# plural audit agent missed missing _few form for russian

## TL;DR

Fixes the plural audit agent passing Russian messages that lack the few form. Check messages against the full CLDR category set per locale. Use when Russian renders the wrong plural and the audit passed. Not for syntax errors.

## The error

```text
Audit passed, but Russian users see the wrong plural form for counts like 2, 3, 4.
```

## Fix it

### Step 1: Check the Russian categories

```bash
node -e "console.log(new Intl.PluralRules('ru').select(2), new Intl.PluralRules('ru').select(5))"
```

Expected: You see Russian needs one, few, many, and other.

### Step 2: Audit the message against all four

```bash
node -e "console.log('list the plural cases in the message and compare')"
```

Expected: You find the few case missing.

### Step 3: Add the missing form and re-audit

```bash
node -e "console.log('confirm the audit now requires all Russian categories')"
```

Expected: The audit catches the gap.

## When to use this

- A locale renders wrong plurals but the audit passed
- The audit only checks one and other

## When NOT to use this

- The message has a syntax error, fix the ICU first
- The plural is wrong in every language, check the count value

## Tool and version compatibility

- Any plural audit agent
- CLDR plural data

## Variant phrasings

### audit misses Arabic dual

Same fix: audit against the full six Arabic categories.

### audit passes but translators skipped a form

The audit must check the message structure, not just key presence.

## Why it happens

Audit agents written against English assume one and other suffice. Russian needs few for 2-4, and a message without it silently falls back to other, which the audit never flagged.

## Edge cases

- Fractions use different categories than integers in some locales
- Explicit =2 cases override categories; audit those separately
- CLDR updates can add categories; re-audit on upgrade
