+Observed results:
+
+| Test | Sequence | Observed response |
+| --- | --- | --- |
+| CS1 | `00 -> A0` | `07 80 E8 40 30 45` |
+| CS1 | `00 -> B8` | `07 80 6E 40 30 C3` |
+| CS1 | `00 -> BC` | `07 80 6F 40 30 C2` |
+| CS2 | `9F -> A0` | heartbeat only |
+| CS2 | `B7 -> B8` | `07 80 6E 40 30 C3` |

+| Single-frame control | `B8` | heartbeat only |
+| Single-frame control | `BC` | heartbeat only |
+
+Important comparison against earlier sweeps:
+
+| Selected query | Earlier primer sweep response | New `00 -> query` response |
+| ---: | --- | --- |
+| `A0` | `07 80 68 40 30 C5` | `07 80 E8 40 30 45` |
+| `B8` | `07 80 EE 40 30 43` | `07 80 6E 40 30 C3` |
+| `BC` | `07 80 EF 40 30 42` | `07 80 6F 40 30 C2` |
+
+Interpretation:
+
+- Single `A0`, `B8`, and `BC` frames after boot produced heartbeat only, so
+  these responses require prior host traffic.
+- The response is not determined only by the selected query command. The same
+  selected query can produce different response blocks in different setup
+  contexts.
+- `B7 -> B8` and `BB -> BC` reproduced the alternate `B8`/`BC` responses seen
+  in the paused direct sweep.
+- `90 -> 9F -> A0` reproduced the earlier `A0` response
+  `07 80 68 40 30 C5`, while `9F -> A0` alone produced no response.
+- `00 -> A0` now produced the alternate `A0` response
+  `07 80 E8 40 30 45`, so the `00` first frame is not always a simple
+  deterministic "generic primer" in the current bench state.
+- The evidence now favors a stateful/page-sensitive discovery model rather than
+  a single fixed primer model.
+
+Working model after these datasets:
+
+```text
+Host sends one or more setup/selector frames.
+RCP arms one readable response.
+The next selected query returns a block from the currently selected page/state.
+After that response, the RCP latches until power cycle or an unknown reset/state
+advance command.
+```
+
+Recommended next confirmation:
+
+1. Repeat `00 -> A0`, `00 -> B8`, and `00 -> BC` once more after clean power
+   cycles to see whether the alternate page is now stable.
+2. Repeat `90 -> 9F -> A0` once more to confirm the earlier page can be selected
+   reliably.
+3. Test whether `90 -> A0` alone selects the earlier page, or whether `9F` is
+   also required.
+4. Test whether `00 -> 9F -> A0` behaves like `90 -> 9F -> A0`, which would
+   suggest `9F` is the real selector and `90` is only a setup/arming frame.
