1. Check installed version          → registry read above
2. Decide:
     no install         → install bundled AD
     older than bundled → install bundled AD (upgrade)
     same or newer      → skip install entirely
3. Run installer (silent + /NOLAUNCH)   → tail log, surface to UI
4. Write embedded marker file       → %LOCALAPPDATA%\Adom Desktop\embedded.json
5. Delete AD's user-facing shortcuts → Start Menu, Desktop, Startup folder
                                       (so user can't double-launch standalone)
6. Spawn AD with embedded flags     → adom-desktop.exe --embedded
                                          --start-hidden

name: adom-desktop-installer
description: How to invoke the Adom Desktop NSIS installer from a parent installer (especially Hydrogen Desktop's setup steps) — silent install, /NOLAUNCH switch for HD-managed bundling, live progress via the structured log file at %TEMP%\adom-desktop-install.log. Use when bundling AD inside another Windows installer, writing an install supervisor / setup-step UI, detecting AD's installed version, or upgrading an existing AD install programmatically.

# Adom Desktop installer integration

Adom Desktop (AD) ships as a single NSIS installer:

```
Adom Desktop_<version>_x64-setup.exe   (~4.8 MB on v1.8.45)
```

It installs to `%LOCALAPPDATA%\Adom Desktop\` — no UAC prompt, no admin needed. Tauri-2 bundled NSIS with our customisations in `src-tauri/installer-hooks.nsh`.

## Command-line surface

| Flag | Meaning |
|---|---|
| (none) | Installs silently, auto-launches `adom-desktop.exe` after install |
| `/S` | Standard NSIS silent flag — same behavior since the top-level `SilentInstall silent` directive already suppresses UI |
| `/NOLAUNCH` | **v1.8.45+** — install silently, do NOT auto-launch after install. Caller is responsible for spawning AD with the desired flags |
| `/D=<path>` | Install destination override. Default is `$LOCALAPPDATA\Adom Desktop`. Rarely needed |
| `<uninstall.exe> /S` | Silent uninstall. The uninstaller lives at `%LOCALAPPDATA%\Adom Desktop\uninstall.exe` |

**UI behavior**: zero UI in all cases. `SilentInstall silent` is set at the top of the NSIS script, so even `setup.exe` invoked from Explorer runs without a window. No Welcome page, no progress bar, no Finish page.

**Auto-launch**: by default the installer calls `ExecShell "" "$INSTDIR\adom-desktop.exe"` at the end of POSTINSTALL. Pass `/NOLAUNCH` to suppress this. Used by HD when bundling AD because HD wants to spawn AD with `--embedded --start-hidden --relay-url ... --session-token ...` itself, not let AD launch standalone first and get respawned via single-instance.

## Live progress log

The installer writes structured progress to `%TEMP%\adom-desktop-install.log` (Windows expands `%TEMP%` to the user's temp dir, typically `C:\Users\<name>\AppData\Local\Temp`). Each line is `[STAGE] message\r\n`:

```
[START] adom-desktop installer 1.8.45 starting
[PREINSTALL] Cleaning legacy desktop shortcuts
[PREINSTALL] Done. Tauri will now copy bundle files.
[POSTINSTALL] Bundle files copied. Cleaning Tauri's auto-created desktop shortcut.
[POSTINSTALL] /NOLAUNCH passed — skipping auto-launch (caller will spawn)
[DONE] adom-desktop installer complete (no-launch mode)
```

**`[START]`** opens with a truncated write (fresh log per install). **`[DONE]`** is always the final line — readers tailing the file can use that as the completion sentinel without needing to wait for the process exit.

Stage tags currently emitted:
- `[START]` — once, at the top
- `[PREINSTALL]` — Tauri's beforeBuildCommand hook ran, files about to be copied
- `[POSTINSTALL]` — files copied; Tauri's standard shortcuts created and our hook is cleaning the unwanted ones
- `[DONE]` — final line, installer about to exit

The uninstaller writes the same log with `[PREUNINSTALL]` / `[POSTUNINSTALL]` stages.

## Recipe: HD's setup-step UI tails the log

Spawn the installer with `/NOLAUNCH`, poll the log file on a 200 ms timer, surface each new line to HD's UI. When `[DONE]` shows up OR the process exits, the install is complete.

