225f96c241 fix(pyo3): correct extract_text_fn call in extract_markdown stub
The extract_markdown stub was calling extract_text instead of
extract_text_fn, causing a compilation error. This fixes the
function name to match the exported function from extract_text.rs.

This completes the extract_text PyO3 entry point implementation,
which was already present in extract_text.rs and lib.rs.

f85e5149dd feat(pdftract-91e1i): HTTP fetch sequence implementation
Implement orchestration layer connecting HttpRangeSource to Phase 1.3
xref resolver and Phase 1.4 document model for remote PDF access:

- Document::open_remote() public API for remote PDF loading
- Progressive tail fetch (16 KB → 1 MB) for startxref location
- Xref forward-scan disabled for remote sources (via is_remote check)
- Page-by-page on-demand fetch via HttpRangeSource caching
- Resource lazy load through XrefResolver cache
- HEAD probe with 405 fallback, no Content-Length handling

Acceptance criteria:
 open_remote(url) returns Document with correct page count
 HEAD failure modes (405, no Content-Length, 401) handled
 xref forward-scan disabled for remote (is_remote check)
 Page-by-page on-demand fetch (HttpRangeSource LRU cache)
 INV-8 maintained (all errors return Result)

Files modified:
- crates/pdftract-core/src/document.rs (Document::open_remote, from_source)
- crates/pdftract-core/src/remote.rs (progressive tail fetch)
- crates/pdftract-core/src/lib.rs (re-exports)

dd2d3502c6 feat(glyph-shape): implement font corpus fetch script and shape DB generation
Implemented scripts/fetch-shape-corpus.sh for downloading open-licensed
font corpus and generating glyph shape database for L4 recognition.

- Script downloads fonts from build/shape-corpus-manifest.txt
- Copies LICENSE files to build/font-licenses/ for compliance
- Idempotent: skips already-present fonts
- Fixed xtask center_bitmap_32x32 overflow bug (width/height > 32)

Generated build/glyph-shapes.json with 9,141 glyphs (> 4500 target):
  - DejaVu Sans: 4,459 glyphs (Latin Extended, Greek, Cyrillic)
  - Roboto: 2,392 glyphs (Latin Basic, extended)
  - JetBrains Mono: 1,176 glyphs (monospace)
  - Source Code Pro: 1,124 glyphs (monospace)

build/font-licenses/COMPLIANCE.md documents OFL derivative-work analysis
for pHash data redistribution.

Closes: pdftract-1i8n

61babb0991 test(bf-5dnh1): add memory ceiling enforcement for proptests
Add scripts/run-proptest-with-limits.sh to run property tests under
cgroup MemoryMax, ensuring pathological cases fail fast with allocation
errors instead of OOMing the host.

Coordinated with bf-1g1fd (CI memory-ceiling gate) to provide local
development parity with CI enforcement.

Changes:
- Add scripts/run-proptest-with-limits.sh (cgroup v2/v1 wrapper)
- Add scripts/README.md documenting memory ceiling enforcement

Memory limits:
- Proptests: 2048 MB cgroup MemoryMax (local)
- Fuzz tests: 1536 MB cgroup + 1024 MB libfuzzer RSS (existing)

Proptest input size caps (already in place):
- Lexer/object parser: up to 10 KB inputs
- Xref/stream parsers: up to 100 KB inputs
- Nested structures: depth-limited

c621947686 feat(bf-1g1fd): implement CI memory-ceiling gate with cgroup MemoryMax enforcement
Implements Tier-1 memory ceiling gate that enforces RSS budgets for PDF
extraction, analogous to cargo-bloat for binary size.

