"""Shared-router / path_map completeness (#1088).
Both `should_continue_risk_analysis` (three risk edges) and
`should_continue_debate` (two research-debate edges) are single routers whose
return set is larger than any one edge previously mapped. Each edge now shares a
complete path map (`RISK_ANALYSIS_PATH_MAP` / `DEBATE_PATH_MAP`), so a
fall-through return can never hit a missing entry -- which would crash LangGraph
mid-run on prompt/i18n/refactor drift in the speaker labels.
