+# Verify uv.lock is in sync with pyproject.toml.  Blocking check — PRs

+#
+# For `pull_request` events, GitHub checks out `refs/pull/<N>/merge` by
+# default — a synthetic commit that merges your PR branch into the CURRENT
+# state of `main`.  That means the pyproject.toml evaluated here is
+# `main's pyproject.toml + your PR's changes to pyproject.toml`, not just
+# what's on your branch.
+#
+# Failure mode this creates: if `main` has advanced since you branched
+# (e.g. someone merged a PR that added a dep to pyproject.toml + its
+# corresponding uv.lock entries), your branch's uv.lock is missing those
+# new entries.  `uv lock --check` resolves against the merged pyproject
+# and sees a lockfile that doesn't cover all the current deps → fails
+# with "The lockfile at uv.lock needs to be updated."
+#
+# This can be confusing: `uv lock --check` passes locally (your branch
+# is internally consistent) but fails in CI (merged state isn't).
+#
+# Fix is to sync your branch with main and regenerate the lockfile:

+#
+# If you also changed pyproject.toml in your PR, `uv lock` handles that
+# at the same time — one regeneration covers both your changes and the
+# drift from main.
+#
+# This is the correct behavior!  The check is protecting main's Docker

-- Prefer small nanostores over component state when state is shared, reused, or read by distant UI.
-- Let each feature own its atoms. Chat state belongs near chat, shell state near shell, shared state in `src/store`.
-- Components that render from an atom should use `useStore`. Non-rendering actions should read with `$atom.get()`.
-- Do not pass state through three components when the leaf can subscribe to the atom.
-- Keep persistence beside the atom that owns it.
-- Keep route roots thin. They compose routes and shell; they should not become controllers.
-- No monolithic hooks. A hook should own one narrow job.
-- Prefer colocated action modules over hidden god hooks.
-- If a callback is pure side effect, use the terse void form:
-  `onState={st => void setGatewayState(st)}`.
-- Async UI handlers should make intent explicit:
-  `onClick={() => void save()}`.
-- Prefer interfaces for public props and shared object shapes. Avoid `type X = { ... }` for object props.
-- Extend React primitives for props: `React.ComponentProps<'button'>`, `React.ComponentProps<typeof Dialog>`, `Omit<...>`, `Pick<...>`.

 ### Critical rules
 
-1. **`termios` and `fcntl` are Unix-only.** Always catch both `ImportError` and `NotImplementedError`:
+1. **Never call `os.kill(pid, 0)` for liveness checks.** `os.kill(pid, 0)`
+   is a standard POSIX idiom to check "is this PID alive" — the signal 0
+   is a no-op permission check. **On Windows it is NOT a no-op.** Python's
+   Windows `os.kill` maps `sig=0` to `CTRL_C_EVENT` (they collide at the
+   integer value 0) and routes it through `GenerateConsoleCtrlEvent(0, pid)`,
+   which broadcasts Ctrl+C to the **entire console process group** containing
+   the target PID. "Probe if alive" silently becomes "kill the target and
+   often unrelated processes sharing its console." See [bpo-14484](https://bugs.python.org/issue14484)
+   (open since 2012 — will never be fixed for compat reasons).
+
+   **Preferred:** use `psutil` (a core dependency — always available):
+
+   ```python
+   import psutil
+   if psutil.pid_exists(pid):
+       # process is alive — safe on every platform
+       ...
+   ```
+
+   If you specifically need the hermes wrapper (it has a stdlib fallback
+   for scaffold-phase imports before pip install finishes), use
+   `gateway.status._pid_exists(pid)`. It calls `psutil.pid_exists` first
+   and falls back to a hand-rolled `OpenProcess + WaitForSingleObject`
+   dance on Windows only when psutil is somehow missing.
+
+   Audit grep for new callsites: `rg "os\.kill\([^,]+,\s*0\s*\)"`. Any hit
+   in non-test code is presumptively a Windows silent-kill bug.
+
+2. **Use `shutil.which()` before shelling out — don't assume Windows has
+   tools Linux has.** `wmic` was removed in Windows 10 21H1 and later. `ps`,
+   `kill`, `grep`, `awk`, `fuser`, `lsof`, `pgrep`, and most POSIX CLI tools
+   simply don't exist on Windows. Test availability with
+   `shutil.which("tool")` and fall back to a Windows-native equivalent —
+   usually PowerShell via `subprocess.run(["powershell", "-NoProfile",
+   "-Command", ...])`.
+
+   For process enumeration: PowerShell's `Get-CimInstance Win32_Process` is
+   the modern replacement for `wmic process`. See
+   `hermes_cli/gateway.py::_scan_gateway_pids` for the pattern.
+
+3. **`termios` and `fcntl` are Unix-only.** Always catch both `ImportError`
+   and `NotImplementedError`:
    ```python
    try:
        from simple_term_menu import TerminalMenu

