+## HE29 Host-Fed Branches
+
+The HE29 fan-out did not visibly wake the panel, but it did produce two new
+structured RCP families when certain **host-shaped family/status frames** were
+sent directly:
+
+| Host stimulus | RCP result | Read |
+| --- | --- | --- |
+| `00 00 7A 50 26 56` | `07 80 2F 95 C9 AE` | direct family-feed branch; meaningful but one-shot |
+| `00 00 40 40 30 6A` | `07 80 D0 50 26 7B` | base-status-family branch; meaningful but one-shot |
+
+What this suggests:
+
+- not every interesting family is only a passive response/readback block
+- some host-origin family-shaped frames can still stimulate deeper structured
+  responses
+- but even these branches did **not** create a stable active session or visible
+  panel wake-up
+
+So, on the state map, these look like:
+
+- additional **host-fed branch entries**
+- not yet evidence of the missing full conversation/session ladder
+
+## HE30 Family Surfaces
+
+HE30 suggests those HE29 host-fed branches are not isolated one-offs. They now
+look like two small **parameterized surfaces**:
+
+| Host-side family | Observed RCP-side family variants | Read |
+| --- | --- | --- |
+| `7A ...` | `2F 95 C9`, `2F 65 F2`, `2F 95 52` | likely a host-fed `7A` -> `2F` mapping surface |
+| `40/50 ...` | `50 78 26`, `50 50 26`, `50 58 26`, `D4 50 26` | likely a host-fed base-status mapping surface |
+
+Examples:
+
+- `00 00 7A 50 26 56` -> `07 80 2F 95 C9 AE`
+- `00 00 7A 58 26 5E` -> `07 80 2F 65 F2 65`
+- `00 00 7A 50 3A 4A` -> `07 80 2F 95 52 35`
+- `00 00 40 40 30 6A` -> `07 80 50 78 26 D3` or `07 80 50 50 26 FB`
+- `00 00 50 40 30 7A` -> `07 80 D4 50 26 7F`
+- `00 00 40 60 30 4A` -> `07 80 50 58 26 F3`
+
+What this means on the map:
+
+- some host-fed families are acting like **query/page selectors** into deeper
+  response spaces
+- those spaces are still one-shot and context-sensitive
+- and they still do not by themselves imply a stable active session
