Ketones had to live in a custom metric, with the glucose-ketone index typed
in by hand beside it, where it drifted from the readings it came from.
- Type: BLOOD_KETONES (beta-hydroxybutyrate, mmol/L, migration 0496),
plausible from 0 to 10: the blood ketone meters read 0.0 to 8.0 and print
HI above it, and a venous value off a lab sheet fits under 10. Zero is a
real reading. No band, no direction, no personal record, off the Coach
snapshot and the correlations; readable over MCP and owned by the glucose
module like glucose.
- Entry: choosing blood ketones in the measurement form also takes the
glucose from the same fingerstick, in the account's glucose unit. Both
rows go through the array arm of POST /api/measurements with one
timestamp, so they land in one transaction or not at all.
- Index: glucose (mg/dL / 18.0182, the tree's one factor) over ketones,
computed at read time and never stored. Each ketone reading above zero
pairs with the glucose reading at the same instant, else the nearest one
within 15 minutes either side; a tie goes to the same source, then to the
earlier reading. Nothing pairs across a wider gap.
- Surfaces: GET /api/measurements/series takes kind=ketones and
kind=glucoseKetoneIndex (each point names the paired readings), and the
day carries glucoseKetoneIndex when both reading types are visible. The
new Ketones page charts the readings with the index beneath; the day view
shows the index beside the value tiles; the doctor report, its PDF and the
clinician share print it in the glucose group when both leaves are chosen,
since beside the ketones it gives the glucose back.
- FHIR: ketone readings export under LOINC 104816-4 (Beta hydroxybutyrate
[Moles/volume] in Blood). The index is left out: it has no LOINC term,
and both readings it is built from are in the bundle.
- The measurement form's action row moved into its own component to keep
the form inside its size budget.
OpenAPI regenerated; all ten locales; the import unit table lists the type.
HealthKit's basalEnergyBurned sat in the deferred set, so the batch route
refused it per entry and acceptedTypes left it out. It now maps to a new
BASAL_ENERGY_BURNED type in kcal (migration 0493), beside active energy
and never added to it.
It is cumulative like active energy: summed per day on the read path and
in the rollups, drained into one daily row, imported from export.zip,
listed and charted with its own label in every locale, part of the report
selection and the backup, and readable over MCP. It carries no personal
record direction and feeds no score, insight or Coach snapshot.
Health Connect is left unmapped on purpose: its basal metabolic rate is a
rate at one instant, not a day's energy. No other integration reports a
resting figure of its own.

Garmin Connect now offers a Personal API: a person creates a key for
their own account and any client can buy short-lived tokens with it.
HealthLog takes that key in a new Garmin card, checks it with Garmin
before storing it sealed on the user row, and polls every hour.
- Transport: key exchange with a per-process token cache keyed on the
key, one re-exchange on a refused token and then reauth_required, the
429 Retry-After carried to the caller, the China host tried when the
global one does not know the key, answers read with a byte cap, all
egress through safeFetch to the two fixed hosts.
- Sync: daily summaries, sleep summaries, HRV, weigh-ins and the
activity search, chunked to each resource's documented range, read one
after another and stopped at the first rate limit; today's menstrual
cycle summary adds logged period days the person has not logged.
- Backfill: a resumable walk through the shared admission lane that
learns where the history starts from the daily summaries and the
activities, waits out Garmin's rate limit and stamps its marker.
- Types: GARMIN source; BODY_BATTERY and STRESS_LEVEL for Garmin's own
day scores, kept apart from the computed STRESS_SCORE; TRAINING_READINESS
and ACUTE_TRAINING_LOAD for figures a bridge pushes through the ingest
token. All four chart on the recovery page and sit on the ladders,
units, ranges, labels and report groups like the device-native scores.
- Key expiry: learned from a token capped short of a day, else estimated
from the validity picked at connect; the card warns a week ahead and
asks for a new key once Garmin refuses the old one.