### Rust (HD's installer driver)

```rust
use std::{env, fs, path::PathBuf, process::Command, time::Duration};
use std::os::windows::process::CommandExt;
use tokio::time::sleep;

const CREATE_NO_WINDOW: u32 = 0x08000000;

async fn install_adom_desktop<F: FnMut(String)>(
    installer_path: &str,
    mut on_line: F,
) -> Result<(), String> {
    let log_path: PathBuf = [&env::var("TEMP").map_err(|e| e.to_string())?, "adom-desktop-install.log"]
        .iter()
        .collect();
    // Pre-clear so we don't read stale lines from a previous install.
    let _ = fs::remove_file(&log_path);

    let mut child = Command::new(installer_path)
        .args(["/S", "/NOLAUNCH"])
        .creation_flags(CREATE_NO_WINDOW)
        .spawn()
        .map_err(|e| format!("spawn installer: {e}"))?;

    let mut last_pos = 0usize;
    loop {
        // Tail any new content
        if let Ok(content) = fs::read_to_string(&log_path) {
            if content.len() > last_pos {
                let slice = &content[last_pos..];
                if let Some(last_nl) = slice.rfind('\n') {
                    let consumed = &slice[..=last_nl];
                    for line in consumed.lines() {
                        on_line(line.to_string());
                        if line.starts_with("[DONE]") {
                            // Don't return yet — wait for process exit
                            // so we surface the actual exit code, but
                            // we know progress streaming is finished.
                        }
                    }
                    last_pos += consumed.len();
                }
            }
        }
        // Check if installer has exited
        if let Some(status) = child.try_wait().map_err(|e| e.to_string())? {
            return if status.success() {
                Ok(())
            } else {
                Err(format!("installer exited with {}", status))
            };
        }
        sleep(Duration::from_millis(200)).await;
    }
}

// Caller:
// install_adom_desktop(r"C:\path\to\Adom Desktop_1.8.45_x64-setup.exe", |line| {
//     hd_setup_step.append_live_output(&line);
// }).await?;
```

### Bash (debugging / scripting)

```bash
# Pre-clear stale log
rm -f "$TEMP/adom-desktop-install.log" 2>/dev/null

# Spawn installer in background, tail the log
"./Adom Desktop_1.8.45_x64-setup.exe" /S /NOLAUNCH &
INSTALLER_PID=$!

# Tail until process exits OR [DONE] appears
while kill -0 $INSTALLER_PID 2>/dev/null; do
  [ -f "$TEMP/adom-desktop-install.log" ] && tail -F "$TEMP/adom-desktop-install.log" &
  sleep 0.2
done
wait
echo "Installer exited"
```

## Recipe: detect if AD is already installed (and at what version)

The signed NSIS installer (`installMode: "currentUser"`) writes AD's uninstall info to `HKCU` — no admin needed. **⚠ The key name is the product name `Adom Desktop` (WITH a space), NOT `AdomDesktop`** (verified live 2026-07-03). Two history notes so you don't chase the wrong key:
- The NSIS uninstall key = the product name → `…\Uninstall\Adom Desktop` (space).
- AD's OWN launch-time code used to ALSO write an `AdomDesktop` (no-space) key to **HKLM** — that write was **DELETED in v1.9.68** (the no-UAC fix). So `AdomDesktop` no longer exists anywhere; read `Adom Desktop`.

```
HKCU\Software\Microsoft\Windows\CurrentVersion\Uninstall\Adom Desktop
  DisplayName       = "Adom Desktop"
  DisplayVersion    = "1.9.74"
  InstallLocation   = "C:\Users\<name>\AppData\Local\Adom Desktop"
  UninstallString   = "C:\Users\<name>\AppData\Local\Adom Desktop\uninstall.exe"
  Publisher         = "Adom Industries, Inc."
```

```rust
use winreg::enums::HKEY_CURRENT_USER;
use winreg::RegKey;

fn adom_desktop_installed_version() -> Option<String> {
    let hkcu = RegKey::predef(HKEY_CURRENT_USER);
    // NOTE the SPACE — the NSIS uninstall key is the product name "Adom Desktop".
    let key = hkcu
        .open_subkey(r"Software\Microsoft\Windows\CurrentVersion\Uninstall\Adom Desktop")
        .ok()?;
    key.get_value("DisplayVersion").ok()
}
```

Compare with `semver::Version::parse` to decide whether to skip / upgrade / leave-alone.

