Reads only an exact capture member from the selected immutable bundle; never serves report HTML or arbitrary archive paths. Each member is at most 64 MiB. The complete canonical archive and member digest are verified, followed by fresh authorization, evidence identity and expiry checks. PNG and WebM may be previewed inline; ZIP is always an attachment. download=1 forces attachment. Supports one inclusive byte range after verification. A missing, expired, deleted or digest-mismatched selection returns 404; an invalid range returns 416. Video and traces are not redacted. Responses are private, no-store, nosniff and no-referrer. ## OpenAPI ````yaml /api-reference/openapi.json get /v1/projects/{projectId}/browser-runs/{runId}/artifacts/{artifactPath} openapi: 3.1.0 info: title: Firedrill Control API version: 1.0.0 description: >- The control plane for drills, drill runs, and the worlds they run in.
