Automated Multi-DRM Media Packaging Release Spec

Role: Staff Media Security & Release Engineer specializing in FairPlay, Widevine, PlayReady packaging, and automated CI/CD validation.

Context

• Media Catalog Service: {{media_catalog_service}}
• Supported DRM Technologies: {{drm_technologies_list}}
• Target Packaging Format: {{packaging_format}}
• Secrets Management Solution: {{secrets_manager_solution}}
• Max Blast Radius Percentage: {{blast_radius_limit_percentage}}
• Staging Validation Environment: {{staging_validation_environment}}

Task

Draft a formal technical deployment specification that integrates automated multi-DRM packaging validation into the release pipeline for {{media_catalog_service}}, verifying key rotation and player playback across {{drm_technologies_list}} before promoting releases to production.

Method

1. Define automated cryptographic key injection mechanisms utilizing {{secrets_manager_solution}} during packaging runs.
2. Detail CPIX/SPEKE protocol test fixtures to validate packaging into {{packaging_format}}.
3. Establish automated player client verification tests across each engine in {{drm_technologies_list}} inside {{staging_validation_environment}}.
4. Configure a phased canary rollout pattern capped at {{blast_radius_limit_percentage}} of active catalog cataloging traffic.
5. Specify real-time license acquisition telemetry metrics to detect unauthorized key generation or DRM handshake failures.
6. Formulate an automated rollback trigger when license issuance error rates exceed 0.05%.
7. Map audit logging requirements for key access and packaging manifest generation.

Constraints

• MUST NOT store raw DRM content encryption keys (CEKs) in CI runner environments or unencrypted build logs.
• MUST validate playback across all engines in {{drm_technologies_list}} before widening rollout beyond {{blast_radius_limit_percentage}}.
• Secret retrieval from {{secrets_manager_solution}} must use short-lived, rotated tokens.
• Staging validation must complete in {{staging_validation_environment}} within 10 minutes per build.

Output format

Provide a structured technical specification organized as follows:

1. Cryptographic Key Management & CI/CD Security Architecture (max 250 words)
2. Staging Validation Matrix (table with DRM System, Packaging Target, Test Device/CDM, Pass Criteria)
3. Progressive Rollout & Blast Radius Controls (ordered workflow, max 200 words)
4. Telemetry Alarm Thresholds & Rollback Plan (bulleted operational parameters)

Self-review

• Ensure every DRM system listed in {{drm_technologies_list}} has explicit test coverage in the matrix.
• Verify that secrets management strictly uses {{secrets_manager_solution}} with non-persistent keys.
• Confirm rollout controls never exceed {{blast_radius_limit_percentage}} during initial canary deployment.
