7-day shutdown-risk estimate · validation pending

Congo (Brazzaville) — 3% risk

A seven-day view of the current regime, with drivers and supporting evidence. This is not a shutdown-onset prediction.

Reading this forecast & citation

The Voidly Sentinel model scores Congo (Brazzaville) at a peak 2.7% shutdown-risk level over the next 7 days, highest on day 4 (Mon, Oct 26). Average across the window: 2%. This is a current-regime risk reading, not a prediction that a new shutdown will start — see the scope note below.

May 2026 legacy-model audit: the audited forecast mainly tracked existing blocking regimes, not new shutdown onsets. On the days a new shutdown began, its transition-row AUC was ~0.33. This historical result is not a current production scorecard. Why →

Honest caveats

Legacy forecast: May 2026 audit

A May 2026 audit of the then-production 7-day forecast found that it mainly tracked existing blocking regimes and did not reliably predict new shutdown onsets. The figures below describe that legacy model, not a current production scorecard.

In that audit, a forward-temporal split (train on the past, test only on the strictly-future window) gave the legacy model AUC 0.589 on its raw label — near chance.
The audited label target_7day was a 7-day sliding window, so it is 98.9% autocorrelated day-to-day. A trivial predict-yesterday baseline scores AUC 0.957 — high numbers here mean “what is blocked stays blocked,” not predictive skill.
On the rows where a shutdown actually began (transitions), the legacy forecast scored AUC ~0.33 — below chance.

Read any current 7-day risk number as a source-reported signal. These historical audit figures do not validate current onset skill. Interval coverage is unvalidated and the bounds are withheld here; do not use this as an early-warning siren. Read the full honest re-evaluation →

The 2026-05-20 isotonic refit is historical. Its 810 archived pairs do not establish current calibration or onset skill.
A 70% forecast doesn't mean a shutdown is guaranteed; a 20% forecast doesn't mean it's safe. Source-reported interval fields have no verified empirical coverage here.
