"title": "Remove the legacy repository clock injection hook",

"status": "ready",

"change_class": "maintenance",

"objective": "Remove the root-level CI-only usercustomize hook after EM-0010 makes reproducible timestamp semantics explicit in the compiler, so validation no longer mutates Python global clock behavior at interpreter startup.",

"acceptance": [

"the root-level usercustomize.py hook is absent",

"CI does not monkeypatch datetime globally at Python interpreter startup",

"make check proves deterministic output through EM-0010 compiler semantics without an environment-specific clock hook",

"the accepted repository remains clean after validation"

],

"limitations": [

"This task does not redefine generated_at semantics; EM-0010 owns that implementation.",

"This task must not be implemented before EM-0010 is accepted."
