Nexum is the platform that turns vague prompts into binding PRDs, manages mid-flight scope changes, and settles milestones with evidence.
@Nexum is Milestone 2 deliverable ready for escrow release?
M2 passed all 12 automated checks & staging preview verified. Awaiting your 1-click cryptographic sign-off.
✓ AST syntax tree validated (0 errors)
✓ 12 unit & integration tests passing
✓ UI inspector captured visual proof
Seal: sha256_#9b3e1f7a8c42...
Visual Staging Proof & SSR Hooks • 12/12 Automated Checks Passed
PR #14 Schema Migrations & RBAC • All criteria satisfied
Webhook Signature Listener & Rails • Sandbox harness passing
The intelligent system that never sleeps. Turns vague prompts into binding PRDs. Intercepts scope creep before it starts.
Turn vague chats into testable acceptance criteria.
Direct client chats create memory leaks. Nexum’s intake agent parses natural conversation into structured JSON requirements with machine-verifiable pass/fail criteria.
“I need a Next.js digital storefront with Stripe and PayPal checkout. Maximum budget is $5,500, but I want to offer $4,000 first. Must be done by Nov 20.”
No Conversational Ambiguity
Every milestone contains unambiguous pass/fail criteria. If requirements shift, the state machine detects material diffs automatically.
Zero Strategy Leakage
Internal notes and maximum willing spend are cryptographically stripped before sending the proposal brief to the freelancer.
Autonomous proof-of-execution verifier.
Never release funds on blind trust. Nexum boots an autonomous staging inspector, tests demo credentials, runs AST code analysis, and captures high-resolution visual proof before escrow can be released.
Inspected by Nexum Autonomous Cascade • Target: https://staging.shopkart.com
Headless UI & Demo Credentials
Freelancers provide staging links and credentials in 1 unified field. Nexum simulates authenticated user sessions and captures immutable visual snapshots.
Multi-Model AST Cascade
Combines AST syntax parsing, Groq LPU fast validation, and Gemini reasoning to verify code changes before notifying the client.
Mid-flight scope changes routed without rewriting history.
When a client requests extra features during development, Section 14 evaluates the agreement and branches it into follow-on milestones. Completed work is permanently sealed.
“Add Multi-Currency in M2”
Detects M1 is accepted & M2 is active. Routes to M4 fork.
Completed work never reopened
Dual approval required
6 Deterministic Routes
New feature, unaccepted revision, follow-on milestone, clarification, scope reduction, or defect correction. No unstructured ambiguity.
Dual Sign-Off Reset
Any material cost or timeline adjustment generates a new agreement snapshot that both parties must cryptographically sign.
No contract is active until both parties sign the same hash.
Every proposal, counteroffer, and milestone allocation snapshots scope and terms into a SHA-256 hash. If one party alters a single character, consensus is immediately voided.
Schema migrations & OAuth2 tenant isolation.
SSR product catalog and checkout pipeline.
PayPal webhook deduplication listener.
Multi-currency conversion checkout module.
Cryptographic Version Snapshots
Draft Proposal $\rightarrow$ Counteroffer Review $\rightarrow$ Consensus Agreement. Full immutable lineage with zero unrecorded commitments.
Non-Autonomous AI Security
AI suggests pricing curves and drafts specs, but is cryptographically prevented from signing agreements or releasing funds.
Run your contracts & escrow from Telegram.
Operate your projects directly from your phone. Our verified @NexumDev_Bot gateway relays voice memos, pushes instant milestone alerts, and lets you approve code deliverables with 1 tap.

Leave a voice memo while walking to a meeting. Nexum AI transcribes, extracts actionable deliverable boundaries, and updates the workspace agreement.
Zero App Install Required
1-click deep link pairs your existing Telegram account securely with cryptographic OTP authorization. No custom app download needed.
A network timeout does not mean payment failed.
Traditional platforms prompt users to “Try Again” after an HTTP timeout, double-charging credit cards. Nexum transitions to UNKNOWN and uses idempotent reconciliation.

✔ Webhook verified: PAYMENT.CAPTURE.COMPLETED (captureId: 7CD9921)

Payment Readiness Card
Prior to checkout, contract amounts are locked server-side. Unobservable fields are transparently labeled rather than guessed.
OECD Compliance Standard
Clear legal separation between payment capture and bank credit. Standard PayPal capture is never mislabeled as unconditional escrow.
Every decision mathematically sealed in an audit ledger.
Cryptographic event streaming ensures neither party can deny approvals, dispute deliveries retroactively, or hide private negotiation terms.
Exportable Audit Packages

Post-Project Verified Reviews Only
Reputation scores can only be submitted after actual milestone captures. No fabricated reviews or self-awarded stars.
Universal Consensus™
It seals itself.
PRDs, quotes, and approvals hashed automatically.
Both workspaces talk.
Client and agency in continuous mathematical sync.
Guards your strategy.
Budgets, internal notes, and ceilings stay confidential.
Changes don't break past.
Scope additions fork into follow-on milestones.
Zero blind retries.
Timeouts safely enter bounded reconciliation.
Autonomous Proof-of-Execution
Automated test suites, AST syntax parsing, and headless staging UI inspection with demo credentials before escrow release.
Telegram Mobile Gateway
Run your workspace directly from your phone. Approve milestones, review deliverables, receive voice memos, and release escrow via @NexumDev_Bot.
Dual AI & Bilateral Consensus
Dedicated AI copilots for client and freelancer operating behind the FR-03 privacy firewall with dual SHA-256 agreement seals.
SDK. API. PROTOCOL.Build anything on Nexum.
import { Nexum } from "@nexum/sdk";
const nexum = new Nexum({ apiKey: process.env.NEXUM_KEY });

Built for contractual discipline.
Three deterministic safeguards that permanently eliminate scope drift, hidden checkout spreads, and private budget leakage.
Milestone-Aware Routing
Scope additions branch into isolated follow-on milestones. Historical work is sealed and immutable.
Radical Fee Transparency
Contract figures locked server-side before checkout. Every provider fee is explicitly disclosed.
Consent-Aware Firewall
Client maximum budgets and negotiation strategy are physically stripped before proposals leave the workspace.
A network timeout is not proof that payment failed.
Marketplaces blindly prompt buyers to "Try Again" on HTTP drops, triggering double charges. Nexum transitions to UNKNOWN and reconciles idempotently before retrying.
Deterministic Settlement Lifecycle
Cryptographic Lock
Idempotency key req_98bfa2 locks contract state before calling payment rails.
Network Intercept
Connection severed in transit. Client UI halts duplicate billing attempts immediately.
Automated Invariant
Status shifts to UNKNOWN. Daemon enqueues idempotent status check with provider.
Verified Settlement
HMAC webhook signature verified. Milestone transitions to paid with zero duplicates.
req_98bfa2 • Rail: PayPal Orders v2Strict server-side idempotency stops duplicate card charges.
Every PayPal event is cryptographically validated via HMAC-SHA256.
Automated background daemon checks status without buyer friction.
