Be the first to say “that was me.” It’s the fastest way to make the problem smaller.

An unidentified mistake costs the group time. People check their own work, wonder who to ask, start forming theories, and all of that happens before anyone can begin fixing the actual thing. Three words from you skips the whole search, and the goodwill from that usually outweighs the cost of being the one who did it.

Next time something breaks and you know it was you, say so immediately and attach what you think the fix is. Do not wait to find out whether anyone will trace it. Speed is the part people remember.
