Strava rotates its refresh token on every use. The sync relied on a
compare-and-swap alone, so two overlapping runs could both spend the same
token; the refresh now runs under the per-user lock.
The status route refreshed an expiring token on its own, without the lock
the sync takes, so a status read and a sync could spend the same one-time
refresh token and park a healthy connection at reconnect. Both now go
through the kit.
A provider describes where its grant lives and how its token endpoint is
called; the kit reads the grant, refreshes it under the per-user advisory
lock, re-reads under the lock so a peer's refresh or a reconnect wins, and
writes back only over the refresh token it spent. Retry-After is read in
one place, both forms, with a cap.
The preparation window now carries to, the booked visit's own day on
the record's calendar, and the report offer uses it. Cutting the end in
the reader's zone was wrong for a guardian viewing a managed profile in
another zone.
Migration 0420 looked for an RMSSD twin by externalId only. A Fitbit or
Google Health SDNN row with no externalId, or another one, on the same
night as an RMSSD row would have broken the measured-at unique key and
aborted the block at boot. The twin check now matches either identity,
a row left behind by a live twin is tombstoned, and an RMSSD tombstone
that would make a live row look twinned is removed so the row moves.
The backup restore applies the same rule and no longer counts a
tombstone as a twin.
A night Withings answered with an error on every read kept the
failed-first slot and failed the sleep leg on every run, holding the
connection in an error state and paging for as long as the night stayed
in the window. Failed reads now count per night and a night is given up
after three, like an unstaged one (a full sync still reads it). A
failed read of a night older than 48 hours, while the rest synced, is a
warning instead of a leg failure.
Without from, GET /api/day/notable started at the last completed visit
of any kind, while the web passes the next planned visit's
preparation.from, so a client that omits from read a different list for
the same appointment. Without from the window now starts at that
preparation day (anchor nextVisit, documented in OpenAPI); with nothing
booked it keeps the last completed visit or the 90-day fallback.
One failing per-night stage read threw out of the loop, so the nights
already read and the summary vitals were never written. A failed read
now leaves the others to be written, books the leg failed afterwards
and marks the night to be read first next run. A night that answers
without a stage three times is no longer read on every run; a full sync
still reads it. The per-night record lives on the connection (migration
0421) and is reset on reconnect.
Skipping every day Health Mate holds from another app (brand 18) lost
the steps of an account whose phone steps only Health Mate reads. Such a
day is now skipped only when another connected source (not Withings,
not a hand entry) has steps on that local day; otherwise it is kept.
A backup written before migration 0420 files Fitbit and Google Health
HRV as HEART_RATE_VARIABILITY, and the restore wrote it back verbatim,
undoing the migration for the account (and able to duplicate an
HRV_RMSSD row of the same night, since type is part of the unique key).
The restore now applies the same move: those rows come back as
HRV_RMSSD, a legacy row whose RMSSD twin the file also holds is skipped,
and SDNN personal records set by them are left out as the migration
deleted them.
A preferences response cached by a build before eventDefaults existed
drew every default-on event as off in the matrix until the next refetch.
The no-row rule moves to a client-safe module the server read still
wraps, and the matrix applies it when the map is absent.
The setup flow capped a display name at 50 characters while the profile
took 80, and the profile checked its minimum before trimming, so a name
of only spaces was stored as an empty string. Every surface now reads
one bound (80), the profile trims before validating, and only spaces
means no name on both paths: the profile clears it to null, the setup
flow leaves it unset.
After the Web API turndown every account still saw a Fitbit card that
can no longer connect. The status entry now publishes
retirement.offered: false once the API is gone for an account with no
Fitbit connection, no Fitbit app of its own and no Fitbit data, and the
connections panel leaves the card out. Accounts that had Fitbit keep it
with the retirement notice.
