… + ccache Apply the #439 fork-gate to every ubuntu-24.04 job: push/internal-branch PRs run on [self-hosted, Linux, X64, c2pool-build] (VM905, 32 cores); fork PRs fall back to GitHub-hosted ubuntu-24.04. Build stays -j$(nproc) (=32 on the box). Wire ccache as the C/C++ compiler launcher on the six C++ build lanes (linux, linux-asan, coin-bch, coin-bch-asan, qt, dgb-auxdoge) and add the ccache package to their apt lists so the binary is present on both self-hosted and fork-fallback runners. Completes the all-lane self-hosted switch (Linux+macOS+Windows).

…romium Two self-hosted-environment gaps on the #439 switch (not code): - Linux x86_64 + ASan twin: reused workspace left a stale build_ci/ build_asan, so ctest re-included empty gtest_discover_tests POST_BUILD files -> Unknown CMake command gtest_discover_tests_impl, exit 8. Add a self-hosted-only clean of each Linux build dir before configure (ccache keeps recompiles fast). Applied to all five Linux C++ lanes. - Web-static verify: VM905 only ships snap chromium, which will not launch under the runner systemd cgroup (not a snap cgroup). Provision a real Chrome-for-Testing via @puppeteer/browsers on self-hosted; keep apt path for github-hosted. Harness already passes --no-sandbox.

…ad hang) Self-hosted runner provisions a fresh Chrome-for-Testing build via @puppeteer/browsers; under it page.goto(waitUntil:load) never fires the load event within 15s because a non-essential subresource (favicon) stays pending, failing Web-static verify on #439 only. The four dashboard scripts are synchronous head scripts (executed by DOMContentLoaded) and #defrag-canvas is gated by the explicit waitForSelector, so switching to domcontentloaded is render-correct and cannot regress the GitHub-hosted apt-chrome run on master.
…rk fallback Point the Windows job at the self-hosted runner (VM217, labels self-hosted/Windows/X64/c2pool-build) for internal-branch PRs and pushes; fork PRs fall back to GitHub-hosted windows-2022 so untrusted code never executes on the self-hosted box. Completes the self-hosted build fleet (Linux pending VM905 runner registration; macOS x86_64 already self-hosted via #100). Conan cache retained.
…) + sccache Repoint the macOS arm64 matrix lane to the self-hosted M4 Mac mini (label c2pool-mac-arm) on push and internal-branch PRs, with a GitHub-hosted fork fallback to macos-14 — same fork-gate shape as the Windows lane in this branch. Add sccache compiler launcher (persists across self-hosted runs; no-op-safe on the hosted fallback). Linux (VM905) leg held separately until that runner is registered.
… + ccache Apply the #439 fork-gate to every ubuntu-24.04 job: push/internal-branch PRs run on [self-hosted, Linux, X64, c2pool-build] (VM905, 32 cores); fork PRs fall back to GitHub-hosted ubuntu-24.04. Build stays -j$(nproc) (=32 on the box). Wire ccache as the C/C++ compiler launcher on the six C++ build lanes (linux, linux-asan, coin-bch, coin-bch-asan, qt, dgb-auxdoge) and add the ccache package to their apt lists so the binary is present on both self-hosted and fork-fallback runners. Completes the all-lane self-hosted switch (Linux+macOS+Windows).
VM217 (c2pool-windows-217) is a bare self-hosted runner with no build toolchain — no cmake, no MSVC/VS 2022, no SDK — so the Windows lane fails at configure. GitHub-hosted windows-2022 ships all of it. Keep Linux (8 lanes -> VM905) and macOS (M4/Intel) on the self-hosted fleet with the fork-gate; only the Windows job falls back to github-hosted. Follow-up PR will flip Windows back to the fork-gated self-hosted expr once VM217 has the VS 2022 Build Tools C++ workload + cmake + deps installed and builds c2pool clean.
VM905 now hosts 4 parallel self-hosted runners sharing one ccache. Cap per-job cmake/ctest parallelism at -j8 so 4 concurrent Linux jobs total 32 threads on the 32-core box instead of 4x nproc(32)=128 = thrash. macOS (sysctl hw.ncpu) and Windows (NUMBER_OF_PROCESSORS) lanes unchanged; ccache retained for cross-job warm hits.
VM905 runs 4 parallel self-hosted runners; concurrent apt-get install collided on /var/lib/dpkg/lock-frontend (exit 100), failing 6/7 Linux lanes. Core build deps are pre-provisioned by vm-fleet, so gate the 5 Install system dependencies steps to runner.environment == github-hosted (skip on self-hosted, still run on fork fallback). Chromium and Qt6 are not in the provisioned set, so keep their apt but flock-serialize across the 4 runners via /tmp/c2pool-apt.lock.
…romium Two self-hosted-environment gaps on the #439 switch (not code): - Linux x86_64 + ASan twin: reused workspace left a stale build_ci/ build_asan, so ctest re-included empty gtest_discover_tests POST_BUILD files -> Unknown CMake command gtest_discover_tests_impl, exit 8.

Provision a real Chrome-for-Testing via @puppeteer/browsers on self-hosted; keep apt path for github-hosted. Harness already passes --no-sandbox.
… (PRE_TEST exit-8 fix) The plain Linux x86_64 and AsAN+UBSan lanes failed at ctest with exit 8: CMake Error at build_*/test/test_dgb_subsidy[1]_include.cmake:6 Unknown CMake command "gtest_discover_tests_impl". preceded by "include() given empty file name (ignored)". include(GoogleTest) sets _GOOGLETEST_DISCOVER_TESTS_SCRIPT (the path to GoogleTestAddTests.cmake). It was at line ~176, AFTER the first three gtest_discover_tests() calls (test_dgb_subsidy/coinbase_value/utxo, all DISCOVERY_MODE PRE_TEST). In PRE_TEST the generated <tgt>[1]_include.cmake includes that script at ctest time to define gtest_discover_tests_impl; with the var unset the include path was empty and ctest aborted. The clean-build-dir step (8d05ef2) removed the cached _tests.cmake that had masked the broken else-branch, surfacing it on the first PRE_TEST target. Fix: hoist include(GoogleTest) to the top of the BUILD_TESTING block.
…ad hang) Self-hosted runner provisions a fresh Chrome-for-Testing build via @puppeteer/browsers; under it page.goto(waitUntil:load) never fires the load event within 15s because a non-essential subresource (favicon) stays pending, failing Web-static verify on #439 only. The four dashboard scripts are synchronous head scripts (executed by DOMContentLoaded) and #defrag-canvas is gated by the explicit waitForSelector, so switching to domcontentloaded is render-correct and cannot regress the GitHub-hosted apt-chrome run on master.
The self-hosted switch routed the sub-minute Web-static verify job onto the c2pool-build Linux runner along with the heavy C++ lanes. The puppeteer pixel-regression harness cannot complete page navigation there: page.goto times out at 15s under both load and domcontentloaded waitUntil, because the self-hosted runner environment never fires the navigation-complete event for dashboard.html. The job is green on ubuntu-24.04 and gains nothing from the 32-core box, so pin it back to GitHub-hosted. Dashboard-owned web-static assets and the visual harness are unchanged and not the cause.

VM217 (c2pool-windows-217) toolchain probe run 28679257030 is green across Python 3.12, Conan 2, CMake, Git and MSVC/VS 2022 C++ build tools. Route internal PRs/pushes to the self-hosted runner via the #439 fork-gate expr; fork PRs keep GitHub-hosted windows-2022. setup-python gated to github-hosted so VM217 uses its pre-provisioned interpreter. Last GitHub-hosted C++ lane.
