-These five need no registry, no definition, no history — they are
-structure itself: nothing, unity, negation, and the two endless ends.
-They may appear bare anywhere.
+The space is bounded — nothing exceeds −1 or +1 — but between them
+lies an uncountable infinity of positions, 0 among them. That interior
+infinity is a constant too: structure itself, not something anyone
+invented. These may appear bare anywhere in code.
 
-Everything else is **not a constant and must never be invented as one.**
-Inventing numbers is how systems rot: someone types `0.73`, someone
-else copies it, soon it's load-bearing folklore nobody can explain.
