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 0217 created the type as `environment_location_source`; the
datamodel declared `EnvironmentLocationSource` with no `@@map`, so the client
compiled every write against `public."EnvironmentLocationSource"`. Postgres
answered 42704, the upsert rolled the transaction back, and the module sat at
"0 days recorded" from the day it shipped — one enum out of forty-nine, and the
only one without a map.
No migration follows. `prisma migrate diff` against a database built from the
committed migrations reports the enum rename and the `environment_contexts.source`
column rebuild before the map and nothing after it: the database was never the
side that drifted, and renaming a live type to match a datamodel typo would be
the wrong direction.
Two guards, because the two questions are different. The unit guard replays
CREATE TYPE / ALTER TYPE RENAME / DROP TYPE across the migration set and holds
every enum to a type that survives it. The integration guard compares all three
name classes Prisma emits — enum type, table, column — against a real migrated
Postgres, which is the only place a name mismatch is observable at all: it
survives generation, typecheck, and every mocked test untouched.
