The backfill route shared the analytics-read bucket and sent every
explicit range without a key, so one account could queue two-year
backfills until the instance-wide daily budget was gone for everyone.
The route now allows three backfills a rolling hour per account (429
environment.backfill_rate_limited) and one queued backfill per
twenty-minute slot, keyed on the account (409
environment.backfill_pending). Every fetch made for an account is also
charged to that account's own share of the daily budget, one twentieth
of it, so a refused request ends the run as budget-blocked and the
nightly run continues.
A location period whose sealed location this host cannot open was
dropped from the resolver, so its days fell through to the home and the
next refresh overwrote the stored travel days with the weather at home.
Those days are now skipped and the run logs an error signal.
A restore now opens every sealed location once. One that does not open
is kept sealed, so the refresh keeps skipping its days, and is named in
the restore report under a new catalogue.
Fetch the Open-Meteo air-quality feed (CAMS, domains=auto) with the weather:
17 hourly variables folded into local days by fixed rules (means and maxima
only with 18 of 24 hours, ozone as the highest 8-hour running mean, UV only
with the midday hours), a value the feed did not cover stored as null, never
as zero. Requests are cut into 90-day chunks, newest first, and chunks before
mid 2022 ask for the eight pollutant and index variables only. An air-quality
failure never costs the weather row; the day stays unfetched and the nightly
gap fill (up to 90 days per account, newest first) asks for it again.
Every Open-Meteo request asks an instance-wide budget kept in Postgres first
(500 a minute, 4000 an hour, 8000 a day, weighted by the hosted pricing
rule). A refused request is not sent and the run ends as done with
budget_blocked. OPENMETEO_AIR_QUALITY_URL and ENVIRONMENT_AIR_QUALITY_DISABLED
are honoured; the account switch lives on PATCH /api/environment/preferences.
The home, each dated location period and each stored day keep their coarse
location sealed as one value under healthlog/environment-location/v1. The
writers write the sealed value only, the readers open it and fall back to the
readable columns for rows the free-text encryption backfill has not reached,
and the backfill now seals all three and clears the readable columns. The
backup carries the location readable in a portable file and sealed in a
disaster-recovery file; a restore seals either under the receiving key.
Three correlation channels join the environment family (PM2.5, the ozone
8-hour high, the day's highest pollen count), read through the averaged
same-day window and left empty while air quality is off. The Coach and MCP
gain get_environment: module-gated, clamped to the lookback limit, no
coordinate or place name anywhere, with provenance and the attribution
lines. The settings section gets the switch, the coverage and the newest
day's values; the dashboard shows a quiet chip on a day with high pollen,
a warm night or very poor air. Copernicus and Open-Meteo are credited next
to the values.
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.
Land every file the v1.42 work shares before any of it is built, so the
parts built side by side never edit the same file.
Schema and migrations 0379-0386: the HEALTH_CONNECT measurement source,
ImportJob.kind, the air-quality columns and the per-user switch on the
environment tables, sealed environment locations with nullable plaintext,
managed-profile handover links, the per-type HealthKit arrival ledger, lab
unit-conversion provenance, and user-defined vaccines. Every new column is
annotated for the column-reader sweep.
HEALTH_CONNECT reaches every exhaustive list: the source labels, the
read enum (not the write allowlist), the source-priority ladder cap, now
the number of sources rather than a fixed eight, and the write-path smoke
test. RMSSD gets its own priority class and a 300 ms ceiling. The batch
syncTrigger gains `manual`, with its label on the Apple Health card.
Queues for the Health Connect import, the compaction-tombstone purge and
the measurement-table maintenance are registered with stub handlers;
host-metric sampling moves to every five minutes. Environment and work_mem
variables reach the compose whitelist, the production example and the
manifest. The proxy admits the handover link and redirects it at the edge,
and the Health Connect upload bypasses the proxy body limit.
The new routes answer 501 behind their final authentication and are
published in the contract; backup, wipe and key rotation classify the new
models and columns; the seven message bundles carry the base copy. Guards
that list release-pending keys and columns fail once an entry is wired, so
those lists empty themselves before the tag.
Also re-anchor a login-throttle fixture to the wall clock, where its
expiry is compared, and re-base the aggregate bundle cap on a measured
12 KB of new locale strings.
`instant.toISOString().slice(0, 10)` and parsing a key back as UTC
midnight are the idioms behind every day-boundary fix this year: the
evening west of UTC and the small hours east of it land on the
neighbouring day. A new rule, healthlog/no-utc-day-key, refuses them in
src/ outside src/lib/tz and tests, and refuses a disable directive for
itself that is not next-line or gives no reason.
