6aabfa0c96 feat(pdftract-q15sh): implement v1 fingerprint algorithm
Implement Merkle SHA-256 fingerprint algorithm for PDF structural
fingerprinting as specified in Phase 1.7 of the plan.

Components:
- FingerprintInput struct with page data and catalog flags
- Per-page hashing: content streams (normalized), resources (sorted),
  geometry (4dp banker's rounding)
- Structure tree hash for tagged PDFs
- Catalog feature flag byte (encryption, JS, XFA, OCG)

Acceptance criteria:
- INV-3: 100% reproducible fingerprints (test passes)
- INV-13: Output format ^pdftract-v1:[0-9a-f]{64}$ (test passes)
- Performance: 100-page PDF in < 1ms (test passes)
- KU-7: WARN - no linearized fixtures available

Closes pdftract-q15sh

f76f3a647b test(pdftract-5tmcg): add cycle detection test for page tree flattener
Add test_cycle_detection_in_page_tree to verify that circular references
in the /Pages tree are detected and handled gracefully without panicking.
The test creates a page tree with a cycle (parent -> child1 -> child2 -> child1)
and verifies that the flattener returns the valid pages while pruning the
cyclic portion.

Acceptance criteria verified:
- 3-level /Pages inheritance with MediaBox: PASS
- EC-09 missing MediaBox defaults to US Letter: PASS
- /Pages tree with cycles detected: PASS
- /Rotate value 45 clamped to 0: PASS
- Page count validation: PASS
- proptest random shapes never panic: PASS
- INV-8 no panics on invalid input: PASS

eec40dad15 docs(pdftract-4iier): complete per-profile README documentation
Add comprehensive README files for all 9 built-in profiles (invoice,
receipt, contract, scientific_paper, slide_deck, form, bank_statement,
legal_filing, book_chapter). Each README includes:
- Match Criteria Summary: prose description of what makes a document match
- Extracted Fields table: field_name, type, description, example, source_hint
- Known Limitations: bullet list of edge cases and failure modes
- Sample Input Pointer: links to fixtures directory
- Configuration Tips: how to override via --profile or export

The xtask doc-profile skeleton generator was already implemented
and was used to generate the initial skeleton, which was then enhanced
with profile-specific human-authored content.

6477f7703f fix(pdftract-2bsfc): fix stream tests and catalog parser error handling
- Fix stream.rs test cases to use PdfStream::new() correctly (takes PdfDict directly, not wrapped in PdfObject::Dict)
- Fix catalog.rs test cases to use PdfObject::Dict(Box::new(dict)) (API change)
- Update parse_catalog to return Ok(empty_catalog) with STRUCT_MISSING_KEY diagnostic instead of Err when /Pages is missing (per bead acceptance criteria)

All catalog parser tests pass:
- 27 tests including 6 proptests for INV-8 compliance
- PageLabels number tree with mixed roman/arabic styles
- Tagged PDF detection via /MarkInfo
- Optional fields (Outlines, Version, etc.)
- proptest: random PdfObject as /Root never panics

b535638104 feat(pdftract-2bsfc): implement document catalog parser with PageLabels number tree
Implement the document catalog parser (/Root traversal) for PDF documents.
The catalog parser extracts all key entries from the document catalog
including Pages, Outlines, MarkInfo, StructTreeRoot, AcroForm, Names,
Metadata, PageLabels, OCProperties, OpenAction, AA, and Version.

Key structures:
- MarkInfo: parses /MarkInfo dictionary with is_tagged, user_properties, suspects
- PageLabelStyle: enum for all label styles (D, R, r, A, a)
- PageLabel: single page label with style, prefix, and start value
- PageLabelsTree: number tree parser for /PageLabels with /Nums and /Kids support
- OcProperties: stub for OCG implementation (delegated to dedicated bead)
- Catalog: main catalog struct with all required and optional fields

Number tree implementation:
- Parses /Nums arrays (leaf nodes with alternating key-value pairs)
- Supports /Kids arrays (internal nodes for recursive tree traversal)
- Provides get_label_with_start() and get_label() methods for lookup
- Correctly formats roman numerals (uppercase/lowercase) and letter sequences

All 27 tests pass including proptests for fuzzing robustness (INV-8).

3af009440e fix(pdftract-5z5d8): fix provenance validation script
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.

88278c362f feat(pdftract-4hn1): use Cow<'static, str> for diagnostic messages
Changed Diagnostic::msg from String to Cow<'static, str> to avoid
allocations for static error messages. Static messages now use
Cow::Borrowed, while dynamic formatted messages use Cow::Owned.

Also fixed peek_token lifetime issue - was returning reference to
local variable, now returns reference from cache.

