    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.
+- A tighter HE39 pass on the `0x50`-band showed:
+  - `0x41 @ 20 D0` -> `07 80 50 24 DD 74`
+  - `0x45 @ 20 D0` -> `07 80 51 24 DD 75`
+  - `0x49 @ 20 D0` -> `07 80 52 24 DD 76`
+  - all of those can keep the panel in the clear / semi-awake state while the
+    script is active
+  - but serially they still behave as one-shot branch openings followed by
+    heartbeat-compatible maintenance, not as a richer multi-turn wake sequence
+- So the `0x50`-band currently looks like another valid maintained-background
+  surface inside the broader `20 D0` class, not yet a uniquely privileged
+  "real wake" surface.
+- A later HE40 completion pass extended that picture much farther upward:
+  - `0x61 @ 20 D0` -> `07 80 58 24 DD 7C`
+  - `0x81 @ 20 D0` -> `07 80 60 24 DD 44`
+  - `0xC1 @ 20 D0` -> `07 80 70 24 DD 54`
+  - `0xE1 @ 20 D0` -> `07 80 78 24 DD 5C`
+- That means the `20 D0` surface now looks like a broad upper command lattice,
+  not just a low-band or mid-band pocket.
+- HE40 also reinforced that `40 30` is a true aligned parallel surface:
+  - `0x01 @ 40 30` -> `07 80 40 28 D3 66`
+  - `0x41 @ 40 30` -> `07 80 50 28 D3 76`
+  - `0x61 @ 40 30` -> `07 80 58 28 D3 7E`
+- Small prefix-completion sweeps on `cmd=0x21 @ 20 D0` showed that nonzero
+  prefixes are not inert:
+  - `p2=0x01` opened `07 40 24 12 9D B6`
+  - `p1=0x01` opened `07 80 48 24 9D 2C`
+- So prefixes probably do **not** define the main lattice by themselves, but
+  they can perturb a known-live slot into variant families.

+## Probable CCU <-> RCP Traffic Model
+
+This is an inferred working model, not yet a proof. It is the best current
+attempt to explain both the manuals and the bench behavior using the same
+mental picture.
+
+### High-level picture
+
+Current best read:
+
+- the **CCU** probably holds the richer master state for the camera system
+- the **RCP** behaves more like a smart terminal:
+  - it sends operator events upstream
+  - it receives recurring camera/session state downstream
+  - it renders that state onto the LCD, lamps, and numeric readouts
+
+That would fit:
+
+- the manuals describing filter, extender, self-diagnosis, and other camera
+  state on the RCP display
+- the broad structured lattices now observed in the host-to-RCP direction
+- the way repeated valid-looking traffic can keep the panel semi-awake without
+  fully activating it
+
+### Likely traffic layers
+
+#### 1. Startup / identity / mode layer
+
+Probable job:
+
+- establish PT2/TX7 personality
+- announce CCU or camera-side mode/class
+- select a broad session context before live status traffic begins
+
+Best candidate families so far:
+
+- `90` startup-beacon surface:
+  - `07 80 64 40 30 C9`
+  - `07 80 E4 40 30 49`
+- `AF` startup-beacon surface:
+  - `07 80 0D 04 AB 7F`
+  - `07 80 0D 04 EB 3F`
+- `A0` appears to act as an opener or primer in several selector contexts
+
+Current interpretation:
+
+- these look more like startup or class beacons than maintained live camera
+  state by themselves
+
+#### 2. Maintained background status layer
+
+Probable job:
+
+- keep the panel in a live or semi-live session state
+- refresh recurring camera/control pages
+- provide the "boring background scan" a 1990s CCU would likely send
+
+Best candidate surfaces so far:
+
+- `20 D0` lattice:
+  - `0x01 -> 07 80 40 24 DD 64`
+  - `0x21 -> 07 80 48 24 DD 6C`
+  - `0x41 -> 07 80 50 24 DD 74`
+  - `0x61 -> 07 80 58 24 DD 7C`
+  - `0x81 -> 07 80 60 24 DD 44`
+  - `0xC1 -> 07 80 70 24 DD 54`
+  - `0xE1 -> 07 80 78 24 DD 5C`
+- parallel `40 30` lattice:
+  - `0x01 -> 07 80 40 28 D3 66`
+  - `0x41 -> 07 80 50 28 D3 76`
+  - `0x61 -> 07 80 58 28 D3 7E`
+- baseline `00 80` lattice:
+  - similar command slots but through `.. 20 D8 ..` surfaces
+
+Current interpretation:
+
+- these look like page/slot/status surfaces more than isolated commands
+- a real CCU may repeatedly scan a small subset of these, not the whole space
+- the panel's semi-awake behavior strongly suggests that at least part of this
+  layer is real maintained traffic
+
+#### 3. Detail / page / selector layer
+
+Probable job:
+
+- select which family or page of data is being discussed
+- open branches corresponding to different camera/status domains
+
+Best candidate families so far:
+
+- `E8`, `E9`, `EC` selector-like branches
+- opener/context family around `A0`, `90`, `AF`
+- downstream siblings:
+  - `7A`
+  - `7B`
+  - `FB`
+  - `FA`
+  - `E4`
+
+Current interpretation:
+
+- these may represent internal page classes or selector families
+- they probably help choose *which* maintained or readable surface is live
+- they do not yet look like the final always-on camera-state stream by
+  themselves
+
+#### 4. Operator event layer
+
+Probable job:
+
+- carry human actions from the RCP to the CCU/camera side
+
+Best candidate families so far:
+
+- CALL path:
+  - host synthetic high/low pair can provoke `07 80 45 20 D0 68`
+- CAM POWER and some other buttons:
+  - visible as outbound panel-origin activity
+  - but not yet shown to wake the panel or advance a session on their own
+
+Current interpretation:
+
+- this layer is probably mostly upstream: RCP telling the CCU what the operator
+  just did
+- the event path alone is not enough to create an active session
+
+### Most likely division of responsibility
+
+If this model is right, then:
+
+- the **CCU** likely maintains the richer camera-state lattice internally
+- the **RCP** likely maintains a smaller local cache:
+  - current screen/page
+  - local control state
+  - most recently received camera values
+  - active indicator/lamp state
+
+That would explain why:
+
+- broad command sweeps find orderly families
+- many repeated frames keep the panel semi-awake
+- but the panel still refuses to fully wake without the right overall stream
+
+### What this suggests for bench work
+
+The main practical implication is:
+
+- stop thinking only in terms of a single hidden wake frame
+- keep thinking in terms of:
+  - startup beacon/context
+  - then a believable recurring maintained subset
+  - then additional detail pages layered on top
+
+So the most likely missing ingredient is not just "more valid bytes." It is
+probably a **specific recurring traffic mix** that a real CCU would send once
+it had already identified the panel and camera path.
