+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.

+## Community reports

+It skips invalid reports and anything over 30 per reporter per day. Each run
+re-reads the last 30 days, because an offline copy sends its reports late,

+remembers which reports it has handled and each reporter's daily count, so
+nothing is added twice and the cap holds across runs.
+
+It needs:

+- the PostHog project id: `"project"` in `ui/telemetry.json`
+- a personal API key with `query:read`: `POSTHOG_PERSONAL_API_KEY`, or in the
+  Keychain (service `frame-control-posthog`, account `personal-api-key`)

+# Frame Control for AI agents
+
+**Documented interface:** Frame Control's own stdlib Python MCP adapter wraps
+its loopback HTTP API. No API key, hosted service, model SDK or third-party
+helper app is needed. The assistant is our HTML/Python implementation hosted
+in the platform Chromium browser. Its optional LLM endpoint is user configuration.
+Installing other apps is an optional management action, never a prerequisite.
+
+## Connect an MCP client
+
+The default MCP command starts a private HTTP backend on a free loopback port,
+with a fresh local access key. It stops that backend when the MCP client closes
+stdin or sends SIGTERM. It uses its own SSH control socket, so closing it does
+not close the desktop app's connection. No manually started server is needed.
+
+Add this stdio server to your MCP client (use absolute paths):
+
+```json
+{
+  "mcpServers": {
+    "frame-control": {
+      "command": "python3",
+      "args": ["/absolute/path/frame-control/ui/frame_mcp.py"]
+    }
+  }
+}
+```
+
+For Codex, the equivalent registration is:
+
+```sh
+codex mcp add frame-control -- python3 /absolute/path/frame-control/ui/frame_mcp.py
+```
+
+New agent sessions load the entry. An already running session may need its MCP
+connections reloaded; registration does not retroactively add tools to its
+initial tool inventory. Keep the checkout at that path while it is registered.
+Use `codex mcp remove frame-control` to remove only this registration.
+
+To reuse a running server instead, pass `--url http://127.0.0.1:47810`.
+The desktop app uses a random port; use that port with `--url`, or run the
+checkout server above. If the HTTP server uses `FRAME_UI_KEY`, pass the same
+value in the MCP process environment. This is local access control, not an LLM
+API key. The adapter only accepts loopback HTTP servers, refuses redirects and
+ignores environment proxies. Stdout contains newline-delimited JSON-RPC only.
+It supports MCP initialization, ping, tool listing and tool calls; no sampling,
+resources, prompts or streaming transport.
+
+| Tool | Arguments | Effect |
+|---|---|---|
+| `computer_state` | none | Read-only gamescope window IDs/focus and bounded AT-SPI tree; reports incomplete observations |
+| `status` | none | Battery, services, installed games and Flatpaks |
+| `screenshot` | `view`: `headset` (default) or `desktop` | Returns PNG image content to the MCP client |
+| `job` | `id` | Background install status; poll until `done`, inspect `error` |
+| `launch` | `appid` | Launch an installed Steam app |
+| `install` / `uninstall` | `id` | Install from Flathub / remove a user Flatpak |
+| `send_text` | `text` | Frame desktop clipboard; desktop must be open |
+| `send_file` | `path` | File on the HTTP server computer, up to 16 MiB, copied to Frame `~/Downloads` |
+| `panel` | `id` | Launch an installed Flatpak as a panel using the existing launcher |
+| `power` | `action`: `suspend`, `reboot`, `poweroff` | Open a terminal for the user to enter the sudo password |
+| `keep_awake` | `action`: `on`, `off`, `status` | Optional keep-awake script interface |
+
+Only install free software with its developer's consent. There is no purchase,
+entitlement bypass or arbitrary shell tool. `install` returns a background job
+ID; it does not claim the installation has finished. APK and sideloaded title
+installs remain in the main UI for now.
+
+### Approval is a separate human action
+
+Every mutation first returns an `approvalUrl`, exact action and `confirmation`
+token. Ask the user to open that URL and choose **Approve this action** or
+**Reject**. Then repeat the same tool and arguments with the token in
+`confirmation`. The server refuses execution before approval, changed arguments,
+expired tokens and reuse. A file approval binds the content hash as well as the
+path. Approvals last five minutes and disappear when the HTTP server restarts.
+A failed execution also consumes the approval; review a fresh request to retry.
+The panel does not execute an action merely because it was approved.
+
+MCP has no approval tool. This is protection against accidental model tool
+calls, not a sandbox against a client with independent shell/HTTP access to your
+computer. Grant the MCP client only the access you intend. Status, captures and computer-state observations
+are returned directly to that client, which may forward them to its configured
+model. The assistant's separate opt-in does not govern an external MCP client.
+
+Power still requires the existing password prompt in a local terminal. MCP
+never receives passwords. Power via `FRAME_LOCAL=1` is unsupported: use the main
+UI. The panel launcher and keep-awake adapter require zsh on the computer.
+
+[PR #16](https://github.com/saphid/frame-control/pull/16) owns
+`scripts/keep-awake.sh on|off|status`. This branch does not copy or change it.
+Until that script is present, the tool reports it unavailable. Keep-awake is