Fitbit and Google Health HRV is filed as RMSSD since migration 0420, so
an account whose only HRV comes from them lost it wherever a display
surface read SDNN alone. The dashboard HRV tile keeps its RMSSD fallback
with Recovery off while the account has no SDNN, and its toggle stays
offered for either estimator. A briefing HRV signal counts as measured
today when either series has a reading. The doctor report already files
RMSSD as its own ungated leaf; a guard now holds that. Readiness, HRV
balance and stress stay on SDNN; a test pins that an RMSSD-only account
renormalises over the other components.
A source a ladder does not name ranks 90, below every source it does.
Five had no place anywhere: a weight typed as a reply to a Telegram
reminder lost its day to a WHOOP strap's estimate, one an assistant
logged over MCP lost to a Fitbit estimate, and a Health Connect day
lost to a hand-typed count.
Health Connect now sits right after Apple Health on the ladders for
what it imports; EXTERNAL, MCP and TELEGRAM sit right after MANUAL, in
the alphabetical order they already broke ties in, so MANUAL still
outranks the person's own bridge. Relative to each other the sources
the ladders already named keep their order, and saved ladders gain
the new entries at their end as before.
Getactivity marks a day that came from outside Withings with brand 18
("external"): an Apple Health or Google Fit day written into Health
Mate. Imported under WITHINGS it was a second copy of data HealthLog
reads from that app's own integration, and on a day it was the only
Withings row it could outrank a native source lower on the ladder.
Such days are now skipped at ingest and counted on the wide event.
Sleep v2 Get answers only the first 24 hours after its startdate. The
sync asked for the whole 30-day window, so it got the night a month
back and nothing since: every night's stages arrived when the sliding
window reached it, weeks late.
The summary now runs first and lists the nights; each night's stages
are read over its own span (at most 24 hours). Every run re-reads the
nights that ended, or that Withings changed, in the last 48 hours, and
fills older nights that hold no stage row yet, eight per run with a
rotation so a night without stages cannot hold up the rest; a full
sync reads them all. Without the night list the last 24 hours are read
as one slice and nothing is swept, since a slice can cut a night.
A summary failure used to be a warning beside a green leg. It is now
the sleep leg's failure, recorded after the stages land.
A 429 in the middle of the activity walk threw out of it before the
upsert, so everything the run had read was discarded and the next run
started over. The walk now ends where the limit hit: what was read
lands, the cursor moves only as far as an oldest-first walk proves,
the failure is booked transient, and the run reports the wait Strava's
X-RateLimit / X-ReadRateLimit headers name (next quarter hour, or
midnight UTC once the daily count is spent). The backfill waits that
long before its next run. `walkPages` learns an `interrupted` page for
this, reported truncated like a walk cut off at its ceiling.
An update mapped from the summary alone (detail budget spent, or the
detail read failed) wrote a null over the calories an earlier detail
read had stored, and over its heart rate and description too. Those
detail-only fields are now kept unless this run read the detail.
Google turns the legacy Fitbit Web API off on 30 October 2026 (support
ended on 30 September). From that day the hourly poll, the backfill,
the sleep repair and the token refresh make no call, the connect, sync
and test routes refuse with `provider_retired`, and the connection
reads as not connected to the health read and the watchdog, so the
shutdown pages nobody and asks nobody to reconnect. The connection row
and everything it imported stay.
The status envelope publishes `retirement` on the Fitbit entry (the
day, whether it has come, the successor), and the Fitbit card shows
when the connection stops, how to move to Google Health (same devices,
one more consent, tokens cannot be carried over) and that the data
stays; sync and connect grey out after the day. Both integrations can
run side by side meanwhile: every type Fitbit writes is laddered with
Fitbit just above Google Health, so a day both deliver counts once.
The test setups pin the turndown off, so the Fitbit suites do not turn
red on the day; the turndown's own tests flip it.
The shipped iOS app routes the rail by intent and resolves the label
from its own catalogue; a new `visit.view` intent would leave its tap on
an appointment inert. The upcoming-visit action keeps `checkup.view`
and `daily.action.viewCheckups` on the wire and only its `href` moves
to the visit. The web card names what that link opens: "View
appointment", or "View appointments" for the visits list.
