# Lifecycle Status

This document tracks the lifecycle status of every specification in this repository.

## Status definitions

| Status | Meaning |
|---|---|
| **Active** | Current canonical specification. Implementations should conform to this version. Backwards-compatible clarifications may land as minor version bumps. |
| **Advisory** | Specification is published but the corresponding runtime engine is not yet generally available. Treat as forward-looking reference. |
| **Draft** | Published for community review. Conformance is not required. Subject to material change before version 1.0. |
| **Deprecated** | Superseded by a newer version. Retained for historical reference. |

## Current status

| Specification | Version | Status | Runtime availability | Notes |
|---|---|---|---|---|
| [Ontology](../ontology/spec.md) | 1.0 | Active | Available | Vocabulary stable. Sanitized public subset. |
| [ATS](../ats/spec.md) | 1.0 | **Deprecated** | Retired 2026-05-22 | Folded into L2 Routing `q_empirical`. Spec + schema retained for historical consumers (AIN-243). |
| [AAMC](../aamc/spec.md) | 1.1 | **Deprecated** | Retired 2026-05-22 | 5-voter deliberation retired; compliance-veto survives as Routing `M_allowed`. Spec retained (AIN-243). |
| [Annex IV mapping](../annex-iv/mapping.md) | 1.0 | Active | `GET /v1/audit/{agent_id}/annex-iv` live (minimal JSON) | Full signed zip envelope spec in progress; see [minimal-export.schema.json](../annex-iv/schema/minimal-export.schema.json). |
| [A2A](../a2a/spec.md) | 1.0 | Active | Available via Model Context Protocol transport | Native API targeted for follow-up sprint after MSG-4 a2a-sync. |
| [Auth](../auth/spec.md) | 1.0 | Active | Available via SDK and dashboard | API key format, transport, deprecation, and rotation. |
| [Alignment matrix](./alignment.md) | 1.0 | Active | N/A | Living document. |

## Forward-looking specifications

The following specifications are anticipated but not yet drafted. Listed here so that implementers and standards bodies tracking Ainfera have visibility.

| Working title | Anticipated version | Status | Notes |
|---|---|---|---|
| Settlement primitive | 0.x | Not started | Will compose with x402 Foundation when the x402 spec stabilizes. |
| Bundle export | 0.x | Not started | Will define the export envelope for Annex IV technical documentation bundles. |
| Routing outcomes (`q_empirical`) | 0.x | In progress | Replaces retired ATS trust-score surface; internal routing canon (AIN-243). |
| Ontology v2.0 | 2.0 | Not started | Will reconcile with W3C Verifiable Credentials and DID Core. |

## Deprecation policy

When a specification is superseded:

1. The deprecated version is moved to a `legacy/` subdirectory.
2. The Status table here is updated.
3. A migration guide is published alongside the new version.
4. The deprecated version remains accessible under its original tag (e.g. `ats-v1.0` continues to resolve even after `ats-v2.0` ships).

We do not delete published specifications. Implementers who built against a published version retain access to that version indefinitely.

## Machine-readable schemas (AIN-206)

| Spec | Schema | Validator |
|------|--------|-----------|
| Audit event | `ontology/schema/api-audit-event.schema.json` | `scripts/validate_audit_event_schema.py` |
| Annex IV export | `annex-iv/schema/minimal-export.schema.json` | `scripts/validate_annex_iv_schema.py` |
| ATS trust score *(deprecated)* | `ats/schema/trust-score-computation.schema.json` | `scripts/validate_ats_schema.py` |
| AAMC deliberation *(deprecated)* | `aamc/schema/deliberation.schema.json` | `scripts/validate_aamc_schema.py` |

Run all: `python scripts/validate_all_schemas.py`. Versioned URLs: [`spec-urls.json`](./spec-urls.json).

## Conformance

A system claiming conformance to an Ainfera specification at a given version MUST:

- Implement the primitives described in the specification's normative sections.
- Cite the specification version in any AgentCard, Receipt, or AuditEvent it emits.
- Disclose any deviations or extensions.

Conformance is self-attested. Ainfera Inc. does not currently operate a certification program. If you require third-party verification, please contact us.
