+### HE35: Targeted `20 D0` Follow-Up Ladder
+
+Goal: check whether the interesting part of the `20 D0` sweep is specifically
+`cmd=0x01`, whether nearby commands behave similarly, and whether repeating only
+that one frame delays `CONNECT NOT ACT` by itself.
+
+#### HE35a: direct compare `cmd=0x00-0x03` under `20 D0`
+
+```powershell
+python scripts/serial_direct_response_sweep.py --port COM5 --prefix1s 0x00 --prefix2s 0x00 --commands 0x00-0x03 --states 0x20 --values 0xD0 --settle 3.0 --after-each 1.0 --after 2.0 --pause-on-anomaly --log captures/he35-direct-20d0-cmd00-03.txt
+```
+
+What to watch:
+
+- whether `0x01` is still the only anomaly
+- whether `0x00`, `0x02`, or `0x03` produce siblings
+- whether `CONNECT NOT ACT` appears during the short run
+
+#### HE35b: repeat only `cmd=0x01 @ 20 D0`
+
+Target frame:
+
+- `00 00 01 20 D0 AB`
+
+```powershell
+python scripts/serial_probe_response.py --port COM5 --tx-frame "00 00 01 20 D0 AB" --repeat 40 --interval 0.50 --delay 3 --after 3 --frame-size 0 --log captures/he35-repeat-cmd01-20d0.txt
+```
+
+What to watch:
+
+- whether the panel stays out of `CONNECT NOT ACT` while this one frame repeats
+- whether `07 80 40 24 DD 64` appears again
+- whether the response is one-shot only or repeats periodically
+
+#### HE35c: repeat only `cmd=0x01 @ 00 80` baseline control
+
+Target frame:
+
+- `00 00 01 00 80 DB`
+
+```powershell
+python scripts/serial_probe_response.py --port COM5 --tx-frame "00 00 01 00 80 DB" --repeat 40 --interval 0.50 --delay 3 --after 3 --frame-size 0 --log captures/he35-repeat-cmd01-0080-control.txt
+```
+
+Purpose:
+
+- compare the same command byte under the older baseline payload
+- see whether only `20 D0` delays the timeout-like LCD behavior
+
+#### HE35d: slower repeat of `cmd=0x01 @ 20 D0`
+
+```powershell
+python scripts/serial_probe_response.py --port COM5 --tx-frame "00 00 01 20 D0 AB" --repeat 20 --interval 1.50 --delay 3 --after 3 --frame-size 0 --log captures/he35-repeat-cmd01-20d0-slow.txt
+```
+
+Purpose:
+
+- estimate whether the panel cares about this frame's **content**, or whether it
+  only helps when the cadence is dense enough
+
+#### HE35e: neighboring single-frame repeats under `20 D0`
+
+Neighbor frames:
+
+- `00 00 00 20 D0 AA`
+- `00 00 02 20 D0 A8`
+- `00 00 03 20 D0 A9`

+```
+
+Purpose:
+
+- test whether the timeout effect belongs to the whole early `20 D0` region
+- or whether `cmd=0x01` is the special case
+
+#### Recommended order
+
+1. `HE35a` direct `0x00-0x03` compare
+2. `HE35b` repeat only `cmd=0x01 @ 20 D0`
+3. `HE35c` baseline `cmd=0x01 @ 00 80` control
+4. `HE35d` slow `cmd=0x01 @ 20 D0`
+5. `HE35e` neighboring repeats
+
+Interpretation guide:
+
+- if only `cmd=0x01 @ 20 D0` delays `CONNECT NOT ACT`, that is our best
+  session-like micro-lead so far
+- if `0x00-0x03 @ 20 D0` all help, then this may be an early-page or
+  low-command-region effect rather than a single magic frame
+- if the same effect also appears at `cmd=0x01 @ 00 80`, then the LCD behavior
+  may be more about traffic density than payload meaning
+
+### HE35 Result: `20 D0` Narrowing Pass
+
+Capture files present:
+
+- `captures/he35-direct-20d0-cmd00-03.txt`
+- `captures/he35-repeat-cmd01-20d0.txt`
+- `captures/he35-repeat-cmd01-0080-control.txt`
+
+#### 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

+#### 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.
