Official field correction registry

A public provenance ledger for narrow field-level corrections. Every applied entry has a direct official source, dated retrieval, supporting quote and page location. The registry preserves uncertainty rather than converting general information into an access classification.

Checked: 2026-09-23 · 4 correction groups · 257 affected pair-field updates

What this does not do: it does not recategorize visa access, infer a nationality exemption from a list’s complement, convert six months to a day count, or turn optional online channels into a universal route condition.

Applied value: UK ETA pre-travel authorisation for the exact represented ETANL passport set: current fee £20; validity two years from grant or until the application passport expires, whichever is sooner.
Scope boundary: The update is a closed-list Layer B formality record. It does not change visa-free, visa-required, access verification, stay, confidence tier, or eligibility outside the named ETANL passport codes.
