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.
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.
