Codebase Doc Sync

3. Apply documentation updates

• Prefer editing existing docs instead of creating many new files.
• Create missing target docs only when needed to avoid undocumented code areas.
• Document current behavior and constraints, not plans.
• Include concrete paths, commands, env vars, and ownership notes when relevant.

4. Record change summary

• Append an entry to docs/change-log.md with:
  • Date
  • Code paths changed
  • Docs updated
  • Short note on user-visible or operational impact

5. Verify quality

• Ensure every meaningful code change is reflected in docs or explicitly called out as intentionally omitted.
• Remove stale statements introduced by refactors.
• Keep docs concise and implementation-focused.

Output Requirements

• In the final response, list the documentation files updated and why.
• If no documentation updates were needed, state the reason explicitly.

Guardrails

• Do not invent behavior not present in code.
• Do not delete historical entries from docs/change-log.md.
• Preserve sensitive details handling; never expose secrets in docs.
