Split dispatch_a_job_()'s combined "(w->ep == NULL) || (w->host.status
!= 0)" check into two branches, checked in order: w->ep == NULL now
resolves directly via record_job_reconcile_pending_fact() (task 2.1) --
no dispatch_fail_count increment, no mark_job_fail(), never reaching
xce_classify_dispatch_fail() at all -- before the code ever tests
w->host.status != 0, which keeps its existing retry-then-terminal-fail
behavior completely unchanged (byte-identical body, confirmed against
HEAD).
Completes Task 2 (all controller job-table reconciliation outcomes:
2.1 reconcile-to-pending, 2.2 reconcile-assign, 2.3 this split).
RED phase caught a genuine pre-existing test bug: test_worker_notready_
resolves_retryable was seeding a NULL-ep worker while claiming to test
the host.status!=0 retry path -- it never actually exercised that path.
Corrected to use a connected-but-busy worker, with self-asserting
TEST_ASSERT_NOT_NULL(w->ep)/TEST_ASSERT_TRUE(status!=0) guards so this
can't silently drift again.
2 new tests, including a full JOB_TRANSITION_APPLIED path proof (WAL
LSN advance, hook-fires-exactly-once per bug-1679, allocs released per
bug-1631) through this exact call site, both using correctly-timed
canary references on both the job and worker objects to catch any
over-release under ASAN. Full controller suite: 1227 tests, 0 failures,
zero regressions across every other dispatch_a_job_ failure site.
