# feast - Doramagic AI Context Pack > Purpose: pre-work context for the user's host AI. This pack does not prove that the project has been installed, run, or validated. ## Project - canonical_name: `feast-dev/feast` - capability: The Open Source Feature Store for AI/ML - expected_user_outcome: The Open Source Feature Store for AI/ML ## Operating Boundaries - Do not claim that the project has been installed, run, called through an API, or used on local files unless separate evidence proves it. - Project facts must come from repo evidence, Claim Graph, or explicit source references. - When a capability is not verified, mark it as unverified instead of completing it as fact. - publish_status: `publishable` - blocking_gaps: none --- ## Doramagic Context Augmentation The following sections strengthen the repository context for a host AI. Human Manual data is a reading route, and pitfall notes become operating constraints. ## Human Manual Outline Usage rule: this is only a reading route and salience signal, not factual authority. Concrete claims must still return to repo evidence or Claim Graph. Host AI hard rules: - Do not treat page titles, section order, summaries, or importance values as factual project evidence. - When explaining the Human Manual outline, state that it is only a reading route or salience signal. - Capability, installation, compatibility, runtime state, and risk claims must cite repo evidence, source paths, or Claim Graph. - **Feast Overview, Architecture, and Core Concepts**: importance `high` - source_paths: README.md, sdk/python/feast/feature_store.py, sdk/python/feast/feature_view.py, sdk/python/feast/batch_feature_view.py, sdk/python/feast/entity.py - **Data Stores, Materialization, and Feature Retrieval**: importance `high` - source_paths: sdk/python/feast/infra/online_stores/online_store.py, sdk/python/feast/infra/online_stores/redis.py, sdk/python/feast/infra/online_stores/remote.py, sdk/python/feast/infra/online_stores/hybrid_online_store/hybrid_online_store.py, sdk/python/feast/infra/online_stores/milvus_online_store/milvus.py - **Feature Servers, Compute Engines, and Transformation Pipeline**: importance `high` - source_paths: sdk/python/feast/feature_server.py, sdk/python/feast/offline_server.py, sdk/python/feast/registry_server.py, sdk/python/feast/transformation_server.py, sdk/python/feast/infra/mcp_servers/mcp_server.py - **Deployment, Kubernetes Operator, Web UI, and Operations**: importance `high` - source_paths: infra/feast-operator/api/v1/featurestore_types.go, infra/feast-operator/internal/controller/featurestore_controller.go, infra/feast-operator/config/crd/bases/feast.dev_featurestores.yaml, infra/charts/feast/values.yaml, infra/charts/feast-feature-server/values.yaml ## Repo Inspection Evidence - repo_clone_verified: true - repo_inspection_verified: true - repo_commit: `f0c5be8a66f3d3f2c7a6e560b926b25d53f3042f` - inspected_files: `README.md`, `pyproject.toml`, `docs/README.md`, `docs/SUMMARY.md`, `docs/adr/ADR-0001-feature-services.md`, `docs/adr/ADR-0002-component-refactor.md`, `docs/adr/ADR-0003-on-demand-transformations.md`, `docs/adr/ADR-0004-entity-join-key-mapping.md`, `docs/adr/ADR-0005-stream-transformations.md`, `docs/adr/ADR-0006-kubernetes-operator.md`, `docs/adr/ADR-0007-unified-feature-transformations.md`, `docs/adr/ADR-0008-feature-view-versioning.md`, `docs/adr/ADR-0009-contribution-extensibility.md`, `docs/adr/ADR-0010-vector-database-integration.md`, `docs/adr/ADR-0011-data-quality-monitoring.md`, `docs/adr/ADR-0012-label-view.md`, `docs/adr/ADR-TEMPLATE.md`, `docs/adr/README.md`, `docs/adr/rfc-feature-view-versioning.md`, `docs/blog/README.md` Host AI hard rules: - Without repo_clone_verified=true, do not claim that the source code has been read. - Without repo_inspection_verified=true, do not write README, docs, or package-file conclusions as facts. - Without quick_start_verified=true, do not claim that the Quick Start path has run successfully. ## Doramagic Pitfall Constraints These rules come from Doramagic discovery, validation, or compilation findings. The host AI must