-## About Laravel
-
-Laravel is a web application framework with expressive, elegant syntax. We believe development must be an enjoyable and creative experience to be truly fulfilling. Laravel takes the pain out of development by easing common tasks used in many web projects, such as:
-
-- [Simple, fast routing engine](https://laravel.com/docs/routing).
-- [Powerful dependency injection container](https://laravel.com/docs/container).
-- Multiple back-ends for [session](https://laravel.com/docs/session) and [cache](https://laravel.com/docs/cache) storage.
-- Expressive, intuitive [database ORM](https://laravel.com/docs/eloquent).
-- Database agnostic [schema migrations](https://laravel.com/docs/migrations).
-- [Robust background job processing](https://laravel.com/docs/queues).
-- [Real-time event broadcasting](https://laravel.com/docs/broadcasting).
-
-Laravel is accessible, powerful, and provides tools required for large, robust applications.
-
-## Learning Laravel
-
-Laravel has the most extensive and thorough [documentation](https://laravel.com/docs) and video tutorial library of all modern web application frameworks, making it a breeze to get started with the framework. You can also check out [Laravel Learn](https://laravel.com/learn), where you will be guided through building a modern Laravel application.

+# Synapse Sentinel Core
+
+Event intake system for Synapse Sentinel. Receives certification results from gate workflows and stores them as events using Laravel Verbs.
+
+## Architecture
+
+```
+Gate Workflow → POST /api/webhooks/gate → Core
+                                           ↓ stores events
+                                      Laravel Verbs
+                                           ↓ projects to
+                                      CertificationState
+```
+
+## Installation
+
+```bash
+composer install
+cp .env.example .env
+php artisan key:generate
+php artisan migrate
+```
+
+## Webhook Endpoint
+
+### POST /api/webhooks/gate
+
+Receives certification results from gate workflows.
+
+**Headers:**
+- `Content-Type: application/json`
+- `X-Gate-Signature: <hmac-sha256>` (optional, required if `GATE_WEBHOOK_SECRET` is set)
+
+**Request Body:**
+```json
+{
+  "repository": "synapse-sentinel/core",
+  "sha": "abc123def456",
+  "verdict": "approved",
+  "reason": "All checks passed",
+  "checks": {
+    "tests": {"status": "pass", "coverage": 100},
+    "security": {"status": "pass"},
+    "syntax": {"status": "pass"}
+  },
+  "triggered_by": "pull_request",
+  "pr_number": 42
+}
+```
+
+**Response:**
+```json
+{"message": "ok"}
+```
+
+## Event Schema
+
+### CertificationRequested
+
+Fired when a certification process begins.
+
+| Field | Type | Required | Description |
+|-------|------|----------|-------------|
+| `repository` | string | yes | Full repository name (e.g., `owner/repo`) |
+| `sha` | string | yes | Git commit SHA |
+| `triggeredBy` | string | yes | What triggered the certification (`push`, `pull_request`, `workflow_dispatch`) |
+| `prNumber` | int | no | Pull request number if triggered by PR |
+| `branch` | string | no | Branch name |
+
+### CertificationCompleted
+
+Fired when certification finishes with a verdict.
+
+| Field | Type | Required | Description |
+|-------|------|----------|-------------|
+| `repository` | string | yes | Full repository name |
+| `sha` | string | yes | Git commit SHA |
+| `verdict` | string | yes | Result: `approved`, `rejected`, or `escalate` |
+| `reason` | string | no | Human-readable explanation |
+| `checks` | object | no | Detailed check results |
+| `triggeredBy` | string | no | What triggered the certification |
+| `prNumber` | int | no | Pull request number |
+
+### CertificationFailed
+
+Fired when certification encounters an error (distinct from rejection).
+
+| Field | Type | Required | Description |
+|-------|------|----------|-------------|
+| `repository` | string | yes | Full repository name |
+| `sha` | string | yes | Git commit SHA |
+| `error` | string | yes | Error message |
+| `stage` | string | no | Which stage failed (`tests`, `build`, `security`) |
+| `context` | object | no | Additional error context |
+
+## State Projection
+
+Events are projected to `CertificationState` which tracks:
+
+- `status`: `pending`, `completed`, or `failed`
+- `verdict`: `approved`, `rejected`, or `escalate` (when completed)
+- `repository`, `sha`, `branch`, `pr_number`
+- Timestamps: `requested_at`, `completed_at`, `failed_at`
+
+Query state:
+```php
+$state = CertificationState::load($certification_id);
+$state->isApproved();  // bool
+$state->isRejected();  // bool
+$state->isPending();   // bool
+$state->isFailed();    // bool
+```
+
+## Testing
+
+```bash
+php artisan test
+php artisan test --coverage
+```
