2fe45079b3 fix(pdftract-1w5u1): ensure doctor output fits within 80 columns for all modes
The detail field truncation in human.rs only applied to TTY output,
causing lines to exceed 80 columns when piping to cat or using --no-color.

Fix: Apply truncation uniformly across all output modes:
- TTY mode: Use actual terminal width from terminal_size crate
- Non-TTY/--no-color: Assume 80 columns and truncate accordingly
- Detail field max width: term_width - 38 columns

Max line width now exactly 80 characters for all output modes.

Acceptance criteria verified:
- TTY colored table with summary ✓
- Non-TTY plain text, no ANSI ✓
- --json single JSON object ✓
- --json summary counts ✓
- --features list, exit 0 ✓
- --no-color plain text in TTY ✓
- 80-column terminal width ✓
- N/A excluded from human, in JSON ✓

e2c1e2817b feat(pdftract-2i6rt): implement cache CLI subcommand and HTTP integration
This commit implements Phase 6.9.6: surfacing the cache as user-visible
CLI and HTTP affordances.

## Changes

- Add `pdftract cache` subcommand with stats/clear/purge actions
  - `stats DIR`: show entry count, size, hit ratio, age distribution
  - `stats DIR --json`: emit JSON with same fields
  - `clear DIR`: delete all entries (preserves index.json/sentinel)
  - `purge DIR --older-than 30d`: delete entries older than duration
  - `purge DIR --version '<1.0.0'`: version constraint purge (stub)

- Add global flags to extract-style subcommands
  - `--cache-dir DIR`: enable cache at directory
  - `--cache-size SIZE`: set LRU size limit (default 1 GiB)
  - `--no-cache`: disable cache for this call

- Add `X-Pdftract-Cache: hit|miss|skipped` HTTP header on /extract endpoints
  - Set in response headers before body streaming

- Add JSON metadata fields
  - `metadata.cache_status`: "hit" | "miss" | "skipped"
  - `metadata.cache_age_seconds`: integer seconds (present only on hit)

## Acceptance Criteria

-  pdftract cache stats on empty dir: "Entries: 0"
-  pdftract cache stats on populated dir: correct counts and ratios
-  pdftract cache clear -y: deletes entries, preserves index/sentinel
-  pdftract cache purge --older-than: deletes old entries
-  extract --cache-dir: metadata.cache_status populated
-  extract second run: cache_status "hit" with age
-  extract --no-cache: cache_status "skipped"
-  HTTP serve: X-Pdftract-Cache header present
-  --cache-size parsing: 4GiB → 4 * 1024^3 bytes

## Modules

- crates/pdftract-cli/src/cache_cmd.rs: subcommand implementation
- crates/pdftract-cli/src/serve.rs: HTTP handler integration
- crates/pdftract-cli/src/main.rs: CLI flag definitions
- crates/pdftract-core/src/cache/mod.rs: extract_with_cache() integration
- crates/pdftract-core/src/extract.rs: cache_status metadata fields

3d9e93fef4 feat(pdftract-39g4j): implement --receipts CLI flag + ExtractionOptions threading
Implement the --receipts CLI flag accepting "off" | "lite" | "svg" with default "off".
Thread the ExtractionOptions.receipts field through the extraction pipeline so that
receipts are generated for spans and blocks based on the selected mode.

Changes:
- CLI: Added --receipts flag with clap value_parser for runtime validation
- CLI: Added feature check for SVG mode (requires 'receipts' feature)
- MCP tools: Added receipts field to ExtractArgs, ExtractTextArgs, ExtractMarkdownArgs
- MCP tools: Added build_extraction_options() to parse receipts mode
- Core: Added extract.rs module with extract_pdf(), extract_page(), generate_receipt()
- Core: Added ExtractionOptions with ReceiptsMode enum (Off/Lite/SvgClip)
- Core: Added receipts feature flag to Cargo.toml

7ea539f8aa feat(pdftract-39g4j): implement --receipts CLI flag + ExtractionOptions.receipts threading
- Add value_parser = ["off", "lite", "svg"] to --receipts CLI flag for clap validation
- Add receipts field to ExtractTextArgs and ExtractMarkdownArgs in MCP tools args
- Add ExtractionOptions and ReceiptsMode to pdftract-core (options.rs module)
- Expose options module in pdftract-core/lib.rs

The CLI now validates receipts mode at parse time with helpful error messages.
MCP tools accept receipts argument matching the schema defined in sibling 6.7.5.
ExtractionOptions struct provides the threading mechanism for the extraction pipeline.

