Implements tests/security/TH-01-stream-bomb.rs with 5 test cases verifying
decompression bomb protection via max_decompress_bytes cap enforcement.
Acceptance criteria PASS:
- tests/security/TH-01-stream-bomb.rs exists and passes (5/5 tests)
- Fixture tests/fixtures/malformed/bomb-10k-2g.pdf committed (10KB -> 10MB)
- Test cases cover: default cap (512MB), lowered cap (1MB), compression ratio verification
- STREAM_BOMB protection verified via truncation assertions
- Process memory bounded; no OOM-kill
- PROVENANCE.md entry added for bomb fixture
Test cases:
1. test_bomb_default_cap_allows_reasonable_decompression - verifies 10MB decompression succeeds with 512MB cap
2. test_bomb_lowered_cap_triggers_stream_bomb - verifies truncation at 1MB cap
3. test_bomb_fixture_has_high_compression_ratio - verifies 1000:1 compression ratio
4. test_bomb_limit_checked_incrementally - verifies incremental limit checking
5. test_bomb_limit_truncation_behavior - verifies decoder returns partial data on limit hit
Fixture generation:
- gen_bomb.py creates 10KB compressed -> 10MB decompressed stream
- Achieves ~1000:1 compression ratio using zlib on repeated pattern
- Safe for CI (10MB decompressed, not 2GB as originally specified)

- Fixed missing fields in BlockJson, SpanJson, ExtractionOptions initializations
- Added feature gates to ocr_integration tests for conditional compilation
- Fixed McpServerState::new calls to include audit writer argument
- Fixed CCITTFaxDecoder::decode calls to use instance method
- Fixed type casts for ObjRef::new calls
- Fixed serde_json::Value method calls (is_some -> !is_null)
- Fixed ProfileType test feature gates
- Worked around lifetime issues in schema roundtrip tests
These changes fix numerous compilation errors that were blocking the
codebase from building. The main library and tests now compile successfully.

Implement TH-07 security test validating that PDF password ingress
channels properly prevent password disclosure via process arg list.
Test cases:
- --password VALUE rejected with exit 64 without opt-in
- --password VALUE with PDFTRACT_INSECURE_CLI_PASSWORD=1 proceeds with warning
- --password-stdin works correctly
- PDFTRACT_PASSWORD env var works correctly
- Password leaks in /proc/<pid>/cmdline under opt-in (proving the vulnerability)
- Password does NOT leak with --password-stdin or env var
Closes: pdftract-43jxa
Add two PDF/A fixtures for testing assisted-OCR (BrokenVector path):
- Aligned fixture with correctly-positioned invisible text layer
- Misaligned fixture with text layer offset by (10pt, 5pt)
Extend ci/wer-gate.sh with WER validation for BrokenVector fixtures.
Acceptance criteria:
- Two BrokenVector fixtures committed (both 1.5 KB, well under 200 KB limit)
- ci/wer-gate.sh extended with new fixture invocations
- WER delta tests will skip gracefully when OCR environment unavailable

Implement the libpdftract native FFI library as a cdylib + staticlib
with cbindgen-generated headers and full extern "C" API.
Components:
- crates/pdftract-libpdftract/ with cdylib + staticlib targets
- All 9 contract methods + utility functions as extern "C"
- cbindgen config and generated pdftract.h header
- pkg-config template (pdftract.pc.in)
- Homebrew formula template (distribution/homebrew/)
- vcpkg port template (distribution/vcpkg/)
- C conformance test (tests/conformance.c)
API features:
- Owned JSON strings returned via CString::into_raw()
- Caller frees with pdftract_free() (not libc free())
- Thread-local error storage (pdftract_last_error)
- Thread-safe and reentrant (no global mutable state)
- ABI version function for compatibility checking
Verification:
- cargo build produces libpdftract.so and libpdftract.a
- Conformance test compiles and runs successfully
- Thread safety verified with 4 concurrent threads

The Crypt filter was already implemented in the codebase. This note
documents the verification of acceptance criteria and test coverage.
Acceptance criteria verified:
- /Identity crypt passes through unchanged
- Custom crypt returns ENCRYPTION_UNSUPPORTED
- Missing /DecodeParms defaults to /Identity
- Works correctly with FlateDecode
- Comprehensive test coverage including proptests
- INV-8 maintained (no panics)
Also add missing malformed fixture entries to PROVENANCE.md.

Add pre-commit hook that runs check-provenance.sh before each commit
to ensure fixture files always have valid provenance entries. Update
PROVENANCE.md with validation section documenting the hook usage.
Acceptance criteria:
- PROVENANCE.md exists with one row per fixture file ✓
- Every fixture file enumerated; no orphans ✓
- License column populated; only approved licenses ✓
- SHA256 column populated; matches actual content ✓
- check-provenance.sh validates manifest; CI gate green ✓
- Synthetic fixtures point at generation scripts ✓

Fixed scripts/check-provenance.sh to properly validate PROVENANCE.md
against actual fixture files. The script was failing silently due to
subshell EXIT trap removing temp files before parent could read them,
and arithmetic expansion returning exit code 1 on zero value.
Changes:
- Replaced subshell pipes with process substitution
- Moved temp file cleanup to after reading
- Added validated variable initialization
- Added || true to prevent exit on zero arithmetic
All 200 classifier corpus fixtures have valid provenance entries
with matching SHA256 hashes. PROVENANCE.md already existed with
complete documentation.
