## Changelog

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-08-03 (score 69, +1)

No change was recorded against any check on this day. Stability & Change Management went from 20 to 23. That category is still filling its 30-day observation window: 6 days of observed history at the previous scan, 7 at this one. The score rises as the window fills, whether or not the server changes.

### `extract_i18n_keys` (~98 tokens)

Input parameters:

- `language` (string): The source language/framework of the code
- `sourceCode` (string, required): The source code to analyze for hardcoded strings

### `analyze_translations` (~140 tokens)

Analyze translation JSON files for consistency across locales. Finds missing keys, extra keys, structural mismatches, interpolation variable differences, and empty values. Optionally identifies unused keys given a list of keys referenced in source code.

Input parameters:

- `locales` (object, required): Object mapping locale codes to their translation JSON objects, e.g. { "en": { "greeting": "Hello" }, "fr": { "greeting": "Bonjour" } }
- `referenceLocale` (string): The reference locale to compare all others against (default: en)
- `usedKeys` (array): Optional list of translation keys actually used in source code, to find unused keys

### `plural_rules` (~146 tokens)
