Quality Playbook

HARD-GATE

• All quality commands (mix format --check-formatted, mix credo --strict, mix dialyzer, mix hex.audit, mix test) must exit 0 before a PR is opened.
• Any refactor requires green characterization tests and explicit user approval.
• No gate may be skipped or declared green from simulated output.

When to use

Before opening a PR or when asked for a full quality/production-readiness pass.
