+# AGNTCY Alignment
+
+This folder documents how SentryAgent.ai AgentIdP aligns with the **AGNTCY** open standard for AI agent identity, interoperability, and governance.
+
+## What is AGNTCY?
+
+AGNTCY is an open standard from the **Linux Foundation** that defines how AI agents should be identified, authenticated, and governed — across organisations, platforms, and ecosystems.
+
+The core premise: AI agents are **non-human identities** that need the same rigour as human identities — unique identifiers, authenticated credentials, lifecycle management, and audit trails — but designed from the ground up for autonomous software rather than bolted onto human auth systems.
+
+## Why it matters
+
+Without a standard like AGNTCY, every team building AI agents invents its own identity model. Agents cannot interoperate. There is no portable way to say "this agent is who it claims to be." Governance is impossible at scale.
+
+AGNTCY solves this by defining:
+- A universal **agent identity model** (what an agent identity contains)
+- A **credential and authentication model** (how agents prove their identity)
+- A **lifecycle model** (how agents are provisioned, suspended, and retired)
+- An **audit and accountability model** (what must be logged and retained)
+
+## SentryAgent.ai's Position
+
+SentryAgent.ai AgentIdP implements the AGNTCY non-human identity model as a **free, open-source reference implementation** — the first of its kind. Any developer can run it, any AGNTCY-compliant system can interoperate with it.
+

