Struct PersonaManager 

pub struct PersonaManager { /* private fields */ }

Manages persona lifecycle and coordinates persona-aware execution.

Implementations

impl PersonaManager

pub fn new() -> Self

Creates a new persona manager with default personas.

pub fn with_defaults(personas: Vec<Persona>) -> Self

Creates a new persona manager, optionally loading from existing data.

pub fn get_active_persona(&self) -> Option<Persona>

Returns the current active persona, if any.

pub fn set_active_persona(&self, id: &str) -> Result<()>

Sets the active persona by ID.

pub fn active_system_prompt(&self) -> String

Returns the system prompt for the active persona. Falls back to a default prompt if no active persona.

pub fn create_default_personas(&self)

Creates the three default personas (Dev, Review, Research).

pub fn first_enabled(&self) -> Option<Persona>

Returns the first enabled persona, for wiring into OuroborosEngine.

pub fn store(&self) -> &PersonaStore

Returns the persona store for direct access.

pub fn active_persona_id(&self) -> Option<String>

Returns the ID of the active persona.

pub fn apply_config(&self, cfg: &PersonaConfig)

Active persona 의 우선순위 결정:

1. StateStore index.json 의 active_persona_id (enabled 면 적용)
2. PersonaConfig.default_persona_id (enabled 면 적용)
3. store 의 첫 번째 enabled
4. None

&self — Arc<PersonaManager> 뒤에서 호출됨.

pub async fn load_from_state_store(&self, store: &StateStore) -> Result<()>

StateStore 에서 페르소나 + active_persona_id 를 로드. 손상·부재 시 silent fallback 하지 않고 Result::Err 로 전파. 호출자는 defaults 가 이미 new() 로 박혀 있음을 알고 있어야 함.

pub async fn persist(&self, store: &StateStore) -> Result<()>

StateStore 에 페르소나 + active_persona_id 를 저장. 메모리 상태는 유지, IO 실패는 Result 로 전파.

pub async fn set_active( &self, id: &str, store: Option<&StateStore>, ) -> Result<Option<String>>

글로벌 활성 페르소나 변경. 성공 시 슬롯 변경 + StateStore flush. 새 system_prompt 를 Ok(Some(prompt)) 로 반환 — 호출자가 IntentEngine::set_persona_prompt 로 직접 재시드 (kernel ↔ ouroboros 의존성 방향 회피).

&self — interior mutability (Arc 뒤 호출 가능).
