Require distinct autonomy stage report records #465

🤖 Generated by the Agentic Engineer

Problem

An otherwise complete offline proof can reuse one report record for every evidence stage and still recommend a candidate. Unique report IDs do not establish distinct stage records.

Reproduced offline against freshly fetched 82d0313, with a valid control. No inspected guidance, surveyed package, remote publication or inference launch was executed.

Acceptance criteria

Require distinct stage record references as well as IDs; keep unique complete proofs valid; add actual assessor RED/GREEN cases. Size: S.

Part of #223.
