+# Contributing to Frame Control
+
+This guide exists to save both sides time. The process is borrowed from
+[pi](https://github.com/badlogic/pi-mono/blob/main/CONTRIBUTING.md).
+
+## Just want to report something?
+
+Use the [feedback form](https://frame-control.pages.dev/feedback/). It needs no
+GitHub account, and what you send becomes an issue here that stays open.
+
+## The One Rule
+
+**You must understand your code.** If you can't explain what your change does
+and how it interacts with the rest of the app, your PR will be closed.
+
+Using AI to write code is fine. Submitting AI-generated slop you don't
+understand is not.
+
+## Contribution gate
+
+Issues and PRs opened on GitHub by new contributors are auto-closed by default.
+A maintainer reviews auto-closed issues regularly and reopens worthwhile ones.
+Issues that don't meet the quality bar below won't be reopened or get a reply.
+
+Approval happens through maintainer replies on issues:
+
+- `lgtmi`: your future issues won't be auto-closed
+- `lgtm`: your future issues and PRs won't be auto-closed
+
+The word must be at the start of the reply (optionally after one or more
+`@username` mentions) or at the end. Only `lgtm` lets you open PRs. Approved
+people are listed in [`.github/APPROVED_CONTRIBUTORS`](.github/APPROVED_CONTRIBUTORS).
+
+## Quality bar for issues
+
+Use one of the issue templates, and keep it short, concrete and worth reading.
+
+- If it doesn't fit on one screen, it's too long.
+- Write in your own voice. If you must use an LLM, say so in a clearly labelled
+  follow-up comment.
+- State the bug or request clearly, and why it matters.
+- For bugs, include your OS, your SteamOS build (Steam Settings → System), and
+  the server log (**Frame → Show Server Log** in the app).
+- If you want to implement the change yourself, say so.
+
+## Before opening a PR
+
+Don't open a PR until a maintainer has approved you with `lgtm`. Open an
+[idea or contribution proposal](https://github.com/saphid/frame-control/issues/new?template=idea.yml)
+first.
+
+Then check your change:
+
+```sh
+python3 -m unittest discover -s tests   # server tests; no headset needed
+node --test site/test/*.test.mjs        # website feedback function
+```
+
+Say what you tested, and whether you tried it on a real Steam Frame.
+
+## Blocking
+
+If you ignore this document twice, or spam the tracker with agent-generated
+issues, your GitHub account will be blocked from the repo.
+
+## Why auto-close?
+
+This is a hobby project with one maintainer. Auto-closing is a buffer against
+burnout and tracker spam: issues get reviewed on the maintainer's schedule, and
+the good ones are reopened. Short, concrete, reproducible reports and thoughtful
+contributions are welcome.

+# Announcing changes
+
+How we tell people about Frame Control features and fixes as they merge. The
+same few sentences feed the X post, the release notes and the website, so they
+are written once, in the pull request, while the change is fresh.
+
+## What gets announced
+
+| Kind | Announce? | Example |
+|---|---|---|
+| **New** — something you can now do | Yes, its own post | Stream Mac windows into the Frame as panels |
+| **Better** — something existing got noticeably easier, faster or wider | Yes, its own post or a roundup | APKs install without the Android SDK |
+| **Fixed** — something broken that users hit | Yes if people reported it or it blocked a flow; otherwise the next roundup | Mac mirror showed a zoomed-in corner |
+| **Release** — a tagged build | Always, one post linking the release | Frame Control 0.3.1 |
+| Tests, refactors, CI, docs-only, website polish | No | Fake Frame tests, screenshot crop |
+
+If a change isn't worth a sentence to someone who owns a Frame, it isn't
+announced.
+
+## The voice
+
+Write it the way the README and release notes already read.
+
+- **Lead with what the person can now do**, in their words: "Install older
+  versions of an app when the newest won't run on the Frame", not "Add APK
+  version fallback resolver".
+- **Plain and specific.** Name the thing, give the number: "about 30 fps",
+  "4,500 apps", "up to 8 older versions". No "blazing", "game-changing",
+  "excited to announce", "huge", or exclamation marks.
+- **Say where it works.** Platforms and what it was tested on, briefly:
+  "Tested on a real Frame from macOS 27." Don't claim what wasn't tested.
+- **Say the catch.** If it needs a setup step, an unsigned build, or only works
+  on one OS, say so in the same post.
+- **Sentence case**, full sentences, British spelling to match the docs.
+  Contractions are fine.
+- **No emoji in the text.** One image, GIF or short clip carries the tone
+  instead. The only symbol is the kind label below.
+- **Unofficial, always.** Never imply Valve made or endorses it. Say "Steam
+  Frame" for the headset and "Frame Control" for the app.
