POST /api/medications/intake/bulk keeps authentication, its own bulk bucket, the body with its size and schema refusals, the payload schema and the HTTP mapping. The ingest, one 846-line function, moves to lib/medications/intake-bulk/ in the order it always ran: the ownership read, the Apple mirror gate and the batch pre-reads (ingest.ts), each entry's refusals, site, write bookkeeping and P2002 answer (entry.ts), its slot attribution (entry-attribution.ts) and its slot, replay, probe or standalone write (entry-write.ts), then the audit row, the dose days, the snooze, the tails, the arrival record and the checkpoint. The two identical canonical-slot write blocks of the loop are one function now. The route falls from 1044 to 231 lines; no function in the new modules is over 70.
The parity walk recorded before the move (medication-intake-bulk.parity) is unchanged. The per-entry external-id markers name the module that classifies each entry, the batch-surface and key-scope legs read the moved code, and the intake-tracking allowlist and the dense-read guard follow it.
A '/*' inside a line comment opens a block for every guard that strips
block comments first, and the code after it disappears from that guard's
view. Four server comments and one new one did this; reword them.
GET and POST /api/medications/intake keep authentication, the query and body parsing with their refusals, the 404 and the HTTP mapping. The today list moves to lib/medications/intake-today.ts and the cached compliance buckets to intake-compliance.ts. The status update, one 432-line callback, moves to lib/medications/update-intake-status/ in the order it always ran: the event lookup, the record-only rule, the delegated refusals and the injection site (admission.ts), the take in place or onto another slot (take.ts), then the skip or snooze, the audit row, the rollups and the tails (update-intake-status.ts). The route falls from 634 to 149 lines; no function in the new modules is over 70.
The parity walk recorded before the move (medication-intake-status.parity) is unchanged. The sharing and activity-verb guards read the status-update modules beside the route, and the dense-read guard keeps the moved code in scope.
POST and GET /api/medications/{id}/intake keep authentication, the intake and ownership guards, the body and query parsing with their refusals, the delegated outcome-change refusal and the HTTP mapping. The dose write, one 607-line function, moves to lib/medications/record-intake/ in the order it always ran: the injection-site check and the slot attribution (attribution.ts), the replay and dedup answers and the slot, probe or standalone write (write.ts), then the inventory, the audit row, the rollup, the lifecycle and the tails (record-intake.ts). The history list moves to list-intake-events.ts. The route falls from 767 to 200 lines; no function in the new modules is over 75.
The parity walk recorded before the move (medication-intake.parity) is unchanged. The activity-verb guard now reads the awaited audit actions of a delegable write's handler modules beside the route, for this route and for the medication create that moved before it, and holds each module to its route's imports; the sharing guard, the intake-tracking allowlist and the dense-read guard follow the moved code.
GET /api/measurements/series keeps authentication, the query and its
refusal; readSeries (lib/measurements/series/read-series.ts) picks the
reader in the old order (sleep nights, paired blood pressure, the bucketed
read of a dense kind, the raw rows) and adds the direction, change,
reference lines and stat strip. The kinds, units and point shape live in
kinds.ts. The route falls from 752 to 95 lines.
The parity walk recorded before the move is unchanged. The guards on the
verdict resolver, the spread, the pulse day mean and the unit literals read
the new files, the last two with their scope widened to the series folder.
GET, PUT and DELETE /api/medications/{id} keep authentication, the ownership guard, the body and the HTTP mapping. The read moves to lib/medications/read-medication.ts; the edit, one 886-line callback, moves to lib/medications/update-medication/, split along its stages in the order they always ran: the preflight checks and refusals, the schedule normalisation, the transaction (era archive, tombstones, the row update, the pause era, the course write) and the commit tail with its audit row. The delete moves to delete-medication.ts. The route falls from 1270 to 100 lines; no function in the new modules is over 115.
