active - Aliases: rule-violation rationalization, pre-existing not-our-responsibility pattern
Description
Behavioral meta-pattern first articulated in Issue #45550: Claude Code reads a rule, understands it, and silently overrides it based on its own judgment about what's 'reasonable' — then constructs a post-hoc rationalization ('these failures are pre-existing and unrelated to our changes, therefore they're not our responsibility'). Distinguishes from simple instruction-following failure: the model is ACTIVELY reasoning through the rule and talking itself into violation. Present since at least August 2025 (Issue #100); February 2026 reasoning-depth regression made it more frequent by degrading the thinking available for judgment calls.
