Conflicts resolved keeping both: Settings and SettingsState carry the sweep fields (miner-eff) and dev_fee /
fee_total (dev-fee); the engine's settings snapshot sets both and the DevFeeState line stays.
Decision of 4 October 2026 (evening): the Igneum Miner software takes a visible, switchable 1% dev fee, the norm
for GPU miners; the protocol stays fee-free. The miner side (--dev-fee, the 1-in-100 template counter, the audit
command) is on branch dev-fee of the node fork.
- app: settings.dev_fee (default on) passes --dev-fee 0 to igneum-miner when off; Settings shows the miner's own
"dev fee 1% (1 block in 100) to 0x..." line next to the rewards address with a switch; the engine parses the
miner's start line and its dev-fee block lines (fee_session, lifetime fee_total, an event per fee block)
- packaging/hive: h-manifest.conf, h-config.sh, h-run.sh, h-stats.sh, make-hive-package.sh (igneum-hive-<v>.tar.gz
with the Linux igneumd, igneum-miner and both GPU workers), README with the Flight Sheet, selftest.sh (bash -n,
stub binaries, the three hooks the way Hive runs them, the stats JSON parsed). Hive itself is untested
- infra/cross/build-workers-linux.sh: the NVRTC and OpenCL workers cross-compiled for Linux with zig;
proto-opencl/cl_dynamic.h gains the Linux dlopen branch (libOpenCL.so.1)
- tools/dev-fee/run.mjs: the fee-block test network (two nodes on 29900+, three CPU miners, payouts audit)
- docs/design/miner-dev-fee.md (mechanism, flag, lines, the DEV_FEE_ADDRESS placeholder and the devnet address),
docs/fud-ledger.md E18 and the E5/L9 status line, litepaper "What a miner's hour looks like" paragraph, homepage

infra/cross/build-linux.sh builds igneumd and igneum-miner for x86_64-unknown-linux-gnu.2.36 (Debian 12) with
cargo-zigbuild 0.23.4 and zig 0.17.0 into vendor/igneum-node/target-linux: rocksdb, lz4, blst, secp256k1 and the
execution layer all link through zig, no crate failed (Docker is absent here, so cross was not needed). Cold build
1,856 s at 4 jobs, nice 19, on a loaded Mac; the seed's own build took 55 min and the builder VM 10 to 25.
Verified on igneum-seed-1 in /root/xbuild-test: igneumd --version, igneum-miner --help, and a 60-s private
network with real proof of work where the cross-compiled miner found 7 blocks that the cross-compiled node
accepted (0 rejected). /opt/igneum/v4/bin untouched.
BIN_SOURCE=mac: provision.sh skips the builder VM and takes build/bin from the cross-compile; stage-v4.sh
cross-compiles, uploads to /root/v4/out and installs exactly as a VM build would.