+never automatic: `on` changes the shared idle timers; explicitly approve `off`
+to restore them after work. It is not a per-agent lease; coordinate with other
+users. No changes are made to the analytics/update interfaces in
+[PR #17](https://github.com/saphid/frame-control/pull/17). Prompts, keys, model
+replies, screenshots and approval payloads are not sent to analytics.
+
+## Assistant panel
+
+Open **Tools → Open assistant**, or `http://127.0.0.1:47810/assistant`.
+To put the same page in the headset, with the HTTP server still running:
+
+```sh
+python3 scripts/assistant-on-frame.py --port 47810
+```
+
+This starts an SSH reverse forward bound to Frame loopback (port 47812 by
+default), then a dedicated Chromium profile tagged as a SteamVR panel. Keep the
+command running. Ctrl-C closes this browser profile and the tunnel; it leaves
+other Chromium windows and the existing HTTP server alone. A failed cleanup
+prints the temporary profile path so it can be removed when the Frame returns.
+Use `--frame-port` if the default is busy. Chromium must already be available as
+`org.chromium.Chromium`; the launcher never installs anything automatically.
+Place the panel with SteamVR's normal docking controls.
+
+Enter your full **chat-completions endpoint**, model name and optional key.
+An OpenAI-compatible local server works without a key; no OpenAI account is
+required. HTTP is allowed only on loopback; other endpoints require HTTPS.
+Loopback refers to the computer running the HTTP server, even in the headset.
+Endpoints with embedded credentials, query strings or redirects are refused.
+
+Check the message consent box and press **Send message**. Screenshot context is
+a separate unchecked box and sends one fresh capture with that request. Both
+boxes reset after sending, and changing endpoint/model revokes consent. Nothing
+is sent when opening the page or entering configuration. There is no model
+list fetch, saved history, automatic screenshot capture or assistant telemetry.
+Each send is independent: previous messages and replies are not included.
+
+Configuration, credentials and chat remain in page memory; close/reload the page
+or choose **Clear everything** to clear them. A request already sent cannot be
+recalled. Only the chosen endpoint gets the request; proxy environment variables
+and redirects are disabled. Its privacy and retention policy still applies.
+Replies are plain text and cannot call tools or operate the Frame. A model must
+support image inputs to accept screenshot context.
+
+## Evidence and limits
+
+**Verified 2026-09-28, SteamOS 0.4.1, BUILD_ID 20260925.6191901:** loopback HTTP
+status through an SSH reverse tunnel; platform Chromium created a separate
+SteamVR panel (confirmed in `GAMESCOPE_FOCUSABLE_APPS`); headset capture returned
+a PNG. These checks preceded the UI implementation. No power or global settings
+were changed.
+
+**Inferred:** visual comfort and controller keyboard usability while wearing
+the headset; panel creation in gamescope alone does not establish these.
+Windows/Linux launcher support, live third-party model endpoints, installs,
+uninstalls, power and keep-awake changes are not covered by that feasibility
+check. See the PR for the final unit and end-to-end results.
+
+**Verified end to end on the same Frame/build (2026-09-28):** a stdio MCP client
+initialized, read status, retrieved a headset PNG, and transferred a test file
+only after approval through the Chromium page. Remote file bytes matched;
+reusing the confirmation was rejected. The actual headset Chromium page sent
+text and then separately opted-in image context to a local test endpoint and
+displayed its replies. Without consent there were zero endpoint requests.
+The test endpoint returned canned replies: model inference and a live external
+provider remain **unverified**. The launcher’s Ctrl-C cleanup was checked;
+profiles, SSH tunnels and the test file were removed. No installs, removals,
+launches of user games, power operations or keep-awake changes were performed.
+
+**Verified locally:** unit coverage includes the stdio subprocess, approval
+binding/expiry/replay/concurrency, file-change rejection, and a real local HTTP
+endpoint for opt-in, text/image payloads and redirect refusal. Fake-Frame
+regressions are in `tests/e2e/test_agents.py`; local Docker execution was blocked
+because the Docker daemon was unavailable. The ARM64 fake-Frame CI job passed
+on this branch (run 36421345682).
+
+**Verified on the same Frame/build:** both Ctrl-C and SIGTERM close the dedicated
+browser profile and SSH tunnel and remove the profile and panel log.
+
+![Assistant in Frame Chromium, after an opted-in request to the local test endpoint](img/assistant-panel.png)
+
+## Computer-use coverage
+
+MCP is the tool transport, not a limit on what an agent can do. A screenshot,
+accessibility snapshot, click or keystroke can all be MCP tools when we have a
+reliable underlying implementation. See [the investigation](computer-use.md)
+for the verified boundaries. `computer_state` adds observation, not an input
+channel: it cannot click an approval button or send keyboard/mouse events.
+
+**Verified 2026-09-29, SteamOS 0.4.1, BUILD_ID 20260925.6191901:** the command saved
+by `codex mcp add` launched without a prestarted server, negotiated MCP, listed
+12 tools, read live Frame status and returned X11 window state plus AT-SPI
+observations. It exited 0 at EOF. Steam's accessibility tree had inaccessible
+children, reported as `incomplete: true`; this is not a complete actionable UI.

