Struct CoherenceField 

pub struct CoherenceField<V: SensorVocabulary<N>, const N: usize> { /* private fields */ }

The coherence field: a map of context → CoherenceAccumulator.

Generic over any sensor vocabulary V implementing SensorVocabulary<N>. Maintains at most [MAX_CONTEXTS] entries with LRU eviction.

Patent Claims 6–7, 13.

Implementations

impl<V: SensorVocabulary<N>, const N: usize> CoherenceField<V, N>

pub fn new() -> Self

Construct a fresh field with no accumulated coherence.

pub fn effective_coherence(&self, instant: f32, key: &ContextKey<V, N>) -> f32

Compute effective coherence using the asymmetric gate (CCF-001).

• Unfamiliar (ctx < 0.3): min(instant, ctx) — earn trust first.
• Familiar (ctx ≥ 0.3): 0.3 × instant + 0.7 × ctx — history buffers noise.

pub fn positive_interaction( &mut self, key: &ContextKey<V, N>, personality: &Personality, tick: u64, alone: bool, )

Record a positive interaction for a context, modulated by personality.

Creates the accumulator at the personality baseline if the context is unseen.

pub fn negative_interaction( &mut self, key: &ContextKey<V, N>, personality: &Personality, tick: u64, )

Record a negative interaction for a context, modulated by personality.

Creates the accumulator at the personality baseline if the context is unseen.

pub fn context_coherence(&self, key: &ContextKey<V, N>) -> f32

Get the accumulated coherence for a context.

Returns the accumulator value if seen, or the fallback / 0.0 for unseen contexts.

pub fn context_interaction_count(&self, key: &ContextKey<V, N>) -> u32

Number of positive interactions recorded for a context (0 if unseen).

pub fn decay_all(&mut self, elapsed_ticks: u64)

Apply time-based decay to all accumulators.

pub fn context_count(&self) -> usize

Number of tracked contexts.

pub fn iter( &self, ) -> impl Iterator<Item = (&ContextKey<V, N>, &CoherenceAccumulator)>

Iterate over all (context key, accumulator) pairs.

pub fn set_fallback(&mut self, value: Option<f32>)

Set the fallback coherence returned for unseen contexts in degraded mode.

Pass None to clear the fallback (unseen contexts revert to 0.0).

pub fn get_or_create( &mut self, key: &ContextKey<V, N>, ) -> &mut CoherenceAccumulator

Get or create the accumulator for key, initialising at the personality baseline.

Evicts the oldest entry when the field is at [MAX_CONTEXTS] capacity.

impl<V: SensorVocabulary<N>, const N: usize> Default for CoherenceField<V, N>

fn default() -> Self

Returns the “default value” for a type.
