Review Summary

What survived the funnel

Open this run to answer one question: is this real attacker-relevant behavior with real impact, or just normal contract plumbing?

Review Checklist
1. Read the findings table first. Ignore raw jobs until the result looks real.
2. Confirm attacker control, not just the existence of a sink.
3. Confirm money or privilege impact.
4. Keep it if the behavior is real. Kill it if this is normal proxy, admin, or upgrade plumbing.

[codex:780791] You are a security auditor. Audit this Solidity codebase for exploitable vulnerabilities.
[codex:780791] Focus on: reentrancy, access control, upgradeability/proxy issues, signature validation, oracle manipulation,
[codex:780791] accounting/invariant breaks, external call patterns, unchecked return values, and dangerous delegatecall.
[codex:780791] 
[codex:780791] Scope rules:
[codex:780791] - You MUST fully read `AUDIT_BUNDLE.txt` before concluding. It contains the complete contents of all first-party `contracts/**/*.sol` files.
[codex:780791] - Treat `lib/` and `@openzeppelin/` as third-party dependencies; skip them unless there is a concrete misuse angle in first-party code.
[codex:780791] 
[codex:780791] Output MUST be valid JSON matching the provided schema.
[codex:780791] - If you find nothing meaningful: set no_findings=true and findings=[].
[codex:780791] - Otherwise: set no_findings=false and include findings with severity/category/title and file/line locations when possible.
[codex:780791] 
[codex:780791] Output constraints (IMPORTANT):
[codex:780791] - severity MUST be exactly one of: info, low, medium, high, critical (lowercase).
[codex:780791] - category MUST be exactly one of: access_control, reentrancy, math, oracle, upgradeability, auth, other.