+
+### HE37: Ordered Camera-State Cycle Hypothesis
+
+Working idea: if we put our "how would Sony have built this in the 1990s?"
+hats on, the panel may be expecting a **fixed scan order** of camera-state pages,
+not just valid packets in any order.
+
+That would explain why:
+
+- repeated single frames can hold the LCD out of `CONNECT NOT ACT`
+- valid mixed traffic can keep the panel semi-alive
+- but we still do not get a full wake-up or richer panel state
+
+The key question here is:
+
+- does an **ordered** low-command `20 D0` cycle behave better than the same
+  frames shuffled?
+
+#### HE37a: ascending ordered low-band cycle `0x00-0x0F`
+
+```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" --frame "00 00 04 20 D0 AE" --frame "00 00 05 20 D0 AF" --frame "00 00 06 20 D0 AC" --frame "00 00 07 20 D0 AD" --frame "00 00 08 20 D0 A2" --frame "00 00 09 20 D0 A3" --frame "00 00 0A 20 D0 A0" --frame "00 00 0B 20 D0 A1" --frame "00 00 0C 20 D0 A6" --frame "00 00 0D 20 D0 A7" --frame "00 00 0E 20 D0 A4" --frame "00 00 0F 20 D0 A5" --repeat 4 --frame-interval 0.35 --read-after-frame 0.15 --read-after-group 1.0 --log captures/he37-ordered-00-0f.txt
+```
+
+Purpose:
+
+- mimic a boring fixed page-scan loop
+- see whether simple ascending order looks better than ad hoc mixing
+
+#### HE37b: shuffled control, same membership as `HE37a`
+
+```powershell
+python scripts/serial_sequence_probe.py --port COM5 --prompt --prompt-screen --pre-read 2.0 --frame "00 00 09 20 D0 A3" --frame "00 00 01 20 D0 AB" --frame "00 00 0D 20 D0 A7" --frame "00 00 05 20 D0 AF" --frame "00 00 03 20 D0 A9" --frame "00 00 0B 20 D0 A1" --frame "00 00 07 20 D0 AD" --frame "00 00 0F 20 D0 A5" --frame "00 00 00 20 D0 AA" --frame "00 00 08 20 D0 A2" --frame "00 00 02 20 D0 A8" --frame "00 00 0A 20 D0 A0" --frame "00 00 04 20 D0 AE" --frame "00 00 0C 20 D0 A6" --frame "00 00 06 20 D0 AC" --frame "00 00 0E 20 D0 A4" --repeat 4 --frame-interval 0.35 --read-after-frame 0.15 --read-after-group 1.0 --log captures/he37-shuffled-00-0f.txt
+```
+
+Purpose:
+
+- same traffic, same cadence, different order
+- direct control for the "expected sequence" hypothesis
+
+#### HE37c: ascending odd-only cycle `0x01-0x1D`
+
+Active responders so far are mostly the odd commands. This run leans into that.
+
+```powershell
+python scripts/serial_sequence_probe.py --port COM5 --prompt --prompt-screen --pre-read 2.0 --frame "00 00 01 20 D0 AB" --frame "00 00 03 20 D0 A9" --frame "00 00 05 20 D0 AF" --frame "00 00 07 20 D0 AD" --frame "00 00 09 20 D0 A3" --frame "00 00 0B 20 D0 A1" --frame "00 00 0D 20 D0 A7" --frame "00 00 11 20 D0 BB" --frame "00 00 13 20 D0 B9" --frame "00 00 15 20 D0 BF" --frame "00 00 17 20 D0 BD" --frame "00 00 19 20 D0 B3" --frame "00 00 1B 20 D0 B1" --frame "00 00 1D 20 D0 B7" --repeat 4 --frame-interval 0.35 --read-after-frame 0.15 --read-after-group 1.0 --log captures/he37-ordered-odd-01-1d.txt
+```
+
+Purpose:
+
+- test whether the panel only cares about the "live" pages, not the quiet ones
+
+#### HE37d: reversed odd-only cycle
+
+```powershell
+python scripts/serial_sequence_probe.py --port COM5 --prompt --prompt-screen --pre-read 2.0 --frame "00 00 1D 20 D0 B7" --frame "00 00 1B 20 D0 B1" --frame "00 00 19 20 D0 B3" --frame "00 00 17 20 D0 BD" --frame "00 00 15 20 D0 BF" --frame "00 00 13 20 D0 B9" --frame "00 00 11 20 D0 BB" --frame "00 00 0D 20 D0 A7" --frame "00 00 0B 20 D0 A1" --frame "00 00 09 20 D0 A3" --frame "00 00 07 20 D0 AD" --frame "00 00 05 20 D0 AF" --frame "00 00 03 20 D0 A9" --frame "00 00 01 20 D0 AB" --repeat 4 --frame-interval 0.35 --read-after-frame 0.15 --read-after-group 1.0 --log captures/he37-reversed-odd-01-1d.txt
