A grant has always had an access column and `inviteGrant` has always written
READ into it. That was the right way to ship the first version: "this release
never grants write" was a property of the file rather than a promise in a
comment. Remove it deliberately now, so somebody sharing their record can offer
reading or reading plus adding.
The level is a required argument to `inviteGrant` and is defaulted in exactly
one place, the invite schema, where an omitted field becomes READ. An older
client's payload therefore stays valid and stays narrow, and the domain module
never guesses a level nobody named.
There is no upgrade path and that is the decision, not a gap. A grant is READ
or WRITE from the moment it is offered and stays that way until somebody ends
it. Widening a live one would change what the delegate agreed to without asking
them again, and their consent is half of what makes a write grant legitimate.
The way up is a new invitation, accepted again.
The audit row and the wide event carry the level: "who was given what, and by
whom" is the question that row exists to answer.
Three additions to the contract, all of them things a native client cannot
work out on its own.
`GET /api/auth/me` enters the spec for the first time, and enters it loose:
`accountAccess` is specified in full, the remaining preference fields are
declared open rather than half-enumerated. The endpoint has never been in this
document and its payload carries thirty-odd keys no contract has ever named;
specifying a subset and closing the object would publish something the server
does not keep.
`X-HealthLog-Account` is published as a reusable parameter with no route
referencing it, which is the honest state of the contract — the routes that
read another account's record arrive with the surface migration and will
reference it as they land. The header is live in the resolver today, and a
client needs the description before it can be built against a tagged spec: the
value comes from `accountAccess.accounts`, it is a selector and never a
permission, and it must never ride the sync engine, device registration, or an
auth call.
`GET /api/account/activity` carries `retentionDays` in the response and says
why: the window is operator-configurable, so a client that assumed 365 would
tell somebody their record was never opened when the honest answer is "further
back than this reaches".
The parameter is defined in the sharing route module rather than the shared
components block, so the boundary guard keeps holding the header's name to two
files — the resolver that reads it, and the one place that publishes it.
The lifecycle surface under /api/account. An owner offers read access to
somebody already on the instance, the delegate accepts, either side ends
it, and a browser session points itself at a record it has been granted.
Ending a grant clears the acting-account carrier on every session of the
delegate pointing at that record, in the same transaction that stamps the
row. Split apart, a revocation would leave a browser inside a record it
can no longer read: every request refused, the banner still naming the
owner, nothing on screen able to explain it.
Revocation has no step-up and no confirmation step. Reducing access must
never be harder than granting it was.
Grant management is non-delegable by construction rather than by a check:
every route here resolves through bare requireAuth(), which refuses while
the caller is acting on another account, so no code path through them
runs as somebody else. The switch endpoint is the one actor surface, and
it is the way back out. A delegate already inside a record renounces
after switching out, one request, rather than the fail-closed default
growing an exception that later gets widened.
The state machine is not re-implemented anywhere: routes call the grant
module's predicate and its transitions, and the session carrier has one
writer.
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.
Apple Watch ECG recordings reach the record straight from the app instead of
only through an export archive. One recording per request, gated by the same
switches that already govern reading them.
A recording is now identified by what it is rather than by what a source calls
it, so the same strip arriving through both doors converges on one row. The
migration that adds the constraint resolves the duplicates already stored: it
keeps the row holding the waveform over one holding only a verdict, and moves a
removed row's event link onto the row that is kept. The losing rows are deleted.
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.
The cycle ring stops working out its own verdict and reads the server's. The
constant that made that possible is deleted rather than deprecated, because a
constant left in client code is a constant that gets copied again, which is how
the other client's ring froze in the first place.
The score settings page takes the shape the other settings cards have, loses a
pillar that could never score, and turns green where the app's other two scores
already did. A saved selection now comes back as it was sent.
Five gaps in the published specification are closed, including a route that
shipped this morning and was never described at all.
/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.
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.
