Struct ChainFailure 

pub struct ChainFailure {
    pub error: String,
    pub failed_stage_idx: u32,
    pub elapsed_stages: u32,
    pub elapsed_ms: u64,
    pub stage_error: String,
}

Structured error payload returned in the 502 response body when a chain stage fails mid-run. Allows UIs to show actionable retry hints (e.g., “stage 2 of 5 failed — retry from here”).

Fields

error: String

Human-readable summary of where the failure landed.

failed_stage_idx: u32

Zero-based index of the stage whose render returned Err.

elapsed_stages: u32

Number of stages that completed successfully before the failure.

elapsed_ms: u64

Cumulative generation time across the completed stages, in ms.

stage_error: String

Inner error message from the orchestrator (format!("{e:#}")).
