# #25723 runtime transcripts

## Before: unchanged handler (fs-32 T3 server; same handler as main daa720a986)
1. delegate_task target {providerInstanceId: claudeAgent, model: claude-issue-25723-unadvertised}
   -> {"_tag":"OrchestratorMcpFailure","code":"model_unavailable","message":"Model claude-issue-25723-unadvertised is not advertised by provider claudeAgent."}
2. delegate_task target {claudeAgent, claude-haiku-5-5}, mode wait -> child completed, summary "OK"
3. t3_thread_configure(<delegated child>, {instanceId: claudeAgent, model: claude-issue-25723-unadvertised}) -> {"sequence":220042}
   t3_thread_configuration(<delegated child>) -> modelSelection {"instanceId":"claudeAgent","model":"claude-issue-25723-unadvertised"}
4. variant: t3_thread_configure(<delegated child>, {instanceId: codex, model: claude-opus-5-5}) -> {"sequence":220073}
   t3_thread_configuration(<delegated child>) -> modelSelection {"instanceId":"codex","model":"claude-opus-5-5"}
5. control: t3_thread_configure(<delegated child>, {instanceId: claudeAgent, model: claude-haiku-5-5}) -> {"sequence":220091} (advertised; accepted, restores probe)

## After: fix/issue-25723 at d287732bd9, fresh dev server (T3CODE_DEV_SEED=0), driver mcp.py over /mcp
