The LLM Gateway is configured to run on port 3103 in ecosystem.config.cjs,
but the Cloudflare tunnel configuration and setup script were referencing port
3100, causing 502 Bad Gateway errors.
Updates:
- cloudflare-tunnel.md: Changed tunnel ingress from localhost:3100 to localhost:3103
- setup-erik.sh: Updated health check URL and output messages to port 3103
- This fixes the Cloudflare tunnel connection that was causing public HTTPS access to fail

The learning process was failing to communicate with the gateway because:
1. Gateway was sending 'Strict-Transport-Security' header on HTTP responses
2. Node.js fetch respects HSTS and upgrades subsequent requests to HTTPS
3. Gateway only has HTTP listener (localhost:3103), no HTTPS
4. Result: SSL 'packet length too long' error on second request attempt
Solution: Modified registerHSTSMiddleware to only send HSTS header when
the connection is already secure (HTTPS or x-forwarded-proto: https).
HTTP connections will not get the HSTS header, preventing the forced upgrade.
- Add openai-bridge service (port 3251) for ChatGPT and Codex integration
- Update external-providers.ts with openai and chatgpt provider definitions
- Add GPT-4 Turbo, GPT-4, and GPT-3.5 Turbo models to provider registry
- Modify getApiKey() to handle bridge provider authentication
- Modify getBaseUrl() to construct URLs from env vars
- Update ecosystem.config.cjs with OPENAI_BRIDGE_URL and OPENAI_API_KEY config
- Add openai-bridge PM2 service configuration (port 3251)
- Support both claude-bridge (port 3250) and openai-bridge (port 3251) as subscription services
- Extend fallback chain: claude → openai/chatgpt → cerebras → groq → mistral → nvidia → cloudflare

New package @llm-gateway/ctx-health (packages/ctx-health/) — a TypeScript
infrastructure monitoring and auto-healing daemon. Monitors 8 subsystems
every 60s (PM2, PostgreSQL, Ollama, Cloudflare tunnel, disk, memory,
network, WireGuard), gets AI-powered root cause analysis via the gateway
(ctxhealer caller / ctx_health_diagnose task_type), executes healing
actions with cooldown (5min) and escalation guards (3+ failures → human
escalation), persists all incidents to ctx_health_incidents and
ctx_health_status tables. Dry-run mode via CTX_HEALTH_DRY_RUN=true.
Runs as ctx-health PM2 process on Erik server.
