"""Traceability (KM-691): user-facing per-turn provenance.

Captured by a per-request `TraceabilityScratchpad` inside `ChatHandler`, persisted
through a `TraceabilityStore` before the `done` SSE event, and served by
`GET /api/v1/traceability`. Kept separate from Langfuse observability
(`src/observability/langfuse/`), which is engineering-only and PII-masked.
