A failed pass/gpg fetch (e.g. YubiKey not plugged in yet) used to pass
process output straight to string-trim, which signals instead of
returning nil on empty output, aborting the sentinel before
elfeed-feeds or elfeed-protocol-enable ran. That left elfeed-feeds nil
for the rest of the session with no visible error beyond a *Messages*
line, and every later elfeed-update silently had nothing to fetch.
Wrap the fetch in azos/elfeed-protocol-init-feeds so a failed attempt
can be retried interactively instead of requiring a full reload of the
elfeed-protocol feature.
gpg-agent may not have a cached passphrase yet when the top-level setq
runs at Emacs startup, so a cold agent makes 'pass' fail silently
(stderr redirected) and leaves lichess-token permanently empty for the
session. Retry the fetch right before each use instead of only once
at startup.