+## 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 |

+## 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

+
+## 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.

+Choose **Install** to download a listed version, verify its SHA-256 against

+
+The search links open APKMirror, APKPure, Uptodown, F-Droid and GitHub. Pick a
+version whose minimum is Android 11 or lower and that has an arm64-v8a build
+(or no native code). Frame Control does not fetch APKs from those search sites.

+# Computer use through Frame Control MCP
+
+The MCP transport can carry semantic actions or visual computer-use actions.
+The limits are the Frame's underlying interfaces, permissions and whether an
+action can be targeted and verified. A stereoscopic headset screenshot alone
+is not a reliable coordinate system for clicking a particular app window.
+
+## What exists, and the right route
+
+| Surface | Evidence and route | Remaining work or boundary |
+|---|---|---|
+| Frame management | **Verified:** existing SSH/HTTP operations for status, capture and file transfer work through MCP. Typed install/launch/power tools wrap the existing API. | Extend typed operations before adding generic mouse automation. Preserve explicit approval for consequential changes. |
+| App/window observation | **Verified 2026-09-29:** `computer_state` reads gamescope X11 window/app/process triples, focused app and the installed AT-SPI library. | Bounded to 96 accessible nodes and six levels. Trees may be truncated, stale, hidden or incomplete. Snapshot paths and XIDs are observations, never durable action permissions. |
+| Chromium page content | **Verified previously:** the assistant rendered and could be exercised through CDP in an isolated Frame Chromium profile. | A shipped click/type surface needs exact owned browser/target binding, fresh element references, lifecycle cleanup, consent and post-action readback. Do not expose unrestricted JavaScript or attach to arbitrary existing profiles automatically. |
+| Steam UI | **Verified 2026-09-29:** the AT-SPI service listed the Steam client's Chromium process and frame nodes, but child traversal was incomplete. Existing `frame_steam.py` uses Steam's loopback CDP endpoint for specific operations. | Prefer those narrow Steam interfaces. Presence of AT-SPI does not prove controls are actionable, and generic pointer injection is not proved for VR menus. |
+| Other Linux apps | **Verified 2026-09-29:** Frame ships libX11, libXtst and libatspi; `/dev/uinput` is writable by the current user. | Library presence and access permissions do not prove that a game accepts input. Global virtual input can affect whichever app has focus. Do not ship a blind keyboard/mouse tool on this evidence alone. |
+| Panel focus and layouts | **Documented in [#41](https://github.com/saphid/frame-control/pull/41):** `POST /api/panels` accepts `list`, `focus` and `open`. Focus was verified there. | Reuse that owned interface after integration. Its tested gamescope-owned overlay transform setters return `PermissionDenied`; no reliable saved spatial-layout interface was established. Do not duplicate its implementation here. |
+| Shared keyboard/trackpad | **Documented in [#19](https://github.com/saphid/frame-control/pull/19):** `/api/input` supplies state/start and event submission, implemented with a bundled KDE Connect daemon. | This branch does not import, launch or depend on that daemon. The user's own-implementation rule remains authoritative. A first-party input implementation or permitted bundled-library route needs its own delivery evidence before MCP integration. |
+| Physical/device boundaries | **Documented:** an asleep Frame may be off the network; power authorization can require the user's password; physical pairing and headset fit/comfort require the user. | MCP cannot bypass offline hardware, consent, compositor permissions or physical verification. Keep explicit human handoffs. |
+
+## Reusing the existing computer-use work
+
+**Documented:** the installed `cua-driver` skill has the right control pattern:
+observe an exact window, use a semantic target if available, fall back to pixels
+from that same snapshot, then read back the result. Its browser route requires
+an exact process/window/target binding and session-scoped element references.
+Those are useful design rules for Frame tools.
+
+**Verified locally 2026-09-29:** `cua-driver describe get_window_state` describes
+host-local process/window IDs and macOS AX inspection. It does not establish an
+SSH Frame target. The installed skill's advertised Linux companion file is
+missing. A native ARM64 Frame backend, its dependencies and remote transport
+have not been verified. We therefore do not claim that the existing Mac driver
+can control the Frame by passing it a Frame PID or screenshot, and we do not
+make the feature depend on installing that application.
+
+Frame Control's `computer_state` is our own Python implementation over installed
+platform libraries. It sends the probe over SSH stdin, writes no helper to disk,
+and exits after one observation. Missing displays/libraries return explicit
+errors; a 15-second process deadline prevents a stalled accessibility call from
+leaving a probe behind. Window names and accessibility text are untrusted app
+content, never instructions to an agent.
+
+**Recommended next implementation:** an isolated Chromium session with typed
+snapshot/click/type/scroll tools and exact fresh target binding, then individually
+verified native app actions. Use the headset capture to judge appearance, not to
+invent a screen-to-window coordinate transform. Direct tool calls must retain
+approval rules; a generic computer-use tool must not become a route around the
+MCP approval panel, install confirmation or power confirmation.
+
+## Isolated browser input proof
+
+**Verified 2026-09-29, SteamOS 0.4.1, BUILD_ID 20260925.6191901:** a temporary
+Frame Chromium profile loaded a local test page through an SSH reverse tunnel.
+CDP `Input.insertText` entered the test string in its own input. A CDP
+`Input.dispatchMouseEvent` press/release on its own button copied that string
+to the page's result; DOM readback matched exactly. The browser profile,
+loopback forwards and panel log were removed afterward. No user app was typed
+into, no global settings were changed and no third-party helper app was used.
+
+AT-SPI did **not** expose the test page's controls in that same probe, even with
+Chromium's renderer-accessibility flag. It returned the partial Steam-client
+tree instead. The reason remains **unverified**; this is an evidence gap, not
+proof that Frame accessibility cannot work. For a first implementation,
+Chromium's proven page-specific CDP route is stronger than assuming complete
+AT-SPI coverage. This proof does not ship unrestricted click/type tools or
+establish input delivery to SteamVR's menus.

