`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.
A grant has meant one thing since it shipped: the whole record, to read or to
add to. This lays the words for the two shapes the rest of the sharing work
needs — part of a record, and management of one — while changing what no
existing grant does.
`ShareDomain` is a closed set of eight sections in `src/lib/sharing/scope.ts`,
clustered from the delegable read surfaces rather than invented, plus the
distinguished `record` for the routes that read across them. It never converts
to a `ModuleKey` and never imports one: two masks, two questions, no shared
spelling, because the day they share a name is the day somebody makes one
imply the other, and a module the owner enabled is not a section the owner
shared.
`account_grants.scope_json` is NULL on every row that exists, and NULL is the
entire record — the answer those rows were consented as, so no backfill and no
re-consent. A non-NULL value is read through one fail-closed normaliser: a
blob it cannot parse opens nothing, including a section the blob happened to
name. That is the deliberate inverse of the module preference normaliser,
which fails open on purpose; both do the safe thing with a value nobody can
read, and the safe thing differs because one answers an authorization question
and the other a presentation question.
`MANAGE` joins the level enum, ordered above WRITE so a write grant can never
satisfy it, and carries no scope at all: management of part of a record
promises a boundary that cannot survive an edit, so the invite path refuses to
write one.
`requireRecordAuth` takes the section as a second required argument. The
requirement is the lever — a delegable route without a classification does not
typecheck, so the set of classified routes cannot fall behind the set of
delegable ones. All fifty-seven modules carry theirs. The structural guard
freezes each against the production vocabulary, fails when a module's own arms
disagree, and pins a non-zero count of resolved sections so a matcher that
stopped reading the argument fails instead of agreeing with everything.
`requireGuardianAuth` is exported and reaches nothing yet. It gates on the
managed-profile marker rather than on the grant, so an adult who granted
management of their own record cannot arrive at that record's settings by any
argument about what MANAGE means: widening MANAGE would widen the record
resolver and would not touch this one. Its frozen list lands empty, with the
declaration site as the positive control that keeps "nothing reaches it" a
measurement rather than a renamed symbol.
`users.managed_profile_at` says since when a record is one somebody else runs.
A timestamp and not a boolean, for a reason the schema has to keep possible:
clearing it is the handover, and the grants and the activity trail span it
untouched.
Eight routes: the two sleep reads, the nutrient overview and its daily
series, the illness episode list, detail and day logs, and the workout list.
The illness day-log read is the one worth reading twice. Its queries are
episode-scoped rather than user-scoped, and what makes them safe is the
`loadOwnedEpisode(id, user.id)` hop above them. That hop now resolves against
the record, so a delegate cannot reach their own episode from inside somebody
else's account — asserted, because it is the kind of thing that would look
fine and behave wrong.
`GET /api/workouts/[id]` stays refused. It differs from the list beside it by
one conditional include that decrypts a paragraph written about the owner.
A device can write the same period twice: an original envelope and a
corrected one, same start, later end, distinct external ids. Both rows
belong to the same writer, so the writer collapse keeps both, and the
per-stage totals added them. One night served a 10 h 13 min in-bed
headline next to a 20 h 17 min in-bed legend on the same screen, and
the hypnogram drew the night twice over.
Every per-stage total is now the measure of the union of that stage's
spans rather than the sum of the rows, and the same merged spans feed
the hypnogram segments and the time-asleep headline. Stages merge
independently: two stages describing one minute is a contest, and the
writer collapse is this file's mechanism for that - arbitrating again
would collapse the summary-shaped writers, which stamp every stage
total on the sleep end instant and nest by design.
stages.IN_BED is now the in-bed envelope itself, the same union
inBedMinutes reports, so the legend cannot contradict the headline and
a night whose envelope only a losing writer recorded still reports it.
Three surfaces where the words no longer matched the code, plus the missing
web control for a preference the server already honours.
