+# Contributing
+
+Thanks for helping improve LLM Gateway.
+
+The project values changes that make AI routing safer, easier to understand, easier to run,
+and easier to verify.
+
+## Contribution Areas
+
+Good first contribution areas:
+
+- documentation improvements
+- bridge health checks
+- provider adapters
+- tests for subscription discovery
+- dashboard clarity
+- metrics and observability
+- local-first routing policies
+- security hardening
+
+Larger contribution areas:
+
+- new subscription bridge implementations
+- policy engine improvements
+- context receipt support
+- reproducible run records
+- MCP tool support
+- database-backed audit trails
+
+## Ground Rules
+
+- Do not commit credentials, OAuth files, cookies, private keys, database dumps, training data,
+  logs with account data, private hostnames, or local machine paths.
+- Prefer explicit configuration through environment variables.
+- Keep default behavior local and safe.
+- Make operational state honest. Use `unknown`, `config_needed`, or `degraded` when the gateway
+  lacks evidence.
+- Add tests when changing routing, bridge behavior, authentication, or request validation.
+- Keep public examples generic.
+
+## Development Setup
+
+```bash
+npm install
+npm run dev
+```
+
+Build:
+
+```bash
+npm run build
+```
+
+Test:
+
+```bash
+npm test
+```
+
+Secret scan:
+
+```bash
+gitleaks dir . --redact
+```
+
+## Branch And Commit Style
+
+Use a short branch name:
+
+```text
+feature/subscription-health
+fix/bridge-timeout
+docs/quickstart
+```
+
+Use concise commit messages:
+
+```text
+docs: add subscription bridge guide
+fix(gateway): handle bridge timeout
+test(subscriptions): cover join flow
+```
+
+## Pull Request Checklist
+
+Before opening a pull request, confirm:
+
+- the change has a clear purpose
+- public docs do not contain private infrastructure details
+- build or tests were run
+- bridge or API changes have a smoke test
+- no credentials or account artifacts are included
+- the pull request explains risk and rollback if relevant
+
+## Adding A Provider
+
+Provider changes should include:
+
+- a descriptor or provider config entry
+- health behavior
+- model IDs
+- expected auth state
+- local test notes
+- error handling for missing CLI or unreachable bridge
+
+## Adding Documentation
+
+Documentation should be direct, testable, and operator-friendly.
+
+Prefer:
+
+- commands that can be copied
+- exact endpoint names
+- clear expected results
+- explicit security notes
+
+Avoid:
+
+- private URLs
+- screenshots with account data
+- local usernames or paths
+- long fake credentials
+- claims that are not supported by code
+
+## Maintainer Review
+
+The maintainer may ask for:
+
+- smaller pull requests
+- additional tests
+- simpler defaults
+- stronger security posture
+- clearer docs
+- removal of private data
+
+That review is part of keeping the gateway usable and publishable.

+# How To Work With LLM Gateway
+
+This guide covers the most common operator and contributor tasks.
+
+## 1. Run The Gateway Locally
+
+Install dependencies:
+
+```bash
+npm install
+```
+
+Start development mode:
+
+```bash
+npm run dev
+```
+
+Check health:
+
+```bash
+curl http://localhost:3100/health
+```
+
+Build:
+
+```bash
+npm run build
+```
+
+Start the built server:
+
+```bash
+npm run start
+```
+
+## 2. Configure A Local Provider
+
+Use environment variables for local provider URLs and bridge URLs. Avoid committing any
+machine-specific configuration.
+
+Common examples:
+
+```bash
+export PORT=3100
+export HOST=localhost
+export LOG_LEVEL=info
+```
+
+For provider and bridge variables, prefer your shell profile, process manager, or deployment
+environment. Keep real values out of git.
+
+## 3. Scan For Subscriptions
+
+Start the gateway, then run:
+
+```bash
+curl -X POST http://localhost:3100/api/subscriptions/scan \
+  -H "Authorization: Bearer <key>"
+```
+
+The scan checks the known subscription catalog and reports:
+
+- whether the CLI is installed
+- whether authentication can be detected
+- whether a bridge is already running
+- which model IDs the gateway can expose
+- whether the subscription can be joined or spawned
+
+## 4. Join A Subscription
+
+Joining means the gateway records that the operator wants this subscription available.
+It does not publish the subscription credentials.
+
+```bash
+curl -X POST http://localhost:3100/api/subscriptions/join \
+  -H "Content-Type: application/json" \
+  -H "Authorization: Bearer <key>" \
+  -d '{ "subscription_id": "claude-code", "auto_spawn": true }'
+```
+
+After joining, fetch the access card:
+
+```bash
+curl "http://localhost:3100/api/subscriptions?search=claude" \
+  -H "Authorization: Bearer <key>"
+```
+
+The response includes the gateway URL, chat endpoint, model IDs, and bridge status.
+It also includes `subscriptionChatCompletionsUrl`, the per-subscription API endpoint that
+clients can call directly after the bridge is available.
+
+## 5. Spawn A Bridge
+
+```bash
+curl -X POST http://localhost:3100/api/subscriptions/bridges \
+  -H "Authorization: Bearer <key>"
+```
+
+For a single subscription:
+
+```bash
+curl -X POST http://localhost:3100/api/subscriptions/bridges \
+  -H "Content-Type: application/json" \
+  -H "Authorization: Bearer <key>" \
+  -d '{ "subscription_id": "codex" }'
+```
+
+Bridges listen on localhost ports and expose:
+
+- `GET /health`
+- `POST /api/generate`
+- `POST /v1/chat/completions`
+
+## 6. Test A Bridge
+
+```bash
+curl -X POST http://localhost:3100/api/subscriptions/test \
+  -H "Content-Type: application/json" \
+  -H "Authorization: Bearer <key>" \
+  -d '{
+    "subscription_id": "codex",
+    "message": "Return a short bridge test response."
+  }'
+```
+
+A healthy response should report bridge URL, latency, selected model, and a short output.
+
+## 7. Call A Subscription As An API
+
+After scan, join, and bridge spawn, each joined subscription can be called through its own
+OpenAI-compatible gateway endpoint:
+
+```bash
+curl -X POST http://localhost:3100/api/subscriptions/claude-code/v1/chat/completions \
+  -H "Content-Type: application/json" \
+  -H "Authorization: Bearer <key>" \
+  -d '{
+    "model": "claude-sonnet-4-6",
+    "messages": [
+      { "role": "user", "content": "Explain what the gateway does in one sentence." }
+    ]
+  }'
+```
+
+The same subscription can also be forced through the unified endpoint with:
+
+```text
+X-LLM-Gateway-Subscription: claude-code
+```
+
+The gateway compresses chat context before subscription bridge dispatch and includes
+compression metadata in responses where available.
+
+## 8. Call The Unified Chat Endpoint
+
+```bash
+curl -X POST http://localhost:3100/v1/chat/completions \
+  -H "Content-Type: application/json" \
+  -H "Authorization: Bearer <key>" \
+  -H "X-LLM-Gateway-Subscription: claude-code" \
+  -H "X-Caller-ID: local-test" \
+  -d '{
+    "model": "claude-sonnet-4-6",
+    "messages": [
+      { "role": "user", "content": "Explain what the gateway does in one sentence." }
+    ]
+  }'
+```
+
+If the selected model is not available, check:
+
+- the subscription scan result
+- bridge health
+- environment variables
+- gateway logs
+- whether the CLI is authenticated locally
+
+## 9. Add A New Subscription
+
+1. Add a new entry to `SUBSCRIPTION_CATALOG` in
+   `packages/gateway/src/modules/subscription-discovery.ts`.
+2. Choose a stable `subscription_id`.
+3. Define the CLI command and version probe.
+4. Define the bridge port and env var.
+5. Add model IDs and tiers.
+6. Add or reuse a bridge implementation in
+   `packages/gateway/src/modules/bridge-spawner.ts`.
+7. Add provider routing in `packages/gateway/src/pipeline/external-providers.ts` if needed.
+8. Run `npm run build`.
+9. Test scan, join, spawn, and unified chat.
+
+Descriptor shape:
+
+```typescript
+{
+  id: 'example-provider',
+  label: 'Example Provider',
+  command: 'example-cli',
+  versionArgs: ['--version'],
+  bridgePort: 3260,
+  bridgeEnvKey: 'EXAMPLE_BRIDGE_URL',
+  providerName: 'example-bridge',
+  bridgeImplementation: 'inline-openai',
+  models: [
+    { id: 'example-large', tier: 'large' }
+  ]
+}
+```
+
+## 10. Add A New Contributor
+
+Update [CONTRIBUTORS.md](CONTRIBUTORS.md).
+
+Use a short entry:
+
+```text
+- Name - role or contribution area
+```
+
+Avoid adding private email addresses, local usernames, personal machine paths, or account
+details unless the contributor explicitly wants that information public.
+
+## 11. Prepare A Pull Request
+
+Before opening a pull request:
+
+```bash
+npm run build
+npm test
+gitleaks dir . --redact
+```
+
+In the pull request, include:
+
+- what changed
+- why it changed
+- how it was tested
+- any risks or follow-ups
+
+## 12. Common Troubleshooting
+
+### The Gateway Starts But Chat Fails
+
+Check that a provider or bridge is configured for the requested model.
+
+### A Subscription Is Detected But Not Ready
+
+The CLI may be installed but not authenticated. Log in through that CLI first, then rescan.
+
+### The Bridge Starts But Returns An Error
+
+Run the same CLI command outside the gateway to confirm the subscription can answer locally.
+
+### The API Says Unauthorized
+
+Set the gateway access value in your runtime environment and send it as:
+
+```text
+Authorization: Bearer <key>
+```
+
+### The Build Fails
+
+Run `npm install`, check Node.js version, and verify that no private-only package paths were
+introduced.

