 ## Implementation Notes
 - `xce-build.sh` resolves a relative build dir under `src/`: `bash src/tools/xce-build.sh lib asan xce.build.alloceq` builds into `src/xce.build.alloceq`, so iterate with `meson test -C src/xce.build.alloceq`.

 - Simulation mode (`sim_loop.c`) still takes its own session-begin clock reading before `xce_core_begin_session()`; by design that is left to spec scheduler-sim-discrete-clock (3.1 fixed only the normal-mode recorder).
 - 4.2 left the `from`-excluded comments at `test_sim_verify.c` ~639-681 for 4.3, which inverts the test they document.
 - `sim_verify.c` builds descriptions with `vsnprintf` + `malloc`, not `vasprintf`: about 25 scheduler tests `#include "../src/sim_verify.c"` after `<stdio.h>` without `_GNU_SOURCE`. Same ownership contract as libxce.
+- 5.2: `xce-build.sh all` stops at the xceadmin live-HA e2e test (`test_live_config_push_against_primary_reaches_success_path`, versionTag 0); it uses controller binaries from the shared default build dirs, not this build. The spec needs only lib/scheduler/controller: built with `--incremental` per component, then `meson test --no-suite xceadmin` gave 116/116, 0 Unity :FAIL lines, 0 sanitizer reports.
