Defensive Theater Integrity Review

Problem/Feature Description

The team added an optional PDF parser dependency so document indexing can continue even when the dependency is unavailable. Review the implementation for integrity issues. Distinguish legitimate fallback behavior from defensive theater.

Output Specification
