The console-window class (the project lead, 5 October 2026: "Windows Command Processor" windows on PC 1 whenever a remote job runs).
Measured on PC 1 (ae432dc7, Windows 11 Pro 26200, default terminal "Let Windows decide" = Windows Terminal 1.24) with
tools/windows/console-watch.ps1 (job run-20261005-182528): no child a job script starts from the app's headless
console opens a window (powershell, cmd, query, curl, nvidia-smi, wsl --status, a distro, interop cmd and powershell,
powershell -WindowStyle Hidden: 0 windows each); Start-Process in a new console opens a Terminal window (the known-failed
case: 2 windows), the same with -WindowStyle Hidden opens none (the known-finished case). The elevated path
(Start-Process -Verb RunAs -WindowStyle Hidden through the AppInfo service) is the one road left; its watcher
(console-watch-elevated.ps1, job run-20261005-184610) was cancelled at the UAC prompt.
- platform.rs: elevated_ps_line + elevated_command build the one PowerShell line every elevated launch uses (the NVIDIA
power cap, the sweep helper, the clock sync, an elevated remote job), -WindowStyle Hidden by construction; unit
tests on the line, the quoting and the Command.
- jobrun.rs: the elevated job path uses it; the relaunch helper's Start-Process carries the reason it has no
-WindowStyle Hidden (igneum-app.exe is a windows-subsystem program).
- tools/ci/windows-spawn-check.mjs (+ ci.yml): fails when a Command::new in app/igneum-app/src is not quieted,
a creation_flags is not CREATE_NO_WINDOW alone, a Start-Process the Rust code writes lacks -WindowStyle Hidden or
-NoNewWindow, or host.cpp spawns without CREATE_NO_WINDOW / SW_HIDE; self-test on known-good and known-bad samples.
- tools/windows/console-watch.ps1, console-watch-bg.ps1, console-watch-elevated.ps1: the watchers (run jobs).

PC 1, 6 October 2026 06:58:47Z: the app came up after the 0.3.11 publish, had the installer verified 44 s
later and sat on "installs at the next safe moment" with its slot at minute 35; the project lead pressed Install now at
07:00:48Z. The slot staggers a fleet through a NEW publish; a machine that was off through the publish has
nothing to stagger. Now: published_at + 3,600 s <= engine start => slot_ok, logged once. The other safe-moment
guards (node synced, miner idle, boundary, network drop) are unchanged. manifest::unix_from_rfc3339 with tests.
For 0.3.12.

the project lead, 6 October 2026: on PC 1 the integrated card sat between the 5090 and the 9070 XT. The list now shows
usable cards first, ordered by the measured rate since the start in 5 MH/s buckets (no flicker), discrete,
external and Apple before integrated, then memory; removed and unusable cards last; ties keep the detection
order. The row signature follows the order, so a reorder re-renders. Three UI tests. For 0.3.12.

One prover at 2.2% coverage never had 8 consecutive proven blocks (C47, 6 October 2026); claiming whole segments makes it complete about 1 segment in 75 instead of none. The choice is deterministic per key (FNV of first block and key hash) over the untouched whole segments inside their deadline by a margin (240 DAA or 1.5x the last segment's time); the per-block path stays as the fallback. Unit tests for the grid, the grouping, the margin, the attempted set and the per-key order; 120 app tests, 8 core and 9 host tests pass.

serde_json's to_value refuses a u128 over u64::MAX (18.45 IGN) and state_json turned the error into json!({}). A paid shard is 1.23 IGN on average, so a proving machine's dashboard went blank about 15 paid shards after every app start. Unit test over the boundary; 114 app tests pass.

cargo test --release -p igneum-app under the build lock: 113 + 27 + 8 passed, 0 failed (the prepare_packs_tests,
resume_tests and provedefault tests among them).

