Fettle 1.0.3

Fixes from two independent audits: safer downloads, better disk and Windows verdicts, and more privacy in shared reports.

• Fettle now starts on a PC without the Microsoft Visual C++ runtime: both downloads bring the files it needs. It loads Windows' own files only from Windows, so a file left beside fettle.exe can't load into it, not even during a Deep check.
• A drive that reports sectors it can't read or repair is now marked ACT. Hard drives warn above 55 °C, Samsung SATA SSDs show their temperature, and Fettle reads only a drive's SMART table, so nothing after it can pass for a warning.
• "In fine fettle" now needs every section checked, including your version of Windows.
• On Windows 10, Extended Security Updates enrolment is read from the Windows build, not from when an update was installed, and a PC with no security update since November 2025 is marked ACT.
• Reports also hide your full name, email addresses, the company domain, IPv6 addresses and network server names.
• Share links: each visitor gets 20 wrong passwords a day, a pass is renewed when used, and the server limits uploads and views per address.
• Two Fettle windows no longer lose each other's shared links, the update check backs off after a failure, and uninstalling for all users can remove every account's data.