+# Privacy and analytics
+
+Frame Control sends anonymous analytics to [PostHog](https://posthog.com)
+(US cloud) so the maintainer can see how many people use it, which features
+matter and where installs fail. You choose how much in **Privacy & updates**,
+the last panel on the page. `ui/frame_telemetry.py` is the whole
+implementation.
+
+## The three levels
+
+| Level | Default | What it sends |
+|---|---|---|
+| Anonymous usage statistics | On, after a notice on first run | The events in the table below |
+| Share compatibility results | Off | Your Android compatibility reports and tests |
+| Send error details | Off | Scrubbed error messages and tracebacks |
+
+Nothing is sent until the first-run notice has been shown. The notice's
+**Share more to help fix problems** button turns on the second and third
+levels together. Either can be turned off later. Turning a level off
+deletes that level's events that haven't been sent yet.
+
+**Show what's been sent** in the panel lists the last 50 events that left your
+computer, exactly as they were sent.
+
+## Anonymous
+
+- Events carry a random id, made when Frame Control first runs and kept in
+  its data folder (`telemetry/settings.json`). It isn't derived from your
+  computer, account or network. To get a new one, delete that file.
+- Events are sent without person profiles (`$process_person_profile: false`)
+  and without location lookup (`$geoip_disable: true`). Each carries a
+  placeholder address (`$ip: 0.0.0.0`), so PostHog stores that instead of
+  yours.
+- Every event includes the app version, OS name (macOS, Windows or Linux),
+  CPU architecture and Python version.
+
+## Usage events
+
+| Event | When | Properties besides the common ones |
+|---|---|---|
+| `app_installed` | First run | |
+| `app_updated` | First run of a new version | `from_version` |
+| `app_opened` | At most once a day | |
+| `frame_connected` | The first time a SteamOS build is seen | `steamos_build`, `steamos_version` |
+| `tab_viewed` | The first click on each tab in a session | `tab` |
+| `install_finished` | Any install finishes, working or not | `kind` (apk, flatpak, steam, title, web), `ok`, `seconds`, `error_category`, `installer_code`, and see below |
+| `update_offered`, `update_started`, `update_failed` | The update banner | `to_version`, `error_category` |
+
+`install_finished` never includes a file name, path or error message. An
+error becomes one category from a fixed list (for example `apk_wrong_abi` or
+`frame_unreachable`), plus Android's own `INSTALL_FAILED_…` code when there
+is one. It names what was installed only when that's already public:
+
+- F-Droid catalogue apps: `package`. Never the version, since a local build can reuse a
+  catalogue app's package name
+- Flathub apps: `flatpak_id`
+- Steam games: `steam_appid`
+- A sideloaded title: only its runtime (Proton or Linux)
+
+Any other APK is sent as `catalog: false`, with no name.
+
+## Compatibility results (opt-in)
+
+Each report becomes a `compat_report` event with the fields the Report dialog
+shows: package, version, result or rating, your notes, how it was run, and the
+SteamOS and Lepton builds. Before sending:
+
+- the notes, app name and version are scrubbed like error messages (see
+  below)
+- the APK's source is kept only if it's `F-Droid` or the public host name of
+  a download link (`https://example.com/…`). File names, user names,
