spike(harness): probe gate behavior in pi --mode rpc + findings
Static analysis of Pi runtime (rpc-mode.js, agent-session.js, runner.js)
confirms all 4 decisive questions:
- Q1 kickoff: NO — source:"rpc" bypasses the "interactive" guard (agent-session.js:720)
- Q2 widget emission: NO — ctx.sendRaw does not exist, crashes (0 refs in core/extensions/)
- Q3 response routing: NO — rpc-mode.js returns after consuming extension_ui_response;
pi.on("extension_ui_response") never fires (not in runner.js)
- Q4 steering: YES — steer() bypasses emitInput entirely
Decision: both Task 3 (kickoff guard) and Task 4 (emitAndWait → ctx.ui.* / Variant A)
require gate adaptation.
