Three pieces of code answered "what hour is it" for the salutation. The snapshot builder computed a `greetingHour` in the user's zone and put it on the payload so clients would not have to; no client ever read it. The insights hero derived one through the shared `hourInTz`. The dashboard header derived one through a local helper that fell back to the DEVICE clock whenever the runtime could not resolve the configured zone, which is what happens to an IANA entry the browser's data does not yet carry. At one instant, for one account, those three returned 20, 21 and 05. Keep the client end and drop the server one. The hour is a clock reading, not a fact about the record, and the snapshot body serves stale for up to an hour past its fresh TTL, so a stored hour can name a salutation the clock has left behind. What the server IS authoritative for is the zone, and that already travels on the same payload and is already what both surfaces read. Both greetings now share `hourInTz`, so an unresolvable zone falls back to the same default the rest of the app uses instead of to the device. The header's private helper is gone; it had no other caller. Two tests pinned the old shape by asserting the payload carried an hour. Inverted rather than deleted: the payload must now be shown NOT to carry one, which is the property that was missing when the field went unread for months. `greetingHour` leaves the response contract, so a native client decoding it as required needs the field made optional or dropped.
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.
