A lab runs its own method on its own device, so the window a physician
evaluates a value against is the one printed next to it on that report,
not a catalog band averaged over every lab. Reading a report pulled the
value and dropped that range: the extraction asked for it, the commit
handed it to the biomarker resolver, and the resolver only uses it when
it mints a NEW marker. For every analyte the user already had — the
normal case after a first panel — the printed range was read and then
thrown away.
Add `sourceReferenceLow` / `sourceReferenceHigh` / `sourceReferenceText`
to `LabResult` and carry the range from the report to the reading. The
text is stored whether or not numbers can be read out of it, because
"bis 5,0" and "negativ" state a window too; a range that could not be
parsed is kept verbatim, never replaced with invented bounds.
`resolveEffectiveReferenceRange` is the one place the precedence lives:
the source window wins for that single reading, and the catalog stays
the net for readings without one. A printed string with no derivable
bound does not displace the catalog. Every surface that judges a
reading routes through it — the API verdict, the doctor report, the
insights blocks and per-marker assessment, the coach snapshot, the MCP
read and the FHIR `referenceRange` — so a value cannot read in range on
one surface and out on another.
The API keeps `referenceLow` / `referenceHigh` as the window in force,
so a client that reads only those two renders the right range and the
right verdict with no change of its own; the catalog band, the source
window, its origin and a divergence flag ride alongside for clients
that want to show both.
Read side: the chart draws the source window as a second, visually
distinct band with the reading it came from named beneath it, the
reading rows name the printed range and the catalog band where the two
disagree, and the doctor-report PDF prints the report's own string with
a footnote naming the saved range. Entry side: one optional field on
the lab form, folded away until asked for, and the printed range is
editable on the scan review screen.
The range parser covers the notations German and English reports
actually print — two-sided, one-sided, comma or dot decimals, thousands
separators, trailing units — reads units without ever converting them,
and refuses to guess on anything ambiguous.
Two things about the card that shows what changed since the last panel.
The comparison had no expiry. Someone whose newest panel is years old was
still reading "since your last panel" about a draw from another year — not
stale UI state but a stale sentence, and one the app kept repeating on the
overview every day.
The window is a year, applied to the data rather than to a per-user
dismissal. A year because routine panels are commonly drawn annually, so a
shorter window would hide a comparison that is genuinely the newest thing
somebody has for months out of every year, while past a year the wording
cannot be defended at all. Doing it on the data means nothing to
acknowledge, nothing to persist, no housekeeping asked of anyone, and one
answer for every client through the existing absent contract — the card
already un-mounts on it, and so does anything else reading that route.
Verified in both directions over the real endpoint.
The delta on the right was muted at the smaller size, the same typography
as the meta line under the analyte, so it optically hung off that lower
line and the row read as bottom-aligned even though it measures centred to
the pixel at every width. A delta is the number the row exists to report,
so it takes the content tier, and the cell states its own centring rather
than inheriting it.
The existing cases pinned their clock at the same time: fixed fixture days
against a relative window is a test that passes until a date in the future
and then fails for reasons unrelated to the code.
The hero line said a pulse was well above its 30-day average today. Nothing
had measured a pulse for five days. The day-signals card flagged the same
reading, and the baseline-drift card said the value was above the usual range,
present tense, on a day that held no reading at all.
One class, and it sits in the data preparation rather than in any of the
sentences. Each surface was handed "the freshest stored value" with no notion
of when it was taken, so each of them assumed now. The age was reachable — the
aggregates carry `newestDaysAgo` inside their coverage object — but it read as
a statistics footnote rather than as the fact that governs the tense of every
sentence about the metric, and none of the three consulted it.
A reading is material for a claim about today when it comes from today or from
yesterday. One day rather than zero: a vital taken at 23:40 and read at 00:10
is the same reading it was half an hour earlier. Two is not, because by then a
whole day has passed with nothing in it and the sentence would be describing a
gap.
The rule now lives beside the data. The vital deviations carry the age of the
reading they were computed from, and the two deterministic consumers apply it:
the day-signals flag counts only current vitals toward its count, and the
baseline-drift card surfaces only current deviations. Stale vitals stay in the
list with their age, so the anatomy view still shows them and nothing silently
disappears; the dated level shifts were never today claims and are untouched.
For the narrated surfaces the same fact is stamped onto every metric block of
the Coach snapshot before anything reads it, so the age travels with the
numbers into the hero, the briefing, the Coach reply and the retrieval tools
instead of each of them guessing. A block narrated off a stale series also
lands in the wide event, which is where it should have been visible all along.
