A missing API key is "no OpenRouter API key configured — set `OPENROUTER_API_KEY`", never "payment/credit error"; a failed request logs the exception class and message (secret-redacted) rather than an empty reason; a timed-out long job reports the timeout and where the job went, not a fallback-routing noise string. If you know the cause, say it; if you don't, say what you do know plus what to check — never a placeholder that points somewhere else.
- **Cross-platform**: Never assume Unix. See [Cross-Platform Compatibility](#cross-platform-compatibility)
### Fail loud at integration boundaries
**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.

providers intentionally do not run during cron.

turn, eviction, shutdown, `tui_gateway` teardown — and the CALLER binds the owning profile's scope
first (`_run_release_in_profile_scope`, `_session_profile_runtime_scope`); the agent never derives
its home from `os.environ` at flush time (`Path(_session_db.db_path).parent` is the ground truth).

# 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).

(implies code_file unless ``secret_file``): prefix-matched credentials become a
non-reusable sentinel (``«redacted:ghp_…»``) instead of a head/tail mask an agent
could write back into config.yaml as a dead credential.
Every regex sits behind a cheap substring gate that its pattern requires,
so the gates are never false-negative.
Set code_file=True to also skip the Python-repr mapping pass (``{'API_KEY': '…'}``
fixtures in source); pytest/exception diagnostic lines get a narrow pass in
redact_terminal_output instead.
Set file_read=True for file *content* returned to the agent (read_file / search_files / cat). The old
mask looked like a real-but-truncated key, so an agent reading it from config.yaml and writing it back
silently corrupted the stored credential into a dead 13-char value → 401 (issue #35519). The sentinel is
syntactically invalid as a token, so it can't be mistaken for a usable key or written back as one.
Set ``secret_file=True`` when the caller has already classified the SOURCE as secret-bearing
(``_is_secret_file_arg``: command reads on the terminal side, resolved tool paths on the
file side). It re-enables the ENV/JSON/YAML assignment passes that ``file_read`` would
otherwise skip, so an opaque prefix-less credential assigned to a credential-shaped key is
masked instead of passed through in cleartext (issue #110567). With ``file_read=True`` those
assignments are masked with the non-reusable sentinel, so the #35519 write-back hazard stays
closed. ``secret_file`` is authoritative: it wins over ``code_file``, so a caller cannot be
fail-open by setting both. Files that are not secret-bearing (any source file, a project's own
``config.yaml``) keep the code_file behaviour: ``MAX_TOKENS: 100`` and ``"apiKey": "test"``
fixtures are untouched.
