From d1f28666b084d9d5de324673a6a567c0c7271ac8 Mon Sep 17 00:00:00 2001 From: alvis Date: Mon, 11 May 2026 11:12:11 +0000 Subject: [PATCH] feat(integrations): add Google Health (Fit) integration with full permissions OAuth2 flow with all 11 Google Fitness scopes (activity, body, sleep, heart rate, nutrition, location, blood glucose/pressure/temperature, oxygen saturation, reproductive health). Stores access + refresh tokens; auto-refreshes on expiry. GoogleHealthSignalSource fetches steps, sleep sessions, active minutes, calories, and heart rate from the Fit aggregate + sessions APIs. Signals flow into both the tip orchestrator and the health-vitals pre-compute agent, which generates prompt snippets about step progress, sleep deficit, sedentary time, and elevated heart rate. Signal.kind extended with 'health'; IntegrationProvider extended with 'google-health'. Agent compute signal mapping enriched to include source, kind, and all features so health-vitals can filter its own signals.
