On dual-stack LANs network-online.target is satisfied by the IPv6 SLAAC address about a second before DHCPv4 lands, so the first furtka-catalog-sync run died with 'Network is unreachable' and the next attempt was the daily timer (OnBootSec=10min + up to 6 h jitter). The state file stayed on 'checking' and the apps page showed 'checking…' with nothing running — first hardware bench, 2026-08-25. - furtka-catalog-sync.service: Restart=on-failure every 20 s, up to 8 times in 15 min - sync_catalog() writes stage 'error' + message on CatalogError, then re-raises (body moved to _sync_locked()) - apps page shows 'last sync failed: <error>' for that stage Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01MScAinbyMdeNc7H2BZdnnG

"""Tiny HTTP API + management UI for the Furtka resource manager.

|
|
Single stdlib http.server process, served behind Caddy (reverse-proxies
|
|
/apps, /api, /login and /logout from :80 to here).
|
|
|
|
Security: single-admin password login, cookie-session, werkzeug-hashed
|
|
password stored at /var/lib/furtka/users.json (0600). Sessions live in
|
|
memory — `systemctl restart furtka-api` invalidates everyone. Fresh

|
installs pre-populate users.json from the webinstaller step-1 password;
|
|
upgrades from pre-auth releases fall into a first-run setup form at
|
|
/login where the admin password is created from the browser. Authentik
|
|
integration remains the long-term plan; this is the pragmatic alpha

stopgap.