+4. **File encoding.** Windows may save `.env` files in `cp1252`. Always

    ```
+   Config files (`config.yaml`) may be saved with a UTF-8 BOM by Notepad and
+   similar editors — use `encoding="utf-8-sig"` when reading files that
+   could have been touched by a Windows GUI editor.
 
-3. **Process management.** `os.setsid()`, `os.killpg()`, and signal handling differ on Windows. Use platform checks:
+5. **Process management.** `os.setsid()`, `os.killpg()`, `os.fork()`,
+   `os.getuid()`, and POSIX signal handling differ on Windows. Guard with
+   `platform.system()`, `sys.platform`, or `hasattr(os, "setsid")`:
    ```python
-   import platform
    if platform.system() != "Windows":
        kwargs["preexec_fn"] = os.setsid
+   else:
+       kwargs["creationflags"] = subprocess.CREATE_NEW_PROCESS_GROUP
    ```
 
-4. **Path separators.** Use `pathlib.Path` instead of string concatenation with `/`.
+   **Preferred:** for killing a process AND its children (what `os.killpg`
+   does on POSIX), use `psutil` — it works on every platform:
+   ```python
+   import psutil
+   try:
+       parent = psutil.Process(pid)
+       # Kill children first (leaf-up), then the parent.
+       for child in parent.children(recursive=True):
+           child.kill()
+       parent.kill()
+   except psutil.NoSuchProcess:
+       pass
+   ```
 
