The BOTS sidebar previewed each profile's most recently active session
(last_session) but clicking the row opened the pinned canonical chat —
two different session identities, so the preview described one
conversation and the click landed in another.
- profiles.list gains an optional preferred_session_ids param
({profile: session_id}): an exact, existence-checked per-profile
lookup that resolves hidden rows and compression lineages to the
live tip (the same resolver session.resume uses) and returns a
preferred_session summary alongside the unchanged last_session.
- The hermes-bots plugin sends its canonical-chat pins with each
roster poll and previews preferred_session ?? last_session.
- openBotCanonicalChat verifies pins through the precise resolver
instead of a paginated, hidden-excluding session.list window that
misjudged real hidden pins as gone; transient lookup failures no
longer clear the pin or mint a replacement chat.
- Grandfathering: a bot with history but no pin adopts the previewed
session on first open instead of minting a new empty chat — the
behavior the design comment already promised.
