# MEOK OS — Keyholder AI Operating World

> A signed, keyholder AI-OS you can carry into any host. Not a chatbot widget — a portable,
> governed, offline-verifiable agent (dual-brain, care-floored) that turns a website/SaaS/OS into
> an AI OS. Rides MCP + A2A + Letta .af + AGNTCY-OASF; adds keyholder, OFFLINE-verifiable Ed25519
> identity + embedded governance (care-floor, hard-stops) — verify, don't trust.

## Agent interfaces (for agents/hosts)
- [MEOK Hatch](https://os.meok.ai/api/hatch): hatch a keyholder AI as a signed, portable mini-OS — A2A card + MCP + Letta .af + dual-brain (offline/online) + bootable 3D-OS body + governance. `?format=af` (Letta), `?format=oasf` (AGNTCY + keyholder-governance extension). (`/api/sap` = legacy alias.)
- [A2A Agent Card](https://os.meok.ai/.well-known/agent-card.json): discovery/identity (signed).
- [MCP server](https://os.meok.ai/api/mcp): JSON-RPC — initialize · tools/list · tools/call (talk/govern/sign/verify).
- [On-device runner](https://os.meok.ai/runner/meok-sap-runner.mjs): run a SAP locally, offline-verify + offline-first brain (MIT).
- [Verify](https://os.meok.ai/api/verify): offline Ed25519 verification — check any MEOK signature yourself.
- [Provenance](https://os.meok.ai/api/provenance): sign a research claim + its source into an offline-verifiable record (`?claim=&source=&kind=`). The moat on top of any workbench (e.g. Claude Science): reproducible → independently verifiable. Provenance ≠ truth.

## Assurance (defence + civilian)
- [Signed System Card](https://os.meok.ai/systemcard.html): JSP 936 (defence) ↔ EU AI Act / ISO 42001 (civilian), verify + tamper-test.
- [Signed card registry](https://os.meok.ai/registry.html): shareable, searchable, each independently verifiable.
- [Signed session rundown](https://os.meok.ai/api/rundown): auditable manifest of the build.

## Core
- [MEOK OS](https://os.meok.ai/): the operating world (Keyholder dock, ~40 apps, live 3D globe, guided tour).
- [Governance lookup](https://os.meok.ai/api/govern): what governs an industry → frameworks + signed legacy bridges.

## Provider
CSOAI / MEOK — UK Companies House 16939677. Keyholder, governed, care-floor 0.95. Every governed action Ed25519-signed and offline-verifiable.

## Buyer surfaces (insurers, boards, regulators)
- [Insurers evidence pack](https://meok.ai/insurers): underwriting data feed licence (reg deadlines + penalty exposure) + live measured provisions + offline verification.
- [Illinois SB 315 audit readiness](https://meok.ai/illinois-audit-readiness): disclosure 1 Jan 2027, independent audit 1 Jan 2028 — measured-current-state record.
- [EU CRA Art 14 readiness](https://meok.ai/cra-art14): reporting obligation 11 Sep 2026, up to EUR15M / 2.5% turnover.
- [Board pack](https://meok.ai/board-pack): measured-current-state record for procurement and boards.
