Two-in-one cleanup motivated by the chat hang in dev 2026-05-22.
The crash root cause from the guarded-task traceback:
UnboundLocalError: cannot access local variable 'get_setting'
where it is not associated with a value
File generation_task.py:257, in run_generation
think = (await get_setting(user_id, 'think_enabled', 'false'))...
generation_task.py imports get_setting at module top, but a later
'if voice_mode: from ... import get_setting' block scopes it as a
function-local. When voice_mode=False the local import never runs,
but Python had already flagged get_setting as local for the entire
body — the think_enabled read at line 257 hit UnboundLocalError.
The line itself was dead-weight anyway. With the conversation+curator
architecture: chat ships tools=[] (think on a no-tools pass is pure
latency cost; nothing for the model to reason ABOUT in tool-call
terms), and the curator hardcodes think=False already. The user
setting was a holdover from before the architecture pivot. Removing
it entirely is cleaner than fixing the scoping bug to preserve a
toggle nobody should be using:
- generation_task.py: think hardcoded False. Removed the get_setting
call (which fixes the UnboundLocalError as a side effect).
- SettingsView.vue: dropped the Enable model thinking checkbox, the
thinkEnabled / savingThinkEnabled refs, the saveThinkEnabled
function, and the think_enabled load step.
- Migration 0050: DELETE FROM settings WHERE key='think_enabled'
to clean up any stored rows.