-5. **Shell commands in installers.** If you change `scripts/install.sh`, check if the equivalent change is needed in `scripts/install.ps1`.
+6. **Signals that don't exist on Windows: `SIGALRM`, `SIGCHLD`, `SIGHUP`,
+   `SIGUSR1`, `SIGUSR2`, `SIGPIPE`, `SIGQUIT`, `SIGKILL`.** Python's
+   `signal` module raises `AttributeError` at import time if you reference
+   them on Windows. Use `getattr(signal, "SIGKILL", signal.SIGTERM)` or
+   gate the whole block behind a platform check. `loop.add_signal_handler`
+   raises `NotImplementedError` on Windows — always catch it.
+
+7. **Path separators.** Use `pathlib.Path` instead of string concatenation
+   with `/`. Forward slashes work almost everywhere on Windows, but
+   `subprocess.run(["cmd.exe", "/c", ...])` and other shell contexts can
+   require backslashes — convert with `str(path)` at the subprocess boundary,
+   not inside Python logic.
+
+8. **Symlinks need elevated privileges on Windows** (unless Developer Mode is
+   on). Tests that create symlinks need `@pytest.mark.skipif(sys.platform ==
+   "win32", reason="Symlinks require elevated privileges on Windows")`.
+
+9. **POSIX file modes (0o600, 0o644, etc.) are NOT enforced on NTFS** by
+   default. Tests that assert on `stat().st_mode & 0o777` must skip on
+   Windows — the concept doesn't translate. Use ACLs (`icacls`, `pywin32`)
+   for Windows secret-file protection if needed.
+
+10. **Detached background daemons on Windows need `pythonw.exe`, NOT
+    `python.exe`.** `python.exe` always allocates or attaches to a console,
+    which makes it vulnerable to `CTRL_C_EVENT` broadcasts from any sibling
+    process. `pythonw.exe` is the no-console variant. Combine with
+    `CREATE_NO_WINDOW | DETACHED_PROCESS | CREATE_NEW_PROCESS_GROUP |
+    CREATE_BREAKAWAY_FROM_JOB` in `subprocess.Popen(creationflags=...)`.
+    See `hermes_cli/gateway_windows.py::_spawn_detached` for the reference
+    implementation.
+
+11. **`subprocess.Popen` with `.cmd` or `.bat` shims needs `shutil.which`
+    to resolve.** Passing `"agent-browser"` to `Popen` on Windows finds
+    the extensionless POSIX shebang shim in `node_modules/.bin/`, which
+    `CreateProcessW` can't execute — you'll get `WinError 193 "not a valid
+    Win32 application"`. Use `shutil.which("agent-browser", path=local_bin)`
+    which honors PATHEXT and picks the `.CMD` variant on Windows.
+
+12. **Don't use shell shebangs as a way to run Python.** `#!/usr/bin/env
+    python` only works when the file is executed through a Unix shell.
+    `subprocess.run(["./myscript.py"])` on Windows fails even if the file
+    has a shebang line. Always invoke Python explicitly:
+    `[sys.executable, "myscript.py"]`.
+
+13. **Shell commands in installers.** If you change `scripts/install.sh`,
+    make the equivalent change in `scripts/install.ps1`. The two scripts
+    are the canonical example of "works on Linux does not mean works on
+    Windows" and have drifted multiple times — keep them in lockstep.
+
+14. **Known paths that are OneDrive-redirected on Windows:** Desktop,
+    Documents, Pictures, Videos. The "real" path when OneDrive Backup is
+    enabled is `%USERPROFILE%\OneDrive\Desktop` (etc.), NOT
+    `%USERPROFILE%\Desktop` (which exists as an empty husk). Resolve the
+    real location via `ctypes` + `SHGetKnownFolderPath` or by reading the
+    `Shell Folders` registry key — never assume `~/Desktop`.
+
+15. **CRLF vs LF in generated scripts.** Windows `cmd.exe` and `schtasks`
+    parse line-by-line; mixed or LF-only line endings can break multi-line
+    `.cmd` / `.bat` files. Use `open(path, "w", encoding="utf-8",
+    newline="\r\n")` — or `open(path, "wb")` + explicit bytes — when
+    generating scripts Windows will execute.
+
+16. **Two different quoting schemes in one command line.** `subprocess.run
+    (["schtasks", "/TR", some_cmd])` → schtasks itself parses `/TR`, AND
+    the `some_cmd` string is re-parsed by `cmd.exe` when the task fires.
+    Different parsers, different escape rules. Use two separate quoting
+    helpers and never cross them. See `hermes_cli/gateway_windows.py::
+    _quote_cmd_script_arg` and `_quote_schtasks_arg` for the reference
+    pair.
+
+### Testing cross-platform
+
+Tests that use POSIX-only syscalls need a skip marker. Common ones:
+- Symlinks → `@pytest.mark.skipif(sys.platform == "win32", ...)`
+- `0o600` file modes → `@pytest.mark.skipif(sys.platform.startswith("win"), ...)`
+- `signal.SIGALRM` → Unix-only (see `tests/conftest.py::_enforce_test_timeout`)
+- `os.setsid` / `os.fork` → Unix-only
+- Live Winsock / Windows-specific regression tests →
+  `@pytest.mark.skipif(sys.platform != "win32", reason="Windows-specific regression")`
+
+If you monkeypatch `sys.platform` for cross-platform tests, also patch
+`platform.system()` / `platform.release()` / `platform.mac_ver()` — each
+re-reads the real OS independently, so half-patched tests still route
+through the wrong branch on a Windows runner.

 ## Quick Install
 
+### Linux, macOS, WSL2, Termux
+
 ```bash
 curl -fsSL https://raw.githubusercontent.com/NousResearch/hermes-agent/main/scripts/install.sh | bash
 ```
 
-Works on Linux, macOS, WSL2, and Android via Termux. The installer handles the platform-specific setup for you.
+### Windows (native, PowerShell) — Early Beta
+
+> **Heads up:** Native Windows support is **early beta**. It installs and runs, but hasn't been road-tested as broadly as our Linux/macOS/WSL2 paths. Please [file issues](https://github.com/NousResearch/hermes-agent/issues) when you hit rough edges. For the most battle-tested Windows setup today, run the Linux/macOS one-liner above inside **WSL2**.
+
+Run this in PowerShell:
+
+```powershell
+irm https://raw.githubusercontent.com/NousResearch/hermes-agent/main/scripts/install.ps1 | iex
+```
+
+The installer handles everything: uv, Python 3.11, Node.js, ripgrep, ffmpeg, **and a portable Git Bash** (MinGit, unpacked to `%LOCALAPPDATA%\hermes\git` — no admin required, completely isolated from any system Git install).  Hermes uses this bundled Git Bash to run shell commands.
+
+If you already have Git installed, the installer detects it and uses that instead.  Otherwise a ~45MB MinGit download is all you need — it won't touch or interfere with any system Git.
 