The setup flow asks for the name the greeting and the reports use, and
the profile route has always accepted it, but no settings surface offered
the field and /api/auth/me did not publish it. A name chosen on the
first day stayed for good.
The account payload now carries `displayName`, the profile card shows the
field beside the username and saves it with the rest of the profile, and
an emptied field clears the name.
The visit preparation and the doctor report offered for an appointment
started at the last visit of any kind. An internist one week and a
dermatologist the next gave the dermatologist a one-week window of
nothing it is about.
The list read now publishes `preparation` on every booked upcoming
visit: the first day of the window, the rule that chose it and the
earlier visit it is the day of. First match wins over the visits that
took place before it: the same practitioner, else a practitioner of
the same specialty (free text, compared without case or spacing), else
the same kind for routine, preventive and therapy visits, else the last
90 days. One query of past visits per page, independent of the list's
own filters. Null on every other row; absent on the detail and on
write responses.
A re-check or reservation that failed itself stopped the scan as
"unavailable", and the review screen said AI had been turned off. It now
stops as stoppedBy error with its own message in every locale, and the
failure is reported as one: an error signal and the worker error
reporter. A scan that failed that way before any row answers 500
aiRuns.failed.
The overspend booked before a further read is now net of the cached
share, as the settlement books it. A reservation that names no known
owner stops the scan instead of taking the user plan's larger cap.
A page's text layer is cut at the last whole line; only a page whose
first line alone runs past the cap keeps part of it, cut at a space or
hard, rather than collapsing to the bare cut mark, and an endless line is
no longer read past the cap. The unused per-call text limit is gone. The
run result's description names every outcome a stopped scan can have.
The workouts leg recorded its failures under its own leg but left the
success to the vitals leg. A leg-scoped success clears only its own
leg, so one workouts failure stayed on the row for good and kept the
connection in error however healthy the exercises read became. Each
leg now records its own success.
AccessLink documents its 403 as missing consent for that data. A 403
on one collection while a sibling succeeded with the same token was
classified reauth_required and put a working connection behind a
reconnect prompt no reconnect clears. Like Oura's scope refusals, such
a collection (or the exercises read, once the vitals leg proved the
token) is now noted on the wide event and not counted as a failure. A
403 on every collection, or any 401, stays one.
Visits are the second tab of `/checkups`, and the bare path opens the
first one, the preventive-care list, which never shows an appointment.
Every surface that listed an upcoming appointment linked it there: the
dashboard's next-appointment line, the Today rail item, the Today
overview fact and the appointment's push notification. A tap on the
appointment landed on the list it is not on.
Each now opens the visit itself (`/checkups?visit=<id>`), or the visits
tab (`/checkups?view=visits`) for a line naming several appointments.
The checkups page reads `view` to pick a tab. The rail item stops
borrowing the check-up item's action: it carries its own label
("View appointment") and intent `visit.view`. The appointment push names
its visit through the producer's `metadata.url` override; a check-up's
push keeps the checkups list.
The same mis-route sat on three links that lead to visits without
being upcoming: a condition's visit rows, the address book's back link
and the onboarding and timeline prompts to add a visit.
`visit-link-guard.test.ts` keeps the visit paths in the builder and
counts every bare `/checkups` per file, each with the reason it names
the checkups list.
Seven surfaces spelled `/checkups?visit=<id>` by hand, some encoding
the id and some not. They now share `visitPath()` from
`src/lib/encounters/visit-links.ts`, the place the next fix extends.
No behaviour change: a cuid encodes to itself.
HRV_RMSSD was read nowhere HRV is analysed: the correlation scan and the
illness engine only knew the SDNN series, so a strap or ring wearer's
HRV never took part in either. RMSSD is now its own outcome channel
(owned by the recovery module, like the summary tile) and its own
illness scan type with a drop read as adverse. It is not merged into
the SDNN channel: the estimators differ in scale, and one series of
both would correlate the change of device rather than the body.
The /notifications matrix read the constant default table, where the
mood reminder is off, while delivery derives it from the reminder card.
