+# SourceOS/SociOS Typed Contracts Starter Kit (v2)
+
+This revision closes the biggest implementability gaps from v1:
+- Adds Agreement + Glossary + Connector/Asset + SchemaDefinition + Provenance + Collaboration objects
+- Upgrades policy conditions to a typed `PolicyCondition` with a declared language (jsonlogic/cel/rego/cedar)
+- Adds a minimal Hydra/JSON-LD semantic overlay (semantic/context.jsonld + semantic/hydra.jsonld)
+- Upgrades Dataset to reference Asset + Schema + Agreements explicitly (no implicit physical fields)
+
+## Topology position
+
+- **Role:** canonical typed-contract, JSON-LD, and shared vocabulary lane for SourceOS / AgentOS.
+- **Connects to:**
+  - `SociOS-Linux/agentos-spine` — Linux-side integration/workspace spine that consumes and routes these contracts
+  - `SociOS-Linux/workstation-contracts` — workstation/CI specialization and conformance lane
+  - `SociOS-Linux/SourceOS` — immutable substrate that should consume typed policy and artifact semantics
+  - `SociOS-Linux/socios` — opt-in automation layer that should reference, not redefine, these contracts
+  - `SocioProphet/sociosphere` — platform workspace controller that may mirror or reuse shared contract vocabulary
+  - `SocioProphet/socioprophet` and `SociOS-Linux/socioslinux-web` — public documentation surfaces that explain these contracts downstream
+- **Not this repo:**
+  - workspace controller
+  - image builder
+  - public docs site
+  - opt-in automation plane
+- **Semantic direction:** this repo should become the canonical home for shared repo ontology, JSON-LD contexts, and vocabulary definitions that other repos publish by reference.
+
+## Why this matters
+If a contract bundle does not cover agreements, glossary, and asset connectors, the metadata plane cannot unify governance and meaning end-to-end.
+We now have a closed set of object families that directly correspond to the Open Metadata Types taxonomy areas:
+- Area 1: Physical assets -> Connector, PhysicalAsset
+- Area 2: Glossary -> GlossaryTerm
+- Area 3: Governance -> Policy/Decision/Token/Obligations
+- Area 4: Collaboration -> Comment/Rating/Community
+- Area 5: Models/Schemas -> SchemaDefinition, EntityField, ValidValues
+- Area 6: Agreements -> Agreement, Party
+
+## Minimal implementation path (practical)
+1) Schema validation: AJV (Node) or jsonschema (Python).
+2) Codegen: TypeScript types (quicktype) or Python models (datamodel-code-generator for Pydantic).
+3) API service: OpenAPI -> FastAPI scaffold.
+4) Event spine: AsyncAPI -> Kafka topics with schema validation at the producer/consumer boundaries.
+
+## Compatibility discipline
+- IDs are stable URNs; specVersion is semver.
+- Additive changes should remain backward compatible; breaking changes increment major.
 # SourceOS/SociOS Typed Contracts
 
 **SourceOS/SociOS Typed Contracts** is the canonical, machine-readable specification for the SourceOS metadata governance platform and the SociOS agent plane. It defines the full set of JSON Schemas, an OpenAPI REST surface, an AsyncAPI event spine, and a JSON-LD / Hydra semantic overlay that together make up the "contract layer" every implementation component must satisfy.