Delete confirmations. Four dialogs promised permanence on surfaces that
render an Undo: the measurements and mood bulk bodies, the lab-result body,
and the illness-episode body (which said "cannot be undone" sixty lines
below the code that fires the Undo toast). All four now use the same
sentence the single-row measurement and mood dialogs already used. A sweep
of every other confirmation in the tree found the rest accurate — the
biomarker cascade, the mood-tag purge, and the account purge keep their
warning because those deletes really are unrecoverable.
Sleep debt. v1.19.0 replaced the summed shortfall with a running balance
that credits catch-up sleep; the labels still described the old sum, so the
word contradicted the number for anyone who slept in after a short night.
Corrected in all six locales, plus the places the old semantics had
propagated: the Coach system prompt, the OpenAPI field descriptions the
native client reads, and four module docblocks.
Glucose reference band. `hasDiabetes` selects the tighter reference band and
grounds the Coach, but no web surface set it — a web-only account was pinned
to the non-diabetic scale with no way out. The control goes on Targets,
above the per-metric editor, because it answers the same question that page
answers and the two are ordered: it picks the default band, an override
below beats it. The copy says what it is — a reference band, not a
diagnosis, never inferred from a reading, no clinical action taken on it.
The passkey list was reported as always reading "never used". It does not
reproduce: the column is selected by the list route and stamped on every
verified assertion, both since v1.23.0. Pinned with tests on both halves so
the contract cannot quietly regress.
A one-time background pass re-reads each connected account's Google Health
sleep history so nights stored twice before the sleep fix collapse to their
true total (new sleep_repaired_at marker, migration 0238; watermark-safe,
enqueued once at boot per un-repaired connection).
The sleep night read reports when two writers disagree about the same night —
the served total is unchanged, the disagreement rides along as an annotation
(sourceDiscrepancy on the night DTO) so clients can mark the number instead of
silently picking a side.
A GLP-1 medication whose weight has plateaued on the current dose says so next
to the estimated drug level (efficacy tab + insights) — a factual note from the
existing detector, association only, verb-guard covered.
Google Health diagnostics: the sync log now separates a daily-totals read that
returned nothing from one the importer could not parse
(googleHealth.rollup.emptyResponse vs droppedAll), and the connection test's
structure probe reports the raw response envelope key names when a rollup type
parses to zero — a per-account naming drift becomes visible from one report.
The canonical rotation registry (src/lib/crypto/encrypted-columns.ts) is the
source of truth its guard test cross-checks; add EcgRecording.waveformEncrypted
there (the script already references it) and drop the redundant parallel guard.
Update the sleep/rhythm route test to the v1.19.0 rolling 5-night balance
(nightsCounted 5, debt 300) instead of the old 14-night cumulative sum.
One-shot prettier pass so the new format:check gate starts from a clean
baseline. Formatting only — no behaviour change. Generator-owned and
vendored artifacts stay untouched via .prettierignore.
Walk every per-domain route tree that serves a toggleable module and
classify each route.ts as module-gated, delegated (cycle/coach),
builder-gated (doctor-report/FHIR), or explicitly exempt with a reason.
A new ungated module route trips the guard by name.
Close four route-level gate gaps the inventory surfaced: the mood
analysis reads (/api/mood/insights, /api/mood/analytics) and the sleep
view reads (/api/sleep/night, /api/sleep/rhythm) now gate on their
module instead of staying reachable over a Bearer token while the module
is off. Pin the gate to enabled in the three pre-existing route suites.
WHOOP's v2 API returns only per-stage sleep duration totals — no onset
timestamps, no hypnogram endpoint. The mapper stamped all five stage
totals on the one sleep-END instant, so the hypnogram reconstructed
every stage as a span touching the night's right edge: bars stacked
right-aligned with no clock times whenever WHOOP was the sole source.
Lay the asleep stages back-to-back from sleep onset in a fixed
physiological order (AWAKE lead, then CORE → DEEP → REM), emitting one
timed row per segment with measuredAt at that segment's end and a
distinct indexed externalId. IN_BED stays a single envelope row over the
whole window. The existing reader and renderer are untouched — they now
see distinct per-segment instants and place each block at its own time.