An account receiving the reminder saw every one of its channel switches
off.
The no-row default now lives in one resolver that delivery and the
preferences read both use. GET /api/notifications/preferences publishes
it as `eventDefaults`, the matrix renders a switch without a stored row
from that map, and the reminder card refreshes the matrix when it flips.
Fitbit's `dailyRmssd` and Google Health's daily HRV average are both
RMSSD, but the mappers wrote them into HEART_RATE_VARIABILITY, the SDNN
series. The `hrv` ladder ranks both above Apple Health, so an account
with an Apple Watch and a Fitbit had a series that switched estimator
from day to day. The mappers now write HRV_RMSSD, and the `hrvRmssd`
ladder carries both sources where they sat on the SDNN one.
Migration 0420 moves the rows already written (tombstones included,
with a sync-version bump so the change reaches the phone), drops their
SDNN rollup buckets and the RMSSD buckets of every account whose rows
moved, so the boot-time rollup discovery folds those accounts again,
and deletes the SDNN personal records those rows had set. One DO
block, so the move and its cleanup land together.
The shared data/instruction fence removed embedded markers in a single
pass. Removing a marker joins the text either side of it, so a marker
split around another one came back whole after the scrub:
`<<<DOCUMENT_TEXT_E<<<DOCUMENT_TEXT_END>>>ND>>>` became
`<<<DOCUMENT_TEXT_END>>>`, and the same split around any other marker
worked too. Content could close its own fence wherever the helper is used:
the Coach snapshot and self-report, MCP tool results, document reads and
lab scans.
The scrub now repeats until a pass changes nothing, which proves no marker
is left. Content nested deeper than eight levels has every run of three or
more angle brackets cut to two, after which no marker can exist or
re-form. Ordinary text, angle brackets included, is unchanged.
The v2 recovery webhook carries the id of the associated sleep, and a
recovery's rows are keyed off that same sleep id. The delete branch
matched on the `<id>:` prefix, so a `recovery.deleted` event also
soft-deleted every sleep row of that night, and a `sleep.deleted`
event took the recovery with it. Recovery now names its exact ids
(pinned against the mapper's field tags); sleep keeps the prefix minus
those ids.
The targeted refresh for `recovery.updated` passed the same sleep UUID
into `/v2/cycle/{cycleId}/recovery`, which answered 404 and booked a
sync failure on every recovery webhook. It now reads the sleep for its
`cycle_id` first.
The text layer went to the model as the authority for digits. It is not
one: a scanned PDF often carries an invisible OCR layer with its own
mistakes, a subset font can map to the wrong characters, and a crafted
PDF can carry invisible text that differs from what the reviewer sees.
The prompt now calls it a hint only, makes the image authoritative, forbids
adding a value the image does not show, and asks for a low value
confidence where the two disagree. The layer is fenced with the document
text markers, which it cannot close, and so is text mode's OCR'd text.
Each page's layer is capped while it is collected, and a read shares its
text budget out per page, cut at a line and marked, so a long first page
no longer pushes the later ones out.
A further read now first books what the reads so far cost beyond their
reservation, then its own ceiling, both against the cap of the owner the
route judged the first read by, so the counter the next read is judged
against never lags. The wire is re-checked before every read, the first
included. A re-check or reservation that itself fails stops the scan with
the pages read rather than failing it, and a scan stopped before any row
answers with the stop's reason (budget, or the wire's own refusal) instead
of an unreadable page.
The route reserved one read's budget and checked the wire once, and a
20-page report then ran up to 40 calls for many minutes on that single
admission. Every read after the first now reserves its own share of the
day's budget and asks the wire again (aiEgressRefusal) before it is sent;
when either refuses, the scan stops there, keeps the pages already read
and names the rest with stoppedBy budget or unavailable. The run settles
against everything it reserved, with the provider's reported usage net of
its cached share, and a scan that fails after several calls is charged
for them instead of refunded in full.
