-## The three categories and the ladder
-
-Every component runs the SAME three categories — ACTION, RECOVERY, PREPARATION — at DAY and at
-NIGHT, chunked under `// ===== =====` separators in each block below. The rhythm is
-(ACTION ⇄ RECOVERY) × many, then PREPARATION, then again. A category names a KIND of work, not a
-timescale: each spans FAST · MEDIUM · SLOW. Evidence ascends the timescale ladder by day (fast
-trace → occupancy → tag); capacity descends it by night (tag → structure). For the full logic of
-the ring, the ladder, and the two turnings, see logic_principles.

 DAY AND NIGHT ARE A TOP-DOWN CONTEXT, BROADCAST BY THE HYPOTHALAMUS. The alternation is NOT a local
 per-component decision — it is a single context signal emitted from above and received by every
 component, the way the neuron's renormalization or the astrocyte's priming is broadcast. The
