Comment on: Safety policy for constraining meta-agent modifications

@0xbrainkid — the integration diagram is clean. Receipt stream → drift detector → approval gate is exactly the right architecture. Two concrete next steps: Receipt stream hook: The gateway already emits a DecisionLog event on every policy evaluation ([source](https://github.com/scopeblind/scopeblind-gateway/blob/main/src/gateway.ts)). Exposing that as a subscribable stream (EventEmitter or async iterator) is straightforward. I'll spec a onReceipt(callback) interface that gives you the signed receipt + metadata per evaluation. Fingerprint inputs already in the receipt: Each receipt includes tool_name, decision (allow/deny), tier, timestamp, and request_id. For drift detection you'd track distribution shifts across those fields per iteration window. The signature chain ensures the meta-agent can't retroactively alter the history. Your progressive enforcement → trust level mapping is spot on. That's how we think about it internally — shadow mode is the default precisely because new in...
