|

- The next useful probe should probably target `07 80 7A 50 26 D1` directly, or
|
||||
compare exact-vs-host handling of `7A` rather than `FA`.
|
||||
|
||||
### HE10: Exact Echo Of `07 80 7A 50 26 D1`
|
||||
|
||||
Recreate the host-shaped `E8` path that now reproducibly yields
|
||||
`07 80 7A 50 26 D1`, then immediately send that exact `7A` frame back.
|
||||
|
||||
```powershell
|
||||
python scripts/serial_sequence_probe.py --port COM5 --prompt --frame "00 00 A0 00 80 7A" --frame "00 00 E8 40 30 C2" --frame "07 80 7A 50 26 D1" --frame "00 00 00 00 80 DA" --frame "00 00 00 00 80 DA" --repeat 2 --frame-interval 0.20 --read-after-frame 0.30 --read-after-group 0.8 --log captures/rcp-heartbeat-echo-exact-7a5026d1.txt

### HE11: Host-Shaped Mirror Of `07 80 7A 50 26 D1`
|
||||
|
||||
Host-shaped checksum for `00 00 7A 50 26 ??` is `56`.
|
||||
|
||||
```powershell
|
||||
python scripts/serial_sequence_probe.py --port COM5 --prompt --frame "00 00 A0 00 80 7A" --frame "00 00 E8 40 30 C2" --frame "00 00 7A 50 26 56" --frame "00 00 00 00 80 DA" --frame "00 00 00 00 80 DA" --repeat 2 --frame-interval 0.20 --read-after-frame 0.30 --read-after-group 0.8 --log captures/rcp-heartbeat-echo-host-7a5026.txt

```
|
||||
|
||||
What would count as a hit:
|
||||
|
||||
- any new non-heartbeat response after the `7A` echo or mirror
|
||||
- a stable second-stage family after `07 80 7A 50 26 D1`
|
||||
- recurrence of `FA`, `7A`, or another new `50`-region family
|
||||
- any visible panel behavior change beyond the usual `CONNECT NOT ACT`

### 2026-05-13 `7A` Echo Follow-Up Result

- `captures/rcp-heartbeat-echo-host-7a5026.txt`
|
||||
|
||||
Result summary:
|
||||
|
||||
- Both runs again point to the host-shaped `E8` step as the meaningful branch
|
||||
trigger.
|
||||
- In group 1, `00 00 E8 40 30 C2` reproduced `07 80 7A 50 26 D1` in both tests.
|
||||
- The exact-echo run was the cleanest:
|
||||
- `00 00 E8 40 30 C2` produced one `07 80 7A 50 26 D1`
|
||||
- exact echo `07 80 7A 50 26 D1` produced only heartbeat afterwards
|
||||
- The host-shaped mirror run behaved like the earlier `FA` tests:
|
||||
- `00 00 E8 40 30 C2` produced `07 80 7A 50 26 D1` twice
|
||||
- host-shaped `00 00 7A 50 26 56` then only drained one more
|
||||
`07 80 7A 50 26 D1` followed by heartbeat
|
||||
- In group 2, both tests were heartbeat-only after the same sequence.
|
||||
|
||||
Interpretation:
|
||||
|
||||
- `07 80 7A 50 26 D1` is now a confirmed reproducible response family on the
|
||||
host-shaped `E8` branch.
|
||||
- But directly echoing `7A`, whether exact or host-shaped, still did not create
|
||||
a second-stage exchange, visible state change, or reusable session behavior.
|
||||
- This makes `7A` look more like another readable/event family emitted by the
|
||||
branch, not yet like the next host command the panel expects.
|
||||
- The asymmetry is useful:
|
||||
- host-shaped `E8` can provoke `7A`
|
||||
- `7A` itself does not obviously provoke anything back
|
||||
|
||||
Best current model of the `E8` branch:
|
||||
|
||||
- `00 00 E8 40 30 C2` is the active stimulus.
|
||||
- `07 80 7A 50 26 D1` is the most reproducible downstream response in that
|
||||
branch.
|
||||
- `07 80 FA 50 26 51` and `07 C0 7A 50 A6 11` remain side-family observations,
|
||||
but neither has overtaken `7A` as the strongest lead.