A rendered PDF page now goes out with its own text layer, read by pdfjs
beside the image, so a digitally produced report's digits, decimal
separators and units come from its characters rather than from a 1600 px
picture. Splitting the PDF into single-page documents would need a PDF
writer the project does not ship; the text layer needs none and helps
every provider. A scanned page has no text layer and reads as before.
Codex's cut reply keeps the text it streamed (on a non-enumerable
property, so no log or event serialises it), and its closed rows are
salvaged like every other provider's. The merge folds a reading only into
one an earlier page listed, never two rows of the same page, and the
printed range is part of the key. OCR'd text the deadline cannot split
small enough for one read is refused up front as labs.ocr.tooLarge.
A scan sent the whole report to one call under an 8000-token ceiling and
validated the reply against a 100-row envelope. A long multi-panel report
lost everything either way: the reply stopped mid-row and failed to parse,
which the person saw as "try a clearer photo", or it held more than 100
rows and the schema refused all of them. One malformed row refused the lot
as well. Reasoning models made it worse, because the call sent no
reasoning setting and OpenAI, Codex and Claude's 5 generation reason by
default against the same output allowance.
A PDF of more than one page is now rendered and read a page per call on
every provider (up to 20 pages), as many reads as the run's deadline
allows, and the pages are merged in order with a reading printed twice
listed once. A photo, a one-page PDF on a provider that reads PDFs, and
OCR'd text up to 4000 characters stay one read; longer text is split at
line boundaries. Each read carries an explicit reasoning off, so a model
that can stop reasoning does and one that cannot gets its minimum budget
on top of the answer's. A reply cut at the output limit is detected from
the finish reason (Codex's incomplete stream included), keeps the rows
that closed before the cut and is named in the result instead of retried;
when no read produced a row the run fails as labs.ocr.outputLimit. A
provider failure after the first page keeps the pages already read.
Rows are validated one by one, the row cap is 400 for the scan and the
commit, and a report past it keeps its first 400 and says how many it
had. The run settles what the provider reported it spent rather than the
fixed reservation, so a page-by-page read still counts against the day's
budget in full.
The signed-state callbacks (Oura, Polar, Strava) claimed the state before
the session, code and issuer checks. A denied consent comes back without a
code, so it spent the claim on a `nocode` error page, and allowing on the
same authorize URL afterwards never exchanged the valid code: the browser
was sent to the stored error page instead. Every check that refuses a
callback without touching the code now runs first; the claim still sits
strictly before the exchange.
Expired claims were swept only when a callback completed, so a quiet
instance kept its last rows. The daily OAuth-state cleanup at 03:20 now
sweeps them as well.
Under the refresh lock, with the row still holding the token just spent,
no peer rotated it, so refresh_token_reused is the issuer refusing the
whole family: it now parks the sign-in instead of being asked again
after every cooldown. Outside the lock it stays a lost race. A refresh
whose compare-and-set write finds the connection gone (the person
disconnected Codex meanwhile) now refuses with reconnect-required
instead of using the rotated token once more.
The keyed refold's day filter and delete compared the naive UTC
measured_at and bucket_start with a timestamptz[] parameter, which goes
through the session time zone; in any zone but UTC neither matched and
the refold left its buckets stale. Both now bind timestamp[] literals.
Keys are refolded in (type, day) order in chunks of 500, and the
rollup-recompute queue describes the runs of buckets a job now covers.
Two callers refreshing one Codex token raced: the loser heard
refresh_token_reused, read it as a dead grant and parked the connection
before the winner wrote its rotated tokens, leaving fresh tokens beside
an expired status. Refreshes now share one flight per process and queue
on the per-credential advisory lock across processes, re-read the row
inside it, use a token a peer already rotated, write the rotated tokens
compare-and-set on the spent one together with connected, and re-read
after a refusal before parking. refresh_token_reused no longer counts as
a dead grant, and neither does a bare 403 without an OAuth error code:
an edge challenge answers a valid grant so, and it keeps the ledger's
timed cooldown instead of parking until the next sign-in.
