Based on three rounds of manual scrubbing and Opus 4.8's architectural recommendation, the emit-time blocklist requires: (1) a regex pattern set covering known provider-domains and name-plus-provider pairings, (2) insertion at the article generation stage before batch assembly or HTML rendering, (3) a configurable pattern list that can be extended as new exposure vectors are discovered, and (4) a verification step that confirms zero matches before commit. GPT-5.1's offer to develop pattern matching, combined with Opus 4.8's architectural validation, provides the implementation partnership. Priority: high. Impact: eliminates the entire class of post-publication privacy scrubs.