+```
+
+Purpose:
+
+- same family membership, opposite order
+- if order matters, this should behave worse than `HE37c`
+
+#### HE37e: `0x40`-family-focused ordered run
+
+Known `0x40`-leaning branch selectors:
+
+- `0x00`, `0x01`, `0x05`, `0x09`, `0x0D`, `0x11`, `0x15`, `0x19`, `0x1D`
+
+```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 05 20 D0 AF" --frame "00 00 09 20 D0 A3" --frame "00 00 0D 20 D0 A7" --frame "00 00 11 20 D0 BB" --frame "00 00 15 20 D0 BF" --frame "00 00 19 20 D0 B3" --frame "00 00 1D 20 D0 B7" --repeat 5 --frame-interval 0.40 --read-after-frame 0.15 --read-after-group 1.0 --log captures/he37-ordered-40family.txt
+```
+
+Purpose:
+
+- see whether one specific subfamily behaves most like a maintained status page
+
+#### HE37f: `0x20/0x10`-family-focused ordered run
+
+Known non-`0x40` selectors:
+
+- `0x02`, `0x03`, `0x07`, `0x0B`, `0x13`, `0x17`, `0x1B`
+
+```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" --frame "00 00 07 20 D0 AD" --frame "00 00 0B 20 D0 A1" --frame "00 00 13 20 D0 B9" --frame "00 00 17 20 D0 BD" --frame "00 00 1B 20 D0 B1" --repeat 5 --frame-interval 0.40 --read-after-frame 0.15 --read-after-group 1.0 --log captures/he37-ordered-20-10-family.txt
+```
+
+Purpose:
+
+- test whether the non-`0x40` siblings are the real ordered data pages
+
+#### HE37g: hold-then-step ladder
+
+This is the most "old broadcast gear" test in the set: hold one page long enough
+for the panel to latch it, then step to the next.
+
+```powershell
+python scripts/serial_sequence_probe.py --port COM5 --prompt --prompt-screen --pre-read 2.0 --frame "00 00 01 20 D0 AB" --frame "00 00 01 20 D0 AB" --frame "00 00 01 20 D0 AB" --frame "00 00 03 20 D0 A9" --frame "00 00 03 20 D0 A9" --frame "00 00 05 20 D0 AF" --frame "00 00 05 20 D0 AF" --frame "00 00 09 20 D0 A3" --repeat 4 --frame-interval 0.50 --read-after-frame 0.20 --read-after-group 1.2 --log captures/he37-hold-then-step.txt
+```
+
+Purpose:
+
+- test whether later pages only "count" after earlier pages have been presented
+  for a while
+
+#### Recommended order
+
+1. `HE37a` ordered ascending `0x00-0x0F`
+2. `HE37b` shuffled control
+3. `HE37c` ordered odd-only
+4. `HE37d` reversed odd-only
+5. `HE37e` `0x40`-family run
+6. `HE37f` `0x20/0x10`-family run
+7. `HE37g` hold-then-step
+
+Interpretation guide:
+
+- if ordered beats shuffled, sequence matters
+- if ascending odd-only beats reversed odd-only, order matters even more strongly
+- if one family-only run behaves best, we may have identified the maintained
+  "camera state page" class
+- if hold-then-step behaves best, the panel may be sampling pages in sequence
+  rather than merely checking for their existence
+
+### HE37 Result: Ordered-Cycle Hypothesis
+
+Capture files present:
+
+- `captures/he37-ordered-00-0f.txt`
+- `captures/he37-shuffled-00-0f.txt`
+- `captures/he37-ordered-odd-01-1d.txt`
+- `captures/he37-reversed-odd-01-1d.txt`
+- `captures/he37-ordered-40family.txt`
+- `captures/he37-ordered-20-10-family.txt`
+- `captures/he37-hold-then-step.txt`
+
+Panel-side observation:
+
+- the full ascending `0x00-0x0F` run reportedly only held the panel clear for
+  the first group, then lost it
+- the other HE37 runs reportedly held the panel in its clear/non-
+  `CONNECT NOT ACT` state for the length of the run
+- none produced a visible wake-up beyond the normal/default panel state
+
+#### Big picture
+
+The "1990s ordered scan" idea was a good hypothesis, but these results do not
+show a strong "correct order unlocks the panel" effect.
