}

A source-bound piece of supporting material: where it came from, the literal content, and optional span offsets into the source. The payload of an evidence record.

Fields

id: EvidenceId

Evidence id, unique within the scope.

tenant_id: TenantId

Owning tenant.

project_id: ProjectId

Owning project.

source_uri: String

URI/path of the source artifact (e.g. “s3://antares/calls/2026-04-29.vtt” or “antares://transcripts/meeting_001”). Required.

source_type: String

What kind of source: “transcript” | “email_event” | “crm_field” | …

source_id: String

Identifier of the source event/artifact (e.g. “meeting_001”, “email_001”). Required.

content: String

The literal text/data the evidence points at. Required.

char_start: Option<u32>

Character offset of the span start in the source, inclusive.

char_end: Option<u32>

Character offset of the span end in the source, exclusive.

byte_start: Option<u64>

Byte offset of the span start in the source, inclusive.

byte_end: Option<u64>

Byte offset of the span end in the source, exclusive.

observed_at: Option<DateTime<Utc>>

Wall-clock time the source event happened or was seen.

extracted_at: Option<DateTime<Utc>>

Wall-clock time the extractor produced this record.

extractor_version: Option<String>

Version tag of the producing extractor, verbatim.

confidence: Option<f32>

Confidence in [0,1]. None = treated as 1.0.

metadata: Value

Free-form metadata. Use sparingly — first-class fields above are preferred.

author: Option<AuthorStamp>

Which user persisted this evidence. None for older records and for anonymous calls.
