• File db/register.go — part of check-in [b2dcbb7130] at 2026-10-25 23:02:28 on branch main — ci: check gofmt; format the tree

  Sixteen files had drifted from gofmt: struct and comment alignment, one-line if bodies in auth_test.go, trailing blank lines, and a blank comment line gofmt now puts before an indented block in two delta.go doc comments. The test job now fails on any tracked .go file gofmt would change, and lists it. (user: [email protected], size: 971) [annotate] [blame] [check-ins using] [more...]
