v0.100.x removed the serialisation: 26.2s -> ~9.85s mean. What remained was one Gitea package SEARCH per dropdown at 0.20-3.8s depending on load, which concurrency cannot help. Memoised for 60s IN MEMORY. The TTL was ruled by the operator against the workflow that cares: a bake-and-vouch session publishes an artifact and comes straight here to select it, so a minute is short enough not to be noticed and long enough that every reload in that session is instant. NOT persisted. Gitea IS the store for both the version list and the sha; a copy in hub_settings would be a second source of truth that can drift from the registry it describes, and the operator reads the sha here to confirm what they are about to vouch. An in-memory cache dies with the process and can never be mistaken for a record. A failed resolve is NOT cached — a blip must not pin an empty dropdown for a minute. But an empty list from a package that genuinely has no versions IS cached, because 'we found nothing' and 'we could not look' are different answers (CONTEXT S-39, applied to a list instead of a figure). THE FIRST VERSION OF THIS GOT THAT WRONG: the comment said only successful resolves were cached and the code cached the empty list anyway. TestArtifactChoices_FailureIsNotCached caught it before it shipped — which is the argument for writing the test that asserts the comment, and the same class this session spent the day closing. go build/vet/test green, go test -race clean, run separately from this commit.
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.
