pdf-mutation v0.1.0

v0.1.0 | Initial Release

Initial release of pdf-mutation, a deterministic glyph-preserving PDF text
replacement CLI.

Added

• pdf-glyph-replace console command and direct pdf_glyph_replace.py script.
• Exact replacement for same decoded glyph counts.
• Support for hexadecimal <...> Tj text and simple [...] TJ arrays.
• Support for multiple CIDs inside a single hexadecimal string operand.
• --align right for simple right-aligned, one-glyph-per-line amount edits.
• --align left for simple length-changing edits that preserve the original
  text matrix.
• --dry-run and --dry-run --json feasibility reports.
• --report non-sensitive JSON mutation reports.
• Synthetic QDF unit tests that do not depend on private PDF fixtures.
• Repo-local policy, roadmap, release metadata, and validation docs.

Known Limits

• Replacement characters must already exist in the active PDF font CMap.
• Matches must fit inside one BT ... ET text object.
• Length-changing alignment modes require one-glyph-per-line hexadecimal Tj
  text with deterministic Td advances.
• The tool does not synthesize fonts, OCR text, redraw pages, edit encrypted
  PDFs, or reflow arbitrary paragraphs.
