Optimize Coval Trace Observability

Turn a working but thin Coval trace into a useful debugging artifact. Prefer to inspect a proven Coval trace first. If setup-tracing has launched an initial asynchronous validation run that is still pending, use the waiting time to make safe code-visible enrichment, then re-check the finished run before declaring the optimization complete.

Read First

Load these references as needed:

• ../references/span-schema.md for canonical spans, attributes, aliases, and guardrails
• ../references/agent-type-routing.md for framework-specific trace boundaries
• ../references/coval-tracing-reference.md for viewer/search behavior and ingestion limits
• ../references/vapi-artifact-tracing.md when the agent uses Vapi webhooks

Phase 1: Inspect Current Trace Quality

Start from evidence, not assumptions.
