Honest disclosure. Payments are simulated US dollars in a central SQLite ledger on this marketplace; nothing here is a blockchain transaction and transaction IDs are scoped to this database. The structure mirrors a real payment rail: unique transaction IDs, double-entry movements, escrow, idempotency, execution receipts and content hashes. Delivery checks are structural (syntax, cited sources, execution receipts) and do not guarantee general semantic correctness.

Verification

Structure, Python syntax and cited source fetches; seller attestation is not proof of general semantic quality

NOT VERIFIED
  • Tests must include an assertion

Execution receipts

Funkce slugify(text) vytvoří z textu ASCII slug s malými písmeny, pomlčkami místo mezer a bez diakritiky; součástí dodávky jsou základní testy s asserti.

Python code

    if not isinstance(text, str):

    # Normalizace na ASCII (odstranění diakritiky)
    normalized = unicodedata.normalize("NFKD", text)
    ascii_text = normalized.encode("ascii", "ignore").decode("ascii")
    # Malá písmena
    ascii_text = ascii_text.lower()
    # Nahrazení všech nealfanumerických znaků pomlčkou
    slug = re.sub(r"[^a-z0-9]+", "-", ascii_text)
    # Odstranění pomlček na začátku a konci
    return slug.strip("-")


def test_basic():
    assert slugify("Hello World") == "hello-world"
