oierandClaude Opus 4.8 16523e4f62 feat(files): move filestash to upload., serve files. as read-only static browse
Filestash cannot be served under a subpath (its SPA hardcodes /api, /assets,
/login at root), so it moves to its own subdomain upload.${BASE_DOMAIN}. The
apex-level ask was a static, no-auth file browser at files.${BASE_DOMAIN}: caddy
now file_server browse's the same ${FILES_DATA_DIR} share read-only there.

- filestash general.host -> upload.; nginx upload. vhost keeps the 2g body +
  upload streaming + /admin throttle; new files. vhost is a plain static proxy.
- caddy: 60-files.caddy split into 60-upload.caddy (filestash) + 62-files.caddy
  (file_server browse of /srv/files); caddy mounts FILES_DATA_DIR :ro.
- LE_SUBDOMAINS += upload (both upload. and files. are vhosts needing certs).

Security: files. is unconditionally public read (no auth), independent of
FILES_AUTH. The htpasswd login only gates writes via upload. Documented.

# 19 — HTTP route reference (nmsr, landing, auth)
> Quick map of the public + internal HTTP routes. caddy (`caddy/conf.d/*.caddy`)
> is the internal router; the host nginx terminates TLS and forwards each vhost
> to it by Host header. All `${BASE_DOMAIN}` = `ulicraft.net` in prod.
## Vhost → service (caddy)
| Vhost | caddy file | Upstream |
|-------|-----------|----------|
| `${BASE_DOMAIN}` (apex) | `10-static.caddy` | static `/srv/www` + `/srv/launcher` + mc-status |
| `auth.${BASE_DOMAIN}` | `00-core.caddy` | `drasl:25585` |
| `avatar.${BASE_DOMAIN}` | `40-avatar.caddy` | `nmsr:8080` |
| `status.${BASE_DOMAIN}` | `50-status.caddy` | `uptime-kuma:3001` |
| `upload.${BASE_DOMAIN}` | `60-upload.caddy` | `filestash:8334` |
| `files.${BASE_DOMAIN}` | `62-files.caddy` | static `/srv/files` (read-only, no-auth browse of the share) |
| `distribution.${BASE_DOMAIN}` | `30-distribution.caddy` | static `/srv/distribution` (other repo) |
| `generators.${BASE_DOMAIN}` | `70-generators.caddy` | `generators:80` (offline misode fork + data mirror) |