 > **Android / Termux:** The tested manual path is documented in the [Termux guide](https://hermes-agent.nousresearch.com/docs/getting-started/termux). On Termux, Hermes installs a curated `.[termux]` extra because the full `.[all]` extra currently pulls Android-incompatible voice dependencies.
 >
-> **Windows:** Native Windows is not supported. Please install [WSL2](https://learn.microsoft.com/en-us/windows/wsl/install) and run the command above.
+> **Windows:** Native Windows is supported as an **early beta** — the PowerShell one-liner above installs everything, but expect rough edges and please file issues when you hit them. If you'd rather use WSL2 (our most battle-tested Windows path), the Linux command works there too. Native Windows install lives under `%LOCALAPPDATA%\hermes`; WSL2 installs under `~/.hermes` as on Linux.  The only Hermes feature that currently needs WSL2 specifically is the browser-based dashboard chat pane (it uses a POSIX PTY — classic CLI and gateway both run natively).

-# Hermes Desktop
-
-Native Electron shell for Hermes. It packages the desktop renderer, a bundled Hermes source payload, and installer targets for macOS and Windows.
-
-## Setup
-
-Install workspace dependencies from the repo root so `apps/desktop`, `apps/dashboard`, and `apps/shared` stay linked:
-
-```bash
-npm install
-```
-
-Use the normal Hermes Python environment for local runs:
-
-```bash
-source .venv/bin/activate  # or: source venv/bin/activate
-python -m pip install -e .
-```
-
-## Development
-
-```bash
-cd apps/desktop
-npm run dev
-```
-
-`npm run dev` starts Vite on `127.0.0.1:5174`, launches Electron, and lets Electron boot the Hermes dashboard backend on an open port in `9120-9199`. This path is for UI iteration and may still show Electron/dev identities in OS prompts.
-
-Useful overrides:
-
-```bash
-HERMES_DESKTOP_HERMES_ROOT=/path/to/hermes-agent npm run dev
-HERMES_DESKTOP_PYTHON=/path/to/python npm run dev
-HERMES_DESKTOP_CWD=/path/to/project npm run dev
-HERMES_DESKTOP_IGNORE_EXISTING=1 npm run dev
-HERMES_DESKTOP_BOOT_FAKE=1 npm run dev
-HERMES_DESKTOP_BOOT_FAKE=1 HERMES_DESKTOP_BOOT_FAKE_STEP_MS=900 npm run dev
-```
-
-`HERMES_DESKTOP_IGNORE_EXISTING=1` skips any `hermes` CLI already on `PATH`, which is useful when testing the bundled/runtime bootstrap path.
-
-`HERMES_DESKTOP_BOOT_FAKE=1` adds deterministic per-phase delays to desktop startup so you can validate the startup overlay and progress bar. For convenience, `npm run dev:fake-boot` enables fake mode with defaults.
-
-On a fresh Hermes profile, Desktop shows a first-run setup overlay after boot. The overlay saves the minimum required provider credential (for example `OPENROUTER_API_KEY`, `ANTHROPIC_API_KEY`, or `OPENAI_API_KEY`) to the active Hermes `.env`, reloads the backend env, and then lets the user continue without opening Settings manually.
-
-## Dashboard Dev
-
-Run the Python dashboard backend with embedded chat enabled:
-
-```bash
-hermes dashboard --tui --no-open
-```
-
-For dashboard HMR, start Vite in another terminal:
-
-```bash
-cd apps/dashboard
-npm run dev
-```
-
-Open the Vite URL. The dev server proxies `/api`, `/api/pty`, and plugin assets to `http://127.0.0.1:9119` and fetches the live dashboard HTML so the ephemeral session token matches the running backend.
-
-## Build
-
-```bash
-npm run build
-npm run pack          # unpacked app at release/mac-<arch>/Hermes.app
-npm run dist:mac      # macOS DMG + zip
-npm run dist:mac:dmg  # DMG only
-npm run dist:mac:zip  # zip only
-npm run dist:win      # NSIS + MSI
-```
-
-Before packaging, `stage:hermes` copies the Python Hermes payload into `build/hermes-agent`. Electron Builder then ships it as `Contents/Resources/hermes-agent`.
-
-## Automated Releases
-
-Desktop installers are published by [`.github/workflows/desktop-release.yml`](../../.github/workflows/desktop-release.yml) with two channels:
-
-- **Stable:** runs on published GitHub releases and uploads signed artifacts to that release tag.
