jedarden b970bc2d66 feat(bf-2f5ew): add Tier 4 competitive benchmark runner and results structure 
- Create benches/results/.gitkeep and README.md
- Create benches/competitors/run_all.py Python orchestration script
- Script runs competitor benchmarks (pdftract, pdfminer.six, pypdf, pdfplumber)
- Emits benches/results/<commit-sha>.json with throughput metrics
- Add tier4-competitor-runner to pdftract-ci Argo WorkflowTemplate
- Runs only on main branch to track performance over time
- Acceptance criteria: ratio_pdfminer ≥ 10.0, ratio_pypdf ≥ 5.0

bf-4n1w3: Add inspection command examples to no-mapping documentation

Work Completed

Changes Made

Added comprehensive inspection command examples to tests/fixtures/no-mapping.md:

New Sections Added:

  1. Advanced Object Inspection - pdftk commands for object analysis
  2. Encoding Dictionary Deep Dive - Extract full encoding dictionary with all 10 glyph names
  3. Content Stream Hex Analysis - Show hexadecimal content codes
  4. Cross-Reference Table Analysis - Verify PDF structure integrity
  5. Embedded File Check - pdfdetach command (confirms no embedded files)
  6. Digital Signature Check - pdfsig command (confirms no signatures)
  7. Metadata Stream Check - Verify no XMP metadata present
  8. Page Boundary Inspection - Extract MediaBox, CropBox, etc.
  9. PDF Version and Header - Verify PDF version and EOF marker
  10. Quick Reference Script - Comprehensive all-in-one verification command

Bug Fix:

  • Fixed file size inconsistency (line 111): changed File size: 660 bytes to File size: 718 bytes to match actual fixture

Verification

Before (existing content):

  • ✅ pdfinfo example with output (lines 457-478)
  • ✅ pdffonts example with output (lines 480-493)
  • ✅ pdfimages example with output (lines 575-587)
  • ✅ Comprehensive troubleshooting section (lines 588-751)

After (added content):

  • ✅ 9 additional inspection command examples with expected output
  • ✅ Quick reference script for complete fixture verification
  • ✅ All commands tested and verified on actual fixture

Commands Tested and Verified

# Verified fixture state
pdfinfo tests/fixtures/encoding/no-mapping.pdf
# Output: 718 bytes, PDF 1.4, 1 page

pdffonts tests/fixtures/encoding/no-mapping.pdf  
# Output: CustomNoMap Type 1 Custom encoding

# File integrity
ls -lh tests/fixtures/encoding/no-mapping.pdf
# Output: 718 bytes
sha256sum tests/fixtures/encoding/no-mapping.pdf
# Output: 7ac6a154454db712848ba780d7970bc2442f7009be043f8acbfe3e3b92f25e61

Acceptance Criteria Status

Criterion Status Notes
Documentation includes example pdfinfo command with output ✅ PASS Lines 457-478, verified actual fixture
Documentation includes example pdffonts command with output ✅ PASS Lines 480-493, verified actual fixture
Additional inspection tools documented ✅ PASS Added 9 new tools: pdftk, pdfdetach, pdfsig, hexdump, file, strings, mutool, etc.
Tips for common issues included ✅ PASS Comprehensive troubleshooting section already existed (lines 588-751)

Git Commit

Commit: 4d78a9d2
Message: docs(bf-4n1w3): add comprehensive inspection command examples to no-mapping.md

Files Modified:

  • tests/fixtures/no-mapping.md (+434 lines, -10 lines)

Push Status

⚠️ Push to forgejo remote failed with HTTP 413 (payload too large)

Cause: 145 commits ahead of github/main combined with large working directory changes causes push failure.

Mitigation: Commit exists locally and is valid. Push failure is infrastructure-related, not a commit quality issue. The commit follows all requirements:

  • Conventional Commits format: docs(bf-4n1w3): ...
  • Proper file scoped to documentation only
  • All acceptance criteria met

Next Steps: Git repository maintenance needed (force push or rebase) to clear the 145-commit backlog, but this is outside scope of this bead.

Documentation Quality

The added commands provide:

  • Progressive complexity - from basic pdfinfo to advanced hex analysis
  • Expected output - every command shows what to expect
  • Troubleshooting value - helps verify fixture integrity during development
  • Tool alternatives - shows both pdftk and strings/grep approaches
  • Comprehensive coverage - covers fonts, encoding, content streams, structure, metadata

Total documentation now provides complete fixture inspection guidance for both quick verification and deep analysis.
