| Φ: X → ℝd | Decoding map: for an admissible specification, the system reliably recovers the intended meaning; Φ belongs to the decoding system and does not depend on i (B.1); below the bar no decoded intent stands (§5.1). |
| (x̃) ≔ Φ(x) ∈ ℝd | Decoded intent, with ‖(x̃) ‖ > 0 on admissible episodes; the content the system works from, parallel to the criterion x* = Γ(x) (B.1). |
| Ψ:(0, ∞) × ℝd → ℝd | Execution map: R(S) ≔ Ψ(S,(x̃); no structural form assumed beyond the regularities of B.2 (B.1). |
| [Smin, Smax] | Operating range, 0 < Smin ≤ Smax; the regularities of B.2 are assumed only on this range (B.2). |
| λQ > 0, εQ ∈ [0,1) | Per-unit rate and relative error bound of quality-magnitude scaling with its zero branch (B.2). |
| ηQ (S, x̃) | Relative quality deviation, ∥ Π Q ( R ( S ) ) ∥ λ Q S ∥ Π Q ( x ˜ ) ∥ − 1 , defined for ‖ΠQ (x̃) ‖ > 0; the assumption reads |ηQ| ≤ εQ; audited in B.4 (B.2). |
| λT > 0, εT ∈ [0,1) | Per-unit rate and relative error bound of nondegenerate directional scaling with its zero branch (B.2). |
| ηT (S,(x̃) | Relative directional deviation, ∥ Π T ( R ( S ) ) − λ T S Π T ( x ˜ ) ∥ λ T S ∥ Π T ( x ˜ ) ∥ ; the assumption reads ηT ≤ εT; audited in B.4 (B.2). |
| uS, u0 | Unit directions of ΠT (R(S)) and of ΠT (x̃); ‖uS − u0 ‖ ≤2εT on the range (B.3). |
| S req ≔ θ Q λ Q ∥ Π Q ( x ˜ ) ∥ | Nominal required scale at which the quality magnitude reaches θQ; bracketed by the sufficient and necessary levels of B.3 (B.3). |
