feat(windows): close native-Windows install gaps — crash-free startup, UTF-8 stdio, tzdata dep, docs
Native Windows (with Git for Windows installed) can now run the Hermes CLI and gateway end-to-end without crashing. install.ps1 already existed and the Git Bash terminal backend was already wired up — this PR fills the remaining gaps discovered by auditing every Windows-unsafe primitive (`signal.SIGKILL`, `os.kill(pid, 0)` probes, bare `fcntl`/`termios` imports) and by comparing hermes against how Claude Code, OpenCode, Codex, and Cline handle native Windows. ## What changed ### UTF-8 stdio (new module) - `hermes_cli/stdio.py` — single `configure_windows_stdio()` entry point. Flips the console code page to CP_UTF8 (65001), reconfigures `sys.stdout`/`stderr`/`stdin` to UTF-8, sets `PYTHONIOENCODING` + `PYTHONUTF8` for subprocesses. No-op on non-Windows. Opt out via `HERMES_DISABLE_WINDOWS_UTF8=1`. - Called early in `cli.py::main`, `hermes_cli/main.py::main`, and `gateway/run.py::main` so Unicode banners (box-drawing, geometric symbols, non-Latin chat text) don't `UnicodeEncodeError` on cp1252 consoles. ### Crash sites fixed - `hermes_cli/main.py:7970` (hermes update → stuck gateway sweep): raw `os.kill(pid, _signal.SIGKILL)` → `gateway.status.terminate_pid(pid, force=True)` which routes through `taskkill /T /F` on Windows. - `hermes_cli/profiles.py::_stop_gateway_process`: same fix — also converted SIGTERM path to `terminate_pid()` and widened OSError catch on the intermediate `os.kill(pid, 0)` probe. - `hermes_cli/kanban_db.py:2914, 3041`: raw `signal.SIGKILL` → `getattr(signal, "SIGKILL", signal.SIGTERM)` fallback (matches the pattern already used in `gateway/status.py`). ### OSError widening on `os.kill(pid, 0)` probes Windows raises `OSError` (WinError 87) for a gone PID instead of `ProcessLookupError`. Widened the catch at: - `gateway/run.py:15101` (`--replace` wait-for-exit loop — without this, the loop busy-spins the full 10s every Windows gateway start) - `hermes_cli/gateway.py:228, 460, 940` - `hermes_cli/profiles.py:777` - `tools/process_registry.py::_is_host_pid_alive` - `tools/browser_tool.py:1170, 1206` ### Dashboard PTY graceful degradation `hermes_cli/pty_bridge.py` depends on `fcntl`/`termios`/`ptyprocess`, none of which exist on native Windows. Previously a Windows dashboard would crash on `import hermes_cli.web_server` because of a top-level import. Now: - `hermes_cli/web_server.py` wraps the pty_bridge import in `try/except ImportError` and sets `_PTY_BRIDGE_AVAILABLE=False`. - The `/api/pty` WebSocket handler returns a friendly "use WSL2 for this tab" message instead of exploding. - Every other dashboard feature (sessions, jobs, metrics, config editor) runs natively on Windows. ### Dependency - `pyproject.toml`: add `tzdata>=2023.3; sys_platform == 'win32'` so Python's `zoneinfo` works on Windows (which has no IANA tzdata shipped with the OS). Credits @sprmn24 (PR #13182). ### Docs - README.md: removed "Native Windows is not supported"; added PowerShell one-liner and Git-for-Windows prerequisite note. - `website/docs/getting-started/installation.md`: new Windows section with capability matrix (everything native except the dashboard `/chat` PTY tab, which is WSL2-only). - `website/docs/user-guide/windows-wsl-quickstart.md`: reframed as "WSL2 as an alternative to native" rather than "the only way". - `website/docs/developer-guide/contributing.md`: updated cross-platform guidance with the `signal.SIGKILL` / `OSError` rules we enforce now. - `website/docs/user-guide/features/web-dashboard.md`: acknowledged native Windows works for everything except the embedded PTY pane. ## Why this shape Pulled from a survey of how other agent codebases handle native Windows (Claude Code, OpenCode, Codex, Cline): - All four treat Git Bash as the canonical shell on Windows, same as hermes already does in `tools/environments/local.py::_find_bash()`. - None of them force `SetConsoleOutputCP` — but they don't have to, Node/Rust write UTF-16 to the Win32 console API. Python does not get that for free, so we flip CP_UTF8 via ctypes. - None of them ship PowerShell-as-primary-shell (Claude Code exposes PS as a secondary tool; scope creep for this PR). - All of them use `taskkill /T /F` for force-kill on Windows, which is exactly what `gateway.status.terminate_pid(force=True)` does. ## Non-goals (deliberate scope limits) - No PowerShell-as-a-second-shell tool — worth designing separately. - No terminal