Week 4 — ship?

Yes. Day 22: feature-freeze, run the full test suite, run the security-review skill. Day 23: write the CHANGELOG.md via /release-notes, bump SemVer in composer.json. Day 24: tag, push to GitHub, build the Composer package or Marketplace ZIP. Day 25: deploy to staging, run smoke tests by hand. Day 26: production deploy via your existing DEPLOYMENT.md flow, monitor for 24h. Day 27–28: write a retrospective — what worked, what didn't, what goes into the next CLAUDE.md. Day 29–30: open-source the slash-commands and sub-agents you built — you'll thank yourself in 6 months.
