The DecOps Stack

Signalnio is the architect layer. Decide.fyi is the deterministic engine. Krafthaus is the operator interface.

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

Workspace for product and growth teams to run scoped decisions and receive one clear recommendation memo.

  • Decision credits and run flow
  • Memo artifacts and risk checks
  • History and operator workflow

Decision Flow Example

Input

Scoped decision payload

{
  "question": "Should Starter be $15 or $20?",
  "options": ["$15 monthly", "$20 monthly"],
  "guardrail": "Preserve margin floor and support SLA"
}

Engine response (Decide.fyi)

Decision API output

{
  "verdict": "ALLOWED",
  "recommended_option": "$15 monthly",
  "request_id": "req_8g2m1k",
  "risk_checks": ["margin_floor", "support_sla"]
}

Interface output (Krafthaus)

Operator memo snapshot

Recommendation: choose $15 monthly starter anchor
Expected impact: directional conversion lift vs baseline
Risk checks: pass (margin floor + SLA)
Delivery: decision memo + audit trace

One sample decision moving through the full chain: Signalnio structure → Decide.fyi API verdict → Krafthaus memo output.
