- Interface version and parameter set
- Clock/reset domains and integration constraints
- Companion memory, PHY and software requirements
- Verification collateral and acceptance criteria

The selected release must confirm:

- Node/library binding
- Clock/reset limits
- Physical and protocol dependencies
- Artifact hashes
- Acceptance criteria

Unpublished values are not inferred from family names or architecture targets.

## Know the release.
Know what it establishes.

Canonical technology and its architecture/integration role are recorded. The offered delivery is confirmed against the exact release before licensing.

This is a controlled-portfolio summary, not a fresh execution of the chip qualification flow.
