+** Elfeed Nextcloud News Sync
+
+[[https://github.com/fasheng/elfeed-protocol][elfeed-protocol]] adds an =owncloud+= protocol that speaks the
+ownCloud News API, which the Nextcloud News app also implements, so
+it syncs elfeed's feed list and read/unread state with the Nextcloud
+News app instead of just reading a local feed list one-way.
+
+Reuses the same =zakobar.com= pass entry as the CalDAV sync above,
+since it's the same Nextcloud account. =shell-command-to-string=
+merges stderr into its return value, so stderr is redirected away to
+keep a stray gpg/pass warning from getting concatenated onto the
+password.
+
+As of elfeed-protocol 1.0.0 (paired with elfeed >= 4.0.0), the
+credentials go directly on =elfeed-feeds= — the older
+=elfeed-protocol-feeds= variable is dead: setting it only logs a
+deprecation warning, and =elfeed-feeds= ends up with the bare URL
+and no =:password=, so requests silently authenticate with an empty
+password and nothing ever lands in the db.
+

+** Elfeed Full Article Fetch
+
+Many feeds only publish a short excerpt. elfeed >= 4.0 has built-in
+commands for this — =f= (=elfeed-show-fetch-link=) fetches the
+linked page and appends it to the show buffer, =R=
+(=elfeed-show-readable=) strips the fetched page down to
+article text via eww's readability scorer — and both can run
+automatically via =elfeed-show-update-hook=, gated on a feed's
+=:fetch-link=/=:readable= metadata.
+
+That gating keys off an exact match on the feed's URL/id in
+=elfeed-feeds=, which breaks for ownCloud/Nextcloud subfeeds:
+elfeed-protocol synthesizes a per-subfeed id of the form
+=<host-url>::<subfeed-url>= that never appears in =elfeed-feeds=
+(only the bare host URL does), so the metadata lookup always misses
+and the stock hooks never fire. Replacing them with unconditional
+versions makes full-text + readable-mode the default for every
+entry instead.
+
+#+begin_src emacs-lisp
+(defun azos/elfeed-show-auto-readable ()
+  "Like `elfeed-show-auto-readable', but unconditional."
+  (unless (local-variable-p 'elfeed-transform-html-functions)

+
+** Lichess
+
+=lichess.org= in pass already holds the website login password, and
+lichess.el's =auth-source-pass= lookup resolves by bare hostname, so
+the API token can't live under that same entry without colliding.
+Store it separately under =lichess.org/token= (=pass insert
+lichess.org/token=) and set the =lichess-token= variable directly —
+=lichess-token= (the function) checks this variable before falling
+back to =auth-source=, so this takes precedence without disturbing
+the existing =lichess.org= entry or its consumers (e.g. browserpass).
+
+=shell-command-to-string= merges stderr into its return value, so any
+gpg/pass warning on stderr (e.g. an unsafe-permissions notice) would
+otherwise get concatenated onto the token and break auth silently.
+Redirect stderr away so only the token itself is ever captured.