An owner can now narrow a grant to the parts of their record they mean to
share, and can offer the third level. Both decisions are made once, on the
invitation, and neither widens afterwards.
The invite schema takes `scope`: absent or null is the entire record, which
is what every stored grant means and what an owner who does not narrow still
gets. An empty array, a key outside the vocabulary and the whole-record
sentinel are each refused with a 422 naming the field; `inviteGrant` refuses
the same three underneath, and its `invalid_scope` now has an HTTP mapping
instead of falling into the generic refusal.
Offering MANAGE asks for a fresh second factor when the account has one. That
gate resolves through the session cookie and has no Bearer fall-through, so a
token caller is refused first with `sharing.invite.manage_browser_only` rather
than being told it is not authenticated by a route that had just
authenticated it. The consequence is deliberate: management of a health
record is offered from a browser.
The account payload gains `sections` and `level` beside `access` and
`canWrite`, resolved server-side and ordered as the consent screen reads.
`access` was `grant.access === "WRITE" ? "write" : "read"`, which would have
published a grant that can delete entries as read-only; it is a total map
now, so the next level cannot ship silent. The capabilities hook carries both
facts and turns neither into an affordance yet — the edit and delete controls
come back in the release where the routes behind them answer.
The consent surface asks two questions in order rather than laying out a
nineteen-cell grid. The level is three radios, narrowest preselected. What
they can open is two radios, the entire record preselected, and only the
narrow branch expands the eight sections with a sentence each. Both honest
limits are stated above the checkboxes, where the decision is being made: a
section shares everything written in it, and the cross-record surfaces do not
appear for a narrowed grant. Documents carries its own warning, cycle appears
only for an owner who tracks it, and Manage collapses the question to the one
line that answers it.
The Manage sentence says the other person can add, change and remove entries,
including ones the owner entered themselves, and says in the same breath what
it does not reach. The acceptance side gets its own responsibility line rather
than the write one wearing a stronger adjective.
Six locales.
Nine surfaces offered a delegate an action the server declines, and the
switch had never been asked about any of them.
The Today rail's dismiss and the coach check-in's keep / let-go write
through routes that resolve the caller, so both refuse under a switch;
they now ask canManage and are absent at either grant level. A priority
action with no href and no handler is no longer rendered as an inert
button at all — the type carries that rule now.
The Vorsorge dashboard card offered the mark-done that /checkups already
withholds, and the checkups list branch inlined its own ungated copy of
the button the cards branch gates, so which view a browser last chose
decided whether the action appeared. Both bind canManage.
The chart overlay cog persists through a route that resolves the caller
and stores a preference belonging to the person rather than the record.
Gated once in the control so the three chart wrappers cannot drift.
Three query parameters opened sheets past a gated button: ?add=<TYPE> on
measurements, ?new=1 on medications, and ?edit=1 on a medication detail,
the last of which opens a wizard refused at both levels. A deep link is
the same affordance as the control that produces it.
The efficacy retarget dial rewrites a setting the owner chose. The
episode documents card offered a link and an upload the vault gates on
the same endpoint throughout. And the dose ledger built its own success
toast, missing both the Undo suppression and the "saved to" receipt its
two siblings already carry — the one a delegate met on every dose.
The Coach drawer is not mounted inside a shared record, so every button
calling askCoach() opened nothing. The launch provider now publishes no
value there and each entry point's existing null check does the rest;
the documents sheet, the one that rendered without checking, now checks.
The briefing payload states how far off a checkup is as a bare number the
model narrates back: "due in N days", "overdue by N days". It got that
number by dividing the hour gap by twenty-four, which answers a different
question than the one the sentence asks. A checkup booked for nine this
morning came out "overdue by 0 days" by the evening. One due Sunday at
01:00, read late on Friday, came out one day off — Saturday, on a calendar
where it is two. A clock-change day is twenty-three or twenty-five hours
long and rounded whichever way its length pushed it.
The checkup screens had exactly this and it was fixed there, so the counting
already exists. Lift it out as `calendarDaysUntil` and have both the phrase
and the number come off it, rather than leaving the payload with a second
body that can drift again. It counts by differencing two integer day indices
read on the person's profile clock, so the answer is exact rather than
rounded, and `extractFeatures` resolves that zone and hands it down — the
number now agrees with the screen the person is looking at.
Today's checkup moves off the overdue list, where the hour gap had put it as
soon as its appointment time passed. The hour it was booked for may be
behind, but the day it belongs to is not.
