Carbon's entrypoint puts LD_PRELOAD=libdoorstop.so in front of the whole
startup string, and with Carbon's DOORSTOP_* environment that preloader
breaks the launcher shell's own command substitution: the sidecar's
--print-config output went straight to the console and the capture came
back empty. The first Carbon server built from the egg printed its config
JSON, token included, unframed, then "server id 'main', sidecar URL
http://192.168.0.12: (listening on )" and never the once-only banner.
`env -u LD_PRELOAD` on the sidecar alone was not enough: the shell doing
the capturing had the preload too.
The launcher now re-execs itself once without LD_PRELOAD, keeps it aside,
and gives it back to the game in run_game, the only process that needs it.
Reproduced and fixed under Carbon's real environment (environment.sh +
libdoorstop.so): the released launcher dumps the JSON; this one prints the
banner and "server id 'egg-carbon', sidecar URL http://192.168.0.12:21019",
and the game still gets LD_PRELOAD and DOORSTOP_ENABLED. The four
no-preload cases in the game image are unchanged.

`[game].server_id` was a cross-check that WARNED and kept the plugin's id.
The phase 18 walk showed what that costs: a second server's plugin,
parked in this listener's backlog by a plugin bug (Rust-Plugins, D154),
was accepted the moment the first server's plugin reloaded, and the
website showed server "alpha" with beta's hostname and wipe.
Now, with `server_id` set, the connection is closed on the first frame
that names another server, BEFORE that frame reaches the store or the
feed, and both ids are logged at ERROR. The command channel is installed
only once a frame has named this server, so no website command (a grant,
a world write) can reach a plugin about to be refused, and /health reports
the plugin connected only from then. Blank `server_id`: nothing checked,
as before.
The egg's launcher now hands the sidecar the plugin config's ServerId once
that file exists. The plugin reads RUSTLINK_SERVER_ID only at its first
config write (D150); without this, a variable edited after the first boot
would be refused instead of changing nothing, as INSTALL.md promises.
Walked: a plugin aimed at another server's sidecar is refused with an
ERROR naming both ids, and the site keeps the right server's identity.

Module-rust phase 18, step 4 of docs/modules/rust/PLAN.md §34.2.7.
The Windows service (D149, §34.2.5): src/windows.rs, ported from link's fix
for error 1053. The same exe tries the SCM handshake and falls through to a
console run on 1063; it reports Running only once the listener and store are
up, and logs to a daily file beside its config. One binary serves every
RunicGatewayRust-<id> instance, because the SCM ignores the dispatcher's name
for an own-process service.
An empty environment variable now counts as unset. A Pterodactyl egg exports
every variable it declares, so a blank RUSTLINK_WEB_TOKEN arrived as "" and
overrode the saved token, and a new one was generated and persisted on every
boot. That breaks D152, which this change makes true.
The egg (R20, R22, D151, D152, §34.2.6), in egg/:
- install.sh is egg 18's script with two changes. A wipe guard moves
rust-link/ to /tmp around `rm -rf ${REMOVE_FILES}`. The bridge block then
fetches a schema-2 Rust bundle (pinnable by RUNICGATEWAY_BUNDLE), checks
every asset's sha256 and the plugin's protocol before placing anything, and
places the plugin by FRAMEWORK. Vanilla installs nothing and does not fail.
- with-sidecar.sh is the launcher. It unsets blank variables, builds the web
bind from RUSTLINK_WEB_PORT, and runs --print-config so that a newly
generated token is printed once. It prints the URL and server id for the
admin page, then execs the game. It no longer uses `set -e`: nothing the
bridge gets wrong may keep the game from booting.
- The startup's launcher prefix is conditional, so a server with no bridge
boots exactly as egg 18 does.
- build.sh assembles egg-rust-runicgateway.json. PR Checks runs it.
The release (D145, §34.2.1) reuses servuo-plugins' engine. It publishes the
static musl Linux binary, the Windows exe, the launcher, the egg and
SHA256SUMS, and dispatches the installer's bundle.yml. PR Checks gains a
clippy run for the Windows target.
