feat(bf-okdnk): add CMAP output parsing and inspection

Browse source 
- Add iter() method to ToUnicodeMap for accessing CMAP structure
- Extend test_cmap_unmapped_glyph_skip to show CMAP contents
- Extend test_cmap_multiple_mappings_with_unmapped_check to show mappings
- Add debug output for inspection of source bytes and target chars
- Add verification note at notes/bf-okdnk.md

This enables inspection of CMAP output structure to verify unmapped glyphs
are properly handled before implementing actual filtering logic.

Closes bf-okdnk

//! CLI invocation fixture discovery and enumeration
//!
//! This test module provides comprehensive fixture discovery for CLI testing:
//! - Discovers all PDF fixtures from the main test fixtures directory
//! - Provides test-accessible fixture enumeration
//! - Supports category-based filtering (encrypted, forms, ocr, malformed, etc.)
//! - Enables bulk CLI invocation testing
//!
//! The fixtures are organized in /tests/fixtures/ by category:
//! - encrypted/: Password-protected and encrypted PDFs
//! - forms/: PDFs with AcroForm and XFA forms
//! - ocr/: Scanned documents requiring OCR processing
//! - malformed/: Corrupted or malformed PDFs for error handling
//! - scanned/: Scanned documents and receipts
//! - cjk/: Chinese/Japanese/Korean language documents
//! - fonts/: PDFs with various font encodings and subsets
//! - And more...

# Diagnostic Output Files in pdftract Build Directories
# Diagnostic Output Files Discovery (bf-3e0vl)
## Summary
Successfully located and documented diagnostic output files in the project build directories.
Located and documented diagnostic output files stored in the project build and test output directories.
## Primary Diagnostic Output Location
## Build Diagnostic Files (target/ directory)
### Test Output Diagnostics
**Path Pattern:** `target/debug/.fingerprint/<crate-hash>/output-test-*`
### Location: `/home/coding/pdftract/target/debug/build/*/stderr`
These files contain JSON-formatted compiler and test diagnostics, including:
- Compiler warnings (unused imports, dead code, unreachable code, unused variables)
- Error messages with line/column information
- Suggested fixes and machine-applicable suggestions
Build stderr files are stored in build-specific subdirectories within `target/debug/build/`. These contain compiler warnings and build diagnostic information.
#### Most Recent Example
**File:** `/home/coding/pdftract/target/debug/.fingerprint/pdftract-cli-8b8c0ec31cd61f5b/output-test-lib-pdftract_cli`
**Example file:** `/home/coding/pdftract/target/debug/build/pdftract-core-0d428a00850f9797/stderr`
**Details:**
- **Size:** 89,369 bytes (~87 KB)
- **Created:** 2026-07-06 17:32:20
- **Lines:** 50 lines (one JSON diagnostic per line)
- **Last accessed:** 2026-07-06 17:34:29
- **File size:** 760 bytes
- **Last modified:** July 6, 2026 17:23
- **Contents:** Cargo compiler warnings about missing optional checksum files and unused code
**Sample content:**
```
cargo:warning=Checksum file not found (optional): std14-metrics.json
cargo:warning=Checksum file not found (optional): ../../../build/glyph-shapes.json
cargo:warning=Checksum file not found (optional): named-encodings.json
cargo:warning=Checksum file not found (optional): predefined-cmaps/adobe-japan1.json
**Content Sample:**
```json
{"$message_type":"diagnostic","message":"unused import: `PathBuf`","code":{"code":"unused_imports","explanation":null},"level":"warning","spans":[...]}
```
**Pattern:** Each build crate has its own subdirectory with a `stderr` file (e.g., `pdftract-core-HASH/stderr`, `pdftract-cli-HASH/stderr`).
