Read from the holographic externality, the substrate's decoherence (endo) becomes coherence (exo = 1 − endo). The map x → 1 − x reflects about the fold at y = 0.5; the dyad (2) is its single fixed point — the one value both frames read alike.
The epistemic projection registers not at the origin but at the 5th wall: a +4 drift seats the axiom (1.0) on value 5. Values 1–4 are pre-epistemic; the projection overhangs to 68, four past the 8×8 ceiling.
In real physics the present has duration, so the substrate re-emits from every node (each a dyadic lock). Since decoherence never exceeds the dyad (0.5), the thick present fills the whole subspacetime below the fold; the thin curve is only its knife-edge idealization.
Stretch the projection ×1…×k from the origin (x → k·x). The x=12 feature (the exo of value 8) walks 12, 24, 36, 48, 60… — at ×5 it lands on 60 = 64 − 4, flanking the ceiling opposite the 68 overhang. Sweep k to read the landings.
The thick-present dots projected outward (x = Z·v) and lifted (cumulative → 0.75), overlaid with all of §7.6 (the exo curves, the x=12 trajectory, the 60·64·68 references). Scale 8 reaches 512 (dots) / 544 (exo) — the bit-length of the P field. 17 & 19 are the two domain-column channels (the gaps): 19 establishes the domain column; 17 is locked, subject to its externality.
