docs(files): record the general.host trap + that a green monitor proves nothing

Propagate the bare-hostname fix (10b86ae) to the docs that still said "three traps", and write down the meta-lesson it exposed. The bug was invisible to every check we had: Filestash strips the scheme before its own Host check, so `curl /` returned 200, the API answered, wrong passwords were rejected, and the brand-new Uptime Kuma HTTP monitor stayed green — while the SPA computed `http://https://files...` and no browser could use the site. An HTTP monitor asserts "server returned 200", which is a much weaker claim than "the app works". - CLAUDE.md / README: four traps now, host-scheme first; add the post-change check (`/api/config` → origin must be the real https URL). - 19-routes: login form only renders at ?action=redirect (a bare 303 is normal, not a bug); assert origin after config changes. - 10-uptime-kuma: an HTTP monitor cannot see an SPA break — use a Keyword monitor if you want teeth, and don't read green as "users can log in".

+Full list in `plan/20-files.md`; the ones that cost real time:
+- **`general.host` is a BARE HOSTNAME** (`files.${BASE_DOMAIN}`, no scheme) +
+  `force_ssl: true`. The SPA builds its origin as `scheme + host`, so a URL there
+  yields `http://https://files...` and every client-side redirect dies. The
+  server strips the scheme before its own Host check, so **curl and the uptime
+  monitor stay green while every browser is broken**. Cost a debugging round on
+  2026-07-14.
+- The `local` backend is **admin-gated**: without `LOCAL_BACKEND_SECRET` in the
+  connection params, every login fails with `backend error - Not Allowed` (looks
+  like bad credentials, isn't).
+- `FILES_PASSWORD_HASH` must be **`$6$`** (`openssl passwd -6`). A `$2y$` bcrypt
+  from `htpasswd -B` fails every login silently — the plugin only matches `$2a$`.
+- `config.json` is rendered + mounted `:ro` (the admin console can't save, on
+  purpose). Single-file bind mount ⇒ **`--force-recreate` after re-rendering**,
+  never `restart`.
+
+**Verifying an SPA:** a 200 on `/` proves the server is up, not that the app
+works. After any filestash config change, check the browser-facing values
+(`curl /api/config` → `origin`) and re-read `docker compose logs filestash` —

+## Player file share (Filestash)
+
+`files.${BASE_DOMAIN}` is a web file share for player media — screenshots,
+schematics, maps, guides. **One shared username/password for everybody**
+(`FILES_USER` / `FILES_PASSWORD_HASH`), read **and** write. It is *not* a backup
+browser and *not* a mod mirror: world snapshots contain every player's inventory
+and coordinates, and the modset already ships via `distribution.`.
+
+Full design, deploy steps and gotchas: **`plan/20-files.md`**. The short version:
+
+- Config is `filestash/config.json`, **rendered from a template and mounted
+  `:ro`** — git is the source of truth. The admin console at `/admin` loads but
+  **cannot save**; that's deliberate. Change config by editing the `.tmpl`,
+  re-rendering, and **recreating** the container (`up -d --force-recreate
+  filestash` — a single-file bind mount pins the inode, so `restart` reads the
+  stale file).
+- Files live in `${FILES_DATA_DIR}` on the host, outside the repo. **Not backed
+  up** by mc-backup — treat the share as disposable.
+- `FILES_MOUNT_MODE=ro|rw` is the literal mount flag: `ro` makes the share
+  read-only at the *kernel*, whatever the UI thinks.
+- `FILES_AUTH=htpasswd|passthrough` — `passthrough` means **no login at all**.
+  Only valid once the host is off the public internet: an unauthenticated
+  *writable* share on a public domain is an open upload relay.
+
+Four traps that cost real time (all enforced or documented in the tooling):
+
+- **`general.host` is a bare hostname**, no scheme (`files.${BASE_DOMAIN}`), with
+  `force_ssl: true`. The SPA builds its redirect origin as `scheme + host`, so a
+  URL there produces `http://https://files...` and every client-side redirect
+  breaks. The server strips the scheme before its *own* Host check, so `curl`
+  and the uptime monitor stay **green while every browser is broken**.
+- **`FILES_PASSWORD_HASH` must be `$6$`** (`openssl passwd -6`). The htpasswd
+  plugin's bcrypt branch only matches `$2a$`, so a `$2y$` hash from
+  `htpasswd -B` fails *every* login, silently. `render-config.sh` rejects it.
+- **The `local` storage backend is admin-gated** — without `FILES_LOCAL_SECRET`
+  reaching it through the connection params, every login dies with
+  `backend error - Not Allowed`, which looks like bad credentials and isn't.
