v0.306.0: R-570 — the off-site note decides on its kind only; the pre-0.251.0 text fallback is deleted

Fleet condition read on each box's settings.json 2026-10-10 (offbox.last_success ~02:16Z on 0.304.0).
Red-proof: the new no-kind row of TestR553_StaleNoteDecisionSurvivesWordingChange failed against the fallback.
