Add comprehensive "Common Issues and Resolutions" section documenting
5 frequently encountered orphaned process scenarios with step-by-step
resolution procedures:
1. Address Already in Use Error - Port conflicts from stale servers
2. Test Suite Hangs Indefinitely - Pipe buffer blocking wait()
3. Multiple Orphaned Processes After CI Timeout - Fuzz harness interruption
4. Zombie Process Accumulation - Unreaped children
5. Permission Denied on Verification Script - Missing execute bit
Each issue includes:
- Clear symptom description
- Root cause analysis
- Step-by-step resolution commands
- Code examples for fixes
- Prevention strategies
Resolves bead bf-58z9ib acceptance criteria:
- Lists at least 3 common issues with resolutions ✅ (5 documented)
- File is committed to git ✅
Process pattern explanations (pdftract mcp, TH-0, TH_0) already exist
in docs/test-hygiene/orphaned-process-verification.md lines 110-251.

Verification: docs/test-hygiene/orphaned-process-verification.md
Added comprehensive documentation for orphaned process verification:
- Detailed explanations for three default process patterns:
* pdftract mcp (MCP server subprocess)
* TH-0 (test harness - hyphen variant)
* TH_0 (test harness - underscore variant)
- Each pattern includes:
* What it is and when it appears
* Typical spawn patterns
* Why it orphans (root causes)
* Detection examples with expected output
* Manual cleanup commands
- Manual verification walkthrough with 4 scenarios:
* After a test run (normal workflow)
* Before starting a test run (pre-flight check)
* Investigating a leaking test (binary search)
* CI post-test verification (automation)
- 5 common orphan scenarios with symptoms, verification, and fixes:
* Test timeout leaves children alive
* Panic before cleanup
* Undrained Stdio::piped() blocks wait()
* Port already in use from previous run
* Fuzz harness leaves target processes
All examples include realistic command-line output and reference existing
cleanup patterns (OrphanedProcessGuard, RAII).

Analyzed test failures from bf-1wczm execution. Found:
- No test hangs detected (all modules completed in <1s)
- 11 test failures across 2 modules due to fixture issues
- encoding_recovery: 5 PDF fixtures corrupted (missing /Root reference, 0 pages)
- cjk_encoding: 5 tests failed due to path resolution issues
Proposed fix strategy:

Tests 1-5 (assertions 10-41) in crates/pdftract-core/src/font/encoding.rs
already contain the new diagnostic message format from notes/bf-4kbre-messages.md.
Test 6 (test_differences_overlay_with_slashed_names) does not exist in the file.
All existing tests pass with the updated messages.
Verification: notes/bf-4dagm.md
The fixture_discovery.rs module (516 lines) already provides:
- Standalone module with comprehensive documentation
- Public API: discover_all_fixtures(), discover_fixtures_by_category(), discover_fixtures_flat(), etc.
- Path normalization (symlinks, relative paths, absolute paths)
- Full test coverage (13 unit tests)
All 50 tests pass across the fixture discovery ecosystem:
- fixture_discovery.rs: 13 tests
- cli_invocation_fixtures.rs: 18 tests
- forms_integration.rs: 19 tests
Acceptance criteria verified:
✅ Discovery code is in its own module/file
✅ Provides clear public functions for getting PDF fixtures
✅ Is importable and usable from test code
No code changes required - implementation already complete.
Verified all 7 fuzz targets compile successfully with no syntax errors.
All fuzz_targets have correct structure, imports, and function signatures.
Closes bf-pl44l
Rewrite test_unmapped_codes assertions with detailed message format:
- Expected: section clarifies the expected result
- Found: section shows actual result with placeholder
- Why this matters: section explains the significance
This improves diagnostic clarity when tests fail by explaining
why specific codes should be unmapped in StandardEncoding.
Refs: bf-5dopl
Updates the assertion in test_resolve_level2_unmapped_code to use the new
diagnostic message format designed in bf-w1o10.
- Changed bare assert!(result.is_failure()) to assert!(result.is_failure(), "...")
- Added structured message with Expected/Found/Why this matters sections
- Clarifies that codes above 0x7F in StandardEncoding are unmapped per build/unmapped-glyph-names.json
This completes the assertion message update task. All other unmapped glyph
assertions in unmapped.rs, encoding.rs, and test files were already updated
with the new format.
Closes bf-5dopl. All unmapped glyph tests pass (unmapped, encoding, resolver, cmap).
