Cascade order: env row → CASCADE removes api_key / alert / deployment / template_snapshot / env_config_snapshot / annotation_queue; SET NULL preserves alert_history (denormalized name + epoch kept intact). Fly app destroy is attempted after the DB delete commits — on failure the env row is already gone and the response surfaces 500 `env_fly_provisioning_failed` for operator intervention. ## OpenAPI ````yaml /openapi.yaml delete /v1/environments/{id} openapi: 3.0.3 info: contact: email: hello@agentmark.co url: https://docs.agentmark.co description: >- The AgentMark Gateway API lets you ingest traces, create scores, and retrieve prompt templates programmatically. Most developers should use the [AgentMark SDK](/introduction/overview) for integration. The REST API is for cases where you need direct HTTP access or are building a custom integration. Versioning: every endpoint is prefixed with `/v1/`. Breaking changes ship under a new version prefix (`/v2/`, etc.) with a 90-day-minimum deprecation window — see [API versioning & stability](/api-reference/versioning) for the full policy on what constitutes a breaking vs. additive change. title: AgentMark Gateway API version: '1.0' servers: - description: Production (AgentMark Cloud) url: https://api.agentmark.co - description: Local dev server (`npx @agentmark-ai/cli dev`) url: http://localhost:9418 security: - AppId: [] BearerAuth: [] tags: - description: Ingest, query, and export OpenTelemetry trace data. name: Traces - description: >- Coding-agent session ingest (outerlayer sync) and content-addressed session images. name: Agents - description: Query individual spans across traces. name: Spans - description: Create, retrieve, list, and delete score records for spans and traces. name: Scoring - description: Structured-filter search across observability resources. name: Search - description: Retrieve the effective synced project configuration. name: Config - description: List and retrieve datasets. name: Datasets - description: Query server feature availability. name: Capabilities - description: Per-model LLM pricing data.
