start-sdk pack was failing on 'Copying Assets: No such file'
because the compat volume was declared with type: assets but
had no assets/compat/ directory to populate it.
start-sdk pack discovers per-arch tarballs at docker-images/
x86_64.tar and docker-images/aarch64.tar by filename convention,
not via a manifest assets entry. Dropping the invalid
'docker-images: image.tar' assets key and reworking the Makefile
to build one type=docker tarball per arch with arm/x86 single-
arch convenience targets.
Multi-stage Dockerfile clones KamadoPool at a pinned SHA, builds
ckpool and kamado-api (with embedded Svelte UI), runtime image
supervises both processes via tini + wait -n. Config covers
bitcoind mainnet/testnet4 variant, payout address, coinbase tag,
vardiff knobs, and log level. Web UI interface only — stratum
:3333 requires a router port-forward or simpleproxy workaround
because StartOS 0.3.x does not forward raw TCP on LAN.
TODO before first build: pin KAMADO_REPO + KAMADO_SHA in the
Dockerfile to a pushed commit.
