How verification works

This archive treats a personal trip as an auditable dataset. Every published claim carries five things: an as-of date, a source document, a reference (page, line, or receipt), a document hash, and a provenance chain from raw document to published figure.

Status legend

Verified — traced to a primary document in the evidence archive.

Computed — derived from verified inputs; method and inputs shown.

Estimated — contemporaneous operator estimate, labeled as such.

Corrected — superseded; original preserved in the revision trail.

The origin

The underlying trip was the World Race — an 11-month, 11-country volunteer journey I took in 2013–14. The narrative context is part of the story; the data layer stays neutral: costs, routes, venues, dates, documents.

Historical data, stated plainly

These are 2013–14 figures with locked exchange rates as of transaction date. They are published as a historical baseline — the anchor for price-over-time comparisons, not a guide to current prices.