+- **Credit people.** If a user reported the bug or suggested the feature and is
+  happy to be named, thank them by handle.
+
+## The formats
+
+Every announceable PR ends with an `## Announcement` section holding these.
+The reviewer checks it like code.
+
+### 1. The post (X, and any other social account)
+
+```
+<Kind>: <what you can do now, one sentence>
+
+<one or two sentences: how it works, the catch, or what it was tested on>
+
+<link>
+```
+
+- `<Kind>` is `New`, `Better` or `Fixed`.
+- 280 characters maximum including the link (X counts any link as 23).
+- One link: the release if it has shipped, otherwise the PR.
+- One visual when the change is visible: a screenshot from the app, a GIF, or a
+  short clip from the headset. Alt text describes what it shows.
+- No hashtags, except `#SteamFrame` on releases and on posts about something
+  new, because people search for it.
+
+### 2. The release-note line
+
+One bullet under **New in x.y.z**, same as the current release notes: the
+first half of the post's first sentence, no kind label, no link.
+
+### 3. Release post
+
+```
+Frame Control <version>: <the headline change>
+
+<one sentence on the headline change>. Also: <two or three short items>.
+
+Windows, macOS and Linux: <release link>
+#SteamFrame
+```
+
+The release title on GitHub uses the same `Frame Control <version>: <headline>`
+line, as 0.3.0 and 0.3.1 already do.
+
+### Roundups
+
+Small fixes that don't earn their own post wait for a roundup, posted with the
+next release or when three or more have piled up:
+
+```
+Fixed in Frame Control this week:
+- <fix>
+- <fix>
+- <fix>
+
+<link>
+```
+
+## Examples from what has already merged
+
+**#11, older APK versions**
+
+```
+New: when an Android app is too new for the Frame, Frame Control now offers
+older versions that will install.
+
+It checks F-Droid, its archive and IzzyOnDroid, and verifies each download
+before it goes on the headset.
+
+https://github.com/saphid/steam-frame/pull/11
+```
+
+**#8, Mac mirror fixes**
+
+```
+Fixed: mirroring your Mac into the Steam Frame now fits the whole desktop in
+the panel, asks for the right password, and shows the cursor.
+
+Tested end to end on a real Frame from macOS 27.
+
+https://github.com/saphid/steam-frame/pull/8
+```
+
+**v0.3.1**
+
+```
+Frame Control 0.3.1: install APKs without the Android SDK
+
+Frame Control now reads APK files itself, so there's nothing extra to install.
+Also: Linux and Windows game sideloading, and one-click install links.
+
+Windows, macOS and Linux: https://github.com/saphid/steam-frame/releases/tag/v0.3.1
+#SteamFrame
+```
+
+## Posting
+
+Nothing is posted without a person approving it. The flow is:
+
+1. The PR carries its `## Announcement` section.
+2. On merge, the post is drafted from that section (manually for now).
+3. Alex approves or edits it, then it's posted from the project account.
+4. Replies and questions that turn out to be bugs become GitHub issues labelled
+   `feedback`, same as the website form.

+**Games** (installed games, sideloaded titles, getting games), **Android** (apps,

Its bundled server listens on `127.0.0.1:3773` and shows up in onboarding as the `frame` computer, with `passwordStore: gnome-libsecret`. The image has no agent CLI and no `node`. Agents run through the LAN CLIProxyAPI (`llm-proxy.lan:8317`, which resolves on the Frame). Claude Code 2.1.283 comes from `claude.ai/install.sh`, and Codex 0.157.1 from the `codex-aarch64-unknown-linux-musl` release tarball, both into `~/.local/bin`. `with-cliproxy` and a mode-600 `~/.config/cliproxyapi/secrets.env` are copied from the Mac.

Last resort is a full re-image, two ways: (1) USB: write `steamframe-oobe-repair-<build>.img.bz2` to an 8 GB+ USB-C stick (Balena Etcher on the Mac), pick `Boot from USB`, then use "Wipe Device & Install SteamOS" / "Repair SteamOS" (keeps games and personal content) from the recovery desktop; (2) cable/EDL: `steamframe-oobe-repair-qdl-<build>.tar.gz`, run `flash.sh` (Linux) or `flash.cmd` (Windows), then with the Frame off for 10 s hold Power + Vol Up + Vol Down for 10 s and plug it in; it reflashes and reboots.

