Spanish shipped last week and the metrics screen has said {{periodo}} to every user since. The catalogue had every key. It parsed. The placeholder came back from machine translation with its name translated too, which compiles perfectly and renders the literal.

i18n-le locales/

i18next ^26.2.0 — i18next in ../package.json, double-brace, useTranslation( in ../src/app.tsx
de.json: structure app (a string here, an object in the source)
es.json: placeholder renamed metrics.window (timeframe became periodo)
es.json: missing dashboard.empty.title
fr.json: duplicate app.greeting (defined 2×)
4 findings across 25 catalogues

This repository

Everything that is the product lives in crate/ — the Rust CLI, the MCP server, the library table, the corpus and the tests. There is no VS Code extension beside it and no npm package.

crate/README.md is the user-facing document: what it checks, how it works out which i18n library you use before it reads anything, plurals, formats, options, output, running it as an MCP server, and installation. It is not duplicated here — two copies of one long document is the drift this family spends its gates preventing.

Install

cargo install i18n-le

Or build from this repository:

cd crate
cargo build --release
