Ship behind a flag, roll out by rule.

• Rules, not expressions

  A rule is a structured comparison — attribute, operator, value — and the first matching rule wins.

• Gradual rollouts

  A rule can roll out by percentage; 100 is the default.

• Evaluate, and see why

  One call evaluates a set of flags for a context and returns the value with the reason it matched — targeting_match or default.
