researchclaw-hybrid-llm-opus-for-8-critical-stages-haiku-for-15

AutoResearchClaw’s 23 pipeline stages split cleanly: 8 critical reasoning stages (hypothesis generation, paper writing, peer review — stages 2, 7, 8, 9, 14, 15, 17, 18) require Opus 4.6 via ACP; 15 routine stages (topic init, resource planning, export, status) use Haiku 4.5. AutoResearchClaw natively supports primary + fallback model config. Stay within Anthropic ecosystem (Haiku 4.5) rather than GPT-4o-mini to avoid external API dependencies.
