Struct ProposedFact 

pub struct ProposedFact {
    pub key: ContextKey,
    pub id: ProposalId,
    pub content: String,
    pub provenance: String,
    /* private fields */
}

An unvalidated suggestion from a non-authoritative source.

Proposed facts live in ContextKey::Proposals until a ValidationAgent promotes them to Fact. The proposal tracks its origin for audit trail.

Fields

key: ContextKey

The context key this proposal targets.

id: ProposalId

Unique identifier encoding origin and target.

content: String

The proposed content.

provenance: String

Provenance information (e.g., model ID, prompt hash).

Implementations

impl ProposedFact

pub fn new( key: ContextKey, id: impl Into<ProposalId>, content: impl Into<String>, provenance: impl Into<String>, ) -> ProposedFact

Create a new draft proposal with explicit provenance.

Confidence defaults to 1.0. Override with with_confidence.

pub fn confidence(&self) -> f64

Returns the confidence value, always in [0.0, 1.0].

pub fn with_confidence(self, confidence: f64) -> ProposedFact

Set an explicit confidence baseline for this proposal.

Use this to establish a starting point, then accumulate criteria with adjust_confidence. The value is clamped to [0.0, 1.0]; non-finite values (NaN, infinity) are treated as 0.0.

For computed confidence (e.g. from a solver), pass the result directly.

pub fn adjust_confidence(self, delta: f64) -> ProposedFact

Adjust confidence by a named step, clamped to [0.0, 1.0].

This is the recommended way to express confidence in suggestors and pack solvers. Use the CONFIDENCE_STEP_* constants as the vocabulary:

use converge_pack::{CONFIDENCE_STEP_MAJOR, CONFIDENCE_STEP_MINOR, CONFIDENCE_STEP_TINY};

let proposal = ProposedFact::new(key, id, content, prov)
    .with_confidence(0.5)                        // baseline
    .adjust_confidence(CONFIDENCE_STEP_MAJOR)    // primary criterion met
    .adjust_confidence(CONFIDENCE_STEP_MINOR)    // supporting criterion met
    .adjust_confidence(CONFIDENCE_STEP_TINY);    // tiebreaker bonus

Prefer this over accumulating a local f64 and calling with_confidence at the end — the clamping is automatic and the intent is explicit at each step.

Trait Implementations

impl Clone for ProposedFact

fn clone(&self) -> ProposedFact

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ProposedFact

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ProposedFact

fn deserialize<__D>( __deserializer: __D, ) -> Result<ProposedFact, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ProposedFact

fn eq(&self, other: &ProposedFact) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for ProposedFact

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
