# bug-1938: xce_scheduler dispatches jobs from closed or inactive queues (queue readiness gate is a stub)

## Description
**Observed:** (source reading, `.kiro/reviews/project-gap-review-2026-10-10.md` (P0); to be confirmed by a failing test before the fix)
The admin queue controls set and clear the closed/inactive flags (`src/controller/queue.c:131-152`), but the scheduler's gates always pass:
```c
/* FIXME this is just stub, we need to add more */
int sched_job_is_ready(xce_sched_job_t* j) { return 1; }
/* FIXME this is just stub, we need to add more */
int sched_queue_is_ready(xce_sched_queue_t* q) { return 1; }   /* core.c:646-649 */
```

**Expected:** Jobs of an inactive queue are not dispatched (they stay pending with a reason); a closed queue accepts no new submissions.
**Impact:** Admin queue control silently ignored: inactivating a queue does not stop dispatch.
**Found by:** review: `.kiro/reviews/project-gap-review-2026-10-10.md` (P0)
## Environment
- OS: no /etc/os-release; Docker container; NixOS kernel; kernel Linux 6.18.33 x86_64
- libc: glibc 2.42-47 (interpreter /nix/store/wb6rhpznjfczwlwx23zmdrrw74bayxw4-glibc-2.42-47/lib/ld-linux-x86-64.so.2)
- Toolchain: gcc (GCC) 15.2.0, meson 1.9.1
- Build: asan (xce.build)
- Code: scheduler-framework @ 94472ee3-dirty
- Deployment: any (found by source reading; the failing test that confirms it is named in Verification)

## Reproduction
1. Deploy a cluster, inactivate queue `normal` (queue control), submit a job to it.
2. The job is dispatched and runs.
- Frequency: deterministic (by code reading; confirmed by the RED test of the fix)
- Evidence: the code sites quoted in Description; no logs kept.
