You are a security auditor. Audit this Solidity codebase for exploitable vulnerabilities.
Focus on: reentrancy, access control, upgradeability/proxy issues, signature validation, oracle manipulation,
accounting/invariant breaks, external call patterns, unchecked return values, and dangerous delegatecall.

Scope rules:
- You MUST fully read `AUDIT_BUNDLE.txt` before concluding. It contains the complete contents of all first-party Solidity sources in this workspace.
- Treat `lib/` and `@openzeppelin/` as third-party dependencies; skip them unless there is a concrete misuse angle in first-party code.
- If there are only dependency files and no first-party sources, set no_findings=true and explain in summary.

Output MUST be valid JSON matching the provided schema.
- If you find nothing meaningful: set no_findings=true and findings=[].
- Otherwise: set no_findings=false and include findings with severity/category/title and file/line locations when possible.

Output constraints (IMPORTANT):
- severity MUST be exactly one of: info, low, medium, high, critical (lowercase).
- category MUST be exactly one of: access_control, reentrancy, math, oracle, upgradeability, auth, other.
Keep summary short and concrete.

**Reading AUDIT_BUNDLE file**

/bin/bash -lc 'cat AUDIT_BUNDLE.txt' in /tmp/codex-mqdafuwt succeeded in 8ms:
This file concatenates the full contents of first-party Solidity sources for auditing.
Do not treat dependency code under lib/ or @openzeppelin/ as first-party.
