- **The deb and rpm reach packages.arasaka.software from this repository's own release job.** On tags,
-  `.gitea/scripts/packages.sh` runs on the `nuvola` runner (host mode, user `gitea-runner`, which owns
-  `/var/www/packages.arasaka.software`). It imports the org secret `PACKAGES_SIGNING_KEY` into a throwaway
-  `GNUPGHOME`, refuses any key but `F92C166E…3FB2`, signs the rpm in place, hard-links the current pool into a new
-  `.snap/` folder, adds this version, keeps the newest five, rebuilds and signs the apt (`InRelease`, `Release.gpg`)
-  and rpm (`repomd.xml.asc`) metadata, carries over the files the previous `repomd.xml` named so a client mid-refresh
-  still finds them, swaps the `apt` and `rpm` links, rewrites `SHA256SUMS.txt` for the signed rpm, and checks the live
-  site. Never copy a package over a pool file: the pools are hard links into older snapshots, so it is `rm` then `cp`.
-  `PACKAGES_ROOT` and `PACKAGES_KEEP` exist for a test against a copy. YoloCICD, which used to do this, was erased on
-  23 Oct 2026. `packaging/arasaka-repository.sh` is written into both maintainer scripts by `tools/release.cs`; it is
-  now maintained here by hand, and any change to a file it writes needs the old content's SHA-256 kept in
-  `arasaka_repository_known`, or installed copies are treated as edited by hand and left alone. The package owns
-  `/usr/share/arasaka-repository/meweb`, the marker that keeps the repository configured while any Arasaka package
-  is installed. The signing key's only copies are that secret and the owner's Nextcloud backup.
- **The APK reaches an F-Droid repository on packages.arasaka.software from the same job** (31 Oct 2026), after the
-  release is published, so the repository can lag the release page but never lead it. `.gitea/scripts/fdroid.sh`
-  installs fdroidserver into `tools/fdroid` (cached like the JDK) with uv from `setup.json` and the hash-locked
-  `packaging/fdroid/requirements.txt`, because the box has no `ensurepip` and the apt package would bring 242 others.
-  The environment is made at the cache's real path (`pwd -P`) and rebuilt whenever `fdroid --version` fails: its
-  scripts carry the absolute path they were made at, `tools/fdroid` is a symlink from a workspace that can move, and
-  0.15.1's step failed with `fdroid: not found` on exactly that.
-  It signs the repository with the APK's own key (`MEWEB_KEYSTORE_B64` and `MEWEB_KEYSTORE_PASS`, alias `meweb`), so
-  the F-Droid fingerprint is the certificate's `5F52CFF4…FDF846` and there is no second key to lose; it refuses any
-  other. It builds a new snapshot in
-  `/var/www/packages.arasaka.software/.fdroid/` from the live one (the APKs as hard links, so `rm` then `cp` as above;
-  the metadata, `apkcache.json` and the previous `index-v2.json`, which is where fdroidserver reads each APK's first
-  date), adds this version, keeps the newest three, runs `fdroid update`, deletes `repo/status/` (it names the

+- **packages.arasaka.software is fed from outside this repository** (since 1 Nov 2026). The private repository
+  `thepra/packages.arasaka.software` lists this app in `apps/meweb.yml`, reads every `v*` release from the Releases
+  tab every 15 minutes, and publishes the newest five debs and rpms, the newest three APKs in the F-Droid repository
+  and the newest Windows and macOS files under `/download/meweb/`, all signed with keys that live as `thepra`'s own
+  secrets. Its README is the reference. What this repository still owes it:
+  - **The release must carry every file named in that entry and list each in `SHA256SUMS.txt`**, or the publisher
+    leaves the version out and keeps serving the previous one. Renaming a release file means changing `apps/meweb.yml`
+    in the same hour.
+  - **The rpm is signed here, before the release is published**, by `.gitea/scripts/sign-rpm.sh` with the Arasaka org
+    secret `PACKAGES_SIGNING_KEY` (it refuses any key but `F92C166E…3FB2`), which then rewrites `SHA256SUMS.txt`, so
+    the README's promise holds for the file on the release page too; the publisher sees the signature and keeps it.
+  - **The store listing is `fastlane/metadata/android/`** (`en-US` and `it-IT`: name, short and full description,
+    icon, banner, the six screenshots from `tools/Screenshots --store`), in Google Play's layout. The publisher reads
+    it from `master`, not from a release tag, so F-Droid shows a change within a quarter of an hour. The banner is
+    drawn by `Arasaka/app-stores`' `listing/banner.py meweb`. The F-Droid repository's own settings and icon live in
+    the publisher's repository.
+  - **The APK's signing key also signs the F-Droid index**, so `MEWEB_KEYSTORE_B64` exists twice: here, to sign the
+    APK, and as `thepra`'s `FDROID_KEYSTORE_B64`. The publisher refuses an APK signed by anything but `5f52cff4…f846`.
+  - `packaging/arasaka-repository.sh` is written into both maintainer scripts by `tools/release.cs`; it is
+    maintained here by hand, and any change to a file it writes needs the old content's SHA-256 kept in
+    `arasaka_repository_known`, or installed copies are treated as edited by hand and left alone. The package owns
+    `/usr/share/arasaka-repository/meweb`, the marker that keeps the repository configured while any Arasaka package
+    is installed. The portal app (`arasaka.software`, `arasaka-portal`) carries a byte-identical copy; change both.
 - **The server cannot ping**: `NoNewPrivileges` drops `ping`'s file capability and `ping_group_range` is closed, so
  the trace back to a caller uses `tracepath` (UDP, unprivileged) and keeps only public hops outside `Probe:Refuse`,

