tengu_pdf_page_extraction

flag never mined JSON

A Claude Code feature flag, read out of the shipped bundle. No mined inventory carries it: everything below comes from what this site has written about it.

PDF extraction and the retention sweep now receive a storage handle instead of finding one themselves.

Not Anthropic's. This is the line from the earliest changelog entry here that named it, v2.1.224.

The earliest release whose published evidence quoted tengu_pdf_page_extraction was v2.1.224, 7 Aug 2026. That is the oldest release this project wrote about it, so it is a floor on the name's age and not the release that introduced it. It is not a presence reading: which builds carried the name is the table below.

The miner has never read a build containing this name. It is here because a changelog entry of ours names it, which is evidence that it existed and not evidence of which releases carried it. The inventory starts at v2.1.138 and everything older than that was never mined.

Read out of the published npm bundle release by release, and out of Anthropic's own documentation as this site captured it. Nothing on this page is a description anybody here wrote about what the feature flag does. All feature flags.
