Under gateway.multiplex_profiles, secondary profiles are constructed
inside _profile_runtime_scope and their .env lives in the profile's
secret scope - gateway/run.py explicitly does NOT mutate os.environ with
it. Four adapters still read their AUTHORIZATION config via raw
os.getenv, so every secondary profile either (a) silently missed its own
env-only allowlists/policies (fail-closed: all DMs dropped at intake) or
(b) inherited the default profile's GATEWAY_ALLOW_ALL_USERS=true /
allowlists from the shared process env (fail-open admissions):
- weixin.py: WEIXIN_DM_POLICY / WEIXIN_ALLOWED_USERS /
WEIXIN_GROUP_ALLOWED_USERS / WEIXIN_ALLOW_ALL_USERS +
GATEWAY_ALLOW_ALL_USERS in _open_dm_opted_in
- yuanbao.py: YUANBAO_DM_POLICY / DM_ALLOW_FROM / GROUP_POLICY /
GROUP_ALLOW_FROM / ALLOW_ALL_USERS (new _yb_secret helper; AccessPolicy
hard-gates intake)
- signal.py: SIGNAL_GROUP_ALLOWED_USERS / SIGNAL_ALLOWED_USERS (new
_sig_secret helper; empty scoped group list previously meant "drop all
groups" silently)
- wecom/adapter.py: WECOM_DM_POLICY / WECOM_ALLOWED_USERS /
WECOM_GROUP_POLICY / WECOM_ALLOW_ALL_USERS + GATEWAY_ALLOW_ALL_USERS -
while credentials one line above already used _get_scoped_secret
- gateway/run.py::_own_policy_open_startup_violation: the open-policy
startup guard validated GATEWAY_ALLOW_ALL_USERS via raw os.getenv even
though its sibling dm/group reads already used the scoped _getenv
All reads now go through the canonical fail-closed scoped shape QQ's
_resolve_qq_secret already used (scope hit wins; unscoped single-profile
callers keep legacy os.environ behavior). Regression suite drives the
real scope contextvar across all four helpers plus the admission gates
and the startup guard, asserting both directions: profile values are
visible under multiplex, default-profile values never leak.
