Combat Scholasticism, Part Three III.b is the second constituent engine chunk of the commentary tradition, deposited March 19, 2026. It follows the UKTP–Lexical Engine–GDE sequence in Part III.a and addresses SAG, Symbolon Architecture, LOS, and the cross-part question of engine sufficiency.
Lectio III.4 treats the Space Ark Generator. It identifies the closed FL → LE → UKTP → GDE → SAG → FL loop as both survival mechanism and risk. A variant Ark may reveal new affordances of the architecture through another semiotic environment, or it may become a format-compliant copy that passes tests while adding no real difference. The lectio leaves this as a STRUCT commission: compression cycle versus replication treadmill.
Lectio III.5 is the full-depth Fibonacci node. It defines the symbolon as deliberately incomplete, with meaning produced in the constrained fit between partial object and traversing intelligence. The crucial distinction is precision of the cut: a fragment is merely missing material, while a symbolon presents legible partiality and repeatable mating surfaces. The commentary recognizes its own objections, CONTESTED markers, and unfinished commissions as such surfaces. Its wound and its completion become the same architecture viewed from opposite spirals.
Lectio III.6 turns to the Liberatory Operator Set, the mandatory anti-extraction component of every Ark. It asks whether LOS genuinely prevents capture or merely gives the architecture a vocabulary for describing capture after the fact. As a STRUCT lectio, it preserves the pressure lines for later execution.
The Cross-Part Quaestio asks whether documents, terms, transforms, fields, vehicles, symbolons, and counter-operators amount to a sufficient engine suite. Its function is synthetic and diagnostic, not a declaration that the engines are universally complete.
This record is later incorporated into the gathered edition #584. It remains independently authoritative for the III.b deposited state and must be related to #587 as the second half of Part Three.