### Other Recent Diagnostic Files
- `target/debug/.fingerprint/pdftract-core-e8f303349505d378/output-test-integration-test-verify_proptest_catches_bugs` (2.7 KB, 2026-07-06 17:23)
- `target/debug/.fingerprint/pdftract-py-77353842664f24e0/output-test-lib-pdftract` (timestamp: 1783373534)
- `target/debug/.fingerprint/pdftract-libpdftract-2ba5f4872f785275/output-test-lib-pdftract` (timestamp: 1783373534)
### File Count
## Expected Diagnostic Fixtures
- **Total stderr files found:** ~150+ (one per build crate dependency)
- **Non-empty stderr files:** ~10-15 (containing actual compiler warnings)
- **Most recent:** July 6, 2026 17:30
**Location:** `tests/error_recovery/fixtures/*.expected_diagnostics.json`
## Test Output Files (notes/ directory)
These are test fixtures that define expected diagnostic outputs for error recovery tests.
### Location: `/home/coding/pdftract/notes/`
**Examples:**
- `missing_endobj.expected_diagnostics.json` - Tests missing `endobj` marker detection
- `missing_mediabox_all_pages.expected_diagnostics.json` - Tests missing MediaBox recovery
- `combined_failures.expected_diagnostics.json` - Tests multiple error conditions
- `truncated_mid_stream.expected_diagnostics.json` - Tests truncated stream recovery
- `xref_30pct_bad_offsets.expected_diagnostics.json` - Tests corrupted xref recovery
- `int_overflow_bbox.expected_diagnostics.json` - Tests integer overflow in bounding boxes
- `nested_failure.expected_diagnostics.json` - Tests nested error conditions
The `notes/` directory contains diagnostic output files from test runs and CLI invocations. These are more comprehensive and user-readable than the build stderr files.
**Sample Structure:**
```json
{
"description": "Object 5 is missing its endobj marker",
"expected_diagnostics": [
{
"code": "STRUCT_INVALID_XREF_ENTRY",
"min_count": 1,
"description": "Parser should detect object 5 is malformed and recover"
}
],
"expected_objects": "at least 6 objects parsed (objects 6+ should still be accessible)"
}
```
**Most recent diagnostic file:** `/home/coding/pdftract/notes/bf-677eo-output.txt`
## Nextest Configuration
- **File size:** 104K (104,000+ bytes)
- **Last modified:** July 6, 2026 16:36
- **Contents:** Full compiler output with warnings, dead code analysis, and cfg condition checks
Per `.config/nextest.toml`, nextest stores test data in:
- **Config:** `dir = "target"` (default: `target/nextest`)
- Actual diagnostic outputs are stored in `.fingerprint` subdirectories as shown above
**Other diagnostic files found:**
- `bf-5ucbr-pdftract-debug-output.json` - JSON debug output from pdftract CLI
- `bf-694ie-extract.log` - Extraction operation log
- `bf-694ie-help.log` - CLI help output log
- `bf-3j4ec-*.txt` - Multiple output format test files (text, ndjson, json)
## Acceptance Criteria Status
✅ **PASS** - At least one diagnostic output file found (50+ files located)
✅ **PASS** - Full paths documented (primary path and fixtures documented)
✅ **PASS** - File creation/modification times noted (2026-07-06 17:32:20 for most recent)
✅ **PASS** - File sizes reasonable (ranging from 2KB to 87KB, not empty or excessively large)
## Files Modified
- `notes/bf-3e0vl.md` (this file) - Updated with actual diagnostic output findings
## Key Findings
1. **Build stderr files** are small (usually 0 bytes, 760 bytes when non-empty) and contain compiler warnings
2. **Test output files** in `notes/` are much larger (up to 104K) and contain comprehensive diagnostic information
3. **File naming pattern:** Build stderr uses crate-HASH directory, test outputs use bead-ID prefix
4. **Most recent diagnostic:** `bf-677eo-output.txt` (104K, July 6, 2026 16:36)
## Access Patterns
### For build diagnostics:
```bash
# Find most recent non-empty stderr files
find /home/coding/pdftract/target/debug/build -name "stderr" -size +0c -exec ls -lth {} \; | head -10
```
### For test outputs:
```bash
# Find most recent diagnostic files
ls -lht /home/coding/pdftract/notes/*.log /home/coding/pdftract/notes/*output* 2>/dev/null | head -10
```
## Recommendations
1. The `notes/` directory appears to be the primary location for comprehensive test diagnostic outputs
2. Build stderr files are useful for tracking compiler warnings across build iterations
3. Test output files in `notes/` are substantially larger and more detailed than build diagnostics
1. **Diagnostic files are compiler/test output** stored in `.fingerprint` directories
2. **Format is JSON-lines** (one JSON diagnostic object per line)
3. **Content includes compiler warnings** about unused code, dead code, unreachable code, etc.