## Recipe: HD's setup-step ladder for embedding AD

The full pattern HD's setup-step UI runs when embedding AD:

```
1. Check installed version          → registry read above
2. Decide:
     no install         → install bundled AD
     older than bundled → install bundled AD (upgrade)
     same or newer      → skip install entirely
3. Run installer (silent + /NOLAUNCH)   → tail log, surface to UI
4. Write embedded marker file       → %LOCALAPPDATA%\Adom Desktop\embedded.json
5. Delete AD's user-facing shortcuts → Start Menu, Desktop, Startup folder
                                       (so user can't double-launch standalone)
6. Spawn AD with embedded flags     → adom-desktop.exe --embedded
                                          --start-hidden
                                          --relay-url ws://127.0.0.1:8765
                                          --relay-name hydrogen-desktop
                                          --session-token <hd's token>
7. Poll AD's direct API for liveness → GET http://127.0.0.1:47200/health
```

Steps 4 and 5 are also covered by AD's installer if you pass `--embedded` at AD's first launch (the embedded-mode detection writes the marker and AD's autostart-upgrade routine handles its own shortcuts). Doing them in HD's installer is belt-and-suspenders.

## Bundle-resource pattern

HD's `tauri.conf.json` should include the AD installer as a bundle resource so it ships inside HD's NSIS installer:

```json
"bundle": {
  "resources": {
    "resources/Adom Desktop_1.8.45_x64-setup.exe": "resources/"
  }
}
```

At runtime HD finds it under its install dir at `$INSTDIR\resources\Adom Desktop_<ver>_x64-setup.exe` — pass that path to the install function above.

## Versioning + upgrade strategy

| Scenario | What HD's installer should do |
|---|---|
| No AD installed | Install bundled version |
| AD older than bundled | Install bundled version (upgrade) |
| AD same as bundled | Skip install step; still spawn with embedded flags |
| AD newer than bundled | Skip install step; spawn with embedded flags. Don't downgrade — embedded mode works for any AD ≥ v1.8.42 |

The bundled AD installer is the minimum supported version for the HD release. HD can spawn newer ADs without modification.

## Exit codes

NSIS returns:
- `0` — install succeeded
- `2` — user cancelled (won't happen with `SilentInstall silent` since there's no UI to cancel)
- Other — install error (rare with our hooks; typical cause is disk full or `%LOCALAPPDATA%` not writable)

Treat anything non-zero as a hard failure and surface the log file's last 20 lines to the user.

## Where the installer lives

**v1.8.115+** — the end-user binary home is the **V2 wiki blob store** (the
GitHub repo is private; GH release URLs 404 for anonymous downloads). Two
discovery surfaces, both anonymous:

**Preferred for parent installers (HD setup): the packages API.** Resolve
the latest registered version and its assets in one or two GETs — note
`?org=adom` is REQUIRED (the slug exists in multiple orgs; bare URLs 400):

```
https://wiki.adom.inc/api/v1/packages/adom-desktop/dist-tags?org=adom
  → {"dist_tags":{"latest":"X.Y.Z"}}
https://wiki.adom.inc/api/v1/packages/adom-desktop/manifest?org=adom
  → { version, ..., assets: { "windows-x64": { filename, url, sha256, size } } }
```

The `assets` map is server-derived from the page's blobs (sha256 computed
from the actual bytes — integrity-checkable). `assets[...].url` is
server-relative (`/blob/app/adom-desktop/<file>`); prefix the git-wiki host.

**Fallback / updater path: version.json**, V2-first with V1 fallback:

```
https://wiki.adom.inc/api/v1/pages/adom-desktop/files/version.json
https://wiki.adom.inc/api/v1/pages/adom-desktop/files/version.json
```

The V2 manifest's `windows.installer_url` / `cli.<plat>.binary_url` point at
the V2 files endpoint; V1's point at V1 static copies. **Follow the
manifest's URLs — do NOT construct binary URLs by hand.**

Network quirk: HEAD on V2 blob/file URLs may return 404 while GET works
(git-wiki #40 — fix in flight). Probe with a Range GET (`Range: bytes=0-0`,
expect 206), never bare HEAD. Asset filenames are dot-form everywhere
(`Adom.Desktop_<ver>_windows_x64-setup.exe`); V1 dot-normalized since v1.8.72.

