Prediction Observation CPM Bundles

Goal

Telemetry is a research dataset. For this version, the app sends one self-contained prediction bundle after a successful prediction during an active monitoring session. The bundle keeps heart rate as summary data and sends only the CPM values used by predictions that include cpm40Avg.

Prediction Observation Telemetry Plan

The current canonical telemetry plan is:

Prediction Observation CPM Bundles

In short, telemetry queues one self-contained prediction bundle during an active monitoring session after a successful prediction. The bundle embeds the prediction observation and, when cpm40Avg is present, includes only the CPM values used by that prediction. Heart rate remains summary-only for this version.

GCP Server Deployment

HeatSafe Server Deployment on GCP

This document is the production runbook for the HeatSafe sync server.

Target shape

Cloud Run service for the API and dashboard
Cloud Run job for database migrations
Cloud SQL for PostgreSQL
Secret Manager for DATABASE_URL
Direct Cloud Run IAP for staff dashboard access

This keeps the first production version small. It avoids a load balancer unless the project later needs custom domains or multi-region routing.
