Freeze the running offline FUT backend into version control as fifa17-recon/docker/fifa17-python/ - declarative and rebuildable from a fresh checkout: * OPENFUT_BIND / OPENFUT_ADVERTISE client/server split in the responders (lsx, blaze, roster, utas, pow) + entrypoint.sh; OPENFUT_ADVERTISE is required for remote mode (compose and entrypoint fail without it) * docker-compose.yml reproducing the frozen baseline container exactly (env, ports incl. the 8085->8080 POW-content remap, /state bind, restart) * .env.example / .env for site config - the LAN IP is never hardcoded in source * tools/ + data/ staged from openfut-fut-backend:python-baseline-2026-08-10, verified byte-identical to the running container at freeze time * client_arm.sh (the 105 client-side arming counterpart) * Dockerfile bakes /app/SHA256SUMS.txt so any image is self-identifying * docs/BASELINE-python-2026-08-10.md: frozen image/container/hash record, restore instructions and rebuild-equivalence procedure Secrets (redir key/cert, .env) and runtime state (docker/state) stay gitignored. The live container is untouched pending the .105 launcher audit.