- Ledger, health, freshness, watchdog, backup classes, wipe plan,
encrypted-column registry, rotation script, OpenAPI and all ten
locales carry the new integration. The old "no Garmin connector" note
is gone.
Six Apple Health signals leave the deferred list and ride
POST /api/measurements/batch and the export.zip import end to end:
EXERCISE_MINUTES, STAND_MINUTES and STAND_HOURS (the exercise and stand
rings), MINDFUL_MINUTES, STATE_OF_MIND_VALENCE (iOS 18 State of Mind,
-1..1) and AFIB_BURDEN (AFib History, percent of the week). The ring
types and mindful minutes are cumulative, so the daily rollup is their
sum; AFib burden is scaled strictly from Apple's fraction and a value
above 1 is refused rather than guessed at. The archive import takes
mindful minutes from the session's dates and skips idle stand hours.
Every registry carries them: units, ranges, labels in all locales,
categories, chart tokens, report catalogue (mindful minutes and the
valence fenced as sensitive), signal registry with FHIR codings, and
MCP exposure for the three ring types only.
Workout GPS tracks are now an opt-in, off by default
(PATCH /api/auth/me/workout-routes, a switch on Data & Privacy). While
it is off, the workout batch route and the export import keep every
workout and drop its track with the same per-entry status. With it on,
the import reads the referenced GPX files from the archive one bounded
member at a time, thins each to the point cap and stores it sealed.
The climb a track carries is written to Workout.elevationM at write
time, so the workout insight no longer opens the track, and the AI
egress guard now freezes the set of files that read route geometry.
The derivation wrote an explicit off for every module the answers did not
name, which is right for a record being set up and wrong for one with years of
rows behind it. An established self-hoster has, for most modules, no stored
preference at all — they were default-on and nobody ever touched the toggle —
so the first confirm took away the navigation entry, the dashboard widget and
the settings entry for domains full of content. The rows survived; the
surfaces did not.
A derived off now asks first, and only for the modules it would actually
retract. Ownership is not re-answered: the measurement domains come from the
same map the MCP reads and the coach snapshot gates off, and each remaining
module names the one table its content lives in, exhaustively, so a module
added later fails to compile until somebody says where its content is. A
module whose domain holds rows keeps whatever the record already had, because
absence is what "on" looks like in the stored map.
One suite per gate: the rich reads omit with an honest module_disabled
reason, the correlations reader omits and touches no channel, the
doctor-visit resource and prompt refuse without assembling the record,
and the clinician share collapses to its documents-only state. Each
asserts the operator availability path alongside the user toggle, and
that the gate short-circuits before the engine runs rather than building
the answer and withholding it.
The structural test pins that every metric the rich reads can resolve has
either an owning module or a written review decision, and is explicit in
its own comment about what it cannot prove — it does not show that any
read calls the gate. Writing it surfaced an unowned HRV_RMSSD, the
fallback type an RMSSD-only account resolves to, which would have served
recovery data the primary type refuses.
The MCP surface reached three data families that deliberately bypass the
Coach snapshot and so inherited none of its module narrowing: the
doctor-report aggregate behind healthlog://report/doctor-visit and the
doctor_visit_summary prompt, the rollup-backed rich reads (compare_metric,
get_metric_baseline, detect_changepoints), and the correlations reader.
A disabled module — or one an operator switched off server-wide — still
egressed to a third-party assistant.
Gate at the read rather than per call site. The module-to-data ownership
table moves out of the Coach snapshot builder into
lib/modules/measurement-scope so every read gates off one map; the rich
reads resolve metrics through a module-aware resolver; the correlations
reader gates on insights itself, which also closes the same gap on the
Coach chat tool and the metric-page read strip.
Per-domain reads omit with an honest module_disabled reason; the
whole-record aggregate refuses, mirroring /api/export/health-record.
collectDoctorReportData gains a fail-closed backstop on its own module
key. The clinician share link, found while tracing the aggregate's
callers, had the same gap and now collapses to its documents-only state.
