Change → production workflow (solo-fast)

Goal: ship a change safely while keeping “green main” as the deploy gate.

Canonical references:

• Docs guidelines: ../../documentation-guidelines.md
• Monitoring/CI gate: ../../operations/monitoring-and-ci-checklist.md
• Deploy playbook (VPS): ../../operations/playbooks/core/deploy-and-verify.md

Workflow

1. Make the change locally.
2. Run checks:
3. make check
4. Commit and push.
5. Wait for CI to pass on main.
6. Deploy on the VPS using the deploy playbook.

Cross-repo guardrails

• If you add/change a user-facing frontend route that is part of the production “public surface”, update:
• scripts/verify_public_surface.py
• Frontend bilingual rules: ../../frontend/i18n.md
