igneum-labs dc33031c3a Igneum Miner 0.3.3: an unattended Windows miner is never stranded by an update (4 Oct 15:40 incident: both PCs stopped at the installer's UAC prompt). Per-user installer (PrivilegesRequired=lowest, %LOCALAPPDATA%\Programs, migration from Program Files offered only when someone is at the keyboard, firewall rule asked once on first run and mining without it); the Windows helper runs the installer FIRST with the engine still mining and only the installer's own stop step ends it, a declined or unanswered prompt leaves the machine mining with "OTA: waiting for administrator approval" / "administrator approval not given; waits for the next time someone is at this PC" in the log and the intake, retry on Install now, next start or 6 h; machines take turns (apply only in the minute = machine id8 mod 60) and hold while /api/live shows over 30% of identities gone in 10 minutes

Igneum Miner for Windows (packaging/windows)

Inno Setup installer around the app payload. Version 0.3.0 (4 October 2026): the app (engine + window host) instead of the console launchers of 0.1.0.

Built on GitHub, not on a PC (4 October 2026)

.github/workflows/windows.yml builds the whole Windows app on a hosted Windows runner on every push to master that touches app/, packaging/windows/, proto-cuda/windows-*, proto-cuda/nvrtc/, proto-opencl/, proving/windows-wsl2/ or relay/clients/ (and on gh workflow run windows.yml). Nobody runs BUILD-APP.bat or BUILD-INSTALLER.bat on a PC any more; both files stay for a hand build and the workflow runs them as they are.

Two jobs:

parse (required): every .ps1 under the Windows folders through the Windows PowerShell 5.1 parser (tools/ci/windows/check-ps51.ps1, run with powershell.exe, the PowerShell on the PCs; it refuses to pass unless the fixture tools/ci/windows/fixtures/bad-drive-ref.ps1.txt, a "$x: y" drive-qualified reference, FAILS, so a green run proves the check bites), PSScriptAnalyzer as warnings, and a parenthesis check of every .bat and .cmd (check-bat.ps1: caret escapes, quotes and for /f ('...') strings ignored, depth never below zero, zero at the end; its fixture bad-bare-paren.bat.txt must be flagged). Both scripts run on a PC too: powershell -NoProfile -ExecutionPolicy Bypass -File tools\ci\windows\check-ps51.ps1.
build: the engine with cargo build --release on the MSVC target (so the Mac cross-build is no longer an input), the window host with app\windows\BUILD-APP.bat as it is (MSVC from the runner's Visual Studio, WebView2 SDK from NuGet, host.rc with the coin icon; version.h carries the host version), the payload with make-payload.sh in Git Bash, the installer with build-installer.ps1 (Inno Setup from the runner image or chocolatey, rcedit), then a smoke run (igneum-app.exe --version, Igneum Miner.exe --version and --help, the version block of the host), the launcher proto-cuda/windows-app/start-igneum.ps1 with DRY_RUN=1 (prints the node command and the GPU plan, starts nothing) through the .ps1 and through START-IGNEUM.bat, and three artifacts kept 90 days: igneum-windows-installer (Igneum-Miner-Setup-<version>.exe), igneum-windows-payload (igneum-windows-app.zip), igneum-windows-host (Igneum Miner.exe).

The inputs the runner cannot build

igneumd.exe and igneum-miner.exe come from the node fork in vendor/ (not in git, 20 to 55 minutes to build) and the prebuilt GPU workers need NVIDIA's NVRTC DLLs (90 MB, not in git). They travel as payload-inputs.zip on the downloads host:

packaging/windows/push-inputs.sh            # on the Mac, after each node or worker cross-build

collects igneumd.exe, igneum-miner.exe, the three mingw DLLs, igneum-worker-cuda.exe, nvrtc*.dll, the licence texts, igneum-worker-opencl.exe and an inputs.json (sha256 and bytes of each, the commits, the date), zips them into dl/<token>/payload-inputs.zip with payload-inputs.sha256 and payload-inputs.json next to it in the downloads folder (~/.config/igneum/dlsite-dir names it; IGNEUM_DLSITE overrides), and deploys the folder with the Vercel CLI (--no-deploy to skip). The workflow downloads the three with the DL_TOKEN repository secret and checks the sha256. The secret was set once from the Mac and never printed:

tr -d '[:space:]' < ~/.config/igneum/dl-token | gh secret set DL_TOKEN --repo igneum-network/igneum

The outputs, back to the downloads host

The runner cannot deploy the downloads project (it is deployed by CLI from a folder outside the repo with the Igneum Vercel login), so the Mac pulls the artifacts:

packaging/windows/fetch-ci-artifacts.sh [--deploy] [run-id]

downloads the installer and the payload zip from the latest green run on master (gh run download, as igneum-labs), copies them into dl/<token>/ next to the Mac-built packages, writes igneum-windows-ci.json (run URL, time), and prints the deploy command, or deploys with --deploy.

Over-the-air updates (4 October 2026)

The installed app updates itself: packaging/ota/README.md. fetch-ci-artifacts.sh adds the installer it copies to the signed manifest (igneum-app-latest.json), --deploy ships both, and every app downloads the installer within the hour and runs it /VERYSILENT /IGNOTA=1 in its own minute of the hour (Igneum-Miner.iss has CloseApplications=yes and a [Run] relaunch for that flag). Since 0.3.3 the installer is per user (PrivilegesRequired=lowest, %LOCALAPPDATA%\Programs\Igneum Miner): no administrator prompt, ever, for an update (4 October 2026: two unattended PCs sat at a UAC prompt for an hour); the inbound firewall rule is asked for once by the app on its first run. PC 2 steps: packaging/ota/TEST.md. The console launcher packages (proto-cuda/windows-app, igneum-windows-v4.zip) are not auto-updated, by design: they are the engineering path and are replaced by hand.

