Evidence
How evidence supports decisions, transitions, corrections, and milestone acceptance.
Evidence
Evidence is what keeps decisions in O2A explainable. When something changes — a lifecycle transition, a financial correction, a milestone accepted — evidence is the record of why. It stays linked to the specific fact or decision it justifies.
How It Works
Evidence explains a decision and can support several kinds of change: lifecycle transitions, financial corrections, and milestone acceptance. In each case it remains bound to the fact or decision it supports, so the link from "what changed" to "why it changed" is never lost.

- Evidence supports lifecycle transitions.
- Evidence supports financial corrections.
- Evidence supports milestone acceptance.
- Evidence stays linked to the fact or decision it supports.
Why It Matters
Because financial history is append-only and lifecycles are gated, the system needs a durable account of the reasoning behind each change. Evidence supplies that account and keeps it attached to its subject, so an auditor or agent can always trace a transition or correction back to its justification. This underpins the Milestone model, where acceptance in V1 is a human-attested act, and complements the append-only discipline of Financial Truth.
