Policy state is versioned before action is taken
What happened: rule interpretation drifted between teams. CTL made policy version and signer identity explicit before execution. Decision outcome: allow/block refers to a concrete policy snapshot.
Deterministic Trust
When trust is questioned, CTL shows the decision path instead of asking for belief.
What happened: approvals and denials were hard to justify under pressure. Human consequence: delayed incident handling and inconsistent risk calls. CTL makes policy inputs, signer evidence, and capability checks explicit so every allow/block outcome is replayable.
Artifact trust is checked before runtime trust
Human consequence addressed: fewer surprise binaries in production. CTL blocks execution when provenance or signature evidence is missing.
Capability access is a decision, not a default
Junior action: request capability through contract scope, not manual override. Architect rationale: no implicit privilege inheritance keeps trust boundaries stable across growth.
Decision replay replaces post-incident speculation
Operational outcome: reviewers can replay exactly why a request was allowed or blocked, including policy context and timing metadata.
How one trust decision is produced
Input validation
What happened: actor identity, request context, and contract scope are verified.
Policy match
CTL makes contradiction explicit by matching request to deterministic policy rules.
Artifact trust
Decision outcome: request is blocked if artifact evidence fails provenance/signature gates.
Audit emit
Operational outcome: allow/block event is logged for replay and compliance review.
What CTL will not do
- No black-box approvals.
Every critical trust decision must point to policy evidence, not opaque automation.
- No unrestricted local trust.
Local context does not bypass entitlement, signer, or capability gates.
- No arbitrary launcher execution.
Distribution and launch remain governed, signed, and reviewable.
Next Action
Use trust evidence before any runtime approval
Junior action: review trust model, then follow runtime contract checks. Architect rationale: replayable allow/block decisions keep governance reliable under scale and incident pressure.