+# AGNTCY Alignment Mapping
+
+This document maps each AGNTCY standard concept to the corresponding AgentIdP implementation. It is the authoritative reference for AGNTCY compliance claims.
+
+---
+
+## AGNTCY Core Concepts
+
+AGNTCY defines five foundational concepts for AI agent identity:
+
+| AGNTCY Concept | Description |
+|----------------|-------------|
+| **Non-Human Identity** | Agents are first-class identities — not service accounts, not user proxies |
+| **Agent Registry** | Authoritative directory of registered agent identities with stable, immutable IDs |
+| **Credential Management** | Secure issuance, rotation, and revocation of agent credentials |
+| **Authentication** | Standardised protocol for agents to prove their identity |
+| **Lifecycle Management** | Defined states for agent provisioning, suspension, and retirement |
+| **Audit and Accountability** | Immutable event log of all agent actions for governance and compliance |
+
+---
+
+## Implementation Mapping
+
+### Non-Human Identity
+
+AGNTCY requires agents to be treated as first-class identities with their own identity model — not mapped onto human user accounts.
+
+| AGNTCY Requirement | AgentIdP Implementation | Status |
+|--------------------|------------------------|--------|
+| Unique, immutable agent identifier | `agentId` (UUID, system-assigned at registration, never changes) | ✅ Implemented |
+| Human-readable stable name | `email` field — unique email-format identifier per agent | ✅ Implemented |
+| Identity metadata | `agentType`, `version`, `capabilities`, `owner`, `deploymentEnv` fields | ✅ Implemented |
+| Capability declaration | `capabilities` array — `resource:action` strings declaring agent permissions | ✅ Implemented |
+| Identity separate from human users | Agents have their own registry, credential model, and token flow — no user accounts | ✅ Implemented |
+
+**API endpoints:** `POST /api/v1/agents`, `GET /api/v1/agents/{agentId}`
+
+---
+
+### Agent Registry
+
+AGNTCY requires a centralised, queryable registry of agent identities.
+
+| AGNTCY Requirement | AgentIdP Implementation | Status |
+|--------------------|------------------------|--------|
+| Register new agent identity | `POST /api/v1/agents` | ✅ Implemented |
+| Retrieve agent by stable ID | `GET /api/v1/agents/{agentId}` | ✅ Implemented |
+| List and filter registered agents | `GET /api/v1/agents?owner=&agentType=&status=` | ✅ Implemented |
+| Update agent metadata | `PATCH /api/v1/agents/{agentId}` | ✅ Implemented |
+| Soft-delete retired agents (record retained) | `DELETE /api/v1/agents/{agentId}` → status: `decommissioned`, record persisted | ✅ Implemented |
+| Enforce uniqueness of agent identity | `email` unique constraint — `409 AGENT_ALREADY_EXISTS` on duplicate | ✅ Implemented |
+
+---
+
+### Credential Management
+
+AGNTCY requires secure credential issuance with rotation and revocation support.
+
+| AGNTCY Requirement | AgentIdP Implementation | Status |
+|--------------------|------------------------|--------|
+| Issue agent credentials | `POST /api/v1/agents/{agentId}/credentials` — generates `client_id` + `client_secret` | ✅ Implemented |
+| Secret never stored in plaintext | `client_secret` stored as bcrypt hash; plaintext returned once only | ✅ Implemented |
+| Multiple active credentials per agent | An agent can hold multiple active credentials simultaneously | ✅ Implemented |
+| Credential rotation | `POST /api/v1/agents/{agentId}/credentials/{credentialId}/rotate` | ✅ Implemented |
+| Credential revocation | `DELETE /api/v1/agents/{agentId}/credentials/{credentialId}` | ✅ Implemented |
+| Credential lifecycle tracking | `status` field: `active` / `revoked`; `revokedAt` timestamp | ✅ Implemented |
+| Optional credential expiry | `expiresAt` field on credential generation | ✅ Implemented |
+
+---
+
+### Authentication
+
+AGNTCY requires a standardised, interoperable authentication protocol for agents.
+
+| AGNTCY Requirement | AgentIdP Implementation | Status |
+|--------------------|------------------------|--------|
+| Standardised auth protocol | OAuth 2.0 Client Credentials grant (RFC 6749 §4.4) | ✅ Implemented |
+| Signed, verifiable tokens | RS256 JWT access tokens — any party with the public key can verify | ✅ Implemented |
+| Token introspection | `POST /api/v1/token/introspect` — RFC 7662 compliant | ✅ Implemented |
+| Token revocation | `POST /api/v1/token/revoke` — RFC 7009 compliant | ✅ Implemented |
+| Scope-based access control | `agents:read`, `agents:write`, `tokens:read`, `audit:read` scopes | ✅ Implemented |
+| Token lifetime enforcement | 1-hour JWT expiry, enforced at verification | ✅ Implemented |
+| Revocation durability | Revocations persisted to PostgreSQL + Redis | ✅ Implemented |
+
+**Token claims align with AGNTCY identity model:**
+
+| JWT Claim | AGNTCY Meaning |
+|-----------|----------------|
+| `sub` | The agent's stable `agentId` — the AGNTCY non-human identity reference |
+| `client_id` | The credential that authenticated this token request |
+| `scope` | Declared capabilities granted for this token |
+| `jti` | Unique token ID — enables precise revocation |
+
+---
+
+### Lifecycle Management
+
+AGNTCY defines a mandatory lifecycle for agent identities.
+
+| AGNTCY State | AgentIdP Status | Behaviour |
+|-------------|-----------------|-----------|
+| Provisioned / Active | `active` | Agent can authenticate and obtain tokens |
+| Suspended | `suspended` | Agent cannot obtain new tokens; existing tokens expire naturally |
+| Decommissioned / Retired | `decommissioned` | Permanent — all credentials revoked, agent cannot authenticate, record retained |
+
+| AGNTCY Requirement | AgentIdP Implementation | Status |
+|--------------------|------------------------|--------|
+| Defined lifecycle states | `status` enum: `active`, `suspended`, `decommissioned` | ✅ Implemented |
+| Irreversible decommission | `decommissioned` status cannot be reversed via API | ✅ Implemented |
+| Credential cascade on decommission | All active credentials revoked when agent is decommissioned | ✅ Implemented |
+| State transitions audited | Every status change writes an `agent.suspended`, `agent.reactivated`, or `agent.decommissioned` audit event | ✅ Implemented |
+
+---
+
+### Audit and Accountability
+
+AGNTCY requires an immutable, queryable audit log of all significant agent actions.
+
+| AGNTCY Requirement | AgentIdP Implementation | Status |
+|--------------------|------------------------|--------|
+| Immutable audit log | `audit_events` table — append-only, no API delete/update | ✅ Implemented |
+| Automatic event capture | 12 event types captured automatically across all services | ✅ Implemented |
+| Query and filter audit events | `GET /api/v1/audit` with filters: `agentId`, `action`, `outcome`, `fromDate`, `toDate` | ✅ Implemented |
+| Retrieve individual event | `GET /api/v1/audit/{eventId}` | ✅ Implemented |
+| Event retention | 90-day retention enforced at query layer (free tier) | ✅ Implemented |
+| Auth failure logging | `auth.failed` event on every failed `POST /token` attempt | ✅ Implemented |
+
+**Audited events (12 total):**
+
+| Event | Trigger |
+|-------|---------|
+| `agent.created` | New agent registered |
+| `agent.updated` | Agent metadata changed |
+| `agent.suspended` | Agent suspended |
+| `agent.reactivated` | Agent reactivated from suspended |
+| `agent.decommissioned` | Agent permanently decommissioned |
+| `token.issued` | Access token issued |
+| `token.revoked` | Access token revoked |
+| `token.introspected` | Token introspection called |
+| `credential.generated` | New credentials generated |
+| `credential.rotated` | Credential rotated |
+| `credential.revoked` | Credential revoked |
+| `auth.failed` | Authentication attempt failed |
+
+---
+
+## Compliance Status Summary
+
+| AGNTCY Domain | Phase 1 Status | Notes |
+|---------------|----------------|-------|
+| Non-Human Identity | ✅ Fully implemented | Immutable IDs, typed metadata, capability declarations |
+| Agent Registry | ✅ Fully implemented | Full CRUD, pagination, soft-delete |
+| Credential Management | ✅ Fully implemented | Generate, rotate, revoke, bcrypt storage |

