A CSV import of a continuous-sensor export wrote nothing and rendered a
green success state. Three faults compounded, and the reporter took all
three apart before filing.
The parser refused every BLOOD_GLUCOSE row with a blank glucoseContext.
Behind it, the CHECK constraint from migration 0021 read both ways at
once: a glucose row MUST carry a context, every other type MUST NOT. The
second half is right and stays. The first was written when the only
glucose writer was the entry form, where a person picks fasting or
post-meal at the moment of the reading. Every machine writer that
arrived since has no such answer per sample, so the Nightscout pull, the
MCP log tool, the Telegram capture and both bulk importers were all
building rows the database then refused.
A missing context now stores as NULL, never as a fifth enum member.
Every per-context reader selects by equality against the four members,
so the reading stays out of the doctor report's fasting rows, the
matching FHIR observations and the per-context targets, while the chart,
the all-time summary and the clinical panel keep it in full. Hand entry
still asks for a context, because at that moment you know it.
The import cards now read the counts rather than the status code.
Nothing written is a failure, a mixed file is a warning, and the refused
rows are grouped by reason with a count instead of fifty identical
lines, with the per-line detail one disclosure away. Both cards render
through one outcome table, so a tick cannot reach a result that wrote
nothing.

One-shot prettier pass so the new format:check gate starts from a clean
baseline. Formatting only — no behaviour change. Generator-owned and
vendored artifacts stay untouched via .prettierignore.
A self-hoster migrating from a spreadsheet or a meter export overwhelmingly
has CSV, which neither the JSON nor the Apple Health import covers. Add
`POST /api/import/csv` reusing the existing write loop and rollup re-fold.
The documented header is `type,value,unit,measuredAt[,glucoseContext,notes,
externalId]`, order-independent. measuredAt must carry an explicit ISO-8601
offset — a row without one is skipped rather than guessed — and is bounded by
the shared entry-instant validator. Glucose accepts mmol/L (converted to
canonical mg/dL) and weight accepts lb (converted to kg); any other
non-canonical unit is skipped, never mis-stored. An optional externalId
column makes a re-upload idempotent; without it a re-upload duplicates.
The response carries a per-row status envelope so a 2000-row file with three
bad rows imports 1997 and names the three. `?dryRun=1` validates and previews
the outcome without writing. The parse, validation, and unit conversion live
in a pure module so they are unit-tested without a database.
Settings -> Export & Import gains a third CSV card mirroring the JSON and
Apple Health cards, with upload, paste, preview, and a downloadable example.
The new route is documented in the OpenAPI contract.
