From f07b6e497e7b4ee8764472e433f5bff1f3776ed7 Mon Sep 17 00:00:00 2001 From: giles Date: Wed, 6 May 2026 08:30:46 +0000 Subject: [PATCH] prolog: Hyperscript bridge (+19) pl-hs-query, pl-hs-predicate/1,2,3, pl-hs-install in hs-bridge.sx. No parser/compiler changes: Hyperscript already compiles `when allowed(user, action)` to (allowed user action). Total 590/590.
