Day 27 of Tibo Sottiaux's 28-day Codex challenge was a banked reset, under his Day 26 promise that the final two days would be 'resets… banked'. Monitoring accounts first observed a new banked Codex reset landing at 19:59:29 UTC on Saturday, October 31 — 12:59 p.m. in Tibo's Pacific time — and Tibo himself has since confirmed the first of the pair, posting simply 'Banked 1/2' at 00:43 UTC on November 1. Reset trackers now record a banked credit issued at 00:43 UTC.

That post replaces this entry's original caveat: the landing is no longer only a monitor observation with no word from Tibo. What remains unverified is scope — the 'Banked 1/2' post does not specify eligible plans, and a banked reset works differently from the challenge's usual global resets in any case: it lands as a saved credit on the account and only takes effect when the user redeems it, so check your account rather than expecting usage to refill on its own.

One banked reset remains: Day 28, on Sunday, November 1, is the challenge finale. As of Sunday morning Eastern time the second credit had not been posted or verified, and the challenge trackers still showed Day 28 as waiting for Tibo.
