Anika Settlement Stack — Build Report (2026-09-21)

Real, working software. Nothing here is mocked: every component has code + passing tests as evidence, labeled per Leonard's verification ladder (DESIGNED → CONFIGURED → VERIFIED → PRODUCTION). Technology information only — no institutional, banking, sovereign, or partnership claims anywhere.

Live status dashboard: https://brewpage.app/public/ndrtnLhOch (expires 2026-10-21; state regenerated from live sources; "How to verify" on the page reproduces every number)

Component states

Component	Dir	State	Evidence
Vault engine (valuations, encumbrance ledger, 40% LTV)	`vault-engine/`	VERIFIED	47/47 tests green; $500T/$200T stress test; double-pledge guard; append-only integrity. BigInt µUSD, zero precision loss. Crypto feed defaults to null (throws, never invents a price).
SettlementVault + DutchAuctionLiquidator contracts	`contracts/`	VERIFIED	Compiles solc 0.8.30 / Cancun / OZ v5; 25/25 Hardhat tests incl. end-to-end vault→breach→auction→settlement. Artifacts exported (vault 8,348 B, liquidator 7,050 B).
Chain mirror (Anika Chain event log + Firestore adapter)	`chain-mirror/`	VERIFIED	SettlementLog deployed at `0xDAA7B3e3c68fbfACD9d319Df0AB610D94814b9ad` (Anika Chain 20260921); live round-trip proven; Firestore shapes → chain events; Base txHash proof flow confirmed.
Disbursement (50/30/20 USDC split engine)	`disbursement/`	VERIFIED	13/13 tests; dust policy deterministic; dry-run default; unsigned signing queue only. Base USDC `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913` confirmed live. EXECUTED=0.
Express backend (`server/valuation.js`, `/api` routes)	`express-app/`	VERIFIED	37/37 tests; scaffold shape built; KYC simulate / lending ledger-only / off-ramp illustrative / Stripe demo — all labeled in code and responses.
Wallet-signed deploy console	`deploy-console/`	VERIFIED	57/57 checks; bytecode sha256-verified at build; smart-wallet guard; receipt.status + getCode + read-back before any success reported.
Dashboard (status page + Garcia Sounds drop-in)	`dashboard/`	VERIFIED	11/11 `verify.sh` checks; every number regenerated from live sources.

What is PRODUCTION vs what awaits Leonard

Nothing is PRODUCTION. No contract is deployed to any public network, no money moves, no lending occurs. Specifically awaiting Leonard's own signature/action:

SettlementVault + DutchAuctionLiquidator deployment on Base → use deploy-console/dist/index.html (six-step wallet-signed flow; price oracle address is honestly TBD — the vault cannot deploy until it is entered).
Express backend deployment (needs his JWT_SECRET, domain, Stripe keys, real KYC vendor).
Garcia Sounds integration: add dashboard/drop-in/js/settlement.js to his app; paste firestore.rules (already his file) — no changes needed to his app otherwise.
Credential purge/rotation per his own architecture doc §9.1 (his action).

Open flags (need Leonard's call)

LTV conflict: the scaffold README specifies per-class max LTV (crypto 65%, app 45%, music 40%, patent 25%); the standing platform rule is 40% max. Both are implemented as documented — crypto 65% / app 45% exceed 40%. Neither was silently changed. Flagged in code (LTV CONFLICT), ltvConflictReport(), and the dashboard.
On-chain events are fixtures only (SAMPLE round-trip + demo uid) — no real Garcia Sounds user data is mirrored on-chain yet.
EtherNode "ETH generator" pages (his uploads) must not be published as-is — reputational risk; quarantined.

Integration notes

Anika Chain was down at build start; all 4 nodes restarted, Clique sealing resumed.
Gotcha: Anika genesis has no Shanghai/Cancun (PUSH0 reverts) — contracts targeting it must compile evmVersion: paris (opposite of the Base/Cancun rule).
Disbursement ledger.jsonl grows by design (append-only); test runs add DRY-RUN entries — count is not a bug; EXECUTED stays 0 until Leonard signs a real payout.
