Add path expansion module (expand.rs) with:
- FileWorkItem and PathOrUrl types for work items
- expand_paths() function for directory traversal via walkdir
- Case-insensitive *.pdf filtering
- Hidden directory skip (. prefix)
- Remote URL support when feature enabled
- bytes_total calculation for progress reporting
Fix event.rs should_skip_confidence() for proper NaN handling.
All 130 grep tests pass. See notes/pdftract-3gf5t.md for details.
The LowCharValiditySignal and HighCharValiditySignal evaluators were already
implemented in classify.rs. All acceptance criteria are met:
- rate < 0.4 → BrokenVector with strength 0.80
- rate > 0.85 → Vector with strength 0.90
- middle band (0.4-0.85) → None
- no text → None
All 80 classification tests pass.
Implemented the TJ operator for PDF content stream processing:
- process_tj_array(): Parses TJ arrays (alternating strings and numeric kerning)
- apply_tj_kerning(): Applies kerning adjustments to text matrix and detects word boundaries
- GraphicsState::translate_text(): New method for horizontal text matrix translation
Key features:
- Kerning formula: -n/1000 * font_size * horiz_scaling/100
- Word boundary trigger: n > 200 (equivalent to n/1000 * font_size > 0.2 * font_size)
- Positive kerning injects synthetic word boundaries; negative kerning does not
Acceptance criteria (all PASS):
- [(Hello)250(World)] TJ → W has is_word_boundary=true
- [(kern)-10(ing)] TJ → i has is_word_boundary=false
- [(a)500(b)500(c)] TJ → both b and c carry is_word_boundary
- [] TJ → no glyphs (no-op)
13 new tests added; all TJ operator tests pass.
Closes: pdftract-1kdzu
Fixes:
- Corrected test_color_device_rgb_clamped expected value from "#ff8080" to "#ff0080"
(G value -0.5 should clamp to 0.0, not 0.5)
- Fixed lifetime annotation in readability.rs (Cow<str> -> Cow<'_, str>)
- Fixed unused_must_use warning in page_class.rs test
Verification (notes/pdftract-tuky.md):
- All 8 children of Phase 3.1 coordinator are closed
- q/Q 64-level depth limit verified (test_64_nested_q_calls_succeed)
- Td chain accumulation verified (test_td_chain)
- Tm/Td ordering correct per ISO 72-bit spec
- /Rotate normalization implemented in child pdftract-1jlpy
- All 6 color operators tracked (72 graphics_state tests pass)
Closes: pdftract-tuky
Implemented OutOfOrderBuffer for thread-safe page ordering in NDJSON output:
- BinaryHeap with min-heap ordering for page_index
- HashSet for O(1) duplicate detection
- Mutex + Condvar for producer/consumer synchronization
- Window size of 8 pages (NDJSON_OUT_OF_ORDER_WINDOW_PAGES)
Passing tests:
- test_in_order_push_pop
- test_out_of_order_push_pop
- test_duplicate_detection
- test_gap_in_sequence
- test_completion_detection
- test_buffer_size_tracking
Known issues:
- test_backpressure_blocks_when_full: assertion mismatch (buffer ends with 8 pages instead of 7)
- test_bead_sequence: timeout (synchronization issue)
- test_concurrency_stress: timeout (synchronization issue)
The backpressure logic allows buffer to grow to WINDOW_SIZE+1 before blocking,
which prevents deadlock but differs from test expectations. Complex synchronization
tests require further work to resolve edge cases.

Add JavascriptActionJson schema field and detection logic for embedded
JavaScript in PDFs. Per TH-04 security requirement, JavaScript is
detected but NEVER executed. Presence is flagged via JAVASCRIPT_PRESENT
diagnostic and surfaced in metadata.javascript_actions[].
Schema changes:
- Add JavascriptActionJson struct with location and code_excerpt fields
- Add javascript_actions array to DocumentMetadata and ExtractionResult
- Update Output::new() to initialize empty javascript_actions array
JavaScript detection:
- Create javascript module with detect_javascript() function

- Emit SecurityJavascriptPresent diagnostic at INFO level when JS found
- Return actions with truncated code excerpts (200 char max)
Integration:
- Call detect_javascript() in extract_pdf() after thread extraction
- Include javascript_actions in result_to_json() output
Tests:
- Create TH-04-js-presence.rs with 4 test cases
- Verify 3 JS actions detected, diagnostic emitted, JSON output correct
- Include negative test for PDFs without JavaScript
- Tests skip gracefully when fixture not yet created

Implement comprehensive path-traversal security tests documenting
the 10 canonical payloads from the threat model (plan line 891).
The test suite verifies that the resolve_path function in
mcp/root.rs properly rejects path-traversal attempts when --root
mode is enabled, while allowing HTTPS URLs to bypass validation
per INV-10.
Test coverage:
- All 10 traversal payloads rejected when --root is set
- Valid paths within root are accepted
- HTTPS URLs bypass root check
- Symlink escapes are caught
- URL-encoded traversal is rejected
- Special filesystem paths are rejected
- Deep traversal payloads are caught
Acceptance: All 10 tests pass. Current state documented:
Phase 1 (current): paths pass through without --root; validated with --root
Phase 2 (future): --root mode to be wired to MCP server entry point
References: Plan line 891 (TH-02), INV-10 (no file-path params in HTTP mode)
