Parameters¶

Name	Type	Required	Description
`claim_kind`	`str`	Yes	Claim kind allowed by the target Truth store profile.
`confidence_extraction`	`float`	No	Optional extraction confidence from 0 through 1.
`conversation_id`	`str`	Yes	Exact durable Work Buddy conversation identity; never a title or text query.
`derivation_relationship`	`str`	No	Typed semantic relationship between message and proposition, normally paraphrase. Defaults to paraphrase.
`evidential_effect`	`str`	No	Typed evidence effect, normally supports. Defaults to supports.
`idempotency_key`	`str`	Yes	Caller-stable key for this exact source and semantic proposal; replay returns the original result and changed reuse conflicts.
`message_id`	`str`	Yes	Exact durable message identity within conversation_id; never message text or ordinal position.
`producer_call_id`	`str`	No	Optional durable identifier for the model call that prepared the proposition.
`producer_model`	`str`	Yes	Model identity for the proposing agent. It must match the gateway session manifest when one records a model.
`proposition`	`str`	Yes	Human-readable proposition the current agent semantically inferred from the addressed message.
`relation_diagnostics`	`dict`	No	Optional diagnostics for the typed evidence relationship; these do not constitute human review.
`scope`	`str`	No	Claim scope. Defaults to store.
`store_id`	`str`	Yes	Exact registered Truth store identity that should receive the proposed claim.
`structured`	`dict`	No	Optional profile-validated structured claim fields.
`valid_from`	`str`	No	Optional ISO 8601 valid-time start.
`valid_to`	`str`	No	Optional ISO 8601 valid-time end.

Details¶

This operation captures or reuses the one Sources item identified by the native conversation_id and message_id, then atomically records its evidence snapshot, whole-message exact span, typed evidence relation, source-resolution receipt, and managed-use receipt alongside a proposed claim. It accepts no source-message text from the caller. Equal text in another message is a different occurrence and cannot satisfy the request.

The gateway session determines the semantic agent actor. The capability has no actor, issuer, tenant, reviewer, or decision parameters that a caller can spoof. Conversation-source authorship remains whatever the durable provider can actually establish; a user role alone is not treated as proof of human authorship.

The result is always a proposal, never confirmation. Use truth_claim_confirm separately when a human has reviewed the exact claim and its receipts. Only that separately gesture-gated transition can make the claim eligible for the configured Truth-to-Hindsight projection.
