Deliverables, not subscriptions

Choose the tier that matches your engineering bandwidth. Every engagement produces concrete artifacts: specifications, code scaffolds or builds, tests, and evidence packs—delivered as standalone, client-specific software.

📦 What is always true (across tiers)

• Delivery is a Customer-Nyxi variant for your environment (standalone artifact, client-specific).
• Governance is applied only to declared irreversible sinks (explicit scope).
• Semantics are fail-closed at execution time: UNKNOWN / INVALID ⇒ no execution.

Tier 1 — Spec Pack

• Inventory and define irreversible sinks and where commit occurs.
• Write execution invariants:
  • conditions required for ALLOW
  • conditions that force VETO
• Define evidence requirements:
  • how we demonstrate VETO ⇒ no side effects
  • how we demonstrate ALLOW ⇒ side effects occurred

Tier 2 — Spec + Scaffold

Includes everything in Tier 1.

• Provide an integration scaffold aligned to your sink interfaces (no internal tooling exposure).
• Provide an initial test harness and example cases for ALLOW / VETO / UNKNOWN paths.

Tier 3 — Full Build

Includes everything in Tier 1 and Tier 2.

• Deliver the fully implemented governance layer integrated to your declared sinks.
• Deliver tests + evidence pack demonstrating veto/allow behavior at the irreversible boundary.

Tier 4 — Maintenance / Retainer

• Maintain the Customer-Nyxi variant as sink semantics, invariants, and integration contracts change.
• Add/adjust invariants and refresh the evidence pack when execution surfaces evolve.
• Provide ongoing engineering support for regression findings at the governed boundaries.

🧭 What we explicitly do not deliver

• No hosted platform, dashboards-as-a-service, or “we run it for you” operations.
• No claims of securing the entire system or certifying compliance.
• No governance of sinks you have not declared (no hidden scope).
