Revise/invalidate the accepted dependency interpretation and prescribe the exact generated-row wording before TurnEvents planning continues.",

"summary": "Session run-472955e277202c411388c66b fresh pinned-binary capture contradicts the accepted dependency interpretation that EventStorage get/create initializes a miss-path temporary TurnEvents EvTurn to zero before append. In 0x00885380, local TurnEvents begins at [EBP-0x24]: 0x008853fc writes vptr, and 0x00885403/06/09 zero only nested-vector pointers at +0x08/+0x0c/+0x10. No instruction writes temporary EvTurn at [EBP-0x20] before 0x00885413 calls append. Append 0x00884d62 copies source+0x04 into destination+0x04, so the newly appended element transiently receives the uninitialized stack word; 0x0088542d overwrites the stored element EvTurn with the requested turn after temporary nested-vector destruction. SURVIVES: exact get/create ABI, full last-match scan, final returned bucket pointer, final requested-turn publication, deep nested-vector copy, and temporary nested-vector cleanup. QUALIFIED: miss-path append lifetime and unwind remain static-only. OVERTURNED: research-completion-abi/recovered-static.md statement that the temporary starts with turn zero and append deep-copies zero. No live behavior, VM, Ghidra or engine code ran. Pause affected TurnEvents architecture encoding and readiness.",
