Org-mode occasionally opens files automatically, for instance, when
inserting or opening ID links, or during certain searches. I need to
determine if a buffer was opened programmatically or manually by the user
within the startup hooks. This distinction is important because, e.g., I
want to automatically preview all LaTeX fragments if the buffer was opened
by the user, but not if it was opened programmatically.
PS: Please use reply-to-all.

AFAIK, there is no reliable way to do this.
You may play around with `find-file-hook'. See `org-with-file-buffer'
macro in org-macs.el (on main).

A heuristic I use is to check if the window is visible. It's not
perfect but good enough for my use (which includes previewing LaTeX
fragments):
(defun my/latex-preview-maybe ()
(when (window-live-p (get-buffer-window (current-buffer)))
(org-latex-preview 'buffer)
(org-latex-preview-auto-mode 1)))
(add-hook 'org-mode-hook #'my/latex-preview-maybe)

`find-file-hook` seems not to have false negatives, at least. Using
`(window-live-p (get-buffer-window (current-buffer) 'visible))` has false
negatives for me (i.e., it returns nil for some interactive buffers).
Thanks, everyone.

Be careful and limit automatic preview to files you created yourself.
Doing so for an arbitrary file downloaded from net might cause huge
amount of garbage files in /tmp.
Emacs-29.3 includes a fix for CVE-2024-30204 that is specific for email
attachment inline preview. When a regular file is opened, weird LaTeX
code inside still may be executed. There is no general way to determine
if specific file should be treated as trusted.
