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 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.
Resilience sits behind Oura's `stress` scope, not `heart_health`, so a
connection that granted every scope HealthLog asked for still answered 401
on `daily_resilience`. `src/lib/oura/scope.ts` now maps every collection the
sync reads to the scope the live API enforces and is the one source for the
authorize request, the per-collection permission detection, the reconnect
hint and the settings card. The request asks for `stress` as well.
Oura names a missing scope in its 401 body ("Token is not authorized access
stress scope."), while a dead token reads differently. A collection refusal
now carries that scope: it spends no token refresh, never counts toward the
reconnect threshold and marks only the collections it names. A 403 (a lapsed
membership) is a persistent failure rather than a reconnect. The callback
also records what the token response says was granted, so an unticked
permission shows on the card before the first sync.
A browser can deliver an OAuth callback twice with the same code. Both
requests exchanged it, and Oura answers a reused code by revoking the token
the first exchange issued. Every connect callback (Oura, Polar, Strava,
WHOOP, Withings, Fitbit, Google Health) now claims its state in
`oauth_callback_claims` before the exchange: one request exchanges, the
duplicate waits for it and redirects to the same page without touching any
token. The ledger flows claim inside the transaction that consumes their
state row. A failed exchange settles with its error page, and a new connect
mints a new state.
Oura token refreshes are serialised per user with an advisory lock, so
overlapping syncs no longer spend the same single-use refresh token, and the
write stays conditional so a reconnect's new grant is never overwritten by a
refresh of the old one.
An audit row whose address no database can place stayed without a
location, so every hourly pass looked it up again for its whole 30-day
window, and finding it walked every audit row of those 30 days through
the created_at index.
Migration 0418 adds audit_logs.geo_attempted_at and a partial index on
the rows still missing a location or carrier. Every row a pass looks at
is stamped, and a row tried less than seven days ago is not picked
again, which still lets a range a later GeoLite2 release learns resolve.
The candidate read goes through the partial index, which holds only the
backlog.
readAllTimeExtremes read every raw reading of weight, blood pressure and
pulse twice on each call, a sequential pass over the measurements table
that made it the largest read on the database. The DAY tier already
holds the same per-source day fold except for the extremes of the
readings themselves: min_value and max_value widen to a row's own
intra-hour range.
Migration 0417 adds reading_min_value and reading_max_value to
measurement_rollups. The writer fills them from the same aggregate, and
the boot re-fold refills existing rows through the arm that already
watches sum_xy. The reader folds the tier for whole UTC days inside the
fold window and the raw rows for the rest: older days, the partial day
a lookback floor falls in, and any type whose tier rows lack the new
columns. The raw arm reads narrow columns once instead of twice.
An integration test compares the result with the previous query on a
seeded history with two sources per day, hourly pulse statistics with
their own range, readings older than the window, midnight edges and
deletions, and shows the tier is the path that answers.
A marked migration's DO block holds the locks it takes until it commits,
so an app transaction taking two of its tables in the other order can
deadlock with it. The block then rolled back whole, exactly as on a lock
timeout, so the boot retries 40P01 for marked migrations as it does 55P03.
Corrects 0415's note that the drops hold their lock for an instant.
0416 ran DROP INDEX CONCURRENTLY at boot, which waits without bound for
every transaction on the table; a pg_dump or a backfill outlasted the
start period and the next boot stopped at P3009. The migration now tries
a plain drop with a two-second lock wait and tolerates the timeout, and
the nightly measurement maintenance drops what is left concurrently under
a bounded wait, retrying the next night. A fresh or shadow database takes
the lock at once, so the history still ends where the schema does. The
guard refuses a concurrent drop in a migration and ties every retired
index to a tolerant one.
The timeline lane, the day view and the life-events service read every
LifeEvent column; the column-reader sweep counts all six as consumed once
the markers are gone.
