description: 'Structured suggestion from an agent (free — no payment required).
Module scope on purpose: with `from __future__ import annotations`,
FastAPI resolves parameter hints via get_type_hints (module globals),
so a closure-local model would degrade to a query param.
LENIENT BY DESIGN (2026-08-19): 29×422 in 48h showed agents sending
free-form categories and flexible pay fields — a feedback channel that
rejects its own well-wishers is a lost-signal machine. Unknown
categories coerce to "other"; payment-willingness accepts the common
field spellings and dollar floats. Never reject; always record.'