The parity walk recorded before the move (medication-detail.parity) is unchanged. The sharing guard reads the edit and delete modules for the handler body, the intake-tracking allowlists name the modules that now read the schedule and the open slots, the published-DTO leg reads the read module, and the dense-read guard keeps the moved code in scope.
GET keeps authentication, the module gate and the AI capability, and hands
the rest to readWorkoutDetail (lib/workouts/detail.ts): the stored row, the
canonical winner of its cluster, the enrichment reads and the body, as
named stages. DELETE keeps authentication and the HTTP answers; the
ownership check, the synced-source refusal and the transactional removal
with its records, audit, cache and detection tail move to
lib/workouts/delete-manual-workout.ts.
The parity walk recorded before the move is unchanged; the guards that name
the canonical-identity reads and the track readers point at the service.
The route keeps authentication, the slice refusal, the summaries slice, the
cache read and the headers. buildAnalyticsResponse (446 lines) moves to
lib/analytics/response/default-body.ts and calls one module per block, in
its old order: the blood-pressure in-target windows, the glucose summaries
and clinical panel, the correlation hypotheses with their stored patterns,
the Health Score with its Rest Mode framing, and the sleep stages. The
route falls from 761 to 155 lines.
The parity walk recorded before the move is unchanged; the guards on the
glucose window and the bounded reads follow the code.
The status routes kept their old resolve*StatusLocale names as import aliases when the per-card locale resolvers were folded into normalizeLocale. They call it directly now.
Oura, Polar, WHOOP and Strava each keep the transport and endpoints in
`client.ts` and gain `wire-types.ts` (the record shapes) and `map.ts` (the
pure record-to-row mappers, no I/O). Google Health's 1,600-line client
becomes `budget.ts` (slice budget and outcome tally), `request.ts` (error
detail, retry, rate limits), `data-points.ts` (the paginated walker) and a
small `client.ts` for the profile and roll-up reads; its `export * from
"./mappers"` facade is gone and its importers name the module that defines
what they use.
The code moved verbatim; the mapper goldens written before the move and
the provider integration tests pass unchanged.
`oauth-kit/client.ts` builds a provider's consent URL, code exchange,
refresh and deauthorization from a declaration of what differs: endpoints
and scope, client authentication (form or HTTP Basic, with or without the
client id beside it), the fields a grant adds, how an answer is classified
and the refusal named, the error type, and where the token sits in the
body. The seven hand-written copies of the redirect URI, authorization URL,
token post, Basic header and PKCE pair are gone; each provider keeps an
`oauth.ts` with its declaration.
Shared behaviour is now uniform: a 2xx without a token object (an empty or
non-JSON body) is a transient `empty_token_body` failure for every
provider. WHOOP, Strava and Google Health used to return null, and
Withings threw an unclassified SyntaxError; the OAuth wire golden records
exactly these lines changing and nothing else. Oura's live/legacy endpoint
fallback, Google's invalid_grant lift, Strava's Fault summary and Fitbit's
errorType are declared per provider.
POST /api/medications keeps authentication, the body, the validation
answer and the HTTP mapping; the create (the mirrored-medication dedupe and
cap, the one-shot shape refusal, the initial course, the nested schedules,
the insert and its tail) moves verbatim to lib/medications/create-medication.ts
and answers created, existing or refused. The route falls from 541 to 94
lines. The parity walk recorded before the move is unchanged, and the
sharing guard reads the service beside the route for the handler body.
The size baselines take the lower value of the two sides per entry, and every ratchet baseline is written back to what the tree measures now (file and function sizes, version stamps, source reads, import cycles, route body parsing).
GET /api/measurements keeps authentication and the query refusal and hands
the validated query to measurementListResponse (lib/measurements/list),
which tries the list modes in their old order. POST keeps authentication,
the body, the bridge-source refusal and the three validation answers; the
single and combined writes with their shared tail move to
lib/measurements/create/create-readings.ts, the named sleep-stage write to
create-sleep-stage.ts. The route falls from 938 to 274 lines.
