-# KNELPerf -> Grav publisher — pushes perf intel to performance.knownelement.com.
+# KNELPerf -> KNELPerfHub publisher.
 #
-# Grav (Cloudron app 8336f951) pages are markdown files; we write them
-# directly via ssh -> docker exec into /app/data/user/pages/, then clear
-# cache. Auth to the SITE is Cloudron SSO (org-restricted); publishing is
-# file-based, no web login needed.
+# Architecture ruling (founder, 2026-09-06): NO server-side tooling runs in
+# the Grav container. This script renders pages as markdown into the
+# KNELPerfHub git repo and PUSHES; the Cloudron VPS's ukrrs-hub-pull.timer
+# git-pulls that repo into the Grav pages dir every 5 min (Grav
+# cache.check=file picks changes up). Scraping/collectors run on the
+# tooling hosts, not in the app container.
 #
-# What gets published (idempotent, safe to run from cron/automation):
-#   performance/            home dashboard (latest risk brief + arbitrage
-#                           verdict + baseline index + fleet table)
-#   performance/reports/*   the three repo reports (AMT, desktop, scheduler)
-#   performance/baselines/  per-host latest baseline summary tables
-# Env: GRAV_APP_ID (default below), GRAV_HOST (ssh host, default VPS tailnet)
+# Env: HUB_REPO (default below), SOLAR_REPO.