 | **Boot loop cause: the SteamVR health check.** `steamvr.service` runs `/usr/share/deckard/steamvr-health-check`, which appends `frog:glasses:` to `$XDG_RUNTIME_DIR/steamvr-short-session-tracker` on every failed or <10 s SteamVR run. At 3 it runs `steam-health-check --repair-now`, which **deletes all of `~/.local/share/Steam` (games, login, Developer Mode) and `~/.steam`**, keeping only `registry.vdf`. At 4 it also tries `steamos-bootconf set-mode reboot-other` (fails as the user: `bootenv: Permission denied`). SteamVR normally fails 1–2 times per boot while it waits for the Steam client (`SteamAPI_InitEx failed … Steam is probably not running`, then `fatal stalled cross-thread pipe`). Once Steam has been wiped, it has to re-download a ~210 MB client on every boot, so SteamVR keeps failing, Steam keeps getting wiped and the Frame reboots, in a loop. Also, the Steam updater can deadlock at `Installing update...` (main process blocked writing to the `-child-update-ui` process, which is stuck in `drm_syncobj_array_wait_timeout`). Killing only the `-child-update-ui` process lets the install finish (`package/*.installed` appears). **Fix without sudo:** over USB-C ADB (`adb -s frame shell` works as `steamos` while the Frame is looping; SSH is refused once Developer Mode is lost), truncate both `/run/user/1000/steam{,vr}-short-session-tracker` files and `chmod 444` them (the health check then logs `Permission denied` and does nothing; this is tmpfs, so it resets on reboot). Unstick the updater if needed, let Steam finish installing, then hold Power 10 s and start the Frame normally. `systemctl reboot` over ADB needs interactive auth. After the fix, sign in to Steam and turn Developer Mode back on. **Verified 2026-09-26**, BUILD_ID 20260922.6101926, slot B (clean boot: 0 SteamVR failures, SSH and Tailscale back). | Diagnosing a boot loop |

+# Frame Control for iPhone
+
+The iPhone (and iPad) app does what the desktop app does, from the phone:
+headset view and live video, battery and status, screenshots, Steam games,
+Android apps and their display settings, sideloading, files, clipboard,
+Flatpaks, and power. Source: [`ios/`](../ios).
+
+## How it works
+
+An iPhone can't run Python or `ssh`, but the Frame can. So the app:
+
+1. connects to the Frame over SSH itself (the [Citadel](https://github.com/orlandos-nl/Citadel)
+   Swift SSH library), with its own ed25519 key from the Keychain;
+2. copies Frame Control's server and helpers (`ios/scripts/make_frame_bundle.py`,
+   under 1 MB) to `~/.cache/frame-control/<version>` on the Frame, once per version;
+3. starts `ui/server.py` there with `FRAME_LOCAL=1`. It listens only on the
+   Frame's own 127.0.0.1, and it stops when the phone disconnects (`--exit-on-eof`);
+4. tunnels to it through the SSH session and shows the same page as the desktop
+   app, in a web view. The page carries a fresh key each session, which the
+   server requires on every request.
+
+With `FRAME_LOCAL=1`, every `ssh frame COMMAND` the server runs goes to
+`ui/local-bin/ssh`, which runs the command on the Frame directly (rsync uses it
+as its transport too), so the desktop and phone share one code path. Android
+display settings use `podman exec` into each Lepton container instead of adb,
+which the Frame doesn't have.
+
+Nothing is left running on the Frame after the phone disconnects; the copied
+files stay in `~/.cache/frame-control` (delete it any time).
+
+## Pairing
+
+On the Frame, turn on Developer Mode and set a user password (Steam Settings →
+System, then Developer → Set User Password). In the app, enter the headset's
+address (`frame.local`, its IP, or its Tailscale name) and that password once.
+The app adds its own key to `~/.ssh/authorized_keys` and remembers the Frame's
+host key; the password isn't saved. If you already reach the Frame over SSH,
+**Or add the key yourself** shows the phone's key to paste into
+`authorized_keys`, and connects without a password.
+
+Valve's tap-to-approve devkit pairing isn't used: it only takes RSA keys, and
+the Frame's OpenSSH 9.7 rejects the SHA-1 RSA signatures the Swift SSH library
+makes.
+
+## What's different on the phone
+
+| Desktop | iPhone |
+|---|---|
+| Drop files anywhere | Tap **Send to Frame** (or Add a game) and pick files; folders need zipping |
+| Screenshots save to `~/Pictures/SteamFrame` | Save opens the share sheet: Save Image puts it in Photos |
+| SSH and SFTP open a terminal | They open an app that handles `ssh://` / `sftp://` (Blink Shell, Termius) |
+| Steam Link, remote desktop | Open the Steam Link and Windows App apps |
+| Sleep, restart, shut down ask in a terminal | The page asks for the Developer Mode password |
+| Compatibility reports kept on the computer | Kept on the Frame (`~/.local/share/Frame Control`) |
+
+## Building
+
+```sh
+cd ios
+xcodegen generate          # after changing project.yml
+open FrameControl.xcodeproj
+```
+
+The build packs the Frame bundle from the checkout, so the phone always runs
+the page and server from the same commit. Running on a phone needs your own
+signing team in Xcode (Signing & Capabilities).