Acceptance criteria:
- PASS: CLI validates --receipts values (off/lite/svg only)
- PASS: CLI shows proper help text with possible values
- PASS: ExtractionOptions serializes for HTTP/MCP transport
- PASS: MCP tools args have receipts field
- WARN: Full extraction implementation pending (deferred to extraction beads)

Closes pdftract-39g4j

7566ab0f0f feat(pdftract-36wlt): implement verify-receipt subcommand + verifier protocol
Implement the pdftract verify-receipt subcommand and the underlying verifier
protocol. The verifier validates receipts against original PDFs by checking:
(1) PDF fingerprint matches, (2) at least one span has bbox overlap >= 90% IoU,
(3) that span's NFC-normalized SHA-256 equals the receipt's content_hash.

Modules:
- crates/pdftract-core/src/receipts/verifier.rs: verifier protocol logic
- crates/pdftract-cli/src/verify_receipt.rs: CLI integration
- crates/pdftract-core/src/document.rs: PDF parsing helpers

Exit codes:
- 0: success
- 10: fingerprint mismatch
- 11: bbox mismatch (no span meets 90% IoU threshold)
- 12: content hash mismatch
- 1: extraction failed

7833d8c514 feat(pdftract-1rami): implement MCP tool catalog with 10 tools
Implement the MCP tool catalog for pdftract with all 10 tools wired to
the extraction surface via the MCP protocol. The tool registry provides
typed argument schemas (JSON Schema via schemars), structured error
mapping (Rust errors → JSON-RPC error codes), and per-invocation
observability logging.

- Tool registry with Tool trait and 10 tool implementations
- JSON Schema input schemas for all tools (draft-07 compliant)
- Error code mapping: -32000 NOT_YET_IMPLEMENTED, -32001 PDF_ENCRYPTED,
  -32002 IO_ERROR, -32003 PATH_INVALID
- Observability logging: structured stderr log line per tools/call
- Integration tests: 10/11 pass (1 ignored for encrypted fixture)
- Registry unit tests: 23/23 pass

Tools implemented:
- extract, extract_text, extract_markdown (stubs pending Phase 6)
- search (stub pending Phase 6)
- get_metadata, hash (fully implemented, fast paths)
- get_table, get_form_fields, get_attachments, classify (stubs return
  NOT_YET_IMPLEMENTED per spec)

Acceptance criteria: 8/8 PASS (2 WARN for Phase 6 stubs)

7eed5ca55a feat(pdftract-24kut): enforce MCP transport mutual exclusion at CLI parse
Per ADR-006: stdio and HTTP transports are mutually exclusive because they
have opposite stdout discipline (stdio: JSON-RPC sink; HTTP: log channel).

Changes:
- Add clap ArgGroup with multiple(false) to enforce --stdio XOR --bind
- Default to stdio mode when neither flag is specified
- Change --bind from required String to Option<String>
- Add ADR-006 reference to help text and doc comments
- Add unit tests for CLI argument validation

Acceptance criteria:
- pdftract mcp → launches in stdio mode (default)
- pdftract mcp --stdio → launches in stdio mode
- pdftract mcp --bind ADDR → launches in HTTP+SSE mode
- pdftract mcp --stdio --bind ADDR → exits 2 with clap conflict error
- pdftract mcp --help shows mutual exclusivity note
- Unit test verifies ArgGroup conflict on dual-transport invocation

c4ff5194dd feat(pdftract-67tm8): implement MCP stdio transport with integration tests
Implements the stdio transport for the MCP server, enabling communication
with local agents (Claude Desktop, Claude Code, Continue, Cursor) over
standard input/output with Content-Length framing.

Core features:
- LSP-style Content-Length framing with \r\n terminators
- JSON-RPC 2.0 message parsing and serialization
- INV-9 compliance: stdout contains only JSON-RPC frames
- Panic hook redirects panics to stderr
- SIGTERM handler for graceful shutdown
- Parse errors return -32700 with id: null, then continue

Acceptance criteria:
-  Piping tools/list with framing produces expected response < 50ms
-  EOF on stdin → clean exit within 100ms
-  Malformed JSON → -32700 error, subsequent requests work
-  No println!/log output to stdout (INV-9 enforced)
-  Panics go to stderr, no partial JSON on stdout
-  SIGTERM → exit 0, SIGINT → immediate non-zero exit

Tests added:
- crates/pdftract-cli/tests/mcp-stdio.rs (8 integration tests, all pass)
- All 49 existing unit tests continue to pass

e176fa68ad fix(pdftract-2hm4): fix hex string lexer invalid char handling and whitespace/comment skipping
Two fixes:

1. Hex string lexer now flushes dangling nibble when encountering invalid
   characters. For `<4X8Y>`, the X and Y are invalid, so we flush nibble 4
   as 0x40, then flush nibble 8 as 0x80, producing `\x40\x80`.

2. Fixed skip_whitespace_and_comments() to properly handle whitespace
   after comments. The previous logic only continued looping if the next
   byte was `%`, missing cases where whitespace follows a comment.

All 52 lexer tests pass.
