    "The mechanism makes stopping expensive and recorded, not impossible — a determined model can still find an exit. It is a forcing function, not a proof of task completion.",
    "The build brief named install-foundryos-hooks.mjs as a candidate Stop-hook registrar; verified FALSE — that installer registers no Stop hook. The real registrars are install-session-contract-hooks.mjs (ordinary-session gate) and the two-signal-surfacing installer (chassis gate). Recorded as a correction."
