# Hub Core

Reusable FastAPI, SQLAlchemy, and MCP primitives for FOS hubs.

`hub-core` is being extracted from the standalone State Hub repository as part
of `CUST-WP-0025`. The initial package slice contains only the generic database
models and schemas that can move without importing dev-hub concepts such as
topics, workstreams, tasks, decisions, SBOM, or token accounting.

## First Slice

- SQLAlchemy base metadata and timestamp helpers.
- Domain and managed-repository registry primitives.
- Agent message inbox primitives.
- Progress-event and capability-request primitives with generic JSON context
  fields for hub-specific references.
- Third-party service catalog and snapshot primitives.
- Matching Pydantic schemas for those primitives.
- Generic DoI report and summary schemas used by the MCP DoI tools.
- Router factory functions for domains, repos, messages, policy lookup, and
  progress, capability, and TPSC catalog/snapshot/report endpoints.
- Canonical FOS §10 risk and alert event types with `/progress/risks` and
  `/progress/alerts` read views.
- Shared utility helpers for slugs, pagination, repo path resolution, and
  trailing-slash path normalization.
- Alembic templates plus an initial core-schema migration for hub adopters.
- FastMCP base-server wrapper for generic orientation, messaging, capability,
  repo, DoI, TPSC/GDPR, risk/alert, and progress tools.

Domain-specific MCP tools follow in each hub package.