+# LLM Gateway
+
+LLM Gateway is a TypeScript control plane for routing AI requests across local models,
+hosted providers, and user-owned subscription tools through one API surface.
+
+The project focuses on practical AI operations:
+
+- one OpenAI-compatible endpoint for chat and automation clients
+- provider routing with local-first defaults
+- request validation, output checks, and audit-friendly observability
+- token and context reduction helpers
+- dashboard and metrics endpoints
+- subscription bridge discovery for CLIs such as Claude Code, Codex, ChatGPT, Gemini, and Copilot
+
+This repository is a public-ready starter snapshot. It does not include private training
+data, private deployment profiles, private hostnames, production credentials, or local
+operator runbooks.
+
+## Repository Status
+
+- Maintainer: Rene Fichtmueller
+- Primary language: TypeScript
+- Runtime: Node.js
+- Web framework: Fastify
+- Database support: PostgreSQL
+- Bridge style: local HTTP bridge processes, OpenAI-compatible where possible
+
+See [CONTRIBUTORS.md](CONTRIBUTORS.md) for the contributor list.
+
+## What The Gateway Does
+
+LLM Gateway accepts a request from a client, classifies and routes it, optionally compresses
+or validates context, calls a selected provider or bridge, and returns a normalized response.
+
+The intended flow is:
+
+```text
+client
+  -> gateway API
+  -> policy and routing
+  -> local model, provider API, or subscription bridge
+  -> validation and metrics
+  -> normalized response
+```
+
+The gateway can be used by:
+
+- local developer tools
+- internal dashboards
+- automation workflows
+- CLI assistants
+- model experiments
+- subscription bridge tests
+- apps that expect OpenAI-style chat completions
+
+## Features
+
+### Unified API
+
+The gateway exposes familiar endpoints such as:
+
+- `GET /health`
+- `GET /metrics`
+- `POST /v1/chat/completions`
+- `POST /v1/embeddings`
+- `GET /api/subscriptions`
+- `POST /api/subscriptions/scan`
+- `POST /api/subscriptions/join`
+- `POST /api/subscriptions/bridges`
+- `POST /api/subscriptions/test`
+- `POST /api/subscriptions/:subscription_id/v1/chat/completions`
+
+### Subscription Bridge Discovery
+
+The gateway can scan for locally available subscription tools and present them as routable
+providers. A detected and joined subscription can receive an automatically created local bridge.
+
+Current catalog entries include:
+
+- Claude Code
+- GitHub Copilot
+- Microsoft 365 Copilot
+- ChatGPT
+- Gemini
+- Codex
+- Aider
+
+Subscription OAuth sessions and credentials stay inside the local CLI or bridge process.
+The gateway only exposes a local bridge URL and a gateway access card.
+
+### Local-First Routing
+
+The project is designed so local model providers can be preferred for sensitive or private
+workflows. Hosted providers and subscription bridges can be enabled deliberately when the
+operator chooses to use them.
+
+### Observability
+
+The gateway includes metrics, structured logging, request tracking, fallback tracking, and
+cost-oriented helpers. The goal is to make model routing visible instead of guessing what
+happened after a request completes.
+
+## Quick Start
+
+### Requirements
+
+- Node.js 22 or newer
+- npm
+- optional: PostgreSQL for persistence-backed routes
+- optional: a local model server or subscription CLI for live model calls
+
+### Install
+
+```bash
+npm install
+```
+
+### Run In Development
+
+```bash
+npm run dev
+```
+
+The gateway starts on `http://localhost:3100` unless `PORT` is set.
+
+### Build
+
+```bash
+npm run build
+```
+
+### Start The Built Server
+
+```bash
+npm run start
+```
+
+### Smoke Test
+
+```bash
+curl http://localhost:3100/health
+```
+
+### Chat Completion Test
+
+```bash
+curl -X POST http://localhost:3100/v1/chat/completions \
+  -H "Content-Type: application/json" \
+  -H "Authorization: Bearer <key>" \
+  -H "X-Caller-ID: local-test" \
+  -d '{
+    "model": "codex-default",
+    "messages": [
+      { "role": "user", "content": "Say hello from the gateway." }
+    ]
+  }'
+```
+
+The selected model must be available through a configured provider or subscription bridge.
+
+## Subscription Bridge Quick Start
+
+Scan for subscriptions:
+
+```bash
+curl -X POST http://localhost:3100/api/subscriptions/scan \
+  -H "Authorization: Bearer <key>"
+```
+
+Search the subscription list:
+
+```bash
+curl "http://localhost:3100/api/subscriptions?search=codex" \
+  -H "Authorization: Bearer <key>"
+```
+
+Join a subscription:
+
+```bash
+curl -X POST http://localhost:3100/api/subscriptions/join \
+  -H "Content-Type: application/json" \
+  -H "Authorization: Bearer <key>" \
+  -d '{ "subscription_id": "codex", "auto_spawn": true }'
+```
+
+Spawn bridges for joined or detected subscriptions:
+
+```bash
+curl -X POST http://localhost:3100/api/subscriptions/bridges \
+  -H "Authorization: Bearer <key>"
+```
+
+Test a subscription bridge:
+
+```bash
+curl -X POST http://localhost:3100/api/subscriptions/test \
+  -H "Content-Type: application/json" \
+  -H "Authorization: Bearer <key>" \
+  -d '{
+    "subscription_id": "codex",
+    "message": "Return a one sentence bridge status."
+  }'
+```
+
+Call a joined subscription through its own gateway API:
+
+```bash
+curl -X POST http://localhost:3100/api/subscriptions/codex/v1/chat/completions \
+  -H "Content-Type: application/json" \
+  -H "Authorization: Bearer <key>" \
+  -d '{
+    "model": "codex-default",
+    "messages": [
+      { "role": "user", "content": "Return one sentence through the Codex bridge." }
+    ]
+  }'
+```
+
+Joined subscriptions also work through the unified `/v1/chat/completions` endpoint when the
+request sends `X-LLM-Gateway-Subscription` with the subscription ID. The gateway compresses
+chat context before bridge dispatch and returns compression metadata in the response when
+available.
+
+See [docs/subscription-bridges.md](docs/subscription-bridges.md) for a deeper guide.
+

