+
+#### HE35a: direct compare `cmd=0x00-0x03` under `20 D0`
+
+Results:
+
+- `cmd=0x00` -> heartbeat only
+- `cmd=0x01` -> repeated:
+  - `07 80 40 24 DD 64`
+- `cmd=0x02` -> heartbeat only
+- `cmd=0x03` -> new sibling:
+  - `07 80 20 12 97 78`
+
+So `0x01` is **not** the only responsive command in the early `20 D0` region,
+but it is still the clearest `0x40`-family member.
+
+#### HE35b: repeat only `cmd=0x01 @ 20 D0`
+
+Target frame:
+
+- `00 00 01 20 D0 AB`
+
+Serial result:
+
+- first useful response appeared on the second send
+- observed:
+  - `07 80 40 24 DD 64`
+  - then one more fragmented repeat of the same family
+- after that, the run returned to plain heartbeat even though the frame kept
+  repeating
+
+Panel-side observation:
+
+- `CONNECT NOT ACT` reportedly stayed off until the script finished
+
+Read:
+
+- this looks like a **one-shot branch opener with continued timeout suppression**
+- the payload still matters after the serial branch is spent, at least at the
+  LCD/state-timer level
+
+#### HE35c: repeat only `cmd=0x01 @ 00 80` baseline control
+
+Target frame:
+
+- `00 00 01 00 80 DB`
+
+Serial result:
+
+- first useful response again appeared on the second send
+- observed several copies of:
+  - `07 80 40 20 D8 65`
+- after that, the run also returned to plain heartbeat while the frame kept
+  repeating
+
+Panel-side observation:
+
+- `CONNECT NOT ACT` reportedly also stayed off until the script finished
+
+Read:
+
+- this weakens the stricter interpretation that only `20 D0` delays the LCD
+  timeout
+- repeated `cmd=0x01` traffic under both payloads appears capable of holding
+  the panel out of `CONNECT NOT ACT` while the stream is active
+
+Current best interpretation after HE35:
+
+- the distinctive thing about `20 D0` is still the **response family shift**
+  from:
+  - `07 80 40 20 D8 65`
+  to:
+  - `07 80 40 24 DD 64`
+- but the timeout-holding effect may belong more broadly to sustained repeated
+  `cmd=0x01` traffic than to `20 D0` alone
+- `cmd=0x03 @ 20 D0` is now worth treating as a second live lead because it
+  opened:
+  - `07 80 20 12 97 78`
+
+Best next follow-up from HE35:
+
+1. run `HE35d` slow `cmd=0x01 @ 20 D0` to separate content from cadence
+2. run `HE35e` neighboring repeats to see whether `0x00`, `0x02`, or `0x03`
+   also suppress `CONNECT NOT ACT`
+3. consider a matched repeat on `cmd=0x03 @ 20 D0` because it now has its own
+   distinct structured family
+
+### HE35 Follow-Up: Slow + Neighbor Repeats
+
+Additional capture files present:
+
+- `captures/he35-repeat-cmd01-20d0-slow.txt`
+- `captures/he35-repeat-cmd00-20d0.txt`
+- `captures/he35-repeat-cmd02-20d0.txt`
+- `captures/he35-repeat-cmd03-20d0.txt`
+
+Panel-side observation from this pass:
+
+- all of these additional runs reportedly kept the LCD in the same "clear"
+  state while the script was running
+
+That is important because it means the timeout-holding effect is **not** unique
+to repeated `cmd=0x01`.