@@ -10,6 +10,49 @@ only MeWeb needs start at **#120**.

 Scope: `src/`, `tools/`. Out of scope: generated files (`obj/`, `*.g.cs`), third-party trees, the licence text.

+## House rules
+
+The owner's rules for every .NET project (`~/RiderProjects/HouseRules/RULES.md`, repo `Arasaka/HouseRules`) apply
+here. `Arasaka.HouseRules.Analyzers` (a `GlobalPackageReference` in `Directory.Packages.props`) reports the checkable
+ones as `HRxxxx` warnings, they are listed in `WarningsAsErrors`, and `tools/ci.sh` builds with `-warnaserror` too.
+MeWeb builds with none and carries no suppression. Applied to MeWeb:
+
+- **Coding style:**
+  - `var` for every local, `var x = default(T)` when there is no value yet (HR0001, #92).
+  - `IOptionsMonitor<T>.CurrentValue` (HR0002, #87).
+  - Primary constructors, using the parameters directly (HR0004, #1).
+    - Work a constructor used to do becomes a field initializer through a static helper (`RegistryWriter.Reserve`).
+    - A collection built from instance methods is a `field ??=` property (`MainViewModel.Cards`, `Shared`).
+  - A `CancellationToken` last on every method that returns a task, passed down (HR0003, #88).
+    - Relay commands take one.
+    - Where an API takes none, the wait takes it (`SetTextAsync(link).WaitAsync(ct)`).
+    - Best-effort and fire-and-forget work passes `CancellationToken.None` on purpose.
+- **DTOs:**
+  - `View*` responses, `*Request` create/update requests, `*Form` other input (HR0010 over `MeWeb.Shared`, #34).
+  - `Show*` booleans and `*Formatted` strings for display (#44).
+  - Lists are `= []` (HR0006, #75), and strings have no `= string.Empty` default (HR0005, #89).
+- **Server:**
+  - Routes live only in `Endpoints` (#9).
+  - A service that can refuse returns `WebResult<T>` (`MeWeb.Shared`). `Invalidate(reason)` answers 400; 403 and
+    404 are passed explicitly. The endpoint answers through `Answer(context, result, type)`: the data on success,
+    otherwise a `ViewRefusal` with its `Reason`, plus `Retry-After` when `RetryAfterSeconds` is set.
+  - Services take the caller's address from the endpoint, never `IHttpContextAccessor` (HR0008, #86).
+  - **Status codes** (owner, 2026-11-10):
+    - 400 for every refusal: bad ports, shape, size, busy, too many.
+    - 403 for a caller the probe will not serve (`not-public`, `other-address`) and a delete token that does not match.
+    - 404 for an unknown ticket or submission.
+    - Nothing answers 409, 413, 429 or any 5XX (HR0007), and MeWeb has no exception.
+    - Clients read `ViewRefusal.Reason`, never the status. Installed apps up to 0.15.4 read 429 on the speed download,
+      so until they update a limited speed test shows as "couldn't measure" rather than "limited".
+- **Client:** `ServerProbe` returns the same `WebResult<T>` and never throws (#27). A transport failure is the refusal
+  `unreachable`, and a failure without a body is `http-<status>`.
+- **Numbers:** formatted only by `NumbersExtensions` (`MeWeb.Shared`) and `Texts` (`MeWeb.App`) (HR0011).
+  - `NumbersExtensions` holds the invariant values that fill a localized template: `ToOneDecimal`, `ToWholeMegabytes`.
+  - `Texts` holds what the App formats in the reader's culture: money and dates.
+- **JSON:** one source-generated context per assembly (#84).
+- **Not applicable:** the `.razor` rules (HR0101–HR0106, HR0201), since the App is Avalonia. Their counterparts are
+  #27, #43, #44 and #93. `Localizer.Instance[key]` already returns a string (#91).

