Release 0.3.0

[geeooff]

The release commit for 0.3.0, and a fix to the installer found while preparing it.

What 0.3.0 carries — its CHANGELOG.md section

The configuration applies as you save it, a broken one says so, the games you marked yourself in the Game Bar are followed too, and the watcher costs a twelfth of what it did at rest.

• Added: the configuration reloads within a second of a save, a game in progress undisturbed (Lot 9); a broken configuration shows as a red icon with a notification, and its end is said too; games marked by hand with Remember this is a game are detected from their launch or from a tick mid-game; at start, the log names the marked games Microsoft's own list now knows (Lot 15).
• Changed: 0.026 % of a core at rest against 0.324 % for 0.2.0, measured; the watcher starts whatever the file says instead of exiting 3 or 4 at logon — the contract change that makes this a minor release in 0.x.
• Fixed: a misspelt log_level used to leave a log with nothing but errors in it.

The two commits

• Release 0.3.0 — version = "0.3.0", the [Unreleased] section turned into ## [0.3.0] - 2026-09-23 with a summary line, a stray blank line and an imprecise sentence fixed, [Unreleased] empty again, the compare links moved on.
• Build the installer's cabinet in one piece, and refuse one that is not — the local build.ps1 release said release OK with an 88 KB installer: makecab's default disk is a 1.44 MB floppy, the executables had grown past it once compressed (1,476,966 bytes), and with a fixed cabinet name the second cabinet of the spanned set overwrote the first. The File table still listed four files, which is all the 102 evaluators check. Published, the installer would have failed on every machine — first on the update meant to close Lot 13. scripts/msi.ps1 now sets MaxDiskSize=0 and refuses a cabinet that expand -D does not show holding every file, or a build that left more than one. Recorded in docs/design/08-distribution.md.

Verified locally

build.ps1 release at 9acf017: checklist green, binaries stamped 0.3.0 (9acf0173), the changelog section found, 102 evaluators clean, installer 1.5 MB. An administrative extraction of the installer (msiexec /a, nothing installed) produced the four files at their exact sizes, and the extracted executable answers 0.3.0 (9acf0173).

After the merge

Tag v0.3.0 on the merge commit — on approval — and the workflow publishes. Then Lot 13 closes on the first update from a genuine 0.2.0 through the menu, on both machines.
