Highlights
- 1,362 points. Story URL points at Laya's publisher site, not TypeSafe.
- Commenters argue constrained choice from predefined options is an established pattern.
- OpenDecision's author says their project built on Jev-architecture research from a year earlier.
- A comment links arXiv 2503.23303 as prior art on the architecture Laya's author proposed.
Watch out
Point totals move. Architecture priority claims are commenters' interpretations, not court findings.
