 - **Session 155**: Core Commentary Feature — unified comment toggling into `src/core/comment.rs` (46+ language table, two-pass algorithm, override chain), `:Comment`/`:Commentary` commands, `vimcode.set_comment_style()` plugin API, Ctrl+/ fix for GTK+TUI, VSCode Ctrl+Q/F10, 19+31 tests

 - **Session 153**: Richer Lua Plugin API + VimCode Commentary + User Keymaps — Extended plugin API (cursor write, settings access, state queries, buffer insert/delete, register write, 7 new autocmd events, `set_mode()` refactor, visual/command keymap fallbacks); VimCode Commentary bundled extension (gcc/gc/`:Commentary`, 40+ language comment strings, undo support); plugin `set_lines` undo fix; user-configurable keymaps in settings.json (`"mode keys :command"` format, multi-key sequences, override built-in keys, `{count}` substitution); 22 + 17 + 13 = 52 new tests (2801 total)

 ## Recent Work
 
+**Session 156 — IDE Polish: Indent Guides, Bracket Matching, Auto-Pairs (2937 tests):**
+Three visual/editing polish features: (1) **Indent guides** — vertical `│` lines at each tabstop in TUI, thin Cairo lines in GTK; controlled by `indent_guides` setting (default on); active guide at cursor scope highlighted brighter; blank lines bridge surrounding indent levels. (2) **Bracket pair highlighting** — when cursor is on `(){}[]`, both brackets get a distinct background (`bracket_match_bg` theme color); `bracket_match` field on Engine updated at end of `handle_key()`; `match_brackets` setting (default on). (3) **Auto-close brackets/quotes** — typing `([{"'\`` in Insert mode inserts matching closer with cursor between; typing closer when next char matches skips over it; Backspace between a pair deletes both; smart context for quotes (only pair after whitespace/brackets/BOL); `auto_pairs` setting (default on). All three features have `:set` toggle support, settings UI entries, and theme colors across all 4 built-in themes. 29 integration tests in `tests/ide_polish.rs`.
+
 **Session 155 — Core Commentary Feature (2908 tests):**
 Unified comment toggling from three separate implementations (Lua plugin, Rust `toggle_comment_range()`, Rust `vscode_toggle_line_comment()`) into a single core module `src/core/comment.rs`. New `CommentStyle`/`CommentStyleOwned` types, `comment_style_for_language()` table covering 46+ languages (including block comments for HTML/CSS/XML), two-pass `compute_toggle_edits()` algorithm, `resolve_comment_style()` override chain (plugin → extension manifest → built-in → fallback `#`). Added `CommentConfig` to `ExtensionManifest` in `extensions.rs`. New `toggle_comment()` method on Engine replaces old `toggle_comment_range()` and `vscode_toggle_line_comment()`. Rewired `gcc`, visual `gc`, and VSCode `Ctrl+/` to use the new core. Added `:Comment` command (`:Commentary` kept as alias). Plugin API: `vimcode.set_comment_style(lang_id, {line, block_open, block_close})`. Fixed Ctrl+/ in GTK (key name `"slash"` not `"/"`) and TUI (crossterm byte 0x1F → `Char('7')` mapping). VSCode mode: added Ctrl+Q quit, F10 menu toggle, menu visible by default. 19 unit tests in `comment.rs`, 31 integration tests in `tests/commentary.rs`.