4. **Test fixtures define expected diagnostics** for error recovery testing scenarios
5. **Files are actively updated** during test runs and builds

# Mirror and Remote Configuration Audit
**Audit Date:** 2026-07-06
**Task ID:** bf-4eprp
**Repository:** jedarden/pdftract
## Executive Summary
The audit reveals a **critical configuration issue**: the local git tracking branch is configured to follow `github/main` instead of `origin/main`, violating the workspace convention that `origin` should point to Forgejo (the primary repository). Additionally, the Forgejo-to-GitHub mirror is failing due to large test files exceeding GitHub's size limits.
## Findings
### 1. Forgejo Push Mirror Status
**Mirror Entry:** ✅ EXISTS
- **Remote Address:** `https://github.com/jedarden/pdftract.git`
- **Created:** 2026-05-16T19:51:17Z
- **Last Update Attempt:** 2026-07-06T21:13:08Z
- **Sync on Commit:** true
- **Interval:** 10m0s
**Mirror Status:** ❌ **BLOCKED - Push Rejected**
The mirror is failing consistently with the following error:
```
PushRejected Error: remote: error: File --1.ppm is 235.13 MB; this exceeds GitHub's file size limit of 100.00 MB
remote: warning: File test_parse_simple is 60.74 MB; this is larger than GitHub's recommended maximum file size of 50.00 MB
GH001: Large files detected. You may want to try Git Large File Storage
```
**Root Cause:** Large test fixture files in the repository exceed GitHub's 100MB file size limit.
### 2. Local Git Remote Configuration
**Remote Configuration:**
```
github -> https://github.com/jedarden/pdftract.git (fetch/push)
origin -> https://git.ardenone.com/jedarden/pdftract.git (fetch/push)
```
**Branch Tracking Configuration:**
```
branch.main.remote=github ← ❌ INCORRECT (should be 'origin')
branch.main.merge=refs/heads/main
```
**Issue:** The `main` branch is configured to track `github/main` instead of `origin/main`. This violates the workspace convention that `origin` should point to Forgejo (the canonical source).
### 3. Commit Gap Analysis
**Current State:**
- `origin/main` (Forgejo): beef8453 (current)
- `main` (local): beef8453 (current)
- `github/main` (GitHub): 88b4f0da (308 commits behind)
**Commit Gap:** 308 commits difference between Forgejo and GitHub
- **Forgejo is ahead of GitHub** by 308 commits
- This is the reverse of what was initially stated (84 commits behind)
- The gap has grown since the mirror started failing on large files
**Recent commits that GitHub is missing (showing first 5 of 308):**
1. beef8453 - docs(bf-1j21w): verify assert_stderr_contains method
2. c29fb0cb - docs(bf-224fc): update verification note for forms_integration
3. b91e2b0c - docs(bf-1j21w): document assert_stderr_contents non-existence
4. 951dd56c - docs(bf-snis1): add verification note for forms_integration module
5. 862fe9b3 - feat(bf-4b7pm): implement temporary storage for benchmark metrics
### 4. Large Files Causing Mirror Failure
**Problematic Files:**
- `--1.ppm`: 235.13 MB (exceeds GitHub's 100MB hard limit)
- `test_parse_simple`: 60.74 MB (exceeds GitHub's 50MB recommended limit)
**Location:** These files appear to be test fixtures, likely in `tests/fixtures/` or `tests/fixtures/malformed/` directories.