+- **Don't set `APPLICATION_URL`/`ADMIN_PASSWORD` env** — either makes Filestash
+  rewrite `config.json` at boot, which fails against the `:ro` mount.
+
+> Verifying this service: a 200 on `/` only proves the server is up. Check the
+> browser-facing origin — `curl -s -H 'X-Requested-With: XmlHttpRequest`
+> `https://files.${BASE_DOMAIN}/api/config | jq -r .result.origin` must print
+> `https://files.${BASE_DOMAIN}` — and re-read `docker compose logs filestash`.

 ```
 authlib URL uses the `auth` subdomain; resolves internally via the caddy alias.
 (Server still needs the agent even though Fjord clients have it built in.)

+**`ONLINE_MODE` MUST be true.** authlib-injector works by redirecting the
+server's normal online-auth handshake from Mojang to Drasl. With
+`ONLINE_MODE=FALSE` the server skips that handshake entirely → players get
+offline-hash UUIDs, no session validation, and **no skins** (the server never
+fetches textures from Drasl). The thing that must stay *off* for 1.21+ is the
+**secure profile** (`ENFORCE_SECURE_PROFILE=FALSE` + Drasl `SignPublicKeys=false`),
+not online-mode. Symptom of getting this wrong: everyone can join but everyone is
+Steve, and `usercache.json` shows offline-hash UUIDs.
+
 Memory: `INIT_MEMORY 4G`, `MAX_MEMORY 10G`, `USE_AIKAR_FLAGS TRUE`.
 RCON enabled for mc-backup.

+## Server operators (OP)
+
+**Do NOT use the itzg `OPS` env var.** It resolves usernames to UUIDs via a
+Mojang lookup, but this server is `ONLINE_MODE=TRUE` validated against Drasl —
+Drasl assigns its own UUIDs (not Mojang, not the offline-hash). A Mojang-resolved UUID
+would not match the player's real session UUID, so the op entry would be inert
+(and could clobber a correct `ops.json` on reboot).
+
+**Op via RCON instead.** The player must have connected at least once so their
+real Drasl UUID is cached in `/data/usercache.json`; then `op <name>` writes that
+cached UUID to `ops.json`. On the host:
+
+```
+ssh cochi
+docker exec minecraft rcon-cli list                 # confirm cache / who's on
+docker exec minecraft sh -c 'cat /data/usercache.json'   # verify name→UUID cached
+docker exec minecraft rcon-cli op <name>
+docker exec minecraft sh -c 'cat /data/ops.json'    # verify level 4 + right UUID
+```
+
+`ops.json` lives in the `mc_data` volume → persists across restarts; no reboot
+needed (takes effect live). Current op: `oier`
+(`7fbc9adb-bcf4-3913-9a99-46d46acd1009`), level 4, set 2026-06-21.
+
+## Simple Voice Chat — `voice_host` (NOT repo-tracked)
+
+Voice chat is UDP `24454/udp`, published in compose. The mod auto-generates
+`/data/config/voicechat/voicechat-server.properties` in the `mc_data` volume.
+
+**Gotcha — `voice_host` must be set or remote clients get a red/crossed icon.**
+Behind any NAT/Docker the server announces an address for clients' UDP
+connection; if `voice_host=` is empty it auto-detects the internal Docker IP →
+unreachable → the secret (TCP) is sent but the UDP handshake never completes
+("Sent secret" with no following "successfully connected to voice chat").
+
+Set on prod:
+
+```
+docker exec minecraft sed -i 's/^voice_host=.*/voice_host=ulicraft.net/' \
+  /data/config/voicechat/voicechat-server.properties
+docker restart minecraft   # mod reads props only at startup
+```
+
+**⚠️ This value lives in the `mc_data` volume, NOT auto-managed from this repo.**
+It survives restarts and `compose down/up`, but a **world wipe / fresh `mc_data`**
+regenerates the file with `voice_host=` empty → voice silently breaks again.
+
+A known-good prod snapshot is committed at
+`server-configs/voicechat-server.properties` (reference copy, `voice_host=ulicraft.net`).
+After a world reset, either re-run the `sed` + `docker restart` above, or restore
+the snapshot:
+
+```
+docker cp server-configs/voicechat-server.properties \
+  minecraft:/data/config/voicechat/voicechat-server.properties
+docker restart minecraft
+```
+
+(Snapshot is not auto-mounted — to make it durable, add a bind mount of
+`server-configs/voicechat-server.properties` into `/data/config/voicechat/` in
+compose.)
