naming officerdev/chat in layout.ts rendered a second Hosts panel. the shared
registry is not the thing that decides: PluginScreen renders the workspace with
appTypes={{ allowed, fallback: allowed[0] }} where allowed is THIS plugin's own
panel keys, so an unrecognised appType silently becomes the first panel. that
boundary is deliberate — its comment says a persisted layout must not be able
to render another plugin's panel inside this screen — and it is a different
mechanism from seedAppRegistry merging the panels, which is what the last
commit's reasoning confused it with.
so the panel is ours and EmbeddableChat inside it is the platform's. it is
exported from officerdev for exactly this: the whole composer, transcript,
queue and model picker, with no second implementation to fall behind the
first.
it carries a two-sentence promptPrefix, which is per-panel and costs nobody
else's conversation anything. deliberately short: the skill holds the
knowledge and reaches every session for two lines, so anything longer here
would be the skill written twice and this would be the stale copy. all it says
is where the agent is standing, which is the one thing the skill cannot know.
