• Documents internal/ package structure (common, smtp, imap, pop3, jmap)
• Updated integration test architecture (11 tests, interactive + automated)
• Current file organization (cmd/, internal/, src/)
• Build system documentation (build-all.ps1, GitHub Actions CI/CD)

• Updated to version 2.6.11 and date 2026-01-31

File Cleanup

✅ Renamed integration test file for consistency:

• src/msgraphgolangtestingtool_integration_test.go → src/msgraphtool_integration_test.go

✅ Removed obsolete files:

• IMPLEMENTATION_STATUS.md (outdated implementation tracking)
• IMPROVEMENTS.md (superseded by changelog)
• INTERACTIVE-RELEASE-DRYRUN-EXAMPLE.md (no longer relevant)
• REVIEW_TASKS.md (tasks completed)

Bug Fixes

✅ Fixed formatting issue in .github/workflows/build.yml (line 134)

Code Review - PR #40

CRITICAL BUG FOUND in .github/workflows/build.yml line 134:
The line has an erroneous ' 7' at the end which will break Windows builds.

REQUIRED FIX: Remove the ' 7' from:
Get-Item (matrix.zip_name) | Select-Object Name, Length 7

STRENGTHS:

• Updated ARCHITECTURE_DIAGRAM.md reflects all 5 tools accurately
• Removed 4 obsolete documentation files (3,207 lines cleaned up)
• Integration test file renamed for consistency

OBSERVATIONS:

• Build workflow changed from wildcard to explicit file names (good for stability)
• No security concerns (documentation only)
• No performance impact (documentation only)
• Follows semantic versioning and AGENTS.md conventions

RECOMMENDATION: Fix the syntax error before merge, then this PR is ready.
