/**
 * v2.15.0 follow-up — G14: smoke regression state service.
 *
 * Tracks the project's "critical paths" — the 5-10 paths the user
 * (or the QA agent) must verify in 5-10 minutes before shipping.
 * Persistence: `.peaks/smoke-paths.json` in the project root.
 *
 * The actual path execution (Playwright / curl / manual) is OUT OF
 * SCOPE for this slice — this ships the model + the run-result
 * record path. A follow-up slice wires real Playwright integration.
