Summary by CodeRabbit

• Bug Fixes
  • Destination and name-tree lookups now compare PDF string names consistently, including names containing non-ASCII bytes or represented with different literal and hexadecimal encodings.
  • Names sharing a common prefix are ordered by their full byte values and length, helping lookups return the correct result for exact limits, ranges, and keys distributed across child nodes.

Walkthrough

Name-tree keys and limits now use COSString values. COSString provides unsigned-byte comparison. Destination lookup paths pass the direct base COSString to the name tree.

Changes: Name-tree lookup

Layer / File(s)	Summary
COSString comparison and name-tree keys src/main/java/org/verapdf/cos/COSString.java, src/main/java/org/verapdf/pd/PDNameTreeNode.java, src/test/java/org/verapdf/pd/PDNameTreeNodeTest.java	COSString adds unsigned-byte comparison. PDNameTreeNode stores keys and limits as COSString values and uses them for name-tree lookup. Tests cover key comparison, limits, encoding equivalence, and child-node lookup.
Destination lookup integration src/main/java/org/verapdf/pd/PDAnnotation.java, src/main/java/org/verapdf/pd/PDDestination.java	Both destination lookup paths pass the direct base COSString to the name-tree lookup.

Priority: Normal

Estimated code review effort: 2 (Simple) | ~12 minutes

Change: Bug fix

Merge Risk: Minimal · up to acb02

Name-tree lookup now preserves byte-based key identity, and the inspected destination paths remain compatible. No actionable merge risk remains after normal checks.

Review comments at @src/main/java/org/verapdf/pd/PDNameTreeNode.java:
- Line 135: Update the leaf lookup in PDNameTreeNode to compare the requested
key against raw COSString keys using byte-by-byte equality, rather than looking
up by key.getString() in the decoded names map. Return the value associated with
the exact byte match.
