Struct PresenceFabric 

pub struct PresenceFabric { /* private fields */ }

Presence Fabric manages presence states for all Resonators

Key insight: Presence is multidimensional, not binary. A Resonator can be:

• Discoverable but not responsive
• Responsive but not accepting new couplings
• Present but in silent mode

Implementations

impl PresenceFabric

pub fn new(config: &PresenceFabricConfig) -> Self

pub async fn initialize_presence( &self, resonator: &ResonatorId, config: &PresenceConfig, ) -> Result<(), String>

Initialize presence for a new Resonator

pub async fn signal_presence( &self, resonator: ResonatorId, state: PresenceState, ) -> Result<(), PresenceError>

Signal presence (MUST be low-cost and non-intrusive)

ARCHITECTURAL RULE: Presence signaling must not be burdensome.

pub async fn enable_silent_presence(&self, resonator: ResonatorId)

Enable silent presence (existence without active signaling)

This is important: a Resonator may be present without actively participating. Presence does NOT imply willingness to interact.

pub async fn disable_silent_presence(&self, resonator: ResonatorId)

Disable silent mode

pub fn get_presence(&self, resonator: &ResonatorId) -> Option<PresenceState>

Get presence state

pub fn is_present(&self, resonator: &ResonatorId) -> bool

Check if Resonator is present

pub async fn update_presence_gradient( &self, resonator: &ResonatorId, adjustment: PresenceAdjustment, )

Update presence gradient (called periodically to adjust presence based on behavior)

pub async fn restore_presence( &self, resonator: &ResonatorId, state: &PresenceState, ) -> Result<(), String>

Restore presence from continuity record

pub fn remove_presence(&self, resonator: &ResonatorId)

Remove presence (for cleanup)

pub fn get_all_present(&self) -> Vec<ResonatorId>

Get all present Resonators

pub fn count(&self) -> usize

Count of present Resonators