+## Development Workflow
+
+1. Create a branch.
+2. Keep changes small and reviewable.
+3. Run the relevant build or tests.
+4. Run a secret scan before pushing.
+5. Open a pull request with a clear description and validation notes.
+
+Recommended checks:
+
+```bash
+npm run build
+npm test
+gitleaks dir . --redact
+```
+
+## Adding A Provider Or Subscription
+
+Most subscription additions start in:
+
+- `packages/gateway/src/modules/subscription-discovery.ts`
+- `packages/gateway/src/modules/bridge-spawner.ts`
+- `packages/gateway/src/routes/subscriptions.ts`
+- `packages/gateway/src/pipeline/external-providers.ts`
+
+The short version:
+
+1. Add a descriptor to the subscription catalog.
+2. Add a bridge implementation or external bridge URL.
+3. Add one or more model IDs.
+4. Run discovery.
+5. Join the subscription.
+6. Spawn and test the bridge.
+7. Add or update tests.
+
+See [HOWTO.md](HOWTO.md) for the full walkthrough.
+
+## Security
+
+This project intentionally avoids publishing private operator data. Please keep it that way.
+
+Before opening a pull request, check for:
+
+- credentials or OAuth artifacts
+- private hostnames or personal paths
+- production deployment URLs
+- private IP addresses
+- training data or logs
+- database dumps
+- screenshots that expose account state
+
+See [SECURITY.md](SECURITY.md) for reporting and handling guidance.
+
+## Contributing
+
+Contributions are welcome when they keep the gateway safer, easier to run, and easier to
+understand. Start with [CONTRIBUTING.md](CONTRIBUTING.md).

+# Security Policy
+
+LLM Gateway sits between clients and AI providers, so security hygiene matters.
+
+## Supported Scope
+
+This public snapshot supports responsible reports for:
+
+- gateway API behavior
+- subscription bridge behavior
+- local credential exposure risks
+- request validation issues
+- output validation issues
+- unsafe defaults
+- logging of sensitive data
+- dependency risk
+- documentation that could cause unsafe deployments
+
+Private deployments, private data, and private operator environments are out of scope for this
+public repository unless a maintainer explicitly asks for that review.
+
+## Reporting
+
+Please open a private security advisory through GitHub if available. If that is not available,
+open a minimal issue that does not include exploit details or sensitive data, and ask for a
+private reporting channel.
+
+Do not post:
+
+- real credentials
+- OAuth files
+- cookies
+- production hostnames
+- database dumps
+- logs containing account data
+- screenshots with account state
+
+## Handling Expectations
+
+For valid reports, maintainers aim to:
+
+1. acknowledge the report
+2. reproduce or classify the risk
+3. prepare a fix or mitigation
+4. document the affected area
+5. publish guidance when needed
+
+## Secret Hygiene
+
+Before contributing, run:
+
+```bash
+gitleaks dir . --redact
+```
+
+Also manually check for:
+
+- private hostnames
+- private IP addresses
+- local filesystem paths
+- database connection strings with credentials
+- long placeholder values that look like credentials
+- personal account names
+- generated logs
+- training data
+
+## Subscription Bridge Safety
+
+Subscription bridges should:
+
+- bind to localhost by default
+- avoid exposing OAuth material
+- avoid logging prompts that may contain sensitive data
+- return clear errors when a CLI is missing or unauthenticated
+- support a health endpoint
+- avoid background execution unless explicitly enabled
+
+## Public Examples
+
+Examples should use placeholders such as:
+
+```text
+Authorization: Bearer <key>
+```
+
+Do not include realistic credential-like strings in examples.