## Issues Summary
| Issue | Severity | Status |
|-------|----------|--------|
| Branch tracking wrong remote | HIGH | NOT FIXED |
| Mirror blocked by large files | HIGH | BLOCKING SYNC |
| 308 commits not mirrored to GitHub | MEDIUM | BLOCKING |
## Recommendations
### Immediate Actions Required:
1. **Fix Branch Tracking Configuration:**
```bash
git config --local branch.main.remote origin
git config --local branch.main.merge refs/heads/main
```
This will make `main` track `origin/main` (Forgejo) instead of `github/main`.
2. **Resolve Large File Issue:**
- Investigate if `--1.ppm` and `test_parse_simple` can be removed or moved to LFS
- Consider using Git LFS for large test fixtures
- Alternatively, exclude these files from the repository and generate them programmatically
3. **Verify Mirror Recovery:**
- After large file issue is resolved, manually trigger a mirror sync
- Verify that the 308 pending commits successfully push to GitHub
### Follow-up Actions:
1. **Establish File Size Policy:** Create CI checks to prevent files >50MB from being committed
2. **Git LFS Migration:** Consider migrating large test fixtures to Git LFS
3. **Documentation:** Update workspace documentation to specify branch tracking requirements
## Technical Details
### Forgejo Mirror Configuration
- **API Endpoint:** https://git.ardenone.com/api/v1/repos/jedarden/pdftract/push_mirrors
- **Mirror Type:** push (Forgejo → GitHub)
- **Sync Frequency:** Every 10 minutes + on commit
- **Authentication:** Token-based (Forgejo API token)
### Git Configuration Files
- **Local Config:** `/home/coding/pdftract/.git/config`
- **Branch Settings:** `branch.main.remote=github` (needs correction)
- **Remote Settings:** Properly configured (origin=Forgejo, github=GitHub)
### Commit History Analysis
- **Last successful mirror push:** Unknown (mirror has been failing)
- **First problematic commit:** Around the time large files were added
- **Oldest missing commit on GitHub:** 1c6f26ec (fix: clean up unused imports in hash.rs)
## Next Steps for Parent Bead (bf-320gz)
The following child beads should address:
1. Fix branch tracking configuration
2. Resolve large file blocking mirror sync
3. Verify and test mirror recovery
4. Update documentation and CI policies
This audit provides all necessary context for implementing these fixes.

# Verification Note: bf-6bsry - Select and verify test fixture
## Task
Choose a small, fast PDF fixture from tests/fixtures/encoding/ and verify it exists and is readable.
## Acceptance Criteria - ALL PASS
### ✅ PASS: Verify tests/fixtures/encoding/ directory exists
- Directory exists at `/home/coding/pdftract/tests/fixtures/encoding/`
- Contains 14 files (7 PDF files, 7 supporting files)
### ✅ PASS: List available PDF files in the directory
Available PDF fixtures (all < 50KB):
1. `agl-only.pdf` - 597 bytes
2. `fingerprint-match.pdf` - 1,059 bytes (SELECTED)
3. `no-mapping.pdf` - 660 bytes
4. `shape-match.pdf` - 926 bytes
5. `test_working_copy.pdf` - 374 bytes
6. `unmapped-glyphs.pdf` - 723 bytes
### ✅ PASS: Select fingerprint-match.pdf (recommended)
- **Selected fixture**: `tests/fixtures/encoding/fingerprint-match.pdf`
- **Size**: 1,059 bytes (~1KB) - well under 50KB threshold
- **Expected content**: Single word "Test" (from `fingerprint-match.txt`)
### ✅ PASS: Confirm the selected file exists and is readable
- File exists: ✓
- Readable permissions: ✓ (`-rw-r--r--`)
- Valid PDF header: ✓ (starts with `%PDF`)
- Exact size: 1,059 bytes
## Documentation for Subsequent Beads
**Chosen fixture path**: `tests/fixtures/encoding/fingerprint-match.pdf`
This fixture will be used for all subsequent child beads requiring a small, fast encoding test fixture.
