5. What this demonstrates against the challenge

outcome evidence above
EO-1 software capability library + HTTP service, stdlib only
EO-2 all domains / services 9 message types across LAND/AIR/MARITIME/SPACE/CYBER and C2/INTEL/FIRES/MEDICAL/LOGISTICS (§3)
EO-3 MTF-XML + NIEM/NCDF with documented interfaces §2 renders, docs/ICD.md
EO-4 modular, COIE, extensible COIE wire form (§2); catalogue-driven codecs; register()
EO-5 integration incl. sim / wargaming §4 picture update + CoT; seeded bearer model (§3)
DO-1 DDIL §3 compaction, fragmentation, precedence, store-and-forward, delivery vs J/S
DO-2 UX / multilingual / automation / decision aids §1 assured drafting (EN/FR lexicons)
DO-3 service-management API §4 Prometheus metrics, HEC + ServiceNow-shaped sinks
DO-4 AI/ML readiness confidence / abstain / evidence contract in §1; audit chain in §4
