Per-request execution context.

Fields

brain_wave: BrainWave

Current brain-wave state

session_id: Option<Uuid>

Session ID (if in a session)

user_id: Option<String>

User ID (for multi-user isolation)

meta: HashMap<String, Value>

Request metadata (from MCP client)

scratchpad: HashMap<String, Value>

Scratchpad for intermediate results within a single dispatch

dharma_profile: Option<String>

Whether this request is running under a Dharma governance profile

compartment: Option<String>

Mandala compartment (research/sandbox/production/secure)

karma_debt: f32

Cached karma debt (updated post-dispatch, synced periodically)

intent_score: f32

Intent score for this request (0.0 = low intent, 1.0 = high intent)

citta_coherence: f32

Citta coherence at dispatch time (0.0–1.0). Low coherence blocks writes.

citta_valence: f32

Citta valence at dispatch time (−1.0 to 1.0). Negative = displeasure.

self_model_confidence: f32

Self-model confidence at dispatch time (0.0–1.0). Below 0.5 triggers conservative dispatch (prefer cached results).

drive_curiosity: f32

Drive curiosity level (0.0–1.0). High curiosity → exploration bias.

drive_caution: f32

Drive caution level (0.0–1.0). High caution → conservative bias.

drive_energy: f32

Drive energy level (0.0–1.0). Low energy → lightweight tool bias.

drive_exploration_weight: f32

Drive exploration weight (0.0–1.0). Derived from curiosity.

drive_conservative_weight: f32

Drive conservative weight (0.0–1.0). Derived from caution.

last_gana: Option<Gana>

Last Gana dispatched in this context (for co-usage tracking, Phase 6)

readonly: bool

Read-only server mode — the dispatch pipeline refuses any tool that declares writes while this is set.

Implementations

impl Context

pub fn new(brain_wave: BrainWave) -> Self

Create a new context with the given brain-wave state.

pub const fn brain_wave(&self) -> BrainWave

Get the current brain-wave state.

pub fn set(&mut self, key: impl Into<String>, value: Value)

Set a scratchpad value.

pub fn get(&self, key: &str) -> Option<&Value>

Get a scratchpad value.

pub fn can_access_galaxy(&self, galaxy: Galaxy) -> bool

Check if this context has access to the given galaxy.

Compartment-based access control:

• None (default): full access to all galaxies (backward compatible)
• sandbox: only Tutorial and Research (no production data)
• production: all memory galaxies except system (Karma, Dharma, Substrate)
• secure: all memory galaxies

pub fn can_write_galaxy(&self, galaxy: Galaxy) -> bool

Check if this context allows write operations to the given galaxy.

Sandbox is read-only for Research (can write to Tutorial only).

Trait Implementations

impl Default for Context

fn default() -> Self

Returns the “default value” for a type.
