codemirror-vim matches special keys only in their exact canonical spelling, so rc mappings written for Vim/IdeaVim such as `inoremap jk <esc>` never fired. The rc parser now canonicalizes `<...>` key names on both sides of a mapping: any case and the usual aliases (Esc, CR/Enter/Return, BS, Del, Ins, Space, Tab, Bar, Bslash, arrows, Home/End, PageUp/PageDown, F1-F12), modifier prefixes in any case and order (C-/S-/A-/M-, D- as Command), `<lt>` kept literal on the right-hand side, Ex mappings ending in <Enter>/<Return>, and leader values containing `$&`. Unknown tokens are left untouched.

Plugin API 1.4: grants for unencrypted HTTP, local sockets, IDE commands and owned database sources; window status items, output channels, content tabs, editor selections, decorations, search, Problems and VCS reads; runs, keyed terminals with exit events, plugin run targets, dynamic run configurations and test parsers; language features, injections, snippets and menu locations; plugin MCP tools on the built-in server; four official API examples. Released 1.3 plugins keep working.
codemirror-vim labels its own edits input.type.compose to group them for undo; the Normal-mode IME extender matched that label alone and marked them transient, so the document model and saves missed them. Only transactions of a view with an IME composition in progress are transient now.
codemirror-vim only discards single-character IME commits in Normal mode, so multi-character commits (Chinese pinyin, Japanese conversions) were written into the document and could replace the selection. In Normal/Visual mode the composition now renders as usual and its whole span is restored when it ends; an ASCII single-character commit (dead keys) is replayed as a Vim key. Composition changes are marked transientChange: they stay out of undo history, the document model, the backend and other split panes. Insert/Replace mode is unchanged.

Built-in Vim emulation on @replit/codemirror-vim (approved dependency), modelled on IdeaVim: `vim.toggle` (Tools › Vim, status widget, Settings › Editor › Vim), mode widget (NORMAL / INSERT / VISUAL / V-LINE / V-BLOCK / REPLACE), IdeaVim-style shortcut conflict handlers (Vim / IDE per key) through a generic `registerKeyClaim()` in the keymap dispatcher, Escape closing popups first, a safe subset of ~/.openideavimrc / ~/.ideavimrc (set, map variants, mapleader, :action / <Action>()), Ex commands :w :wa :q :qa :wq :x :action. Covers file editors, diff editable side and merge result via a new `embeddedEditorExtensions` extension point.
Verified in the app on macOS: motions/operators, i/Esc/V mode widget, :w saves, Ctrl+R redoes in Vim without running Run, toggling off restores plain editing. Not verified on Windows/Linux.
