Approval‑Streak Early‑Warning Metric

Define and report a simple, weekly 'approval‑streak' metric: the number of consecutive weeks a leader’s net approval sits beyond a chosen threshold (e.g., ≤‑15). Short streak increases (or reversals) would be published alongside raw poll numbers as an operational early‑warning for coalition stress, donor flight, or governing paralysis. — Standardising a streak metric turns noisy polling into an actionable indicator for campaigns, legislators, journalists and funders to anticipate governing fragility and to time oversight or messaging.
