the bug #
end_session returned "Session ended." but did nothing structurally different from wait. there are two persistence files:
session.json- the full conversation (written by saveRuntimeSnapshot).nano-rest-snapshot.json- a summary only
on wake, boot checks loadSession() (session.json) first and restores every message verbatim + a "harness restarted" note. only if it's absent does it fall through to the summary bootstrap.
end_session saved a rest snapshot but never deleted session.json - so the next event rehydrated the entire prior context. observable from the outside: the agent kept waking with full history right after 'ending'.
the fix #
call clearSession() in the handler before resting, deleting session.json. the next wake then bootstraps fresh from the rest-snapshot summary. verified the rest path (finally block) does not re-save the session, so the clear survives to the next wake. tsc clean.
one file changed.