treat them as operating constraints, not background notes. ### Constraint 1: Installation risk requires verification - Trigger: Project evidence flags a installation risk. Review the linked source before relying on this workflow. - Host AI rule: Reproduce the official install and quickstart path in an isolated environment. - Why it matters: May increase setup, validation, or first-run risk for the user. - Evidence: community_evidence:github | https://github.com/feast-dev/feast/issues/6488 - Hard boundary: Do not present this pitfall as solved, verified, or ignorable unless later evidence explicitly closes it. ### Constraint 2: Capability evidence risk requires verification - Trigger: README/documentation is current enough for a first validation pass. - Host AI rule: Reproduce the official install and quickstart path in an isolated environment. - Why it matters: May increase setup, validation, or first-run risk for the user. - Evidence: capability.assumptions | https://github.com/feast-dev/feast - Hard boundary: Do not present this pitfall as solved, verified, or ignorable unless later evidence explicitly closes it. ### Constraint 3: Maintenance risk requires verification - Trigger: Project evidence flags a maintenance risk. Review the linked source before relying on this workflow. - Host AI rule: Reproduce the official install and quickstart path in an isolated environment. - Why it matters: May increase setup, validation, or first-run risk for the user. - Evidence: community_evidence:github | https://github.com/feast-dev/feast/issues/6539 - Hard boundary: Do not present this pitfall as solved, verified, or ignorable unless later evidence explicitly closes it. ### Constraint 4: Maintenance risk requires verification - Trigger: Project evidence flags a maintenance risk. Review the linked source before relying on this workflow. - Host AI rule: Reproduce the official install and quickstart path in an isolated environment. - Why it matters: May increase setup, validation, or first-run risk for the user. - Evidence: evidence.maintainer_signals | https://github.com/feast-dev/feast - Hard boundary: Do not present this pitfall as solved, verified, or ignorable unless later evidence explicitly closes it. ### Constraint 5: Security or permission risk requires verification - Trigger: no_demo - Host AI rule: Reproduce the official install and quickstart path in an isolated environment. - Why it matters: May increase setup, validation, or first-run risk for the user. - Evidence: downstream_validation.risk_items | https://github.com/feast-dev/feast - Hard boundary: Do not present this pitfall as solved, verified, or ignorable unless later evidence explicitly closes it. ### Constraint 6: Security or permission risk requires verification - Trigger: no_demo - Host AI rule: Reproduce the official install and quickstart path in an isolated environment. - Why it matters: May increase setup, validation, or first-run risk for the user. - Evidence: risks.scoring_risks | https://github.com/feast-dev/feast - Hard boundary: Do not present this pitfall as solved, verified, or ignorable unless later evidence explicitly closes it. ### Constraint 7: Maintenance risk requires verification - Trigger: issue_or_pr_quality=unknown。 - Host AI rule: Reproduce the official install and quickstart path in an isolated environment. - Why it matters: May increase setup, validation, or first-run risk for the user. - Evidence: evidence.maintainer_signals | https://github.com/feast-dev/feast - Hard boundary: Do not present this pitfall as solved, verified, or ignorable unless later evidence explicitly closes it. ### Constraint 8: Maintenance risk requires verification - Trigger: release_recency=unknown。 - Host AI rule: Reproduce the official install and quickstart path in an isolated environment. - Why it matters: May increase setup, validation, or first-run risk for the user. - Evidence: evidence.maintainer_signals | https://github.com/feast-dev/feast - Hard boundary: Do not present this pitfall as solved, verified, or ignorable unless later evidence explicitly closes it.
