From 7d1b5225e053bd870bfd755a99396e48b58e36b6 Mon Sep 17 00:00:00 2001 From: Claude Date: Mon, 29 Jun 2026 23:25:35 +0000 Subject: [PATCH 1/4] feat(view): unwrap Readplace self-URLs when saving MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Saving a Readplace reader URL (e.g. /view/fagnerbrack.com/x) now saves the underlying original article (https://fagnerbrack.com/x) rather than the self-referential wrapper. Without this, a /view/... URL pasted into any save surface was stored verbatim, producing a double-nested article that crawls Readplace as a third-party site. The fix is a pure URL→URL preparser composed into the injected validateSaveableUrl at each composition root, so it runs before the stub row is written and applies to every client (web, extension, iOS, MCP, import) with no per-route code. It recognises /view// and /view/?url= shapes, recursively collapses nesting, and matches only the deployment's own host. Because /view rendering also routes through validateSaveableUrl, visiting a nested self-URL now resolves to the real article too.
