Fetch the Open-Meteo air-quality feed (CAMS, domains=auto) with the weather: 17 hourly variables folded into local days by fixed rules (means and maxima only with 18 of 24 hours, ozone as the highest 8-hour running mean, UV only with the midday hours), a value the feed did not cover stored as null, never as zero. Requests are cut into 90-day chunks, newest first, and chunks before mid 2022 ask for the eight pollutant and index variables only. An air-quality failure never costs the weather row; the day stays unfetched and the nightly gap fill (up to 90 days per account, newest first) asks for it again. Every Open-Meteo request asks an instance-wide budget kept in Postgres first (500 a minute, 4000 an hour, 8000 a day, weighted by the hosted pricing rule). A refused request is not sent and the run ends as done with budget_blocked. OPENMETEO_AIR_QUALITY_URL and ENVIRONMENT_AIR_QUALITY_DISABLED are honoured; the account switch lives on PATCH /api/environment/preferences. The home, each dated location period and each stored day keep their coarse location sealed as one value under healthlog/environment-location/v1. The writers write the sealed value only, the readers open it and fall back to the readable columns for rows the free-text encryption backfill has not reached, and the backfill now seals all three and clears the readable columns. The backup carries the location readable in a portable file and sealed in a disaster-recovery file; a restore seals either under the receiving key. Three correlation channels join the environment family (PM2.5, the ozone 8-hour high, the day's highest pollen count), read through the averaged same-day window and left empty while air quality is off. The Coach and MCP gain get_environment: module-gated, clamped to the lookback limit, no coordinate or place name anywhere, with provenance and the attribution lines. The settings section gets the switch, the coverage and the newest day's values; the dashboard shows a quiet chip on a day with high pollen, a warm night or very poor air. Copernicus and Open-Meteo are credited next to the values.
docs/ — internal reference + operator playbooks
The user-facing documentation lives at https://docs.healthlog.dev — that's the canonical surface for self-hosting guides, integration walkthroughs, AI-provider setup, and the doctor-report workflow.
The files in this directory are the internal operator playbooks, audit notes, and machine-readable specs that ship alongside the source:
api/— the OpenAPI 3.1 spec for the native-client subset (iOS DTO codegen target). Seeapi/README.mdfor the preview commands. Also home to the MCP-server contract:api/mcp-capabilities.md(tools, resources, prompts, write model) andapi/mcp-skills.md(building a connector / skill).ops/— operator runbooks: deploy, backup / restore, encryption-key rotation, password reset and account recovery, env checks, TLS pinning, data repair. These are what an operator reaches for during an incident.self-hosting/— horizontal-scaling notes (HEALTHLOG_PROCESS_TYPE=web|worker|all) and the deploy-pipeline recipe. Routine install steps stay ondocs.healthlog.dev. Includesself-hosting/mcp.md— enabling the off-by-default MCP connector and pointing Claude.ai / ChatGPT / Claude Desktop at it, andself-hosting/sso.md— OIDC SSO login: IdP setup, the identity-pinning security model,OIDC_ONLYconsequences, and the break-glass runbook. Alsoself-hosting/geolite2.md— bringing your own offline GeoLite2 databases viaGEOLITE2_DIRinstead of sending login IPs to a third-party lookup. Andself-hosting/account-sharing.md— letting one account on the instance open another's health record: the three access levels, the eight sections a grant can be narrowed to, managed profiles for somebody with no login and the guardians who look after them, what revocation does and does not undo, and which trust properties of the instance are unchanged by any of it.migration/— migration notes. Currently only v1.3 to v1.4; later releases are covered byCHANGELOG.mdand https://docs.healthlog.dev.integrations/— per-integration reference (Withings, Fitbit, Google Health, WHOOP, Apple Health, AI providers, data import).adr/— architecture decision records.security/— threat-model notes.diagrams/— architecture diagrams rendered through docs.healthlog.dev.releases/— release imagery.apple-store-connect-checklist.md— the iOS submission gate.codex-protocol-spec.md— Codex / ChatGPT OAuth protocol reverse-engineering notes.ui-guidelines.md— UI / a11y house style.