Changes:
- CI: Add memory-ceiling template with cgroup MemoryMax (1.5 GB)
- CI: Add cgroup MemoryMax enforcement to test-glibc (6 GB) and test-musl (4 GB)
- CI: Add cgroup MemoryMax + libfuzzer rss/malloc limits to fuzz workflow
- xtask: Implement memory-ceiling command with peak RSS sampling
- Add perf fixtures (100-page, 10k-page) for memory testing
- Add run-fuzz-with-limits.sh for local fuzz testing with memory caps
- Register perf fixtures in PROVENANCE.md

Memory budgets enforced:
- Buffered 100-page PDF: < 512 MB
- Streaming mode: < 256 MB (constant in page count)
- Adversarial fixtures: < 1 GB hard ceiling

Closes bf-1g1fd

660a9401ef feat(pdftract-59zz): implement MCP bearer token ingress channels and TH-03 enforcement
Implements secure MCP bearer-token ingress channels and TH-03 startup abort
enforcement per plan lines 874, 915-921, 922-924.

## Changes
- Add `--auth-token-file PATH` flag (RECOMMENDED channel)
- Add `PDFTRACT_MCP_TOKEN` env var support
- Reject `--auth-token VALUE` unless `PDFTRACT_INSECURE_CLI_TOKEN=1`
- Enforce TH-03: require token for non-loopback bind addresses (exit 78)
- Loopback exemption for 127.0.0.0/8 and ::1/128

## Files
- crates/pdftract-cli/src/mcp/auth.rs: Token resolution with priority order
- crates/pdftract-cli/src/mcp/bind.rs: TH-03 bind security check
- crates/pdftract-cli/src/mcp/server.rs: MCP server entry point
- crates/pdftract-cli/src/mcp/mod.rs: Module exports
- crates/pdftract-cli/src/main.rs: CLI arguments
- crates/pdftract-cli/Cargo.toml: Add secrecy, tempfile dependencies

## Acceptance Criteria
-  --auth-token-file PATH flag implemented
-  PDFTRACT_MCP_TOKEN env var resolved
-  --auth-token VALUE rejected (exit 64) unless PDFTRACT_INSECURE_CLI_TOKEN=1
-  mcp --bind ADDR with non-loopback ADDR and no token: aborts with exit 78
-  mcp --bind ADDR with loopback ADDR and no token: succeeds
-  mcp --bind ADDR with token: succeeds regardless of address
- ⏸️ Inspector token: Phase 7.9 (not yet implemented)
- ⏸️ TH-03 test: separate bead

7fed5a0a6f docs(pdftract-5l9m): add CI validation script and verification note
Add CI validation script for checking unauthorized expose_secret() call
sites. The script validates that all uses of expose_secret() are in
approved locations (SecretFingerprint and test code).

Also add verification note summarizing the bead completion status.

Per pdftract-5l9m acceptance criteria:
- CI grep guard rejects unauthorized expose_secret() call sites
- Verification documents existing SecretString wrapping status

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.

633eba61b1 test(classifier): add 200-document labeled corpus for Phase 5.6
- Create tests/fixtures/classifier/ with 200 synthetic PDFs:
  - 50 invoices with bill-to/ship-to, item tables, totals
  - 50 scientific papers with abstracts, sections, references
  - 50 contracts with clauses, legal terminology, signatures
  - 50 misc documents (8 receipts, 8 forms, 7 bank statements,
    7 slide decks, 7 legal filings, 6 book excerpts, 7 magazines)

- Add MANIFEST.tsv mapping each document to its expected type
  with source URL and license (all MIT-0 synthetic data)

- Add scripts/generate_test_corpus.py to regenerate the corpus
  using reportlab for PDF generation

- Add tests/test_classifier_corpus.rs with validation harness:
  - test_corpus_manifest_validity: verifies manifest structure
    and file existence (PASSES)
  - test_classifier_corpus_accuracy: will validate precision/
    recall/F1 when classifier is implemented (SKIP for now)
  - test_classifier_reproducibility: will verify deterministic
    classification (SKIP for now)

- Add tests/fixtures/classifier/README.md documenting corpus
  structure, generation process, and acceptance criteria

Total corpus size: ~0.4 MB (each PDF < 5 KB)

Acceptance criteria (from plan.md Phase 5.6):
- Per-class precision and recall >= 0.85
- Macro-F1 >= 0.88
- Reproducibility: identical output for same document
