**Top 5 Stories (ranked by AI/Startup relevance)**

**#1. JSON Formatter Chrome Plugin Now Closed and Injecting Adware** — Score: 5/10
The popular JSON Formatter Chrome extension has been archived by its creator, who is pivoting to a closed-source, commercial API-browsing tool with premium features. Despite the alarming HN title suggesting adware injection, the repo shows no evidence of malware — it appears to be a straightforward open-to-commercial transition. A final open-source "Classic" version remains on the Chrome Web Store, and the codebase is still available for forking.

**#2. Industrial Design Files for Keychron Keyboards and Mice** — Score: 4/10
Keychron has open-sourced production-grade CAD files (STEP, DXF, DWG, PDF) for 88 device models spanning keyboards, Hall Effect boards, and mice — over 686 design files in total. The license allows personal, educational, and commercial use for compatible accessories, but prohibits manufacturing replicas. This is a significant move in the open hardware space, enabling a maker ecosystem around one of the most popular mechanical keyboard brands.

**#3. WireGuard Makes New Windows Release Following Microsoft Signing Resolution** — Score: 3/10
WireGuardNT v0.11 and WireGuard for Windows v0.6 drop after an extended development hiatus, bringing improved IPv4 MTU handling, streamlined architecture, and updated toolchains. The release was briefly delayed when WireGuard's developer account was suspended during Microsoft's kernel driver signing process, but this was resolved within a day after public attention — a bureaucratic glitch, not a conspiracy. The update is available via the built-in updater or direct download.

**#4. 1D Chess** — Score: 2/10
A playable browser implementation of one-dimensional chess, a puzzle variant originally proposed by Martin Gardner in his 1980 Scientific American column. The game strips chess down to a single line with only Kings, Knights, and Rooks, challenging players to find forced checkmate strategies. It's an elegant coding project that turns a decades-old mathematical curiosity into an interactive experience.
