The assertion in the module-gate suite could not fail: that fixture's mood
badges carry no completion date, so the result it drove had no pending
unlock and "nothing was written" was true either way. Restoring the INSERT
left it green.
The case moves to its own file with the builder faked so the result always
carries a pending unlock. Undoing the fix now turns it red. The
disabled-module invariant the old case reached for lives with the write, in
the sweep's suite.
A GET must not have side effects — api-handler.ts says so next to
READ_HTTP_METHODS, where an MCP-audience token is admitted on the safe
methods precisely because they are assumed to write nothing. Three routes
broke that: the sync handshake bumped User.lastSyncedAt, the achievements
read inserted unlock rows, and the cycle calendar fired a discarded promise
at the forecast cache so a failed write left no trace anywhere.
Each write moves to the place that causes it.
The sync checkpoint is now stamped by the batch ingest endpoints for
measurements, mood and intakes. The handshake reports it. That also fixes
the watermark: the checkpoint used to advance past a window the client had
not drained, and a client trusting it would skip that window. It can only
trail a real sync now.
The unlock rows move to a nightly achievement-unlock-sweep. The badge grid
never needed them — unlocked comes from the live metrics and the completion
date is derived — so the payload is unchanged; the rows pin that date and
carry it into the backup, and the sweep reaches accounts that never open
the page.
The cycle forecast moves to a nightly cycle-prediction-refresh. The
CyclePrediction row is not a cache of a read: it is the index the reminder
cron scans, so which reminders an account received depended on whether
somebody had opened the calendar. persistPredictionCache no longer
swallows its errors either — the job reports them.
POST /api/insights/ecg takes one recording per request: the stable
recording id the client already has, the on-device timestamp, the
sampling rate, the waveform as integer micro-volts, the lead, the
average heart rate, and the device's own verdict. Same gating as the
reads (auth, the insights module, the insightStatus surface), userId
from the session, APPLE_HEALTH the only source a client may claim.
sampleCount and durationSeconds are derived here, and nothing about the
waveform is ever interpreted.
The write body now lives in one place, src/lib/ecg/persist-recording.ts,
shared by the Withings sync, the export-archive importer and the new
route. Three writers with three persistence bodies is how the two ends
of one rule drift apart.
Migration 0291 adds the second unique index on
(user_id, source, recorded_at, sampling_frequency). The archive importer
identifies a strip by a hash of its content and a live client by the
device's own sample uuid, so the same physical recording arriving
through both doors carried two different ids and would have landed
twice. One device does not record two different strips at the same
instant at the same sampling rate, so the constraint is sound and the
convergence stops being a convention.
The table already holds rows on deployed instances and two writers have
been filling it since v1.19.0, so the index cannot just be created: a
pre-existing collision would abort the migration. The migration resolves
duplicates first, keeping the row with the most samples (a stored strip
beats a verdict-only row), then the one linked to its event
measurement, then the most recently written, then the lowest id so the
choice is total. The losers' event link is salvaged onto the keeper
first, so resolving a duplicate never costs the recording its place in
the event timeline.
If that resolution is wrong on some instance, the failure is visible at
deploy time and not later: db:migrate:deploy runs on boot, so the
container crash-loops with the migration named in the logs and the
release never serves traffic. A deploy that finishes in under thirty
seconds did not run it.
The GET list and detail routes and the export-archive path are
unchanged; this is a second door, not a replacement.
Two branches met here. One retired the fitness pillar and renamed the test's
pillar list accordingly; the other, written against the eight-pillar world,
referred to it by its old name and its old count. The merge kept the new
declaration and the old references, so nothing compiled.
The name carried the count, which is why the collision was visible at all.
There are seven now.
/api/auth/me/health-score-config shipped in v1.35.0 with a settings page
in front of it and no entry in the contract at all — no path, no schemas,
nothing. A client had the surface and no way to generate against it. This
is publication only; the route does what it already did.
Both verbs are registered off what the route actually returns rather than
off a neighbour's shape. The asymmetry matters and is now written down: the
request speaks the positive selection, the pillars that should count, while
the response carries both sides resolved plus the recipe version. The column
stores the complement, which is storage and no client's business.
The response's updatedAt is documented as optional because it genuinely is
absent until a selection exists — an account that never chose has nothing to
guard a write against, and a decoder that required the field would break on
that read.
