Checked on the Mac with a fake 60 s skew (`IGNEUM_APP_FAKE_SKEW=-60`): the banner, the node card, the blocked Start
button and the held miner all showed; with the real clock the HTTPS source read +0.4 s and the block source agreed.
## 4 October 2026, first machine on the Igneum Miner app: PC 2's RTX 5090 at 118 MH/s, via Setup.exe
the project lead's second PC (a clone of the first; the app's per-install machine id `1ccfe586` keeps its keys apart), installed from the
runner-built `Igneum-Miner-Setup-0.3.0.exe` (unsigned, SmartScreen "run anyway"), the one-click package: prebuilt NVRTC
worker, no toolchain on the machine. First attempt sat at "waiting for peer": the PC's clock was 62 s slow after a power cut
and `igneumd` rejected every relayed block ("the block timestamp is too far into the future"; the 10-s skew bound from the
hardened timestamp rule) and processed 0 blocks for 12 minutes with no visible reason. Clock set by hand; the node caught up
(46 blocks in the next 10 s at 12:27:53 BST), the 5090 started inside the app and ran at 117 to 119 MH/s with 34 accepted
blocks in the first minute, CPU re-check OK on every share, the integrated AMD chip at 3.3 MH/s beside it. Two defects
from the run, both fixed in the app the same hour: no clock-skew warning (now detected from the node's warning, block
timestamps and an HTTPS Date header; Start is blocked above 10 s), and the node card stayed on "syncing" after the late
catch-up while the miner was already accepted (state now re-derived every poll).
