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.

-- sql/133 — One-directional reach-tier substitution policy
|
|
--
|
|
-- Decision (Rene, 2026-07-07): a higher-reach optic may satisfy a lower-reach
|
|
-- requirement (e.g. a 40km ER can serve where a 10km LR is asked for), never the
|
|
-- reverse — the shorter-reach part cannot close the link budget on a longer run.
|
|
-- ZR/coherent/amplified tiers are explicitly EXCLUDED from this automatic rule:
|
|
-- those can overload a short-haul receiver without an attenuator, which is a real
|
|
-- power-budget calculation, not a simple tier comparison. Those stay in manual review.
|
|
--
|
|
-- Result is tagged as its own status (compatible_superset), never merged into
|
|
-- auto_approved/exact-spec matches, so downstream consumers (Fossy/Beo/Pulso, pricing)
|
|
-- can distinguish "identical spec" from "safe higher-spec substitute" — they usually
|
|
-- differ in price and are not a like-for-like swap.
