+#+TITLE: Handoff from archangel — SSH_AUTH_SOCK routed through gpg-agent
+#+DATE: 2026-05-22
+
+* Why this is here
+
+This change was made from an *archangel* session (cross-project edit into
+archsetup's stow dotfiles), so it's logged here for archsetup's next session
+to review and commit. The trigger: from archangel I needed to SSH to the
+TrueNAS, but Claude's non-interactive Bash-tool shells couldn't reach any
+ssh-agent — =SSH_AUTH_SOCK= was unset in dotfiles, and ad-hoc =ssh-agent -s=
+instances live on random =/tmp= sockets that fresh shells can't find.
+
+* What changed (two stow files in dotfiles/common)
+
+1. =dotfiles/common/.config/environment.d/envvars.conf= — appended:
+   #+begin_example
+   SSH_AUTH_SOCK=${XDG_RUNTIME_DIR}/gnupg/S.gpg-agent.ssh
+   #+end_example
+   Systemd-native, cross-app, takes effect at next login.
+
+2. =dotfiles/common/.zshenv= — *new file*, exports the same socket. zsh
+   sources =.zshenv= on every invocation (incl. non-interactive tooling and
+   cron), so it works immediately without a re-login. Mirrors the
+   environment.d value.
+
+Also created the stow symlink =~/.zshenv -> code/archsetup/dotfiles/common/.zshenv=
+(relative, matching the existing =~/.zshrc= link style). If you re-run the
+stow/install step, confirm it keeps this link rather than clobbering it.
+
+* Why gpg-agent
+
+=~/.gnupg/gpg-agent.conf= already had =enable-ssh-support=, and gpg-agent
+serves a fixed socket. So this reuses an agent you already run rather than
+adding a new one. The =id_ed25519= key was loaded via =ssh-add= and persists
+in =~/.gnupg= across reboots. The only other =SSH_AUTH_SOCK= reference in the
+dotfiles is a commented-out gnome-keyring line in =.config/systemd/user/emacs.service=
+(=%t/keyring/ssh=) — inactive, no conflict, but worth reconciling if you ever
+want emacs on the same agent (point it at the gpg-agent socket instead).
+
+* Verification
+
+- Fresh =zsh -c= sources =.zshenv= → =SSH_AUTH_SOCK= set, =ssh-add -l= shows the key.
+- =ssh cjennings@truenas= (tailscale 100.67.22.65) connects with no inline prefix.
+
+* For archsetup's next session
+
+- Review + commit the two dotfile changes (envvars.conf, new .zshenv). Only
+  =todo.org= was dirty in archsetup before this; these two are the new edits.
+- Decide whether =.zshenv= should carry anything else you'd previously put in
+  an interactive-only file by mistake (it shouldn't produce output).
