Most Matrix clients auto-set a room name when creating a DM (e.g.
"Alice & Bot" from participant display names), so the old
`is_direct and not has_explicit_name` heuristic classified virtually
all client-created DM rooms as "room", forcing require_mention gating
in legitimate one-on-one DMs.
member_count is now the primary DM signal: <=2 members means the room
is necessarily a 1:1 conversation, regardless of m.direct or an explicit
name. A room that grew to 3+ members but is still in stale m.direct is
still classified as a room (conflict flag set). Falls back to the
m.direct + name heuristic when the count is unavailable.
Also hardens _get_room_member_count with a joined_members API fallback
when the cache-backed state_store is empty.
Salvaged from #48554 by @justemu onto the current plugin adapter path
(gateway/platforms/matrix.py -> plugins/platforms/matrix/adapter.py).
Fixes#48551
Follow-up to ScotterMonk's cron-truncation fix:
- Remove HERMES_DELIVERY_MAX_PLATFORM_OUTPUT env var. Behavioral config
belongs in config.yaml, not a new HERMES_* env var (.env is secrets
only). The actual bug is fixed entirely by the adapter-aware skip; the
configurable cap was unneeded scope. MAX_PLATFORM_OUTPUT is a constant
again, collapsing the max_output=0 disable branch and the
audit-vs-truncation threshold divergence.
- Flag the remaining verified-chunking adapters (slack, matrix, feishu,
mattermost, teams, whatsapp, whatsapp_cloud, weixin, bluebubbles,
yuanbao) with splits_long_messages=True so the fix covers the whole
bug class, not just Discord/Telegram. Each verified to chunk in its
own send() via truncate_message().
- SMS deliberately left False: it chunks for normal replies but a
multi-segment cron blast is cost-bearing; the 4000-cap + file save is
the safer default there.
- Update tests: drop the two env-override tests, add a test asserting a
save failure during truncation (non-chunking) propagates.
Salvage of PR #41284 onto current main. Relocates the last 9 inline messaging
adapters (+ satellites: telegram_network, feishu_comment/_rules/meeting_invite,
wecom_crypto, wecom_callback) from gateway/platforms/ into self-contained
bundled plugins under plugins/platforms/<x>/, discovered via the platform
registry. Strips the per-platform core touchpoints from gateway/run.py,
gateway/config.py, hermes_cli/gateway.py, hermes_cli/setup.py, and
tools/send_message_tool.py.
Carries forward the migration fixes (explicit enabled:false honored,
get_connected_platforms forces discovery, plugin is_connected via
gateway.get_env_value, logs --component gateway matches plugins.platforms.*,
matrix hidden on Windows).
Additionally ports config keys main added since the PR base: the matrix
plugin's _apply_yaml_config now also covers allowed_users,
ignore_user_patterns, process_notices, and session_scope (the inline
gateway/config.py matrix block gained these in the 1340 commits the PR sat
open; they would otherwise have been silently dropped on deletion).
