"""Matrix crypto store must be pinned per profile at connect(), not at import.

Under ``gateway.multiplex_profiles`` one process imports
``plugins.platforms.matrix.adapter`` once; the old module-level
``_STORE_DIR``/``_CRYPTO_DB_PATH`` resolved against the root HERMES_HOME at
import time, so every profile's adapter opened the SAME crypto.db and inbound
E2EE failed with "no session found" (#89168). ``connect()`` calls
``_resolve_store_dir()`` inside ``_profile_runtime_scope`` (context-local
HERMES_HOME), so resolving there -- and caching on the instance -- gives each
profile its own store. Exercised via ``_resolve_store_dir`` directly so the
test needs no mautrix install.
