A bundle is production-ready only when its targets are narrowly scoped, its deployment modes are correctly wired, the run-as identity is minimally privileged and correctly gated, variables are bound at deployment time only and never at runtime, authentication is wired through OAuth or environment variables rather than persisted tokens, the Git folder flow is segregated (admin production folders do not share branches with user folders), and every CI/CD gate is written to prevent accidental promotion to a higher environment.",

    "CRITICAL — a bundle must contain exactly one configuration file named `databricks.yml` in its root; multiple configuration files, renamed files, or config-in-target-subdirectories is a defect, not a style choice. Flag any bundle structure that violates this one-config rule.",
    "CRITICAL — deployment modes have distinct semantics that are not interchangeable: development mode prepends `[dev ${workspace.current_user.short_name}]` to resource names, marks pipelines `development: true`, and permits a `--cluster-id` CLI override; production mode enforces `development: false` for pipelines and forbids cluster overrides. Flag any production bundle configured in development mode or any development-mode bundle deployed without explicit acknowledgement. Development mode additionally PAUSES scheduled jobs automatically so a dev deployment does not fire on its own schedule — flag any expectation that a dev-target deployment will run on schedule, and flag any attempt to 'fix' a non-firing dev job by switching the target to production.",
    "CRITICAL — when the deploying identity differs from the `run_as` identity, only jobs and pipelines are supported as resources; Model Serving endpoints are explicitly unsupported and error. Flag any attempt to deploy a Model Serving endpoint or other non-job, non-pipeline resource under a non-self run-as identity as a hard incompatibility.",
    "HIGH — bundle variables are resolved at deployment time only; they are never available at runtime and cannot be looked up dynamically during a job or pipeline run. Flag any code or configuration that treats a variable as a runtime lookup or assumes a variable's value is accessible inside a Spark job.",
    "HIGH — OAuth U2M access tokens expire after one hour and refresh automatically; from Databricks CLI v1.0.0, tokens are stored in OS-native secure storage (macOS Keychain, Windows Credential Manager, Linux D-Bus). Where native storage is unavailable, a `DATABRICKS_AUTH_STORAGE=plaintext` fallback is required — flag this fallback as an insecure exception that must have explicit security approval.",
    "HIGH — the CLI authentication precedence is (1) bundle settings files, (2) environment variables, (3) `.databrickscfg` profiles; a bundle that hardcodes a workspace URL or personal access token in bundle configuration files is a credential exposure defect, not a supported pattern. Require environment variable or OAuth M2M binding.",
    "HIGH — Git folder flows must segregate admin (production-only, protected branches, automation-owned) from user (personal branches, user-owned). A Git configuration that mixes user and production branches in the same folder or permits direct pushes to production is a governance defect. Flag any flow that allows a user branch to become production.",
    "MEDIUM — the Terraform engine and the direct-deployment engine are separate paths for bundles; `bundle deployment migrate` moves between them, and behavior can differ (e.g., state management, rollback semantics). Any statement of \"the bundle deploys correctly\" must specify which engine and whether the engine choice is intentional or accidental.",
    "MEDIUM — bundle variables support a precedence order and optional lookups (alert, cluster_policy, cluster, etc.), but lookups are resolved at bundle validation time, not at runtime. Flag any variable whose lookup fails at validation as a configuration defect that must be fixed before deployment.",
    "LOW — Databricks CLI version 0.218.0 or above is required for bundles. Any deployment documentation or script still using an older CLI version is stale and must be updated; verify the deployment environment actually carries the required version before declaring readiness.",
    "LOW — `run_as` accepts `service_principal_name` or `user_name` and propagates from the bundle level into individual job and pipeline resources; a bundle relying on that propagation while also setting a per-resource `run_as` has two identities in play, so name which one each resource actually executes under rather than assuming the top-level value wins everywhere."
