Arc 0.1.18 — Reliable Play, fresh ratings

Arc 0.1.18 improves Play reliability and keeps your ratings up to date.

• Fix Windows executable-path compatibility affecting games such as Sekiro. Canonical file validation is retained; the child process receives an ordinary Windows path when it identifies the same executable.
• Launch installed Steam games through their verified Steam App ID. Supported local Epic, Riot, EA, Ubisoft, Battle.net, Rockstar and GOG registrations use their owning clients; Knight Online uses its own launcher.
• Follow game processes across supported store-client handoffs without counting the shared client as gameplay.
• Refresh verified Steam and Metacritic ratings every 72 hours, including checks after resume or reconnect. Keep saved scores offline and retry failed updates later.
• Update the optional SCSKiller compatibility build to 1.2.5-arc.1 with matching upstream native tools. SCSKiller remains a separate installation; build/connect instructions are in the compatibility guide.
• Display the actual package version in Arc's footer.

The unsigned Windows x64 NSIS installer is about 3.5 MiB. Existing library records, preferences and artwork are retained. WebView2 is provided by Windows or the installer bootstrapper.

Local validation passed 77 frontend tests, 86 Rust tests, strict Clippy, TypeScript/Vite bundling, SQLite checks and Windows packaging. The separate SCSKiller build passed 706 synthetic regressions. Sekiro's corrected native launch was confirmed by the user; other store routes have synthetic and installation-plan coverage, with live gameplay coverage described in validation notes.

Requiem recording remains unavailable where upstream detects the DLSS/NVIDIA DirectX 12 load-order conflict. Arc retains this guard. Shader support depends on the game's available pipeline data; standalone and console sessions still track the directly launched process.

The maintained compatibility guide/build recipe follows upstream's rebuilt v1.2.5 history. Its current source pin has the same complete source tree as the tested build; Arc's installer and checksum are unchanged.
