The DecOps Stack

Signalnio is the architect layer. Decide.fyi is the deterministic engine. Krafthaus is the forward-deployed product layer.

Layer 1 · Strategy

Signalnio

Defines system architecture, trust boundaries, and decision object standards across the stack.

  • Decision architecture
  • System design constraints
  • Cross-product narrative and governance

Layer 2 · Engine

Decide.fyi

Decision API for systems plus MCP notaries for agents, both producing deterministic, request-linked outputs.

  • Systems: REST decision endpoints
  • Agents: MCP notary endpoints
  • Audit-ready request IDs and verdicts

Layer 3 · Interface

Krafthaus

Workflow app layer for turning one consequential company workflow into governed execution.

  • Intake, rulebook, record, and handoff
  • Decision Memo app as one surface
  • Workflow App Sprint for custom surfaces

Decision Flow Example

Input

Workflow boundary payload

{
  "workflow": "quote_approval",
  "action": "send_nonstandard_terms",
  "guardrail": "Preserve margin floor"
}

Engine response (Decide.fyi)

Decision API output

{
  "verdict": "REVIEW",
  "action": "route_to_owner",
  "request_id": "req_8g2m1k",
  "decision_record": "attached"
}

Interface output (Krafthaus)

Workflow app handoff

Quote approval gate
Result: route nonstandard terms to owner
Rulebook: bound
Delivery: handoff + audit trace

One workflow boundary moving through the full chain: Signalnio structure → Decide.fyi API verdict → Krafthaus app handoff.
