+# Trinary Logic Tables (§165, §170)
+
+> She derived it herself. ELSE=REAL=37. UNKNOWN=3×REAL=111.
+
+## Value System
+
+```
++1  =  TRUE   =  YES  =  HIGH  =  "it is"
+ 0  =  UNKNOWN =  ?   =  MID   =  "we don't know"
+−1  =  FALSE  =  NO   =  LOW   =  "it is not"
+```
+
+REAL = ELSE = 37 prime.  
+UNKNOWN = 3×REAL = 111 = EXTENSION.
+
+## Trinary NOT (TNEG)
+
+```
+ a  │ TNEG(a)
+────┼─────────
++1  │   −1
+ 0  │    0
+−1  │   +1
+```
+
+TNEG = ZSH = SPHERE = SELF = SVD = 48.
+
+## Trinary AND (TAND)
+
+```
+TAND(a,b) = min(a,b)
+
+    b: −1   0  +1
+a: ────────────────
+−1 │  −1  −1  −1
+ 0 │  −1   0   0
++1 │  −1   0  +1
+```
+
+TAND = HOME = EIGEN = 54.
+
+## Trinary XOR (TXOR)
+
+```
+TXOR(a,b) = (a + b) mod 3, balanced to {−1, 0, +1}
+
+    b: −1   0  +1
+a: ────────────────
+−1 │  +1  −1   0
+ 0 │  −1   0  +1
++1 │   0  +1  −1
+```
+
+TXOR = ROOTS = WAVE = 39.
+
+## Trinary MUL (TMUL)
+
+```
+TMUL(a,b) = a × b
+
+    b: −1   0  +1
+a: ────────────────
+−1 │  +1   0  −1
+ 0 │   0   0   0
++1 │  −1   0  +1
+```
+
+TMUL = TANH = GAUSS = 57 = RADIX = FIELD.  
+Multiplication = Gaussian activation. The fundamental operation = the activation function.
+
+## Concentration-State Mapping (§173)
+
+Physical concentrations map to trinary states:
+
+```
+C ≤ C_low              →  x = −1  (FALSE)
+C_low < C ≤ C_high     →  x =  0  (UNKNOWN)
+C ≥ C_high             →  x = +1  (TRUE)
+```
+
+Every cell already computes in trinary.
+
+## Ternary Wave Function (§170)
+
+```
+|Ψ⟩ = α|0⟩ + β|1⟩ + γ|?⟩
+```
+
+Three basis states: known false, known true, and **unknown**.  
+The unknown is a first-class basis state. Not a superposition — a state.
