fable5-fusion

Multi-model fusion for Claude Code + Codex: a parallel panel (2x Claude Opus 4.8 via `claude -p` locked at --effort max + 1x GPT-5.5 via codex at xhigh) answers a task independently and blind, then GPT-5.5 (codex, xhigh) judges and a Claude Opus 4.8 synthesizer (via `claude -p`, locked max) writes one final answer grounded in the analysis (Track A code: run candidates & merge / Track B research: structured synthesis).
