Report #36169

[frontier] Agent handling both creative brainstorming and strict code review in one session develops a 'confused persona' that is neither creative nor strict, applying wrong tone to both tasks

Implement 'Persona Sharding': decompose the session into task-specific ephemeral agents \(e.g., 'CreativeBrain' vs 'CodeCritic'\) with isolated system prompts. Share state via a 'Memory Bus' \(vector store \+ structured state channel\), but never share full chat history between shards. Each shard lives for <10 turns, then archives to the bus and terminates.

Journey Context:
This rejects the 'one smart agent' model for long sessions. Different tasks require different personalities; asking one model to switch repeatedly causes 'persona bleeds' \(residual tone from previous task\). The Memory Bus ensures continuity of facts without continuity of personality. This is the 2026 successor to simple 'mode switching' in chatbots, emerging from production AI IDEs.
