Run order:
@@ -161,6 +162,7 @@ Run order:
6. `shutter-0093-bit-isolation.json`: isolates the `0x0093` bits after bench evidence showed this selector also controls white-balance and black/flare lamps.
7. `shutter-0093-blackflare-auto-candidates.json`: uses the known `0x9020` black/flare-manual context and adds each remaining bit to hunt for the `0xFFFF` black/flare-AUTO effect.
8. `shutter-0093-blackflare-slow-marked.json`: repeats the hunt without clear/OK resets between candidates, so white-balance should flicker less and black/flare AUTO transitions can be matched to candidate holds.
9. `shutter-0093-blackflare-field-groups.json`: tests multi-bit field groups after the slow-marked run suggested black/flare AUTO is not one single extra bit over `0x9020`.

| `shutter-0093-gate-ffff` | `E000[0x0093]` read back as `0xFFFF` | white-balance PRESET lamp on, black/flare AUTO lamp on | another `0x0093` bit overrides/selects black/flare AUTO when all bits are set |
| `shutter-0093-bit-isolation` | stepped through `0x1000`, `0x0020`, `0x1020`, `0x8000`, `0x8020`, `0x9000`, `0x9020` | white-balance lamps swapped between MANUAL and PRESET; black/flare stayed MANUAL | bit 15 remains the prime white-balance PRESET candidate; black/flare AUTO is likely outside bits 15/12/5 |
| `shutter-0093-blackflare-auto-candidates` | stepped through `0x9020`, `0xFFFF`, then `0x9020` plus each remaining bit | black/flare swapped AUTO/MANUAL more slowly than white-balance MANUAL/PRESET | the clear/OK reset before each candidate likely caused extra white-balance flicker; use the slow-marked follow-up to map black/flare transitions to exact bits |
| `shutter-0093-blackflare-slow-marked` | held `0x9020`, `0xFFFF`, then alternated `0x9020` with each candidate | white-balance stayed stable, black/flare swapped twice with large pauses; panel stayed `CONNECT: OK` throughout | likely only the manual-reference to `0xFFFF` and `0xFFFF` back to `0x9020` changed black/flare, so AUTO is probably a multi-bit field rather than one added bit |
| `shutter-008f-evs-clear-control` | `0x008F` writes acknowledged as `0x0800`, `0x0000`, `0x0800` | SHUTTER swapped between EVS and OFF while iris AUTO lamp stayed on | `0x008F` is a packed shutter/display status word; clearing it does not simply mean "blank" |
| `shutter-008f-evs-timeout-control` | only `0x008F=0x0800` was sent after OK seed | EVS/iris AUTO, then `CONNECT:NOT ACT` | later blanking is timeout cleanup, not selector-clear evidence |
