name: Linera Standards Conformance
description: >-
  Cross-cutting standards posture for the Linera developer surface. Linera does
  not expose a REST/OpenAPI HTTP API; the node service exposes a GraphQL API
  over which frontends read and mutate microchain state. Entries are derived
  from the developer manual and published client crates; absence of a standard
  is honest data, not a gap to hide.
conformance:
  - id: graphql
    conforms: true
    evidence: >-
      The Linera node service exposes a GraphQL API (queries, mutations, and
      subscriptions) consumed by web frontends; a first-party
      linera-service-graphql-client crate and @linera/client web client target it.
  - id: graphql-subscriptions
    conforms: true
    evidence: Release notes document GraphQL subscription handling over watch channels.
  - id: oauth2
    conforms: false
    evidence: >-
      No OAuth2 flow; access to chain state is authorized by cryptographic
      wallet signatures rather than bearer tokens.
  - id: oidc
    conforms: false
    evidence: No OpenID Connect surface.
  - id: rfc9457
    conforms: false
    evidence: No HTTP problem+json error surface; errors are returned in the GraphQL error envelope.
  - id: json-api
    conforms: false
    evidence: Not a JSON:API REST surface.
  - id: fapi
    conforms: false
    evidence: Not a financial-grade OAuth API.
