When v2.0.0 added the golang.org/x/image/webp dependency (used by the media scrubber for WebP decoding), go mod tidy bumped the module's minimum Go version in go.mod: module go-blockchain go 1.25.0 The three Dockerfiles in the repo were still pinned to older images: /Dockerfile FROM golang:1.24-alpine /deploy/prod/Dockerfile.slim FROM golang:1.24-alpine /docker/media-sidecar/Dockerfile FROM golang:1.22-alpine Result: `docker build` on any of them fails at `go mod download` with go: go.mod requires go >= 1.25.0 (running go 1.24.13; GOTOOLCHAIN=local) because Alpine's golang image pins GOTOOLCHAIN=local to keep the toolchain reproducible. Fix: bump all three to golang:1.25-alpine. The media-sidecar module doesn't actually need 1.25 (it's self-contained and only uses stdlib), but keeping all three in sync avoids surprise the next time somebody adds a dep.
