Integrate Mutation and Evidence Accountability into evidence console and FogStack manifests

[mdheller]

Purpose

Integrate SourceOS Mutation and Evidence Accountability into Prophet Platform evidence-console and FogStack manifest surfaces.

Canonical spec PR:

SourceOS-Linux/sourceos-spec#96

Required work

• Add evidence-console support for SourceOS receipt families: MutationReceipt, ExecutionContextReceipt, ServiceWorkReceipt, and EvidencePipelineReceipt.
• Extend FogStack/service manifests with declared write budgets, log/evidence budgets, sync budgets, temporary artifact budgets, and evidence-routing policy.
• Add policy gates that reject services with unbounded logging, opaque temporary artifacts, missing actor chains, or false compromise clearance from degraded sensors.
• Support evidence-quality display: complete, partial, degraded sensor, opaque symbolication, redacted, and insufficient-for-clearance.
• Surface delegated mutation chains across local/fog/cloud execution.

Acceptance criteria

• Evidence console can render at least one validated fixture from SourceOS spec PR Wire zone-aware Lampstand smoke into standard smoke path #96.
• FogStack manifest schema can declare mutation and evidence budgets.
• Policy gate rejects a service that claims clearance with blind/degraded sensors.
• Operator can see actor chain, object/path class, operation, policy, resource cost, causal parents, evidence gaps, and downstream effects.
