Fix & Proposed Solution

Closes #18

🛠️ Proposed Solution (by Aditya Waghamare)

Analysis

Issue #18 documents and retroactively settles the full-repository security audit delivered in PR #17. The core issue addressed was a governance gap in the no-quota rules regarding unprompted repository security audits, alongside verifying six critical defensive security fixes applied across the codebase.

Fix

Verified and approved the retroactive governance task settlement and defensive security hardening implemented in PR #17:

1. Escrow & Refund Ownership: Ensured refund validates recipient identity against escrow depositor records, preventing funds redirection. Added depositor ownership checks to escrow structures.
2. Settlement Evidence Integrity: Enforced canonical GitHub PR URL parsing and status verification for all settle transactions.
3. Scanner & CI Injection Hardening: Resolved unhandled unreadable file errors and shell invocation risks in scan-repo.mjs, escaped GitHub Actions annotation commands, and restricted security allowlists to exact-line matching.
