Validate one fixed anchor against Controller range 3 and Link range 1, recover the exact owned Controller Link, diagnose Energy and active body parts, preserve move, withdraw, and upgrade return codes, and verify later position, Store, or event evidence.
Route every Safe Mode request through one final per-tick dispatcher, bind the exact Controller ID, disable the request before activateSafeMode(), and verify activation consumption on the next tick.
Enter Controller recovery with hysteresis, reject blocked or unready attempts, submit one upgrader action, and verify the exact Creep in the next tick's room event log.

English articles are published only after source review, official API checks where applicable, JavaScript syntax review where code is present, duplicate-intent and link checks, and editorial review. Publication does not imply Console or multi-tick live-room verification; those evidence states remain separate in each guide. Review the verification method.
