How to read a failed retrieval

Recording that we could not read a document is as important as recording what we could read. The source list says which of those happened.

• Redirect. The old brand’s domain now points at a successor. That is not a geo-block. Example: Fortune Coins → Fortune Wins.
• Not attempted. We have not yet located a rules URL. Homepage retrieval is not a blocked official-rules document.
• Blocked or unreadable. We requested a specific rules or help path and the response was a refusal, a geo-block, or a page whose text we could not read. That is dated. It is not a finding that no terms exist.

Sparse operator pages stay indexable because the documented gap is the answer. See Chumba Casino.