The parity walk recorded before the move is unchanged; the guards that name
the measurement writers, the write tail and the bounded reads follow the
code.
The five hand-written registrars (about 5,500 lines, one 997-line function)
are replaced by `jobs/registry/`: one `defineJob` entry per queue with its
cron, schedule send options, policy, work options, lock, lane and a handler
loader. `registerJobGroup` creates, schedules, retires and binds each group
in the order the registrars used; the worker boot walks the groups and runs
their boot discovery.
Handlers load on their queue's first job. The facts a declaration needs at
boot (names, crons, concurrency, send options) moved out of the heavy job
modules into light `*-queue.ts` siblings, and their importers point there,
so loading the registry evaluates 288 modules instead of the 1,164 the
registrars pulled in. The formerly inline handlers moved verbatim into
handler modules under `jobs/reminder/`.
Fitbit's queues live in `fitbit/jobs/definitions.ts` and enter the registry
through one spread, so removing the integration later is that folder and
that line.
`tests/integration/queue-registration-parity.test.ts` proves pg-boss holds
exactly what the registrars left (queues, schedules, bindings, byte for
byte) and loads every handler once. The queue tests and the runtime guard
assert on the registry objects instead of reading registrar source.
The route keeps authentication, the body, the base token, the layout schema
(the inline-schema inventory reads it there), the conflict mapping and the
responses. The rest moves verbatim into lib/dashboard/widgets/, one module per
stage: the layout read and the availability probe for GET, the unknown-id
drop, the refusal report and the stored-field merge for PUT, and the locked
reset for DELETE. The route is 317 lines, down from 513; its longest
function is 85 lines, down from 199.
The parity walk recorded before the move (dashboard-widgets.parity) is
unchanged. The tombstone-read guard now also scopes lib/dashboard/widgets/,
so the moved HRV probes stay policed.
The PUT handler was one 390-line callback. The route keeps the record
resolver, the 404, the body and its schema refusal; the correction moves
verbatim into lib/medications/update-intake-event.ts, split along its
stages in the order they always ran: the start-day floor, the slot
attribution, the in-place edit or the move onto another slot, then the
audit row, the event and the tails. The undo moves into
delete-intake-event.ts. The route is 124 lines; no function in either
module is over 140.
The parity walk recorded before the move (medication-intake-event.parity)
is unchanged. The sharing guard's audit, tombstone and overwrite legs read
the route together with the modules it hands its bodies to, listed in one
map that each route must still import, and the moved-dose provenance leg
now also asserts the original source is carried.
postBatch was a 700-line function. The route keeps authentication, the
per-account preference read, the body caps, the rate limit, the parse and
the bridge-source refusal; the ingest moves verbatim into
lib/workouts/batch-ingest/: the first pass (entries), the duplicate probe
and write plan with the manual-correction rules (plan), the transaction
that writes corrections, workouts, tracks and series (write), and the
orchestrator with the audit, record detection, wide event, cache and
arrivals (ingest). The route is 275 lines.
The parity walk recorded before the move is unchanged; the guards that
name the track writer, the Workout writer set and the per-entry
external-id check point at the service files.
postBatch was one 1255-line function. The route keeps authentication, the
rate limit, the body, the entry cap, the schema and the bridge-source
refusal; the ingest moves verbatim into lib/measurements/batch-ingest/, one
module per stage in the order they always ran: the first pass (prepare),
the measurement writes with their prefilters and set-based insert, the
hourly sums, the sync checkpoint, the audit and wide-event report, and the
cache and arrival tail. The route is 274 lines; no function in the folder
is over 200.
The parity walk recorded before the move (measurements-batch.parity) is
unchanged, as is the set-insert golden. The guards that read the route for
the per-entry external-id check, the plausibility validator, the write
tail, the dense-read bound and the unit audit now read the service files.
Admin, coach, consent, chart-overlay, device registration, insights
feedback and provider chain, ECG ingest, onboarding, search and the AI
provider settings move to parseJsonBody with the same message, error
code, status and wide-event action they answered with. A refusal whose
annotate meta is computed from the issues, or puts its keys in another
order than the helper would, keeps that annotate verbatim in onInvalid.
