Under gateway.multiplex_profiles, Discord and Telegram authorization gates
(allowed/ignored channels, allowed users/roles, allow-all flags) were read
from process-global os.environ, populated first-writer-wins by the YAML->env
bridge in each adapter's _apply_yaml_config. The first profile to initialize
pinned its allow/deny lists — and its ALLOW_ALL flags — for every other
profile in the process (issue #72348, incl. the Telegram mirror reported in
the thread).
Fix (per-adapter-instance gate reads, whole class):
- gateway/authz_mixin.py: new _platform_gate_env — scope-authoritative gate
read: under an installed profile secret scope with multiplex active, a
missing key returns the default instead of falling through to os.environ
(which may hold another profile's value). Single-profile behavior is
byte-identical to os.getenv.
- Discord adapter:
- connect() snapshots all gate env vars (_GATE_ENV_KEYS) inside the owning
profile's runtime scope into a per-adapter dict; new accessors
(_get_allowed_channels/_get_ignored_channels/_get_allowed_users/
_get_allowed_roles/_get_no_thread_channels/_discord_allow_all_users/
_gateway_allow_all_users/_get_allow_bots) resolve snapshot -> config.extra
-> scope-aware env, replacing every raw os.getenv gate read: on_message
channel gates, _is_allowed_user allow-all flags, slash authorization,
fail-closed diagnostics, missed-message backfill, bot-message gating,
and _component_check_auth (component buttons).
- _apply_yaml_config always seeds gate values into PlatformConfig.extra
(incl. new allowed_roles / allow_all_users keys) and SKIPS the
process-global env writes when loading a profile-scoped config under
multiplex; the legacy first-writer env bridge is preserved verbatim for
single-profile deployments.
- _resolve_allowed_usernames no longer unconditionally rewrites
os.environ[DISCORD_ALLOWED_USERS] — under multiplex the resolved IDs stay
adapter-local (snapshot refresh); single-profile keeps the env rewrite.
- Telegram adapter (mirror of the same class): intake prefilter and
callback-auth fallbacks, _telegram_auth_env_configured, and the
allowed/ignored chats-topics-threads getters now read via the scoped gate
reader; _apply_yaml_config skips authorization env writes for
profile-scoped loads and seeds free_response_chats/ignored_threads extras.
Regression tests (tests/plugins/platforms/test_discord_gate_isolation.py):
two adapter instances with different allow-lists enforce their OWN lists
order-independently across message, slash, and component gates; negative
allow-all case proves profile A's open-access flag cannot authorize profile
B; username-resolution env-clobber; YAML-bridge seeding/skip matrix; and the
Telegram scoped-reader matrix. Sabotage-verified: reverting either the
Discord snapshot accessors or the Telegram scoped reader fails 12/2 tests
respectively.
Credit: builds on the per-adapter accessor direction of PR #72427
(@JonthanaHanh) and the scope-aware-reader approach validated live on v0.19.0
by @yournetworkplug-ctrl for the Telegram mirror; scope corrections from
jackjin1997's and cal88's analysis in the issue thread (allow-all flags,
unguarded username-resolution env write, per-site channel reads).
