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.
The key is a function of the marker's name and unit, but it was only ever
filled, never replaced, so a marker renamed from Glucose to Cholesterol kept
converting readings with the glucose factor. The marker edit now re-derives
it with the same match the creation paths use (clearing it when the new name
matches nothing), and the fill step a reading runs brings a stored key back in
line with the name, so a key written before this fix is corrected the first
time it matters. The scan review derives the key the same way as the commit.
Slice 3 of phase 3 of #1095. The scan review no longer treats every reading in
another unit as unwritable. The server tells it which analyte the matched marker
is (markerAnalyteKey on each extracted row); a row whose unit differs but can be
converted starts selected and carries a badge saying what Save will store and
what the report stated ("Saved as 100.9 mg/dL, converted from 5.6 mmol/L"). A
row that cannot be converted keeps the existing blocked badge and error. Save
still sends what the report printed; the server converts, as in slice 2.
The review's duplicate flag also recognises a re-scan of a reading that was
stored converted, by what the report printed, the same rule the commit applies.
A converted reading carries a quiet "converted from 5.6 mmol/L" on the lab list
(row and tile) and the history list (phone and table), so a number nobody typed
can always be traced back to what the report printed.
Strings in all seven locales.
Refs #1095
A numeric lab reading was stored with its value as received and the marker's
unit stamped on it, so 5.6 mmol/L against a marker kept in mg/dL became
5.6 mg/dL and read as far below range. Both the manual/API write and the
scan commit did this; nothing compared the two units.
- POST /api/labs returns 422 labs.unit.mismatch, with the marker's unit and
the reading's unit in meta, and writes nothing. The unit is compared only
when one was sent: on the biomarkerId path it may be omitted, and the
marker's unit is then the stated one. A qualitative reading has no unit.
- The scan commit skips such a row with reason unit_mismatch, so the outcome
reads partial or failed instead of a clean save, and the toast names the
analytes concerned rather than saying "duplicates".
- The extract response carries the matched marker's unit. The review screen
shows a calm badge on a row in another unit, starts it unticked like a
duplicate, and treats it as a blocking error on the unit field if it is
ticked anyway.
- A small lab-specific normaliser forgives spelling only: spacing, the micro
prefix, the case of the litre, and a unit printed in capitals for a short
list where capitals cannot mean another unit. Case is otherwise significant,
so mIU/L and MIU/L, or g/L and G/L, are never merged.
The document-commit path already refuses a mismatch and is left as it is.
Readings stored wrongly before this cannot be identified, because the
original unit was never kept; they are not touched.
Adds EN and DE strings; the other locales are left to the maintainers. The
OpenAPI spec and the error-code catalogue carry the new code.
Fixes#1094
`instant.toISOString().slice(0, 10)` and parsing a key back as UTC
midnight are the idioms behind every day-boundary fix this year: the
evening west of UTC and the small hours east of it land on the
neighbouring day. A new rule, healthlog/no-utc-day-key, refuses them in
src/ outside src/lib/tz and tests, and refuses a disable directive for
itself that is not next-line or gives no reason.
The time zone module now names every legitimate form: userDayKey for a
person's day, dateOnlyKey / dateOnlyAtNoonUtc / dayKeyAsUtcMidnight for
date-only values and day labels, daysBetweenDateKeys / weekdayOfDateKey /
isCalendarDateKey / statedDateKey for key arithmetic and parsing.
Of the 133 sites the rule found, 84 are gone. Most moved onto a named
helper with no change in behaviour; these changed behaviour:
- cycle calendar, insights, Coach snapshot and prediction refresh start
their lookbacks at the first instant of the user's day
- a model-transcribed date like "June 10, 2026" no longer lands a day
early in a process east of UTC (documents and lab scans)
- a custom report range covers exactly the picked days in the profile
zone instead of starting the evening before west of UTC
- date-of-birth pickers cap at the user's today, not the UTC one
- an allergy onset date is stored at noon UTC like other date-only values
- the report's cycle summary, the Coach's usual BP range and the intake
projector's rollup recompute use the user's day
- vaccination dates render as dates instead of the previous evening
49 remain, each with its reason on the line above: 39 UTC by design (15
file name stamps, rollup and object keys, the UTC-day score engines) and
10 marked baseline. A guard test requires a classified reason on every
directive and holds the baseline to a ceiling that only goes down.
