Add generators.${BASE_DOMAIN}: a pinned fork of misode.github.io served
with its own mcmeta + vanilla-mcdoc mirror, so it works with zero internet
at the LAN party. Fork lives in ulicraft-generators (branch ulicraft),
pinned at upstream 2bfe5522.
The app is 100% client-side: every data fetch comes from the player's
browser, not from cochi. So offline capability is entirely about which
origins the bundle refers to, plus a mirror to serve them from. The vhost
sets Content-Security-Policy with connect-src 'self' as ENFORCEMENT: an
external origin that sneaks back in (or returns via an upstream merge)
then breaks loudly in prod, on an ordinary day, instead of silently at the
venue with no internet to debug it.
sync-generators-data.sh mirrors ~109M: the 1.21.1 summary/data/atlas tags,
assets-tiny (assets minus hundreds of MB of .ogg — hence no sounds
generator), vanilla-mcdoc symbols.json, and summary/versions/data.min.json,
which comes from a BRANCH head rather than a version tag and runs during
Spyglass init. It verifies a sentinel file per source instead of trusting a
clean clone exit, since a renamed upstream path would otherwise sync
"successfully" and only fail in the browser at the party.
The container serves the bundle and the mirror on one origin, so there is
no CORS, no second cert and no second DNS name.
DEPLOY ORDER MATTERS. GENERATORS_REPO must be set in cochi's .env BEFORE
pulling this: compose uses ${GENERATORS_REPO:?...}, and an unset required
variable makes docker compose fail to parse the file — taking down every
service including Minecraft, not just this one. Full runbook and the rest
of the prerequisites: plan/21-generators.md.
Verified offline in real Chromium with every non-origin request aborted:
zero off-origin attempts, zero same-origin failures, zero console errors,
generators rendering schemas and live JSON.
One shared login (htpasswd) for all players, writable. Config is rendered
from a template and mounted read-only, so git stays authoritative — the
admin console loads but cannot save, by design.
Filestash's OIDC/SAML middlewares are enterprise-only, so Keycloak SSO is
out; FILES_AUTH keeps htpasswd/passthrough switchable for later. Auth-off
(passthrough) is only valid once the host is off the public internet —
render-config.sh warns loudly when rendering it.
Three traps, all found by testing against the pinned image:
- the `local` backend is admin-gated: without LOCAL_BACKEND_SECRET in the
connection params every login fails with "backend error - Not Allowed"
- the htpasswd plugin only accepts $2a$ bcrypt, so a $2y$ hash from
`htpasswd -B` fails every login silently — use `openssl passwd -6`.
render-config.sh rejects the wrong format rather than shipping it
- APPLICATION_URL/ADMIN_PASSWORD env make filestash rewrite config.json at
boot, which fails on the :ro mount — both live in the rendered config

The landing page (apex origin) fetches launcher.json from the distribution
vhost cross-origin to render download buttons; add Access-Control-Allow-Origin
on /launcher/* so the browser doesn't block it. Public assets, no credentials.

Drop packwiz entirely. The server now loads a filtered mod subset from a
local ./server-mods volume instead of fetching a packwiz pack at boot.
New flow:
- tooling/classify-mods.py (tomllib only, no network) reads each jar's
META-INF/neoforge.mods.toml and seeds mods-sides.json with a side
(client|server|both; default both). Existing entries are preserved.
- mods-sides.json: committed, keyed by jar filename, hand-editable override
surface. Initial seed: 65 both, 11 client, 0 server (76 jars).
- tooling/sync-server-mods.sh mirrors the both/server jars from
$DISTRIBUTION_WEB_ROOT into ./server-mods/ (authoritative; prunes strays;
halts on a missing jar). Replaces render-pack.sh.
- compose: minecraft mounts ./server-mods:/mods:ro with REMOVE_OLD_MODS=TRUE
(itzg auto-syncs /mods -> /data/mods). Removed PACKWIZ_URL, the pack.
extra_host (auth. kept for authlib), and depends_on caddy (drasl kept).
Both classify-mods.py and sync-server-mods.sh resolve their source dir as:
CLI arg / MODS_DIST_DIR env / $DISTRIBUTION_WEB_ROOT (in that order).
Removed: tooling/render-pack.sh + add-custom-mod.sh (packwiz tooling),
pack/ (packwiz source), custom/ (76 jars now sourced from the distribution),
the pack. caddy vhost + its mounts/alias, and the packwiz .gitignore block.
Client distribution is UNCHANGED: HeliosLauncher still installs the full
modset from distribution.json. Docs (CLAUDE.md, plan/04/05/14, runtime)
updated; plan/04-packwiz.md stubbed as superseded by plan/04-mods.md.

