- Use [[ ]] instead of [ ] for conditional tests in the bash packaging scripts (S7688). Every
converted test compares quoted values to literals, so no pattern-matching change.
- Name positional parameters with locals inside functions (S7679).
- End the env.sh helpers with an explicit return that keeps their exit status (S7682).
- Give case statements a default branch (S131).
- Send the check-app-specific.sh error to stderr (S7677).
packaging/freebsd/package.sh is left alone while #1158 rewrites it.
packaging/server/install.sh sets up Debian/Ubuntu behind Caddy: binary from
its release archive, the source tree it sits in, the latest release or a
clone (temporary swap under 2 GB of memory), user, dirs and config only when
missing, systemd unit, Caddy site, nightly backup timer, ufw for 22/80/443;
safe to re-run for upgrades. docs/server.md gains Running a public server
(limits, expiry, moderation, operator responsibility, no end-to-end
encryption, threat model) and an install.sh walk-through; protocol, MCP,
CLI and parity docs updated.
The desktop app joins wss:// sessions (rustls with webpki roots, certificates always checked, clear errors; FIGCRAFT_CA_FILE for private authorities), with one TLS session shared by the reader and writer threads. figcraft-server stops gracefully on SIGTERM/SIGINT/SIGHUP/Ctrl+C, ships in Linux x86_64/aarch64 release archives, and docs/server.md gains a Deploy on a Linux server guide with a hardened systemd unit, Caddyfile, nginx config and Dockerfile in packaging/server.
