From 0ce9bc6da1fe32913a6482f7195953722f85fbe5 Mon Sep 17 00:00:00 2001 From: Victor Adossi Date: Wed, 14 Oct 2026 09:47:22 +0000 Subject: [PATCH 1/2] fix(p2-shim): avoid leaking Node globals in IO error declarations Declare IoError as a named class so the exported error namespace refers to its type instead of expanding the inherited constructor statics. This prevents generated declarations from referring to NodeJS.CallSite without declaring that dependency and lets the instantiation generics fixture compile.

Restore the missing localhost TLS fixtures using the existing jco-std test certificate and key, and correct stale test types so the package type check passes. Validation: 270 tests passed and 1 skipped; package build, TypeScript check, formatting, and lint passed.
