# SYNTHETIC FICTIONAL DEMO — local catalog repair

All five rows are invented for this $0 local experiment. No real products, customers, sales or business results are represented.

| Record | SKU (text) | Fictional product | Before | After |
| --- | --- | --- | --- | --- |
| 1 | `00001` | SYNTHETIC Orbit Print, Small | Price ` 12.5000 `, inventory `7` | Price `12.5000`, inventory `7` |
| 2 | `00002` | SYNTHETIC Orbit Print, Large | Price `18.00`, inventory `0` | Unchanged |
| 3 | `1E03` | SYNTHETIC Moss Card | Price `0.00`, inventory ` 4 ` | Price `0.00`, inventory `4` |
| 4 | `00004` | SYNTHETIC River + embedded newline + Notebook | Price `9.90`, inventory `-2` | Unchanged; negative inventory warning |
| 5 | `DEMO-005` | SYNTHETIC Cloud Poster, A4 / Gray | Price `20.10`, inventory `3` | Unchanged; both explicit options retained |

Five source rows become five variant rows across four product handles. Two numeric edge-whitespace repairs, one warning, zero errors. SKUs are byte-for-byte equal as decoded CSV strings; prices have exact Decimal equality and inventory values are identical. Each candidate has draft status and online publication set to false.

Use `SYNTHETIC-run/before-review.csv` and `SYNTHETIC-run/after-review.csv` for spreadsheet viewing. Their `text: ` prefixes and JSON escapes are deliberate display protection; do not import these views to Shopify. `SYNTHETIC-run/shopify-candidate.csv` is the machine candidate. No live import occurred. `SYNTHETIC-before.csv` is the untouched fictional input; `SYNTHETIC-run/raw-input.csv.bin` preserves its exact bytes.

`SYNTHETIC-run/issues.json` records each repair/warning. `SYNTHETIC-run/manifest.json` hashes the run payloads and processor. `SHA256SUMS.txt` additionally hashes the delivered processor and demo files, including the manifest (excluding itself).

Validation: 27 unittest tests passed. Coverage includes duplicate/conflicting SKUs, blanks versus zeros, signed inventory policy, ambiguous currencies/subcent prices, formula prefixes, invisible characters, multiline CSV, explicit variants, malformed input, bounds, source preservation, output-path restrictions, and deterministic bytes/hashes. Tests exercise CSV serialization and safety checks; no spreadsheet GUI or Shopify import was used.

See `../processor/README.md` for usage, mapping rules and limitations. Repeated conversions require fresh output directories. Excel requires separately verified manual extraction, which was not performed in this demo.
