v0.308.0: controller batch 2026-10-12 — clear-address warning (R-922), secret sweep over every page (R-255), read_failed (R-266), no NVMe heat band (R-333), share globe (R-577), Hungarian dates and numbers (R-562), lost-drive option pinned (R-521)

Operator rulings 2026-10-12, 09 §3 decisions 196, 204-207, 223, 227. MinAgent 0.131.0 unchanged.
R-255's sweep found one leak, fixed here: an optional-config secret_input was rendered into its
settings page; it is now revealed on demand. Hungarian parity fixtures re-captured once for R-562.
