Ethira-Ready Engineering Roadmap

Date: 2026-03-05
Owner: Ethira x VaryOn integration workstream

1. Purpose

This roadmap aligns implementation and rollout across:

1. tool and agent inventory,
2. contract assurance,
3. runtime alignment monitoring,
4. staged enforcement operations,
5. measurable operating metrics.

2. Canonical Architecture Model

Product surfaces (3)

1. AI Trust Registry = Provenance + Mandate + Meridian
2. Contract Assurance Monitor = Fidelity + Mandate + Meridian
3. Runtime Alignment Monitor = Drift + Fidelity + Mandate + Meridian + Threshold

Cross-product capability layer

• Runtime Enforcement & Resilience = Threshold + Drift + Fidelity + Mandate + Meridian
• Role: staged policy enforcement applied across products, especially Runtime Alignment and Contract Assurance.

3. Delivery Phases

Phase 1: Foundation and integration

Goal: establish consistent ingestion, scoring, eventing, and tenant-scoped operations.

Delivery outcomes:

1. Product endpoints integrated into Ethira flows.
2. Signed webhook consumption established.
3. Operational metrics and audit evidence flows validated.

Phase 2: Staged enforcement rollout

Goal: operationalize Threshold-backed policy gating safely.

Delivery outcomes:

1. alert and shadow policy modes active for baseline collection.
2. Selected controls promoted to soft_block.
3. Scoped hard_block applied on calibrated controls.

Phase 3: Scale and hardening

Goal: broaden coverage, improve precision, and standardize governance operations.

Delivery outcomes:

1. Expanded enforcement coverage by policy profile.
2. Stronger precision/recall performance by domain.
3. Repeatable audit and compliance evidence packaging.

4. Enforcement Rollout Rules

1. Start with alert and shadow for score-to-action validation.
2. Promote to soft_block for controls with stable evidence quality.
3. Promote to scoped hard_block only on calibrated controls.
4. Keep human override and audit payloads active across all policy modes.

5. Operator KPIs

• policy decision precision/recall by mode
• mean time to intervention
• false-positive and false-negative rate by policy profile
• evidence completeness for enforcement actions