The order is synthesised, not measured, so every reconstructed row is
flagged and the night DTO carries a per-session `reconstructed` boolean
(GET /api/sleep/night, regenerated OpenAPI). The client renders the
hypnogram but labels it an approximate layout and never recomputes;
real-series sources (Apple Health, Withings, Fitbit) stay false.
Compute cumulative sleep debt and the MCTQ chronotype server-side off the
canonical night reconstruction the Sleep Score reads, and render them on
the sleep page: a sleep-debt headline with a calm partial state under the
night threshold, and a chronotype card whose social-jetlag detail and
corrected mid-sleep sit behind an advanced disclosure. Both hold a learning
state on thin data and never assert a total or a band.
Serve the same values to the dashboard summary and a new GET /api/sleep/rhythm
read so the native client renders identical figures. Free vs work nights
default to weekend in the user's timezone until day-type tracking exists.
Replace the divergent UTC-day night reconstructor in the Sleep Score with a
thin adapter over reconstructSleepNights, the shared engine the dashboard,
hypnogram, and doctor surfaces already read. The old path bucketed rows by UTC
calendar day and never deduplicated writers, so a multi-source night (WHOOP +
Apple Health for the same sleep) summed both writers and roughly doubled the
total. The adapter inherits session-clustering, local-wake-day keying, and
multi-source writer dedup, then derives the score-only fields the canonical
night does not carry: REM and Deep minutes from the stage map, the stage-
breakdown flag from any granular stage, and the midpoint from the asleep span.
Select source and deviceType in the Sleep Score read so the writer-dedup
ladder fires, and thread the user source priority through so the chosen writer
matches every other sleep surface. Round emitted asleep and in-bed minutes to
whole numbers, and round the per-stage map in the sleep-night DTO, matching the
integer contract the native client decodes.
A multi-source user's sleep score and the readiness score that folds it drop
once the double-count is removed, reflecting the true single-writer night.
`GET /api/sleep/night` summed second-precision stage rows into asleep /
awake totals and serialised them unrounded (e.g. 433.4999), which also
violated the OpenAPI integer contract. Round the present minute values;
`inBedMinutes` / `awakeMinutes` stay null when the night never saw that
stage.
Sleep nights collapse per writer instead of per source: several
HealthKit apps land behind the same source value, so a phone's coarse
awake and in-bed blocks could blend into or fully constitute a night
whose stages another writer had recorded. The winning writer per
session is the one with the most distinct granular stages, then the
user's source ladder, and its rows are kept whole. The device type is
threaded through every sleep read including the stage stacked bar, and
the sync overlap for late-arriving nights widens from one day to seven
so a night scored after the cursor passed is fetched on the next tick —
assembly is read-time, so affected nights heal without manual repair.
Mood notes expand to their full text in the list on desktop and touch,
replacing the hover-only tooltip, and the mood CSV export carries a
note column.
The client bundle carries only the active locale — resolved on the
server and handed to the provider with no hydration flash, halving the
dashboard route to under a megabyte parsed (288 KiB gzip). The auth
shell renders the app chrome immediately instead of a spinner while the
session resolves in parallel, the widgets request folds into the
snapshot it duplicated, and insight pills prefetch their sub-pages —
a first visit to a sub-page lands in about ninety milliseconds instead
of nearly a second.
GET /api/sleep/night?date=YYYY-MM-DD returns one reconstructed night for
the phase-progression view: the canonical source's stage segments (each
with an absolute start/end span), the per-stage breakdown, the asleep/
in-bed/awake totals, the mid-sleep awakenings count, and same-wake-day
naps surfaced separately. Session-clustered, wake-day-keyed, one
canonical source per night so two sources never overlay. date omitted
returns the most recent night. A view over existing per-stage rows — no
schema, no new measurement type. OpenAPI regenerated.