+
+Verify after a client joins:
+`docker logs minecraft 2>&1 | grep -i "connected to voice"` → expect
+`Player <name> ... successfully connected to voice chat`.
+
+Note: a red voice icon can ALSO be client-side — a VPN/zero-trust client
+(Cloudflare One/WARP, FortiClient) on the player's machine silently drops the
+voice UDP. Rule out VPNs before touching the server.

+
+## Decisions (settled — don't relitigate)
+
+**Auth is htpasswd with one shared credential, not SSO.** Filestash's OIDC and
+SAML middlewares are **enterprise-only**; the community build compiles in
+`htpasswd`, `ldap`, `passthrough`, `wordpress`, `local` only (verified in
+`server/plugin/index.go`). Keycloak was considered and dropped — it would need an
+oauth2-proxy sidecar in front + `passthrough`. That path stays open but is not
+built.
+
+**One instance, everything behind the password.** No anonymous read tier.
+Filestash's auth middleware is **global to the instance**, so "anonymous read +
+authenticated write" is impossible in one container (that's the enterprise
+RBAC). A two-instance split was designed and rejected as not worth it.
+
+**`FILES_AUTH=none` is gated on the host being internal-only.** The off-switch
+exists for when this server moves behind a LAN/VPN. **Do not set it while
+`files.` is internet-reachable** — auth-off on a *writable* public share is an
+open upload relay: someone parks malware or a phishing kit on your domain, under
+your LE cert, and the abuse mail, the bandwidth, and a possible domain
+blocklisting (which would take `auth.` and the apex down with it, breaking logins
+and the launcher for every player) all land on you. `render-config.sh` prints a
+loud warning when it renders this mode.
+
+**Shared credential ⇒ no audit trail, no per-person revocation.** You will never
+know who deleted a folder; rotating means re-telling everyone. Fine for a
+friends' media share — but nothing here is backed up, so treat the share as
+disposable and keep anything you'd miss elsewhere.

+## What goes in it
+
+| Content | Verdict |
+|---|---|
+| Screenshots, schematics, maps, guides | ✅ the point |
+| World downloads / `./backups/*.tgz` | ❌ contains `playerdata/`, `stats/`, the full map — every player's inventory and coords, handed to anyone with the shared password |
+| Mods / jars | ❌ redistribution; `distribution.${BASE_DOMAIN}` already serves the modset to launchers |
+
+## `.env`
+
+See `.env.example` for the annotated block. Summary:
+
+| Var | What |
+|---|---|
+| `FILES_DATA_DIR` | host path of the share, outside the repo |
+| `FILES_MOUNT_MODE` | literal mount flag, `rw` \| `ro` |
+| `FILES_AUTH` | `htpasswd` \| `passthrough` \| `none` |
+| `FILES_USER` | shared login name |
+| `FILES_PASSWORD_HASH` | **`$6$`**, from `openssl passwd -6 '<pw>'` |
+| `FILES_ADMIN_PASSWORD_HASH` | bcrypt, from `docker run --rm caddy:alpine caddy hash-password --plaintext '<pw>'` |
+| `FILES_SECRET_KEY` | `openssl rand -hex 16`, must be non-empty |
+| `FILES_LOCAL_SECRET` | `openssl rand -hex 24`, unlocks the local backend |
+| `LE_SUBDOMAINS` | must include `files` |
+
+`filestash/config.json` is **rendered and gitignored** — it holds every hash and
+both secrets. Only the `.tmpl` is tracked.

+
+Then add an Uptime Kuma HTTP monitor for `https://files.${BASE_DOMAIN}` (expect
+`200` — the login page is a 200) and put it on the status page with the others.
+
+## Gotchas (all of these were hit for real)
+
+### The `local` backend is admin-gated — this is the one that wastes an evening
+`plg_backend_local.Init()` **refuses to start** unless the connection params
+carry `$LOCAL_BACKEND_SECRET` or the bcrypt admin password. Miss it and every
+login dies at `backend error - Not Allowed`, which reads like a credentials
+problem and isn't. `config.json`'s `attribute_mapping` injects the secret
+server-side (Filestash calls this the "facade pattern"), so players never see it.
+`FILES_LOCAL_SECRET` must be **identical** in the compose env and the rendered
+config — `render-config.sh` renders both from the same var.
+
+### `$2y$` bcrypt silently fails every login
+The htpasswd plugin's bcrypt branch matches on the literal prefix **`$2a$`**.