## Rationale for Selection
- **Size**: 1KB - minimal overhead for fast test execution
- **Simplicity**: Extracts to single word "Test" - easy to verify correctness
- **Purpose**: Designed for font fingerprint matching tests (Phase 2.2 Level 3)
- **Consistency**: Recommended by task description
## Test Environment
- Working directory: `/home/coding/pdftract`
- Fixture path: `tests/fixtures/encoding/fingerprint-match.pdf`
- Fixture absolute path: `/home/coding/pdftract/tests/fixtures/encoding/fingerprint-match.pdf`
## Verification Commands Executed
```bash
# List directory
ls -lh tests/fixtures/encoding/
# Verify file size and permissions
ls -lh tests/fixtures/encoding/fingerprint-match.pdf
# Verify PDF magic bytes
head -c 4 tests/fixtures/encoding/fingerprint-match.pdf
# Get exact size
stat -c %s tests/fixtures/encoding/fingerprint-match.pdf
# View expected content
cat tests/fixtures/encoding/fingerprint-match.txt
```
## Conclusion
All acceptance criteria PASS. The fixture `tests/fixtures/encoding/fingerprint-match.pdf` is confirmed to exist, be readable, be a valid PDF, and meet the size requirements for fast execution.

# bf-okdnk: CMAP Output Parsing
## Summary
Extended the CMAP unmapped glyph test from bf-4y66q to access and parse the generated CMAP output structure.
## Implementation
### 1. Added `iter()` method to `ToUnicodeMap`
**File:** `crates/pdftract-core/src/font/cmap.rs`
Added a public iterator method to `ToUnicodeMap` that allows tests (and other code) to iterate over all CMAP mappings for inspection:
```rust
pub fn iter(&self) -> impl Iterator<Item = (&Vec<u8>, &Vec<char>)> {
self.mappings.iter()
}
```
This returns an iterator over `(source_bytes, target_chars)` pairs.
### 2. Extended tests to show CMAP contents
**File:** `crates/pdftract-core/tests/cmap_unmapped_glyphs.rs`
Extended two tests to demonstrate CMAP output structure access:
- `test_cmap_unmapped_glyph_skip`: Shows basic single mapping with detailed debug output
- `test_cmap_multiple_mappings_with_unmapped_check`: Shows multiple mappings with compact debug output
Both tests now include inspection sections that display:
- Source bytes in hex format
- Target characters as strings
- Unicode code points
- Total mapping count
## Verification
### Test Results
Both extended tests pass successfully:
```
=== CMAP Output Structure Inspection ===
Source bytes: [00]
Target chars: "A" (Unicode: [0041])
Total mappings: 1
=== End CMAP Inspection ===
=== CMAP Multiple Mappings Inspection ===
[[02]] → C
[[01]] → B
[[00]] → A
Total mappings: 3
=== End Inspection ===
```
### Acceptance Criteria
- ✅ Test can access CMAP output structure - `iter()` method provides access
- ✅ Test compiles without errors - All code compiles
- ✅ Test runs to completion - Tests pass without hanging or failing
- ✅ CMAP contents are visible for inspection - Debug output shows all mappings
## Artifacts
- Modified: `crates/pdftract-core/src/font/cmap.rs` (added `iter()` method)
- Modified: `crates/pdftract-core/tests/cmap_unmapped_glyphs.rs` (extended two tests)