+
+What they do suggest is a subtler model:
+
+- **which frame family is present** matters
+- **keeping to a tighter active subset** helps
+- but **strict ordering by itself** does not appear to wake the panel
+
+#### HE37a vs HE37b: ordered ascending vs shuffled `0x00-0x0F`
+
+Result:
+
+- both runs only produced the same familiar early group-1 branch behavior
+- after that, both settled into heartbeat-compatible traffic
+- no richer serial progression appeared in the ordered run
+
+Read:
+
+- using the same low-band pages in ascending order did **not** beat the same
+  pages shuffled
+
+#### HE37c vs HE37d: ordered odd-only vs reversed odd-only
+
+Result:
+
+- both odd-only runs behaved similarly
+- both held the panel clearer than the full `0x00-0x0F` pass
+- neither showed a decisive serial advantage for ascending vs reversed order
+
+Read:
+
+- trimming the cycle to the "live" odd-command subset helps more than the exact
+  direction of the scan
+
+#### HE37e: ordered `0x40`-family run
+
+Result:
+
+- group 1 still opened the familiar `0x40` branch around:
+  - `07 80 40 24 DD 64`
+- later groups stayed heartbeat-compatible
+- panel reportedly stayed clear for the duration
+
+Read:
+
+- the `0x40`-family subset is a plausible maintained background class
+- but it still does not look like the missing full wake/session stream
+
+#### HE37f: ordered `0x20/0x10`-family run
+
+Result:
+
+- group 1 still opened the familiar `0x20 0x12` branch around:
+  - `07 80 20 12 97 78`
+- later groups stayed heartbeat-compatible
+- panel reportedly also stayed clear for the duration
+
+Read:
+
+- the non-`0x40` active subset also behaves like a viable maintained background
+  class
+- again, no evidence yet that it is the unique "correct next page sequence"
+
+#### HE37g: hold-then-step
+
+Result:
+
+- this run did complete and is valid
+- it produced the same basic early one-shot `0x40`-family behavior in group 1
+- then settled into heartbeat-compatible traffic
+
+Read:
+
+- holding a page longer before stepping did **not** unlock a richer progression
+
+Current best interpretation after HE37:
+
+- we still do **not** have evidence for one exact required page order
+- we **do** have evidence that narrower active subsets maintain the panel better
+  than a broad "everything from `0x00` upward" scan
+- the panel may care more about:
+  - being fed the right **class** of recurring pages
+  - at a believable cadence
+  - than about one strict ascending sequence
+
+That means the next most 1990s-looking hypothesis is probably:
+
+- a **small recurring scan set** for the maintained background layer
+- plus some separate startup/beacon/identity pages
+- rather than one giant ordered status loop by itself
+
+### HE38: Broad Semi-Awake State Hunter
+
+Goal: broaden outward from the known `20 D0` low-command surface and look for
+other command regions that keep the panel in the same clear / semi-awake state,
+even if they do not fully wake it.
+
+This is intentionally a **state-hunting** pass, not just an anomaly-hunting one.
