10.7 SCoLT: the Toulmin specialization

The Toulmin application provides the clearest specialization. The Sheaf Chain of Toulmin Thought, SCoTT, supplies the base argument sheaf: local tickets contain claims, grounds, warrants, backing, qualifiers, rebuttals, and source bindings, and descent asks whether they glue. We call the CoLT architecture specialized to this argument sketch SCoLT, the Sheaf-theoretic Chain of lincs Thought:

\[ \mathrm{SCoLT} = \mathrm{CoLT} (\mathbb S_{\mathrm{Arg}}, \mathcal T_{\mathrm{Arg}}, \mathcal U_{\mathrm{Arg}}, \mathcal R_{\mathrm{Arg}}, \mathcal A_{\mathrm{Arg}}). \]

SCoTT is therefore the base sheaf-theoretic construction inside SCoLT. SCoLT adds tangent stability, localization, governed repair, and admission.

Argument component	CoLT role	Typical tangent or repair question
Claim	Maintained proposition with scope	Does paraphrase or context change silently strengthen it?
Ground	Evidence-bearing local section	Does removing or replacing one ground expose an unsupported route?
Warrant	Typed bridge from ground to claim	Is the bridge stable, sourced, and applicable in this context?
Qualifier	Boundary of licensed generality	Must the claim be weakened after transport?
Rebuttal	Registered counter-condition	Was an exception discharged, preserved, or silently erased?
Source binding	Provenance morphism	Does restriction preserve the evidence that licensed the step?
Global argument	Effective glued realization	Do locally coherent tickets form one admissible argument?

Table 10.2 SCoLT instantiates the general CoLT transition with Toulmin-typed argument structure.

Chapter 19 develops this specialization and its initial structural evaluation.
