server/scenarios/runtime.py — ScenarioRuntime maps a Scenario to a Pipecat
Flows state-machine spec: initial 'conversation' state with the scenario's
system prompt + opening line, branch metadata carried in the spec (v0.1
has no in-flight transitions per G-002 — branching is post-hoc; Phase 2+
can fork without schema change). set_branch() resolves the branch outcome
from the classifier; debrief_focus() returns the per-branch focus.
TASK-03-07: server/pipeline.py build_pipeline() now accepts a scenario_id,
loads the runtime, and uses scenario.setup.system_prompt instead of the
SLICE-02 hardcoded walking-skeleton prompt. Falls back gracefully if the
scenario can't load. server/__main__.py passes
PRAXIS_SCENARIO=customer_service_refund_ca_v01 by default. 7 runtime tests
pass (system prompt, set_branch accept/escalate, unknown-branch error,
debrief_focus per branch, flows spec branches, debrief model config).