The horizon that bounds the read stays an hour cutoff on purpose. It is a
query bound, not a statement to anyone about which day something falls on.
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 tag crosstab already ran a with-versus-without Welch test per structured
tag, with a D to D+1 pairing mode whose stated example was an evening tag
against next-day recovery. It only ever had one channel at that lag, and a
recovery score is a wearable composite plenty of accounts never record. The
rated-factor board next to it has tested next-day resting heart rate and HRV
since v1.14.0, but a rated factor is a continuous score, so a binary tag never
reached either vital.
Add both to the tag map. Same engine, same per-side day floors, same
Benjamini-Hochberg family, same card. The fetch filter derives from the map, so
the channels come along without a second query.
The delta read-out goes neutral to match the rated-factor board: with resting
heart rate on the board, a positive delta is worse on one row and better on the
next, and a green plus sign would claim a verdict the association cannot carry.
Refs #616
The profile validator has accepted MALE, FEMALE and OTHER for a long
time, but the published contract documented two, and a client written
against that contract had no way to know the third existed. The profile
PATCH is one write, so a rejected gender took every sibling field with
it - a time-format change lost to a field the person never touched.
Gender now clears on an empty string, the same contract every other
profile field documents, and an unsupported value is refused with a
message that names the field and its accepted values instead of the
validator's own prose. Onboarding validated against a narrower enum
than the profile schema and 422'd the whole submission; its form could
not record the third value at all.
The rest is the same defect in other clothes. The Strain model scored
an unanswered or OTHER account on the male Banister coefficients; it
now uses the midpoint of both published models, matching every other
sex-split formula here. The dashboard snapshot emitted null for an
account that answered OTHER, which is indistinguishable from no answer.
Three casts asserted a two-value type over a three-value column. All of
them now carry the stored value and narrow once, at the boundary of a
reference table that genuinely has no third row, through one named
helper in src/lib/profile/sex.ts.
Refs #645
Add interleaved-writer, tokenless-compat, and malformed-token coverage for the
notification-prefs, modules, coach-prefs, and mood-tag-layout write guards,
including the notification-prefs case where a stale web write must not revert
the app-managed medication flag. Pin the inventory PATCH and DELETE routing
through the advisory lock, and cover the insight-generation privacy re-check on
both the main commit and the reroll arm.
Compliance card: a dose-change imperative and a fabricated risk figure are
withheld to the deterministic fallback (no model text persisted, updatedAt
stays null), while a clean grounded summary still renders and persists.
Hero lines: a well-formed, truncated, or fenced JSON envelope resolves to the
deterministic lead/template for both the arrival reaction and the coach nudge;
a plain-text line still ships verbatim.
Berlin boundary pairs (previously dropped), the gone New York lag-1
offset, all three metric partners moving, UTC-user invariance, and a
metric-by-metric guard proving the weight x BP and BP-medication joins
stay byte-identical across timezones. Update the mocked aggregates for
the additive weightRawRows field and pin the widened raw pull in the
aggregator test.
A truncated or malformed { "summary": "..." } envelope fell through the
status-card parser and rendered raw — braces, the summary property name,
quotes, and literal \n — in the Assessment card (resting pulse and the
other per-metric cards). parseSummaryFromContent returned the raw content
on any JSON parse failure, and a truncated envelope with no closing brace
also fell into that path, so partial structured output reached the reader.
Split the read into extractAssessmentSummary, which classifies a completion
as a parsed summary, genuine prose, or an unparseable structured envelope.
A payload that opened like a JSON object but failed to parse (or parsed
without a usable summary) resolves to the controlled fallback rather than
raw text; plain prose that merely contains a brace is still preserved.
finalizeStatusSummary withholds an unparseable envelope so every status
card serves its deterministic stub, and the two direct callers
(medication compliance, derived-score assessment) get the same guard.
Refs #608
Merge the eight reviewed audit fixes that were cut a week ago and never
landed. Main has moved on since, so each fix was re-checked against the
current tree and each of the five conflicts resolved by understanding
both sides.
Kept, still open on main:
- Proxy early exits now carry the transport security header subset via a
shared helper. Reconciled with main's /api/health worker-only carve-out.
- Batch measurement ingest bounds the entry instant so a future-dated row
can no longer win "latest reading" or poison the rollup buckets.
- Web Push dials through the pinned safeFetch dispatcher with
requirePublicHost, closing the last user-controlled-host egress.
- Mood bulk upsert and its tag/factor links run in one transaction, so a
rejected rating rolls the mood row back instead of leaving a tagless row.
