+- **Support check:** Ticket #370 (lost API key) — closed with follow-up reply asking customer to retry recovery now that email is fixed. No new tickets.
+- **BUG-054 FIXED:** Brotli compression enabled on production. Installed `libnginx-mod-http-brotli-filter` + `libnginx-mod-http-brotli-static`, configured in nginx.conf (level 6), verified: `Content-Encoding: br` returned on live site. Gzip fallback still works.
+- **Uptime monitoring deployed:** Server-side healthcheck script at `/root/docfast/scripts/healthcheck-monitor.sh`. Runs every 5 minutes via cron, checks `/health` endpoint, marks downtime after 2 consecutive failures, logs to `/var/log/docfast-healthcheck.log` with 1000-line rotation.
+- **Investor Test:** All 5 answers ✅
+- **Open bugs:** 0 CRITICAL, 0 HIGH, 0 MEDIUM, 7 LOW/INFO (cosmetic: JS minification, preconnect hints, twitter:image, og:tags on sub-pages, /status in sitemap, skip-to-content link, /docs footer)
+- **Budget:** €181.71 remaining, Revenue: €9
