+> make naowalk automatically scp the video server to the nao's home directory, and run, then terminate the video server on close
+
+Now I'll add a launcher class that deploys and runs `nao_video_server.py` over SSH, then wire it into startup/shutdown.
+
+Now update the `NaoTeleop.__init__` signature and wire in the deploy call before video/audio init:
+
+Now add teardown in the shutdown block:
+
+Now add the CLI flags and pass them through:
+
+Let’s update the `--media-relay` help text, since it currently implies the server must already be running manually:
+
+Now let's sanity-check the file compiles and the diff looks right:
+
+Diff looks clean. Now let's copy the finished file to outputs and present it.

+> lets gut the original audio and video code out, i want it all going through the relay, including my mic. Also lets see if we can improve the latency on the nao's mic audio
+
+Good, this stays unchanged (`start()`/`stop()` API preserved). Now let's check the HUD and shutdown/argparse sections:
+
+That's fine to leave as-is (harmless dead branch for "connecting"). Now the shutdown block and CLI/argparse section:
+
+Now let's do the bigger refactor. Starting with `nao_video_server.py` — adding the bidirectional talk channel and tightening audio buffering for latency:
+
+Given the scope of changes, I'll rewrite `nao_video_server.py` in full rather than patching piecemeal:
+
+Now let's do the equivalent large refactor on `naowalk.py`, section by section. First, the protocol constants and header comment:
+
+Now let's tune `SoundReceiver` for lower latency:
+
+Now update `feed()` to actively trim the backlog instead of just dropping one chunk on overflow:
+
+Now let's replace `LiveMicRelay` with the new `PushToTalk` class that talks over the media relay instead of SSH:
+
+Now I'll replace the entire `LiveMicRelay` class with `PushToTalk`:
+
+Now let's update `NaoTeleop.__init__` and the video/audio init methods:
+
+Now I'll replace this whole block with the simplified, relay-only version:
