Demo: surface the streaming win with tighter Beat 2 timing - #13
Merged
Conversation
The streaming hot path landed `,,` at ~1.3s end-to-end on the fast
tier, down from ~5-10s. The previous demo still slept 9s during Beat
2 — the speed win was invisible.
Tightened:
Sleep 1500ms → 1200ms (between typo'd command and `,,`)
Sleep 800ms → 700ms (between `,,` and Enter)
Sleep 9s → 3500ms (display the diagnosis + dropped fix)
Sleep 3s → 2500ms (run the fix, show output)
Total demo length: 91.6s → 84.9s (-6.7s, -7%).
Added a comment block to Beat 2 explaining the streaming model —
the diagnosis and corrected command appear together once the model
emits the first complete {command, note} object plus a
non-Uncertain diagnosis. The 3.5s display window gives the audience
time to read both lines before the demo presses Enter.
No story changes; same beats, same fix outcome (./build.py prints).

Beat 2 now plays at roughly the rhythm a real user experiences: the diagnosis line lands on stderr and the corrected command lands on the prompt within ~1.3s of pressing Enter. The 3.5s display window leaves time for the audience to read both before the demo presses Enter again to run the fix.