+
+## Verified
+
+<img src="img/iphone-tabs.jpg" alt="The four tabs in the iPhone app, connected to a Frame" width="900">
+
+In the iOS Simulator (iOS 26.5) against a real Frame, 2026-09-27: the app connected
+with its key, copied the bundle over SFTP, started the server on the Frame and
+showed all four tabs with live data. In the app's web view, Capture returned a
+headset still and Live played H.264 video at 31 fps (WebCodecs works in
+WKWebView). Through the app's tunnel: status, games, Steam library, Android apps,
+screenshots, a file upload (checked on the Frame), a background install job, and
+the power password check (a wrong password is refused). The server on the Frame
+exits within seconds of the app closing.
+
+Against Valve's own Steam Frame OS (SteamOS 0.3.0 build 20260922.5152327, the
+`rootfs-A` partition of the Frame recovery image, run with its own sshd; see
+[tests/frame-container](../tests/frame-container)), and a Holo Core stand-in:
+pairing with the password (key added with the right
+permissions, host key pinned, password stored nowhere), the power password
+check (a wrong or missing password refused; the right one reaches `systemctl`),
+a changed host key refused with "Pair with the Frame again", and a wrong
+pairing password reported the same way.
+
+Also verified in the Simulator against the Frame (2026-09-27): the setup screen
+found the Frame by itself over Bonjour (`frame · 192.168.1.237`); a paired app
+waiting for a sleeping Frame connected 4 s after it answered; an upload from the
+app's web view landed in `~/Downloads`; the share sheet offers Save Image
+(needs `NSPhotoLibraryAddUsageDescription`, now declared); an install link opens
+the confirm dialog and downloads nothing until Install; Steam Link without the
+app installed opens its App Store page.
+
+Things iOS asks the first time: **Local Network** (tap Allow, or the app can't
+see the Frame), and **Paste** when you send the iPhone's clipboard (tap Allow
+Paste, or set Settings → Apps → Frame Control → Paste from Other Apps → Allow).
+Sending text to the Frame's clipboard needs the desktop panel open in the
+headset, as on the desktop app.
+
+Not yet exercised: Android display changes through podman (no Android app was
+running), a real sleep/restart/shut down on the Frame, and a physical iPhone.
+
+Debug builds have Simulator test hooks (`FRAME_TEST_HOST`, `FRAME_TEST_PAGE`,
+`FRAME_TEST_JS`, and the tunnel URL in the app's Caches folder); release builds
+don't.

+
+The partitions start at sector 34, not on MiB boundaries, so compute offsets
+from the table (sector × 512), not from rounded sizes. `rootfs-A` is **btrfs**
+(label `rootfs-A`, 9.2 GB of files), mounted read-only on the Frame.
+Its `/etc/os-release` says `NAME="SteamOS"`, `ID=steamos`, `ID_LIKE=arch`,
+`VERSION_CODENAME=holo`; the running system reports version 0.3.0, variant
+`vr`, build **20260922.5152327**, which is a different number from the
+`5153644` in the file name. Our headset reports build 20260922.6101926.
+
+Inside, it matches a real Frame:
+
+- User `steamos` (uid 1000) is in `wheel` (gid 998), and sudoers has
+  `%wheel ALL=(ALL) ALL`, so sudo asks for the Developer Mode password.
+- `sshd_config` includes `sshd_config.d/*.conf`, uses `.ssh/authorized_keys`
+  plus `AuthorizedKeysCommand /usr/bin/userdbctl ssh-authorized-keys %u`,
+  and sets `KbdInteractiveAuthentication no` and `UsePAM yes`. So sshd offers
+  `publickey,password`, the same as the headset.
+- `/usr/bin` has `sshd`, `sudo`, `python3` and `podman`.
+
+Get just the root filesystem without unpacking the whole 5.8 GB image (the
+partition's start and size, in sectors, come from the table above):
+
+```sh
+bzcat steamframe-oobe-repair-*.img.bz2 | tail -c +$((655394 * 512 + 1)) | head -c $((10485760 * 512)) > rootfs-A.img
+```
+
+A Mac can't mount btrfs; a Linux machine or VM can (`mount -o ro -t btrfs`).
+
+## Running it without the headset
+
+The image can't boot in a generic virtual machine: its kernel and bootloader
+are built for the Frame's Qualcomm Snapdragon 8 Gen 3 (**inferred**; not
+attempted). Its **userland** runs fine on any ARM64 Linux, which covers
+anything that talks to the Frame over SSH.
+
+[`tests/frame-container/frame-image.sh`](../tests/frame-container/frame-image.sh)
+extracts `rootfs-A`, mounts it read-only with a throwaway writable layer, and
+starts the image's own `sshd` on port 2223 (user `steamos`, a test password;
+`systemctl` only records requests). On a Mac, run it in Colima's ARM64 VM (see
+[tests/frame-container/README.md](../tests/frame-container/README.md)).
