Ouroboros Thesis v18.0 — Multi-track Substrate ExpansionConsolidated record for v17.1–v18.12 delta graft sessions under Doctrine v6. This deposit covers sixteen tracked community and frontier integration tracks performed between 2026-05-28 and the present session. Rather than minting individual DOIs per session, this single record anchors the combined scholarly provenance.v17.x tracks (community substrate integrations): the-four (v17.1), a11oy-code formal proofs (v17.1.1), GraphLambda + GNN governance head (v17.2), UDS air-gap drone operations (v17.3), standardgalactic mathematics and ontology (v17.4), standardgalactic engineering and code substrate (v17.5), Mila multimodal + RL (v17.6), seehiong production substrate (v17.7), peterjliu agent-tooling (v17.8), and ten-innovation founder scout synthesis (v17.9).v18.x tracks (frontier architecture and observability): Frontier architecture five-frontiers (v18.0), Quantum substrate (v18.1), FOSS + NVIDIA agent infrastructure (v18.2), mitmproxy + anvaka visualization (v18.3), JohnMwendwa community UI (v18.4), Splunk/Datadog observability (v18.5), Dynatrace/NewRelic (v18.6), BetterStack/Honeycomb (v18.7), Palantir data platform (v18.9), PaloAlto security substrate (v18.10), CrowdStrike endpoint (v18.11), Fortinet network (v18.12).All contributions are Doctrine v6 compliant: zero sorry, zero open axioms, ORCID-attributed, concept-DOI chain intact. The concept DOI 10.5281/zenodo.19944926 resolves to this record. Companion Lean 4 proofs in szl-holdings/lutar-lean. Runtime counterparts in szl-holdings/platform.
