.dockerignore excludes .git, so util/genbuild.sh finds no repository inside the container and emits "// No build information available", which clientversion.cpp renders as the "-unk" suffix. Every binary produced by ./build.sh --linux-compat therefore self-reports "v1.2.0-unk" and cannot be traced to a commit -- including release artifacts, since this build path is part of the v1.2.0 tag. Pre-generating src/obj/build.h does not survive (genbuild rewrites it when the content differs), and simply un-ignoring .git does not help a linked worktree, whose .git is a file pointing outside the build context. So build.sh computes the version on the host, mirroring genbuild.sh rule for rule -- the nearest tag only when HEAD is that tag and the tree is clean, otherwise v<VERSION>-<short sha> with a -dirty suffix -- and passes it through a BUILD_DESC build-arg that Dockerfile.compat exports as DRAGONX_BUILD_DESC. genbuild.sh honours that variable when set and is otherwise untouched; with git metadata present it emits a byte-identical build.h. Every added git call is guarded with || true because build.sh runs under set -eu -o pipefail: a source tarball, a host without git, or a branch whose only reachable tags are lightweight (v1.0.1-v1.0.3 are lightweight; v1.1.0 is the first annotated one) would otherwise abort the build with no diagnostic. Those cases now degrade to the previous "-unk" behaviour with a warning. A direct "docker build -f Dockerfile.compat" passes no BUILD_DESC and still produces -unk; the Dockerfile now says so loudly rather than silently.
