Critical Drift Events — Required Fields Disappeared

CRITICAL

Product schema lost `offers` on 38 PDPs

3 hours ago: WooCommerce plugin update v8.4.2 stopped emitting offers in Product JSON-LD on 38 PDPs. Rich results at risk within 48 hours. Roll back plugin OR patch via woocommerce_structured_data_product filter immediately.

CRITICAL

Article schema missing `author` on /blog/* (12 pages)

6 hours ago: New blog template deploy removed Person author block. Replaced with string-only. Google requires Person or Organization object. Fix Article schema generator to emit full author object.

CRITICAL

Schema type changed: Recipe → HowTo on /recipes/* (24 pages)

Yesterday: Recipe schema replaced by HowTo. Recipe rich results will disappear. Either restore Recipe type (preferred) or accept HowTo + audit content for HowTo compliance.
