A daily, machine-scored operability gauge for inland African supply corridors.

Ships are tracked to the metre. The moment cargo goes inland in Africa, the data goes dark — yet that is where the risk lives. Fuel moves in and minerals move out through the same restricted corridors, through the same single gates. When a gate fails, a mine's input and its output fail together.

Violence on these routes is chronic; stoppage is usually fiscal — a customs post, a permit, a levy. We score the state either way, every day.

One corridor gate. One score per day. Scored by machine against a frozen rubric and a fixed register of public sources — never by opinion, never in hindsight.

The proof is not trusting the operator. The proof is that you can run it yourself.

• RubricFrozen before scoring starts. Changes only through a documented amendment process.
• SourcesA public source register. Anyone can see what the gauge reads, and read it themselves.
• LedgerDaily scores in a hash-chained ledger, anchored to Bitcoin via OpenTimestamps. Quiet rewriting is detectable by design.
• CertifierAn independent certifier governs every methodology change.
• Design principleManipulation cost scales with payout size and duration — and every attempt writes its own evidence trail.

Kasindi–Mpondwe, the DRC–Uganda border gate: the single fuel gate for the Beni–Butembo basin in eastern DRC, fed by a single trunk from Mombasa with no redundant route.

The method transfers: any bottleneck corridor can be scored the same way — the source register is the only corridor-specific work.

Reinsurance and parametric underwriters. Mining operators. Fuel supply-chain operators. Traders and financiers with inland African exposure. Anyone whose loss begins at a gate the market does not measure.