The PATCH 422 is written out rather than reusing the shared base-token
response, because this route has four of them and a client branching on
meta.errorCode needs all four: the breadth refusal with the sentence to show
the person, the validation failure, the unparseable base token, and the
non-JSON body. Naming only the token would have been a contract that omits
the refusal people actually hit.
The route test now drives the real route to produce each of those responses
and asserts the published contract names every code that comes back, so a
response the route can emit but the spec does not describe fails the suite.
That closes the base-token ledger: nine routes emit invalid_base_updated_at
and all nine now document it.
GET /api/auth/passkeys was absent from the contract entirely — no path
entry, no schema — while the client teams had been pointed at a published
schema for it since v1.32.8. It is now registered with the shape the route
actually serves: id, name, credentialDeviceType, credentialBackedUp,
createdAt, and the nullable lastUsedAt that started this. The route itself
is unchanged; only the record of it was missing. PasskeyInfo is deliberately
separate from WebauthnMfaCredentialInfo — one lists sign-in credentials, the
other second-factor security keys, and merging them would blur two surfaces
that behave differently. The route test now compares the projection the
route asks Prisma for against the published property set, so neither end can
move without the other.
`invalid_base_updated_at` existed only in route tests. It is now on all
eight published endpoints that accept a `baseUpdatedAt` body token, and the
field description says the thing implementers keep getting wrong: an
unparseable token, `null` included, is rejected with 422 rather than falling
back to the unconditional write. Omitting the key is the only way to get
that write.
/api/auth/me/health-score-config also returns this 422 but is not in the
spec at all; publishing that route is a separate piece of work.
The `type` query parameter on GET /api/insights/derived carried the eleven
VITALS_BASELINE vitals and described itself as being for that metric only.
SAME_TIME_BASELINE takes a `type` too, and its four cumulative day metrics
were absent from the enum, so a client generated against the spec could not
send them at all. The parameter now publishes the union of both registry
sets and the description says which values belong to which metric. A guard
reads the enum back out of the assembled document and pins it to the
registry, so a type added to either engine reaches the contract with it.
The idempotency wrapper's two 409 arms sent `error` as `{ message }`. That
was the only object-shaped error the application emitted; every other route
sends the documented `{ data, error: <string> }` envelope, which is also
what the spec has always promised. The code was wrong, not the spec. Both
arms now build their response through one helper that sends the string, so
every route under withIdempotency serves the envelope its clients decode.
The hero score-ring comment still described MED_COMPLIANCE as pooled 7-day
adherence. It has been today's dose progress since v1.27.8.
iOS green-lit removal on 2026-07-30 (their decoder treats both as
optional, confirmed at ShareLinkDTO.swift:105-106) and confirmed no
shipped build breaks. Drops RETIRED_FHIR_SCOPE_FIELDS and its spread
from the create and list responses, removes the two properties and
their required-list entries from ShareLinkCreated/ShareLinkList in
the OpenAPI source, and regenerates the spec. The request side was
already closed off by .strict() in an earlier pass; this finishes it
on the response side.
Route tests now assert the fields are absent from both responses
instead of asserting the constants they used to carry.
It could never score. The schema records VO2max but cannot tell a
measured test apart from a device estimate, so every fitness row reached
the scorer unproven and was refused - the pillar has never produced a
value on any account. Listing it on the score settings page as a thing
you can choose, with a line admitting it does nothing, was chrome over a
switch that changed no number.
So it leaves the catalogue: no pillar id, no domain, no scorer, no row,
no wire field. A stored selection that still names it reads back fine -
the resolver has always filtered stored ids against the catalogue and
drops what it no longer knows, so nobody's saved recipe throws or is
discarded over it.
That also fixes the page claiming unsaved changes forever. The save
stripped the fitness pillar out of the selection on its way to the
server, so the answer that came back could never match the form that
sent it, and 'All pillars' left the save button lit no matter how often
you pressed it.
Three checks. The engine tests pin the overdue boundary from both sides:
day 42 of a stated 28-day cycle still counts, day 43 stops counting and
reports fifteen days later than usual.
