Root cause: 9router combo models (deepseek-v4-flash-free on fallback) have TTFT up to 30-40s. Caddy 9router route inherited the default response_header_timeout 30s / read_timeout 60s → 504 'timeout awaiting response headers' even though 9router was still processing. Cloudflare/log showed repeated 504s; health watchdog (correctly) flagged the outage. Fixes: 1. Caddy: dedicated 9router route with response_header_timeout 120s + read/write 300s (was default 30/60). Removed invalid top-level flush_interval on upload block that broke caddy reload (2.11 rejects it as transport subdirective). 2. health-check: HTTP timeout 60→150s (mirror Caddy), and alert ONLY when EVERY model fails — any working model means the server's fallback chain succeeds. Early-exit on first success to bound runtime (~3s healthy). Verified: 3 runs green, ~3.6s each, silent exit 0.
