Add explicit enum constraints to page_type, severity, and confidence_source
fields in the generated JSON Schema for better validation.
Changes:
- Modified xtask/src/bin/gen_schema.rs to add explicit enum constraints
during schema generation via add_enum_constraints() function
- page_type enum: ["text", "scanned", "mixed", "broken_vector", "blank", "figure_only"]
- severity enum: ["info", "warning", "error", "fatal"]
- confidence_source enum: ["native", "heuristic", "ocr"]
- Regenerated docs/schema/v1.0/pdftract.schema.json with enum constraints
- Added .github/workflows/schema-gen.yml CI workflow for schema validation
The CI workflow validates:
1. Generated schema matches committed file (fails on diff)
2. JSON syntax is valid
3. Schema structure is correct ($id, $schema, title, $defs)
4. Enum constraints are present and have correct values
This ensures schema changes are reviewable in PRs and forces
developers to commit the updated schema when type definitions change.

criteria met:
- open() returns Ok/Err appropriately

- Rewrite FileSource to use Mutex<File> for Send + Sync support

Define the PdfSource trait abstraction over PDF byte sources. This trait
provides a uniform API for reading PDF data from different sources:
local files (MmapSource, FileSource), and eventually remote HTTPS PDFs.
Trait features:
- Read + Seek + Send + Sync supertrait bounds for rayon page-parallelism
- len() returns total source length
- read_range() returns Bytes for zero-copy slicing
- prefetch() with no-op default (MmapSource overrides for MADV_SEQUENTIAL)
MmapSource:
- Memory-mapped file access via memmap2
- Applies MADV_SEQUENTIAL advice via prefetch()
- Zero-copy read_range() using Bytes::copy_from_slice()
- Fallback for platforms/filesystems where mmap fails
FileSource:
- Standard I/O implementation using std::fs::File
- Read+Seek delegation to underlying File
- read_range() uses try_clone() for thread-safe concurrent access
Re-exports from pdftract-core::source::PdfSource.
Verification note: notes/pdftract-1mmq9.md documents completion status.
Parser module migration to use new PdfSource is deferred to follow-up.

Fixed test_aes_128_decrypt_roundtrip_with_valid_padding and two similar
tests to use the ciphertext slice returned by encrypt_padded_mut instead of
the entire buffer. The buffer is over-allocated to accommodate padding, but
only the returned slice contains valid ciphertext. Using the entire buffer
included trailing zeros that caused decryption to fail with invalid padding.

Blocker identified:
- Extraction pipeline (extract.rs) doesn't use Phase 4 layout pipeline
- Column detection functions never called in production
- SpanJson.column hardcoded to None (lines 1059, 1916)
- No end-to-end tests for acceptance criteria
Span struct HAS column field (line 179) but extraction doesn't use it.
Coordinator CANNOT CLOSE - sub-phase not end-to-end functional.
The encrypt_padded_mut API requires the buffer to be large enough to
hold the padded ciphertext. The tests were using plaintext.to_vec() which
only allocated plaintext.len() bytes, insufficient for padding.
Changed pattern:
- Before: plaintext.to_vec() (insufficient space)
- After: vec![0u8; plaintext.len() + 16] with copy_from_slice
Also fixed incorrect usage: encrypt_padded_mut returns Result<(), Error>,
not a length. Use data_copy.len() directly for ciphertext length.

Fixed compilation errors in Span constructors by adding missing `column: None` field.
Verified that the existing multi-output CLI parsing implementation meets all
acceptance criteria for bead pdftract-37qim.