+
+---
+
+## Interoperability
+
+An agent registered in AgentIdP can be identified by any AGNTCY-compliant system using its `agentId` (UUID). The JWT access token carries the `sub` claim (= `agentId`), making the agent's identity verifiable by any party that holds the AgentIdP RS256 public key.
+
+To verify an AgentIdP token in an external system:
+
+1. Obtain the AgentIdP RS256 public key (`JWT_PUBLIC_KEY` from the server operator)
+2. Verify the JWT signature using RS256
+3. The `sub` claim is the agent's stable AGNTCY-aligned identity reference
+4. The `scope` claim declares the agent's authorised capabilities for this token
+
+This is the same verification model used across all OAuth 2.0 / OIDC systems — purpose-built for machine-to-machine interoperability.

+## Context
+AGNTCY is the Linux Foundation open standard for AI agent identity, interoperability, and governance. AgentIdP implements the non-human identity model defined by AGNTCY. This document makes that alignment explicit and verifiable.
+
+## Goals
+- Engineers and architects can verify AGNTCY compliance without reading the full standard
+- The mapping is explicit: each AGNTCY concept is matched to a specific AgentIdP API feature
+- Both compliant and pending/out-of-scope items are documented honestly

+- Multi-stage build: `builder` stage compiles TypeScript; `production` stage copies `dist/` only

+- No dev dependencies in production image — only `npm ci --omit=dev`

+## Context
+The SDK wraps the AgentIdP REST API. It must handle authentication transparently — caller provides `clientId` + `clientSecret`, SDK manages token acquisition and refresh automatically.
+
+## Architecture
+- Single entrypoint: `sdk/src/index.ts` exports `AgentIdPClient` and all types
+- `AgentIdPClient` constructor takes `{ baseUrl, clientId, clientSecret }`
+- Internal `TokenManager` handles token acquisition, caching, and refresh (re-issues when expired)
+- Four service classes: `AgentRegistryClient`, `CredentialClient`, `TokenClient`, `AuditClient`
+- `AgentIdPClient` composes all four
+- HTTP: native `fetch` (Node 18+ built-in) — no axios dependency
+- Types: re-exported from `sdk/src/types.ts` — mirrors the main app types
+
+## Standards
+- TypeScript strict mode, zero `any`
+- DRY: shared `request()` helper handles auth header, JSON parse, error mapping
+- All errors are typed `AgentIdPError` with `code` and `message`
+- JSDoc on all public methods
+
+## Package structure
+```
+sdk/
+  src/
+    index.ts          — exports AgentIdPClient + all types
+    client.ts         — AgentIdPClient (composes all services)

+## Why
+Bedroom developers currently must write raw HTTP calls to use AgentIdP. A Node.js SDK removes that friction — developers install one package and get a fully typed, auto-authenticating client. This is a Phase 1 P1 deliverable and a core developer experience improvement.
+
+## What Changes
+- New `sdk/` directory at project root containing a self-contained TypeScript npm package
+- `AgentIdPClient` class: handles auth, token refresh, and exposes typed methods for all 14 endpoints
+- Covers all four services: AgentRegistry, Credentials, Token, AuditLog
+- Full TypeScript types — zero `any`, strict mode
+- Published as `@sentryagent/idp-sdk` (package name)
+
+## What Does Not Change
+- No API changes
+- No changes to the main application source