Twenty-one foreign keys with ON DELETE CASCADE or SET NULL had no index
leading with their column, so deleting a parent scanned the child table
once per row; medication_intake_events.medication_id was the one an
account delete paid for. Seventeen small-table indexes and the measurements
(user_id, type, measured_at) index repeated the leading columns of another
index and only cost writes.
Migration 0415 adds and drops the small-table ones in one DO block under a
bounded lock wait; 0416 drops the measurements index concurrently, in a
file of its own. An integration test holds the schema to both rules from
the catalog, each with a counter-check, and compares the plans of the
user-and-type query shapes on a seeded table with and without the dropped
index. The lock-timeout guard now also requires a CONCURRENTLY statement
to stand alone in its file.
medication_compliance_rollups lost its last reader when compliance moved
to the schedule-anchored computation, yet every dose write still upserted
it, a boot backfill refolded it, and the wipe and backup plans carried it.
The per-dose hook keeps the one derived row that still hangs off a dose
day, the supplement nutrients, under dose-day-refresh. The pending-row
mints (today projection, reminder) no longer call it, since an untaken
dose adds no nutrients. The import job finishes without its per-day
recompute phase; its progress keeps touchedDays and rollupProcessed on
the wire, inert and documented as deprecated. The backfill queue is
retired on boot and migration 0414 drops the table under a bounded lock
wait.
migrate deploy runs a migration file statement by statement, so the
top-level SET LOCAL lock_timeout in 0412 did nothing: the migration
waited as long as the lock was held, with every write to measurements
queued behind it, and a file that failed half-way stayed half-applied.
0412 now takes its locks inside one DO block with a statement-scoped
timeout, which rolls back whole, after an idempotent CREATE OR REPLACE.
The entrypoint runs migrate deploy through scripts/migrate-deploy.mjs.
A 55P03 failure of a migration marked -- @retry-on-lock-timeout is
marked rolled back and retried after 15/30/60/120/240 s, read from
Prisma's report or, after P3009, from the stored row. Every other
failure stays fatal. A guard holds migrations to the shape that makes
the marker true, and 0411/0413 add their columns with IF NOT EXISTS so
a manual re-run is safe too.
CREATE TRIGGER waits for an autovacuum that is preventing wraparound, and
every write to the table queues behind the waiting request, the running
release's included. SET LOCAL lock_timeout fails the migration after ten
seconds instead, and the file rolls back whole.
One run reads at most forty pages of a hundred activities. A longer history
ended as incomplete with no note of how far it got, so every boot read the
same newest pages again, spent up to 190 of the instance's 200 requests per
fifteen minutes on them, and never reached the older activities.
The run now records the start of the oldest activity it read and sends the
next run for after the rate window; that run asks Strava for the activities
before it. A run that gets no further records nothing and sends nothing. The
place is cleared when the backfill completes.
users.insights_cached_text held the model's briefing, readings and
recommendations about the account in the clear. Migration 0411 adds
insights_cached_text_encrypted (AES-256-GCM, binary layout, purpose-bound
label) and a partial discovery index; the free-text encryption backfill
seals the existing rows one at a time, fail-closed, carrying updatedAt and
guarded on the value it read. Every reader, writer and clear goes through
cached-text-cipher.ts, and a guard keeps the column names there. The
column joins the encrypted-column registry and the key-rotation script,
stays out of backups as operational, and is reset by the data wipe.
`updated_at` sits in the sync-feed index, so every update that moved it
wrote a new row version on another page and an entry in every index.
Provider re-syncs rewrite many unchanged rows, which grew the table to
several times its live size and sent each unchanged row down the sync
feed again. Migration 0412 adds a row trigger that keeps `updated_at` and
`sync_version` when an update changes nothing else, so such an update is
heap-only and the feed stays silent; it sets `fillfactor = 85` and a 5 %
autovacuum threshold. The maintenance queue gains a nightly check that
vacuums when dead rows pass a tenth of the live ones and warns when the
heap is more than three times what its live rows need, which only a
`VACUUM FULL` in a window gives back. The admin card keeps showing the
operator's runs only.
