Request body
application/json
HMAC-signed Base64-encoded metadata blob. Format: <hmac>.<base64-encoded-json>. Inner JSON shape: DeviceFingerprintSignalsMetadataDto (fields: timestamp, signalsType, payload, sdkPlatform, sdkVersion, signalsVersion). Server verifies HMAC via the service-configured `hmac_key` and rejects expired/replayed signatures based on the per-tenant CaptureMetadataConfig timestamp threshold.
Frontend interview-event code categorizing these signals; resolved against the interview-event dictionary (must be a FRONTEND-sender code, e.g. "captureAttemptFinished").
