From 9babeafa2403a169ba373d4f372ad0e72fde920b Mon Sep 17 00:00:00 2001 From: Kit Langton Date: Fri, 17 Apr 2026 16:27:09 -0400 Subject: [PATCH] feat(effect-zod): translate Schema.check filters into zod .superRefine Extends util/effect-zod so the walker reads ast.checks on every node and applies each Filter / FilterGroup as a .superRefine on the derived Zod schema. The filter's returned message (or message annotation) is passed through as the refinement error message. Moves the existing ConfigLSP.Info 'custom LSP servers require extensions' validation from the derived Zod layer onto the Effect Schema itself via Schema.makeFilter and .check(...). The refinement now runs in BOTH validation paths: - Schema.decodeUnknownSync(ConfigLSP.Info) (Effect layer) - ConfigLSP.Info.zod.parse(...) (derived Zod) Tests: - test/util/effect-zod.test.ts: 5 new cases covering filter message returns, undefined passes, annotations.message fallback, and cross-field record checks - test/config/lsp.test.ts: 9 cases covering builtin/custom/disabled LSP entries across both decode paths Follow-up to #23167 (lsp leaf migration) which only enforced the refinement on the zod-side.