- Full backup carries NutrientIntakeDay with its unit and source. Folded
into main's portable-export / disaster-recovery split.
- Live daily-series fallback restores the min/max spread band the tiered
read already emitted.
- Coach stream aborts its in-flight reader on unmount and resets send state
on a conversation switch.
- Manual water writes share the day-bound helper, nutrient add clamps after
the increment, and the thiamin cap drops to a real supplement ceiling.
- Compliance point window widens symmetrically instead of wrapping overnight.
- Oura, Polar and Fitbit token helpers classify an empty or non-JSON 2xx
body as a handled transient error.
- WebAuthn relying-party fallback to localhost is gated to development.
- Chart-token strip list is derived from the allowlist and pinned by a test.
- Regression tests pin the snapshot-cache tenant key, the GlitchTip
path-secret redaction and the Withings credentials delete.
Superseded by main, tests re-pointed at the current shape:
- The intake CSV import was rewritten on main to run through a background
job with a single-active-job admission gate. The future-date bound is
re-applied at request validation and the per-user limiter is kept for
parity with the bulk twin; the old synchronous-write test is replaced.
Four suites, each mutation-checked against a reverted protection:
- route-workout-scope: the workout row is read exactly once across a ten-turn
conversation that keeps sending the id, the where clause always names
userId, another user's id resolves to nothing and the chat proceeds, and
the section sits inside the health-data fence.
- workout-evidence: the numbers-only closure. An instruction-shaped
sport_type — reachable through the restore path, which types the column as
free text — folds to "other" and never reaches the block; a free-text leaf
at any depth throws.
- page-launch-params: an unknown ?scope= is ignored silently, and ?workout=
yields to both ?c= and the fenced ?doc= path.
- composite-score-anatomy-coach: every score sheet carries an opener, a
scope narrowed to the composite's inputs, and auto-send.
resolveLaunchState's shape assertion gains the workoutId field.
The proxy's seven early exits — worker-only 503, two legacy 301s, the demo-mode
403, and the login / onboarding / MFA redirects — returned before the security
header block, so they carried no HSTS, no framing refusal and no nosniff. Factor
the transport subset into a helper and apply it on every exit. The per-route CSP
stays where it is; it is nonce-bound and only meaningful for a response with a
body.
The WebAuthn relying-party candidate list always carried http://localhost:3000,
including in production. The signed rpIdHash still pinned the real domain, so
this was never a reachable bypass, but a configured production origin has no
reason to carry it. Gate the fallback on development, keeping it when nothing is
configured so getRpId() still resolves.
ORPHAN_ENUMS was a hand-maintained literal that drifted every time
ALLOWED_CHART_TOKENS grew — eighteen allowlisted metrics had no strip entry, so
a model writing 'Your PHQ9_SCORE is elevated' leaked the raw enum into rendered
prose. Derive it from the allowlist and pin the coupling with a test.
The no-signal floors were the coldest text the product renders. They run when
there is nothing to ground against, and they opened on a bare order — "Measure
blood pressure at rest and under comparable conditions", "Evaluate mood trends
over several weeks" — so the one moment the surface has nothing to say was also
the one moment it told the reader what to do.
They now open on what the surface can honestly say: no assessment is available
right now. That is the meaning-first opening for this case, and it is the only
one available, because a floor with no signal may not imply a read. What
follows describes how the measure behaves rather than ordering the reader
around. The signal-grounded lines above them are unchanged.
The prompt version bump re-fingerprints the assessments cached under the old
biomarker prompt; the per-card input hash folds the constant in, so the
regeneration is one-time and paced by the nightly warm.
Pin the four guarantees at the new chokepoint and at both call sites: spend
lands on the ledger, over-cap is refused before any egress, a BYOK chain is
measured against the user-plan ceiling rather than the operator's, and a
failed call refunds in full. Also pin the ordering the consent gate depends
on — a consent-blocked user is never charged.
The fixture described a clean resting series but supplied rows for only
twenty of the thirty days it fed PULSE for. Now that the resolver merges
per day, the ten resting-free days are estimated from their own readings
— and on a day whose only readings are a 150 bpm workout the honest
estimate falls outside the band. Match the spans so the case tests what
its name claims; gap-day behaviour is pinned in resting-pulse.test.ts.
The status tier funnels every generation through runStatusCompletion, which
reserves against the day's ledger before egress and reconciles after. The
comprehensive briefing did not: the shared generator and the on-demand
POST /api/insights/generate route both called the provider chain directly, so
none of that spend reached coach_usage and no daily ceiling applied to it.
