Expose runtime contracts for rescued agent configuration workbench

[mdheller]

Context

SocioSphere capture: SocioProphet/sociosphere#333
UI owner: SocioProphet/socioprophet#323

The rescued platform work describes an Agent Configuration / Agentic Workbench surface with multimodal knowledge attachment, schema/type configuration, skills, evaluation, deployment scale, health metrics, and evolution triggers. This issue owns the AgentPlane runtime contract required by that UI.

Required runtime capabilities

• list agent profiles and deployment state
• read/write agent configuration drafts
• attach knowledge-base references by capability-bound URI
• expose skills/evaluation metadata for UI display
• submit evaluation runs and return status
• expose agent health/telemetry summary
• expose replay/evolution candidate events
• require creator approval for evolution promotion

Contract shape

Define fixtureable methods for the Vue adapter layer:

• agentplane.agents.list
• agentplane.agents.get
• agentplane.config.draft.create
• agentplane.config.validate
• agentplane.knowledge.attach
• agentplane.eval.submit
• agentplane.eval.status
• agentplane.telemetry.summary
• agentplane.evolution.candidates
• agentplane.evolution.approve

Acceptance criteria

• Add API/contract documentation for the above methods.
• Add JSON fixtures usable by the SocioProphet Vue adapter test mode.
• Clarify which methods are live, fixture-only, or future.
• Link trust/capability requirements to mcp-a2a-zero-trust.
• Include negative fixtures for unauthorized attachment/evolution approval.
