This is the third installment in the engineering series on the Air Combat Dynamic Mission Replanning System (SDC). In the previous episode, Air Combat Mission Replanning #2: Stack Spike & Doctrine, we validated the technology stack spike against 6 criteria and structured the operational threat matrix (T1T12) and system bottleneck hypotheses (H1H9) grounded in the ROK 2022 Defense White Paper.

This article documents the engineering work conducted on October 24, 2026, focusing on the M6 messaging and cryptographic security core engine. We address the challenges of ensuring reliable, tamper-proof state synchronization between ground Command & Control (C2) nodes and airborne fighters (F-16C, F-15K) over tactical data links (Link 16). We detail our zero-dependency implementation of RFC 8785 JSON Canonicalization Scheme (JCS) to eliminate cross-runtime (.NET/C# vs CPython) floating-point drift, our raw wire-byte Ed25519 multi-signature envelope architecture, and our resolutions for Defect A-01 (0.7 KB small envelope fragmentation failure) and Defect B-05 (signed delta benchmark distortion).

This is the second installment in the engineering series on the Air Combat Dynamic Mission Replanning System (SDC). In the previous episode, Air Combat Mission Replanning #1: Architecture & KLM Analysis, we established the multi-tier distributed architecture, overcame the CPython 14.5s latency barrier, optimized GPU memory to 0.80 GB, and numerically validated the F-16C fuel integration model via 4th-order Runge-Kutta (RK4).

This article documents the engineering facts from October 23, 2026, when we conducted Technology Stack Spike (a) to de-risk core feasibility before full distributed prototype implementation. We present the verification of 6 quantitative pass criteria, along with the formulation of Operational Threat Situations (T1~T12) and System Bottleneck Hypotheses (H1~H9) derived from official doctrine analysis.
