# EnfinitOS

> Governance / operating-layer infrastructure for DOOH and spatial-media operators. SDKs, OpenAPI reference, and the open-source auditor.

## Docs

- [Authentication](https://docs.enfinitos.com/authentication.md): How EnfinitOS authenticates SDK and HTTP API calls — bearer tokens, scopes, rotation, and the sandbox vs. production split.
- [GDPR](https://docs.enfinitos.com/compliance/gdpr.md): EnfinitOS supports Article 15 (access) and Article 17 (erasure) at the platform layer — exposed via dedicated DSAR endpoints.
- [Proof-pack format](https://docs.enfinitos.com/compliance/proof-pack-format.md): Canonical JSON shape, signing scheme, and chain semantics for the proof packs EnfinitOS issues.
- [Regulatory coverage](https://docs.enfinitos.com/compliance/regulatory-coverage.md): What EnfinitOS does — and explicitly does not — claim to cover from a regulatory perspective.
- [Verification keys](https://docs.enfinitos.com/compliance/verification-keys.md): How EnfinitOS publishes, rotates, and revokes verification keys. The public keys themselves and the rotation schedule.
- [Architecture](https://docs.enfinitos.com/concepts/architecture.md): Six layers — Control, Runtime, Spatial, Proof, Metering, Settlement — designed as one operating model rather than stitched together later.
- [Metering](https://docs.enfinitos.com/concepts/metering.md): How delivery events are projected into the metered units that contracts are denominated in.
- [Proof chain](https://docs.enfinitos.com/concepts/proof-chain.md): How EnfinitOS signs and hash-chains every delivery, activity, and operating action — and how the open-source auditor walks the chain offline.
- [Rights as a bounded context](https://docs.enfinitos.com/concepts/rights-as-bounded-context.md): Why rights deserve their own bounded context — and the lifecycle: basis → right → offer → counter → challenge → withdrawal / expiry / suspension / revocation.
- [Settlement](https://docs.enfinitos.com/concepts/settlement.md): Verified activity in, finance out — the disciplined path from metered units to invoices and reconciliations.
- [Substrate model](https://docs.enfinitos.com/concepts/substrate-model.md): Why 'substrate' rather than 'channel' — and the 23 substrates first-class in the EnfinitOS type system.
- [Introduction](https://docs.enfinitos.com/introduction.md): EnfinitOS is the governance and operating-layer infrastructure that DOOH and spatial-media operators run for runtime, proof, metering, and settlement discipline.
- [Quickstart](https://docs.enfinitos.com/quickstart.md): Send your first signed event into EnfinitOS and verify the resulting proof pack with the open-source auditor.
- [Sandbox API reference](https://docs.enfinitos.com/sandbox/api-reference.md): Public HTTP endpoints the EnfinitOS sandbox exposes — provisioning, rights bounded context, delivery, proof packs, constraint demos, audit inspector.
- [Sandbox architecture](https://docs.enfinitos.com/sandbox/architecture.md): How the EnfinitOS sandbox is layered — sandbox-core foundational library, edge-runtime HTTP API, in-browser auditor, and the upgrade path to a persistent backend.
- [Sandbox CLI](https://docs.enfinitos.com/sandbox/cli.md): Use the EnfinitOS CLI to drive the sandbox from your terminal — provision, run demos, fetch packs, verify offline.
- [Sandbox overview](https://docs.enfinitos.com/sandbox/overview.md): The hosted EnfinitOS sandbox — real cryptographic proof packs, real rights bounded context, real audit roundtrip. Available now — request access at enfinitos.com/apply.
- [SDK integration](https://docs.enfinitos.com/sandbox/sdk-integration.md): How the auditor SDK maps onto the sandbox HTTP API — code snippets for @enfinitos/sdk-auditor and @enfinitos/cli pointed at the sandbox. Other SDKs ship at the April 2027 production launch.
- [Auditor SDK](https://docs.enfinitos.com/sdks/auditor.md): Cryptographic verifier — Ed25519 signatures, SHA-256 hash chain, canonical-JSON re-projection. Open source under MIT.
- [Brand SDK](https://docs.enfinitos.com/sdks/brand.md): Read-only REST clients in TypeScript, Python, Go, Java, and Ruby — for brands and agencies to verify their own delivery.
- [EnfinitOS CLI](https://docs.enfinitos.com/sdks/cli.md): Operator-facing terminal — rights, offers, challenges, proof packs, consent, drills, audit export, pilots.
- [Operator Web SDK](https://docs.enfinitos.com/sdks/operator-web.md): React component library — embed the EnfinitOS operator surfaces in your own admin UI.
- [SDK catalog](https://docs.enfinitos.com/sdks/overview.md): 28 SDKs across every substrate the EnfinitOS platform governs. TypeScript, Python, Go, Java, Ruby, Rust, Swift, Kotlin, and more.
- [Render SDKs (per substrate)](https://docs.enfinitos.com/sdks/render-substrate-sdks.md): Substrate-specific render SDKs — DOOH, streaming, CTV, mobile, AR, gaming, automotive, smart home, wearables, audio, messaging.
- [Renderer Core](https://docs.enfinitos.com/sdks/renderer-core.md): The substrate-agnostic foundation every render SDK composes. Composition, not inheritance.
- [Robotics & Drone](https://docs.enfinitos.com/sdks/robotics-and-drone.md): Robotics SDK for autonomous fleets; Drone SDK extends it with airspace, Remote ID, NOTAM, and BVLOS waivers.
- [Transit & broadcast](https://docs.enfinitos.com/sdks/transit-and-broadcast.md): Adapter-mostly SDKs: satellite ground segments, in-flight entertainment, maritime IPTV + VTS.
