+# 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

+Applies to TypeScript across Hermes: desktop, TUI, website, and future TS packages.
+
+- 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<...>`.
+- Table-driven beats condition ladders when mapping ids, routes, or views.
+- `src/app` owns routes, pages, and page-specific components.
+- `src/store` owns shared atoms.
+- `src/lib` owns shared pure helpers.

 ### 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).