The wiki page's `metadata.install.windows_installer` field points at the
canonical filename for the current published version. HD's release build
should fetch the latest via the V2-first pattern:

```bash
# Try V2 first, fall back to V1.
fetch_manifest() {
  curl -fL --max-time 15 \
    "https://wiki.adom.inc/api/v1/pages/adom-desktop/files/version.json" \
    2>/dev/null \
  || curl -fL --max-time 15 \
    "https://wiki.adom.inc/api/v1/pages/adom-desktop/files/version.json"
}

MANIFEST=$(fetch_manifest)
INSTALLER_URL=$(echo "$MANIFEST" | jq -r .windows.installer_url)
INSTALLER_SHA=$(echo "$MANIFEST" | jq -r .windows.installer_sha256)
# Each manifest carries a self-consistent installer_url that points at the
# SAME backend the manifest was served from — V2 manifest → V2 installer URL,
# V1 manifest → V1 installer URL. No URL mixing across backends.

curl -fL "$INSTALLER_URL" -o resources/ad-setup.exe

# Verify SHA256 before bundling — defends against partial fetches + tampering
DOWNLOAD_SHA=$(sha256sum resources/ad-setup.exe | awk '{print $1}')
[ "$DOWNLOAD_SHA" = "$INSTALLER_SHA" ] || { echo "SHA mismatch"; exit 1; }
```

The desktop AD's built-in auto-updater (`src-tauri/src/updater.rs`) walks an
ordered `MANIFEST_URLS` list — V2 first, V1 fallback — and uses whichever
responds first. Once V2 has been the source of truth for a release cycle
without incident, V1 will be retired from the pipeline.

`version.json` also carries the SHA256 hash of the installer so HD's build
pipeline can verify the download before bundling.

## Asset naming convention (v1.8.113+)

The Adom Desktop wiki page hosts TWO distinct types of artifacts per release:

1. **Full AD GUI installer** — the actual desktop app (Tauri window, bundled
   bridges, relauncher). One per OS / architecture.
2. **CLI companion binary** — a separate executable that talks to AD over
   the relay. Used by HD's WSL2 container, gallia builds, sibling-app
   installers, cron jobs. Does NOT contain AD itself.

Both ship together at the same version (single `python scripts/bump-version.py
patch` bumps both, single `cargo tauri build` + `cargo build --release` in
`cli/` produces both, single `scripts/release-publish.sh` uploads both).

### Filename pattern

| Artifact | Wiki asset name pattern | Example (v1.8.113) |
|---|---|---|
| Full AD GUI — Windows | `Adom.Desktop_<ver>_windows_x64-setup.exe` | `Adom.Desktop_1.8.113_windows_x64-setup.exe` |
| Full AD GUI — macOS | `Adom.Desktop_<ver>_macos_<arch>.dmg` | `Adom.Desktop_1.8.113_macos_aarch64.dmg` (future) |
| Full AD GUI — Linux | `Adom.Desktop_<ver>_linux_<arch>.AppImage` | `Adom.Desktop_1.8.113_linux_x86_64.AppImage` (future) |
| CLI companion — Linux | `adom-desktop-cli_<ver>_linux_<arch>` | `adom-desktop-cli_1.8.113_linux_x86_64` |
| CLI companion — macOS | `adom-desktop-cli_<ver>_macos_<arch>` | `adom-desktop-cli_1.8.113_macos_aarch64` (future) |
| CLI companion — Windows | `adom-desktop-cli_<ver>_windows_<arch>.exe` | `adom-desktop-cli_1.8.113_windows_x64.exe` (future) |

The `_cli_` token in the middle is the only signal you need to know "this is
the companion, not the app." `linux_x86_64` always means Linux x86_64,
regardless of whether the file is a GUI installer or a CLI binary.

### After install, the binary name is `adom-desktop`

The wiki asset name disambiguates at FETCH time. At INSTALL time the binary
is renamed to `adom-desktop` so the command users type doesn't change:

```bash
# Linux example — install the CLI companion
curl -fL "https://wiki.adom.inc/api/v1/pages/adom-desktop/files/adom-desktop-cli_1.8.113_linux_x86_64" \
  -o /tmp/ad
sudo install -m 755 /tmp/ad /usr/local/bin/adom-desktop
adom-desktop --version
# → adom-desktop 1.8.113 (<sha>, built <ts>)
```

### Version.json `.cli` slot

The auto-update manifest (v1.8.113+) carries a typed `cli` sibling section
for the CLI binaries:

```json
{
  "manifest_version": 1,
  "version": "1.8.113",
  "windows": { "installer_url": ".../Adom.Desktop_1.8.113_windows_x64-setup.exe", ... },
  "cli": {
    "linux_x86_64": {
      "binary_url":      ".../adom-desktop-cli_1.8.113_linux_x86_64",
      "binary_filename": "adom-desktop-cli_1.8.113_linux_x86_64",
      "binary_sha256":   "...",
      "binary_size":     8012408
    }
  },
  "changelog_url": "...",
  "minimum_required": "1.3.30"
}
```

Pre-v1.8.113 readers ignore `.cli` entirely (additive schema; no
`manifest_version` bump required). The desktop AD's own auto-updater only
reads `.windows / .macos / .linux` for its GUI installer URL — it doesn't
touch `.cli`.

