// Unit tests for src/main/profiles.js — targeted at leafPathFor, the seam
// the Plugins tab reads to answer "which yaml is this profile actually
// booting from?". The previous behavior hardcoded daemon-echo.yml under
// activeBasePath() in main.js, so the Plugins tab under stdio-deepseek
// showed the wrong leaf and the runtime fold reconciled against noise.
// QA round-3 shot 07 (2026-07-16) caught the regression; team-lead
// asked for a pin here so switching the leaf mapping later can't drift
// silently.