The time zone module now names every legitimate form: userDayKey for a
person's day, dateOnlyKey / dateOnlyAtNoonUtc / dayKeyAsUtcMidnight for
date-only values and day labels, daysBetweenDateKeys / weekdayOfDateKey /
isCalendarDateKey / statedDateKey for key arithmetic and parsing.
Of the 133 sites the rule found, 84 are gone. Most moved onto a named
helper with no change in behaviour; these changed behaviour:
- cycle calendar, insights, Coach snapshot and prediction refresh start
their lookbacks at the first instant of the user's day
- a model-transcribed date like "June 10, 2026" no longer lands a day
early in a process east of UTC (documents and lab scans)
- a custom report range covers exactly the picked days in the profile
zone instead of starting the evening before west of UTC
- date-of-birth pickers cap at the user's today, not the UTC one
- an allergy onset date is stored at noon UTC like other date-only values
- the report's cycle summary, the Coach's usual BP range and the intake
projector's rollup recompute use the user's day
- vaccination dates render as dates instead of the previous evening
49 remain, each with its reason on the line above: 39 UTC by design (15
file name stamps, rollup and object keys, the UTC-day score engines) and
10 marked baseline. A guard test requires a classified reason on every
directive and holds the baseline to a ceiling that only goes down.
The home location of the environment module was rounded to 2 decimals,
about 1 km, which places a home in a neighbourhood rather than the town the
schema comment promised. The weather archive it feeds is gridded at 9 to
25 km, so the extra precision bought nothing.
Every stored coordinate of the module now goes through the same 1-decimal
rounding (about 11 km north-south, 7 km east-west at 50° N): the home, the
travel periods, the geocoder's results, the per-day weather rows, and a
restore of a file written with finer values. Migration 0361 rounds the
existing users, travel periods and per-day rows; running it twice changes
nothing more. The answers keep their shape, plain numbers. The API
descriptions and the schema comment say 1 decimal now.
docker-compose.yml forwards its whitelist as "${NAME:-}", so a variable
the operator never set reaches the process as the empty string. Reads
written as a nullish fallback kept that string: the weather client built
an empty base URL and every geocode failed with ERR_INVALID_URL, and the
IP geo lookup requested a relative path.
Reads with a fallback now go through src/lib/env.ts (envValue, envOr,
envFlag), which treats empty and whitespace as unset. IP_GEO_LOOKUP_DISABLED
accepts 1, true, yes and on instead of only "1". A structural test refuses
a ?? fallback written directly against process.env anywhere in src/, and
the compose whitelist guard counts the helper's call shape as a read.
The correlation-narrative localisation replaced the env-channel narration
labels (which read through getEnvironmentField().narrationLabel) with the
localised insights.correlation.channel.ENV_* keys, leaving these two helpers
dead.
The nightly discovery fan-out called isModuleEnabled per candidate user —
N serial DB reads on a large instance. Resolve the opt-in gate in-memory
from one findMany plus a single operator-availability read instead. The
per-day backfill upserts ran one awaited statement at a time (up to 730
for a full backfill); batch each location group's upserts into a single
transaction round-trip while keeping the idempotent semantics.
Rework the per-day location resolution so it can no longer fabricate weather for
days before the home was set. Precedence, first hit wins:
1. an explicit dated location period (a trip, or a corrected stretch of
history) covering the day;
2. DEVICE — a reserved slot for a future client-supplied coarse per-day
location (ranks between the period and home; not produced server-side yet);
3. the home location, but only for days on/after its effective-from date;
4. otherwise the day is skipped.
The home route stamps `homeSince` whenever the home is set/updated and returns
it. The overview exposes it. Backfill bounds are now optional and default to the
conservative `[homeSince .. today]` span instead of a fixed reach onto the
current home; days before `homeSince` still resolve to a skip in the worker, so
even a wider explicit start cannot back-fill weather for the pre-home past. To
reach further back a user adds an explicit location period for that range.
Add unit coverage for the precedence (including the effective-from boundary and
the skip-not-guess rule) and the default backfill range.
Add the keyless Open-Meteo client (historical archive + geocoding) routed
through safeFetch, the per-day location-resolution + fetch/upsert service
(travel override wins over home, then degrades silently), and the shared
environmental-exposure field table the registry and correlation engine both
read. The base URL is operator-overridable for a self-hosted instance; the
fetch stays server-side so a private/LAN host is not blocked.