+
+#### HE35d: slow repeat of `cmd=0x01 @ 20 D0`
+
+Target frame:
+
+- `00 00 01 20 D0 AB`
+
+Serial result:
+
+- second send still opened the same family:
+  - `07 80 40 24 DD 64`
+- it produced a larger one-shot burst than the faster repeat
+- after that, the stream returned to heartbeat for the rest of the run
+
+Read:
+
+- slowing the cadence to `1.5 s` did **not** kill the branch
+- so this is not purely a "dense traffic only" effect
+
+#### HE35e-1: repeat only `cmd=0x00 @ 20 D0`
+
+Target frame:
+
+- `00 00 00 20 D0 AA`
+
+Serial result:
+
+- second send opened a new sibling:
+  - `07 80 40 48 3A EF`
+- then the run fell back to heartbeat
+
+Read:
+
+- `cmd=0x00 @ 20 D0` is not heartbeat-only after all
+- it appears to open its own `0x40`-family sibling under repetition
+
+#### HE35e-2: repeat only `cmd=0x02 @ 20 D0`
+
+Target frame:
+
+- `00 00 02 20 D0 A8`
+
+Serial result:
+
+- second send opened:
+  - `07 80 20 12 87 68`
+- then returned to heartbeat
+
+Read:
+
+- this makes the `0x02/0x03 @ 20 D0` region look like a small structured
+  `0x20 0x12 ...` family surface, not a one-off anomaly
+
+#### HE35e-3: repeat only `cmd=0x03 @ 20 D0`
+
+Target frame:
+
+- `00 00 03 20 D0 A9`
+
+Serial result:
+
+- second send opened:
+  - `07 80 20 12 97 78`
+- then returned to heartbeat
+
+Read:
+
+- `0x03 @ 20 D0` behaves consistently with the direct-compare run
+- it is the stronger `0x20 0x12 ...` sibling of the `0x02` branch
+
+Current read after the full HE35 pass:
+
+- the low `0x00-0x03` command region under `20 D0` is now clearly structured:
+  - `0x00` -> `07 80 40 48 3A EF`
+  - `0x01` -> `07 80 40 24 DD 64`
+  - `0x02` -> `07 80 20 12 87 68`
+  - `0x03` -> `07 80 20 12 97 78`
+- each branch still looks one-shot on the serial side
+- but repeated traffic from this small region appears sufficient to hold the LCD
+  out of `CONNECT NOT ACT` while the script is active
+
+That suggests a better model:
+
+- these frames may not be "the wake command"
+- but they do look like a **low-command session-presence/status surface**
+- and different command bytes select neighboring structured families within it
+
+### HE36: Low-Command Mixer + Broadened Keep-Alive Search
+
+Goal: test whether mixing the known low-command `20 D0` frames does more than
+repeating one at a time, and broaden the search to nearby commands that might
+belong to the same "keep-alive-ish" session-presence surface.
+
+Known live low-command `20 D0` frames so far:
+
+- `00 00 00 20 D0 AA`
+- `00 00 01 20 D0 AB`
+- `00 00 02 20 D0 A8`
+- `00 00 03 20 D0 A9`
+
+#### HE36a: maintained 4-frame mixer, medium cadence
+
+```powershell
+python scripts/serial_sequence_probe.py --port COM5 --prompt --prompt-screen --pre-read 2.0 --frame "00 00 00 20 D0 AA" --frame "00 00 01 20 D0 AB" --frame "00 00 02 20 D0 A8" --frame "00 00 03 20 D0 A9" --repeat 10 --frame-interval 0.50 --read-after-frame 0.20 --read-after-group 0.80 --log captures/he36-mixer-20d0-00-03-medium.txt
+```
+
+What to watch:
