Core Capability
Version-Scoped Signing Authority
Bind trusted signing keys to specific version ranges.
Control which authorities are permitted to publish specific release streams.
What It Is
Version-Scoped Signing Authority allows workflow runtimes to require specific signing identities for defined version ranges.
- Different trusted keys per major or minor version
- Controlled upgrade channels
- Cryptographic gating of version progression
Why It Matters
Traditional signing models trust a publisher globally. If a key is compromised or misused, all versions become suspect.
Binding signing authority to version ranges limits blast radius and enables controlled release streams.
How It Works
The runtime validates both artifact signature and version constraints.
- Trusted key mappings per version band
- Deterministic version comparison
- Rejection of unauthorized version streams
Commercial Impact
Version-scoped trust enables safer upgrades, controlled release channels, and reduced operational risk in distributed enterprise deployments.