+  passwords, ports, paths, IP addresses and local host names are dropped
+
+When you turn this on, reports you made earlier on this computer are shared
+too.
+
+The maintainer's `python3 ui/frame_compat_db.py sync` copies these events
+into the compatibility database, marked `via=community…`. It takes at most
+30 per reporter per day.
+
+## Error details (opt-in)
+
+`$exception` events carry an error message, the Frame Control file, line and
+function it came from, and the request that failed (for example
+`POST /api/android install`). Before anything is sent, the message is
+scrubbed:
+
+- your home folder becomes `~`, and any user name becomes `<user>`
+- IP and MAC addresses, email addresses, `.local`, `.lan` and Tailscale host
+  names, Steam ids, SSH and PEM keys, API tokens and long hex strings are
+  replaced
+- URLs are cut down to their scheme and a public host name, or `<url>`. User
+  names, passwords, ports, paths and queries are dropped
+- `token=`, `key=`, `password=` and similar values are replaced
+
+The same error is sent at most once every 10 minutes.
+
+## Report a problem
+
+**Report a problem** is the warning-sign button in the header, also in the
+Privacy panel and under **Help → Report a Problem…**. It sends the report
+privately to Frame Control's PostHog project as a `problem_report` event, the
+same way as the analytics above, so only the maintainer can read it and
+nothing is published. It works whatever the analytics settings are, because
+the person sends it deliberately. The report has the kind, title and text you
+wrote, how to reach you if you gave it, a short reference shown after sending,
+and the diagnostics below. It has its own random id, so it isn't linked to
+your analytics events.
+
+With **Include diagnostics** ticked (the default), the report adds:
+
+- the app version and whether it's a built app
+- the OS, its release and CPU, and the Python version
+- the Frame's SteamOS build, if it has connected since the app started
+- which analytics levels are on
+
+**Also include recent activity and the server log** is off by default,
+because those lines can name files and apps. When ticked, it adds the newest
+Activity lines and server log lines, without the request lines.
+
+Everything is scrubbed like error details and limited to what fits in the
+report. Environment details are kept first, then the newest lines. **Show
+exactly what's included** shows the snapshot that will be sent, and later
+activity isn't added to it. If PostHog can't be reached, **Copy report** puts
+the whole report on the clipboard.
+
+The maintainer reads reports on the Frame Control dashboard in PostHog, or
+with `python3 ui/frame_report.py inbox [days]`, which uses the same personal
+API key as `frame_compat_db.py sync`.
+
+## Turning it all off
+
+Untick the boxes, or set `DO_NOT_TRACK=1` or `FRAME_CONTROL_TELEMETRY=0` in
+the environment that starts Frame Control. A copy run from a source checkout
+never sends anything unless `FRAME_CONTROL_TELEMETRY=1` is set.
+
+## Update checks
+
+The desktop app asks GitHub for the latest release shortly after starting,
+then every 6 hours: the latest release's `update.json` on GitHub, or
+`api.github.com/repos/saphid/frame-control/releases/latest` if that fails.
+Those requests carry no id. To stop it, set
+`FRAME_CONTROL_NO_UPDATE_CHECK=1`. See [releasing.md](releasing.md).