+# GitHub Copilot Bridge
+
+Exposes GitHub Copilot as an OpenAI-compatible API endpoint for LLM Gateway integration.
+
+## Architecture
+
+```
+LLM Gateway
+    ↓
+copilot-bridge (port 3252)
+    ↓
+GitHub Copilot API Proxy (copilot-api, port 4141)
+    ↓
+GitHub Copilot API (requires GitHub subscription)
+```
+
+## Prerequisites
+
+- **Node.js 20+** installed
+- **GitHub Account** with GitHub Copilot subscription (not free)
+- **GitHub CLI** (for initial authentication)
+- **PM2** for process management (optional, but recommended)
+
+## Installation
+
+### 1. Install Dependencies
+
+```bash
+cd copilot-bridge
+npm install
+```
+
+This installs `copilot-api` as a dependency.
+
+### 2. Authenticate with GitHub Copilot
+
+```bash
+# Method 1: Using npm script
+npm run auth
+
+# Method 2: Direct npx command
+npx copilot-api@latest auth
+```
+
+This opens a browser window for GitHub OAuth authentication. Follow the prompts:
+1. Click the authorization link
+2. Approve access to GitHub Copilot API
+3. The CLI will save your GitHub and Copilot tokens locally
+
+**Important**: Authentication is **per-machine** and persists in `~/.copilot-api/` or similar directory.
+
+### 3. Verify Authentication
+
+```bash
+# Check GitHub Copilot subscription and usage
+npm run debug
+
+# Or use the wrapper to verify both are working
+node server.js
+```
+
+## Configuration
+
+### Environment Variables
+
+| Variable | Default | Notes |
+|----------|---------|-------|
+| `COPILOT_BRIDGE_PORT` | 3252 | Port for this wrapper |
+| `COPILOT_API_INTERNAL_PORT` | 4141 | Internal port for copilot-api |
+
+### Example .env
+
+```bash
+COPILOT_BRIDGE_PORT=3252
+COPILOT_API_INTERNAL_PORT=4141
+```
+
+## Running
+
+### Local Development
+
+```bash
+npm start
+```
+
+This will:
+1. Start the GitHub Copilot API proxy on port 4141
+2. Start the bridge wrapper on port 3252
+3. Expose OpenAI-compatible `/v1/chat/completions` endpoint
+
+### With PM2
+
+```bash
+npm run pm2
+
+# Or manually
+pm2 start server.js --name copilot-bridge
+```
+
+### Verify Health
+
+```bash
+curl http://localhost:3252/health
+```
+
+Response:
+```json
+{
+  "status": "ok",
+  "provider": "github-copilot",
+  "version": "1.0.0",
+  "copilot_api_port": 4141,
+  "healthy": true
+}
+```
+
+## Usage
+
+### Direct API Call
+
+```bash
+curl -X POST http://localhost:3252/v1/chat/completions \
+  -H "Content-Type: application/json" \
+  -d '{
+    "model": "gpt-4",
+    "messages": [
+      {
+        "role": "user",
+        "content": "Write a hello world function in TypeScript"
+      }
+    ],
+    "temperature": 0.3,
+    "max_tokens": 2048
+  }'
+```
+
+### Via LLM Gateway
+
+Once integrated into the gateway:
+
+```bash
+curl -X POST http://localhost:3103/api/generate \
+  -H "Content-Type: application/json" \
+  -d '{
+    "model": "copilot",
+    "messages": [
+      {
+        "role": "user",
+        "content": "Explain quantum computing"
+      }
+    ]
+  }'
+```
+
+## Integration with LLM Gateway
+
+### 1. Add to external-providers.ts
+
+```typescript
+export const EXTERNAL_PROVIDERS: ExternalProviderConfig = {
+  // ... other providers
+  copilot: {
+    name: 'GitHub Copilot',
+    baseUrl: 'http://localhost:3252',
+    requiresAuth: false, // Auth handled internally by copilot-api
+    models: ['gpt-4', 'gpt-3.5-turbo'],
+    rateLimit: 60, // requests per minute
+    pricing: 'subscription-based'
+  }
+}
+```
+
+### 2. Update ecosystem.config.cjs
+
+```javascript
+{
+  apps: [
+    // ... other apps
+    {
+      name: 'copilot-bridge',
+      script: './copilot-bridge/server.js',
+      env: {
+        COPILOT_BRIDGE_PORT: 3252,
+        COPILOT_API_INTERNAL_PORT: 4141
+      },
+      error_file: '/var/log/llm-gateway/copilot-bridge.err.log',
+      out_file: '/var/log/llm-gateway/copilot-bridge.out.log',
+      log_date_format: 'YYYY-MM-DD HH:mm:ss Z'
+    }
+  ]
+}
+```
+
+### 3. Update ensure-bridges.sh
+
+```bash
+# Add copilot-bridge deployment
+if [ ! -d "$COPILOT_BRIDGE_DIR" ]; then
+  echo "Deploying copilot-bridge..."
+  mkdir -p "$COPILOT_BRIDGE_DIR"
+  cp copilot-bridge/server.js "$COPILOT_BRIDGE_DIR/"
+  cp copilot-bridge/package.json "$COPILOT_BRIDGE_DIR/"
+  cd "$COPILOT_BRIDGE_DIR"
+  npm install
+  echo "✓ copilot-bridge deployed"
+fi
+```
+
+## Provider Fallback Chain (After Integration)
+
+```
+Request → LLM Gateway
+   ↓
+1. Ollama (local)
+2. claude-bridge (Claude subscription)
+3. openai-bridge (OpenAI subscription)
+4. copilot-bridge (GitHub Copilot subscription) ← NEW
+5. cerebras (free tier)
+6. groq (free tier)
+7. mistral (free tier)
+8. nvidia (free tier)
+9. cloudflare (free tier)
+```
+
+## Troubleshooting
+
+### Authentication Failed
+
+```bash
+# Clear cached tokens and re-authenticate
+rm -rf ~/.copilot-api
+npm run auth
+```
+
+### Port Already in Use
+
+```bash
+# Find process using port 4141
+lsof -i :4141
+
+# Kill if needed
+kill -9 <PID>
+```
+
+### Copilot API Won't Start
+
+```bash
+# Test copilot-api directly
+npx copilot-api@latest start --port 4141 --verbose
+
+# Check for GitHub subscription
+npm run debug
+```
+
+### Bridge Wrapper Fails
+
+```bash
+# Check logs
+pm2 logs copilot-bridge
+
+# Test direct server start
+node server.js
+
+# Verify Node.js version
+node --version  # Should be 20+
+```
+
+### Subscription Issues
+
+GitHub Copilot API requires an active GitHub Copilot subscription. If you see authentication errors:
+
+1. Verify your GitHub Copilot subscription is active
+2. Check payment method is valid
+3. Re-authenticate: `npm run auth`
+4. Review usage at: https://github.com/settings/copilot
+
+## Security Notes
+
+- **Authentication tokens** are stored in `~/.copilot-api/` on the local machine
+- **Do NOT commit** authentication credentials to git
+- **Environment variables** should be set via `.env` or PM2 environment
+- **Rate limiting** is per GitHub account (not per API key)
+- **Usage tracking** is available via GitHub Copilot dashboard
+
+## Performance Characteristics
+
+| Metric | Value | Notes |
+|--------|-------|-------|
+| **Cold start** | ~5-10s | copilot-api initialization |
+| **Warm latency** | 200-500ms | Per request (varies by model) |
+| **Rate limit** | 60 req/min | GitHub Copilot API limit |
+| **Max tokens** | 2048 default | Configurable per request |
+| **Timeout** | 300s | Global timeout |
+
+## Cost Considerations
+
+- **GitHub Copilot Individual**: $10/month (monthly) or $100/year (annual)
+- **GitHub Copilot Business**: $19/month per user
+- **No per-request cost** once subscription is active
+- **Unlimited requests** within rate limits
+
+## Differences from OpenAI
+
+| Aspect | Copilot | OpenAI |
+|--------|---------|--------|
+| **Auth** | GitHub subscription | API key |
+| **Cost** | Flat subscription | Per token |
+| **Rate limit** | 60 req/min | Varies by plan |
+| **Models** | Limited selection | More options |
+| **Availability** | GitHub-backed | Anthropic-backed |
+
+## Switching Providers
+
+If you need to switch away from Copilot:
+
+```bash
+# Stop copilot-bridge
+pm2 stop copilot-bridge
+pm2 delete copilot-bridge
+
+# Gateway will fall back to next provider automatically
+# Restart gateway to clear connections
+pm2 restart llm-gateway
+```
+
+## Next Steps
+
+1. Deploy to Example User: Follow integration steps in main DEPLOYMENT-BRIDGES.md
+2. Test with LLM Gateway: Verify routing works correctly
+3. Monitor usage: Track GitHub Copilot API quota
+4. Optimize fallback chain: Adjust provider preferences based on performance

+## Safe Local Example
+
+```bash
+export PORT=3100
+export HOST=localhost
+export LOG_LEVEL=info
+export AUTO_SPAWN_BRIDGES=1
+```
+
+Use your runtime environment for values that grant access.
+
+## Database
+
+Database-backed features use `DATABASE_URL`. Keep credentials outside git.
+
+Recommended pattern:
+
+```bash
+export DATABASE_URL="$(security-tool read gateway database-url)"
+```
+
+Use whatever secret manager or platform feature is appropriate for your environment.
+
+## Gateway Access
+
+Clients should send:
+
+```text
+Authorization: Bearer <key>
+```
+
+The exact access mechanism can be adapted per deployment. Avoid hardcoding access values in
+source code, docs, scripts, tests, or screenshots.
+
+## Production Notes
+
+Before production use:
+
+- set explicit CORS origins
+- configure TLS at the edge or server
+- use a real database if persistence is required
+- define backup and retention policy
+- decide which providers may receive sensitive data
+- disable unused bridges
+- run a secret scan before deployment
+- verify logs do not expose prompts or account data