+`htpasswd -B` emits `$2y$`, which falls through to `return false` — so every
+login fails with correct credentials and no useful log line. Use
+**`openssl passwd -6`** (`$6$`, sha512) for `FILES_PASSWORD_HASH`.
+`render-config.sh` hard-fails on a `$2y$`/`$2b$` hash rather than shipping a
+config nobody can log into. (The *admin* password is checked by Go's bcrypt
+directly, which does accept `$2y$` — but `caddy hash-password` gives `$2a$`
+anyway, so just use that for both.)
+
+### `general.host` is a BARE HOSTNAME — a scheme breaks the browser only
+`"host": "files.ulicraft.net"`, **not** `"https://files.ulicraft.net"`, plus
+`"force_ssl": true`. The SPA computes its redirect origin as
+`(force_ssl ? "https://" : "http://") + host`, so a scheme in `host` yields
+**`http://https://files.ulicraft.net`** and every client-side redirect dies —
+the page loads, then silently fails to route anywhere.
+
+The vicious part: the server-side Host check (`SecureOrigin`) **strips** the
+scheme before comparing, so the server is perfectly happy. `curl /` returns 200,
+the API answers, and the Uptime Kuma monitor stays green — **only real browsers
+break**. Symptom in the log is a `POST /report?...msg=Redirecting to
+http://https://...` line. Hit this on 2026-07-14; fixed in `config.json.tmpl`.
+
+`force_ssl` only sets an HSTS header — it does **not** redirect, so it can't loop
+behind the nginx→caddy (plain http) hop. It must be `true` or the SPA builds
+`http://` origins on an https page.
+
+### `general.host` must also match the incoming `Host` header
+Filestash blocks every non-`/admin/` request whose `Host` differs from
+`general.host`, with *"only traffic from X is allowed"* — a 403 that looks like
+an auth failure. nginx forwards the original Host and caddy passes it through —
+don't rewrite it anywhere.
+
+### The login form only renders at `?action=redirect`
+`GET /api/session/auth/` renders the htpasswd form **only** when
+`action=redirect` is present; any other request falls through to the credential
+check, fails with empty creds, and 303s back to `?action=redirect`. So the real
+form URL is `/api/session/auth/?action=redirect&label=files`. A bare
+`/api/session/auth/?label=files` returning a 303 is **normal**, not a bug.
+
+### `config.json` is a single-file bind mount → stale inode
+Same shape as the caddy `conf.d` gotcha. The mount pins the **inode**, so
+re-rendering (or a `git pull`) writes a *new* file while the container keeps
+reading the *old* one.
+
+**After re-rendering: `docker compose up -d --force-recreate filestash`.**
+`restart` is not enough. Rotating the shared password needs a recreate too.
+
+### Don't set `APPLICATION_URL` or `ADMIN_PASSWORD` env
+Either one makes Filestash **rewrite `config.json` at boot**, which fails against
+the `:ro` mount. Both live in the rendered config instead (`general.host` /
+`auth.admin`). `general.secret_key` must likewise be non-empty, or Filestash
+generates one and tries to save that. With all three set in the file, Filestash
+never attempts a boot write and the `:ro` mount is clean — you get one harmless
+`cannot chmod config file` WARN in the log, and nothing else.
+
+### The admin console cannot save
+`/admin` loads and its login works, but `config.json` is `:ro`, so every save
+silently fails. That's the deliberate trade for keeping git authoritative
+(drasl/nmsr never write their configs; Filestash does, which is exactly why it
+needs pinning). To change config: edit the `.tmpl`, re-render, recreate. To
+re-derive the schema after an upstream upgrade: run the image locally against a
+*writable* state volume, click it into shape, `docker cp` the result out.
+
+### The API needs `X-Requested-With: XmlHttpRequest`
+The SPA sends it; anything else (curl, a naive monitor) trips intrusion
+detection and gets a 403 that looks like an auth bug. Only matters when probing
+by hand — the Kuma monitor hits `/`, which is fine.
+
+### Disk is the shared failure domain
+`FILES_DATA_DIR` grows without a quota, driven by whoever has the password. A
+full disk on `cochi` does not just break `files.` — it takes **Minecraft, Drasl,
+and mc-backup** down with it. Eyeballing is the accepted plan. Revisit (quota,
+separate partition, or a Kuma disk monitor) if the share sees real use.
+
+### Pinned digest, not `latest`
+`machines/filestash` publishes essentially only `latest`. Unpinned, any
+`docker compose pull` silently ships a new upstream build of an internet-facing,
+writable file manager. Pin the digest; upgrade deliberately — same discipline as
+`NEOFORGE_VERSION`.