+# Releasing and updates
+
+Frame Control checks for updates itself. The desktop app offers a new version
+only once it's GitHub's **latest release**, and drafts and pre-releases never
+count. So a build reaches people only when you publish it, after testing it.
+
+## Steps
+
+1. Bump `version` in `app/package.json`, commit, and push a tag:
+
+   ```sh
+   git tag v0.4.0 && git push origin v0.4.0
+   ```
+
+   `.github/workflows/release.yml` builds macOS, Windows and Linux, and
+   attaches everything to a **draft** release for that tag. Nobody is
+   offered a draft.
+
+2. Download the draft's installers and test them. An installed copy of the
+   previous version won't offer the draft, so install it directly.
+
+3. Write the release notes on the draft. The update banner links to them.
+
+4. Publish:
+
+   ```sh
+   scripts/publish-release.sh v0.4.0
+   ```
+
+   The script checks that all eight installers are attached, each with the
+   SHA-256 digest GitHub records. It attaches `update.json` (the version, the
+   notes and each installer's digest), then publishes the release and marks it
+   latest. From then on, running copies see the update. They check about 8
+   seconds after starting, then every 6 hours, and anyone can use **Check for
+   Updates…** (the app menu on macOS, the Help menu elsewhere).
+
+To pull a bad release, mark the previous one as latest
+(`gh release edit v0.3.9 --latest`) or turn the bad one back into a draft.
+Copies that already updated stay on it. Nothing downgrades them.
+
+## How a copy updates itself
+
+`app/updater.js` reads `update.json` from
+`github.com/saphid/frame-control/releases/latest/download/`. It falls back to the
+REST API only when a release has no manifest, because the API allows just 60
+unauthenticated requests an hour per IP address, shared by a whole household.
+Then it downloads the installer for its platform and checks it
+against the SHA-256 digest GitHub publishes for the asset. It refuses if the
+digest is missing or doesn't match. Then:
+
+| Installed from | Update |
+|---|---|
+| macOS `.dmg`, app in a writable folder such as Applications | The `.zip` is unpacked next to the app and its version checked. After the app quits, a small script swaps the new app in, putting the old one back if that fails, and reopens it. Updates don't get the download quarantine, so there's no `xattr` step. |
+| Windows installer | The new `Setup` runs silently over the install (`/S --force-run`) and reopens the app. |
+| Linux AppImage | The new AppImage replaces the old file and is started. |
+| macOS app still on the disk image or translocated, Windows `.zip`, Linux `.deb` | The banner opens the release page instead. |
+
+Version 0.3.1 and earlier have no updater, so people on them have to download
+the new version once by hand.

+**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

+```
-- **Clipboard from the Mac**: `scripts/paste-to-frame.sh` (see
+
-  [file-transfer.md](file-transfer.md#clipboard)).
+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

-It runs natively, not as a Flatpak. `launch` opens it as its own panel on
-gamescope's X display, the same way as [`panel-on-frame.sh`](../scripts/panel-on-frame.sh) ([panels.md](panels.md)), so
-the Plasma desktop doesn't need to be open. It uses its own profile
-(`~/.config/chromium-xr`) and DevTools on loopback port 9223, so it doesn't
-collide with the Flatpak's 9222. When a page enters VR, Chrome asks
-**Allow VR?** in the browser panel; choose *Allow this time* or *Allow while
-visiting the site*.
-
-Both ways of starting it run
-[`frame/chromium-xr/launch.sh`](../frame/chromium-xr/launch.sh), copied to
-`~/Applications/ChromiumXR/launch.sh` on the Frame, which holds Chrome's flags.
-It sits outside `~/chromium-xr` so `install` doesn't delete it.
-
-**From the Steam library (verified 2026-09-26).** `steam` adds a non-Steam
-shortcut called "Chromium XR" (with the Flathub Chromium icon, if that's
-installed) through the Steam client's DevTools port, the same way as T3 Code
-([apks.md](apks.md)), without restarting Steam. It saves the app id in
-`~/Applications/ChromiumXR/shortcut-appid`, so rerunning it, even after you
-rename the shortcut in the library, doesn't add a second one. On this Frame
-the shortcut app id is 2240749789. Launching it from the library gives
-Chromium its own panel, `valve.steam.desktopgame.2240749789`, like any other
-app. A Steam launch doesn't open a DevTools port, so `check` needs `launch`.
-Chromium runs one browser per profile: while the Steam-launched one is open,
-`launch` opens its URL in that window, without DevTools, then prints
-`failed: ... exited` because no new window appeared. Close it first.
-
-**Seccomp is off.** The wrapper passes `--disable-seccomp-filter-sandbox`. With
-the XR seccomp policy on, SteamVR's client reads `/proc/self/status` through
-Chrome's file broker and gets the broker's pid. SteamVR then binds the app to
-the wrong process ("Unable to init path manager: VRInitError_Init_Internal")
-and `xrCreateInstance` fails. The broker can't answer `/proc/self` for another
-process, so fixing this needs a change in Chromium's broker client or in the
-CL. The namespace sandbox stays on, but seccomp is off for every process, so
-use this profile for VR sites rather than everyday browsing. DevTools on
-port 9223 has no authentication. It listens on loopback, but with the
-userspace Tailscale from [tailscale.md](tailscale.md) running, loopback ports
-are reachable from your tailnet. Close the browser when you're done.

+# 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.
