Principlev1
Preserve the first and last links of a normal chain when
Preserve the first and last links of a normal chain when designing emergency variants, compressing only the middle section, to maintain identity signals and reduce activation cost.
Why This Is a Principle
Derives from When a habit forms, neural activity spikes at the cue and (neural activity spikes at start/end of chains), Dopamine neurons encode prediction error rather than (dopamine encodes prediction error/expectation), and Habits as Context-Response Associations (habits as context-response associations). The principle prescribes preserving chain anchors even in emergency versions to maintain the reward signal and familiar activation pattern. Actionable design guidance, not an axiom.
