# bug-765: scheduler-controller-msg-gap marked 36/36 [x] but NOT truly implemented: schedUpdateJob notify…

## Description
scheduler-controller-msg-gap marked 36/36 [x] but NOT truly implemented: schedUpdateJob notify path hits the bulk CREATE path (sched_update_existing_job is dead code) → corrupts/duplicates live job state, no -ENOENT; Req 3 broken at dequeue, Req 6 stores nothing (rusage never stored).

## Environment
_Not recorded (migrated from buglog.json)._

## Reproduction
_Not recorded (migrated from buglog.json)._

## Root cause
Tasks were checked [x] without the dequeue/update path and rusage storage actually being wired; gap surfaced only by cross-task re-audit (per-task review missed it).

## Fix
FIXED 2026-06-18 (commits 5c1f715,93124c5,080ff78,276e26c): G-8/G-4 (route notify job-update to in-place sched_update_existing_job, all mutable fields, -ENOENT no-create); G-5 (store rusage on xce_sched_job_t via sched_apply_job_rusage + free_JobRusages_ptr); G-3 (free all 5 killer op payloads with generated deep-freers); G-7 (doc reconciliation — sched_op_name stays static in scheduler.c, lib must not depend on scheduler headers); G-6 (real white-box tests: test_handlers.c 6/6 for 9.2/9.3, test_job_update.c 10/10 for 9.4/9.5/9.7, registered as meson tests). Scheduler suite 31/31 GREEN, ASAN-clean, boundary-clean. validate-impl GO. RESIDUAL (documented, non-blocking): 9.6 dequeue worker-resvals APPLY unit test (dormant path R-3 — enqueue tested), 9.8 documented compile-time absence, 9.9 log-capture gated, 9.2 -ENOMEM fault-injection.
