The route keeps authentication, the slice refusal, the summaries slice, the
cache read and the headers. buildAnalyticsResponse (446 lines) moves to
lib/analytics/response/default-body.ts and calls one module per block, in
its old order: the blood-pressure in-target windows, the glucose summaries
and clinical panel, the correlation hypotheses with their stored patterns,
the Health Score with its Rest Mode framing, and the sleep stages. The
route falls from 761 to 155 lines.
The parity walk recorded before the move is unchanged; the guards on the
glucose window and the bounded reads follow the code.
