The pair I shipped this iteration -- focus_persists on for main_menu, off everywhere else -- reported both halves as agreement with the contract. Nothing measured that extras does not persist. The corpus has EXTRAS' opening item from one entry and (B) restoring the PARENT's focus 4/4; neither says what a submenu's own cursor does on re-entry. Caught by the Decoder. It is the mirror of the trap it was written to avoid. I refused to let a derived menu-wide rule overwrite a measured value, then let 'not measured here' become a positive assertion of the negative. Both treat a gap in the corpus as if it carried information and differ only in which direction they fill it. And the failure mode was the bad one: if the game does persist EXTRAS, the check holds the port to the wrong behaviour and passes while doing it. check_focus_persists now asserts only the measured half. The scope became a separate guard with its own outcome word -- 'only main_menu, AUTHORED DEFAULT, unmeasured elsewhere' -- which still fails if widened, since that should be a deliberate edit, but can no longer be read as the game being known to reset. focus_persists_why records the correction rather than being rewritten. It also weakens a label. EXTRAS' initial_focus is marked measured and was taken on a single entry; now that the main menu is known to remember its cursor, a one-entry reading of any screen may be measuring history rather than what the screen opens on -- the same objection that reframed the TUTORIAL/NEW GAME disagreement. The observation stands, its reading as an initial focus does not. Caveat attached, kind left as measured with a note that it changes if EXTRAS turns out to persist. Not building on the non-persistence half until their EXTRAS re-entry run returns.

Authored decisions
Everything here is a decision we made, not something the disc said. It is
hand-written, committed, and survives a re-export — unlike export/, which is
regenerated wholesale and must never be hand-edited.
Every entry carries a why. When the RE agent decodes the real answer, delete
the entry and let the exporter emit it; that deletion is the measure of
progress.

question each placeholder is standing in for.