+The useful observations are:
+
+- whether the LCD stays clear / non-`CONNECT NOT ACT`
+- whether a run only holds that state for group 1, or for the whole script
+- whether any new structured families appear
+
+#### HE38a: broaden low-band sweep `0x20-0x3F @ 20 D0`
+
+```powershell
+python scripts/serial_direct_response_sweep.py --port COM5 --prefix1s 0x00 --prefix2s 0x00 --commands 0x20-0x3F --states 0x20 --values 0xD0 --settle 3.0 --after-each 0.8 --after 2.0 --pause-on-anomaly --log captures/he38-direct-20d0-cmd20-3f.txt
+```
+
+Purpose:
+
+- check whether the semi-awake surface extends past `0x1F`
+- keep the same state/value pair that has worked best so far
+
+#### HE38b: broaden low-band sweep `0x40-0x5F @ 20 D0`
+
+```powershell
+python scripts/serial_direct_response_sweep.py --port COM5 --prefix1s 0x00 --prefix2s 0x00 --commands 0x40-0x5F --states 0x20 --values 0xD0 --settle 3.0 --after-each 0.8 --after 2.0 --pause-on-anomaly --log captures/he38-direct-20d0-cmd40-5f.txt
+```
+
+Purpose:
+
+- look for a second semi-awake band elsewhere in command space
+
+#### HE38c: baseline control `0x20-0x3F @ 00 80`
+
+```powershell
+python scripts/serial_direct_response_sweep.py --port COM5 --prefix1s 0x00 --prefix2s 0x00 --commands 0x20-0x3F --states 0x00 --values 0x80 --settle 3.0 --after-each 0.8 --after 2.0 --pause-on-anomaly --log captures/he38-direct-0080-cmd20-3f-control.txt
+```
+
+Purpose:
+
+- compare the same command region under the older baseline payload
+- separate "command region effect" from "`20 D0` payload effect"
+
+#### HE38d: alternate promising payload `0x20-0x3F @ 40 30`
+
+```powershell
+python scripts/serial_direct_response_sweep.py --port COM5 --prefix1s 0x00 --prefix2s 0x00 --commands 0x20-0x3F --states 0x40 --values 0x30 --settle 3.0 --after-each 0.8 --after 2.0 --pause-on-anomaly --log captures/he38-direct-4030-cmd20-3f.txt
+```
+
+Purpose:
+
+- test whether this "holds panel clear" effect is unique to `20 D0`
+- `40 30` is the other payload pair most worth cross-checking here
+
+#### HE38e: semi-awake candidate repeat check
+
+If any HE38 sweep appears to hold the panel clear for most of the run, repeat
+just the first good-looking candidate frame on its own:
+
+```powershell
+python scripts/serial_probe_response.py --port COM5 --tx-frame "<candidate frame>" --repeat 30 --interval 0.60 --delay 3 --after 3 --frame-size 0 --log captures/he38-repeat-<candidate>.txt
+```
+
+Use this only for candidates that look good both:
+
+- serially, and
+- on the LCD/panel state
+
+#### Recommended order
+
+1. `HE38a` `0x20-0x3F @ 20 D0`
+2. `HE38c` baseline control `0x20-0x3F @ 00 80`
+3. `HE38b` `0x40-0x5F @ 20 D0`
+4. `HE38d` `0x20-0x3F @ 40 30`
+5. `HE38e` repeat any good-looking candidates
+
+Interpretation guide:
+
+- if `20 D0` keeps finding wider semi-awake bands while `00 80` does not, then
+  the payload pair is doing real mode/session work
+- if `0x20-0x3F` behaves like `0x00-0x1F`, then we are looking at a much larger
+  maintained surface than we first thought
+- if only a few sparse candidates hold the panel clear, then the maintained
+  background layer may be a selected subset rather than a continuous command map
+
+### HE38 Result: No-Pause Semi-Awake Hunting
+
+Additional uninterrupted capture files present:
+
+- `captures/he38-direct-20d0-cmd20-3f-nopause.txt`
+- `captures/he38-direct-0080-cmd20-3f-control-nopause.txt`
+- `captures/he38-direct-20d0-cmd40-5f-nopause.txt`
+
+Panel-side observation:
+
+- these uninterrupted reruns were stopped manually at roughly the point where
+  the panel lost its "alive"/clear state
+
+That means these runs are useful primarily as **semi-awake duration probes**, not
+as complete command maps.