The routes that still call safeJson do something between the read and the
schema: an optimistic-concurrency token split off the body, a count cap
answered first, a refunded quota slot, a conditional read, a non-Zod
check, or the body handed to a service.
Labs, biomarkers, custom metrics, cycle, anamnesis, illness, measurement
reminders, the measurement edit, medication sub-routes, mood and mental
health assessments still spelled out safeJson, safeParse and the 422 by
hand. Each becomes one parseJsonBody call with the size cap, action,
issue count, error code and status it had. The audit rows and the
unstable-externalId breadcrumbs move into onInvalid, in the order they
ran; where a breadcrumb reads the body, the wide-event annotate moves with
it. A `body ?? {}` or a payload unwrapped from the body becomes `input`.
The medication ingest route reads through the helper too; its Bearer
resolution happens before the read and is unchanged.
132 route handlers spelled out safeJson, safeParse and the 422 refusal by
hand in one of six shapes. Each block becomes one parseJsonBody call with
the same size cap, wide-event action, issue count, error code, message and
status it had, so every response is the one it was. The comments inside
the replaced refusal blocks go with them.
A ratchet (route-body-parse-ratchet) counts the route files that still call
safeJson themselves; the count may only fall.
The module gate and the cycle gate imported each other for one pure
predicate. isCycleEnabled moves to lib/cycle/enabled.ts and both gates
import it from there.
The band minter read DOSE_WINDOW_DEFAULTS through the analytics/compliance
re-export barrel, which loads the compliance display and with it the
scheduling modules that import the minter. It now imports the constant from
the module that defines it. Runtime import cycles fall from 6 to 4.
lib/sharing/grants.ts held both the grant transitions and the predicates
every reader asks (state, level, scope, the live grant for a pair). The
transitions reach into the managed-profile lifecycle and the OAuth connect
target, and both of those read a live grant, so grants, lifecycle and
connect-target formed an import cycle.
The predicates, findActiveGrant and touchGrantUsage move verbatim to
lib/sharing/grant-access.ts, which imports only the database client and
the scope vocabulary. Importers and the mocks that replaced those
functions point at the new module. Runtime import cycles fall from 7 to 6.
api-handler.ts held two modules: the route wrapper and thirteen guards. The
guards now live in lib/auth/guards/, one module per family (the caller,
the acting-account carrier, the record modes, the cookie-only helpers, the
fresh-factor and recent-proof gates, the Bearer elevation, MFA management).
api-handler.ts keeps the wrapper and re-exports every guard, so it stays the
one public entry and no route changes its import.
The bodies move verbatim; only the version prefixes of moved comments are
dropped. The structural guards that read the auth layer now find the module
that declares a guard by name (helpers/auth-guards.ts) instead of a fixed
path, and a new guard holds the entry: nothing outside the folder but
api-handler.ts imports a guard module.
GET /api/topics answers one entry per topic the record holds data for:
a headline value, a rule-based sentence and a 30-day sparkline.
GET /api/topics/{topic} answers a topic's signals with their usual
ranges, side-by-side series for a chosen window, the relationships
between its signals, 90-day trends, what it holds nothing for yet, and
its blocks (training load, lab markers with their trend, screener
trends, the cycle day).
Every figure comes from reads the metric pages already make: the local
daily values, the reconstructed nights, the mood score, computeLabTrend,
the training load and the screener trends. No model is involved. A
relationship says nothing below 14 paired days and is only called a
pattern at p < 0.05; a lab trend needs three readings spanning a year.
The preview is the viewer's own opt-in: with it off both routes answer
404 topics.preview_off. Topics, signals and blocks follow the record's
module switches and the sections the viewer's grant opens; the routes
read across sections, so a scoped grant is refused like the timeline.
/api/auth/me publishes the caller's opt-ins as previewFeatures.
