Summary

/claim #18

Adds a focused sponsor-data-room-access-guard module for the Scientific Bounty System. This covers the private-challenge handoff between sponsor data release and solver/reviewer workspaces: dataset access grants, NDA and prequalification readiness, least-privilege role checks, expiry and revocation SLAs, stale-token review, audit events, and sponsor remediation packets.

This is intentionally separate from existing intake, rubric readiness, scoring, arbitration, appeal, anti-collusion, payout eligibility, IP-redaction, evidence-freeze, clarification-freeze, and award-transparency slices.
