Summary

• Adds a dependency-free fixture for CodeBounty issue test issue creation from external sponsor #2 apr 15 #96's external-sponsor bounty metadata.
• Adds a validator that checks the issue number, public bounty amount, required Fixes #96 linkage, application-required status, and payout-boundary fields.
• Keeps verified_payable false until CodeBounty platform application/maintainer acceptance is verified.

Fixes #96

Validation

• python3 -m py_compile scripts/validate-codebounty-issue-96.py
• python3 scripts/validate-codebounty-issue-96.py test-fixtures/codebounty-issue-96-external-sponsor.json

Collision / eligibility check

• Re-fetched CodeBountyOrg/BountyTestRepository#96 immediately before push: issue was open, unlocked, unassigned, labeled 💰 Bounty Available, with 4 comments.
• Re-fetched repo metadata immediately before push: public and not archived.
• Checked open PRs for 96, fixes #96, and issue 96: 0 same-scope open PR collisions.
• Payout blocker remains: CodeBounty platform application/eligibility and maintainer acceptance are not verified from GitHub alone.
