The Tezos X Developer Toolbox, v19.
Fifty-three layers of working engineering knowledge for the sovereign stack — from your first RPC call to governed AI agents, compliance evidence, and signed publication. Every layer is plain files: read them, run them, or hand them to an agent (an llms.txt manifest ships at the root).
Foundations · 00–10
The chain fundamentals: how to read it, connect to it, sign against it, index it, and batch on it — plus the runnable template gallery and canonical reference set.
Domains · 11–22
The vertical stacks: InterbankOS banking rails, agentic AI, adapters and patterns, Bitcoin interop, DeFi, account abstraction, digital identity & compliance, edge gating, and agent authority.
Platform & collaboration · 23–35
Edge AI backends, signed multisignature publication, developer experience, encrypted group chat and collaboration infrastructure, MCP-governed connectors, observability evidence, production hardening, and the sovereign platform kernel.
Operations & assurance · 36–52
The operational spine: dev portal, reference cards, blueprints, the runtime policy engine, UI system kit, release integrity, flow simulation, deployment runbooks, contract schemas, the toolbox doctor, threat-model compilation, compliance evidence control plane, session policy, performance budgets, and the launch console.
README. For agents, llms.txt and 00-START-HERE/AGENT_INSTRUCTIONS.md define the entry contract; for humans, start with the Quick Start or the package manifest. Version and upgrade lineage: v19 upgrade report.