+**Verified 2026-09-27:** the iPhone app paired with it by password (the image's
+sshd logged `Accepted password`, then `Accepted publickey … ED25519`), ran
+Frame Control's server on the image's Python, and the image's sudo rejected a
+wrong power password and passed the right one to `systemctl`. Without the
+Frame's hardware there's no SteamVR, Steam client, battery or Lepton, so those
+parts stay untested this way.
+
+## Holo Core aarch64 (Valve and Collabora)
+
+The ARM64 port of Arch Linux that the Frame's SteamOS is built on, published as
+a preview in July 2026 ([Collabora's announcement](https://www.collabora.com/news-and-blog/news-and-events/building-an-arch-linux-aarch64-port-for-holo-core.html)).
+It's a base system and build environment, not the Frame's OS:
+
+- Source: `https://gitlab.steamos.cloud/holo/holo-core-aarch64-preview`
+- Packages: `https://holo-packages.steamos.cloud/holo-core-aarch64-preview/mash-20251118`
+- Container: `registry.gitlab.steamos.cloud/holo/holo-core-aarch64-preview/base-devel:latest`
+  (1.7 GB; `/etc/os-release` says "Holo core Aarch64 port (preview)"; `pacman`
+  installs OpenSSH 10.2, Python 3.13 and sudo from its repositories. Checked 2026-09-27.)
+
+[`tests/frame-container/Dockerfile`](../tests/frame-container/Dockerfile) builds a
+lighter Frame stand-in on it (a `steamos` user with a password and sudo, sshd
+with keys and passwords), handy when you don't have the 4 GB image.

+corner. (Verified 2026-09-27.)
 
-## Input and text entry without the virtual keyboard
+**Expect a Mac login prompt, not the VNC password.** macOS offers Apple's own
+authentication (RFB security type 30) ahead of plain VNC auth (type 2), and
+Remmina picks it. So Remmina asks for your **Mac account name and login
+password**; the "VNC viewers may control screen" password isn't used. To store
+the password without typing it in the headset, run on the Frame:
 
-- **A Bluetooth keyboard and mouse** paired to the Frame is the obvious way to
-  avoid the virtual keyboard. Road to VR says there are "only a few things
-  you'd actually want to do" on the Linux desktop unless you connect a
-  keyboard and mouse.
-  (Pairing a BT keyboard on the Frame is inferred from SteamOS; not verified.)
-- **Clipboard from the Mac**: `scripts/paste-to-frame.sh` (see
-  [file-transfer.md](file-transfer.md#clipboard)).
+```sh
+printf '%s' "$PASSWORD" | flatpak run org.remmina.Remmina \
+  --update-profile ~/.var/app/org.remmina.Remmina/data/remmina/mac-screen-sharing.remmina \
+  --set-option password
+```
+
+Remmina encrypts it into the profile with its own key, because there's no
+secret service in the SSH session. (Verified 2026-09-27.)
+
+### The Mac's cursor
+
+The mirror doesn't show the Mac's pointer, with either `showcursor` value.
+macOS keeps the pointer out of the picture it sends, and Remmina's cursor mode
+draws the cursor shape only at the Frame's own pointer, which doesn't follow
+the Mac trackpad. `scripts/mac-cursor-ring.lua` works around this: a
+[Hammerspoon](https://www.hammerspoon.org/) script that draws a ring around the
+Mac pointer as a real window, so it's part of the mirrored picture. Setup is in
+its header. (Verified 2026-09-27.)
+
+Going the other way, pointing a controller at the panel moves the Mac's mouse,
+because Remmina forwards input (`viewonly=0`).
+
+## C. Show the iPhone's screen inside the Frame
+
+iOS only shares its screen two ways: **AirPlay** (Screen Mirroring in Control
+Centre) or a **ReplayKit broadcast extension** in an app. Nothing else can
+capture it.
