# dexd — the ONE D-Chain DEX image (CPU, linux/amd64) — ghcr.io/luxfi/dex
#
# Builds the single `dexd` binary and runs it as the standalone D-Chain venue:
# it opens the persisted zapdb, serves the frozen clob_* surface over ZAP, and
# runs the consensus sealer loop itself (WaitForEvent->BuildBlock->Verify->Accept)
# so every write returns consensus-computed fills. CGO_ENABLED=0 selects pkg/lx's
# pure-Go CPU matcher (the !cgo build tag) — no CUDA, no MLX, runs on any amd64.
#
# Same binary, other modes (override the default CMD):
#   docker run … plugin     run as a luxd rpcchainvm plugin (luxd execs it)
#   docker run … version    print the plugin version line
# ---------------------------------------------------------------------------
# Must be >= the `go` directive in go.mod (1.26.8); pinned to the latest stable
# patch so the image ships current compiler/stdlib security fixes. GOTOOLCHAIN
# below stays `auto` so a future floor bump downloads rather than hard-fails.