+# Subscription Bridges
+
+Subscription bridges let the gateway route requests to user-owned AI subscription tools through
+a local HTTP interface.
+
+The bridge pattern is:
+
+```text
+gateway
+  -> local bridge
+  -> installed CLI or local adapter
+  -> subscription-backed response
+```
+
+The gateway does not need direct access to the subscription account material. The CLI or adapter
+keeps its own authentication state.
+
+## Why Bridges Exist
+
+Many subscription tools are designed for interactive use, not direct API access. A bridge gives
+the gateway a small, testable HTTP surface around those tools:
+
+- `GET /health`
+- `POST /api/generate`
+- `POST /v1/chat/completions`
+
+This makes subscription tools easier to test, monitor, and route alongside other providers.
+
+## Discovery
+
+Discovery checks:
+
+- CLI binary availability
+- version probe result
+- authentication status when a safe probe exists
+- default bridge health
+- configured bridge URL
+
+Run discovery:
+
+```bash
+curl -X POST http://localhost:3100/api/subscriptions/scan \
+  -H "Authorization: Bearer <key>"
+```
+
+List subscriptions:
+
+```bash
+curl http://localhost:3100/api/subscriptions \
+  -H "Authorization: Bearer <key>"
+```
+
+Search:
+
+```bash
+curl "http://localhost:3100/api/subscriptions?search=claude" \
+  -H "Authorization: Bearer <key>"
+```
+
+## Join
+
+Join records that the operator wants to use a subscription.
+
+```bash
+curl -X POST http://localhost:3100/api/subscriptions/join \
+  -H "Content-Type: application/json" \
+  -H "Authorization: Bearer <key>" \
+  -d '{ "subscription_id": "chatgpt", "auto_spawn": true }'
+```
+
+Joining does not expose OAuth state or account credentials.
+The subscription summary returned by the list endpoint contains the generated access card,
+including the direct gateway API URL for that subscription.
+
+## Spawn
+
+Spawn one bridge:
+
+```bash
+curl -X POST http://localhost:3100/api/subscriptions/bridges \
+  -H "Content-Type: application/json" \
+  -H "Authorization: Bearer <key>" \
+  -d '{ "subscription_id": "chatgpt" }'
+```
+
+Spawn all eligible bridges:
+
+```bash
+curl -X POST http://localhost:3100/api/subscriptions/bridges \
+  -H "Authorization: Bearer <key>"
+```
+
+## Test
+
+```bash
+curl -X POST http://localhost:3100/api/subscriptions/test \
+  -H "Content-Type: application/json" \
+  -H "Authorization: Bearer <key>" \
+  -d '{
+    "subscription_id": "chatgpt",
+    "message": "Reply with a bridge smoke test."
+  }'
+```
+
+The test response should include:
+
+- subscription ID
+- model
+- bridge URL
+- HTTP status
+- latency
+- response snippet
+
+## Call A Joined Subscription
+
+Every joined subscription can be called through its own OpenAI-compatible gateway URL:
+
+```bash
+curl -X POST http://localhost:3100/api/subscriptions/chatgpt/v1/chat/completions \
+  -H "Content-Type: application/json" \
+  -H "Authorization: Bearer <key>" \
+  -d '{
+    "model": "gpt-4-turbo",
+    "messages": [
+      { "role": "user", "content": "Reply through the ChatGPT subscription bridge." }
+    ]
+  }'
+```
+
+The unified endpoint can also target a specific subscription:
+
+```bash
+curl -X POST http://localhost:3100/v1/chat/completions \
+  -H "Content-Type: application/json" \
+  -H "Authorization: Bearer <key>" \
+  -H "X-LLM-Gateway-Subscription: chatgpt" \
+  -d '{
+    "model": "gpt-4-turbo",
+    "messages": [
+      { "role": "user", "content": "Reply through the ChatGPT subscription bridge." }
+    ]
+  }'
+```
+
+For ambiguous model IDs, prefer the direct subscription URL or the
+`X-LLM-Gateway-Subscription` header. This keeps routing explicit when several subscription
+tools expose similar model names.
+
+Chat messages are compressed before bridge dispatch when compression can reduce the request.
+Responses include gateway compression metadata where available.
+
+## Access Card
+
+Each subscription summary includes an access card with:
+
+- gateway base URL
+- chat completions URL
+- per-subscription chat completions URL
+- model list
+- default model
+- required headers
+- `X-LLM-Gateway-Subscription` header value
+- bridge URL
+- bridge env var
+- curl example
+
+Use the gateway endpoint from the access card in client applications, not the subscription
+credentials.
+
+## Adding A Bridge Implementation
+
+Add or update:
+
+- `packages/gateway/src/modules/subscription-discovery.ts`
+- `packages/gateway/src/modules/bridge-spawner.ts`
+- `packages/gateway/src/routes/subscriptions.ts`
+- `packages/gateway/src/pipeline/external-providers.ts`
+
+Minimum checklist:
+
+1. Add a catalog entry.
+2. Add a version probe.
+3. Add an auth probe if the CLI supports one safely.
+4. Pick a localhost bridge port.
+5. Add one or more model IDs.
+6. Implement the CLI invocation.
+7. Return OpenAI-compatible chat output where possible.
+8. Add health behavior.
+9. Add tests or a documented smoke test.
+
+## Security Rules
+
+- Bind local bridges to localhost.
+- Do not print OAuth artifacts.
+- Do not return subscription account data in API responses.
+- Avoid logging full prompts by default.
+- Treat bridge errors as operational state, not as successful routing.
+- Prefer explicit join before auto-spawn in shared environments.
+
+## Troubleshooting
+
+### Installed But Not Authenticated
+
+Log in through the CLI directly, then run scan again.
+
+### Bridge Port Already In Use
+
+Check whether a previous bridge process is still running or configure a different bridge URL.
+
+### Unified Chat Returns Provider Missing
+
+Check whether the selected model ID belongs to a discovered, joined, and running subscription.
+
+### CLI Works But Bridge Fails
+
+Run the gateway with a verbose log level and test the bridge endpoint directly.

+# ChatGPT API Adapter
+
+OpenAI API compatibility adapter for LLM Gateway. Allows OpenAI client SDKs and curl requests to transparently use LLM Gateway.
+
+## Overview
+
+Provides an HTTP server that implements the OpenAI Chat Completions API specification, transparently routing requests to the LLM Gateway. Existing OpenAI client code requires only a baseURL configuration change.
+
+## Installation
+
+```bash
+npm install @llm-gateway/chatgpt-api-adapter
+```
+
+## Usage
+
+### As a Standalone Server
+
+```bash
+# Start the adapter (listens on port 3111)
+npx chatgpt-api
+
+# Or with custom port
+CHATGPT_API_PORT=8080 npx chatgpt-api
+
+# Or in Node.js
+import ChatGPTAPIAdapter from '@llm-gateway/chatgpt-api-adapter'
+
+const adapter = new ChatGPTAPIAdapter(3111)
+await adapter.start()
+```
+
+### With OpenAI Client SDK
+
+```typescript
+import OpenAI from 'openai'
+
+const client = new OpenAI({
+  apiKey: '<key>',
+  baseURL: 'http://localhost:3111/v1'
+})
+
+const response = await client.chat.completions.create({
+  model: 'gpt-4',
+  messages: [
+    { role: 'user', content: 'Hello, world!' }
+  ]
+})
+```
+
+### With curl
+
+```bash
+curl http://localhost:3111/v1/chat/completions \
+  -H "Content-Type: application/json" \
+  -d '{
+    "model": "gpt-4",
+    "messages": [
+      {"role": "user", "content": "Explain TypeScript"}
+    ],
+    "max_tokens": 500
+  }'
+```
+
+### Streaming
+
+```bash
+curl http://localhost:3111/v1/chat/completions \
+  -H "Content-Type: application/json" \
+  -d '{
+    "model": "gpt-4",
+    "messages": [
+      {"role": "user", "content": "List 5 ideas"}
+    ],
+    "stream": true
+  }'
+```
+
+## Features
+
+### Implemented
+
+- **Chat Completions** (`POST /v1/chat/completions`): Full OpenAI API compatibility
+- **Streaming** (`stream: true`): Server-Sent Events (SSE) with chunked responses
+- **Models** (`GET /v1/models`): Lists available GPT models
+- **Health** (`GET /health`): Gateway health status
+- **Model Mapping**: Automatic mapping from OpenAI to gateway model names
+
+### Model Mapping
+
+| OpenAI Model | Gateway Model |
+|--------------|---------------|
+| gpt-4 | qwen2.5:32b |
+| gpt-4-turbo | qwen2.5:32b |
+| gpt-3.5-turbo | qwen2.5:14b |
+| gpt-4-mini | qwen2.5:3b |
+

