Test	ea61ded4af	fix: use type-only import for DecorationSet (verbatimModuleSyntax) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>	2026-03-03 19:40:39 +01:00
Test	3a623d48bb	feat: replace raw editor textarea with CodeMirror 6 Adds line numbers, current line highlight, and syntax highlighting (YAML frontmatter keys/values, --- delimiters, markdown headings). Extracted useCodeMirror hook and frontmatterHighlight extension. Preserves wikilink autocomplete, Cmd+S save, and Escape dismiss.

Test	3fcb06396a	fix: use git ls-files --unmerged for reliable conflict detection git diff --name-only --diff-filter=U only works during an active merge (while MERGE_HEAD exists). When the vault has stale conflict state — e.g. after a reboot — git diff returns empty, causing conflictFiles=[] and making the StatusBar click handler, command palette entry, and conflict resolver modal all non-functional. Switch to git ls-files --unmerged which reads unmerged index entries directly and works regardless of MERGE_HEAD state.

Test	17eeac75cd	fix: open newly created theme in editor after New Theme command After createTheme(), the theme file was created and the sidebar navigated to the Theme section, but the note was never opened in the editor. Now captures the returned path and opens it via handleSelectNote. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>	2026-03-03 19:29:32 +01:00

Test	c3fa296b99	refactor: remove AI model indicator from status bar Remove the hardcoded "Claude Sonnet 4" stub label and unused Sparkles import — no model picker is planned at this stage. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>	2026-03-03 14:57:20 +01:00
Test	6370b66e05	fix: handle Escape at panel level and manage focus across active states Move Escape handler from input onKeyDown to a window-level listener scoped to the panel, so it works even when input is disabled during AI response. When agent is active, focus transfers to the panel container; when idle, focus returns to the input. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>	2026-03-03 14:34:18 +01:00
Test	1ec27dd264	fix: auto-focus AI Chat input on panel open and close on Escape When AI Chat panel mounts (via Cmd+I), the input field now receives focus automatically so users can type immediately without clicking. Pressing Escape in the input closes the panel. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>	2026-03-03 14:30:12 +01:00
Test	10e6d7b366	fix: handle EADDRINUSE in MCP server ws-bridge — allow Claude Code to start when port is taken When Claude CLI starts the Laputa MCP server, it crashed immediately because startUiBridge() tried to bind port 9711 which is already held by the running Laputa app. The unhandled EADDRINUSE error killed the process, making all Laputa MCP tools unavailable to Claude Code in AI Chat. Fix: - Make startUiBridge() async, return Promise<WebSocketServer\|null> - Handle 'error' event on HTTP server: EADDRINUSE resolves to null instead of crashing - Guard broadcastUiAction() with 'if (!uiBridge) return' for graceful no-op - In ws-bridge.js main: chain startUiBridge().then(() => startBridge()) All vault tools (read/write/search) now work via stdio MCP when port is busy.	2026-03-03 13:22:28 +01:00
