PART A -- the poster. documentation/architecture/felhom-system-poster.html
(307 KB). Secret scan first: ZERO IPv4, zero PEM blocks, zero ssh keys, zero
Bearer. The one EAA... match is base64 inside an embedded "mime":"font/woff2"
blob, not a Facebook token. "token"/"secret"/"password" appear 11 times and
every one is a NAME ("6. ep0 read token", "the hub seal key"); the poster
itself says "Names only; no secret values". All five long base64 blobs are
declared assets: 1 image/png, 3 text/javascript, 1 font/woff2.
It renders with NO network: the source mentions cdn.jsdelivr.net and Google
Fonts, but the loaded requests are only the HTML plus blob:/data: URLs -- the
bundler inlined everything. Measured, not assumed, and it matters: this is a
disaster-recovery document, so needing the internet to draw would be a defect.
No console errors.
The operator's three Claude Design fixes are all present: (a) no "WG" badge,
WireGuard only for the tunnel, no badge on the ep0-copy tile; (b) the box ->
ep0 arrow reads "encrypted on the box, sent through WireGuard"; (c) "Known
gaps" holds two items and NOT the household-keys sentence, which is now a
neutral "By design" note under the ep0 household namespace.
ONE FACT ON IT WAS WRONG. The felhom.eu tile said "served from DooPlex through
Cloudflare". It is not: Cloudflare is DNS only and the traffic goes direct --
measured this morning for the privacy notice, which states exactly that. The
poster would have contradicted a published page. Fixed in place (a label):
"served from DooPlex, Cloudflare DNS only". The first wording overflowed the
fixed-size tile, so it was shortened to fit and the evidence lives in the
facts file instead -- checked by re-rendering, not by hoping.
PART B -- the facts and the rule. DESIGN-PROMPT-...md is renamed
felhom-system-poster.facts.md (one home per fact), with the three fixes folded
in as explicit instructions so a regeneration cannot undo them, plus a new
"Badges" section saying a "WG" chip must never come back.
New rule, section 6 "The system poster stays true", added IDENTICALLY to all
five copies of unprompted-work.md (the four repos and the workspace root on
DooPlex; verified identical by diff before and after) and to
PROMPT-TEMPLATE.md's end-of-session checklist as a FIFTH coupled artifact.
scripts/poster_facts_gate.py WARNS when the facts file has a newer commit than
the poster. It never fails a push, deliberately: a refresh needs Claude Design
and the operator, --no-verify is forbidden here, so a blocking gate would leave
deleting it as the only way out. It compares COMMIT times, not mtimes, because
a checkout rewrites mtimes and every fresh clone would shout.
RED-PROOF -- and it found a real bug in the gate. The first run warned
correctly but exited 1: a single non-ASCII character in its own warning raised
UnicodeEncodeError on this cp1250 console. A gate whose entire contract is
"never fails a push" was failing pushes. Fixed (ASCII output + an encode
guard), and the decoy now asserts BOTH the warning and exit 0. Three branches
proven: facts newer -> warns, rc 0; poster newer -> quiet, rc 0; poster
missing -> "could not tell", rc 2, not a false all-clear.
The decoy itself was seen to fail, twice, on Linux (the suite needs fcntl and
cannot run on Windows): breaking the warning gives STALE_WARNS=False, and
making it exit 1 gives RC_STALE=1. All 80 felhom.eu decoys behave.
PART C -- do box reports pass through Cloudflare? NO. Two channels. DNS from
PUBLIC resolvers (not DooPlex's own, which answers the LAN address):
hub.felhom.eu is a CNAME to dooplex.hopto.org -> 37.191.56.193, not a
Cloudflare address, and no cf-ray comes back. The manifest: an ordinary k3s
Ingress, Cloudflare named only in a DNS setup comment. THE CONTROL that makes
the negative mean something: iso.felhom.eu resolves to 172.67.x / 104.21.x,
real Cloudflare addresses -- so the method does detect proxying.
So nothing is added to the Cloudflare row: the hub path does not touch it.
06-offsite-connectivity.md section 1 claimed the public edge is a
Cloudflare-Tunnel and "DooPlex has no public IP" -- both untrue today. Kept
and marked STALE with the measurement rather than rewritten, because that
paragraph is the reason ep0 exists and the argument needs its premise visible.
total-loss-of-dooplex.md's "today a CNAME to dooplex.hopto.org" is confirmed
correct.
Register: 137 before, 137 after, 0 opened, 0 closed -- every finding here was
small and fixed in the session.
felhom.eu
Website, manifests, and infrastructure for Felhőm.eu — a managed home-server service for Hungarian households.
Overview
This repository contains:
- Website (
website/) — Static HTML pages served at felhom.eu - Kubernetes manifests (
manifests/) — All k3s deployments for the felhom.eu ecosystem - Assets (
website/assets/) — Logo, images, OG images
The website runs on a single-node k3s cluster alongside the rest of the Felhőm management infrastructure (Healthchecks, Umami analytics, contact mailer).
Branding
| Aspect | Value |
|---|---|
| Brand name | Felhőm.eu (with accent: ő) |
| Domain | felhom.eu (without accent — domain limitation) |
| Tagline | „Saját felhőd, saját szabályaid" |
| Controller product | Felhő Felügyelő (customer-facing name) |
| Controller code name | felhom-controller (backend/repo/container) |
| Language | Hungarian throughout all customer-facing content |
| Contact email | info@felhom.eu |
| Admin email | admin@felhom.eu |
Why "Felhőm"?
"Felhő" means "cloud" in Hungarian. The "m" suffix makes it possessive — "my cloud" (felhőm). The .eu domain is part of the brand identity and appears in the logo. The double meaning of "felhő" (tech cloud + weather cloud) is intentional and used in product naming (e.g., Felhő Felügyelő = "Cloud Supervisor/Inspector").

All pages use:
- Clean URLs — nginx serves
.htmlfiles without extension (/gyik→gyik.html) - Unified CSS — each page contains the full CSS (no external stylesheet, for simplicity)
- Responsive design — mobile hamburger menu, responsive grids
- UTF-8 with BOM — all HTML files are saved as UTF-8-BOM for Hungarian character support
- Umami analytics — privacy-friendly tracking script on every page

Website Deployment
The website uses a git-sync sidecar pattern:
git-synccontainer polls this repository (sparse checkout:/website/only)- Syncs to a shared
emptyDirvolume nginxcontainer serves from the synced content- Changes pushed to this repo are live within minutes (no manual deployment)
FileBrowser at files.felhom.eu provides a web UI for quick edits to website files (emergency fixes, asset uploads) without needing git. It writes to a Longhorn PVC that the website nginx also reads from.
Storage
All persistent data uses Longhorn distributed storage:
filebrowser-files(1Gi, ReadWriteMany) — website filesfilebrowser-db(100Mi) — FileBrowser SQLite databaseumami-db-data(2Gi) — Umami PostgreSQL datahealthchecks-data(1Gi) — Healthchecks SQLite data
DNS Configuration (Cloudflare)
Domain: felhom.eu — Cloudflare DNS (free plan), DNS only mode (no proxy/orange cloud).

File Encoding
All HTML files in website/ are UTF-8 with BOM (byte order mark). This ensures proper Hungarian character rendering (á, é, í, ó, ö, ő, ú, ü, ű) across all tools and platforms. The BOM is the 3-byte sequence EF BB BF at the start of each file.
When editing files, ensure your editor preserves UTF-8-BOM encoding. VS Code: check "UTF-8 with BOM" in the bottom status bar.