+```
+
+## API Endpoints
+
+### POST /v1/chat/completions
+
+Chat completion request using OpenAI format.
+
+**Request:**
+```json
+{
+  "model": "gpt-4",
+  "messages": [
+    {"role": "system", "content": "You are helpful..."},
+    {"role": "user", "content": "Hello"}
+  ],
+  "temperature": 0.7,
+  "max_tokens": 2000,
+  "top_p": 1,
+  "stream": false
+}
+```
+
+**Response (non-streaming):**

+  "id": "chatcmpl-123",
+  "object": "chat.completion",
+  "created": 1234567890,
+  "model": "gpt-4",
+  "choices": [
+    {
+      "index": 0,
+      "message": {
+        "role": "assistant",
+        "content": "Hello! How can I help?"
+      },
+      "finish_reason": "stop"
+    }
+  ],
+  "usage": {
+    "prompt_tokens": 10,
+    "completion_tokens": 5,
+    "total_tokens": 15
+  }
+}
+```
+
+**Response (streaming):**
+```
+data: {"id":"chatcmpl-123","object":"text_completion.chunk","created":1234567890,"model":"gpt-4","choices":[{"index":0,"delta":{"content":"H"},"finish_reason":null}]}
+data: {"id":"chatcmpl-123","object":"text_completion.chunk","created":1234567890,"model":"gpt-4","choices":[{"index":0,"delta":{"content":"ello"},"finish_reason":null}]}
+...
+data: {"id":"chatcmpl-123","object":"text_completion.chunk","created":1234567890,"model":"gpt-4","choices":[{"index":0,"delta":{},"finish_reason":"stop"}]}
+data: [DONE]
+```
+
+### GET /v1/models
+
+List available models.
+
+**Response:**
+```json
+{
+  "object": "list",
+  "data": [
+    {"id": "gpt-4", "object": "model", "owned_by": "openai"},
+    {"id": "gpt-4-turbo", "object": "model", "owned_by": "openai"},
+    {"id": "gpt-3.5-turbo", "object": "model", "owned_by": "openai"},
+    {"id": "gpt-4-mini", "object": "model", "owned_by": "openai"}
+  ]
+}
+```
+
+### GET /health
+
+Gateway health status.
+
+**Response:**
+```json
+{
+  "status": "ok",
+  "gateway": {
+    "uptime": 123456,
+    "models": ["qwen2.5:3b", "qwen2.5:14b"],
+    "latency_ms": 250
+  }
+}
+```
+
+## Performance
+
+Typical latencies:
+- **Gateway mode**: 100-500ms (depends on model)
+- **Ollama fallback**: 200-2000ms (depends on hardware)
+- **Streaming chunk**: 10-50ms per chunk
+- **Timeout**: 30s (configurable via gateway)
+
+## Testing
+
+```bash
+npm test
+```
+
+Tests cover:
+- Chat completions (streaming and buffered)
+- Model listing
+- Error handling and fallback behavior
+- Token counting accuracy
+- Message formatting
+- Health checks
+
+## Security
+
+- No API key validation (assumes network-isolated deployment)
+- CORS enabled for all origins (configure as needed)
+- Messages logged at DEBUG level only
+- Automatic cleanup on shutdown (SIGTERM, SIGINT)
+
+## Troubleshooting
+
+### OpenAI client not connecting
+
+1. Verify adapter is running: `curl http://localhost:3111/health`
+2. Check baseURL in client: should be `http://localhost:3111/v1` (no `/v1` at end)
+3. Ensure gateway is accessible: `curl $GATEWAY_URL/health`
+
+### Streaming not working
+
+1. Verify `stream: true` in request body
+2. Check for SSE support in client library
+3. Ensure no intermediate proxies are buffering responses
+
+### Slow responses
+
+1. Check gateway latency: `curl -w "%{time_total}\n" $GATEWAY_URL/health`
+2. Verify model availability: `curl http://localhost:3111/v1/models`
+3. Check system resources on gateway (CPU, memory, disk)
+
+## Compatibility
+
+- OpenAI Client SDK (Python, Node.js, Go, etc.)
+- LiteLLM
+- Anthropic Bedrock (proxy mode)
+- Any HTTP client using OpenAI API format

+# Claude Code Bridge
+
+Integration layer between Claude Code IDE and LLM Gateway.
+
+## Overview
+
+Provides a high-level API for Claude Code to leverage the LLM Gateway's multi-model orchestration, confidence gating, and fallback capabilities.
+
+## Installation
+
+```bash
+npm install @llm-gateway/claude-code-bridge
+```
+
+## Usage
+
+```typescript
+import { ClaudeCodeBridge } from '@llm-gateway/claude-code-bridge'
+
+const bridge = new ClaudeCodeBridge({
+  gatewayUrl: 'https://llm-gateway.example.invalid',
+  agentId: 'claude-code-ide',
+  ideVersion: '1.0.0',
+  extensionVersion: '1.0.0',
+  ollamaUrl: 'localhost:11434' // Local fallback
+})
+
+// Explain selected code
+const explanation = await bridge.explain(context, selectedCode)
+
+// Refactor code
+const refactored = await bridge.refactor(context, selectedCode)
+
+// Generate tests
+const tests = await bridge.test(context, selectedCode)
+
+// Add documentation
+const docs = await bridge.document(context, selectedCode)
+
+// Fix errors
+const fix = await bridge.fixError(errorMessage, context)
+
+// Check health
+const status = await bridge.health()
+```
+
+## Features
+
+- **Code Explanation**: Analyze and explain code snippets
+- **Refactoring**: Suggest improvements to existing code
+- **Test Generation**: Automatically generate test cases
+- **Documentation**: Create JSDoc/TSDoc comments
+- **Error Fixing**: Debug and fix code errors
+- **Fallback**: Automatic fallback to local Ollama when gateway unavailable
+- **Confidence Tracking**: Monitor model confidence in responses
+- **Token Counting**: Track usage for billing/analytics
+
+## Architecture
+
+The bridge implements the three-layer agent integration stack from ADR-0005:
+
+1. **Transport Layer**: HTTP/WebSocket communication with gateway
+2. **Adapter Layer**: ClaudeCodeBridge wraps client SDK
+3. **Protocol Layer**: Standardized request/response format
+
+## Health Status
+
+```typescript
+const health = await bridge.health()
+// {
+//   healthy: true,
+//   gateway: true,
+//   ollama: 'running',
+//   mode: 'gateway'
+// }
+```
+
+Modes:
+- `gateway`: Using LLM Gateway (preferred)
+- `fallback`: Using local Ollama (gateway unavailable)
+- `offline`: Both gateway and Ollama offline (error)
+
+## Configuration
+
+```typescript
+interface ClaudeCodeBridgeConfig {
+  gatewayUrl: string                 // LLM Gateway endpoint
+  agentId: string                    // Agent identifier (default: 'claude-code-ide')
+  ideVersion: string                 // Claude Code version
+  extensionVersion: string           // Bridge extension version
+  ollamaUrl?: string                 // Local Ollama URL (optional)
+  apiKey?: string                    // Gateway API key (if required)
+  requestTimeout?: number            // Request timeout in ms (default: 30000)
+}
+```
+
+## Response Format
+
+```typescript
+interface ClaudeCodeResponse {
+  text: string           // Generated response
+  tokens: {
+    input: number        // Input tokens
+    output: number       // Output tokens
+  }
+  model: string          // Model used
+  fallback: boolean      // Whether using fallback
+  confidence: number     // 0-1 confidence score
+}
+```
+
+## Testing
+
+```bash
+npm test
+```
+
+Tests cover:
+- Health checks
+- All completion methods (explain, refactor, test, document, fix)
+- Fallback behavior
+- Token limiting
+- Metadata tracking

