    "Follow-up after the slow-marked run: black/flare swapped only twice, likely on 0x9020 -> 0xFFFF and back to 0x9020.",
    "That suggests black/flare AUTO is not one single extra bit over 0x9020, but a multi-bit mode field.",
    "Each candidate is preceded by 0x9020 manual context. Record whether black/flare changes during the candidate hold."