+# @sentryagent/idp-sdk
+
+Node.js SDK for the [SentryAgent.ai AgentIdP](https://sentryagent.ai) — the open-source Identity Provider for AI agents.
+
+Handles token acquisition and caching automatically. Covers all 14 AgentIdP API endpoints.
+
+---
+
+## Requirements
+
+- Node.js 18 or later (uses native `fetch`)
+- A running AgentIdP server
+- A registered agent with a valid `clientId` and `clientSecret`
+
+---
+
+## Installation
+
+```bash
+npm install @sentryagent/idp-sdk
+```
+
+---
+
+## Quick start
+
+```typescript
+import { AgentIdPClient } from '@sentryagent/idp-sdk';
+
+const client = new AgentIdPClient({
+  baseUrl: 'http://localhost:3000',
+  clientId: 'your-agent-id',       // the agent's agentId (UUID)
+  clientSecret: 'your-client-secret',
+});
+
+// List agents — token is acquired and cached automatically
+const { data: agents } = await client.agents.listAgents();
+console.log(agents);
+```
+
+---
+
+## Configuration
+
+```typescript
+const client = new AgentIdPClient({
+  baseUrl: 'http://localhost:3000',
+  clientId: 'a1b2c3d4-e5f6-7890-abcd-ef1234567890',
+  clientSecret: 'your-client-secret',
+  // Optional: restrict scopes. Defaults to all four scopes.
+  scopes: ['agents:read', 'tokens:read'],
+});
+```
+
+| Option | Required | Description |
+|--------|----------|-------------|
+| `baseUrl` | Yes | Base URL of the AgentIdP server |
+| `clientId` | Yes | The agent's `agentId` (UUID) |
+| `clientSecret` | Yes | The credential secret |
+| `scopes` | No | OAuth 2.0 scopes to request. Defaults to all four. |
+
+---
+
+## Token management
+
+The SDK fetches and caches access tokens automatically. A new token is requested when the cached token is within 60 seconds of expiry.
+
+```typescript
+// Force a fresh token on the next request (e.g. after rotating credentials)
+client.clearTokenCache();
+```
+
+---
+
+## Agent Registry
+
+```typescript
+// Register a new agent
+const agent = await client.agents.registerAgent({
+  email: 'classifier-v2@myorg.ai',
+  agentType: 'classifier',
+  version: '2.0.0',
+  capabilities: ['text-classification', 'sentiment-analysis'],
+  owner: 'platform-team',
+  deploymentEnv: 'production',
+});
+console.log(agent.agentId); // UUID assigned by AgentIdP
+
+// List agents
+const { data, total } = await client.agents.listAgents({ status: 'active', limit: 20 });
+
+// Get a single agent
+const agent = await client.agents.getAgent('a1b2c3d4-...');
+
+// Update an agent
+const updated = await client.agents.updateAgent('a1b2c3d4-...', {
+  version: '2.1.0',
+  capabilities: ['text-classification', 'sentiment-analysis', 'intent-detection'],
+});
+
+// Decommission (irreversible)
+await client.agents.decommissionAgent('a1b2c3d4-...');
+```
+
+---
+
+## Credentials
+
+```typescript
+// Generate a credential — clientSecret shown once, store it securely
+const cred = await client.credentials.generateCredential('a1b2c3d4-...');
+console.log(cred.clientSecret); // only available here
+
+// List credentials
+const { data: creds } = await client.credentials.listCredentials('a1b2c3d4-...');
+
+// Rotate — same credentialId, new secret, old secret immediately invalid
+const rotated = await client.credentials.rotateCredential('a1b2c3d4-...', 'cred-uuid');
+console.log(rotated.clientSecret); // new secret — store immediately
+
+// Revoke
+await client.credentials.revokeCredential('a1b2c3d4-...', 'cred-uuid');
+```
+
+---
+
+## Token operations
+
+```typescript
+// Introspect — check whether a token is active
+const result = await client.tokens.introspectToken(someToken);
+if (result.active) {
+  console.log('Token is valid, expires at', result.exp);
+} else {
+  console.log('Token is expired or revoked');
+}
+
+// Revoke — immediately invalidates the token
+await client.tokens.revokeToken(someToken);
+```
+
+---
+
+## Audit log
+
+```typescript
+// Query audit events
+const { data: events } = await client.audit.queryAuditLog({
+  agentId: 'a1b2c3d4-...',
+  action: 'token.issued',
+  outcome: 'success',
+  fromDate: '2026-03-01T00:00:00Z',
+  toDate: '2026-03-31T23:59:59Z',
+  limit: 50,
+});
+
+// Get a single event
+const event = await client.audit.getAuditEvent('event-uuid');
+```
+
+---
+
+## Error handling
+
+All API errors are thrown as `AgentIdPError`:
+
+```typescript
+import { AgentIdPClient, AgentIdPError } from '@sentryagent/idp-sdk';
+
+try {
+  await client.agents.getAgent('non-existent-id');
+} catch (err) {
+  if (err instanceof AgentIdPError) {
+    console.error(err.code);       // e.g. 'AgentNotFoundError'
+    console.error(err.httpStatus); // e.g. 404
+    console.error(err.message);    // human-readable description
+  }
+}
+```
+
+---
+
+## Available scopes
+
+| Scope | What it allows |
+|-------|----------------|
+| `agents:read` | Read agent records |
+| `agents:write` | Create, update, decommission agents |
+| `tokens:read` | Introspect tokens |
+| `audit:read` | Query audit logs |
+
