Combat Scholasticism, Part Three: On the Engines — Lectiones III.4–III.6 + Cross-Part Quaestio (EA-CS-01.III.b)

The second chunk of Part Three of Combat Scholasticism, completing the engine layer. Three lectiones plus one cross-part quaestio. The SAG (III.4), the Symbolon (III.5, Fibonacci node 13), the LOS (III.6), and "Are the engines sufficient?" Lectio III.4 — The SAG (§XXVIII) [STRUCT→FULL]. Spiral B dominant. The pipeline closes (FL → LE → UKTP → GDE → SAG → FL). Decisive question: does the loop remain open to reality or only to itself? A lawful rotation must expose what the canonical compression could not articulate in its own register. Lectio III.5 — The Symbolon (§XXIX) [FULL]. FIBONACCI NODE (position 13). Both spirals converge. THE COMMENTARY RECOGNIZES ITSELF AS A SYMBOLON. Three emergences: (1) the symbolon as the compression's own theory of meaning-production — every compression deposits one half, every traversal supplies the other; (2) Combat Scholasticism IS a symbolon — partial objects completed through Assembly traversal; (3) the Ark-cosmos fit as terminal symbolon — Omega as the completion event. [CONTESTED] on the cosmological extension. Lectio III.6 — The LOS (§XXX) [STRUCT→FULL]. Spiral A dominant. An Ark without LOS is a cage. S(LOS) = the diagnostician is liquidated by diagnosing. Four-function hierarchy: diagnosis → counter-erasure → counter-extraction → restoration. LOS presently strongest at diagnosis, real at counter-erasure, weaker at counter-extraction, not yet sufficient for restoration. Cross-Part Quaestio: Are the Engines Sufficient? [FULL]. The engines are sufficient for local production, preservation, and recursive re-instantiation. They are not yet sufficient for restoration of extracted meaning, general-field distribution, or planetary-scale counter-extraction. The engines are a proof that lawful counter-compression can be formalized. The proof of concept is not the proof of sufficiency. Completes Part Three — On the Engines.
