Uzoma

AI agents that ship verifiable on-chain work.

Uzoma is an agent-native delivery workspace that turns smart-contract requests into structured specialist workflows, accepted artifacts, and verifiable Build Dossiers. The deployed on-chain component is Uzoma’s BuildDossierRegistry on Casper Testnet. The Milestone Escrow implementation shown in the demo is a reviewed delivery-artifact preview; it is not the deployed contract.

What is live now

• Live Lead Agent planning — new requests can receive structured plans, assurance assessments, specialist assignments, acceptance criteria, and review requirements through the server-side OpenAI integration.
• Structured delivery workflow — Axiom, Forge, Sentinel, and Verity model deterministic local specification, build, test, and review stages.
• Evidence-backed Build Dossiers — accepted delivery records include artifacts, reviews, deterministic hashes, and artifact roots.
• Casper Testnet proof — the deployed BuildDossierRegistry contains a confirmed anchor for the seeded demo-escrow dossier.

New jobs are planned live when configured and remain accepted local evidence records. They are structured for future explicit proof, but fresh user-controlled anchoring is not enabled in the submission build.

The problem

Generating code is easy. Accountable delivery is not.

• A code block is not a verifiable delivery record.
• Builders should not be the only reviewers of their own work.
• Requirements drift when planning, implementation, and review are disconnected.
• Accepted artifacts need stable hashes, receipts, and approval evidence.

The Uzoma solution

Uzoma makes each handoff explicit. A constrained server-side Lead Agent can use the OpenAI Responses API to turn a new delivery brief into validated acceptance criteria, specialist assignments, review requirements, and an explicit Casper anchoring policy. After a plan is created, the current build models specialist execution through deterministic local orchestration. This produces bounded artifacts, test evidence, independent-review records, and a portable Build Dossier.

The seeded workflow produces:

• a requirements and acceptance-criteria specification;
• a reviewed Milestone Escrow implementation preview;
• a test report covering success, failure, and edge cases;
• an independent acceptance review;
• a deterministic dossier hash and four-artifact root;
• a confirmed Casper Testnet proof for the accepted demo dossier.

Multi-agent workflow

Request → Plan → Build → Test → Review → Dossier
Axiom Forge Sentinel Verity
Define Build Test Verify

• Axiom defines requirements, workflow states, roles, invariants, acceptance criteria, and implementation boundaries.
• Forge builds contract artifacts against the approved specification.
• Sentinel validates success paths, failure paths, and edge cases.
• Verity independently checks the evidence before delivery is accepted.

These specialist profiles are local delivery services in the current build. MCP discovery remains planned integration; the app does not claim a live MCP connection.

Server-side Lead Agent

The live planner uses the official OpenAI Node SDK, the Responses API, and a strict Zod-backed structured output. The API key is read only inside the Node.js route; it is never returned to the browser, persisted in local workflow state, or written to logs.

Copy the variable names from .env.example into your own ignored local environment or hosting-provider secret store:

OPENAI_API_KEY=your_key_here
OPENAI_MODEL=gpt-5.4-mini

Model availability depends on the API project. Use a model available to your project that supports Uzoma’s structured planning workflow.

Both values are required. If OPENAI_MODEL is missing, the server returns a clear configuration error rather than selecting a hardcoded model. OpenAI API usage can incur model charges, so configure account limits appropriate to the demo. Never commit the key or expose it through a NEXT_PUBLIC_ variable.

The Lead Agent model is configured server-side through OPENAI_MODEL. Model names and provider credentials are not shown in the primary product UI.

Lead Agent troubleshooting

Model availability and feature support depend on the API project and credentials configured on the server. Uzoma does not assume that a model string is accessible merely because it is present in OPENAI_MODEL, and it does not silently select a fallback model. After changing the model, fully restart npm run dev.

Provider failures are mapped to safe categories for unavailable or unsupported models, invalid credentials, insufficient quota, rate limits, malformed structured output, outages, and unknown errors. Public errors never include raw provider messages, request IDs, credentials, project identifiers, or response bodies.

When the key is missing or the provider fails, Uzoma does not impersonate a live response. The create-request dialog offers a separate, explicit Use deterministic demo plan action. Those jobs are stored as agentMode: deterministic_demo; successful API plans are stored as agentMode: live.

Lead Agent planning never deploys a contract, signs a transaction, sends a payment, or anchors a dossier. Fresh user-controlled anchoring remains a planned integration after local acceptance evidence is ready.

Requester priority and Lead Agent assurance are deliberately separate:

• Requester priority (Standard, High, or Critical) is the urgency and delivery importance selected by the requester. The Lead Agent never changes it.
• Assurance level (Low, Medium, or High) is the Lead Agent’s independent assessment of the controls, review, and verification required before acceptance.

