Three headline answers.
1. The ceiling is REAL and on mp1 (/mnt/sys_drive), but its shape is a MISMATCH
rather than a single number. A1: docker's data-root is a SEPARATE 50G volume
(mp0) and every app volume resolves there, so app DBs are NOT on sys_drive -
build-golden.sh:68's "like the Docker-data" reading is correct. A2: the
recovery units ARE on sys_drive, which the golden ships at 20G. So a box
permits 50 GB of live app data while capping local backup at 20 GB, and
crossing that line is invisible until a backup fails.
A3 rules out the lab-default explanation: --sysdata-grow defaults to 0
(main.go:178) and is not computed from the drive. demo-hp's REAL guest 9201
runs a bare --config ExecStart and shows mp0 50G / mp1 20G; agent.json has no
sizing keys at all. A4, measured not read: restore extracts IN PLACE on the
docker volume - sys_drive avail was 799.2M before and after a restore run under
constraint - so the constrained mount is written only during backup.
2. Overflow behaves WELL. With sys_drive ballasted to 799 MB, backup refused
per-app ("No space left on device"), other apps continued, status reported
success=false, and the "last good dump preserved" claim VERIFIED byte-for-byte:
size and md5 unchanged, tar valid end-to-end, no .tmp residue. Restoring that
preserved unit under the same constraint returned correct data and claimed
success honestly. Explicitly NOT the R-156 family.
3. But it is SILENT - R-158, filed. Zero events reached the hub.
NotifyBackupFailed exists and the hub allowlists backup_failed, but the only
production caller is the off-box/NAS leg (main.go:659); the backup manager has
tier2/offbox/offbox-enlarge notify seams and none for the local recovery-unit
capture. This is R-97's shipped defect exactly one tier over, and the fifth
instance of "seam built but never wired" - a pattern the codebase names in its
own R-97 wiring test.
Sizing rule corrected: unit ~= volume-tar bytes + logical dump bytes, not a
constant 1.90x. Measured C1: file-only apps are 1.00x (homebox 2305->2305 MB, no
db-dumps dir at all), and the SAME DB app with an empty DB is also 1.00x. So a 20G
sys_drive holds ~19 GB file-only or ~10 GB DB-backed. That is the bound on D5's
Lane-1 independence.
C2: both representations are used for a reason stated in code (F17 - the dump is
authoritative and WINS over the tar; R-47 - replayed with only the DB service up).
The dump is single-database pg_dump --no-owner, so a fresh initdb plus the dump is
logically sufficient and the tar is a PHYSICAL FALLBACK. Dropping it would halve
DB-app units and also close the D5/R-127(b) password trap (restored PGDATA makes
postgres skip initdb and ignore POSTGRES_PASSWORD) - but only after ValidateDump
is promoted from a warning to a gate, since it currently WARNS on a dump whose
accounts table has no rows. In its present form the tar is load-bearing.
No production code, no template change. Teardown still owed and itemised.
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").

- 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.