+
+| Option | What it takes | Confidence | Verdict |
+|---|---|---|---|
+| **UxPlay** (an open-source AirPlay receiver) on the Frame | Build it for aarch64 (no Flathub package; there's a Snap and distro packages), run it in `~` or a podman container, and advertise it over mDNS. The iPhone *and* the Mac then see "Frame" in Screen Mirroring, with nothing to install on either | **Inferred.** It runs on ARM64 Linux such as the Raspberry Pi ([UxPlay](https://github.com/FDH2/UxPlay)). Not tried on the Frame: needs mDNS registration and its ports (7000, 7001, 7100 and a UDP range) reachable | **Recommended to try first.** It's the only receiver-side option, and it covers the Mac too. The window shows in the Frame's Linux desktop panel |
+| A broadcast extension in Frame Control | ReplayKit sends the screen to a small extension (50 MB memory limit), which encodes H.264 and sends it through the app's SSH tunnel to the page, shown the same way as the Frame's live view in reverse | **Inferred** from Apple's ReplayKit docs | Full control and no network setup, but several days' work, and the picture only shows where Frame Control's page is open in the headset |
+
+## Input: type and point in the Frame from the Mac or iPhone
+
+**Verified 2026-09-27** on the headset: `steamos` is in the `input` group and
+`/dev/uinput` is `crw-rw-r-- root input`, so **our own code can create a
+virtual keyboard and mouse without sudo**. The Frame has no `python-evdev`,
+`ydotool`, `wtype` or KDE Connect; `kwin_wayland` and `plasmashell` run only
+while the desktop panel is open in the headset.
+
+| Option | Mac | iPhone | Notes |
+|---|---|---|---|
+| **A uinput keyboard and mouse in Frame Control's server** | ✓ | ✓ | **Recommended.** The server opens `/dev/uinput` with `ctypes` (standard library only) and the page sends key and pointer events through the tunnel it already has. On the phone: a trackpad area (drag to move, tap to click, two fingers to scroll) and the iOS keyboard for typing. On the Mac: a "control the Frame" mode that captures the keyboard and pointer (Esc to release). Uinput devices look like real hardware to the kernel, so libinput, KWin and gamescope should take them; [frame-voice](https://github.com/DeeJanuz/frame-voice) already types into a Frame through a uinput keyboard. **Untested**: which surfaces in VR (desktop panel, SteamVR dashboard, games, Android apps in Lepton) accept the pointer. About a day or two of work |
+| **Bluetooth keyboard and mouse** | – | – | Real hardware paired in SteamOS settings. The iPhone can't pretend to be a Bluetooth keyboard: iOS won't advertise the HID service ([Apple forums](https://developer.apple.com/forums/thread/733916)) |
+| **Deskflow** (formerly Input Leap / Barrier) | ✓ | – | Moves the Mac's own mouse and keyboard onto the Frame's screen edge. Flathub has an aarch64 build ([Flathub](https://flathub.org/apps/org.deskflow.deskflow)); on Wayland it needs the InputCapture/libei portal, and only works while Plasma is running. No iPhone client |
+| **KDE Connect** | ~ | ✓ | Its iOS app has a remote touchpad and keyboard, but the Frame would need KDE Connect installed (not on Flathub; `pacman` on a read-only root). More moving parts than the uinput route |
+| **Remmina / Steam Link / RDP** | ✓ | – | Input only reaches the streamed session, not the headset's own apps |
+
+Other ways to get text in:
+
+- **Clipboard from the Mac**: `scripts/paste-to-frame.sh`, or Frame Control's
+  clipboard box (see [file-transfer.md](file-transfer.md#clipboard)). Needs
+  the desktop panel open.
 - **RDP session**: Windows App syncs the clipboard with xrdp, but only inside
   that RDP session.

+# Testing
+
+Frame Control is tested in three layers, from fast and fake to slow and real.
+A fourth, a SteamOS VM, may come later ([issue #6](https://github.com/saphid/steam-frame/issues/6)).
+
+| Layer | Runs | Needs | Covers |
+|---|---|---|---|
+| Unit tests (`tests/*.py`) | `python3 -m unittest discover -s tests` | Nothing | Parsing, validation, request guards; SSH and HTTP are mocked |
+| Fake Frame (`tests/e2e`) | `scripts/e2e.sh` | Linux with Docker | The real server and scripts against a container that behaves like a Frame |
+| Headset smoke test | `scripts/frame-smoke.sh` | A Frame on the `frame` alias | Install, launch and remove on the real device, recorded with its BUILD_ID |
+
+## Unit tests
+
+```sh
+python3 -m unittest discover -s tests
+```
+
+About 120 tests, a few seconds, on Python 3.9 and newer. GitHub Actions runs
+them on macOS, Windows and Linux. They don't pick up `tests/e2e`.
+
+## The fake Frame
+
+`tests/fakeframe/` builds a container that stands in for the headset, and a
+second one for the computer Frame Control runs on. `scripts/e2e.sh` builds
+both, starts them with `docker compose`, runs `tests/e2e` in the host
+container and takes everything down, exiting with the tests' status:
+
+```sh
+scripts/e2e.sh                                   # everything, about 2 minutes plus the first build
+scripts/e2e.sh test_titles                       # one module
+scripts/e2e.sh test_faults.Faults.test_disk_full # one test
+FAKEFRAME_KEEP=1 scripts/e2e.sh                  # leave it running afterwards
+```
+
+It needs a Linux host with Docker and `docker compose`, and zsh. The images
+are `fakeframe-frame` and `fakeframe-host`; the compose project, network and
+volumes are `fakeframe-e2e*`. CI runs it on a native arm64 runner
+(`ubuntu-24.04-arm`, the `e2e` job in `.github/workflows/checks.yml`).
+
+The host container exists because OpenSSH reads `~/.ssh/config` from the
+passwd home directory, not `$HOME`. There, `ssh frame` reaches the fake Frame
+through the same `Host frame` block `ui/frame_connect.py` writes, the
+repository is mounted read-only at `/repo`, and each test module starts the
+real `ui/server.py` (Python 3.9) and talks to it over HTTP with the headers
+its guards want.
+
+### What's real and what's fake
+
+| On the fake Frame | |
+|---|---|
+| Arch Linux (`archlinux:base`, or Valve's Holo Core aarch64 preview on arm64), user `steamos`, `/etc/os-release` with BUILD_ID 20260922.6101926 | Real OS, Frame's identity |
+| `sshd` with key and password logins, `rsync`, `python3` | Real |
+| Valve's steamos-devkit-service on port 32000 and its hooks, vendored unmodified in `tests/fakeframe/steamos-devkit-service` | Real; only its `dbus` import (for mDNS through systemd-resolved) is a stand-in that logs the registration |
+| Valve's devkit-utils, copied over by Frame Control itself | Real |
+| **fakesteam**: `~/.steam/steam.pid`, `steam.token` and the `steam.pipe` FIFO; answers `approve-ssh-key`, `create-shortcut`, `run-game`, `list-shortcuts` and `delete-shortcut` with the response files devkit-utils waits for; takes `steam://rungameid`, `install` and `store` URLs | Fake |
+| DevTools on `127.0.0.1:8080` with a `SharedJSContext` target. The JavaScript Frame Control sends runs for real in Node against stand-in `SteamClient`, `appStore` and `downloadsStore` objects (`cef_shim.js`), so async functions, optional chaining and `Map`s behave as in Steam's CEF | The JS engine is real; the objects are fake |
+| `steam`, `wpctl`, `flatpak`, `podman`, `nmcli`, `qdbus6`, `gamescopectl`, SteamOS's `steamos-enable-sshd` helper, and Lepton's launcher | Stubs that record their calls |
+| Battery, charger and thermal zones under `/sys/class` | Files the supervisor writes. `/sys` is read-only in a container and Docker's AppArmor profile refuses writes under it, so each folder is a volume mounted twice: over `/sys/class/...` for `frame_status.py` to read, and under `/var/lib/fakeframe/sys` for the supervisor to write |
+| `vrserver` and `plasmashell` | Renamed `sleep` processes, so the status page and the clipboard find them |
+
+Every fake behaviour copied from the device has a comment citing the doc or
+observation and the BUILD_ID it came from; anything not seen on a headset is
+marked as a guess. The fake keeps its state in `/var/lib/fakeframe/state.json`
+(shortcuts, devkit titles, compat tool mapping, launches, pairing requests,
+Lepton instances, volume, Flatpaks, clipboard) and logs stub calls to
+`calls.jsonl` beside it.
+
+Native programs really run: a launched aarch64 title executes on an arm64
+host, and an x86-64 one on x86-64 (the container shares the host's kernel).
+Proton titles are recorded with the command Steam would run, not run.
+
+### Fault switches
+
+`fakeframe-ctl` works over SSH (`ssh frame fakeframe-ctl help`) and from the
+host container (`FAKEFRAME_CTL=http://fakeframe:9999`), so a test can flip a
+switch while SSH is down:
+
+| Command | Effect |
+|---|---|
+| `pairing on\|off` | Steam's **Pair new host** screen open or not; off gives the device's 403 text |
+| `answer approve\|deny\|timeout` | How the pairing prompt is answered |
+| `steam on\|off` | Steam client running (pid file, pipe, DevTools) |
+| `sleep on\|off` | Headset asleep: ports 22 and 32000 accept and never answer, so SSH times out |
+| `sshd on\|off` | sshd stopped: new connections are refused, open ones stay |
+| `devkit-service on\|off` | Port 32000 closed |
+| `disk-full on\|off` | Fills the small (64 MB) filesystem on `~/devkit-game` |
+| `runtime NAME installed\|missing` | Proton, the Steam Linux Runtimes, Lepton |
+| `battery KEY=VALUE...` | e.g. `capacity=15 status=Discharging current_now=-900000` |
+| `keys harness\|none`, `authorized-keys` | Set or read `~/.ssh/authorized_keys` |
+| `reset`, `state`, `calls [TOOL]` | Start over; read the state and call log |
+
+### What the fake can't show
+
+- Rendering: the headset view, desktop capture content, live video, SteamVR,
+  gamescope and panels. The capture stub returns a placeholder PNG.