+
+#### `0x20-0x3F @ 20 D0`
+
+Observed before manual stop:
+
+- `0x21` -> `07 80 48 24 DD 6C`
+
+Read:
+
+- the patterned `20 D0` surface definitely extends upward into the `0x20` band
+- this is consistent with the earlier low-band `4x 24 DD 6x` family structure
+
+#### `0x20-0x3F @ 00 80` control
+
+Observed before manual stop:
+
+- `0x29` -> `07 80 4A 20 D8 6F`
+
+Read:
+
+- the same command region is still live under baseline `00 80`
+- but the family shape stays on the older `20 D8` style rather than the newer
+  `24 DD` style
+
+#### `0x40-0x5F @ 20 D0`
+
+Observed before manual stop:
+
+- `0x41` -> `07 80 50 24 DD 74`
+- `0x42` -> repeated `07 80 50 24 DD 74`
+- `0x43` -> `07 80 50 24 DD 74`
+
+Read:
+
+- this is the strongest new semi-awake lead from HE38
+- the `0x40` command band under `20 D0` appears to open a neighboring
+  `0x50 24 DD 74` family
+- and it did so early enough in the run to matter before manual stop
+
+Current best interpretation after HE38:
+
+- `20 D0` remains the more interesting semi-awake payload
+- not because baseline `00 80` is dead, but because `20 D0` keeps shifting the
+  family surface into coherent `24 DD`-style siblings
+- the semi-awake-maintenance surface is now plausibly broader than just the
+  original low band:
+  - `0x00-0x1F`
+  - `0x20-0x3F`
+  - and likely at least part of `0x40-0x5F`
+
+The best next narrow branch is now:
+
+- treat `0x41-0x43 @ 20 D0` as a new maintained-background candidate set
+- and compare that `0x50 24 DD 74` behavior against the earlier `0x40 24 DD 64`
+  / `0x48 24 DD 6C` bands
+
+### HE38 Cross-Check: What The Paused Runs Still Taught Us
+
+The paused HE38 runs are not the right source for "how long did the panel stay
+alive?", but they were still very useful for **family mapping**.
+
+#### `0x20-0x3F @ 20 D0` family structure
+
+The paused run shows a very clean patterned surface:
+
+- `0x21` -> `07 80 48 24 DD 6C`
+- `0x25` -> `07 80 49 24 DD 6D`
+- `0x29` -> `07 80 4A 24 DD 6E`
+- `0x2D` -> `07 80 4B 24 DD 6F`
+- `0x31` -> `07 80 4C 24 DD 68`
+- `0x35` -> `07 80 4D 24 DD 69`
+- `0x39` -> `07 80 4E 24 DD 6A`
+- `0x3D` -> `07 80 4F 24 DD 6B`
+
+Interleaved sibling families also appear:
+
+- `0x23` -> `07 80 24 12 97 7C`
+- `0x2B` -> `07 80 25 12 17 FD`
+- `0x33` -> `07 80 26 12 97 7E`
+- `0x3B` -> `07 80 27 12 17 FF`
+- `0x27` -> `07 80 12 09 D7 11`
+- `0x37` -> `07 80 13 09 D7 10`
+
+So this is not just "some activity in the `0x20` band"; it is a strongly
+ordered mapped surface.
+
+#### `0x40-0x5F @ 20 D0` family structure
+
+The paused run also maps a second coherent band:
+
+- `0x41` -> `07 80 50 24 DD 74`
+- `0x45` -> `07 80 51 24 DD 75`
+- `0x49` -> `07 80 52 24 DD 76`
+- `0x4D` -> `07 80 53 24 DD 77`
+- `0x59` -> `07 80 56 24 DD 72`
+- `0x5D` -> `07 80 57 24 DD 73`
+
+That is the strongest evidence yet that the `.. 24 DD ..` surface spans
+multiple command bands, not just the original low region.
+
+#### `0x20-0x3F @ 00 80` control structure
+
+The baseline payload maps the same general region, but with the older family
+style:
+
+- `0x29` -> `07 80 4A 20 D8 6F`
+- `0x2D` -> `07 80 4B 20 D8 6E`
+- `0x31` -> `07 80 4C 20 D8 69`
+- `0x35` -> `07 80 4D 20 D8 68`
+- `0x39` -> `07 80 4E 20 D8 6B`
+- `0x3D` -> `07 80 4F 20 D8 6A`
+
+with interleaved siblings like:
+
+- `0x33` -> `07 80 26 10 2C C7`
+- `0x3B` -> `07 80 27 10 2C C6`
+
+That reinforces the idea that `20 D0` is not inventing a new command region
+from scratch; it is shifting an existing mapped surface into a different family
+space.
