ChromaMatter Linux x86_64 technical alpha source status

The binary may be distributed only when DISTRIBUTION_APPROVAL.json says
"approved" for the exact application inventory, component map, SPDX SBOM,
corresponding-source stage, archive audit, and explicit owner decision.

A generated candidate manifest or a successful application build alone is not
distribution approval. Missing source, license, relinking, archive, or owner
evidence keeps the gate blocked.