thepraandClaude Opus 5.5	b4bd102b17	The release and knowledge tools follow the house rules too Release / Every platform, the server, the release (push) Successful in 7m29s Details Build / Desktop, server and tools (push) Successful in 46s Details Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01W4YtEJrgxG12Pc39Fai8Bd	2026-11-10 06:48:23 +01:00
thepraandClaude Opus 5.5	7cad7a32dd	me-web? 0.16.0: current Avalonia and .NET libraries Build / Desktop, server and tools (push) Successful in 1m23s Details Release / Every platform, the server, the release (push) Failing after 8s Details Built with SDK 10.0.403 on Avalonia 12.1.6, the current .NET 10 libraries and QRCoder 1.8.1. On Android the splash screen library moves to 1.2 together with the lifecycle libraries it needs. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01W4YtEJrgxG12Pc39Fai8Bd	2026-11-10 06:44:44 +01:00
thepraandClaude Opus 5.5	d408edea98	House rules: the build checks them, and every refusal from the server answers 400, 403 or 404 Build / Desktop, server and tools (push) Successful in 1m8s Details The server no longer answers 409, 413 or 429: a busy probe, a share or upload that is too large and a request over the limit now answer 400 with the same reason as before, and still say when to try again. The app reads the reason, so nothing changes for it; versions up to 0.15.4 report a limited speed test as unmeasured until they update. The app's commands can now be cancelled all the way down, and the house rules are written into PATTERNS.md and checked on every build, Android included.

thepraandClaude Opus 5.5	5b2210a8a7	F-Droid page: screenshots, a banner and a fuller description Build / Desktop, server and tools (push) Successful in 1m5s Details The app's page in F-Droid had a stretched icon across the top, no pictures and two lines of text. It now shows six screenshots in English and Italian (the opening screen, what you can host, the path from the phone to the internet, one finding explained, a check under way and exactly what sharing would send), a banner, the icon at full size and a description of what the app checks and what stays on the phone. The screenshots are drawn from an invented connection, not the computer that makes them: documentation addresses, a made-up provider, nothing that belongs to anyone. One command redraws them after a change to the screens: dotnet run --project tools/Screenshots -- --store. The listing is in the layout Google Play uses, so the same files will serve there.

thepraandClaude Opus 5.5	8c079e43c9	me-web?: new versions show up in the software centre within a quarter of an hour Build / Desktop, server and tools (push) Successful in 1m8s Details The Arasaka repository that “me-web?” adds told software centres such as Discover that its list of packages stays good for six hours, so a new version could stay out of sight for that long, even after pressing Refresh. It now says fifteen minutes. The change reaches a computer with the next version of “me-web?”; a repository file someone edited by hand is left as it is.

thepraandClaude Opus 5.5	ad33779356	Release notes come from app-stores' changelog action, into the deb and rpm too Build / Desktop, server and tools (push) Successful in 1m12s Details The release's "What's new" is now written by the shared generator every Arasaka release uses, from the same commit messages and with the same "me-web? x.y.z:" prefix removed; the deb and rpm carry it as their changelog (apt changelog, rpm --changelog), and CHANGELOG.md is attached beside the files and listed in SHA256SUMS.txt.

The release still signs the rpm on its own page with the Arasaka key, as the README promises, and the F-Droid listing stays in packaging/fdroid/metadata, read at each tag.

thepraandClaude Opus 5.5	0c722c21d4	me-web? 0.15.4: a desktop with a wireless mouse is no longer taken for a laptop Build / Desktop, server and tools (push) Successful in 1m14s Details Release / Every platform, the server, the release (push) Successful in 8m38s Details - On Linux, a desktop computer with a wireless mouse, keyboard, headset or game controller was described as a laptop, with the advice to use a small always-on computer instead, because the battery inside the mouse was counted. Only the computer's own battery counts now. - The mail card now leads with what big mailboxes care about most: when your address's reverse name looks like a home line, or there is none, that comes first. A blocklist that names your provider's whole network is still shown below it. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>	2026-10-31 23:24:15 +01:00
thepraandClaude Opus 5.5	e112c1dc1e	A daily job keeps the tools behind the deb and rpm repositories current Build / Desktop, server and tools (push) Successful in 1m28s Details The box updates the tools that build packages.arasaka.software every morning, and packages.yml rebuilds and re-signs the apt and rpm repositories when those tools change, so a broken update shows up the same morning, not at the next release. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01T9uhaCTSycTh1r8At679Pz	2026-10-31 22:52:24 +01:00
thepraandClaude Opus 5.5	10a85e6bc5	A daily job keeps the F-Droid tools current and rebuilds the repository when they change Build / Desktop, server and tools (push) Successful in 51s Details - Every day the F-Droid repository's tools are checked for a newer version that has been out for at least two weeks. When there is one, or when the app's listing changed, the repository is rebuilt with it, and releases use it only once that worked, so a faulty update of the tools can never hold up a release. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01T9uhaCTSycTh1r8At679Pz	2026-10-31 11:03:52 +01:00
thepraandClaude Opus 5.5	cafa40decf	The F-Droid repository is built with the newest F-Droid tools at every release Build / Desktop, server and tools (push) Successful in 1m9s Details - Each release now installs the newest version of F-Droid's own tools that has been out for at least two weeks, instead of one fixed version, so the repository keeps up with F-Droid without anyone updating it by hand.
