Conversation
Go's toolchain auto-embeds VCS metadata (revision, modified flag, build time) into binaries built from a git checkout. Read it via runtime/debug.ReadBuildInfo at startup so operators can verify exactly which commit a running golbat was built from. - Remove .git from .dockerignore so VCS info reaches container builds - Log revision/modified/build-time at startup - Add unauthenticated GET /version endpoint returning the same fields plus Go version Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