-- **Nightly:** runs on `main` pushes and updates the rolling `desktop-nightly` prerelease.
-
-The workflow injects a channel-aware desktop version at build time:
-
-- stable: derived from the release tag (for example `v2026.5.5` -> `2026.5.5`)
-- nightly: `0.0.0-nightly.YYYYMMDD.<sha>`
-
-Artifact names include channel, platform, and architecture:
-
-```text
-Hermes-<version>-<channel>-<platform>-<arch>.<ext>
-```
-
-Each run also publishes `SHA256SUMS-<platform>.txt` so installers can be verified.
-
-### Stable release gates
-
-Stable builds fail fast if signing credentials are missing:
-
-- macOS signing + notarization: `CSC_LINK`, `CSC_KEY_PASSWORD`, `APPLE_API_KEY`, `APPLE_API_KEY_ID`, `APPLE_API_ISSUER`
-- Windows signing: `WIN_CSC_LINK`, `WIN_CSC_KEY_PASSWORD`
-
-Stable macOS builds also validate stapling and Gatekeeper assessment in CI before upload.
-
-## Icons
-
-Desktop icons live in `assets/`:
-
-- `assets/icon.icns`
-- `assets/icon.ico`
-- `assets/icon.png`
-
-The builder config points at `assets/icon`. Replace these files directly if the app icon changes.
-
-## Testing Install Paths
-
-Use the package-local test scripts from this directory:
-
-```bash
-npm run test:desktop:all
-npm run test:desktop:existing
-npm run test:desktop:fresh
-npm run test:desktop:dmg
-npm run test:desktop:platforms
-```
-
-`test:desktop:existing` builds the packaged app and opens it normally. It should use an existing `hermes` CLI if one is on `PATH`, preserving the user’s real `~/.hermes` config.
-
-`test:desktop:fresh` builds the packaged app and launches it in a throwaway fresh-install sandbox. It sets `HERMES_DESKTOP_IGNORE_EXISTING=1`, points Electron `userData` at a temp dir, points `HERMES_HOME` at a temp dir, and launches through the bundled payload path without touching your real desktop runtime or `~/.hermes`.
-
-`test:desktop:dmg` builds and opens the DMG.
-
-`test:desktop:platforms` runs platform bootstrap-path assertions, including:
-- existing vs bundled runtime path selection semantics
-- WSL2 protection against Windows `.exe/.cmd/.bat/.ps1` overrides
-- platform-specific bundled runtime import checks (`winpty` vs `ptyprocess`)
-
-For fast reruns without rebuilding:
-
-```bash
-HERMES_DESKTOP_SKIP_BUILD=1 npm run test:desktop:fresh
-HERMES_DESKTOP_SKIP_BUILD=1 npm run test:desktop:existing
-HERMES_DESKTOP_SKIP_BUILD=1 npm run test:desktop:dmg
-```
-
-## Installing Locally
-
-```bash
-npm run dist:mac:dmg
-open release/Hermes-0.0.0-arm64.dmg
-```
-
-Drag `Hermes` to Applications. If testing repeated installs, replace the existing app.
-
-## Runtime Bootstrap
-
-Packaged desktop startup resolves Hermes in this order:
-
-1. `HERMES_DESKTOP_HERMES_ROOT`
-2. existing `hermes` CLI, unless `HERMES_DESKTOP_IGNORE_EXISTING=1`
-3. bundled `Contents/Resources/hermes-agent`
-4. dev repo source
-5. installed `python -m hermes_cli.main`
-
-When the bundled path is used, Electron creates or reuses:
-
-```text
-~/Library/Application Support/Hermes/hermes-runtime
-```
-
-The runtime is validated before use. If required dashboard imports are missing, it reinstalls the desktop runtime dependencies and retries.
-
-## Debugging
-
-Desktop boot logs are written to:
-
-```text
-~/Library/Application Support/Hermes/desktop.log
-```
-
-If the UI reports `Desktop boot failed`, check that log first. It includes the backend command output and recent Python traceback context.
-
-To reset bundled runtime state:
-
-```bash
-rm -rf "$HOME/Library/Application Support/Hermes/hermes-runtime"
-```
-
-To reset stale macOS microphone permission prompts:
-
-```bash
-tccutil reset Microphone com.github.Electron
-tccutil reset Microphone com.nousresearch.hermes
-```
-
-## Verification
-
-Run before handing off installer changes:
-
-```bash
-npm run fix
-npm run type-check
-npm run lint
-npm run test:desktop:all
-```
-
-Current lint may report existing warnings, but it should exit with no errors.
