This is a read-style POST: pass/fail is determined from lightweight threshold evaluation of the latest visible execution, error uses stored execution status, unevaluated means the latest visible execution could not be meaningfully threshold-evaluated, and missing means no visible execution exists. ## OpenAPI ````yaml /openapi/fleet-manager-openapi.yaml post /api/v1/burn-in/sites/{site_id}/test-executions/coverage/ openapi: 3.0.3 info: title: Fleet Manager API version: 1.0.0 description: API for the Nscale Fleet Manager servers: [] security: [] paths: /api/v1/burn-in/sites/{site_id}/test-executions/coverage/: post: tags: - Burn-in summary: Check burn-in test coverage description: >- Return coverage buckets for the requested devices and burn-in test slugs.
