Root cause: PluginHookAgentContext in before_model_resolve only has
agentId, sessionKey, sessionId, workspaceDir, messageProvider.
senderId, channelId, input are NOT available in this hook phase.
The plugin was reading ctx.senderId (undefined) -> inHumanList=false
for ALL Discord sessions -> shouldUseNoReply=true -> all silenced.
Fix: use event.prompt which contains the full user message including
the 'Conversation info (untrusted metadata)' JSON block, and extract
sender_id from there. Same fix applied to before_prompt_build.
Root cause: installer called 'openclaw gateway restart' (async via systemd)
then immediately validated model visibility — race condition caused validation
to fail and rollback the correct config.
Fix: remove restart + validation from script entirely. Script only writes config.
User restarts gateway manually after install completes.
Also fix CONFIG.example.json: contextWindow 4096->200000, maxTokens 64->8192
(OpenClaw requires minimum 16000 contextWindow).