Route every briefing provider call — first pass, JSON-shape retry,
grounding-correction retry, and the daily paragraph re-roll — through one
chokepoint that reuses reserveBudget / reconcileSpend and resolveDailyCap. The
reservation lands after the consent gate, so a consent-blocked user is never
charged, and a failed or timed-out call is refunded in full.
Over-cap is a typed skipped outcome for the off-request generator (no upstream
fault to retry against, so no failure marker and no retry enqueue) and a 429
for the on-demand route.
The red-team corpus probed only user messages and model replies. Neither is
the channel that reaches the prompt unguarded: a lab analyte, panel or unit
name, or a medication label, none of which the account holder authors when
the row was committed from an uploaded document.
The free-text guard's file list was hardcoded and had rotted — three of its
four entries were no longer reachable from the snapshot, and it covered one
of the dozen files that actually emit free text, which is why the lab fields
went unnoticed. Derive it from the import graph instead; it now covers 75
files, with a floor assertion so a resolver break cannot silently empty it.
Deriving the list immediately surfaced a second leak: features.ts shipped a
raw medication name and dose into the snapshot medications block.
Also fix sanitizeForPrompt itself. It deleted control characters, which
welded neighbouring tokens together and destroyed the word boundary its own
injection patterns anchor on, so a payload preceded by a newline survived
because of the newline. Replace with a space and collapse before matching.
The status-provider suite drives the real budget module against an
in-memory stand-in for the day's usage row, so it exercises the atomic
reserve/reconcile path rather than asserting a mock was called: spend
lands on the ledger, an exhausted day is refused before any egress, a
failed generation is refunded, and a chain on the user's own key is
measured against the user-plan ceiling rather than the operator's.
The snapshot suite walks a 60-turn conversation and pins the full
snapshot to exactly two turns — the first and the elision crossing —
including the case where a lost reply shifts the turn parity.
The coverage check hung off generateInsight, whose only caller runWithFallback
has no production caller left -- every live surface routes through
runRawCompletionWithFallback instead. The admin quality dashboard was reading a
metric nothing emitted. Widen the input to the structural shape both payloads
share and call it from the comprehensive post-parse step, so the annotation
reflects real generations.
Writing the locale tests found three gaps the English-only banks hid: Polish
verb suffixes fell outside the ASCII word class, a trailing word boundary after
an accented character never closed, and German subordinate clauses put the verb
last so the natural phrasing of a dose instruction never matched. The payload
collector also skipped legacy bare-string recommendations entirely.
Covers the assertion that would have caught the narrowing: normalizeLocale
passes all six locales through and defaults an unknown value to English, the
de/en cache keys stay byte-identical while the four widened locales get their
own, and a fr locale entering a status generator reaches the prompt builder
as fr and writes the fr cache row. The forced-warm case pins the same for the
comprehensive and per-status warms.
The generated-insight narrative layer built its user-facing sentences by
string interpolation and never routed through the i18n bundle, so a
non-English UI rendered English text spliced into localised copy — e.g.
"Higher activity steps tends to go with lower next-day weight" surfacing
mid-German on the Weight insight. Because those strings bypassed t(), the
locale-integrity guard could not catch them.
Route every correlation narrative through the server translator:
- Correlation discovery (daily lagged pairs + labs-vs-outcome) now takes
the reader's locale, resolved from the correlations route the same way
other insight generators resolve it. Sentence templates, the direction
word, and every channel label live under a new insights.correlation.*
namespace, translated in de/en/es/fr/it/pl. The three fixed hypotheses
(BP-compliance, mood-pulse, weight-weekday) and their weekday labels are
localised the same way; the analytics cache key now includes the locale
so a language switch cannot serve another locale's cached text.
- Metric labels resolve to stable localised channel labels; the never-
causal framing ("not a cause" / "an association, never a cause") and the
faint/moderate/high hedging tiers are preserved in every language.
English output is byte-for-byte unchanged. Adds a regression test pinning
German narration and asserting it is not the English string.

Claude-Session: https://claude.ai/code/session_018V8V9qapgHi7fhgtMJ8SkM
The eleven per-metric/derived-score status helpers (pulse, weight,
bmi, mood, blood-pressure, medication-compliance, general, the generic
metric card, biomarker, the shared feature cache, the derived-score AI
warm layer) computed todayKey from toBerlinDayKey(new Date()) before
resolving the user's own timezone — several fetched the profile only
for downstream day-bucketing, after the cache read had already run on
the Berlin key. A non-Berlin user's card regenerated at their local
evening (Berlin midnight) and, for biomarker series and the
derived-score prompt label, mis-keyed data or displayed a hardcoded
"(Europe/Berlin)" regardless of their actual zone.
