First, the URL was `https://localhost:8080/imp' but simple-httpd serves plaintext on port 8080 -- the browser hit a TLS handshake against a non-TLS listener and the preview never rendered. Changed to `http://' and switched from `browse-url-generic' to plain `browse-url' so the user's default protocol handler picks the browser. Second, the function used to start the network listener as a side effect of opening a preview; that's split into a separate `cj/markdown-preview-server-start' command and `markdown-preview' now signals a `user-error' (with the recovery command in the message) when the server isn't running. - slack-config.el: wrap the `which-key-add-keymap-based-replacements' call in `with-eval-after-load 'which-key'. Matches the pattern other config modules use and means a slow / missing which-key load won't block requiring slack-config. - ai-vterm.el: pass the inner shell-command-string through `shell-quote-argument' before wrapping in the tmux invocation. The default value with embedded double quotes was safe under the prior literal-single-quote wrap, but a user-customized `cj/ai-vterm-agent-command' containing a single quote silently broke the shell parse. Two existing tests updated to tolerate the post-quote escape shape; new regression test asserts a single-quote-bearing custom command survives. - eshell-config.el: scope the `TERM=xterm-256color' override to eshell-spawned processes only via an `eshell-mode' hook that prepends to a buffer-local `process-environment'. The previous global `setenv' at config-time changed `TERM' for every subsequent `start-process' across the Emacs session, so any subprocess (not just eshell pipelines) inherited `xterm-256color' regardless of whether the receiver could interpret the escapes. 2026-05-10T08:25:35+00:00 Craig Jennings c@cjennings.net 2026-05-10T08:25:35+00:00 urn:sha1:b099c779343119ce40f2636469e118ec104002e0 The combined module had grown to 573 lines covering two unrelated subsystems with no shared state — the eshell shell-mode commands and the vterm/F12 toggle. The header even rendered this with two `;; ----` dividers. Split into two focused modules. eshell-config.el keeps the eshell user commands and package wiring (~170 lines). vterm-config.el keeps the vterm package, the tmux history capture command, the F12 toggle, and the C-; V keymap (~400 lines). Update init.el to require both, point the four vterm test files at vterm-config, and refresh the cross-module commentary in cj-window-geometry.el and cj-window-toggle.el. No behavior change. Full test suite green; validate-modules clean.