A resumable collection counted the pages it had written across every
backfill attempt and stopped at its ceiling (10,000 for heart rate). A
watch that records heart rate every few seconds reaches that count two to
three years back, and since it never reset, every later slice stopped at
the same place, failed as stuck, and the backfill was never stamped
complete.
A walk is now stopped only when it stops moving: 20 pages in a row that
reach no further back than the pages before them end it. A history
backfill reads back at most GOOGLE_HEALTH_BACKFILL_HORIZON_YEARS (20 when
unset). A data type that ends either way counts as finished, and where and
why it ended is kept in backfillProgress past the completion stamp. An
oldest-first list is read whole, as before. The slice chain's ceiling is
derived from sixty days of back-to-back slices instead of the old page
count. An account left at the old ceiling continues from its edge with
the next slice.

Connect, status, places, settings, test, sync and disconnect replace their
stubs. A nightly job (03:20) and the connect backfill read the timeline,
visits and residency endpoints through safeFetch and store one row of daily
values per local day: distances, places visited, minutes away from the home
place and the sealed country with its travel-day verdict. A private instance
needs its exact origin in DAWARICH_PRIVATE_ORIGINS.
The connection joins the shared ledger and the connection health model,
watched for errors only. The day carries a movement block, the model
projection drops the travel country, the two movement channels join the
correlation matrix under the environment module, travel days become trip
suggestions, and the days travel in the environment backup section.
Three levels (frugal, standard, full) with an operator ceiling and default
and a per-account choice within them, resolved in the capability layer for
the record and published on GET /api/auth/me as ai.usage: the level in
effect, the stored choice, the bounds, why (user, default, admin_cap), the
three options with whether each is allowed and an estimate of tokens per
day scaled from the record's last seven full days of coach_usage, and the
measured mean. A delegate sees the level, never the owner's spend.
PUT /api/auth/me/ai-usage stores the account's own choice or null for the
default, refusing a level above the ceiling with 422 ai.usage.aboveCeiling
and meta.maxLevel. The new supplementLabel capability needs standard or
above; below it the capability is unavailable with the new usage_level
reason, refused with 403 ai.usage.levelTooLow and meta.requiredLevel.
Refs #1217
POST /api/biomarkers/{id}/merge folds markers into one in a transaction,
converting readings where the registry knows the units and refusing the
whole merge where it does not; a dry run answers the same result and
writes nothing. Aliases appear on the marker and are edited through the
marker's PUT. Scan and document review rows name the matched marker or
offer up to three, and a chosen marker is remembered as an alias. The
doctor report, FHIR and MCP group readings by marker. Aliases and the
merge ledger travel through backup and restore.
Migrations 0402 to 0410: AI usage levels, biomarker aliases and merges,
medication ingredients (with the supplement label run kind), life
circumstance fact kinds, AI sections and AUDIT-C, Dawarich context, the
pulse day-mean method, intraday hour buckets, the readable location drop
and five relation link tables. Every new column carries its reader or a
pending-consumer marker.
0409 refuses to run while any home, location period or stored day still
holds a readable location, and names the counts. Locations are read from
the sealed copy only; the encryption backfill no longer handles them, and
the demo seed writes sealed locations only.
The new tables are backed up and wiped, the new sealed columns are in the
rotation registry with labels of their own, the AI usage level and the
life-circumstance confirmations travel with the backup, and the wellbeing
score reads the mental-health screeners only.
Migration 0401 turns healthkit_type_syncs.type into text so the ledger can
hold MEDICATION_DOSE, and adds last_background_at (seeded from rows whose
latest arrival was a background one). POST /api/medications/intake/bulk
takes syncTrigger and records APPLE_HEALTH dose arrivals; the Apple Health
status read serves a MEDICATION_DOSE freshness entry and lastBackgroundAt
on every entry with arrival facts.
A backfill noted progress only once a whole collection was read to the end.
A heart-rate history of years that one attempt could not finish (its budget,
a rate limit it could not wait out, a single failed request among thousands
of pages) started the next attempt from the newest page again, finished
nothing, and failed with "marker not stamped" on every attempt.
