Track cross-repo event-native orchestration interop proof

[mdheller]

Context

The sovereign device orchestration program now has a CI-gated fixture proof in prophet-platform, plus Guardrail Fabric policy generation, SourceOS queue/replay, AgentPlane admission PR #130, and Sherlock event-capability search.

This issue tracks the cross-repo proof path documented in:

specs/orchestration/CROSS_REPO_INTEROP.md

Goal

Demonstrate the complete event-native loop across repos:

Prophet contract -> Guardrail policy annotation -> SourceOS queue/replay -> AgentPlane admission -> Sherlock search

Acceptance criteria

• Prophet Platform world_class_event_loop_demo.py emits demo-report.json with status == pass.
• Guardrail Fabric annotates unannotated event-capability records with generated policy outcomes.
• SourceOS queue shows at least one pending, one waiting-approval, and one blocked record.
• SourceOS replay emits a non-mutating replay artifact.
• AgentPlane admission artifact has zero invalid records.
• Sherlock search returns evidence-backed hits preserving event id, capability id, reaction id, policy outcome, idempotency key, policy epoch, and receipt refs.
• No live device actuation, provider call, credential collection, or camera media retention occurs.

Non-goals

• No live home/device actuation.
• No proprietary credentials.
• No camera-media retention.
• No cloud dependency.

Current blockers

• AgentPlane PR Gate zone-router publication staging on semantic-bridge validation #130 remains open; direct merge was rejected by branch protection despite visible lint success.
