"""Milestone 1 — LLM handler tracing enrichment.
These tests verify the LLM chokepoint span + SKY-8414
`llm.request.completed` event behavior implemented in
`skyvern/forge/sdk/api/llm/api_handler_factory.py`. They serve as regression
coverage for the instrumentation.
Note: OTEL's global TracerProvider can only be set once per process. This
module installs a shared TracerProvider + InMemorySpanExporter on first use
via `_ensure_provider()`. Other test files that also call
`otel_trace.set_tracer_provider(...)` will clobber or be clobbered depending
on import order. If more test files need span capture, move the provider
setup to a session-scoped fixture in conftest.py.
The tests use OTEL's `InMemorySpanExporter` — no OTEL backend, collector, or
network required. Fast and deterministic.

"""End-to-end route tests for workflow_copilot_chat_post.
Covers the three scenarios the debated plan requires:
1. Flag off -> old-copilot path runs, new-copilot is not reached.
2. Flag on, successful turn -> new-copilot handler runs and does not
trigger the restore-on-error branch.
3. Flag on, mid-stream failure -> ``_restore_workflow_definition`` is
awaited so a half-persisted draft is rolled back.
These tests exercise the dispatcher and stream-handler wiring in
``skyvern/forge/sdk/routes/workflow_copilot.py`` without reaching a
real database -- all DB / LLM / agent surfaces are patched.