The scan commit and the review screen looked for an existing reading in
the UTC day of the scanned date. A hand-entered morning draw east of UTC
sits on the previous UTC day, so scanning the same report wrote the
reading a second time. Both checks now compare calendar days: a date-only
reading's stated date, or the user's day of a hand-entered instant.
The free-text reference-range parser decided what a printed window meant from
an alternation of German and English words. The app ships six locales, and a
lab prints in the language of the country it stands in, so `jusqu'à 5,0`,
`hasta 5,0`, `fino a 5,0` and `do 5,0` all fell through to `low: null,
high: null`. The string was stored, the reading was then judged against the
biomarker's own band or against nothing at all, and no surface anywhere said
that the lab had printed a window the app could not read.
The vocabulary is TABULATED here, not derived from `messages/<locale>.json`
the way an app-owned word list would be. These words are prose a lab printed
on paper; the app owns no string they could be read out of, and the language
of a report has nothing to do with the language of the UI. So the table is
hand-written, keyed by the shipped `Locale` union so that adding a locale
fails to compile until someone has answered how that language prints a range,
and every locale's words are tried against every input at once. The cost is
written down at the table: a report in a language absent from it stays
text-only.
Three things had to change beside the word lists. Introducing words are now
stripped only on a second pass, because Italian "da", Polish "od" and French
"de" also state a floor on their own and stripping first read "da 3,5" as a
bare number. Input and table are diacritic-folded and their apostrophes
normalised, so a table row written "jusqu'a" meets a report's "jusqu'à" and
the curled apostrophe a word processor emits. And one-letter separators ("a",
"e", "y") are only accepted with whitespace on both sides, so "3.5e5" is not
read as a window. Decimal commas already worked and are pinned by the new
cases.
An unreadable window now has a name. `isUnreadableRange` separates "the report
stated nothing" from "the report stated something nobody could read" — the two
were indistinguishable at every call site, which is what let the French case
pass unnoticed. The manual form already showed the reader that the text was
kept but not read; the two ingest paths now count it into their wide event, so
an unsupported notation surfaces as a number rather than as silence.
The German and English lists are the previous alternation split word for word,
and the existing suite covering them passes unchanged.
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.
Replace the CompletionParams { systemPrompt, userPrompt } string pair with a
structured { system, messages[] } request across all five AI clients. One
refactor unlocks three things: provider prompt-caching (Anthropic cache_control
on the stable system prefix, OpenAI/Codex automatic prefix cache, with
cachedInputTokens surfaced for observability), the tool-calling wire surface,
and clean multi-turn.
Each client maps the new shape to its own wire and degrades unsupported
features silently: the local OpenAI-compatible server never receives a tools
field (most reject unknown keys), and prompt-caching is best-effort everywhere.
CompletionResult gains toolCalls, finishReason and cachedInputTokens; the tool
types and per-provider mapping ship now, the tool-use loop does not.
Vision inputs fold into the user turn's content parts via singleUserTurn, with
each provider's pre-existing block ordering preserved. The corrective-retry
paths append to the last user message rather than a flat string. The Coach
keeps assembling one user turn so its snapshot-once and grounding behaviour is
unchanged. No wire schema visible to API consumers changed.
Behaviour is unchanged across every surface; the full suite stays green.
Add an opt-in in-browser OCR path so a user whose provider cannot read
images (ChatGPT-OAuth/Codex, a text-only model) can still scan a lab
report. The capability probe gains a `mode` field: `vision` when the
provider reads the image directly, `text` when local OCR is enabled and
any provider is configured, or null. The extract route grows a text
branch that accepts the in-browser-OCR'd text as JSON and structures it
through the existing schema + review/commit flow; the raw image never
reaches the server in text mode. New `labsLocalOcrEnabled` user column
(migration 0184, default off) gates it, with a dedicated PATCH endpoint.
Resolve a vision-capable provider, gate with consent + a 6/hour rate bucket +
a reserved per-day token budget, then transcribe an uploaded photo or PDF into
structured proposed rows. The raw upload stays in memory only and is never
persisted. The commit route writes only the rows a human confirmed, resolving
or minting a biomarker per row with source OCR and skipping commit-time
duplicates. The capability probe drives whether the UI shows the scan entry.
Extracted text is treated as untrusted; the review screen is the safety
boundary.