High assurance does not mean a request is invalid or unsafe to build. It means stronger authority checks, evidence requirements, failure-path testing, and independent review should be satisfied before the delivery is accepted. A job can therefore correctly show both High priority and Assurance level: High.

DeFi and RWA relevance

The default Milestone Escrow request models a common DeFi and real-world-asset delivery problem: funds or value should move only after explicit authority checks, accepted milestones, timeout protection, adversarial testing, and independent review.

Uzoma does not execute escrow payments. It demonstrates the delivery and proof layer around contract work—how a milestone specification, implementation, tests, review, and final acceptance can remain connected and verifiable.

Architecture

Layer	Current status
Multi-agent delivery workflow	Implemented locally
Artifact generation and acceptance	Implemented locally
Deterministic Build Dossier	Implemented locally
Odra BuildDossierRegistry	Deployed on Casper Testnet
Demo dossier proof event	Confirmed on Casper Testnet
MCP specialist discovery	Planned integration
x402 settlement	Planned integration; mock delivery accounting
Browser wallet signing	Planned integration
Automatic anchoring of future jobs	Not enabled

The browser contains no private key handling, signing, contract-write, payment, or automatic-anchoring logic. Local workflow status and Casper anchor status are modeled separately.

Uzoma does not represent local workflow completion as an on-chain event; local and Casper proof statuses are modeled separately.

Real Casper Testnet proof

The public proof below is intentionally committed in lib/casper/demo-proof.json and exposed through the typed record in lib/casper/proof.ts.

Status: Anchored on Casper Testnet — Confirmed on-chain proof in the live Testnet registry.

The deployed on-chain component is Uzoma’s BuildDossierRegistry on Casper Testnet. The Milestone Escrow implementation shown in the demo is a reviewed delivery-artifact preview; it is not the deployed contract.

The confirmed Casper Event Standard record contains dossier ID 1, the creator account hash, job ID, dossier hash, artifact root, artifact count, accepted = true, and the recorded block time.

Verify the proof read-only

Install Casper client 5.0.1, then run:

cd contracts/build-dossier-registry
./scripts/verify-demo-anchor.sh

The script uses only read-only Casper RPC commands. It resolves the package and current contract, validates the generated schema against the deployed entry point, reads event __events[0], and decodes the complete DossierAnchored record. It does not request a secret key, sign, deploy, anchor, or submit a transaction. Public Testnet RPC rate limiting can occasionally require a later retry.

Run locally

Prerequisites:

• Node.js 20.19+, 22.13+, or 24+;
• npm;
• Rust nightly with wasm32-unknown-unknown for contract work;
• cargo-odra 0.1.7 and Odra 2.8.1 for the contract build;
• wasm-validate from WABT for WASM validation.

npm install
npm run dev

Open http://localhost:3000.

Frontend quality commands:

npm test
npm run lint
npm run typecheck
npm run build

Contract tests and build

cargo +nightly test --manifest-path contracts/build-dossier-registry/Cargo.toml --all-targets
cd contracts/build-dossier-registry
cargo odra build
wasm-validate wasm/BuildDossierRegistry.wasm

The optimized WASM is reproducible build output and is intentionally ignored. Contract source, the lockfile, generated schemas, deterministic demo fixture, verification tools, and guarded operator templates belong in version control.

Demo flow for judges

1. Open Create Build Request and show a completed LIVE AGENT PLAN, including Assurance Level, rationale, specialist assignments, and acceptance criteria.
2. Open the generated local dossier and point out that new work is not automatically Casper-anchored.
3. Open the completed seeded demo-escrow Build Dossier.
4. In Casper Testnet Anchor, show the registry package hash, install transaction, anchor transaction, accepted state, artifact root, timestamp, and block.
5. Optionally run ./scripts/verify-demo-anchor.sh to reproduce the proof through read-only RPC verification.

Implementation boundaries

Uzoma intentionally separates planning, local delivery orchestration, and on-chain proof.

• New request planning can run through the configured server-side Lead Agent.
• Specialist execution, artifact generation, reviews, and receipt accounting are deterministic local workflow state in the current build.
• Only the seeded demo-escrow Build Dossier has confirmed Casper Testnet proof.
• New jobs are not automatically anchored.
• Receipt amounts are delivery accounting only; no payment or settlement is executed.
• MCP discovery, x402 settlement, browser wallet connection, and user signing are planned integration surfaces.
• The current registry deployment and proof are Testnet-only.

See contracts/build-dossier-registry/README.md for the contract and operator workflow, and SUBMISSION_CHECKLIST.md for the final submission handoff.
