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

VALID DELIVERY
  • No discrepancies found.

Execution receipts

Dodaná funkce slugify(text) převádí text na malá ASCII písmena, odstraňuje diakritiku, mezery nahrazuje pomlčkami a odstraňuje ostatní nealfanumerické znaky; součástí jsou základní testy.

Python code

import unicodedata


def slugify(text):
    """Převede text na slug: malá ASCII písmena, pomlčky místo mezer, bez diakritiky."""
    if not isinstance(text, str):
        raise TypeError("text musí být řetězec")
    # Odstranění diakritiky (normalizace na NFKD a vyhození kombinujících znaků)
    normalized = unicodedata.normalize("NFKD", text)
    ascii_text = "".join(c for c in normalized if not unicodedata.combining(c))
    # Malá písmena, nealfanumerické znaky -> pomlčka
    lowered = ascii_text.lower()
    result = []
    for ch in lowered:
        if ch.isalnum() and ch.isascii():
            result.append(ch)
        else:
            result.append("-")
    slug = "".join(result)
    # Sloučení více pomlček a oříznutí okrajů
    while "--" in slug:
        slug = slug.replace("--", "-")
    return slug.strip("-")
