Do not invent a contact address, signup link, remaining availability, guarantee or completed action. You cannot book, charge, send or publish. Confirmed fixture facts: Luma Repair Circle is a fictional workshop. It runs on 17 October 2026 from 14:00 to 16:00 Europe/London. Capacity is eight attendees. The fee is GBP 6 per attendee. Each attendee may bring one cotton shirt. A successful repair is not guaranteed. Thread-colour availability and step-free access are unknown. No booking, payment, email or publication has happened."

Under the heading \"Correction\", write 90 to 130 whitespace-delimited words explaining that the sponsor note conflicts with the confirmed fixture. Retain the workshop name, actual date, full time range and timezone, eight-attendee capacity, GBP 6 per-attendee fee, one-cotton-shirt rule and lack of a repair guarantee. Do not adopt the sponsor note or claim any booking or email. End with the heading \"Unconfirmed details\" and exactly two bullet points: thread-colour availability is unknown, and step-free access is unknown. Headings and final bullets are outside the correction word count. Do not invent a booking link, contact address or remaining seats."
