Its path category Cert has these states as objects and finite composable paths as morphisms. The empty path is an identity, and composition is concatenation. One may further identify paths by a declared congruence compatible with concatenation. Associativity and the identity laws then hold by construction.

    [Certificate] A certificate for a nonempty requested target set T_0⊆ V is a pair C=(K,H), K⊆ V, H⊆ J^cert, such that A∪ T_0⊆ K and T_0⊆ D_cert(K,H). Order certificates componentwise: (K,H)≤(K^prime,H^prime) means K⊆ K^prime and H⊆ H^prime. A least certificate is contained in every certificate for the same request. Minimizing only the node set, only the justification set, or a numerical cost is a different objective.

    A trace σ=(j_1,…,j_k) is a list of rule addresses. Replay begins with the list K_0=Lmathbin+ +S. It rejects an unknown rule address or a step whose premises are not all known. Otherwise it adds the conclusion. Strict replay additionally requires the conclusion to be new. Causal replay permits a conclusion already known.

If the total is zero, nonnegativity makes every contribution in that coordinate zero. The implementation records normalized loss zero there as a convention, rather than dividing by zero.

    A practical stopping rule selects the first depth satisfying r_d≤ε or fracr_d-1-r_dc_d-c_d-1<τ. The first condition uses a declared tolerance. The second applies only at d≥1 with c_d>c_d-1 and compares the most recent reduction with its extra cost. Zero-cost refinements require separate handling. These stopping rules do not generally minimize J_g over all remaining depths.

    The strict Komorebi realization is now an actual set of coherent local models, Γ( M_F)= {(X_U)_U:ρ_U,W(X_W)=X_U whenever U⊆ W}. There is an explicit bijection Models(F)≃Γ( M_F), X⟼(X∩ U)_U. Its inverse evaluates a coherent family at the full patch V. Coherence shows that every other component is precisely the restriction of that value. The Lean declaration pathProofPath.Field.modelEquivSections constructs this equivalence, using pathViewDiagram and the actual local restriction maps.

    A refinement preserves the certified target on its declared scope. Preservation of other tasks requires a separate recovery condition. Let R_d:mathscr A→ R_d be the representation scheme at depth d. A sufficient condition is a map π_d:R_d+1(mathscr A)⟶ R_d(mathscr A) with R_d=π_d∘ R_d+1. If a task factors as q=d_q∘ R_d, then q=(d_q∘π_d)∘ R_d+1. Hence R_dpreceq_ QR_d+1. Repeated refinements satisfying this condition give the recoverability chain. For a restricted task family, preserving its suppo…

    A practical stopping rule selects the first depth satisfying r_d≤ε or fracr_d-1-r_dc_d-c_d-1<τ. The first condition uses a declared tolerance. The second applies only at d≥1 with c_d>c_d-1 and compares the most recent reduction with its extra cost. Zero-cost refinements require separate handling. These stopping rules do not generally minimize J_g over all remaining depths.

    Take a proof object with exactly two available depths d_1<d_2, with r_d_2<r_d_1 and c_d_2>c_d_1. Direct subtraction shows that d_2 is preferred exactly when α_g(r_d_1-r_d_2)>β_g(c_d_2-c_d_1). The goal (α_g,β_g)=(1,0) strictly prefers d_2, whereas (0,1) strictly prefers d_1. Since these are the only available depths, each preference is a global optimum.

    A simple audit priority score is P(x) = fracp_err(x) c_consequence(x) (1+r_dependency(x)) c_audit(x). Here p_err(x)∈[0,1], the consequence and dependency factors are nonnegative, and c_audit(x)>0. Zero-cost checks can be handled separately.

    luations of reviewer i under two labels. In a finite set of N reviewers, assign exactly n_1 to the first label and n_0=N-n_1 to the second, uniformly over assignments with those sizes, where n_0,n_1>0. Assume each observed response equals the potential response under its assigned label and does not depend on other assignments. Then the difference of the two sample means is unbiased for N^-1∑_i(Y_i(1)-Y_i(0)). Indeed, each reviewer has inclusion probability n_1/N in the first mean and n_0/N in th…

    For n=1, the effective count is one. At the excluded boundary ρ=-1/(n-1), the mean has zero variance and there is no finite variance-equivalent count. For fixed 0<ρ≤1, n_eff→1/ρ as n→∞. Negative correlations can give n_eff>n, but a fixed negative correlation is not admissible for arbitrarily large n.

Its inverse evaluates a coherent family at the full patch V. Coherence shows that every other component is precisely the restriction of that value.

    Proof Path Theory studies this larger object without changing the standard of proof. Its central separation is certificate of validity ≠ expanded discovery field. The certificate answers whether the conclusion follows. The discovery field records how the conclusion became reachable, what alternatives were considered, what was lost during compression, and which omitted structures may matter later.

    es:7:11 Let C:A→ B. Every predicate q:A→Prop factors through C if and only if C is injective. If C is injective, define the decoder of q at b by the predicate ∃ a (C(a)=b and q(a)). At b=C(a_0), injectivity makes this equivalent to q(a_0). Conversely, if C(a)=C(a'), use the predicate q(z)≡(z=a). Its decoded values at the equal encodings must agree, giving a'=a. This is the general collision criterion specialized to all predicates.

    For each candidate x∈ C, let R_x⊆ F be the set of future targets reachable from M∪{x}. Let R_M be the targets already reachable from M. Reachability from a union of starting nodes is the union of their individual reach sets, so U_M(S)= ∑_f∈ R_M∪⋃_x∈ SR_xw_f. Adding a candidate cannot remove a reachable target, so U_M is monotone.
