"""Per-turn context shared between ``GatewayRunner._run_agent_inner`` and the
``TurnRunner`` collaborator (gateway/run.py).
``_run_agent_inner`` historically defined its tool-progress plumbing as nested
closures (``progress_callback`` ~250 LOC, ``send_progress_messages`` ~353 LOC)
that closed over ~20 enclosing locals. ``TurnContext`` is the extraction seam:
each closed-over local becomes a field on this dataclass, so the closure bodies
can move onto ``TurnRunner`` methods unchanged modulo ``name`` -> ``ctx.name``
rewrites.
Field notes:
- All fields are written once by ``_run_agent_inner`` while wiring up the turn
(a few — ``_progress_metadata``, ``_progress_reply_to``, ``agent_holder`` —
are computed slightly later than construction and assigned onto the ctx as
soon as the original locals were bound). None of the original closures
*rebound* their captured names (no ``nonlocal``); mutable state uses the
same single-element-list containers as before (``last_progress_msg``,
``repeat_count``, ...), so mutation stays visible to the outer body through
the shared objects exactly as it did through the shared closure cells.
- ``_run_still_current`` stays a callable (it captures ``self``/
``session_key``/``run_generation``); carrying the callable keeps the
extracted bodies byte-identical.

"""Shared late-binding dependency seam for extracted dashboard routers.
Why this exists
---------------
``hermes_cli/web_server.py`` owns all dashboard runtime state: the ephemeral
``_SESSION_TOKEN``, the ``DASHBOARD_HEALTH`` singleton, config helpers, and a
large set of private helper functions the route handlers call. Extracted
``APIRouter`` modules under ``hermes_cli/web_routers/`` need those helpers, but
* importing ``web_server`` at module import time from a router module would be
a circular import (``web_server`` imports the router modules to mount them),
and
* re-homing the helpers/state here would break the many tests (and any third
party code) that ``monkeypatch.setattr(web_server, "_helper", ...)``.
Design: **late binding, state stays in web_server.** ``late(name)`` returns a
thin proxy that resolves ``hermes_cli.web_server.<name>`` *at call time*. This
is cycle-safe (the import happens inside the call, long after both modules are
initialised) and keeps ``web_server``'s runtime behaviour byte-identical:
monkeypatching an attribute on ``web_server`` is still authoritative because
every call re-reads the attribute from the live module.

done and must not be duplicated. Different controls in

NOT conclude "cua-driver can't drive this app" — climb the ladder. If
`delivery_mode="foreground"` returns `code:"foreground_unsupported"`, the
driver is too old; tell the user to update cua-driver.
`delivery_mode="foreground"` returns `code:"foreground_unsupported"`, the live
action schema lacks that property; choose another verified rung without
inferring support from the executable's reported version.
## Typed browser page rung
For page content in a supported GUI browser, the same `computer_use` tool
exposes namespaced `cua_browser_*` actions. They do not collide with other
browser tools. The contract is capability-based:
1. Discover the exact native browser `(pid, window_id)` with `list_windows` or
native capture, then call `cua_browser_state` with both values.
2. Continue only when it returns `status:"ok"`, `binding_quality:"exact"`, and
`mutation_allowed:true`. Select an opaque `tab_id` from that response.
3. Call `cua_browser_state` with the `tab_id` for a fresh `semantic_v2`
snapshot. Use only refs from that newest snapshot and only for their
declared actions.
4. Use the matching namespaced action (`cua_browser_click`,
`cua_browser_type`, `cua_browser_navigate`, or `cua_browser_pointer`).
Trusted input is the default. `input_route="dom_event"` is an explicit
trust downgrade; never choose it silently after a refusal.
5. Every mutation invalidates refs. Take a fresh state snapshot before another
typed action. Never chain actions from remembered refs.
`cua_browser_prepare` is a separate approved setup action. Driver-owned
`isolated_new`/`isolated_named` profiles require explicit `allow_launch=true`.
An `existing_profile` is decided by cua-driver's immutable permission mode.
Normal Hermes sessions use `standard`, which requires a certified protected
host and fails closed when Hermes has none. Explicit Hermes YOLO (`--yolo`,
`/yolo`, or `approvals.mode: off`) launches a private embedded cua-driver in
`unrestricted` after that risk acceptance, so there are no runtime Cua
approval prompts. Never invent, store, log, or reuse a grant token.
Use the native capture/AX/pixel/foreground ladder for browser chrome, browser
permission UI, OS prompts, native dialogs, extension surfaces, unsupported
engines, and any typed route that cannot prove exact binding or mutation
permission. `cua_browser_dialog` covers page JavaScript dialogs only.

