Restores the kernel-level isolation the pre-cutover ttyd-session.sh had,
but keeps the multi-session lobby UX:
- ttyd.service gets `-H X-authentik-username` back. `tmux-attach.sh` reads
$TTYD_USER, looks up the local part in /etc/ttyd-user-map, denies the
connection (no fallback to wizard) if there's no mapping, otherwise
`sudo -n -H -u <os_user> tmux …`. Each Authentik identity → its own
Unix user → its own `/tmp/tmux-<uid>/default` socket.
- tmux-api scopes every request to the same OS user via the same header.
Adds /whoami so the lobby HTML can preflight access and render
"logged in as <os_user> (<authentik>)" instead of leaving the user to
discover the deny via a reconnect loop.
- Commits /etc/ttyd-user-map and the matching /etc/sudoers.d/ttyd-users
fragment under files/devvm/ so future operators see one canonical
source of truth. Current mappings: vbarzin → wizard, emil.barzin → emo.
Adding a user is now: append a line to ttyd-user-map + a NOPASSWD
sudoers line + `useradd -m`. README walks through it.
No Terraform changes — this is all DevVM-side + lobby JS.
Promotes the staged multi-session UX from term.viktorbarzin.me to the
primary terminal.viktorbarzin.me hostname. `ttyd.service` on the DevVM
moves to the same ExecStart that `ttyd-multi.service` was running:
`/usr/local/bin/ttyd -W -a -t enableClipboard=true -I
/usr/local/share/ttyd/index.html -p 7681 /usr/local/bin/tmux-attach.sh`.
The lobby HTML supersedes the old per-user-attach index.html
(ttyd-session.sh wrapper retired alongside).
Terraform: retires the `terminal-multi` Service+Endpoints and the
term.viktorbarzin.me ingress (Cloudflare DNS record for `term` is
released by module deletion). The tmux-api Service+Endpoints stay, but
its IngressRoute now matches terminal.viktorbarzin.me — same path-prefix
specificity wins against the catch-all ingress.
DevVM follow-up (applied manually as before — see files/devvm/README.md):
restart ttyd to pick up the new unit, stop+disable ttyd-multi.service.