+
+- whether the LCD stays clear / non-`CONNECT NOT ACT`
+- whether new structured families appear beyond the known one-shot siblings
+- whether the mixed stream looks "more alive" than any single-frame repeat
+
+#### HE36b: maintained 4-frame mixer, slow cadence
+
+```powershell
+python scripts/serial_sequence_probe.py --port COM5 --prompt --prompt-screen --pre-read 2.0 --frame "00 00 00 20 D0 AA" --frame "00 00 01 20 D0 AB" --frame "00 00 02 20 D0 A8" --frame "00 00 03 20 D0 A9" --repeat 8 --frame-interval 1.20 --read-after-frame 0.25 --read-after-group 1.20 --log captures/he36-mixer-20d0-00-03-slow.txt
+```
+
+Purpose:
+
+- separate "this class matters" from "the panel only likes brisk chatter"
+
+#### HE36c: 2-frame split mixers by family
+
+`0x40`-leaning pair:
+
+```powershell
+python scripts/serial_sequence_probe.py --port COM5 --prompt --prompt-screen --pre-read 2.0 --frame "00 00 00 20 D0 AA" --frame "00 00 01 20 D0 AB" --repeat 12 --frame-interval 0.60 --read-after-frame 0.20 --read-after-group 0.80 --log captures/he36-mixer-20d0-40pair.txt
+```
+
+`0x20 0x12`-leaning pair:
+
+```powershell
+python scripts/serial_sequence_probe.py --port COM5 --prompt --prompt-screen --pre-read 2.0 --frame "00 00 02 20 D0 A8" --frame "00 00 03 20 D0 A9" --repeat 12 --frame-interval 0.60 --read-after-frame 0.20 --read-after-group 0.80 --log captures/he36-mixer-20d0-20pair.txt
+```
+
+Purpose:
+
+- see whether one subfamily is better at holding the panel clear
+- or whether mixing both subfamilies is what helps
+
+#### HE36d: broadened direct sweep `0x04-0x0F @ 20 D0`
+
+```powershell
+python scripts/serial_direct_response_sweep.py --port COM5 --prefix1s 0x00 --prefix2s 0x00 --commands 0x04-0x0F --states 0x20 --values 0xD0 --settle 3.0 --after-each 0.8 --after 2.0 --pause-on-anomaly --log captures/he36-direct-20d0-cmd04-0f.txt
+```
+
+Purpose:
+
+- look for more neighboring "keep-alive-ish" branches without re-running the
+  whole `0x00-0xFF` space
+- map whether this structured low-command surface extends further upward
+
+#### HE36e: broader direct sweep `0x10-0x1F @ 20 D0`
+
+```powershell
+python scripts/serial_direct_response_sweep.py --port COM5 --prefix1s 0x00 --prefix2s 0x00 --commands 0x10-0x1F --states 0x20 --values 0xD0 --settle 3.0 --after-each 0.8 --after 2.0 --pause-on-anomaly --log captures/he36-direct-20d0-cmd10-1f.txt
+```
+
+Purpose:
+
+- test whether the same effect is really a "low command region" phenomenon
+- or mostly a tight `0x00-0x03` pocket
+
+#### HE36f: single-frame repeats for any new HE36d/e hits
+
+If `HE36d` or `HE36e` turn up new live candidates, repeat them individually with
+the same pattern used in HE35:
+
+```powershell
+python scripts/serial_probe_response.py --port COM5 --tx-frame "<candidate frame>" --repeat 20 --interval 0.50 --delay 3 --after 3 --frame-size 0 --log captures/he36-repeat-<candidate>.txt
+```
+
+Use this only for commands that actually produce a structured family in the
+direct sweep.