## NMSR — `avatar.${BASE_DOMAIN}` (skin/avatar renderer)
`reverse_proxy nmsr:8080`. Stateless renderer; pulls profiles+skins from Drasl
over mcnet (no public round-trip).
- `GET /{mode}/{uuid}?size=N` — render an avatar PNG.
- `mode` = any NMSR render mode (`headiso` is the configured default via
`AVATAR_MODE`; others incl. `head`, `face`, `fullbody`, `fullbodyiso`).
- `uuid` = Drasl player UUID; `size` = px.
- Landing usage: `${avatarUrl}/${avatarMode}/<uuid>?size=64|96`.
- **No per-request refresh.** A `?skin=<url>` override is **ignored** by this
build (tested). Skin changes propagate via the resolve cache only.
- Caching (`nmsr/config.toml`): `resolve_cache_duration = 60s` (uuid→profile,
bounds stale-avatar window), `texture_cache_duration = 48h` (safe — Drasl skin
URLs are content-hashed, new skin = new URL). Instant global flush = restart
nmsr. See `plan/03-drasl.md` for the Drasl-backed mojank wiring.
---
## Landing — `${BASE_DOMAIN}` (apex)
`10-static.caddy`. Three handlers:
- `handle_path /launcher/*` → `/srv/launcher` (file browse) — launcher downloads.
- `handle /api/mcstatus/*` → `uri strip_prefix /api/mcstatus` → `mc-status:8080`:
- `/api/mcstatus/v2/status/java/<addr>` → internal `/v2/status/java/` — live
server status JSON (mcstatus.io-compatible, `CORS: *`, `<addr>` ignored — it
only pings `MC_STATUS_TARGET`). Landing `statusApi`.
- `/api/mcstatus/players` → internal `/players` — registered-players roster,
sanitized `[{uuid,name}]`, ~60s cache (mc-status admin-logs-in to Drasl
`GET /players`). Landing `rosterApi`.
- `/healthz` — mc-status liveness (internal).
- `handle {}` → `/srv/www` static (Astro output). Pages: `/`, `/es`, `/eu`
(index), `/{lang}/register`, `/{lang}/account`, `/{lang}/fjord`.
Browser → Drasl **directly** (CORS-scoped to apex via Drasl `CORSAllowOrigins`),
base `https://auth.${BASE_DOMAIN}/drasl/api/v2` (`site.draslApiUrl`):
- `register.astro`: `POST /users` (register), `POST /login`, `PATCH /players/{uuid}` (set initial skin).
- `account.astro`: `POST /login`, `PATCH /players/{uuid}` with `{skinBase64,skinModel}` (upload) or `{deleteSkin:true}` (reset).
---
## Files — `files.${BASE_DOMAIN}` (Filestash player share)
`reverse_proxy filestash:8334`. Screenshots / schematics / maps. **One shared
login** for every player (`FILES_AUTH=htpasswd`), writable. Full design:
`plan/20-files.md`.
- `/` — SPA. The login form renders **only** at
`GET /api/session/auth/?action=redirect&label=files`. Without `action=redirect`
the request falls through to the credential check, fails with empty creds and
303s back to `?action=redirect` — so a bare `/api/session/auth/?label=files`
returning a 303 is **normal, not a bug**. `POST` with `user`/`password`
authenticates.
- `GET /api/config` → `result.origin` must be `https://files.${BASE_DOMAIN}`.
It's built as `(force_ssl ? https:// : http://) + general.host`, so a scheme in
`general.host` yields `http://https://…` and silently breaks every browser
while the server keeps answering 200. Check this after any config change.
- `/api/*` — JSON API. Requires the header `X-Requested-With: XmlHttpRequest`
(the SPA sends it); without it Filestash's intrusion detection 403s the
request. Relevant when curling it by hand.
- `/admin` — admin console, own bcrypt password (`auth.admin`). Deliberately
public; nginx throttles it (`limit_req`, 6r/m). It **cannot save** — the
config is a read-only mount.
- **`?label=files` matters.** The attribute mapping is keyed by the connection
label; auth without it yields `backend error - Not Allowed`.
Filestash blocks any request whose `Host` doesn't match its `general.host`
(`https://files.${BASE_DOMAIN}`) — nginx forwards the original Host and caddy
passes it through, so don't rewrite it anywhere in the chain.
---
## Auth / Drasl — `auth.${BASE_DOMAIN}`
`reverse_proxy drasl:25585`. One service exposes three surfaces:
- **Web UI:** `/` (login / register / profile pages), `/web/texture/skin/<sha256>.png`, `/web/texture/cape/<sha256>.png`.
- **Yggdrasil / authlib-injector:** `/authlib-injector` (API root — server JVM
agent + clients point here), `/session/minecraft/...`, mojang-compat
`/users/profiles/minecraft/{name}` and `/session/minecraft/profile/{uuid}`
(also what NMSR calls internally).
- **Drasl REST API v2** (`/drasl/api/v2`):
- `POST /login` `{username,password}` → `{apiToken}`
- `POST /users` `{username,password[,inviteCode]}` — register (invite-gated when `RequireInvite=true`; admins from `DefaultAdmins` are promoted at startup, see `plan/03-drasl.md`)
- `GET /players` — **admin only**, full roster
- `PATCH /players/{uuid}` — skin CRUD (own player, or admin)
- `POST /invites` — admin, mint invite codes
---
## Internal (service → service, over mcnet)
- `minecraft` → `-javaagent authlib-injector=http://auth.${BASE_DOMAIN}/authlib-injector` (caddy mcnet alias → drasl).
- `nmsr` → `http://auth.${BASE_DOMAIN}` (mojang-compat session/textures/api).
- `mc-status` → `http://drasl:25585/drasl/api/v2` (`DRASL_API_URL`) for the roster; pings `MC_STATUS_TARGET` for live status.
- `mc-backup` → RCON `minecraft:25575`.
