 # bug-1941: xce_controller refuses kill/stop/resume of running jobs on hosts whose status is not exactly OK
@@ -40,15 +41,16 @@ Any other status bit (CLOSED_BY_ADMIN, BUSY, UNAVAIL...) makes the control reque
 - Frequency: deterministic (by code reading; confirmed by the RED test of the fix)
 - Evidence: the code sites quoted in Description; no logs kept.
 ## Root cause
-TODO: required for fixed/partial
+`job_ctrl()` (`src/controller/job.c`) sent control only if `w->host.status == 0` and returned `-errno` otherwise. Pre-existing FIXME.
 
 ## Fix
-TODO: required for fixed/partial
+`job.c`: new `job_ctrl_to_host()` sends whenever the worker is connected (endpoint present, not UNAVAIL), so CLOSED/CLOSED_BY_ADMIN/BUSY/locked hosts work; an unknown or unconnected host fails with `-E_XCE_BAD_WORKER` and an error log naming it.
 
 ## Verification
-- Test: TODO: name + file; RED before the fix, GREEN after
-- Suites: TODO: suite results and build profile
-- Live: TODO: soak/deploy run, or n/a and why
+- Test: `test_jc_connected_flagged_host_is_controllable` and `test_jc_unconnected_host_fails_with_bad_worker` (`src/controller/testsuite/test_job_ctrl_hosts.c`): RED `:239: FAIL: Expected 0 Was -2 (status 0x100000)` and `Expected -10002 Was -22`, GREEN after (asserts the decoded request in the worker send queue).
+- Suites: `xce-build.sh all asan xce.build --incremental` on the merged branch, 2026-10-10: all C suites Ok 155 / Fail 0, frontend Go unit tests ok, xceadmin tests ok; apiserver `CGO_ENABLED=0 go test ./...` (incl. middleware, router, cmd) ok
+- Live: n/a: unit/fixture-level verification only; no live deployment was run (follow-up)
