Under the Vim preset, `:` opens a transient one-line ex overlay running a
fixed v1 table; ZZ runs :wq directly. Completes the last built child of the
T-403 cross-pane vim layer (T-405 part 2 gt/gT still open).
- ExLineController + parseExCommand grammar + editor-targeted executors
(lib/kernel/src/ex_line.dart); the overlay (lib/widgets/src/ex_line_overlay
.dart) reuses the quick-open chrome, mounts in the root_shell Stack, and
publishes the exline.open scope flag. Unknown commands flash + stay open;
with no active buffer every command no-ops (2026-06-13 decision).
- :q closes the active tab via editor.close on its id — the registry promotes
the next buffer and the split self-collapses on the last (2026-06-12
decision); :w/:wq/:x/ZZ save (+close) the active buffer.
- :e <path> seeds quick-open (new QuickOpenController.open(seed:)); :N adds the
editor.goto-line IPC/CLI verb (reuses _offsetForLine). Goto needs caret sync:
EditorController now handles editor.selection-changed and the editor view
moves the caret on a selection-only change.
- `:` and ZZ are typed intents; the editor matcher and PaneKeyNav now bubble
unhandled typed intents to the app-root Actions, so they fire from any focus.
vim.yaml binds `:`, ZZ (shift+z shift+z), and Esc-dismiss.
Tests: parser/controller/executors, editor.goto-line daemon tests,
selection-changed (controller + view), full overlay widget test. make test
green; analyze + format clean.
Also files T-441 (drop bold from the ticket-id card label) and T-442
(sub-agent renders as 3 cards instead of one bundle) under the T-276 UI epic.