routing rewrite (#12317, #15461, #19800 cluster) — that's the hardest design call and needs a separate doc. - No wholesale `open()` → `open(..., encoding="utf-8")` sweep (Tianworld cluster) — will do as follow-up if users hit actual breakage; most modern code already specifies it. ## Validation - 28 new tests in `tests/tools/test_windows_native_support.py` — all platform-mocked, pass on Linux CI. Cover: - `configure_windows_stdio` idempotency, opt-out, env-preservation - `terminate_pid` taskkill routing, failure → OSError, FileNotFoundError fallback - `getattr(signal, "SIGKILL", …)` fallback shape - `_is_host_pid_alive` OSError widening (Windows-gone-PID behavior) - Source-level checks that all entry points call `configure_windows_stdio` - pty_bridge import-guard present in `web_server.py` - README no longer says "not supported" - 12 pre-existing tests in `tests/tools/test_windows_compat.py` still pass. - `tests/hermes_cli/` ran fully (3909 passed, 9 failures — all confirmed pre-existing on main by stash-test). - `tests/gateway/` ran fully (5021 passed, 1 pre-existing failure). - `tests/tools/test_process_registry.py` + `test_browser_*` pass. - Manual smoke: `import hermes_cli.stdio; import gateway.run; import hermes_cli.web_server` — all clean, `_PTY_BRIDGE_AVAILABLE=True` on Linux (as expected). ## Files - New: `hermes_cli/stdio.py`, `tests/tools/test_windows_native_support.py` - Modified: `cli.py`, `gateway/run.py`, `hermes_cli/main.py`, `hermes_cli/profiles.py`, `hermes_cli/gateway.py`, `hermes_cli/kanban_db.py`, `hermes_cli/pty_bridge.py`, `hermes_cli/web_server.py`, `tools/browser_tool.py`, `tools/process_registry.py`, `pyproject.toml`, `README.md`, and 4 docs pages. Credits to everyone whose prior PR work informed these fixes — see the co-author trailers. All of the PRs listed in `~/.hermes/plans/windows-support-prs.md` fixing `os.kill` / `signal.SIGKILL` / UTF-8 stdio / tzdata / README patterns found the same issues; this PR consolidates them.

fix(pty): default TERM for resize probes
Preserve explicit caller overrides, but backfill a sensible default TERM=xterm-256color when missing or blank in the spawn env. CI often runs without TERM in the parent process, which makes terminal probes like 'tput cols' fail before winsize reads. Salvage of #15278's core code fix only — the test changes conflict with subsequent test refactors on main that now exercise TIOCGWINSZ directly instead of via 'tput'.

feat(web): add /api/pty WebSocket bridge to embed TUI in dashboard
Exposes hermes --tui over a PTY-backed WebSocket so the dashboard can
embed the real TUI rather than reimplement its surface. The browser
attaches xterm.js to the socket; keystrokes flow in, PTY output bytes
flow out.
Architecture:
browser <Terminal> (xterm.js)
│ onData ───► ws.send(keystrokes)
│ onResize ► ws.send('\x1b[RESIZE:cols;rows]')
│ write ◄── ws.onmessage (PTY bytes)
▼
FastAPI /api/pty (token-gated, loopback-only)
▼
PtyBridge (ptyprocess) ── spawns node ui-tui/dist/entry.js ──► tui_gateway + AIAgent
Components
----------
hermes_cli/pty_bridge.py
Thin wrapper around ptyprocess.PtyProcess: byte-safe read/write on the
master fd via os.read/os.write (not PtyProcessUnicode — ANSI is
inherently byte-oriented and UTF-8 boundaries may land mid-read),
non-blocking select-based reads, TIOCSWINSZ resize, idempotent
SIGHUP→SIGTERM→SIGKILL teardown, platform guard (POSIX-only; Windows
is WSL-supported only).
hermes_cli/web_server.py
@app.websocket("/api/pty") endpoint gated by the existing
_SESSION_TOKEN (via ?token= query param since browsers can't set
Authorization on WS upgrades). Loopback-only enforcement. Reader task
uses run_in_executor to pump PTY bytes without blocking the event
loop. Writer loop intercepts a custom \x1b[RESIZE:cols;rows] escape
before forwarding to the PTY. The endpoint resolves the TUI argv
through a _resolve_chat_argv hook so tests can inject fake commands
without building the real TUI.
Tests
-----
tests/hermes_cli/test_pty_bridge.py — 12 unit tests: spawn, stdout,
stdin round-trip, EOF, resize (via TIOCSWINSZ + tput readback), close
idempotency, cwd, env forwarding, unavailable-platform error.
tests/hermes_cli/test_web_server.py — TestPtyWebSocket adds 7 tests:
missing/bad token rejection (close code 4401), stdout streaming,
stdin round-trip, resize escape forwarding, unavailable-platform ANSI
error frame + 1011 close, resume parameter forwarding to argv.
96 tests pass under scripts/run_tests.sh.
