+**The phases are event-delimited and decay-timed, never clocked.** A phase has no fixed duration.
+The action is the boundary where preparation ends and behaving begins; the fast trace's decay below

+actions — a component's refractory-like period, whether literal refractoriness at the soma or the

+the firing pattern. A fast train compresses preparation to nothing (no time to refill: depression);
+sparse action gives preparation its full extent. Timing here is chemistry, not a timer (category V).
 
-## X. The Logic of NIGHT — Inward Negotiation in Three Phases
+**Evaluation and preparation share the fast trace but send it two ways.** The same trace the action
+deposits is read by both: evaluation reads it for *significance* (climbing toward the tag, for the
+other scope), preparation reads it for *readiness* (tuning the next action's timing and thresholds,
+in this scope). The soma makes this visible — its nuclear-calcium climbs toward the tag
+(evaluation), while its inactivation, adaptation, and alignment traces tune the next spike
+(preparation) — all from the one spike's deposit. Evaluation looks up and across scopes; preparation
+looks around the ring to the next action.

+**The two turnings are stitched together by evaluation.** Each scope's EVALUATION mints the token
+the *other* scope's PREPARATION consumes: day-evaluation mints the tag, night consolidates it;
+night-evaluation mints the structure, the next day reads it. The tag is information becoming a
+resource-claim; the structure is resource becoming the bound on future information-gathering. The
+DAY/NIGHT alternation is therefore not two separate cycles but *one ring turned in two directions*,
+handing off to itself through evaluation — tag outbound to the night, structure outbound to the day.
+The fatigue loop (category II) switches which way the ring is turning; the evaluation handoff passes
+what crosses when it turns. Switch and payload, one ring, two turnings.
+
+**Why night must cycle its turnings.** By day the ring turns once per action and the actions come
+whenever the world drives them. By night the turning repeats in rounds because coherence is reached
+by different components at different times: a component that finds no coherent peers in one round's
+ACTION draws nothing in its EVALUATION, holds its tag, returns its resource to the pool for peers
+that did cohere, and turns again — its PREPARATION making room for a retry. Deferral is free because
+evaluation only spends when coherence is found, and energy, the irreversible currency (category IV),
+is burned only at the moment of coherent commitment. So the night is many turnings of the one ring,
+converging as coherence spreads, ending when demand is discharged or the night's energy is spent —
+and a change that never coheres before its tag decays is simply never spent on, which is how the
+turning forgets.
