Struct ConfidenceScore 

pub struct ConfidenceScore {
    pub value: f32,
    pub confirmation_count: u32,
    pub contributor_count: u32,
    pub last_challenged: Option<u64>,
    pub challenge_count: u32,
}

How much the system trusts this record’s accuracy.

Formula (ARCHITECTURE.md §13.1):

base_score:
  DeveloperManual → 0.80
  Import          → 0.70
  ClaudeEnrich    → 0.60
  SessionHook     → 0.50
  StaticAnalysis  → 0.10

confidence = base_score
  × log2(confirmation_count + 2)
  × min(contributor_count, 3) / 3
  × recency_weight(last_accessed)   90-day half-life
  × ref_boost                       1.5× if ref_url set

Recomputed on every mem_get, written back with Durability::Eventual.

Hook injection thresholds:

>= 0.6 + confirmed  → deny file read, inject record
0.3 – 0.6           → allow read + attach as additionalContext
< 0.3               → allow read, no injection

Does not derive PartialEq — see module-level float equality note.

Fields

value: f32

0.0 → 1.0

confirmation_count: u32

How many times this record has been explicitly confirmed correct.

contributor_count: u32

How many distinct contributors have written or confirmed this record.

last_challenged: Option<u64>

Unix timestamp of the last time this record was challenged or disputed.

challenge_count: u32

Implementations

impl ConfidenceScore

pub fn base_for_source(source: &RecordSource) -> f32

Initial confidence value for a freshly created record by source type.

pub fn for_new_record(source: &RecordSource) -> Self

Construct a ConfidenceScore for a newly created record.

Sets value from base_for_source and zeros all counters. Use this instead of constructing manually to prevent value from diverging from the source-derived base.

Trait Implementations

impl Clone for ConfidenceScore

fn clone(&self) -> ConfidenceScore

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ConfidenceScore

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ConfidenceScore

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for ConfidenceScore

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