+- Proton and FEX: whether a Windows or x86-64 program actually runs.
+- Android: there's no Android in the Lepton stand-in, so no ADB, display
+  settings, probes or app crashes.
+- The real Steam client's UI and anything it does that isn't modelled, and
+  mDNS discovery.
+- `sudo` and the power buttons, Tailscale, and the Windows and macOS sides of
+  the app (the host container is Linux, so the `rsync` paths are tested and the
+  `scp` fallback isn't).
+
+## Headset smoke test
+
+```sh
+scripts/frame-smoke.sh           # needs `ssh frame` to work without a password
+scripts/frame-smoke.sh --pair    # also pairs a throwaway key: approve it in the headset
+```
+
+It checks `properties.json` and the status, then installs, launches and
+removes three tiny titles built from bytes by `tests/smoke/tiny_programs.py`
+(an ARM64 and an x86-64 static Linux program that sleep for ten seconds, and
+an x86-64 `.exe` that exits at once). A launch passes only with fresh evidence:
+the ARM64 program running, the `.exe` started (its process or Steam's log),
+and the x86-64 program running or Steam logging that its runtime isn't
+installed, which is what the Frame does today. Steam's log lines about each
+title are kept.
+
+Everything it installs is removed again, also after a failure: the titles and
+their Steam shortcuts, a paired key, and `~/devkit-utils` if it wasn't there
+before (if it was, it stays, synced to this checkout as Frame Control always
+does). A cleanup that fails counts as a failed step. Results go to
+`tests/smoke/results/<time>-<BUILD_ID>.json` (not committed) with a summary on
+screen; it exits 0 when every step passed, 1 if one failed, 2 if the headset
+isn't reachable.
+
+`--pair` asks the devkit service to pair a new RSA key, which needs someone
+in the headset to open **Settings → Developer → Pair new host** and approve
+it; the key is checked and then taken out of `authorized_keys` again.
+
+## When the device disagrees with the fake
+
+The fake is only as good as what's been seen on a headset. When the smoke
+test (or anyone) finds the Frame doing something else:
+
+1. Record what the device did, with the date and BUILD_ID, in the doc that
+   covers it (`docs/sideloading.md`, `docs/ssh.md` and so on).
+2. Change the fake to match, with a comment citing that observation. The
+   behaviours are in `tests/fakeframe/rootfs/usr/local/lib/fakeframe/`
+   (`fakesteam.py` for Steam, `cef_shim.js` for DevTools, `init.py` for the
+   switches, the stubs in `rootfs/usr/local/bin`).
+3. Run `scripts/e2e.sh`. If the app is wrong, the tests now fail the way the
+   device did; fix the app and add a unit test.
+
+For example, on 2026-09-27 the smoke test found that Steam's `create-shortcut`
+refuses ids with a hyphen (`missing/invalid arguments`), which the fake had
+accepted. The fake now refuses them the same way, and Frame Control makes ids
+Steam accepts.

+# Website
+
+The Frame Control website, <https://frame-control.pages.dev>, on Cloudflare Pages.
+
+- `public/`: static pages. `/` is the landing page, `/feedback/` the feedback form, `/privacy/` the privacy note.
+- `functions/api/feedback.js`: `POST /api/feedback`, which turns the form into a GitHub issue labelled `feedback`.
+- `lib/feedback.js`: validation and issue formatting, tested by `test/feedback.test.mjs`.
+- `public/js/site.js`: settings, including the Ko-fi page name for the donate buttons.
+
+## Feedback → GitHub issues
+
+The function needs a `GITHUB_TOKEN` secret: a fine-grained token with **Issues: read and write** on
+`saphid/frame-control` only. Issues are opened as the token's owner, so they pass the contributor gate
+(`.github/workflows/issue-gate.yml`) and stay open. Without the token the form answers 503 and offers a
+prefilled GitHub issue instead.
+
+```sh
+cd site
+npx wrangler pages secret put GITHUB_TOKEN --project-name frame-control
+```
+
+Spam protection: a hidden honeypot field, a 3-second minimum fill time, 5 submissions per hour per IP
+(a salted hash, kept in the `FEEDBACK_RL` KV namespace for about an hour), and 100 a day in total.
+User text has `@mentions` and `#123` references broken so nobody gets pinged.
+
+## Run and deploy
+
+```sh
+cd site
+node --test test/*.test.mjs
+npx wrangler pages dev --port 8788           # local; put GITHUB_TOKEN/GITHUB_REPO in .dev.vars to test issues
+npx wrangler pages deploy --branch main      # production
+```
+
+Point `GITHUB_REPO` in `.dev.vars` at a scratch repo when testing locally so test issues don't land on the real tracker.
