# Quote-join audit

Use when a price row is about to be attached to a benchmarked model, or two ids look similar enough to merge.

1. Compare `catalogueProvider` with `quoteProvider`, and `catalogueId` with `quoteId`, as exact strings.
2. A difference in case is not a match. Do not fold, strip, or alias the ids in this checker.
3. On a mismatch, emit no joined record. A near match is a review, not a join.
4. An exact join says only that the two strings were the same. It does not say the models share quality, context, modality or a price.
5. Empty ids are invalid. Do not fill a missing side with the other side's id.

## Run the local check

Resolve these paths relative to this skill directory, regardless of the project working directory:

```sh
python3 scripts/check.py examples/synthetic.json
python3 scripts/check.py /absolute/path/to/your-input.json
```

The bundled example is **synthetic**, not a current vendor identity. Read and adapt it; never cite it as a market match. The script reads one explicit local JSON file and prints JSON. It makes no network requests and writes no files. Python 3.10+; no dependencies.

Exit codes: `0` both pairs matched exactly; `1` review required, with no joined record; `2` invalid input. Passing validates string equality, not that the vendor and the catalogue are the same product. Do not turn a script pass into a publication permission.

## Input contract

`label`, `catalogueProvider`, `quoteProvider`, `catalogueId` and `quoteId` are non-empty strings.

## Deliverable and limits

Return the joined provider and model id, or withhold the join and name which side differed. Quote the observed strings. A withheld join is not an invitation to pick the nearer id.