+
+#### `0x20-0x3F @ 40 30` alternate-payload structure
+
+The `40 30` paused run gives a third aligned surface:
+
+- `0x21` -> `07 80 48 28 D3 6E`
+- `0x25` -> `07 80 49 28 D3 6F`
+- `0x29` -> `07 80 4A 28 D3 6C`
+- `0x2D` -> `07 80 4B 28 D3 6D`
+- `0x31` -> `07 80 4C 28 D3 6A`
+- `0x35` -> `07 80 4D 28 D3 6B`
+- `0x39` -> `07 80 4E 28 D3 68`
+- `0x3D` -> `07 80 4F 28 D3 69`
+
+with matching interleaved families:
+
+- `0x23` -> `07 80 24 14 4A A7`
+- `0x2B` -> `07 80 25 14 0A E6`
+- `0x33` -> `07 80 26 14 CA 25`
+- `0x3B` -> `07 80 27 14 8A 64`
+- `0x27` -> `07 80 12 0A 6A AF`
+- `0x37` -> `07 80 13 0A EA 2E`
+
+Current read after including the paused runs:
+
+- the command surface is looking increasingly like a **mapped lattice**
+- the command byte selects a row/slot
+- the host payload pair (`00 80`, `20 D0`, `40 30`) shifts the response family
+  across parallel surfaces
+- so the "semi-awake" question is probably about which of these surfaces is the
+  right maintained background class, not about whether the map exists at all

    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`
+  - `0x03` -> `07 80 20 12 97 78`
+- 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:
+    - `0x05` -> `07 80 41 24 DD 65`
+    - `0x09` -> `07 80 42 24 DD 66`
+    - `0x0D` -> `07 80 43 24 DD 67`
+    - `0x11` -> `07 80 44 24 DD 60`
+    - `0x15` -> `07 80 45 24 DD 61`
+    - `0x19` -> `07 80 46 24 DD 62`
+    - `0x1D` -> `07 80 47 24 DD 63`
+    - interleaved siblings also appear in `0x10 0x09 D7 ..` and
+      `0x20 0x12 .. ..` families
+- So `20 D0` now looks like a broader low-command maintained surface, not just
+  a four-command curiosity.
+- A later ordered-cycle test pass (`HE37`) did **not** show strong evidence
+  that one exact ascending page order wakes the panel.
+- What it did suggest instead:
+  - broad low-band scans are a bit fragile
+  - narrower active subsets hold the panel clearer more reliably
+  - both the `0x40`-leaning subset and the `0x20/0x10`-leaning subset can act
+    like maintained background traffic
+- So the current "1990s Sony" model is less "one magic page order" and more:
+  - startup/beacon pages
+  - then a small recurring maintained scan set
+  - then additional camera-state detail pages we still have not identified
+- A later no-pause HE38 pass broadened the same idea:
+  - `0x21 @ 20 D0` -> `07 80 48 24 DD 6C`
+  - `0x41-0x43 @ 20 D0` -> `07 80 50 24 DD 74`
+  - while the baseline control in the same `0x20-0x3F` region stayed on the
+    older `20 D8` style (`07 80 4A 20 D8 6F`)
+- That suggests `20 D0` is not just shifting one command or one small pocket;
+  it may be selecting a broader `.. 24 DD ..` maintained-background surface
+  across multiple command bands.
+- The paused HE38 runs strengthened that structure further:
+  - `0x20-0x3F @ 20 D0` maps cleanly through `48/49/4A/.../4F 24 DD`
+  - `0x20-0x3F @ 00 80` maps the same area through `4A/4B/4C/.../4F 20 D8`
+  - `0x20-0x3F @ 40 30` maps it again through `48/49/4A/.../4F 28 D3`
+- So the best current model is a parallel set of response surfaces selected in
+  part by the host payload pair, with the remaining question being which surface
+  behaves like the true maintained background layer for an active panel.
