# Repository classification receiving contract v1.0

Repo Manager reads `.repo-classification.yaml` as repository authority and
validates it against version 1.0 of the Custodian's Repo Classification
Standard. It publishes the validated value in repository snapshots; downstream
topic or domain services consume that projection and do not replace the file.

The required scalar fields are `category` and `domain`. Optional list fields
are `secondary_domains`, `capability_tags`, `business_stake`, and
`business_mechanics`. Controlled values and the tag syntax are in the companion
machine-readable contract.

Invalid classifications fail observation with field-specific errors. Repo
Manager does not coerce unknown values, infer the primary domain from technical
tags, or write classification during observation. A canon vocabulary change
requires a new contract version and implementation update; the canon remains
the source of meaning.

Boundary with hub-core: Repo Manager owns file validation and the repository
projection. Hub-core may aggregate those projections into topics and fleet
navigation, but does not become classification authority.
