Build the Apple-Health-Highlights grid of personal-vital tiles on the
Insights overview, backed by four new pure derived-metric compute
functions over the established seam:
- cardio-fitness band ("Fitness Age" frame) — VO2max placed against the
FRIEND-registry age/sex norm (Kaminsky 2015), surfaced + trended, never
re-derived.
- vascular-age delta — Withings vascular-age vs chronological age, a
relative wellness indicator (Vlachopoulos 2010 PWV framing), no medical
claim.
- HRV (SDNN) balance — reuses the typical-range engine for the band and
places the recent average as balanced / above / below; SDNN never
relabelled RMSSD; cadence-gated.
- BMI from weight + height — exact WHO classification, the fallback when
no device BMI exists.
Each metric carries coverage + confidence + provenance and cites its
standard through the provenance explainer. The dashboard renders one
SparklineDeltaTile per available vital: an absent vital does not render,
a still-building one shows the honest coverage meter rather than a
headline from too little history. Tiles read the generic
/api/insights/derived route through a TanStack Query hook keyed off the
centralised factory.
Regenerates the OpenAPI contract for the two new metric ids and adds the
vitals copy across all six locales.
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.ops/— backup / restore + encryption-key-rotation playbooks. These are the runbooks 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.migration/— release-by-release migration notes. Read the entry for the version you're upgrading from.audit/— per-release audit summaries archived for forensic traceability.apple-store-connect-checklist.md— the iOS submission gate.doctor-report.md— PDF generator design notes.codex-protocol-spec.md— Codex / ChatGPT OAuth protocol reverse-engineering notes.ui-guidelines.md— UI / a11y house style.