The known-failed case, from PC 2's 0.3.9 log (run win-1ccfe586-20261005-200114): 1791234223 pause -> 'stopping the
miners (paused)' (every slot's restart_at cleared, the 5090 'off'); 1791235511 '[ok] mining resumed'; then
'0.00 MH/s, waiting' at every 30-s status line until the 0.3.10 restart at 21:49:41Z. Cause: Cmd::Resume re-armed
only slots whose watchdog said faulted; the 5090's slot was healthy and stopped, so nothing restarted it. The test
the_pc2_resume_of_21_25_11z_restarts_under_the_new_rule_and_not_the_old encodes that slot (faulted false, live
false): the old rule returns [] (the defect), the new rule [0]. cargo test -p igneum-app resume: 3 passed;
provedefault: 6 passed.

the project lead, 5 October 2026, 22:45 BST: "make sure we have ember tuning every single card for efficiency out of the box, the
more data = the better the tune, make an awesome system." Built on lever 3 (docs/plans/miner-eff.md), lever 2's signed
tuning section (docs/design/miner-tuning.md), the AMD telemetry helper (423936b, its --tune/--set-gmax/--set-plimit/
--reset contract) and the Power control switch (057f0ec). Design, data flow, tiers and the privacy line:
docs/plans/ember-tune.md.
- src/ember.rs (new): two knobs per card (power limit %, core clock cap MHz; memory clock never touched), the full plan
(power ladder 100..50%, then the clock ladder 90..60% at the chosen power), the confirm plan (the fleet prior and one
neighbour), the baseline plan (measure only), the marks (faulted, hot, memory_clock_dropped, unapplied, no_readings),
the choice (best MH/W within 1% of the top rate, then rate, then draw), the fleet record (a hash of the install id,
no address), the prior lookup and the kill switch (tuning.ember), the state machine on a fake clock. 9 unit tests.
- engine.rs: tick_sweep schedules every NVIDIA, AMD and Apple card (120 s steady, 600 s to the boundary, no job hold,
no pause, weekly, again after a driver major or program-class change, never under the manifest kill switch); the
probe (nvidia-smi clocks.max.gr + driver_version and the direct/helper mode; igneum-gpu-telemetry --tune for AMD);
tune_apply (nvidia-smi -pl / -lgc 0,<MHz> / -rgc directly or through the helper; the AMD helper per request);
Cmd::TuneProbe, Cmd::TuneSet; faults from rejected and mismatched hashes mark the step; the TUNE lines and the TUNE
{json} record, uploaded with the log; the Tuned line on the card state. The NVIDIA helper starts only with Power
control on: the --sweep job never counts as permission (no prompt on a PC with nobody there).
- sweep.rs: the helper protocol gains lgc/rgc (clock cap and reset) and resets the clocks after 20 idle minutes.
- state.rs, config.rs: the tune fields (clock cap, driver, class, source, the Tuned line); the nvidia-smi telemetry
query carries clocks.gr and clocks.mem; the AMD sample line's plimit_pct and gmax_mhz are parsed.
- ui: "Tuned: X MH/s at Y W (Z MH/W)" with the point, the source and when; measure-only cards say why; the Ember Tune
switch; tune-line.test.mjs.
- relay/lib/ember.mjs + relay/test/ember.test.mjs: the aggregation per (card model | driver major | program class):
median point, MH/W, spread, samples, machines; five samples converge, an outlier does not move the median, baselines
make no prior, de-duplication, the manifest merge keeps lever 2's cards. api/console.mjs fn=tuning and
tools/console.mjs tuning; tools/tuning.mjs --priors [--write tuning.json] [--site] [--tuning-off].
- site: the fleet priors table on /miners (site/miner-priors.json), the lever text.
- relay/playbooks/ember-tune-pc1.ps1: the PC 1 run (second engine with --sweep from a scratch copy of the install).
Measured tonight: see the bench log entry that follows the PC 1 run. The 9070 XT left PC 1's bus at 20:40 UTC and the
5090 needs the administrator prompt the project lead cannot answer asleep, so tonight's PC 1 run is the baseline plan on the 5090
through the whole pipeline; the two-knob tune on both cards is owed.