The round-trip test calls the real GET handler, reads the response body as
text and parses it, so a field that both ends handle but the wire never
carries fails here. It runs the same instant twice for two accounts in
different timezones and gets two different answers, which is what the
account timezone is for. It also checks the ring's cycle day against the
phase engine the coach read uses, so the two cannot tell someone two
different days.
The guard reads the syntax tree of every file under components, hooks and
app, and fails on a grace-period constant, on an overdue verdict computed
rather than read, and on a cycle-day count compared against a sum. It
follows local bindings, so lifting the threshold into a variable above the
comparison does not hide it. A companion suite tries nine disguises against
the same detector and pins five innocent shapes it must ignore, including
an overdue medication dose.
The cycle ring's day count, its phase arcs, and the judgement that a period
is late all used to be worked out in web client code, including the
fourteen-day grace window that decides when the count stops being an
observed fact. Anything else that wanted the same answer had to reproduce
that rule, and a second copy of it is how a ring ends up showing someone a
cycle day their record does not hold.
GET /api/cycle/calendar now carries a verdict: the state, the cycle day,
the ring's arcs, the cycle start, how many days until the next period, and
when the period is late, how late. It is resolved against the user's own
timezone day, which a browser in another zone cannot do. The web wheel,
the wellness-strip tile, the insights teaser and the temperature chart all
render it, the grace constant is gone from the components directory, and
the spec says the field is required.
The overdue caption now names the number of days instead of only saying
later than usual.
A dedicated settings page lists every scorable pillar grouped by the area
of health it speaks to, so the fact that blood pressure, glycaemia and
lipids are three pillars of one area is visible rather than buried. Each
row shows the three things that were never separable before: whether the
pillar is being recorded, whether it is shown, and whether it counts
toward the score. Only the last is writable here, and the page says so.
A pillar whose tracking is switched off is not listed at all, because it
is not waiting for anything. A pillar this build cannot score yet is
listed, disabled, and says why. Wellbeing under safety signposting is
named as safety guidance and never as a mistake in the selection. The
refusal for a selection too narrow to produce a score comes from the
server and is shown in the reader's own language.
The score's foot disclosure gains one link into the page.
Until now the set of pillars behind the Health Score was assembled from
the module switches alone, in a stack of ternaries inside the reader. A
person who turned the sleep module off lost the sleep pillar from their
number as a side effect of a setting about recording data, and there was
nowhere else to say what should count.
The reader now reads the stored recipe and narrows it to the pillars a
module is actually recording. The mapping from module to pillar moves
out of the ternaries into a named map beside the reader, where it can be
read and tested. Glycaemia stays fed by either glucose or labs, which
was the one entry a one-module-per-pillar map would have lost.
Nobody's number moves on upgrade. An account that never opened the new
surface resolves to every pillar, and every pillar narrowed by module
availability is exactly the set the ternaries built, so the inheritance
holds by construction with no backfill.
A pillar the recipe selects whose module is off produces no row at all,
rather than a "waiting for data" line. Turning a module off is a
deliberate act, and asking someone for data they chose to stop recording
would be nagging them in the voice of their own settings.
Four suites hand-roll a Prisma stand-in for the backup builder, so a new
section reaches them as an undefined delegate rather than as an empty
result. Each gains the delegate, and the admin restore round trip gains an
assertion that the day comes back with its composition and per-pillar
scores, not just its headline: a row restored without those looks restored
and answers nothing.
A new user-scoped table is outside all three by default, and the two
structural guards said so the moment the model landed: the wipe plan and
the backup verdict list both named it as unclassified. It now joins the
wipe list, rides the backup payload as its own spread section, and comes
back through the restore route.
The classification guards only prove a helper exists in a declared file, so
they would pass an unreferenced restore helper. The integration round trip
goes through the real admin restore route instead, with the table emptied
first so a restore that carries nothing cannot pass by leaving what was
already there.
PATCH /api/auth/me/health-score-config takes the pillars a person
wants counted and stores the rest as the deselection list. A selection
that cannot produce a score is refused with a sentence naming what is
missing, using the same rule the scorer applies at read time. The
write evicts the score caches, and so does the modules route, which
changes the same composition and never did.
Every surface that shows a score now goes through one entry point that
computes it and writes the day down, rather than three surfaces each
remembering to. The write is an insert that yields on conflict, so a second
computation of the same day leaves the first row alone, and a failure is
annotated rather than thrown: a score that renders must not disappear
because a bookkeeping insert did.