Threads resolveUserTimezone()/userDayKey() ahead of every cache read
so the day-key and the data bucketing agree, and reuses the one
resolved value everywhere downstream instead of re-deriving it.
The asc+take(20000) window-cap bug (fixed on the correlations route
alone) and the mixed-grain toDailyMeans bug (fixed on three of four
readers) both survived on the Coach get_correlations tool, the
per-metric assessment card, and the period narrative. Dense accounts
saw the cap drop the newest rows on the coach/card readers and drop
the CURRENT period on the narrative — backwards for a recent-window
and a current-vs-prior surface respectively; the narrative's own local
toDailyMeans twin also averaged sleep stage-segments and blended
per-sample step chunks with drained daily totals instead of summing.
Hoists the fetch + grain resolution into
fetchMeasurementWindowSeries/fetchMoodWindowSeries
(correlation-channel-series.ts) — desc+cap+resort, full column select
for buildMeasurementDailySeries's per-type grain — and routes the
route, the coach tool, the per-metric card, and the period narrative
through it, deleting every local copy.
Four data-correctness fixes in the same class as the workouts-list
ordering bug (05f80ad37):
- GET /api/measurements groupBy=day: the raw-row scan ordered oldest
first and sliced to `limit` before bucketing, so a long history never
surfaced its recent days. Reads newest-first now. The per-day sum
also ran over every source unfiltered — an Apple Health + Withings
write for the same day doubled the total. Routes through
pickCanonicalSourceRows first, matching the rollup tile's collapse.
- PR detection's cumulative-day picker summed every row on a calendar
day regardless of source (false "record" days) and bucketed on the
UTC calendar day instead of the user's timezone. Rewritten to
source-collapse before summing and bucket on the user's IANA zone,
reading through the worker's injected Prisma client so the existing
dependency-injection contract for tests stays intact.
- The correlation-discovery matrix (the insights route, the per-metric
assessment card, and the Coach's get_correlations tool — three
independent copies of the same fetch) averaged cumulative types
(steps, daylight) and sleep across mismatched grains: per-sample
chunk means blended with drained daily totals, and sleep averaged
per-stage segment durations instead of summing a night's total.
Hoisted the grain resolution into one shared
buildMeasurementDailySeries helper (source-collapsed day-sum for
cumulative types, per-night reconstruction for sleep, mean
unchanged for spot vitals) so all three surfaces agree.
Regression tests cover newest-first ordering, cross-source collapse
matching the rollup, PR no-double-count, and the shared grain helper.
Fold the ECG silo into the insights narrative without crossing the
non-diagnostic line — the app reports the recording device's own verdict
and the existence/count of recordings, never an interpretation of the trace.
- Feature snapshot: a bounded, device-verdict-only ECG descriptor (recording
count, device-verdict distribution, latest recorded-days-ago + average HR)
flows into the nightly briefing prompt. The waveform never enters the
payload; the grounding gate admits the pre-computed counts so a
device-attributed sentence stays grounded. A prompt rule (EN + DE)
constrains any mention to the device's attribution and forbids reading
morphology, measuring intervals, or emitting a verdict of the app's own.
- Pulse cross-link: a device-attributed pointer from the resting-HR / pulse
page into the ECG viewer, un-mounting when no recordings exist.
- Daily rail: an ecg_new_recording item surfaces once when a recording landed
within the last day — calm, info-level, deep-linking the viewer. Gated on
the insights module; the DTO carries no waveform.
- i18n across all six locales; non-diagnostic disclaimer copy per language.
"Ask the Coach" on a document used to navigate to /coach?doc=<id> — a full-page
jump away from the vault. It now opens the real, doc-scoped conversation in the
shared side drawer, and the drawer's maximize control expands it to the full
/coach page while preserving scope.
- Thread an optional documentId through the launch context: askCoach gains a
fourth argument, the provider tracks it alongside prefill/scope and clears it
on close, and LayoutCoachMount forwards it to the drawer as initialDocumentId.
The open-state precedence moves into a pure resolveLaunchState helper.
- The vault detail sheet closes itself and calls askCoach(..., doc.id) instead
of routing away, so the drawer owns the surface.
