ADR index

Architecture Decision Records document important design choices and their consequences.

• ADR 0001: Layered architecture
• ADR 0002: Variant C batch manifest
• ADR 0003: Edge resolver as single source of truth
• ADR 0004: Runtime ports and bootstrap
• ADR 0005: Production runtime connectors
• ADR 0006: Authority and canonical IR
• ADR 0007: Release-set and deployment-set
• ADR 0008: Airflow parse-safe provider
• ADR 0009: Artifact delivery and cache materializer
• ADR 0010: Binding-set and credential resolvers
• ADR 0011: Canonical fingerprints
• ADR 0012: Vault runtime authentication
• ADR 0013: Reproducible rerun and retention
• ADR 0014: Route attestation as production safe-sample trust
• ADR 0015: One compiler for classic, flow, and folder authoring
• ADR 0016: Content-pinned declarative recipes
• ADR 0017: Canonical workload selection algebra
• ADR 0018: Hermetic tests stay outside the production runtime
• ADR 0019: Bounded Airflow mapping projects the dpone backfill ledger
• ADR 0020: Airflow observability correlation composes immutable and observed identity
• ADR 0021: Signed catalog bundles and closed extension conformance
• ADR 0022: Durable target commit journal and fence (Proposed)
• ADR 0023: Confined authoring transactions use atomic exchange and durable recovery
• ADR 0024: Airflow executable init-fetch uses a strict v2 wire boundary
• ADR 0025: Quality-gate authority is explicit and process-local
• ADR 0026: Digest-first runtime image certification and fail-closed GHCR promotion
• ADR 0027: Runtime connections have one logical authority
• ADR 0028: Frozen release policy and irreversible publication boundary
• ADR 0029: Canonical pipeline identity and source reference
• ADR 0030: Self-service capability projection and Studio boundary
• ADR 0031: Domain-first self-service uses canonical discovery and selection

New ADRs should include status, context, decision, consequences, and links to related implementation or documentation.