Acceptance criteria:
- Token enum with all required variants
- Lexer struct with position tracking and diagnostics
- Diagnostic uses Cow<'static, str> for zero-allocation static messages
- All public methods implemented: new, next_token, peek_token, position, take_diagnostics
- All internal helpers implemented

5e66846288 docs(pdftract-147a): author SDK contract specification
Add comprehensive SDK contract specification at docs/notes/sdk-contract.md.
This document serves as the constitutional specification for all pdftract
SDK implementations across all languages.

The contract defines:
- Method surface (9 methods mirroring CLI/MCP tools)
- Error mapping (CLI exit codes → native exceptions)
- Versioning compatibility rules (MAJOR lock, MINOR flexibility)
- Option-naming conventions (CLI flag → language-native case)
- Native type-mapping requirements (Document, Page, Span, Block, Match, Fingerprint, Classification)
- Async conventions per language
- Conformance enforcement (100% pass required)
- Change policy (ADR required for contract changes)

MEDIUM:
- Add JBIG2 OCR limitation: requires full-render; OCR_JBIG2_UNSUPPORTED diagnostic
- Add Standard-14 font skip for Level 3 fingerprinting (no embedded program)
- Change flags field from EnumSet<SpanFlag> to u8 bitmask (removes undocumented enumset dep)

bcccc98fd7 docs(plan): fix 30 gaps from Round 1 gap review
CRITICAL fixes:
- Remove jpeg-decoder from Phase 1.5 crates (contradicted dep matrix)
- Specify word boundary adaptive threshold: text space, per-font-switch window, 20-glyph seed
- Add page_number (1-based) alongside page_index (0-based) to resolve SDK/schema mismatch
- Add mcid: Option<u32> to Glyph struct (was defined in 3.4 but missing from 3.2)
- Add aes + rc4 crates under new decrypt feature; document crypto dependency

HIGH fixes:
- Specify font fingerprint database format (phf::Map, SHA-256, ~500KB, JSON source)
- Fix Level 4 shape DB cross-ref (was "Phase 2.3", corrected to research doc); add Phase 2.5 definition
- Document header/footer cross-page pass as sequential post-rayon with Levenshtein matching
- Replace Tesseract box-file hint approach with PSM_SPARSE_TEXT + post-OCR validation
- Add HTTP serve security constraints: decompression bomb limit, auth guidance, no path params
- Add JavaScript detection spec to Phase 1.4 (all four JS action locations)
- Align CI benchmark gate to 10x pdfminer.six (was 5x, contradicted primary objectives)
- Add cargo bloat CI gate for phf word list size; bloomfilter fallback if >250KB
- Add pdftract-py-ci WorkflowTemplate note with manylinux/osxcross/cross approach
- Add ConfidenceSource enum → schema string mapping table in Phase 4.1

MEDIUM fixes:
- Define docs/schema/v1.0/pdftract.schema.json as Phase 6.1 deliverable
- Add unicode-bidi crate to dep matrix and Phase 4.2 for RTL detection
- Define Color enum with CSS hex conversion rules in Phase 3.1
- Remove bytes crate from Phase 1.2 (belongs in serve feature only; use Arc<[u8]>)
- Specify NDJSON buffer Condvar blocking behavior at window saturation
- Clarify pdftract:ocr vs pdftract:full Docker image tags and size budgets
- Add Docstrum parameters: k=5, Euclidean, ±30° constraints, root node definition
- Add code and formula block kind detection heuristics to Phase 4.4
- Add OCG visibility handling to Phase 1.4 (ON/OFF from /OCProperties /D /AS)
- Add linearized PDF detection and dual-xref merge to Phase 1.3
- Add HTTP 413 to error table with custom JSON rejection handler
- Add Phase 0: CI Infrastructure section (pdftract-ci WorkflowTemplate)

LOW fixes:
- Clarify Name length limit: 127 bytes pre-expansion, matching PDF spec 7.3.5
- Reorder preprocessing pipeline: contrast normalization before binarization (was after)
- Add CIDToGIDMap stream form: 2-byte big-endian GID array

d161d109b3 docs(plan): revise plan to center accuracy/speed/weight as hard targets
- Add Primary Objectives section with CI-gated measurable targets:
  accuracy (CER <0.5%, WER <3%, readability >0.85), speed (100pp <3s,
  10x vs pdfminer), weight (<4MB default binary, <20 default deps)
- Add feature-flag strategy: axum/tokio/pdfium/pyo3 are all optional;
  default build is core extraction + CLI only
- Add Phase 4.7: text readability validation and correction pipeline
  (ligature repair, hyphenation, mojibake detection, readability scoring)
- Make pdfium-render explicitly optional (full-render feature) vs. the
  always-present direct image compositing path
- Add Tier 4 competitive benchmark suite (vs. pdfminer.six, pypdf, pdfplumber)
- Remove jpeg-decoder and whichlang from dependency matrix (unnecessary)
- Rename implementation-plan.md → plan.md (matches CLAUDE.md reference)