- Maximize preserves continuity: the drawer reads the live conversation id via
a new imperative getter out of the conversation surface (parallel to the
reset registration) and hands off to /coach?c=<id> once a thread exists,
falling back to /coach?doc=<id> for a chat maximized before its first turn.
The send path is untouched: every document turn still routes through the
hardened fenced endpoint keyed on documentId — only where the conversation
renders (drawer vs page) changed. The documents-chat e2e now asserts the
drawer opens in place, doc-scoped, rather than a URL change.
ECG recordings synced from a compatible watch were stored encrypted but
shown nowhere. They now have a surface in Insights: a list of recordings,
each opening the full single-lead waveform on a familiar ECG grid, with the
date, duration, average heart rate, and the result the device recorded.
The read routes narrow ownership in the query and decrypt the waveform
through the existing fail-closed codec; the overview is min/max-decimated so
the R-wave peaks survive the reduction, with a raw path for a calibrated
view. The result shown is the recording device's own classification,
attributed to the device — HealthLog does not read or interpret the trace
and produces no verdict of its own. A permanent note states this, and a
non-normal result carries a line to discuss the recording with a clinician.
Deferred perf fixes from the campaign's verified perf-correctness audit,
correctness-first (each with an output-equivalence test):
- comprehensive-generate fan-out: replaced per-type 400d findMany+JS-average
with DB prisma.aggregate(_avg) over the exact half-open windows the JS
reducer used (current 30d, lastMonth (60d,30d], lastYear (395d,365d]), same
rounding + null-on-empty, pLimit(4). SLEEP_DURATION stays on the raw path
(per-night reconstruction dedup). Byte-equality test vs the old algorithm.
- boot-discovery: replaced Prisma in-memory distinct with DB SELECT DISTINCT
in the 4 backfill discovery scans + migration 0243 (7 additive
partial indexes matching each predicate). Integration test asserts identical
discovered set against real Postgres.
- ChatBubble wrapped in React.memo with a comparator (onRegenerate compared by
presence — the thread rebuilds it each render), so only the streaming bubble
re-renders per token.
- doctor-report mood read narrowed to {score, tags} (the only fields the
collector uses); the 730d main measurement read left as-is — a blind bound
would corrupt clinical stats (documented deferred follow-up).
Migration 0243 additive-only.
The per-metric insight assessments opened on the current value and read as
a data readout, while the overview texts lead with the day's verdict and
land the warm, motivating tone. Diagnosis (campaign insights-copy audit +
verification): identical warm persona/contract fragments, but the
per-metric USER prompt instructed number-first while the overview
instructed verdict-first, and the opener-hint rotation was wired into
briefing/scores/Coach but never the per-metric path (so the base prompt's
'do not open with the number' clause stayed dormant there).
Rewrote the seven per-metric assessment user prompts (generic archetype +
six bespoke: BP/weight/pulse/BMI/mood/compliance + overall) verdict-first
in EN+DE — meaning first, the number right after as support; grounding,
non-diagnostic framing, no-vendor and no-markdown all preserved (only
clause order changed). Wired openerArchetypeHint into metric-status and
the bespoke generators. Factored a shared openingShape contract into
shared-contracts so overview/per-metric/scores can't drift again, with a
coverage test. Lifted the three deterministic first-paint fallbacks to
verdict-led. Prompt-contract regression tests added. No new model calls,
token budget flat.
The recurring no-briefing day had a chain of causes, closed end to end:
Every failure path in the nightly pregenerate + the comprehensive generator
now annotates a queryable cause (several classes — features-error,
payload-too-large, aborted, generator-failed — previously bumped a counter
with zero trace). A failed nightly warm enqueues one bounded retry ~45
minutes later (singleton per user, existing budgets apply), so a transient
provider hiccup heals before morning. A cached payload that carries NO
briefing no longer satisfies the 24h POST short-circuit nor the
unchanged-content hash gate — a once-stripped briefing could previously
block its own regeneration indefinitely. The card surfaces the omission
reason persistently (grounding strip, generation failure, not attempted)
with a forcing retry.
Documentation corrected against code truth: Withings credentials are
per-user (the documented env path never existed; the dead example entries
and manifest rows are gone, and WITHINGS_WEBHOOK_SECRET is now actually
whitelisted in compose — stock deploys could never deliver it); the classic
Fitbit portal no longer accepts new registrations; the backup-restore
example no longer mints a fresh encryption key and uses pnpm dlx tsx; the
TLS guide describes the real client model (two CA-level SPKI pins,
any-match, leaf renewals need no build); scaling/admin references fixed;
the operator-shared subscription provider is documented.
