tools/checkpoint_manager.py's CHECKPOINT_BASE and gateway/sticker_cache.py's CACHE_PATH are resolved once at import time via get_hermes_home(), which is a context-local ContextVar under the multiplexed gateway (multiple profiles sharing one process). Freezing the path at import time pins every later checkpoint/cache read-write to whichever profile's HERMES_HOME was active when the module was first imported -- the same bug class already fixed for cache dirs, skills_hub, rich_sent_store, and (this session) the OAuth/auth.json/ sessions.json paths. CheckpointManager is "owned by AIAgent" per-instance, but its methods read the frozen module constant directly instead of taking the store root from the instance, so a profile's CheckpointManager can read/write code-edit checkpoints into a different profile's store. Add a per-call resolver for each path, following the established "respect an existing test monkeypatch of the constant, otherwise re-resolve through get_hermes_home()" pattern so the extensive existing test seams in tests/tools/test_checkpoint_manager.py and tests/gateway/test_sticker_cache.py keep working unmodified.
