Adolanium review §3 (Medium/Low). BASE shape at every steer/redirect/persist/agent-cache
lock site was: lock = getattr(obj, "_x_lock", None); if lock is not None: with lock: <direct
attribute read>; else: <getattr fallback for object.__new__ test stubs>. The refactor rewrote
several of these as 'with getattr(...) or nullcontext(): getattr(slot, None)', which (a) turned a
missing slot under the lock from a loud AttributeError into silent None and (b) in the gateway
peek helper read the cache without any lock when the lock attribute was absent.
Restored BASE semantics at:
- agent/agent_runtime_helpers.py::_requeue_pending_steer
- agent/interrupt_control.py: steer, redirect, clear_interrupt, _has_pending_redirect,
_drain_pending_redirect, _drain_pending_steer (new _ic_slot helper: direct read under lock)
- agent/session_persistence.py::_persist_lock (explicit None check + BASE rationale)
- gateway/slash_commands.py::_cached_agent_for (BASE callers read ONLY under the lock; no lock -> None)
- gateway/run_agent_cache.py::_evict_cached_agent (BASE: self._agent_cache direct under lock)
- agent/client_lifecycle.py::_is_openai_client_closed: BASE body + docstring verbatim (outer
is_closed first; inner _client.is_closed only when _client exists; else False)
- agent/stream_delivery.py::_ensure_stream_writer_state: restore BASE rationale that the lock is
created unconditionally in agent_init (_STREAM_STATE) and the lazy path is stub-only
A/B (/tmp/rf/rev/ab_lock_fallbacks.py, ab_client_closed.py) is byte-identical BASE vs HEAD on
the reviewer's inputs + edge cases. tests/agent/test_lock_fallback_base_semantics.py pins it
(7 of 25 cases fail on the pre-fix tree).
For each issue anchor present in BASE 63279301bc non-test .py and absent on HEAD, the BASE comment/docstring block was re-attached at the HEAD location of the code it explained (matched by the distinctive code line / enclosing def). Sentences already covered by an existing HEAD comment were deduped; the issue number always survives. Insert-only: no code lines changed.
AST-driven, body-identical move of 359 GatewayRunner methods into cohesive
mixin modules (gateway/run_{voice,adapters,topics,turn,shutdown,busy,
config_loaders,startup,watchers,notifications,inbound,goals,agent_cache}.py)
plus TurnRunner -> gateway/run_turn_runner.py. run.py-internal symbols are
imported lazily inside method bodies so patch('gateway.run.X') keeps
intercepting; neutral deps are top-level; logger name stays 'gateway.run'.
_UNSET moved to leaf gateway/run_common.py (def-time default-arg sentinel).
Whole-module inspect.getsource(gateway_run) AST-walker tests repointed to
the module that now holds the walked code.