- Every spot-reading collection read page by page now records, after each
page it writes, the oldest sample it has written (backfillProgress.cursors).
The next attempt asks Google only for samples at or beyond that edge. The
edge is held back once a page's write fails, so no rows are skipped.
- The backfill runs in slices of five minutes or 500 pages. A slice that
finished a collection or moved an edge continues with the next one; only a
slice that moved nothing fails, and its error names each unfinished
collection and why the slice stopped. The slice ceiling is derived from the
collections and the page ceilings of the resumable ones.
- A rate limit Google will not lift within a minute ends the slice instead of
failing the walk, and the next slice starts five minutes later. Server
errors, timeouts and dropped connections are retried three times.
- The heart-rate stream is read last, so the light collections finish in the
first slice.
- The hourly sync waits up to eight minutes for a running slice instead of
skipping the account for as long as the import runs.
- Each slice annotates googleHealth.backfill.slice with pages, elapsed time,
stop reason, per-collection status and edges, and reports progress on the
job.progress line.
Fold the ledger state, liveness verdict, plan and scope gaps and the
provider reauth flag into ok / limited / degraded / action_required with a
reason code, the one action, the unavailable types and redacted
diagnostics. Keep the last ten sync attempts per connection for those
diagnostics, publish the state on the integrations envelope, every
per-provider status route and the Apple Health config read, and page the
operator once per failure streak instead of once a day.
The single-reading edit cleared sourceValue and sourceUnit whenever the body
carried a value, and the web edit sheet always sends one, so a date or note
edit erased the "converted from" hint. It is now cleared only when the value
differs from the stored one. The sheet also opened a converted reading at its
stored precision (100.90191999999999); it now starts from the value as the lab
surfaces show it and leaves an untouched value out of the request, so the
stored full-precision number is not replaced by its rounded display.
Withings split its public API into plans on 2026-10-12. A request naming
one meastype outside the free plan is refused whole with status 277, so
every measure sync stopped importing anything, and the 200..299 reauth
range parked the connection at error_reauth.
The measure, sleep-summary and ECG legs now drop the documented advanced
types on a 277, split the rest until the refused keys are isolated
(bounded), remember the refusal per connection and re-probe weekly. 277
is classified persistent and never enters the ledger; connections parked
over it are lifted by the fallback tick, and the held watermark lets the
next run read the whole gap.
Every raw-SQL clock read against a timestamp column without a zone now
writes NOW() AT TIME ZONE 'UTC', so passkey and login challenges, rate
limits, provider pauses, coach usage stamps, tombstone and measurement
windows no longer pass through the session time zone even where the
per-connection pin cannot apply. The regression-window bounds stay naive
UTC timestamps instead of being turned into timestamptz. A structural
guard keeps bare NOW() / CURRENT_TIMESTAMP out of raw SQL outside a short
list of timestamptz targets. The integration test sets the database
default to Europe/Berlin and drives challenge claims, session expiry, the
native sign-in handoff freshness check and the rate-limit window through
the app's client, plus the challenge claim through an unpinned client.
Self-hosting docs describe the pin for an existing or shared Postgres.
A history backfill carried one access token through walks that outlive it.
After an hour every request answered 401, which classifies as a revoked
grant, so the account was parked at error_reauth with a refresh token that
was still valid, and every later run skipped it until a manual reconnect.
Running beside the hourly sync, the backfill also pushed the account over
Google's per-minute quota, and each 429 failed its whole collection.
- Walks take a token source that renews the access token before it expires
and once more when Google refuses it mid-walk.
- A 429 is waited out (Retry-After, RetryInfo, else a doubling backoff) and
the request repeated; it is never a reauth.
- error_reauth only short-circuits a run when the token endpoint refused the
grant (needsReauth). A connection parked by a data request's 401 refreshes
on its next run and clears itself when that run completes.
- One run per account at a time: syncs, the backfill and the sleep repair
share an advisory lock. The hourly poll skips a held account, a manual
sync answers 409 sync_in_progress, the backfill waits a bounded time.
