ios-share-txt-stuck-supportstext	iOS sharing a .txt to Readest hung the share sheet; Share Extension NSExtensionActivationSupportsText captured plain-text files	node_type type originSessionId memory project 445ce295-90f6-4ed2-8227-e25b1e0a876d

Sharing a .txt file to Readest via the iOS share sheet got stuck, while EPUB/PDF worked. Root cause: the Share Extension (article-URL clipper, added #4256/#4267) wrongly activated for .txt. FIXED, PR #4917 merged (fix/ios-share-txt-stuck).

• ShareViewController.swift only ever extracts an http(s) URL. Its activation rule (project.yml) had NSExtensionActivationSupportsWebURLWithMaxCount: 1 and NSExtensionActivationSupportsText: true.
• A .txt is UTI public.plain-text, which conforms to public.text → satisfies SupportsText → the URL-only clipper activates for a file it can't handle → sheet hangs (for a file-backed provider loadItem(public.plain-text) returns a file URL, so loadText's as? String/as? Data both fail → no URL → neither completes nor cleanly cancels).
• EPUB (org.idpf.epub-container) / PDF (com.adobe.pdf) conform to neither text nor web-URL, so they never match the extension and take the main app CFBundleDocumentTypes "Copy to Readest" open-in-place path (Readest_iOS/Info.plist), which imports via useOpenWithBooks.ts → importBook (format-agnostic; txt→epub via TxtToEpubConverter). .txt is ALSO declared there, so it imports fine once the extension stops stealing it.

Fix (option A): remove NSExtensionActivationSupportsText: true; keep web-URL only. Safari/Chrome "share page" still sends public.url, so article clipping is preserved. Only regression: sharing a raw text selection containing a link no longer triggers the extension (minor).

Source-of-truth gotcha: src-tauri/gen/apple/project.yml is the xcodegen source; Tauri's iOS CLI runs xcodegen at build time (tauri-cli/src/mobile/ios/project.rs) and REGENERATES each target's Info.plist from it. The committed ShareExtension/Info.plist is a generated artifact marked skip-worktree (git ls-files -v → S) — local edits to it are invisible to git and it stays stale at HEAD. So: fix project.yml ONLY; a test asserting on the committed plist would pass locally but FAIL on a fresh CI checkout. Regression test lives at src/__tests__/ios/share-extension-activation-rule.test.ts (asserts on project.yml, strips # comments first since the warning comment names the key). Test precedent: src/__tests__/android/*declarations*.test.ts read native config via resolve(process.cwd(), 'src-tauri/...').
