Root cause of the equivalence review-queue backlog: spec-matcher read
transceivers.wavelengths (text), but the enricher wrote wavelength_tx_nm
(int) — 27,908 rows had the wavelength in the wrong column, and tx_nm
itself defaulted incorrectly to 1310nm in ~22% of disagreements with the
authoritative part-derived value.
sql/131: backfill + sync trigger from wavelength_tx_nm into wavelengths.
sql/132: correct authority (bare-number wavelengths, not tx_nm) + format
normalization + valid promotion on the full spec-matcher gate.
sql/133: one-directional reach-tier substitution (higher reach may satisfy
a lower-reach requirement, never the reverse; ZR/coherent excluded — real
link-budget/receiver-overload risk, not a simple tier comparison). Tagged
as its own status (compatible_superset), not merged into auto_approved.
