Alex sees a blank particle field form in real time as she answers 5 phases of questions. Each answer immediately updates the seeding animation. At Phase 5, particles converge into her unique resting pattern. Agent says: "This is what your stress looks like. I will watch it with you."

The particle field warms from teal to orange-yellow. Density rises. Oscillating clusters form. The AgentTopPanel pill shifts from "Watching" to "Pending." The agent detects stress_score crossing the recipe threshold — but sees a meeting in progress and holds the intervention.

Particles contract into a tight, fast-spinning amber-red vortex. The StressOrb brightens and pulses. SmartWatch mirrors the acute biometric state on the wrist. Agent state stays "pending" — calendar shows the meeting runs until 14:40. The system waits rather than interrupting.

5 minutes after block_end, agent fires buildQuery() using Alex's live profile: stress_archetype=tension, recovery_style=alone, audio_preference=[rain, white_noise], location=office. Apify calls run server-side. InterventionCard appears as a bottom sheet with synthesized results — not raw lists.

Alex accepts the breathing guide. The recipe engine begins sequencing: breathing guide starts immediately, then lighting shifts (warm → cool), then the diffuser activates. Each step fires at its delay_ms offset. The particle field begins cooling — density -20%, hue shifts toward teal over 8 seconds. Anticipation: particles contract inward 0.3s before the transition.

contextInference detects home. Recipe engine matches "Rain & Lavender" recipe to home_evening trigger. YouTube Actor fetches "rain white noise ASMR sleep 1 hour" — personalized with Alex's audio_preference and chronotype:evening. Amazon Actor fetches "lavender muscle relaxation magnesium fast acting supplement." Particle field begins cooling.

HRV rises above the 10% threshold. Particle size grows, velocity slows. Particles settle into slow orbit via spring physics — overshoot and settle. RecoveryGlow fires: a radial pulse emanates from the canvas center. efficacy_history entry is written: hrv_delta=+12, stress_before=61, stress_after=34. Recipe efficacy_score updates. Next YouTube query will weight "rain" higher.

Particles reach minimum density — sparse soft violet, slow galaxy-like orbits. Full recipe executed: particle_state snaps to Recovered. Galaxy pattern convergence animation plays: particles sweep sequentially from outer to inner. A soft resonance sound fires. Timeline view shows the full day arc. Sleep guide begins. efficacy_score averaged across history.
