Adds gateway.profile_routes config that routes specific Discord
guilds/channels/threads (and other platforms) to different profiles.
The routing engine uses hierarchical specificity matching
(thread > channel > guild) with bounded LRU caching for forum post
resolution.
Routing result is stamped on source.profile by BasePlatformAdapter
.build_source() at inbound time. When gateway.multiplex_profiles is on,
the existing _profile_runtime_scope machinery picks up source.profile
and runs the whole turn inside the profile's HERMES_HOME — so memory,
skills, config, and secrets all resolve to that profile automatically.
No new isolation code is added; this PR only adds the routing decision
layer on top of the existing multiplexing infrastructure.
Configuration:
gateway:
multiplex_profiles: true
profile_routes:
- name: server-default
platform: discord
guild_id: "GUILD_ID"
profile: server-profile
- name: special-channel
platform: discord
guild_id: "GUILD_ID"
chat_id: "CHANNEL_ID"
profile: channel-profile
When multiplex_profiles is off, profile_routes is ignored (no behavior
change for single-profile gateways).
Tests: 29 unit tests covering specificity scoring, hierarchical
matching, path-traversal validation, and config parsing.
