 # bug-1943: xce_scheduler --sim does not load user and host groups, so group-scoped limits differ from live

 - 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
+Only `sched_init_config()` (`scheduler.c`, live) called `groupmgr_load_configs`; the core `CONFIG_PUSH` event (`core_events.c:xce_core_push_events`) and the replay snapshot loader (`snapshot_load.c:xce_sched_core_load_snapshot`, from which `sim_bootstrap_limit_plugin` seeds limits) never loaded groups. Pre-existing.
 
 ## Fix
-TODO: required for fixed/partial
+`core.h`/`core.c`: new `xce_core_load_groups()` is the single loader, called from `sched_init_config()` (replacing its direct calls), the `CONFIG_PUSH` event (first) and `snapshot_load.c` (before the limit plugin is seeded); `snapshot.c` field-completeness note updated. Follow-up: limits are not re-seeded on a mid-replay CONFIG_PUSH.
 
 ## 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_user_group_limit_matches_in_sim_as_in_live` (`src/scheduler/testsuite/test_sim_group_limit_parity.c`): RED `:318: FAIL: Expected 1 Was 0 (sim must match the user-group-scoped limit)`, and with only the CONFIG_PUSH part reverted `:334: FAIL: CONFIG_PUSH must register the config's user groups`, GREEN after.
+- 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)
