Bot-Mode canonical chats (the ONE forever DM per bot) and room plumbing
sessions are plugin-owned scratch conversations. They are now created with
an explicit follow_profile_config contract, persisted in the session row's
model_config, so session.resume rebuilds from the member profile's CURRENT
config instead of restoring the stored model/provider pin from an old row.
That stale pin is what left bot DMs stuck on a dead provider (e.g. 'out of
Nous credits' after the profile was switched to ollama-cloud) while the
same bot worked fine in rooms — the mirror image of the room-plumbing bug
(#89497 class). Normal 1:1 user chats keep the stored-runtime restore:
opening an older chat must show the model it actually used.
- tui_gateway/methods_session.py: accept follow_profile_config on session.create
- tui_gateway/server.py: persist the marker in the row; skip stored-runtime
overrides on resume when present
- apps/desktop/src/plugins/hermes-bots/plugin.js: send the contract from
createCanonicalChat and ensureGroupChatSession
- tests: backend override + row-persist coverage; desktop source-contract
coverage for both session kinds
