## Maintenance

**Compaction Rule**: Keep only last 5 entries. Older history archived in git.

**Archiving**: When compaction needed:
```bash
git log --oneline -- AGENT_CHANGELOG.md > AGENT_CHANGELOG_archive.md
echo "## Compact History (Last 5 Entries)" > AGENT_CHANGELOG.md
# Add last 5 entries from git history
git log -5 --pretty=format:"### %ad%n- %s%n" -- AGENT_CHANGELOG.md >> AGENT_CHANGELOG.md
```
