Panel agents answer the user prompt in parallel (read-only, non-streaming);
their responses are merged into the worker's last user message as a
<panel_responses> block, and the session agent synthesizes one final
streamed answer. The RunPanel engine is built layer-ready for future MoA.
- New session fields: multi_model_mode (off/fusion), panel_agent_ids (CSV)
with idempotent column migration
- New partial Services/AnthropicService.Panel.cs holding the RunPanel engine
- Provider-agnostic members: Anthropic RunNonStreamingToolLoop / OpenAI
CompleteText / CLI plan-mode; all forced read-only, persisted with Tag=panel
- SSE events: panel_start, panel_member_start, panel_member_done, panel_done
- Frontend: multi-agent picker, live panel bubbles, history rendering
- Graceful degradation: panel errors fall back to worker-only

Opus 4.5+ and Sonnet 4.6+ support a new "effort" knob that controls how
much budget the model spends on thinking and tool calls. Plumb it through
end to end so each agent can pick its own level.
Storage & shape:
- New TEXT column agents.effort (default '') added via TryAddColumn.
- AgentRecord.Effort + INSERT/UPDATE in DatabaseService.Agents.cs.
- ChatContext.Effort + SubAgentContext.Effort so the value travels with the
request alongside model and tool settings.
Agent editor:
- Effort dropdown above git-commit behavior in the agent form (low/medium/
high/xhigh/max plus empty = "use default"). Always visible; on OpenAI
providers the value is sent but silently ignored.
- agent-page.js load/save and AgentEndpoint create/update wired up.
Anthropic API path:
- StreamChat and RunNonStreamingToolLoop add output_config: { effort } when
effort is set and not "high" – empty/null/"high" means "omit and let the
API pick its default".
- Sub-agents (preparer/review/finalizer) get the parameter through
RunAgentChat so each step uses its own agent's effort.
Anthropic CLI path:
- ClaudeCliService.ChatStreamingAsync takes an effort parameter and exports
CLAUDE_CODE_EFFORT_LEVEL on the spawned process. Env-var beats the
--effort flag because it also covers "max" and "ultracode".
- StreamChatViaCli, ChatNonStreamingViaCli, RunSubAgentViaCli, and the
ChatEndpoint anthropic branches all hand the value through.
ARCHITECTURE.md / ARCHITECTURE_QUICK.md updated with the new field.

Anthropic hat Anfang März 2026 die Default-Cache-TTL stillschweigend
von 1h auf 5min gesenkt. Bei Sessions mit Pausen >5min wird der Cache
jedes Mal neu geschrieben (teuer). Dieser Commit aktiviert die
extended 1h-TTL über beide Pfade.
API-Pfad (AnthropicService):
- Beta-Header "extended-cache-ttl-2025-04-11" hinzugefügt
- Falsches Top-Level cache_control (Root-Level wurde ignoriert) entfernt
- Neue Helper ApplyCacheControlToLast() setzt cache_control idempotent
auf das letzte Element via JSON-Roundtrip zu Dictionary
- 2 Cache-Breakpoints pro Iteration:
* Letztes Tool (cached gesamten Tool-Block)
* Letzter System-Prompt-Block (cached System-Prompt)
- Sub-Agent-Loop (Preparer/Review/Finalizer): String-System-Prompt wird
bei Bedarf in Block-Form mit cache_control konvertiert
CLI-Pfad (ClaudeCliService):
- Env-Var ENABLE_PROMPT_CACHING_1H=1 für jeden CLI-Child-Prozess gesetzt
(offizieller Opt-in seit Claude CLI 2.1.108, gilt für API-Key,
Bedrock, Vertex, Foundry)
Statt Hard-Error "Kein API-Key zugewiesen" nutzen Sub-Agents jetzt
Claude CLI als Fallback. Preparer wird nur übersprungen wenn weder
Key noch CLI verfügbar sind.
