+### HE39: Narrow In On The `0x50 24 DD 74` Band
+
+Working idea: the `0x40-0x5F @ 20 D0` region may be a stronger maintained
+background class than the earlier low-band `0x40 24 DD 64` region.
+
+Known lead so far:
+
+- `0x41 @ 20 D0` -> `07 80 50 24 DD 74`
+- paused run also showed:
+  - `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`
+
+Goal: see whether this band:
+
+- holds the panel clear longer,
+- behaves better as a maintained subset,
+- or opens anything richer than the earlier `0x40 24 DD 64` surface.
+
+#### HE39a: repeat only `0x41 @ 20 D0`
+
+Target frame:
+
+- `00 00 41 20 D0 EB`
+
+```powershell
+python scripts/serial_probe_response.py --port COM5 --tx-frame "00 00 41 20 D0 EB" --repeat 30 --interval 0.60 --delay 3 --after 3 --frame-size 0 --log captures/he39-repeat-cmd41-20d0.txt
+```
+
+#### HE39b: repeat only `0x45 @ 20 D0`
+
+Target frame:
+
+- `00 00 45 20 D0 EF`
+
+```powershell
+python scripts/serial_probe_response.py --port COM5 --tx-frame "00 00 45 20 D0 EF" --repeat 30 --interval 0.60 --delay 3 --after 3 --frame-size 0 --log captures/he39-repeat-cmd45-20d0.txt
+```
+
+#### HE39c: repeat only `0x49 @ 20 D0`
+
+Target frame:
+
+- `00 00 49 20 D0 E3`
+
+```powershell
+python scripts/serial_probe_response.py --port COM5 --tx-frame "00 00 49 20 D0 E3" --repeat 30 --interval 0.60 --delay 3 --after 3 --frame-size 0 --log captures/he39-repeat-cmd49-20d0.txt
+```
+
+#### HE39d: small `0x50`-band mixer
+
+```powershell
+python scripts/serial_sequence_probe.py --port COM5 --prompt --prompt-screen --pre-read 2.0 --frame "00 00 41 20 D0 EB" --frame "00 00 45 20 D0 EF" --frame "00 00 49 20 D0 E3" --repeat 10 --frame-interval 0.60 --read-after-frame 0.20 --read-after-group 0.80 --log captures/he39-mixer-41-45-49-20d0.txt
+```
+
+#### HE39e: wide `0x50`-band mixer
+
+```powershell
+python scripts/serial_sequence_probe.py --port COM5 --prompt --prompt-screen --pre-read 2.0 --frame "00 00 41 20 D0 EB" --frame "00 00 45 20 D0 EF" --frame "00 00 49 20 D0 E3" --frame "00 00 4D 20 D0 E7" --frame "00 00 59 20 D0 F3" --frame "00 00 5D 20 D0 F7" --repeat 6 --frame-interval 0.60 --read-after-frame 0.20 --read-after-group 1.0 --log captures/he39-mixer-50band-wide-20d0.txt
+```
+
+#### HE39f: control repeat from the older low-band lead
+
+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 30 --interval 0.60 --delay 3 --after 3 --frame-size 0 --log captures/he39-repeat-cmd01-20d0-control.txt
+```
+
+#### Recommended order
+
+1. `HE39a` repeat `0x41`
+2. `HE39f` control repeat `0x01`
+3. `HE39b` repeat `0x45`
+4. `HE39c` repeat `0x49`
+5. `HE39d` small `41/45/49` mixer
+6. `HE39e` wide `0x50`-band mixer
+
+Interpretation guide:
+
+- if `0x41/0x45/0x49` hold the panel clear longer than `0x01`, the `0x50` band
+  is probably a better maintained-background candidate
+- if the mixer behaves better than any one frame, that supports a small
+  recurring in-family scan model
+- if everything behaves the same as `0x01`, then this is probably just another
+  parallel mapped surface, not a privileged wake-adjacent one
+
+#### HE39 results
+
+Observed panel behavior across all HE39 runs:
+
+- all runs kept the panel in the clear / semi-awake state for the duration of
+  the script
+- none produced a fuller wake-up beyond that state
+
+Single-frame repeat results:
+
+- `HE39a` repeating `00 00 41 20 D0 EB`:
+  - first send: heartbeat only
+  - second send: opens `07 80 50 24 DD 74`
+  - several copies of that family then drain out
+  - later repeats stay heartbeat-only
+- `HE39b` repeating `00 00 45 20 D0 EF`:
+  - first send: heartbeat only
+  - second send: opens `07 80 51 24 DD 75`
+  - then returns to heartbeat-only behavior
+- `HE39c` repeating `00 00 49 20 D0 E3`:
+  - first send: heartbeat only
+  - second send: opens `07 80 52 24 DD 76`
+  - several copies drain out, then heartbeat only
+- `HE39f` control repeating `00 00 01 20 D0 AB`:
+  - same overall pattern as before
+  - second send opens `07 80 40 24 DD 64`
+  - later repeats are heartbeat-only
+
+Mixer results:
+
+- `HE39d` small `41/45/49` mixer:
+  - group 1 only:
+    - `0x41`: no RX
+    - `0x45`: opens `07 80 51 24 DD 75`
+    - `0x49`: drains more `07 80 51 24 DD 75`
+  - later groups are heartbeat-compatible only
+- `HE39e` wide `41/45/49/4D/59/5D` mixer:
+  - same practical pattern as the small mixer
+  - group 1 opens on `0x45` into `07 80 51 24 DD 75`
+  - later `0x49/4D/59/5D` frames do not open additional stages
+  - later groups are heartbeat-compatible only
+
+Takeaways:
+
+- the `0x50`-band is real and coherent:
+  - `0x41` -> `07 80 50 24 DD 74`
+  - `0x45` -> `07 80 51 24 DD 75`
+  - `0x49` -> `07 80 52 24 DD 76`
+- but it behaves serially just like the older low-band `0x40 24 DD 64` lead:
+  - an early one-shot family burst
+  - then flat heartbeat-compatible maintenance
+- so the "keeps the panel alive" effect is broader than one specific command
+  slot inside the `20 D0` surface
+- the mixers did not outperform the simpler repeats
+- current best read: this is another maintained-background surface, not yet a
+  privileged wake-up band