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 medication on a rolling interval had its expected dose anchored on the moment
the person actually injected, and was then checked off against the moment it was
planned for, with six hours of tolerance. Those two are allowed to sit days
apart, because a dose taken late still counts, so the dose someone's own
injection created could never be marked done. It stayed open, went overdue, and
the app asked for it again.
No editing was needed to reach it. Taking a weekly dose a few days late was
enough, on any account. Push reminders read the plan rather than the entries and
were never affected, so this was on screen, not on a phone.
The Health Score stops being a by-product of switches meant for something else.
It gets its own page, its own recorded history with the recipe that made each
day, and a comparison that refuses to draw a line across two different
definitions.
An account that upgrades keeps the composition it already had, so the number
does not move on its own. What changes is that the composition is now visible
and yours.
The dashboard snapshot copies it off the composite, the daily digest
copies it off the snapshot, and the derived-metric payload already
carries it inside the composite value. Optional on both DTOs like the
score identity fields beside it, so older cached bodies stay valid.
The digest's score object is additionalProperties:false and had never
declared deltaReason, scoreVersion or composition, all of which it has
been sending. A generated strict decoder would have rejected the real
payload, so they are declared here too rather than left standing next
to a field that documents itself correctly.
Changing which pillars count is an act the person performed, not
something that happened to their health. Until now the week-over-week
comparison could not tell the difference: both windows are computed in
one request under whatever recipe is in force right now, so the pillar
sets agree, the subtraction looks legitimate, and the dashboard could
announce "your score dropped 14 points" to someone who had just come
back from the settings page.
The recipe now carries its own dated identity, and the delta guard
compares against it the same way it already compares against the global
method boundary: a recipe that changed between the two windows
suppresses the delta with a new reason, config_changed, and the surfaces
that gate on an unexplained delta stay quiet. The score record stores
the recipe version and its change date on every write, resolved from the
same stored blob the composition came from, so a row can say which
recipe produced it. A new series module reads those versions back, marks
the first day after a change as a break, refuses to join the composite
line across it, and keeps the per-pillar rows running through it: a
pillar is graded against its own reference band and stays comparable
when the average of the pillars does not.
The notice key folds the person's recipe version in beside the method
version, so a change in either raises the existing dismissible notice
once and dismissing one never dismisses the other. An account that never
chose keeps its old key untouched.
Every fix in this release is the same shape underneath. Two places in the code
were each deciding something they both had to agree on, and nothing made them
agree: two copies of the due-day rule, two clocks on one card, two server caches
behind one page, two ideas of where a nap belongs.
The version anchors, the changelog and the published specification move together
as usual.
Thirty-four changes, most of them one shape: something the server or the screen
already knew and did not say. A closed schema that omitted three fields it sends.
A fence around sensitive data that the contract never described, so the native
client dropped an affordance rather than risk crossing it. An ingest whose only
durable trace fired on success, leaving "did the phone even post" unanswerable. A
profile save that discarded valid fields to punish an invalid neighbour. A card
titled "that day" that received the day and threw it away.
The correlation-discovery engine always sets shrunkR (the
sample-size-shrunk effect) and tier (the phrasing-confidence class)
on every surfaced pair, but the closed DiscoveredCorrelation schema
never declared either — same defect class as the dashboard snapshot:
additionalProperties: false rejecting a field the runtime actually
sends. Both are required, matching src/lib/insights/correlation-discovery.ts.
GET /api/dashboard/snapshot is additionalProperties: false in the spec
but the runtime emits three blocks the schema never declared: the
band/target math (targetBands, always present), the score-card
narrative (healthScore.tension / healthScore.returnToBand, additive
optional fields), and the briefing recall/forward-look
(briefingMemory). A strictly generated client rejects the real
response as a result.
Adds all four to dashboardSnapshotResponse with the exact runtime
type, optionality, and nullability, matching DashboardSnapshot in
src/lib/dashboard/snapshot.ts and the DTOs in
src/lib/dashboard/score-narrative.ts. No route behaviour changes.