The fingerprint covers exactly what the stored composite and band depend on
- the algorithm version, the composition, and each counted pillar's score
with its scoring-mode identity. A pillar that was graded but not counted
stays out of both the fingerprint and the row, because it did not
contribute to the number being stored.
Four things a person notices if they break: a pillar never shows up twice
anywhere in the panel, a failed read never lands in the not-scored list, the
panel does not push the page sideways at 360 pixels, and the whole thing is
there with the briefing switched off. Every one of them was broken on purpose
first to check the test actually goes red.
The label column is 8rem, not 7. Rendered in all six languages, 7rem clipped
the longest label in five of them, two of those by two pixels, which reads as
a bug rather than a truncation. The reserve is 480 pixels, measured against
the built panel rather than guessed: three rows come to 440 and six to 524.
The overview fixture now carries a health score, so the phone-width guard
measures a band with the panel in it instead of an empty column.
The stand-in for the discovery engine took an argument it never read, so
the lint run flagged it. Give the mock a function type instead: the
argument stays inspectable, which is the whole point of the probe, and
nothing is declared and then dropped.
The grader returns the score and its basis together and the pillar builder
copies both across, and each of those ends already had its own test. Neither
sees what happens between them: the envelope hand-off, the reader's narrowing,
the pillar list, the JSON that finally goes out. A field can be produced
correctly, consumed correctly, and never reach anyone, which is exactly how a
payload field shipped earlier this month and carried nothing on the wire.
These tests read the assembled response and assert the basis that arrives, so a
future hand-picked key list on that path fails here rather than in someone's
browser.
The guard read a parameter as required whenever it carried no question
mark and no default, so `Locale | undefined`, `Locale | null`, a locale
widened to `any`, and a default sitting on the destructuring pattern all
walked straight past it. Each of those lets a caller say nothing and the
sentence come back in English, which is the bug the guard exists to stop.
A counter-case pins the other direction: a plainly required locale still
reads clean, so the guard stays quiet on the shape the chain is meant to
have. The correlation read now also asserts the language it was asked in;
nothing else in that file would have noticed it going back to English.
The score is the worse of the systolic and diastolic sub-scores, and
until now nothing said which one it was or how far over its ceiling the
reading sat. The grader now returns that basis together with the score,
as one value, and it is carried as one value all the way to the pillar
so an explanation can never belong to a different grading run than the
number it explains.
The score returns to the right-hand column of the hero band, where it sat
for eleven weeks: the number at the top, then one thin line per pillar that
actually counts toward it. The card that was pinned below the greeting is
gone, so the score has one place on the page again.
Each contributor line now takes its own colour. A pillar scoring 92 used to
be painted red just because the overall score was red.
Anything not contributing is one quiet line instead of a block: a failed
read is named once for all the pillars it took down and carries the retry,
safety guidance is named in full, and everything simply not recorded yet is
counted, with the names a tap away under the score.
Three things are held down here. The route hands the reader's language to
the strip builder, for a cookie and for a stored preference. The pattern
sentence comes back in German for a German reader, asserted word for
word, through the real chain rather than the engine on its own — the
engine could always write German, it was simply never asked, so an
engine-only test would have stayed green the whole time it was broken.
And a cached strip stays with the language it was written in.
The guard reads the declarations rather than grepping them, so renaming
the argument or moving the fallback into a variable does not slip past
it. Its counterpart runs the same detector against those disguises and
insists each one is caught, because a check that cannot fail reads like
proof and is not.
On a German metric page the strip printed its own summary in German and
the pattern line under it in English. The pattern line is a finished
sentence the server writes, and the route never told the server who was
reading, so it wrote English.
The route now resolves the reader's language the same way the
correlations and analytics routes do and passes it down. The language is
a required argument the whole way through — it used to be optional with
an English fallback, which is why a caller could stay silent and still
get a sentence back. The cycle page's lagged rows had the same gap and
are fixed with it.
The strip's browser cache is keyed by language too, so switching
language no longer re-uses the sentence written for the previous one.
The stage-composition chart totalled each wake day, and a nap ends on the
same wake day as that morning's night. An afternoon nap was added straight
into the night's stage buckets, so the column read longer and shallower
than the night actually was.
