"""D14b wiring: status=auto, search_formulas, and evidence loader skips formula files.

Completes the formula layer beyond the store: the `auto` status the spec requires
(§4.7.2), the concept-substring retrieval that `tht search find --kind formula` uses,
and the guarantee that load_evidence_dir does NOT choke on *.sql.md formula files when
they live under the evidence root.
