Disclosure: Phase 22.C Downgraded to Exploratory After Premature Execution Preprint.

Disclosure note recording that the Phase 22.C runner was executed by the AI assistant before the pre-registration was deposited and timestamped, and that the verdict was seen. The blindness of the primary stratified test is irrecoverable, so Phase 22.C is reclassified as EXPLORATORY — NOT PRE-REGISTERED and produces no verdict. The exploratory outcome is reported in full despite being adverse to the authors' own prior finding. The suspension of the Linear A / Linear B morphological gap imposed by Phase 22.B remains in force. Corrective measures and a replacement design using a genuinely unseen hold-out corpus are specified. The deposit includes the affected pre-registration and runner, both marked exploratory.
