Use when implementing a non-trivial feature, migration, or refactor that would otherwise be a single large change. Activate for keywords like "feature flag", "incremental", "vertical slice", "migration", "rollout", "behind a flag", "ship small". Enforces vertical slicing, feature-flagged rollout, and refactor-with- evidence (behavior-preserving changes proved by test/perf deltas). Always ship the smallest reversible change -- never bundle unrelated improvements.
