Marc-André Bombeck aca497d9ac fix(insights): correlate residuals, not the calendar
Two daily series that both follow the season (temperature and blood
pressure, daylight and sleep) correlated strongly with nothing between
them. In a seeded simulation of such a pair the engine surfaced a
finding in 58 % of 400-day runs and 30 % of 180-day runs, and a real
next-day effect under the season came back with the wrong sign.

Every daily pair now goes through seasonallyAdjustedPearson: a linear
trend and one annual harmonic are removed from both series (trend only
under 120 paired days), the residuals are correlated, and the p-value
uses the Pyper-Peterman effective sample size. Shrinkage and the
phrasing tier read the effective size too. BH-FDR and the effect floor
are unchanged. Pairs too short to fit the basis are not tested.

The weather channels are tested once over the mean of the day before
and the day itself against the same day's outcome (lagDays 0), which
pairs the overnight low with the night it shaped now that sleep is
keyed on the wake day. Discovered pairs carry an additive nEff, the
same-day templates are wired, and the matrix skips the weather read
when the environment module is off.

scripts/compare-correlation-findings.ts counts findings per account
before and after, read-only, for the release-candidate dry run.

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). See api/README.md for the preview commands. Also home to the MCP-server contract: api/mcp-capabilities.md (tools, resources, prompts, write model) and api/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 on docs.healthlog.dev. Includes self-hosting/mcp.md — enabling the off-by-default MCP connector and pointing Claude.ai / ChatGPT / Claude Desktop at it, and self-hosting/sso.md — OIDC SSO login: IdP setup, the identity-pinning security model, OIDC_ONLY consequences, and the break-glass runbook. Also self-hosting/geolite2.md — bringing your own offline GeoLite2 databases via GEOLITE2_DIR instead of sending login IPs to a third-party lookup. And self-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 by CHANGELOG.md and 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.
