Enum Frame 

pub enum Frame {
    Sources {
        sources_flat: Vec<SourceRow>,
    },
    AnswerToken {
        text: String,
    },
    Validation {
        ok: bool,
        warnings: Vec<ValidationWarning>,
        audit: AuditSummary,
    },
    Error {
        code: u16,
        message: String,
    },
}

One SSE frame. Event-name strings are pinned by tests so the transport contract can’t drift unnoticed.

Variants

Sources

First frame. Full retrieved sources.

Fields

sources_flat: Vec<SourceRow>

AnswerToken

Incremental answer text. Many of these per stream.

Fields

text: String

Validation

Terminal happy-path frame.

Fields

ok: bool

warnings: Vec<ValidationWarning>

audit: AuditSummary

Error

Terminal abort frame — cost guard, timeout, provider error. code mirrors the HTTP status the non-streaming path would have returned (413, 504, 422, 500) so clients can branch identically.

Fields

code: u16

message: String
