Upstream module dropped host-specific comments for its public repo, so the
context that matters here — gateway fronting, why this vhost stays off the
tailscale address group where opencode lives, and the exposure check script —
moves into the copy's header where it belongs.
Functional changes from upstream: the container now runs as uid 10001 and the
unit chowns the bind-mounted cache before start (without it, cache files left
by the earlier root container are unreadable and every cached actor 500s).

Sync of the canonical module. The atproto vhost listens on 0.0.0.0 only, so it
never shares an address group with oc.commoninternet.net (which is the default
server on 100.84.190.30:80 and has no auth in front of it). A new
public-default-reject vhost owns the public addresses — return 444 on 80,
ssl_reject_handshake on 443 — so unmatched, absent or spoofed Host headers from
the internet get nothing, now and after any future vhost is added.
The tailnet is untouched: oc.commoninternet.net still serves opencode there.
Verified with tools/check-exposure.sh in the project repo — 9/9 ok.

Sync of the canonical module in the project repo. forceSSL would have bounced
the gateway's plain-HTTP hop back to the gateway; and the oc vhost's explicit
listen on 100.84.190.30:80 was shadowing this vhost on the tailnet, serving the
opencode UI for Host: atproto.commoninternet.net.

Imports the notplants-atproto module: Docker daemon (this host had none), a
systemd unit running the project's docker-compose stack, and an nginx vhost
proxying to it on 127.0.0.1:8731 with ACME and websocket support.
Opens 80/443 publicly. Until now only 22 was open and everything else was
tailnet-only, so this is a real change in exposure — nginx is now reachable
from the internet. The existing oc.commoninternet.net vhost is untouched and
stays bound to the tailscale IP.
nix/atproto-likes.nix is a COPY; the canonical file lives in the project repo
at /srv/project-orchestrator/projects/notplants-atproto/nix/. Pure evaluation
forbids importing an absolute path outside the flake tree, so it has to be
duplicated here — and a new file must be git-added or nix silently ignores it.
ACME currently FAILS: *.commoninternet.net is a wildcard pointing at
143.244.213.108, so the HTTP-01 challenge is answered by that host (500).
nginx serves a self-signed placeholder and starts fine. Fix is an explicit
A record atproto.commoninternet.net -> 168.119.126.100, then
`systemctl start acme-atproto.commoninternet.net.service`.
Applied with nixos-rebuild switch; container healthy, TLS proxy and wss
verified end to end.
