## TL;DR

The OCR returned character soup in the merchant field. Validate the field (reject strings with too few dictionary words or too many symbols), then fuzzy-match the raw text against the known vendor list to recover the real merchant.

## Error

```text
agent failed to parse the receipt text: ocr garbage in merchant field
```

## Steps

1. Score the merchant field: flag it if it contains excessive symbols, single-character runs, or no recognizable words. Expected: garbage fields are identified mechanically.
2. Fuzzy-match the raw OCR text against the known vendor list (edit distance on normalized strings). Expected: the closest real vendor, with a similarity score.
3. Accept the match only above a confidence threshold; below it, leave the merchant blank for manual entry. Expected: no confident-wrong merchants.
4. Log the garbage strings per vendor to spot systematic OCR failures (stylized logos, thermal fade). Expected: a list of vendors needing manual handling.
5. Consider re-running OCR with different preprocessing on the worst offenders. Expected: some garbage resolves to clean text.

## When to use

- OCR fills the merchant field with unreadable garbage.
- The receipt image itself is marginal quality.

## When not to use

- OCR returns empty (see the faded-receipt skill).
- The merchant is wrong but readable (see the merchant-extraction skill).

## Tool compatibility

- Tesseract, cloud OCR; fuzzy matching in custom agents.

## Variant phrasings

### Merchant field contains OCR noise

Same failure, alternate wording.

### Unreadable merchant on scanned receipt

The image-quality phrasing.

## Why it happens

Stylized logos, decorative fonts, and low-contrast headers produce character-level noise. The OCR emits its best guess, which reads as garbage to downstream matching.