For HD / gallia / Docker-side fetchers, prefer the typed lookup:

```bash
# Best: read the URL out of the manifest (so the filename can evolve)
MANIFEST=$(fetch_manifest)
LINUX_CLI_URL=$(echo "$MANIFEST" | jq -r '.cli.linux_x86_64.binary_url')
LINUX_CLI_SHA=$(echo "$MANIFEST" | jq -r '.cli.linux_x86_64.binary_sha256')
curl -fL "$LINUX_CLI_URL" -o /tmp/ad
[ "$(sha256sum /tmp/ad | awk '{print $1}')" = "$LINUX_CLI_SHA" ] || exit 1
sudo install -m 755 /tmp/ad /usr/local/bin/adom-desktop
```

### Windows CLI is shipped with the NSIS (v1.8.114+)

Installing AD on Windows now drops the CLI companion next to the GUI exe
and adds the install dir to the user's PATH so PowerShell / Claude Desktop /
cmd find it without configuration:

```
%LOCALAPPDATA%\Adom Desktop\adom-desktop.exe        ← GUI (Windows subsystem)
%LOCALAPPDATA%\Adom Desktop\adom-desktop-cli.exe    ← CLI companion (Console subsystem)
%LOCALAPPDATA%\Adom Desktop\ad-relauncher.exe       ← visible self-restart helper
```

NSIS's POSTINSTALL hook prepends `%LOCALAPPDATA%\Adom Desktop` to
`HKCU\Environment\Path` (no UAC — user-level only) and broadcasts
`WM_SETTINGCHANGE` so freshly-opened shells pick up the change. Already-
open shells need a re-launch (OS limitation).

After install, in a fresh PowerShell:

```powershell
adom-desktop-cli --version
# adom-desktop 1.8.114 (<sha>, built <ts>)
adom-desktop-cli status
adom-desktop-cli screenshot_window '{"title-contains":"VS Code"}'
```

The CLI auto-discovers the local AD via direct-API probe at
`127.0.0.1:47200` — no relay needed when AD is on the same box. ~5ms RTT
for compatible verbs; verbs in AD's `cliRequired` list still flow through
a relay if one's running (HD's WSL2 distro typically owns the relay).

**Relay self-detect (v1.8.114+):** `adom-desktop-cli serve` checks for
another adom-desktop relay on `127.0.0.1:8766/health` before binding. If
one already answers, it prints a friendly note and exits cleanly without
starting a second relay (which would just sit idle — AD's WS client only
attaches to the first one it finds). Pass `--force-bind` to override.

PREUNINSTALL strips the PATH entry back out and rebroadcasts so an
uninstall of AD also gets PATH cleanup.

### Legacy alias migration window

Releases prior to v1.8.113 published the Linux CLI as `adom-desktop-linux`
(no version, no architecture). HD's WSL2 setup and a few cron-based
installers have that literal filename baked in.

To keep them working through the rename, v1.8.113 publishes BOTH names:

| Name | Status | Wiki URL (V2 / V1) |
|---|---|---|
| `adom-desktop-cli_<ver>_linux_x86_64` | **canonical, v1.8.113+** | V2 / V1 |
| `adom-desktop-linux` | **deprecated alias** — byte-identical copy | V2 / V1 |

Both files are byte-identical with the same SHA256. The legacy alias stays
through **v1.8.116**, then disappears. Migrate by then. Recommended pattern:

```bash
# Migration period (v1.8.113 → v1.8.115): try new name, fall back to alias
LINUX_CLI_URL_NEW=$(echo "$MANIFEST" | jq -r '.cli.linux_x86_64.binary_url // empty')
if [ -n "$LINUX_CLI_URL_NEW" ]; then
  curl -fL "$LINUX_CLI_URL_NEW" -o /tmp/ad
else
  # Falling back — likely talking to a pre-v1.8.113 manifest
  curl -fL "https://wiki.adom.inc/api/v1/pages/adom-desktop/files/adom-desktop-linux" \
    -o /tmp/ad
fi
```

Post-v1.8.116, the fallback branch dies; only the canonical name will exist.