The composition now asks the same question the night view already asks:
which session was the night. The night's stages are the night's, and the
nap sits on its own band above them, in its own colour, with its own line
in the tooltip. Days without a nap look exactly as they did.
The admin panel offered a toggle for the Health-Score explainer and
described it as the ? next to the delta line. That ? had already been
taken off the insights surface a release earlier, and the caption that
replaced it went away entirely when the health score was replaced by
the reference composite. Since then an operator could turn the switch
off, get a saved confirmation, and change absolutely nothing.
The toggle, its wording in all six languages, its place in the flag
matrix the app and the iOS client both read, and its column on
app_settings are all gone. Nothing is left to promise a control that
does not exist.
A guard goes in with it: every remaining assistant sub-flag has to be
read by some surface, and the panel and the plumbing that carry all of
them by construction do not count as proof.
The last-attempt lookup runs on the zero-rows path, which is exactly the path a
fresh account takes. When it threw, the whole nutrients read returned 500 — so an
account with nothing to show got an error instead of an empty page, and the
feature that exists to explain an empty surface was the thing preventing it from
rendering.
Wrapped so a failed ledger read degrades to the plain empty state and is recorded
for the operator rather than shown to the person. The route's shape assertion now
carries `lastAttempt: null` explicitly, so a field cannot join this response
without someone deciding it should.
The existing test encoded the behaviour this release deliberately changed: the
breadcrumb used to fire only when a row landed, which made the one durable trace
of an ingest conditional on its success. It failed for the right reason.
Rewritten to assert the new intent with the reasoning kept, and it goes red again
if the condition returns.
GET /api/nutrients now looks up the most recent nutrient.batch.ingest
audit row when the window is genuinely empty, and surfaces it as
lastAttempt only when that call landed nothing (inserted === 0 &&
updated === 0). A real success elsewhere is left alone, so an empty
window for an unrelated reason never gets reframed as a failure.
The lookup runs on the zero-rows path only, never on the happy path,
and stays counts-and-reason-codes only - no user-typed content, no
per-entry health values. The reason code never reaches the page as
text: each of the four closed skip reasons maps to its own human
sentence, and the two that have no useful action for the account
holder (unit_mismatch, upsert_failed) say plainly that the entries
couldn't be stored rather than inventing advice. day_invalid is the
one case worth naming a real cause for - a clock or time zone mismatch
on the sending side - without claiming it was a phone, since any
token holder can call this route.
This depends on AuditLog retention: cleanupOldAuditLogs prunes rows
past 365 days by default, so a dormant account's last failed attempt
can age out and the explanation silently reverts to the plain empty
state. Documented at the lookup for whoever next touches that job.
The 409 email-conflict branch had a safe, specific message already,
but no errorCode - the account-section fallback would have had nothing
to translate it through once it stopped echoing json.error verbatim.
Give it profile.update.emailInUse so it renders in the active locale
like every other profile-save outcome, and propagate errorCode through
both route handlers even on the (non-issues) conflict path.
Also updates the /api/user/profile route test for the reported
scenario directly: a valid timeFormat now lands even when gender in
the same PATCH is unsupported, instead of the whole request failing.
A profile PUT/PATCH validated as one safeParse and wrote as one
transaction, so a single rejected field took every sibling change down
with it - editing height and gender together lost both, and onboarding
lost a whole baseline step to one field. The schema has no cross-field
dependency, so applyProfileUpdate now re-validates each present field
against its own schema and writes whatever validates; only a body where
nothing validates is refused outright, naming the field that blocked it.
The top-level error string also stopped being a raw Zod message
(issues[0].message) that could read "Invalid option: expected one of
"MALE"|"FEMALE"|"OTHER"" on a person's screen. It's now a person-safe
sentence plus a stable errorCode for the web client to localize; the
full per-field detail is relocated (not deleted) into details.issues,
matching the multi-issue envelope the iOS contract already expects from
other write routes.
SubPageShell insets its own heading to the card body edge rather than the
container edge, so a section heading or a meta line rendered flush left sat
16 px to the left of everything above it. The day-context heading, the sport
chips and the count line now take the same responsive inset.
The list hook already returned the canonical total and the page threw it
away, so the surface never said how much history it was showing. Render it
as a meta line above the rows.
The route and the hook already accepted a sport, with nothing to reach it.