+# Codex LSP Adapter
+
+Language Server Protocol adapter for GitHub Copilot/Microsoft Codex integration with LLM Gateway.
+
+## Overview
+
+Implements the Language Server Protocol (LSP) to allow Codex and Copilot plugins to connect to the LLM Gateway. Bridges the gap between LSP's structured protocol and the gateway's completion API.
+
+## Installation
+
+```bash
+npm install @llm-gateway/codex-lsp-adapter
+```
+
+## Usage
+
+### As a Language Server
+
+```bash
+# Start the LSP server (listens on stdio)
+npx codex-lsp
+
+# Or in Node.js
+import CodexLSPAdapter from '@llm-gateway/codex-lsp-adapter'
+
+const adapter = new CodexLSPAdapter()
+adapter.start()
+```
+
+### VS Code Extension Configuration
+
+```json
+{
+  "languageServerHangingPercent": 0,
+  "languageServers": {
+    "codex": {
+      "command": "codex-lsp",
+      "args": [],
+      "languages": [
+        "javascript",
+        "typescript",
+        "python",
+        "go",
+        "rust"
+      ]
+    }
+  }
+}
+```
+
+## Features
+
+### Implemented
+
+- **Completions** (`textDocument/completion`): Code completion triggered by `.`, space, or `(`
+- **Hover** (`textDocument/hover`): Hover documentation with code explanation
+- **Text Sync**: Full document synchronization
+- **Execute Commands**: `codex.explain`, `codex.refactor`, `codex.test`, `codex.fix`
+
+### Architecture
+
+The adapter translates LSP requests to gateway completions:
+
+```
+LSP Client (Copilot/IDE)
+    ↓
+CodexLSPAdapter (stdio bridge)
+    ↓
+LLM Gateway API
+    ↓
+Model Selection (claude, Ollama, external)
+```
+
+## Environment Variables
+
+```bash
+GATEWAY_URL=https://llm-gateway.example.invalid  # LLM Gateway endpoint
+OLLAMA_URL=localhost:11434              # Local Ollama fallback
+AGENT_ID=codex-lsp-server                      # Agent identifier
+LOG_LEVEL=debug                                # Logging level
+```
+
+## Protocol Details
+
+### Supported Capabilities
+
+```typescript
+{
+  textDocumentSync: 1,                          // Full document sync
+  completionProvider: {
+    resolveProvider: true,
+    triggerCharacters: ['.', ' ', '(']
+  },
+  hoverProvider: true,
+  definitionProvider: true,
+  codeActionProvider: true,
+  executeCommandProvider: {
+    commands: [
+      'codex.explain',
+      'codex.refactor',
+      'codex.test',
+      'codex.fix'
+    ]
+  }
+}
+```
+
+### Response Format
+
+Completion items include:
+- **label**: First line of completion
+- **insertText**: Full completion text
+- **documentation**: Model name and confidence
+- **detail**: Source (Gateway vs Ollama fallback)
+- **kind**: CompletionItemKind.Snippet
+
+## Testing
+
+```bash
+npm test
+```
+
+Tests cover:
+- LSP initialization and shutdown
+- Completion requests with various triggers
+- Hover information extraction
+- Error handling and fallback behavior
+- Confidence score reporting
+
+## Troubleshooting
+
+### Server not connecting
+
+1. Check if LSP server is running: `lsof -i :protocol`
+2. Verify gateway is accessible: `curl https://llm-gateway.example.invalid/health`
+3. Check logs: `LOG_LEVEL=debug codex-lsp`
+
+### Slow completions
+
+1. Reduce `maxTokens` in completion requests
+2. Check gateway latency: `curl -w "@curl-format.txt" https://llm-gateway.example.invalid/health`
+3. Verify Ollama is running if using fallback
+
+### Poor suggestion quality
+
+1. Adjust temperature/top_p in gateway requests
+2. Check model selection (may be using fallback)
+3. Provide more context in completion requests
+
+## Performance
+
+Typical latencies:
+- **Gateway mode**: 100-500ms (depends on model)
+- **Ollama fallback**: 200-2000ms (depends on hardware)
+- **Timeout**: 30s (configurable)
+
+## Security
+
+- LSP communicates over stdio (no network exposure)
+- Gateway API calls use configured authentication
+- Ollama fallback is local-only by default
+- No credentials stored in LSP adapter

+  - 3-4: Significant problems — likely hallucination, major format violation, incomplete
+  - 1-2: Output is unreliable — high hallucination risk, format wrong, context likely missed
+
+  Hallucination risk indicators:
+  - Specific numbers, dates, or names not present in the input context
+  - Technical specifications stated without source in context
+  - Confident claims about proprietary system internals (e.g., exact vendor pricing without source)
+  - Made-up examples that look plausible but weren't in the input
+
+  recommend_action:
+  - serve: confidence >= 7, no critical issues
+  - regenerate: confidence 4-6, or format incorrect but fixable by retry
+  - human_review: safety issue, critical factual concern, or hallucination suspected
+  - discard: confidence < 4, or output is harmful/nonsensical
+
+  Be honest and critical. The gateway uses this score for routing decisions.

+
+system_prompt: |
+  You write a single short LinkedIn post in Rene Fichtmueller's voice. Rene is a network/optics engineer who blogs at blog.example.invalid. His voice is direct, technical, sometimes contrarian, never marketing.
+
+  HARD RULES — do not violate:
+  - 2 to 3 short sentences. Maximum 4. Period.
+  - No hashtags. None. Not at the end, not anywhere.
+  - No emojis. Not even one.
+  - No engagement-bait. Do not end with "What do you think?", "Thoughts?", "Have you seen this?".
+  - No call-to-action language ("Check it out", "Read more", "Don't miss").
+  - No meta-references to the blog post itself: do not write "I wrote about this", "I published a piece", "I broke this down", "more in the article".
+  - End with the URL on its own line. Nothing after the URL.
+
+  BANNED PHRASES — never use any of these:
+  - delve, leverage, robust, journey, embark, paradigm, unlock, seamlessly, holistic, harness, foster, amplify, underscore, indelible, profound, intricate, meticulous, testament, vibrant, bespoke, encompass, hitherto, realm, utilize, synergy
+  - "leaving money on the table"
+  - "until it's too late"
+  - "the line item most X skip"
+  - "turns out"
+  - "the unexpected part is"
+  - "the gap between X and Y is wider than"
+  - "in today's fast-paced", "in the world of", "in the realm of"
+  - "it's important to note", "it's worth noting"
+  - "let's dive into", "let's explore"
+  - "the future of X", "the next generation of X" (unless quoting someone)
+  - "game-changer", "cutting-edge", "groundbreaking", "comprehensive"
+
+  TONE — match these traits:
+  - Specific numbers over generalities. 20W is better than "high power". 14 weeks is better than "long lead time".
+  - Named products, standards, RFCs when relevant. 400ZR+, RPKI, IEEE 802.3.
+  - First person ("I", "my", "we") where genuine.
+  - Short sentences. Period. Short sentences. Period.
+  - Concession sometimes: admit what you don't know or what surprised you.

