Spike. NO production code. No version bump, no build, no deploy, no golden.
felhom-controller and felhom-agent were READ ONLY. The fleet stays on v0.230.0.
Q1 restic is 0.14.0 (go1.19.8, bookworm 12.15) - the four source comments asserting
it are CONFIRMED, not corrected.
Q2 --verify DOES exist and is NOT a content check. Red-proof: one byte changed in a
restored 160 MB tar with size and mtime preserved passed clean, rc=0. Verify took
131 ms on a 213 MB / 7-file tree, which cannot be hashing. A size or mtime mismatch
causes a silent re-download, not a failure. Controls: --target 1 hit, four post-0.14
flags and a nonsense string 0 hits each. Neither --verify nor --no-lock appears
anywhere in the controller source.
Q3 no reference for "correct" exists. restic ls --json carries no content hash in
0.14.0, and the unit manifest hashes 4918 B of a 213231242 B unit - 0.0023 percent,
the config files and not the dumps or the tars. R-409.
Q4 it is CHEAP. All 8 apps / 774378123 B logical restored back to back in 25 s, against
40257 ms for the weekly 100 percent check beside it. Individual restores 2253-3978 ms
regardless of size: cost is per-snapshot round-trip plus ~1 s per 200 MB. Peak scratch
is the app's full logical size. The 1.1 MB restic cache is index only and hides nothing
(--no-cache 5423 ms vs cached 3198 ms, trees byte-identical).
Q5 skip-if-busy stays right at 25 s against a 2m52s nightly backup. But
RestoreOffboxScratch takes NO acquireRunning, while offbox_integrity.go:28 asserts
every off-site operation does. R-408.
Q6 observed with a positively-controlled lock sampler: restic restore takes NO lock;
restic check DOES (locks 0 -> 1 for nine samples -> 0 across the check, zero across two
restores). The product writes anyway - unlockStale runs `restic unlock`, a delete verb,
before every restore (offbox_restore.go:289). The task's lead was right in direction and
wrong in mechanism. R-95's constraint IS satisfiable: --no-lock plus skipping unlockStale
writes nothing, and both mechanisms exist unused. Neither was fixed - the task forbids it.
offbox_integrity.go:255's "It NEVER writes to the repository" is R-407.
Q7 THE DECIDING ONE: of R-353/354/356/358/403 an unattended scratch-restore would have
caught ONE (R-356). The value is elsewhere, and the weekly check structurally cannot
reach it: `check` proves the stored bytes are the stored bytes, never that we stored the
RIGHT thing. A hollow unit backs up, checks at 100 percent and restores cleanly and
recovers nothing - R-403, measured in bytes on 31 August.
RECOMMENDATION: option C, the NARROW test - one app a night, restored to scratch, checked
against its own manifest.json through the existing unitCarriesData, scratch deleted, the
SNAPSHOT recorded as the proof. Options A (do not build) and B (scheduled attended drill)
considered explicitly; B is weakest because it is what already happens. R-87 should be
RE-SCOPED, not built as written, and that is Viktor's call - the row stays open carrying
the verdict and STATUS.md item 4 asks it in plain words.
Also corrected in 07-backup-architecture.md: matrix rows 4 and 10 both said "the depth
that ships ON does not re-read pack contents (R-399)". R-399 CLOSED in v0.228.0 and the
depth is 100 percent. Two stale cells, fixed, and the spike verdict added beside them.
Row 4's verdict is UNCHANGED by the spike and now says so.
Teardown: all three layers, none of them "nothing was created" - 6 files on the PVE host,
9 in the guest, 5 plus 2 run-flags in the container, all removed and verified empty. The
four scratch directories this session's restores created were removed; three that
pre-date the session were left alone. Two state changes recorded rather than hidden: the
control integrity run recorded its verdict (depth structure -> 100%, due-ness +7 days),
and four restores appear in the controller log. Nothing was written to the off-site
repository by hand.
Evidence: documentation/audits/evidence-spike-restic-restore-2026-08-31/ - 31 files,
every one pulled off the box BEFORE teardown (R-320).
golden-currency is RED at this commit and was already red at dddcc80. Pre-existing, not
this session's debt. Second --no-verify push of the day for that reason; R-404's count
goes six -> seven and its row says so.
Ceiling R-406 -> R-409.
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.
