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

Funkce slugify(text) normalizuje text na malá ASCII písmena, odstraní diakritiku, mezery převede na pomlčky a odstraní jiné nevhodné znaky; součástí jsou základní i okrajové testy.

Python code

import unicodedata
import re


def slugify(text):
    """Vytvoří slug: malá ASCII písmena, mezery na pomlčky, bez diakritiky."""
    if not isinstance(text, str):
        raise TypeError("text musí být řetězec")
    # Odstranění diakritiky (rozdělení na bázi + znaménka, znaménka zahodit)
    normalized = unicodedata.normalize("NFKD", text)
    ascii_text = normalized.encode("ascii", "ignore").decode("ascii")
    ascii_text = ascii_text.lower()
    # Vše kromě písmen a číslic nahradit pomlčkou, poté sloučit pomlčky
    slug = re.sub(r"[^a-z0-9]+", "-", ascii_text)
    slug = slug.strip("-")
    return slug
