The six /api/auth/me scalar writes (unit preference, glucose unit,
automatic document reading, local lab OCR, workout routes, the central
Codex switch) read their body through safeJson with a 1 KB cap, so each
answers 415 for a body that is not JSON by content type and 400 for one
that does not parse, beside the 413 they already declared. Their
descriptions said so and the responses did not. All three now come from
one block.
The modules and disable-coach route tests had been skipping the
contract check over a 400 and a 409 the registry already declares; the
skips are gone.
Fourteen route tests for the /api/auth/me preference family replaced Prisma
with a mock and asserted the calls it received. Their claims are now shown
through the real handler on the stored row and the response: validation
refusals with their codes, normalisation and defaults on read, optimistic
lock conflicts against a real second writer, rate limits driven to their
first refusal in the Postgres limiter, audit rows read back, cache entries
evicted, and the jobs a change queues observed on a real pg-boss queue.
Assertions that were only about the shape of a Prisma call are replaced by
the behaviour they stood for, and two that described a state only a mock
can reach (a missing column) by the stored value that state resolves to.
