 ### Fixes
 
 - Models/custom provider headers: propagate `models.providers.<name>.headers` across inline, fallback, and registry-found model resolution so header-authenticated proxies consistently receive configured request headers. (#27490) thanks @Sid-Qin.
+- Daemon/systemd install robustness: treat `systemctl --user is-enabled` exit-code-4 `not-found` responses as not-enabled by combining stderr/stdout detail parsing, so Ubuntu fresh installs no longer fail with `systemctl is-enabled unavailable`. (#33634) Thanks @Yuandiaodiaodiao.
 - Slack/system-event session routing: resolve reaction/member/pin/interaction system-event session keys through channel/account bindings (with sender-aware DM routing) so inbound Slack events target the correct agent session in multi-account setups instead of defaulting to `agent:main`. (#34045) Thanks @paulomcg, @daht-mad and @vincentkoc.
 - Gateway/HTTP tools invoke media compatibility: preserve raw media payload access for direct `/tools/invoke` clients by allowing media `nodes` invoke commands only in HTTP tool context, while keeping agent-context media invoke blocking to prevent base64 prompt bloat. (#34365) Thanks @obviyus.
 - Agents/Nodes media outputs: add dedicated `photos_latest` action handling, block media-returning `nodes invoke` commands, keep metadata-only `camera.list` invoke allowed, and normalize empty `photos_latest` results to a consistent response shape to prevent base64 context bloat. (#34332) Thanks @obviyus.
