What PASS means
PASS means selected pages contain a stable table inside the bounded digital-text operator subset, with no unsupported coverage signal. It is not a complete ISO 32000 validation or an accuracy certificate.
PRIVATE PDF TABLE EXTRACTION
Select pages, correct column boundaries and export exact, formula-safe bytes. Scanned, encrypted, rotated and unsupported PDF surfaces fail closed instead of inventing rows.

LOCAL-FIRST
The engine reads the selected bytes in this browser and has no upload or remote-fetch path. The page may still request its ordinary static application files.
FAIL CLOSED
Encrypted files are BLOCK. Scanned/image-only, rotated, skewed, merged-like, unresolved-font and unsupported stream surfaces return INDETERMINATE.
SPREADSHEET SAFETY
CSV neutralizes leading formula characters. XLSX uses inline string cells and also neutralizes formula-leading strings. Raw extracted values remain visible in the JSON analysis for review.