"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 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.
GET /api/medications/intake/dose-history-import/{jobId}/status reads
through the same readMedicationIntakeImportJob projection as the
per-medication route, so both 200 responses now point at one shared
MedicationIntakeImportJobStatusEnvelope object instead of two
independently generated copies.
Audited every other route description for a schema named by id that
never resolves to a components.schemas entry. Found one more:
CoachPrefs is named in the coach-prefs PUT description, but every
actual consumer is a .extend() of it, so the base never carried
forward to a $ref. Force-registered it the same way as the
dose-history fatal-reason enum. The remaining unresolved meta ids are
request/query schemas zod-openapi inlines rather than hoists — none of
them are named by id in another schema's prose, so nothing points a
reader at a component that silently isn't there.
Documents POST /api/medications/intake/dose-history-import and
GET /api/medications/{id}/intake/import/{jobId}/status, including the
full 16-value MedicationImportSkipReason set the v1.33.0 shape widened
to, read straight from MEDICATION_IMPORT_SKIP_REASONS so the two never
drift again.
Also force-registers MedicationDoseHistoryImportFatalReason into
components.schemas: the 422 description names it, but nothing else
$refs it, and zod-openapi drops unreferenced schemas silently.
Documents POST /api/oura/sync, /api/polar/sync, /api/strava/sync,
/api/nightscout/sync (all four share the resolveSyncOutcome shape) and
GET /api/google-health/sync/status, matching the routes' own
sanitising/clamping logic field for field.
Documents the saved doctor-report scope endpoint, reusing the real
savedReportProfileSchema so the spec's leaf cap and version literal
stay tied to the source of truth.
The field has been served on both routes since v1.28.13 but was
missing from ShareLinkCreated and ShareLinkList, which are
additionalProperties: false.
GET /api/meta/capabilities dropped group membership at the wire: it
shipped a flat group-id list and a flat leaf list with no boundary
between them, so a native client could not tell which leaves live
under which group, or which group is the fenced sensitive tier. That
made it unsafe for the client to offer a "select all" affordance for
any group, since it could not mirror the server's fence against
bundling more than one sensitive leaf behind a single control.
Add SHARE_GROUPS to the report-selection catalogue, derived from the
existing REPORT_GROUPS/MEASUREMENT_LEAF_GROUP/STRUCTURED_LEAF_GROUP
maps: each group now carries its member leaf ids, and the group whose
id equals SENSITIVE_GROUP_ID carries sensitive: true. share.groups in
the capabilities response now ships this shape instead of bare ids;
share.leaves is unchanged. Update the OpenAPI schema and regenerate
docs/api/openapi.yaml.
Add an invariant test asserting every leaf in the flat leaves set
appears in exactly one group and no group carries a leaf outside that
set, plus a check that exactly one group is flagged sensitive.
GET /api/insights/rhythm-events was never in the spec, so a client had
nothing to generate a type from but the three-value ECG classification
next door — reusing it would drop VERY_LOW / FIRED. Register the route
with its own RhythmEventClassification carrying all six
RhythmClassification values; the ECG enum stays untouched at three.
Carries the four fixes that landed after the v1.34.1 tag plus the two found while
reviewing them.
The workout collapse that shipped in that batch only worked on the workout list,
because it keyed a session on a field three of the five callers never fetched.
Those three kept averaging one session into a person's baseline more than once.
The service-worker fallback version had drifted a release behind with nothing
checking it; both halves now have a gate.
The badminton mapping added the enum member in the Zod registry and left the
generated spec behind, so the drift gate failed. One line, `- badminton`.
Third failure this branch revealed in sequence: the formatter hid a red test,
the red test hid this. Each gate only runs once the one before it passes, so a
single unformatted line kept two real problems invisible.
v1.33.1 claimed custom cycle symptoms were carried in backups. They were not,
and the same release turned the old silent drop into a hard failure, so the
accounts the fix was written for went from losing one symptom link to being
unable to restore at all.
