fixture_matches_
checked_in_expected_bin[minimal/full]) by changing the binary's wire
layout. Deeper gap: neither field has a YAML->binary configuration path
at all (unlike their own cited precedent, heartbeatInterval/
inactiveHeartbeatCount, which is wired into both xce.schema.json and
mapping.py) -- the original design review never scoped xceadmin as a
boundary. Added design.md Boundary Commitments addendum + tasks.md
task 1.5 to close both gaps together.

Worker-side C test infrastructure (src/worker/testsuite/, 5 passing
tests, meson suite:'worker' registration) already exists, built by
component-failover-adoption (2026-08-11), weeks before this spec was
written -- task 1.3's "no testsuite exists" premise was sourced from
stale steering docs (structure.md, testing.md, build-deployment.md).
Confirmed directly: fresh build + meson test --suite worker, 5/5 OK.
No source changes needed. Recorded the correct convention task 4.2 must
follow (per-file Unity executable + explicit test() registration, not
a controller-style aggregator runner) in tasks.md's Implementation Notes.

Add XCE_WORKER_RECONCILING status bit (0x00800000, next in the existing
sequential bitmask) + IS_WORKER_RECONCILING macro mirroring
IS_WORKER_UNAVAIL's shape, and resync_state_t (round_token,
queried_jobids array+count, deadline) referenced via a nullable
worker_t.resync pointer -- NULL when no reconciliation round is
outstanding. Compiles and is reachable, unused by any caller yet.

Add OPCode_jobStateQuery/OPCode_jobStateReport, JobStateEntry/
JobStateQuery/JobStateReport structs (paginated, mirroring JobData/
WorkerData/ResourceVals' {ntotal,pos,count} shape), and
workerResyncWindowMs/workerResyncTimeoutMs ClusterConfig fields to
controller.capnp, plus the companion typemap.h/clusterconfig.h C type
declarations this codebase's capnp $C.mapname codegen requires to
compile. Both new opcodes are fire-and-forget (Request.body union only,
no RequestReply arm), matching design.md and the push/notify precedent.

Design validation (2026-09-01) found and fixed 4 issues: a stale bug-1678
citation blocking reuse of persist_submit_job_dispatch_fact, missing
XCE_WORKER_RECONCILING accounting against scheduler-dispatch-commit's
dispatch-fail retry/terminal-fail classification, bug-1631 reactivation
(job.allocs never released on RUN->PEND reconciliation), and an eager-vs-
deferred mutation inconsistency between the new job.c functions and the
bug-1679 explicit-notify precedent. design.approved and tasks.approved
both set; tasks.md drafted (7 major/19 sub-tasks) and passed two rounds
of independent task-graph sanity review.
