One event in a run’s stream. Serialized as JSONL, tagged by event.

Variants

RunStarted

The run began. Head of every stream; declares the schema version.

Fields

schema: u32

Event schema version (EVENT_SCHEMA_VERSION).

run_id: Arc<str>

Injected run identifier (uuid-v7-derived; core never generates it).

ScenarioStarted

A scenario began executing.

Fields

scenario: Arc<str>

Scenario name as authored.

file: Arc<str>

Feature file the scenario comes from.

timestamp_ms: Option<u64>

Milliseconds since the run began — injected at the CLI sink (the sans-IO core leaves it None, like run_id). Absent on records without timing; additive (ADR-0008, ADR-0015).

worker: Option<u64>

0-based worker index this scenario ran on — injected at the sink.

BatchStarted

A batch of contiguous same-engine steps was dispatched.

Fields

scenario: Arc<str>

Scenario name as authored.

engine: Arc<str>

Engine executing the batch.

steps: usize

Number of steps in the batch.

EntryRunning

An artifact entry began an execution attempt — the engine’s live progress signal (ADR-0001’s EventListener, surfaced on the spine). Additive schema variant: absent from pre-existing streams.

Fields

scenario: Arc<str>

Scenario name as authored.

engine: Arc<str>

Engine executing the entry.

entry: usize

0-based entry ordinal within the scenario’s artifact.

retry: u32

Retry number of this attempt (0 = first attempt).

StepFinished

A step finished (in success or failure).

Fields

scenario: Arc<str>

Scenario name as authored.

engine: Arc<str>

Engine that executed the step.

step: StepRef

Anchor to the authored feature line.

status: Status

Outcome status.

attempts: u32

Number of attempts made.

duration_ms: u64

Wall-clock duration in milliseconds.

captures: Vec<String>

Names (never values) of captures produced by this step.

detail: Option<String>

Failure detail, when the step failed (additive schema field — absent on passing steps, so pre-existing streams are unchanged).

attempt_details: Vec<String>

Messages from earlier, failed attempts of a step that ultimately passed — the flaky-failure detail (JUnit <flakyFailure>). Additive schema field: empty (and unserialized) for the common single-attempt step, so pre-existing streams are unchanged.

ScenarioFinished

A scenario finished.

Fields

scenario: Arc<str>

Scenario name as authored.

file: Arc<str>

Feature file path — together with scenario, the run-wide identity (scenario names are unique only within one file). Defaults empty when replaying records that predate the field (schema 1 is additive-only — ADR-0008).

status: Status

Aggregate scenario status.

timestamp_ms: Option<u64>

Milliseconds since the run began — injected at the CLI sink (the sans-IO core leaves it None, like run_id). Absent on records without timing; additive (ADR-0008, ADR-0015).

worker: Option<u64>

0-based worker index this scenario ran on — injected at the sink.

RunFinished

The run finished. Tail of every stream.

Fields

passed: usize

Scenarios that passed.

failed: usize

Scenarios that failed.

skipped: usize

Scenarios that were skipped.

cancelled: bool

The run was cancelled before completing (additive schema field — absent means false, and false is not serialized, so pre-existing streams and snapshots are unchanged).
