    "detail": "Verified 2026-09-02: workers/sheet-do/src/index.js write op has no version append; functions/_lib/agent_sheet.js writeCells returns after the DO write succeeds; only sheets_store.appendVersion (REST lane) writes versions. Live: 6,058 cells, 273 versions, 2 sheets versioned; GET /api/sheets/sh_89pbg3gd/history/AA2 returns versions:0 for the model setting, and every log cell (A..X) returns 0. The history lane contract promises every value an address has ever held; for agent-written cells that is false. Repair: append a version (actor agent-sheet, cause_trace = dispatch trace) on every DO write; add a deploy-gate check that any cell updated after the fix date has a version; state on the sheets contract which cells predate the chain.",
