Struct BrainState 

pub struct BrainState {
    pub profiles: HashMap<String, ProfileRecord>,
    pub balanced_recall: BalancedRecallState,
    pub bindings: Vec<ProfileBinding>,
}

Runtime brain state — profile registry + active state per profile.

ADR-032 §1: BrainState holds profile registry and lifecycle metadata. Posteriors live inside each profile’s own state, opaque to brain.

Fields

profiles: HashMap<String, ProfileRecord>

Registered profiles indexed by profile_id.

balanced_recall: BalancedRecallState

In-memory BalancedRecallState for the active default profile.

bindings: Vec<ProfileBinding>

Profile binding table — maps (actor, namespace, consumer_kind) → profile_id.

Implementations

impl BrainState

pub fn new(entity_capacity: usize) -> Self

pub fn to_snapshot(&self) -> BrainStateSnapshot

pub fn from_snapshot( snapshot: BrainStateSnapshot, entity_capacity: usize, ) -> Self

pub fn reset_posteriors(&mut self)

Reset the balanced-recall profile posteriors to priors.

pub fn resolve( &self, actor: Option<&str>, namespace: Option<&str>, consumer_kind: &str, ) -> Option<&ProfileRecord>

Resolve a profile_id for the given caller context (ADR-032 §10).

Longest-match wins: actor + namespace + consumer_kind beats actor + consumer_kind beats namespace + consumer_kind beats consumer_kind alone. Returns the balanced-recall-v1 default when no explicit binding matches.