Platform-wide hardening: the failure classes found live this week hunted down
across every integration.
Fitbit carried the same tombstone wedge fixed for Google — probe now matches
soft-deleted rows and the update resurrects them; the comment describing a
partial unique index that never existed is corrected. Sleep segment ids are
stable across re-scoring for Withings (session+segment-start), WHOOP/Polar
(one segment per stage, no positional index) and Oura (run-start keyed), each
with a session-scoped sweep that soft-deletes rows a re-score orphaned — so
legacy and affected nights heal as they are re-read.
One platform rule for deleted rows: source-owned readings resurrect on
re-import (Withings, WHOOP, Oura, Polar, Nightscout, mood webhook, CSV
re-imports, Apple stats day-totals); Apple sample-grain deletions stick per
the paired-client contract, and the mood bulk route's tombstone match is now
a true no-op reported as duplicate. Import counts reconcile against actual
createMany counts.
Google lifecycle: a dead token registers on the cycle's hard-fail ledger, so
an expired connection parks instead of stamping success hourly; backfill and
sleep-repair markers stamp only after a clean pass (pg-boss retries are now
real); failed measurement writes hold the watermark; no-op updates are
skipped; mapping.md tells the current truth.
Scale: doctor-report reads only consumed columns and enabled sections;
exports and backups keyset-paginate; achievements tally via SQL buckets;
series charts day-bucket dense kinds beyond 90 days; BP pairing is a linear
two-pointer; distinct-type scans run server-side; the graded-series cold
fallback is bounded; the fitbit defer tracker loops instead of spreading.
The comprehensive briefing warm/cron path wrapped generation in a fixed
130 s outer abort, but the per-user response-timeout setting accepts
10-600 s and the AI settings tell users to raise it for slow local
models. Any account whose response timeout was >= ~130 s had every
comprehensive warm clipped by the warm bound, not the provider, so the
generation never landed: no cached briefing row was written and the
dashboard fell to the hard empty state.
Size the warm outer abort from the resolved effective timeout
(`aiResponseTimeoutSeconds * 1000`, falling back to the comprehensive
surface budget) plus a fixed headroom for feature extraction, prompt
assembly, and the cache write. A raised setting now extends the warm and
nightly budgets instead of being silently capped. An absolute ceiling
(the 600 s write-time maximum plus the headroom) keeps a wedged call from
pinning the worker while staying above the largest value a user can set.
Both the nightly loop and the forced on-visit warm read the per-user
setting and use the derived budget.
Make the empty state more useful: record the upstream HTTP status on a
failure marker and classify it (timeout / auth / rate-limit / provider /
format), so the "couldn't generate" state points at the right lever —
raise the response timeout for a timeout, re-check the provider for an
auth rejection — instead of one generic line. Keep-last-good behaviour is
unchanged.
Align the response-timeout field copy with the actual default budget
(~120 s, not ~180 s) across the placeholder, the OpenAPI description, and
the inline note.
The insights alert cards computed medication compliance with the naive
`schedules.length × days` denominator, so a fully-adherent weekly
injectable read ~14% and fired a false low-compliance alert (and a paused
medication mis-fired the same way). Route the alert path through the
canonical `calculateCompliance` engine like every other compliance
surface — pause eras, schedule revisions and dose windows honoured.
Document confirm: committing a numeric observation against an existing
biomarker silently replaced the stated unit with the catalog's, with no
conversion — a stated "6.1 mmol/L" against a mg/dL marker committed
"6.1 mg/dL". Reject on a unit mismatch (fail closed) so the user
reconciles on the review screen, the same posture as the unit-required
guard.
Wire grip strength, waist (with waist-to-height) and pain into the
briefing feature set and the grounding allow-set so the clinical-depth
signals reach the daily narrative; the mental-health screeners stay
excluded by construction.
Biomarker detail: fall back to a generic description for catalog-less
markers, and keep the heading + description with a retry on the error
state. Collapse the medication External-API and Lifecycle groups by
default. Re-enable the insights scroll-to-top regression and assert the
shipped main-content reset.
Align the EN haemoglobin/haematocrit display names to British spelling.
Drop the redundant `(userId, deletedAt)` index on inbound documents — a
strict prefix of the new three-column index. Trim the dead
MedicalDisclaimer variants to the one live `dataPosture`. Move the
crisis-resources card off the retired amber tint to a calm
destructive-subtle border. Add a registry invariant asserting every
biomarker signal key resolves to a real catalog slug.
