Execution trace capture (RFC 0001).

Modules

Item	Description
`capture`	Task-local capture scope for the unified trace format.
`replay`	Replay scope: serve `Predict` calls from a recorded `Trace` (RFC 0001 §4d/§4e).
`serialize`	JSONL wire format for `Trace`: header line, span lines, optional footer.
`span`	The unified trace format (RFC 0001): one `Span` per `Predict` invocation, one `Trace` per rollout.

`trace::capture`

Task-local capture scope for the unified trace format.

Structs

Item	Description
`SpanGuard`	Owns a `SpanId` — event/close attribution travels with the guard, never through “innermost open span” lookups, so interleaved `Predict`s on one task (`futures::join!`) cannot cross…
`SpanOutcome`	Everything recorded lazily at span close.
`SpanRequest`	Everything recorded eagerly at span open.
`TraceSink`	Shared handle to an in-progress trace.

Functions

Item	Description
`begin_span`	Opens a span in the active capture scope. Returns `None` when no scope is active — the caller does nothing else in that case (zero-overhead path).
`capture_with_meta`	`capture` with caller-provided rollout metadata (input, candidate hash, tags). Missing `trace_id`/`started_at_us` are minted at scope start.
`capture`	Runs `f` while recording every `Predict` call on this task into a `Trace`.
`is_capturing`	Returns `true` if the current task is inside a `capture` scope.

`trace::replay`

Replay scope: serve Predict calls from a recorded Trace (RFC 0001 §4d/§4e).

Structs

Item	Description
`ReplayReport`	What a replay scope did, returned by `replay` alongside the closure’s result.

Enums

Item	Description
`ReplayError`	Why a call could not be served from the recording.
`ReplayMode`	How a replay scope treats a call that does not match its recording.

Functions

Item	Description
`is_replaying`	Returns `true` if the current task is inside a `replay` scope.
`replay`	Runs `f` with `trace` as the canned-response source for every `Predict` call on this task. Returns the closure’s result and a `ReplayReport` of what was served versus live.

`trace::serialize`

JSONL wire format for Trace: header line, span lines, optional footer.

Constants

Item	Description
`TRACE_FORMAT_VERSION`	Highest format version this reader understands.

`trace::span`

The unified trace format (RFC 0001): one Span per Predict invocation, one Trace per rollout.

Structs

Item	Description
`CompId`	Per-trace interned component index. The component name is the same string the params system addresses: an fx slot name (`"drafter"`) or a facet dotted path (`"pipeline.rater"`).
`Eval`	The metric result type: one score, optional textual feedback.
`ModelEntry`	Interned model configuration: `LMConfig` minus live state, minus secrets.
`ModelId`	Per-trace interned model configuration.
`PrefixEntry`
`PrefixId`	Per-trace interned prompt prefix (system message + demo turns). One entry per distinct (component, candidate) configuration — demos serialize once per trace, not once per span.
`Span`	One `Predict` invocation: one rendered prompt in, one parsed output out, with the tool loop’s inner structure as ordered events.
`SpanError`
`SpanId`	Index of a span within its trace. Dense, assigned in insertion order.
`Trace`	One rollout: ordered spans plus per-trace intern tables.
`TraceMeta`
`TraceOutcome`

Enums

Item	Description
`SpanErrorKind`
`SpanEvent`	Ordered events inside a span. Tagged; readers skip unknown tags — this is the streaming seam (RFC 0001 §6).

Type aliases

Item	Description