+
+## Deferred
+
+- **Keycloak SSO** — needs oauth2-proxy + `FILES_AUTH=passthrough`. Not built.
+- **Anonymous access** (`FILES_AUTH=none`) — only once the host is internal-only.
+- **Landing page link** — deliberately none on day one; `plan/18-landing-rework.md`
+  is mid-rework, so revisit with WS5 (footer) rather than merging into a moving
+  design.
+- **Per-user accounts / roles** — htpasswd RBAC is enterprise-only.
+- **Backups / quota** — none.

Oier Bravo Urtasun	08fe8c9c53	docs(files): record the general.host trap + that a green monitor proves nothing Propagate the bare-hostname fix (`10b86ae`) to the docs that still said "three traps", and write down the meta-lesson it exposed. The bug was invisible to every check we had: Filestash strips the scheme before its own Host check, so `curl /` returned 200, the API answered, wrong passwords were rejected, and the brand-new Uptime Kuma HTTP monitor stayed green — while the SPA computed `http://https://files...` and no browser could use the site. An HTTP monitor asserts "server returned 200", which is a much weaker claim than "the app works". - CLAUDE.md / README: four traps now, host-scheme first; add the post-change check (`/api/config` → origin must be the real https URL). - 19-routes: login form only renders at ?action=redirect (a bare 303 is normal, not a bug); assert origin after config changes. - 10-uptime-kuma: an HTTP monitor cannot see an SPA break — use a Keyword monitor if you want teeth, and don't read green as "users can log in".

Oier Bravo Urtasun	10b86ae23e	fix(files): general.host must be a bare hostname, not a URL The SPA computes its redirect origin as (force_ssl ? "https://" : "http://") + general.host. With host set to "https://files.${BASE_DOMAIN}" that produced "http://https://files.ulicraft.net", so every client-side redirect broke and the page never routed anywhere. Server-side this was invisible: SecureOrigin strips the scheme before the Host check, so `curl /` returned 200, the API answered, and the uptime monitor stayed green — only real browsers failed. The tell is a `POST /report?...msg=Redirecting to http://https://...` line in the log. Set host to the bare hostname and force_ssl=true (which the origin needs to build https://, and which only emits an HSTS header — it does not redirect, so it can't loop behind the plain-http nginx→caddy hop). Verified: origin is now "https://files.ulicraft.net"; login + ls still work. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-07-14 18:27:42 +02:00
Oier Bravo Urtasun	cd79b0e540	docs(files): document filestash across plan/README/deploy skill Fold files./filestash into the docs that carry the service list, the vhost map and the deploy procedure — README stack table, 00-overview, 02-caddy, 12-build-order, 14-deploy, and the deploy skill. Two real gaps the filestash deploy exposed, now guardrails in the skill: - update-all.sh never touches host nginx, so a NEW SUBDOMAIN silently 404s after deploy. It needs issue-letsencrypt.sh + render-nginx.sh --install. - a new service with ${FOO:?} guards fails the WHOLE compose file, so a missing .env var means `up` starts nothing — and --hard has already run `down`. Check the host's .env BEFORE tearing the stack down. Also: filestash/config.json is a single-file bind mount re-rendered every run, so a rolling update-all leaves it on a stale inode (same trap as the caddy conf) — force-recreate after any FILES_* change. Correct the cochi divergence section: `git diff HEAD` on the host is now empty (verified this deploy — the ff-pull succeeded). The documented docker-compose.yml/package.json divergence was converged; only untracked dnsmasq/, caddy-root-ca.crt and a stale pack/ remain. The stash-pull-pop procedure it prescribed is no longer needed. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-07-14 18:23:18 +02:00
Oier Bravo Urtasun	25df9f9398	feat(files): add Filestash player file share at files.${BASE_DOMAIN} 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 Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-07-14 18:08:46 +02:00
Oier Bravo Urtasun	1958a96acf	chore(mods): classify 11 new distribution mods Distribution added 11 jars. classify-mods.py seeds all as `both` (none declare CLIENT in neoforge.mods.toml). Hand-flip the two pure-client cosmetic ones so sync-server-mods.sh drops them: - ExtremeSoundMuffler: client-side sound muffling UI - ToastControl: client-side toast popup suppression Rest stay `both` — Placebo/moonlight/caelus are libs, and amendments/etched/fishingoverhaul/immersive_paintings/ createornithopterglider/emotecraft add server-side content or sync. Also map iris as `client`. It is referenced by distribution.json but absent from the local (gitignored) dist jar dir, so classify-mods.py never sees it; mapping it keeps mods-sides.json aligned with the manifest.