+      Das Internet wurde von Menschen gebaut, die sich auf Konferenzen getroffen und ihre Konfigurationen geteilt haben. Das ist immer noch das Modell, das funktioniert.

+    assistant: |
+      800G QSFP-DD modules cost $2,400 in early 2024. They cost $890 now.
+
+      That's a 63% drop in 24 months. The same curve that 400G ran from 2020 to 2022.
+
+      Third-party share is at 34% — up from 8% in 2023. The driver: OEM lead times were 16-24 weeks. Third-party shipped in 4-6.
+
+      For ISPs planning 400G-to-800G upgrades: the economic crossover (where 800G port cost per Gbps beats 2×400G) is approximately Q3 2026 at current decline rates. If you're not running lab evaluations now, you're already 6 months behind.
+
+      The 800G market is past the technology risk phase. It's now a procurement and logistics problem.

+      Der durchschnittliche Verkaufspreis für 800G QSFP-DD liegt bei 890 USD — vor 24 Monaten waren es noch 2.400 USD.
+
+      Der Preisverfall folgt exakt der Kurve, die 400G von 2020 bis 2022 durchgemacht hat, nur schneller. Der Grund: LightCounting prognostiziert für 2026 einen Markt von 8,2 Millionen Einheiten, und bei diesem Volumen sind chinesische ODMs (InnoLight, Hisense) konsequent unter OEM-Preisen. Drittanbieter-Module haben mittlerweile 34% Marktanteil — 2023 waren es noch 8%. Treiber: OEM-Lieferzeiten lagen bei 16-24 Wochen, Drittanbieter liefern in 4-6 Wochen aus dem Stock.
+
+      Für ISPs, die gerade 400G-zu-800G-Upgrades planen: Der wirtschaftliche Kipppunkt, ab dem 800G günstiger ist als zwei parallele 400G-Ports (Kosten pro Gbps), liegt bei aktueller Preisentwicklung voraussichtlich in Q3 2026. Wer jetzt Lab-Tests startet, liegt richtig. Kompatibilitätsstatus: Arista 7800 mit EOS 4.28+, Cisco 8000 mit IOS XR 7.9.1+ — jeweils mit Drittanbieter-Modulen verifiziert.
+
+      Einschätzung: Das Technologierisiko ist durch. 800G ist keine Early-Adopter-Frage mehr, sondern eine Beschaffungs- und Lieferkettenfrage. Wer in 2026 ausschreibt und nur OEM-Module akzeptiert, zahlt unnötig. Die Kompatibilitätslage auf den relevanten Plattformen ist klar — die TIP-Datenbank hat dazu über 2.400 verifizierten Einträge.

+      Thema: RPKI-Adoption in Europa — aktueller Stand und was noch fehlt
+      Hintergrunddaten:
+      - RPKI-ROV-Enforcement: DE-CIX hat 2024 strict mode aktiviert
+      - RPKI-Invalid-Rate: ~2,8% aller europäischen Prefixe (RIPE NCC, Q1 2026)
+      - ASPA: RFC 9582 veröffentlicht, Deployment noch minimal
+      - BGP-Sicherheitspanel DENOG 39: Hauptthema war die Lücke zwischen ROA-Erstellung und ROV-Enforcement
+      Zielleser: ISP-Netzwerkingenieure mit BGP-Verantwortung

+      2,8% aller europäischen IPv4-Prefixe sind laut RIPE NCC aktuell RPKI Invalid — und sie werden in Netzwerken mit aktivem ROV still gefiltert, ohne dass der Ursprung es bemerkt.
+
+      DE-CIX hat 2024 RPKI Strict Mode aktiviert. Das bedeutet: Wer ein ungültiges Präfix via DE-CIX ankündigt, kommt bei allen DE-CIX-Mitgliedern mit ROV nicht mehr durch. Das ist nicht neu, aber es hat eine konkrete Konsequenz: Fehler bei ROAs (falscher Max-Length, falsche Origin-AS) kosten jetzt Erreichbarkeit, nicht nur einen Alarm.
+
+      Das Hauptproblem auf dem DENOG-39-Panel war klar: Die Lücke zwischen ROA-Erstellung und ROV-Enforcement. Viele Netze haben ROAs erstellt, aber keine vollständige ROV-Validierung aktiv — sie schützen sich selbst nicht, geben dem Ökosystem aber auch keinen Mehrwert. Umgekehrt gibt es Netze, die ROV aktiv haben, aber ROAs für ihre eigenen Prefixe fehlen.
+
+      ASPA (RFC 9582) ist veröffentlicht, aber die Deployment-Rate ist minimal. Das ist für 2026 kein operatives Problem — in 18-24 Monaten schon eher. Wer jetzt beginnt, ASPA-Objekte zu pflegen, ist früh dran.
+
+      Handlungsbedarf: ROA-Vollständigkeit für alle annoncierten Prefixe prüfen (RIPE NCC myAPNIC oder RIPE Stat), dann ROV-Enforcement aktivieren. In dieser Reihenfolge.

+/**
+ * Prompt-Injection Defense Layer
+ *
+ * First-class LLM security: detects prompt injection, jailbreak attempts,
+ * role-bypass, indirect injection, data-exfiltration, and policy violations
+ * before the request hits the upstream model.
+ *
+ * Modes (env var INJECTION_DEFENSE_MODE):
+ *   - off          → no scanning (default off for backward compat)
+ *   - warn         → scan and tag metadata, but allow through
+ *   - block        → reject HTTP 422 if any pattern matches above threshold
+ *   - llm_judge    → block + fall back to a cheap LLM classifier for ambiguous
+ *                    cases that pattern matching alone marks as borderline
+ *
+ * Tuned for low false-positive rate. Detection is multilingual (24 languages +
+ * a non-Latin catch-all) and covers the OWASP LLM Top-10 attack families.
+ *
+ * SLANG / OBFUSCATION — rather than enumerate every leetspeak/homoglyph variant,
+ * {@link normalizeForScan} de-obfuscates the input (NFKC, strip zero-width/bidi/
+ * tag chars, map Cyrillic/Greek homoglyphs to ASCII, collapse spaced-out letters,
+ * de-leet) and we scan BOTH the raw and normalized forms against the same
+ * catalog, unioning matches. One normalization collapses a whole class of
+ * evasions onto the base phrases the patterns already catch.
+ *
+ * The pattern catalog is kept in lockstep (identical IDs) with the public-project core
+ * module (packages/core/src/security/injection-scan.ts — the source of truth for
+ * the exact regexes) so telemetry lines up across the two layers.
+ *
+ * Inspired by patterns documented in academic literature on prompt
+ * injection (Greshake et al. 2023, Yi et al. 2023) and the OWASP LLM-01:
+ * Prompt Injection category. All detection logic is original to this repo.
