⧉ portal:esp32-01 — the two-faced portal cell (P ↔ U)
Both faces persist, both attributed, both stamped (A10). The seam is a diff — derived, never authoritative. Rendering never overwrites.
face.out is spoken by P in U0 (the laptop's deflated summary);
face.in is spoken by U in U1 (carried up over the link). From inside U1, face.out is
a rumor about itself. Navigation is unaffected by disagreement — you can still route to
S2 through a portal whose faces are at war (A8, A9).