- Add map_confidence_source to confidence module re-exports in lib.rs
- Remove duplicate map_confidence_source function from span/mod.rs

implemented in the confidence module from bead pdftract-2etcd. This change
completes the public API exposure and removes the duplicate implementation.
Acceptance criteria (all PASS):
- Single-glyph to_unicode span: confidence_source == Native
- Single-glyph shape_match span: confidence_source == Heuristic
- Mixed-glyph span (agl + shape_match): confidence_source == Heuristic
- 4.7 correction applied: Native -> Heuristic override
- OCR span: confidence_source == Ocr
- JSON serialization: lowercase strings

The map_confidence_source function was already implemented in
crates/pdftract-core/src/confidence.rs with comprehensive tests.
All acceptance criteria PASS:
- Unit tests for all 12 (UnicodeSource, corrected) combinations
- ToUnicode + corrected=true correctly downgrades to Heuristic

- Exhaustive match enforces compiler completeness
- INV-9 mapping table documented
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
Implement the map_confidence_source(unicode_source: UnicodeSource,
corrected_in_4_7: bool) -> ConfidenceSource function that collapses the
6 internal UnicodeSource variants down to the 3 schema-exposed
ConfidenceSource variants.
- Mapping follows INV-9 stable taxonomy
- Phase 4.7 correction override: corrected Unicode downgrades
Native -> Heuristic
- OCR is never affected by corrections (corrections apply to vector
text, not raster OCR output)
- Exhaustive match on UnicodeSource ensures compiler-enforced
completeness
Acceptance criteria:
- Unit tests for all (UnicodeSource, corrected) combinations PASS
- ToUnicode + corrected=true → Heuristic (override applies)
- Ocr + corrected=true → Ocr (override does NOT apply)
- INV-9 mapping table documented in code comments
Also fixed pre-existing compilation errors in encryption module:
- detection.rs: syntax error in PdfObject::Array construction
- mod.rs: removed duplicate EncryptionInfo struct definition

The invisible text filter in serialize_page_text() was always recomputing
block text from spans, but when block.spans is empty (no span data available),
this produced empty text for all blocks. Added fallback to use pre-computed
block.text when span data is missing, maintaining backward compatibility.
Also added special case for figure blocks to always emit empty text regardless
of span data.
All 111 text module tests pass, including all invisible text filtering tests
for Tr=0-7 and include_invisible=true/false combinations.
Acceptance criteria PASS:
- rendering_mode 3 excluded by default: ✓
- rendering_mode 3 included when flagged: ✓
- Mixed block emits visible: ✓
- All-invisible block produces empty (no spurious \n\n): ✓
- Tr=4 treated same as Tr=3: ✓

Add two example reverse-proxy configuration files to help operators
deploy pdftract serve with TLS and authentication in front of the
no-auth pdftract server.
- docs/operations/serve-nginx-example.conf: nginx config with Basic Auth,
proxy_pass to localhost:8080, /extract and /health endpoints
- docs/operations/serve-traefik-example.yaml: Traefik dynamic config with
BasicAuth middleware, buffering limits, separate health router
Both configs include top comments explaining the deployment model:
pdftract serve binds to 127.0.0.1:8080 with no auth; the reverse
proxy provides TLS termination and authentication.

The detect_headers_and_footers function was incrementing classified_count
every time a block was classified, even if it was already classified from
a previous sliding window iteration. With 10 pages and identical headers,
blocks on pages 1-9 would be reclassified multiple times (31 classifications
instead of 10).
Fixed by checking if block is already "header" or "footer" before incrementing
the counter.
All 25 header_footer tests now pass.

Implement confirm_columns function that partitions page into candidate
columns (regions between consecutive gaps + before-first + after-last),
counts unique lines whose first span's x0 falls within each candidate's
x-range, and promotes candidates with line_count >= 3 to confirmed columns.
Supporting code:
- ColumnGap struct with lo/hi bounds, width(), midpoint()
- detect_column_gaps function for zero-coverage region detection
- HasFirstSpan trait for first span bbox access
- CandidateColumn struct for tracking x_range and line_count
All 49 column tests pass, including all acceptance criteria.

Verified that merge_glyphs_to_spans() correctly implements:
- 5-trigger break detector (font_name, font_size delta >0.5pt, rendering_mode, RGB-normalized color, is_word_boundary)
- Word boundary handling option (a): append space to previous span
- Confidence tracking: minimum of all glyphs, source from worst glyph
- Bbox union of member glyphs
All 54 span module tests pass. Acceptance criteria:
- "Hello World" → 2 spans "Hello " and "World" ✓
- Font name change triggers break ✓
- Font size 12pt vs 12.2pt → 1 span (delta < 0.5pt) ✓