What still needs a human

A code-signing certificate. Until Igneum has one, the installer and the exes are unsigned and SmartScreen shows "Windows protected your PC" (More info, Run anyway). Everything else in this folder runs without a PC.

On the Mac (hand build, kept for reference)

packaging/windows/make-payload.sh [out.zip]

Assembles packaging/windows/igneum-windows-app/ and zips it (default ~/Desktop/igneum-windows-app.zip, about 27 MB): igneum-app.exe (the engine, app/igneum-app cross-compiled with the mingw toolchain exactly as igneumd.exe is: cargo build --release --target x86_64-pc-windows-gnu with the environment of proto-cuda/windows-node/cross-build.sh; it links against system DLLs only), igneumd.exe and igneum-miner.exe (the devnet-v4 cross-build), the three mingw runtime DLLs, the prebuilt one-click workers when they exist (proto-cuda/nvrtc/igneum-worker-cuda.exe with NVIDIA's nvrtc64_*_0.dll and nvrtc-builtins64_*.dll and the licence texts, proto-opencl/igneum-worker-opencl.exe), the worker sources for the fallback build (proto-cuda\, proto-opencl\), igneum-app.json (update manifest URL with the token from ~/.config/igneum/dl-token, log intake, live page), stop-igneum.ps1, and app\windows\ (the window host sources and BUILD-APP.bat, since WebView2 cannot be linked from the Mac).

On the PC (hand build, kept for reference; CI does all of this)

Extract the zip next to packaging\windows (or anywhere: build-installer.ps1 -Payload <folder>; without a folder it downloads dl.igneum.network/igneum-windows-app.zip).
Optional, for the app window: igneum-windows-app\app\windows\BUILD-APP.bat. Needs Visual Studio with the MSVC v143 x64 component; it fetches the WebView2 SDK from NuGet, compiles host.cpp with the static loader and copies Igneum Miner.exe into the payload. Without it the Start Menu entry runs igneum-app.exe --launch, which opens the dashboard in the default browser (same engine, same screens).
packaging\windows\BUILD-INSTALLER.bat: installs Inno Setup 6 through winget if missing, stamps the coin icon and the version block into igneum-app.exe, igneumd.exe and igneum-miner.exe with rcedit unless they carry one, compiles Igneum-Miner.iss, writes dist\Igneum-Miner-Setup-0.3.0.exe.

The installer: Program Files\Igneum Miner, Start Menu group (Igneum Miner, Stop Igneum Miner, Igneum Miner logs, Uninstall), optional desktop icon and firewall rule for igneumd.exe on private networks, "Start Igneum Miner now" on the finish page (as the signed-in user), stop-igneum.ps1 before an upgrade and on uninstall (it POSTs api/quit to the running engine through %LOCALAPPDATA%\igneum\app\app.url, waits, then ends what is left), licence page (MIT placeholder, pending), finish page with the seed line. Data: %LOCALAPPDATA%\igneum\devnet-v4 (the chain, the same folder the 0.2.0 launcher used), %LOCALAPPDATA%\igneum\app (settings, wallet.json locked to the user with icacls, the hourly program packs), %LOCALAPPDATA%\igneum\logs. Unsigned until Igneum has a code-signing certificate: SmartScreen warns (More info > Run anyway).

What the engine does on Windows

GPU detection: nvidia-smi --query-gpu=index,name,memory.total for NVIDIA (Discrete, VRAM), the OpenCL worker's --list for the rest (AMD, Intel; Integrated by name: "Radeon Graphics", "Iris", "UHD"), the WMI names as a last resort. Discrete cards default on (8 identities at 8 GB and up, else 2), integrated off with the reason shown. Each enabled card gets its own miner process: igneum-miner mine grpc://127.0.0.1:26610 1 100000000 nvidia-<pc>[-n] --worker <igneum-worker-cuda.exe> --status-secs 30 --exit-on-seed-change --prepare-packs packs\prepare --evm-address <addr> [--identities N] --payout-label <label> --worker-args "--device N --pack packs\devnet" (cwd %LOCALAPPDATA%\igneum\app, so the pack paths stay relative; the OpenCL worker adds --job-nonces 2097152). Before each start the engine runs igneum-miner export-pack for the prebuilt worker; without a prebuilt worker it runs today's build path (proto-cuda\build.bat devnet sm_120 in the MSVC environment, rebuilt at every hour boundary after exit 42), exactly as igneum-common.ps1 falls back.

Devnet vote keys are test keys derived from the miner's label; mainnet vote keys will be random and stored like the wallet (R4.3.12, devnet-only by design). Program Files stays read-only for users: the engine writes only under %LOCALAPPDATA%\igneum, and every helper (nvidia-smi, powershell, cmd, curl, reg, icacls) is launched by its absolute path.

Untested at the time of writing (written on a Mac): the window host (app/windows/host.cpp, first run is BUILD-APP.bat), the Inno build, nvidia-smi and OpenCL detection, the prebuilt workers under the engine. embed-resources.sh (windres + relink on the Mac) still works for igneumd.exe and igneum-miner.exe; the engine's icon comes from rcedit on the PC.