Add the chip row. Its vocabulary comes from the unfiltered read, which is
the same query the list itself runs when no sport is chosen, so the row
costs no extra request and choosing a sport can never empty the row it was
chosen from. A filtered view falls outside the server prefetch and pays one
client fetch; a filter that matches nothing says so instead of borrowing the
first-run empty state.
"How does this compare to last time?" is the most likely next question
after reading a workout, and answering it meant going back to the list and
scanning for the one before.
Resolve the previous session server-side, through the same canonical picker
the list uses, so the link can never land on a duplicate row recorded by a
second watch, and render it beside the own-history average line. Null when
nothing older exists, and then no link is shown.
The stats card's hand-rolled heading moves to the icon-less TileHeader
while the file is open.
The "That day" card took the workout, dropped it, and offered three chips
to Pulse, Sleep and Mood. None of those pages accepts a date, so every chip
landed on an all-time trend surface with the day nowhere in sight.
Replace it with the day itself: the intraday pulse chart pinned to the
session's day, the night the person woke from into it, and that day's mood
entries. All three reads are addressed by the server-resolved dayKey, so
nothing here decides which day a workout belongs to.
The two outbound links that remain are undated and say what they lead to,
Sleep trends and Mood history. Sleep and the intraday chart mount only when
their module is on, so a switched-off module cannot paint as a failed read,
and a query that has not answered yet shows a skeleton rather than claiming
the night was empty.
The detail page also drops the description it borrowed from the list.
The detail payload carried the session's start timestamp but nothing that
said which local day it belongs to. Anything that wants the day around a
workout had to slice the ISO string, which is the browser's day, not the
person's: a 20:00 UTC session reads as the 15th in London and the 16th in
Auckland.
Resolve the day server-side from the user's timezone and ship it as
dayKey. Additive, so a native client that does not read it is untouched.
The score had two mounts: a compact face in the hero band and a
nine-block stack further down the overview. The stack also rode inside
the daily-briefing branch, so an instance with the briefing switched off
lost the whole breakdown.
Fold both into one progressive-disclosure card pinned between the
greeting and the customizable region. Collapsed it reads as the score
face: the ring, the band sentence, the weekly delta or the honest reason
there is none, Rest Mode, the tension and return-to-baseline lines, and
the coverage meter. Opening it adds a three-across pillar grid, the
named list of pillars that are not scored yet, the personal weight goal,
and the method footer with its cited standard.
The card is deliberately not a section in the insights layout registry:
an id a saved layout has never seen merges in as default-invisible,
which would have deleted the score for every account that has ever
customised the page.
A pillar the server gated stays visible by name with its reason instead
of being drawn as a zero, safety signposting leads that list, and a
pillar whose read failed gets an error row with a retry rather than
silence. The hero band goes back to the full-width greeting, the shape
it already had for an account without a score.
nutrient.batch.ingest only reached the durable AuditLog table when
inserted + updated > 0, so a batch where every entry was rejected
(unit mismatch, out-of-range value, invalid day, a write failure) left
the exact same empty trail as a phone that never called the endpoint
at all. That made an empty nutrient_intake_days table unanswerable
from the durable record - the question this surface exists to answer.
Record the call unconditionally, the same shape measurement.batch.ingest
and workout.batch.ingest already use (counts only, no per-entry health
values, no user-typed content), plus an aggregate skip-reason breakdown
so an operator can tell, from the row alone, that the phone posted and
why nothing landed.
HTTP status and the per-entry response shape are unchanged - a batch
endpoint returning 200 with per-entry outcomes on a partial failure is
the correct, documented contract and native clients already decode it.
The page's overview query shares queryKeys.nutrientIntake(30) with
MicronutrientsCard, which already renders its own QueryErrorCard on a
failed read. But the page's empty-state check ran first and treated
undefined data (the failed-read state) the same as a genuinely empty
window, returning "no nutrient data yet" and short-circuiting before
any of the three cards - including the already-correct one - ever
mounted. A self-hoster with HealthKit permissions granted and a read
that actually failed saw the same blank invitation as someone who
never logged anything.
Add the isError branch above the empty-state check so a failed read
surfaces its own QueryErrorCard with a retry, and cover it with a test
that renders the actual page (not just the card in isolation) so a
regression here can't hide behind a passing unit test again.
