Marc-André Bombeck bec4cb3dfb fix(mcp): let five of the six shipped languages name a metric
Three resolvers turned a user-authored word into an internal code by
comparing it against a hand-typed English list. The app ships six
languages, so five of them resolved nothing: `Fer` and `Żelazo` came back
as `unknown_nutrient` while the settings card rendered exactly those
words, and `poids` and `sommeil` reached no series at all.

Stop transcribing. `nutrients.names.*` and `measurements.type*` already
label these concepts in every bundle, so the match index is derived from
`locales` instead — a seventh language works the day its bundle lands,
with no edit at any call site. The nutrient tool's English labels now come
out of `messages/en.json` too, so the wire wording cannot drift from the
screen.

The MCP contract is unchanged in shape and stays protocol-level English.
What moves is which words are understood: `unknown_nutrient` /
`unknown_metric` still mean "could not place this word", distinct from a
placed name answering `no_data`. Nothing turns absence into data.

Two findings the sweep did not predict:

- `Puls` resolved to pulse-wave velocity, because the English
  display-name pass matches substrings and "pulse-wave velocity" contains
  it. An exact name now beats a loose English fragment.
- French and Italian use one phrase for body fat and fat mass, and three
  bundles use one for fat-free mass and lean body mass. A word two
  metrics claim resolves to neither; answering kilograms to someone who
  asked for a percentage is worse than saying the word was not
  recognised. The known set is pinned so a new collision surfaces.

The medication needles are the exception: they are drug names, with no
bundle to derive from. They fold to a normalised INN stem rather than to
a language, so `Metformin`, `Metformine`, `Metformina` and `Metforminum`
are one entry, and `Semaglutyd` and `Atorwastatyna` cost nothing to add.
A guard asserts no two molecules collapse onto one stem. Iron is the one
class with no stem to fold to — it is named for the element — so its word
list is hand-tabulated and says so.

Every English resolution that worked before returns the same answer.

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/ — 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 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/ — 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.