Add a featured live ServerCard to the landing (replaces the static
ServerListPanel in hero + status sections): server favicon, color MOTD,
online/offline pill, players online/max with fill bar, and a player-head
row rendered by our own NMSR from Drasl skins. Progressive enhancement —
SSG skeleton degrades gracefully when JS or the API is unavailable.
Back it with a self-hosted pinger instead of the public api.mcstatus.io:
mcstatus.io's API service is closed-source (only the mcutil library is
open), so docker/mc-status wraps mcutil and re-emits its v2 JSON shape,
keeping the frontend unchanged. The service ignores the path address and
only pings MC_STATUS_TARGET (no SSRF relay), with a 30s TTL cache.
Exposed same-origin via caddy at the apex /api/mcstatus/* path (no new DNS
subdomain or LE cert change, no CORS). Uptime Kuma stays the uptime
history + alerting backend; see plan/15-mc-status.md.

Collapse the override-file matrix into a single docker-compose.yml holding the
whole stack: drasl, minecraft, mc-backup, caddy, nmsr, uptime-kuma. Bring-up is
now just `docker compose up -d --build`.
Removed features (dead-ends for this deployment):
- airgap / full asset mirror (mirror-airgap.sh, mirror-mods.sh, 20-mirror.caddy,
caddy local-CA export, /ca.crt)
- dnsmasq + avahi/mDNS + dns-records.sh + mdns-host-setup.sh + ENABLE_MDNS;
DNS is now handled outside this repo (HOST_LAN_IP dropped)
- Blessing Skin auth variant (compose + 00-core-blessingskin.caddy + BS_* env)
- host-nginx-static variant (docker-compose.nginx.yml, nginx/ulicraft.conf.tmpl)
- build-stack.sh and its run modes (online/airgap/core)
Production ingress is the only path now: host nginx terminates TLS (LE certs)
in front of caddy on a localhost-only port; caddy routes every vhost by Host
header. Launcher downloads move mirror/launcher -> launcher/.
Docs: README, deploy skill, and plan/ rewritten to match; obsolete plan docs
(dnsmasq, blessing-skin, assets-mirror, full-airgap-mirror, dns-and-run-modes)
deleted.

Add docker-compose.status.yml (louislam/uptime-kuma) layered on the caddy
ingress, joining mcnet so it probes the stack by internal service name and
the public vhosts end-to-end. Host port bound to 127.0.0.1:3001 only; public
access via nginx -> caddy.
- caddy/conf.d/50-status.caddy: status. -> uptime-kuma:3001
- nginx caddy-front template: status. TLS vhost + websocket upgrade headers
for Kuma's live UI; status. added to the HTTP->HTTPS redirect list
- status added to LE_SUBDOMAINS defaults (.env.example, issue-letsencrypt.sh)
- README: Status monitoring section + recommended monitor list (incl. native
Minecraft-protocol ping)

Serve a static site at distribution.${BASE_DOMAIN} whose web root lives in
another repo (DISTRIBUTION_WEB_ROOT, bind-mounted read-only into caddy):
- caddy/conf.d/30-distribution.caddy file_server vhost
- docker-compose.distribution.yml mount snippet + external web root
- issue-letsencrypt.sh / .env.example add distribution to LE_SUBDOMAINS
- ulicraft-caddy.conf.tmpl TLS-front block proxying to caddy

Rename the pack-serving vhost/alias from packwiz.${BASE_DOMAIN} to
pack.${BASE_DOMAIN} (caddy conf, caddy network alias, PACKWIZ_URL).
Inline the static-site caddy mounts (10-static.caddy, www, launcher,
CA cert) into the base compose; set MOTD to "Uli LAN party".

Override stack that swaps Drasl for Blessing Skin Server + MariaDB,
talking to Minecraft via the yggdrasil-api plugin (authlib endpoint
/api/yggdrasil, ONLINE_MODE=TRUE). Caddy auth.* repointed to
blessing-skin:80; Drasl left idle (compose merges depends_on).
Run: docker compose -f docker-compose.yml -f docker-compose.blessingskin.yml up -d

Air-gap mirror uses tls internal; guests must trust Caddy's local CA. Serve it
at http://<domain>/ca.crt from a world-readable mount (the live pki dir is
root-only 0600). build-stack --up mirror|full exports the CA after bring-up;
landing page links it. Pre-creates the mount target to avoid a dir bind.

Base Caddyfile now imports conf.d/*.caddy. Snippets are mounted selectively
so the stack runs with or without the static site / air-gap mirror:
00-core auth + packwiz (always)
10-static apex landing + launcher downloads
20-mirror air-gap upstream hosts (tls internal)
