Bundle the remaining imaging hardening and the host/CI fixes from the
"Doe alles" pass into one release.
Furniture:
- Resolve the local bundle extension from FURNI_BUNDLE_EXT (".hab" default,
".nitro" for a stock Nitro client). The configured extension is written by
imports/repairs and preferred on lookup; the other stays a legacy fallback.
Imaging:
- Avatar proxy sends s-maxage=86400 + stale-while-revalidate (300/3600 for the
fallback path) so the edge can hold a render a day.
- Cloudflare cache rule now covers /api/imaging/ (verified MISS->HIT live).
- Document that bare /imaging is shadowed by the edge proxy to the renderer.
Ops/CI:
- docker-update.sh skips a CI-managed host (exit 0) instead of failing cron.
- ci-deploy.sh runs the cross-browser imaging gate (chromium+firefox+webkit)
against the candidate before cutover; DEPLOY_SKIP_CROSS_BROWSER=1 as escape.
- scripts/imager-health-alert.sh alerts (Discord) on imager up/down transitions;
runs from cron every 5 minutes.
Tests:
- Furniture bundle-ext resolver + FURNI_BUNDLE_EXT wiring.
- Imaging performance budget (bytes + warm latency).
- classifyDdos: /api/imaging/* stays in the api bucket.

# Alert when the local avatar imager stops rendering, and again when it recovers.
|
|
#
|
|
# Intended to run from cron every few minutes (see `crontab -l`). Steady-state is
|
|
# silent; a state change posts to DISCORD_WEBHOOK_URL (from the environment or
|
|
# .env). While the imager stays down it re-alerts at most once per
|
|
# HEALTH_ALERT_COOLDOWN_MIN. The script always exits 0 so an outage never turns
|
|
# into a noisy cron failure; the alert itself (and this log) is the signal.