- A backfill attempt records each collection it finishes cleanly
(backfill_progress) and the next attempt resumes with the rest.
- The incremental watermark is stamped with the cycle's start, not its end.
Overlapping sleep segments that share a stage and an end share the natural
key (type, measuredAt, source, sleepStage). A re-score that moved one row
onto a sibling's slot threw P2002 and failed the sync on every run.
- A batch keeps one reading per natural key, chosen the same way each time
(longer segment, then smaller externalId).
- A move that still collides is settled by reconcileExternalMeasurement,
which retires the stale row, instead of failing the sync.
- Updates run before inserts, and the key-format rescue no longer re-keys a
row this batch is moving.
- The sleep replace-by-window protects every session's fresh rows, so two
overlapping sessions no longer tombstone and resurrect each other hourly.

The note for records whose findings predate the seasonally adjusted
engine compared against a fixed calendar date, so findings an instance
kept writing under the earlier engine until its deploy did not count.
The first discovery sync of the new engine now stamps
AppSettings.correlationSeasonalEngineSince before it writes; without a
stamp every stored discovery pattern counts as an earlier finding.
A restore from a portable export reset each pattern's createdAt to the
restore day and dropped the note for good. createdAt now rides every
export, and a file without it falls back to lastComputedAt.
A background job fetches air quality, pollen and UV for every earlier
local day with a reading, mood entry, dose, symptom or workout: after the
update (boot and nightly discovery), when the home is set and when air
quality is switched on. A day with a weather row gets its air quality; a
day without one gets both, at the covering location period or else at the
home, also before the home was set. Days the source does not reach (before
2013 in Europe, before August 2022 elsewhere) stay empty and are not
counted.
Pending days are grouped by coarse location and cut into ranges of up to
90 days, joining days at most 14 apart, newest first. A run holds itself to
300 of the account's 400 daily calls and half of each instance window,
stores its progress on the user (migration 0391) and sends a follow-up while
it makes progress; a budget stop waits for the next discovery. The
Location & weather card shows the progress.
The air-quality client now asks pollen and dust from 2021 and skips the
request outside Europe before CAMS global starts.
created_by_id cascaded, so a Guardian who deleted their own account took
every handover they had issued with them, including a claimed one whose
decision the new owner had not made yet. The claim had already applied
the proposal, possibly MANAGE for a co-Guardian, and the owner lost the
one place that asks them to confirm it.
The column is nullable now and cleared on delete (migration 0390). An
unclaimed link without a creator is refused like any link whose creator
lost access. A decision that names a Guardian whose account is gone is
refused with 422 instead of failing on a grant for a missing account.
The daily-mean consolidation and the dense hourly fold cut at
`now - threshold` instead of a local day boundary. A day was folded in two
runs and the second run overwrote the stored mean with the mean of the
later part alone: every mean-type day, and the boundary hour of every
heart-rate, HRV and SpO2 day, plus the derived resting figure and the DAY
rollup of such a day. The Health Connect importer split its raw window at
the same unaligned instant.
- Fold up to the start of the account's local day the threshold ends in
(`foldBoundary`), for every consolidation pass and the Health Connect
importer's raw/hourly split.
- A window that already has a live `stats:` row is refolded from every
sample of it, live rows plus the fold's own tombstones; with none left
the stored mean stays.
- `folded_window` refuses a raw sample only when its local day lies before
the aligned boundary and a live `stats:` row of its source covers it,
also within reach of the sample after a timezone change.
- A deletion inside a day the fold had not finished is class B.
- Add a one-time, resumable fold repair per account that recomputes each
hourly and daily mean from its remaining samples and writes only values
that differ, recorded in `measurement_fold_repairs` (migration 0389).
- The compaction-tombstone purge waits for the repair per account, and the
boot sends no purge run before one account is repaired.
- The restore keys live `stats:` ids by source, and writes compaction
tombstones back from a file older than the account's repair, resetting
the repair.
