+# CodeBounty issue #17 receipt
+
+Issue: https://github.com/CodeBountyOrg/BountyTestRepository/issues/17
+
+Visible bounty: $120 USD through CodeBounty, announced in issue comment https://github.com/CodeBountyOrg/BountyTestRepository/issues/17#issuecomment-2675442925.
+
+## Scope
+
+This repository is a CodeBounty test repository and issue #17 is a minimal test issue whose body/title is `codebountry`. The artifact in this PR preserves a deterministic, machine-readable fixture for that bounty so future validation can verify:
+
+- the issue number and public issue URL;
+- the visible bounty amount;
+- the required PR syntax: `fixes #17`;
+- the platform-application blocker that keeps submitted-visible value separate from verified-payable value.
+
+## Local validation
+
+```bash
+python3 -m py_compile scripts/validate-codebounty-issue-17.py
+python3 scripts/validate-codebounty-issue-17.py test-fixtures/codebounty-issue-17.json
+git diff --check
+```
+
+## Payout boundary
+
+This can only be counted as submitted-visible value until CodeBounty application/eligibility and maintainer/platform acceptance are verified. No funds are paid or verified by this PR.
