v0.2.0 — editing-depth (encrypted PDFs · CID-keyed CFF · CJK · honesty taxonomy)

Editing-depth release. v0.2.0 widens the set of PDFs the engine can edit faithfully — password-protected documents, CID-keyed CFF/Type1C fonts, and CJK text — and hardens the honesty contract: anything the engine can't do cleanly is now surfaced as a typed Degradation (or refused) instead of silently corrupting output. DegradationKinds: 13 → 30. The public API is backward-compatible.

📦 pip install pdf-edit-engine==0.2.0 — https://pypi.org/project/pdf-edit-engine/0.2.0/

Added

• Edit encrypted PDFs end-to-end — opened, edited, and re-saved with encryption preserved (new password= kwarg); honest encryption_dropped fallback when re-encryption isn't possible.
• CID-keyed CFF / Type1C in-place glyph injection — Identity-H CIDFonts with CFF outlines (not just TrueType glyf) can now be extended; collision-free CID == GID, pre-existing CIDs never renumbered.
• CJK / UAX#14 line-break — a spaceless CJK paragraph wider than its column now wraps at ideograph boundaries instead of silently overflowing; the Latin path is byte-identical.
• ToUnicode recovery — Type0/Identity-H fonts with no /ToUnicode map get their CID→Unicode recovered from the embedded cmap so text is locatable.
• Opt-in shrink-to-fit (fit="shrink") to fit text into a fixed-height region.
• Honesty-taxonomy DX surface — root-level exports (Degradation, DegradationKind, FONT_AFFECTING_KINDS, DEGRADATION_KINDS), FidelityReport.summary() / .is_clean / .max_severity / .warnings(), and EditResult.to_dict().

Fixed — silent corruptions now refused or surfaced

Multi-match same-operator collisions, content deletion (no more eaten neighbours), ligature integrity, rotated-text flattening, and reflow byte-stability — plus color, indent, and declared leading preserved through reflow.

Security

Graphics-state (q/Q) depth cap, font/CMap decompression-bomb guard, and linearization (Fast Web View) preservation on save.