The extraction contract: the closure bodies moved onto ``TurnRunner`` methods
byte-identically (modulo local -> ctx.field rewrites), with every closed-over
local carried as a ``TurnContext`` field. These tests pin the seam's wiring —
shared mutable containers, no-queue early returns — not the progress behavior

"""Session-scoped typed-browser routing for cua-driver.
The public model surface remains the single ``computer_use`` tool. This
module owns the stateful adapter between its namespaced ``cua_browser_*``
actions and cua-driver's raw ``get_browser_state`` / ``browser_*`` tools.
The adapter is deliberately stricter than the transport:
* native binding must be exact before mutation;
* the driver session id is injected by the adapter, never accepted from the
model;
* refs are usable only from the latest snapshot in this Hermes session;
* every mutation invalidates refs and requires a fresh state read; and
* changing from trusted input to ``dom_event`` is always explicit.
Browser preparation remains a separate approved action. Existing-profile
attachment is delegated to cua-driver's daemon authorization coordinator;
ordinary Hermes tool approval never substitutes for protected consent.

"""Seam for the server.py @method handler split (mechanical move).
server.py's ~130 JSON-RPC handlers close over its module globals
(``_sessions``, ``_ok``, ``_err``, config helpers, ...). To move them
out of the 19K-line module without rewriting a single handler body,
each ``methods_*`` module defines its handlers under a local
:class:`HandlerRegistry` and server.py calls :meth:`HandlerRegistry.install`
at the end of its own import, once every global the handlers close over
exists. ``install()`` rebinds each handler's ``__globals__`` to
server.py's namespace with ``types.FunctionType``, so handler bodies
stay byte-identical and ``global X`` statements inside handlers keep
mutating server.py state exactly as before the split.

## Permission modes and logged-in browser profiles
Hermes maps its existing approval UX onto cua-driver 0.10's immutable daemon
modes. There is no second permission toggle to keep in sync:
| Hermes session | cua-driver mode | Human intervention | `existing_profile` |
|---|---|---|---|
| Manual or smart approvals (default) | `standard` | Normal Hermes approvals; Cua stops at its protected boundary | Refuses unless a certified protected host is available; Hermes does not claim one today |
| `--yolo`, `/yolo`, or `approvals.mode: off` | private `unrestricted` daemon | One explicit Hermes risk acceptance; no runtime Cua prompts | Allowed within Cua's built-in, managed, and user policy ceilings |
The unrestricted daemon is private to that Hermes session. Turning `/yolo`
off, resetting/closing the session, cancellation cleanup, or process exit ends
the Cua session and stops that daemon. It never changes the machine-wide
daemon's mode or grants another Hermes conversation the same authority.
`smart` approval remains `standard`: an LLM classification is not protected
human consent. Cua's `bounded` manifest mode is also not inferred from smart
approval or a normal tool confirmation; it needs a separately trusted host
that reviews and launches the exact manifest.
<div class="alert alert--warning">
YOLO/unrestricted mode does not protect against prompt injection or unintended
input. Use it only in a disposable VM or with accounts and data whose full
compromise you accept.

### Notes & gotchas
- **Hermes spawns its own `cua-driver mcp` child over stdio** — it does
*not* attach to the long-running `cua-driver serve` autostart daemon
or its named pipe. So the scheduled task / LaunchAgent is unnecessary
for testing (`-NoAutoStart` is fine). The autostart daemon and the
Windows UIAccess worker (`cua-driver-uia.exe`) only matter for
foreground-safe input on some apps (e.g. WPF); the standard tool
surface works through the stdio child. On Windows SSH sessions, the
autostart pattern IS needed — see the Limitations section.
- **Hermes spawns a `cua-driver mcp` stdio proxy.** In a normal session the
proxy connects to (and may start) the standard machine daemon. In explicit
Hermes YOLO, Hermes instead owns a private `cua-driver serve --embedded`
child and points the proxy at its private socket or named pipe. The Windows
autostart/UIAccess pattern still matters for interactive Session 1+ input
from SSH — see the Limitations section.
- **Locked binary on Windows.** A running `cua-driver-serve` daemon can
hold `cua-driver.exe` and block an overwrite on rebuild.
`install-local.ps1` renames the locked binary out of the way

### "Listening" but receives silence (Windows)
Desktop push-to-talk and wake-word capture use different microphone paths.
Push-to-talk uses the desktop application's browser capture, while the
wake-word listener opens a PortAudio stream in the Python backend. One can work
while the other selects a silent or unusable Windows input.
`/wake status` reports the selected input device and Windows audio host API.
When it reports silence, set `wake_word.input_device` to the numeric index or an
unambiguous name of the working PortAudio input, then toggle the wake word:
