   - The 11 removed test files' `.c` sources are left on disk at their current `src/controller/testsuite/` path for now (referenced by no build target) — task 2.1 physically relocates them together with `test_test_cli.c`/`test_xcetest_process_entry.c`
   - Observable: a harness-scoped build produces an `xce_test` binary; a controller-scoped build run immediately after this single task (no later tasks applied) still succeeds, `controller_unit_test`'s reported test count has dropped by exactly the 11 removed entries, and none of the four standalone binaries are defined anymore
   - _Requirements: 1.1, 1.2, 1.3, 2.1, 2.2, 2.4_
-- [ ] 1.2 Promote the shared ctrlstatus_fmt.h header and repoint its current consumers
+- [x] 1.2 Promote the shared ctrlstatus_fmt.h header and repoint its current consumers
   - Move `ctrlstatus_fmt.h` to `src/include/xce/`; update the include path in harness's `test.c` and `joblist_display.c` (already relocated in 1.1) and in controller's `test_ctrlstatus.c`
   - `joblist_display.c`'s own test file, `test_joblist_display.c`, still lives in `src/controller/testsuite/` at this point and is intentionally left untouched here — its include-path fix happens in task 2.2, when that file relocates
   - Observable: a repo-wide search finds no remaining relative `#include "ctrlstatus_fmt.h"`; all three current consumers include it from `xce/ctrlstatus_fmt.h`
