What is a Role Brain?

A Role Brain is a persistent decision-pattern repository that captures the tacit knowledge and instincts of key personnel. When an executive departs, their Role Brain remains as a corporate asset, allowing a successor to operate at full capacity from Day 1.

How does StackFast differ from standard RAG implementations?

Standard RAG retrieves text without understanding context. StackFast provides a reasoning layer that applies judgment through structured logic, builds persistent Role Brains that compound over time, and enforces knowledge sovereignty through a 3-layer governance gate.

What is Knowledge Sovereignty?

Knowledge Sovereignty means your organization's intelligence never leaks into third-party training sets. Every brain entry is tagged for compliance and M&A readiness, with audit trails generated automatically for EU AI Act, SOC2, and HIPAA compliance.

How does StackFast reduce Key-Person Risk?

StackFast captures executive decision patterns, client relationship nuances, and institutional knowledge into structured Role Brains. When key personnel leave, their judgment and instincts remain as a corporate asset, reducing onboarding time for replacements and preserving institutional intelligence.

Who it is for

Executives, operators, founders, PE portfolio leaders, and enterprise buyers who need to decide what to build, buy, replace, or quote in their AI stack.

Problem it solves

It cuts through generic AI wrapper claims and exposes whether a tool, vendor, or internal plan is defensible, governable, and close enough to the business object to create durable value.

Activation model

Checkout creates a paid audit project; a senior consultant administers discovery and every deliverable receives senior review before delivery.

Proof and source paths

Decision routing for AI Stack Audit is live
Audit project and credit-ledger schema exists
CogentCast authority flywheel is producing public audit-positioning material
Live Stripe products and one-time prices are wallet-routed

Capabilities

Connector proof

Catalog is not the same as customer-ready.

This product only becomes market-ready after a real host mounts the entitled tools, a safe call succeeds, metering records the event, and a customer-safe receipt exists. Until then, the page shows the strongest proven status without rounding up.

Catalog

Runtime registry and product manifest are present.

Entitlement

Entitlement boundary is not declared.

Callable

3 tool(s) declared with no missing V1 tools.

Metering

MCP calls are routed through the metering receipt path.

Customer validated

Pending fresh host-surface call receipt.

Runtime registry status

Primary registry

stackfast.ai/api/mcp

Status

live public mcp

Install gate

Checkout path is live only when wallet key stripe.audit_price_ids resolves all three one-time Stripe prices.

Callable tools

stackfast.audit.purchase

Missing or gated tools

No missing tools declared for the current V1 boundary.

Public copy describes deliverables and implementation-layer components without exposing internal decision frameworks.
