Classifies the package in the LUX Loom marketplace — the catalog anchor and,
optionally, its commerce reference (the marketplace descriptor,
[[LOOM_MODULE_DESCRIPTOR]]; buildbook WV-MKT-A-01 / WV-CMD-B-02).
Declared on the Module (the one container that holds an app or a
library — a library is a first-class marketplace product). Exactly one
#[Category] per package: the marketplace listing is per-package, so the
extractor errors on a second one.
-
$path — a domain/capability coordinate from the closed LUX taxonomy
(the 13-domain catalogue, WV-LP-A-02). Emitted as an opaque string in
0.18.x; taxonomy validation wires in with the taxonomy master.
-
$sku — the commerce reference id only (a string). Price, currency,
terms and grant are the private marketplace↔vendor contract, resolved at
read time — never in source ([[feedback_benefits_not_prices]]). Folds in
the retired standalone #[SKU] (decided 2026-07-17).