+
+#### Recommended order
+
+1. `HE36a` 4-frame medium mixer
+2. `HE36c` split mixers
+3. `HE36b` 4-frame slow mixer
+4. `HE36d` broadened `0x04-0x0F` sweep
+5. `HE36e` broadened `0x10-0x1F` sweep
+6. `HE36f` repeat any new hits individually
+
+Interpretation guide:
+
+- if the mixer holds the LCD clear **and** produces richer serial behavior,
+  we may be getting closer to a maintained background stream class
+- if the mixer holds the LCD clear but still stays serially one-shot, that
+  still supports a "session-presence without full activation" model
+- if `0x04-0x1F @ 20 D0` reveals more structured siblings, then this is likely
+  a broader maintained low-command surface rather than just a four-command oddity
+

+- `captures/he36-direct-20d0-cmd10-1f.txt`
+
+#### Mixer behavior
+
+The mixer runs were surprisingly consistent:
+
+- they did **not** open deeper multi-turn branches
+- they mostly produced the same early one-shot family behavior in group 1
+- after that, the stream settled into heartbeat-compatible traffic while the
+  script continued
+
+The practical implication is still important:
+
+- the mixed low-command stream behaves like a stable maintained background
+  surface
+- but not yet like a full session activator
+
+The split-pair mixers behaved the same way:
+
+- `00/01` pair stayed on the `0x40` side
+- `02/03` pair stayed on the `0x20 0x12` side
+- neither pair triggered a richer second-stage exchange
+
+#### Broadened direct sweep: `0x04-0x0F @ 20 D0`
+
+This region is definitely live and patterned:
+
+- `0x05` -> `07 80 41 24 DD 65`
+- `0x07` -> `07 80 10 09 D7 13`
+- `0x09` -> `07 80 42 24 DD 66`
+- `0x0B` -> `07 80 21 12 17 F9`
+- `0x0D` -> `07 80 43 24 DD 67`
+
+#### Broadened direct sweep: `0x10-0x1F @ 20 D0`
+
+The pattern extends cleanly upward:
+
+- `0x11` -> `07 80 44 24 DD 60`
+- `0x13` -> `07 80 22 12 97 7A`
+- `0x15` -> `07 80 45 24 DD 61`
+- `0x17` -> `07 80 11 09 D7 12`
+- `0x19` -> `07 80 46 24 DD 62`
+- `0x1B` -> `07 80 23 12 17 FB`
+- `0x1D` -> `07 80 47 24 DD 63`
+
+Current best structural read:
+
+- the low `20 D0` command region is not just a tiny `0x00-0x03` pocket
+- it extends at least through `0x1D` with repeating family structure
+- the active commands are mostly the odd ones in the region
+- and the responses appear to cluster into at least three sibling families:
+  - `07 80 4x 24 DD 6x`
+  - `07 80 2x 12 .. ..`
+  - `07 80 1x 09 D7 1x`
+
+That is a much stronger hint that we are seeing a real maintained status/control
+surface rather than random one-shot exceptions.

    LCD behavior
 - That suggests `20 D0` may be a more session-like or status-like host payload
  pair than `00 80`, even though it still does not by itself wake the panel.
+- A later targeted follow-up refined that further:
+  - `cmd=0x01 @ 20 D0` repeatedly opened `07 80 40 24 DD 64`
+  - `cmd=0x01 @ 00 80` repeatedly opened `07 80 40 20 D8 65`
+  - `cmd=0x03 @ 20 D0` also opened a second distinct family:
+    `07 80 20 12 97 78`
+  - in both repeated-`cmd=0x01` tests, the panel reportedly stayed out of
+    `CONNECT NOT ACT` until the script ended
+- So the clearest difference between `20 D0` and `00 80` is currently the
+  **family selected** by repeated `cmd=0x01`, while the timeout-holding effect
+  may be a broader property of sustained repeated `cmd=0x01` traffic.
+- A broader HE35 follow-up then showed that the early `0x00-0x03` command
+  region under `20 D0` is itself structured:
+  - `0x00` -> `07 80 40 48 3A EF`
+  - `0x01` -> `07 80 40 24 DD 64`
+  - `0x02` -> `07 80 20 12 87 68`

+- All of those still looked one-shot on the serial side, but the user reported
+  the LCD stayed in the same clear/non-`CONNECT NOT ACT` state while the repeat
+  scripts were active.
+- That makes the low `0x00-0x03 @ 20 D0` area look less like a single magic
+  wake frame and more like a small session-presence/status surface.
+- A broader HE36 pass strengthened that further:
+  - the active pattern extends at least through `0x1D @ 20 D0`
+  - and it is mostly the odd commands that answer
+  - examples:

+    - `0x1D` -> `07 80 47 24 DD 63`
+    - interleaved siblings also appear in `0x10 0x09 D7 ..` and
