Head commit for run: f2113f500392b5e57c81ddbd6b2320ab2a212d9a / Xinyuan Lin <[email protected]> fix(amber): loop expression scoping + fail loud on main-loop state errors Two correctness fixes from a pre-merge review of the loop operators. 1. Loop expressions with generator expressions / comprehensions / lambdas NameError'd on their own loop variables. eval_output / run_update / eval_condition / the generated open() ran user code with `eval/exec(expr, {}, namespace)` -- an empty globals plus a locals-only mapping. A nested genexp/lambda scope resolves free names against globals, so `all(x > threshold for x in items)` raised NameError on `threshold`. Pass the namespace as globals instead; strip the `__builtins__` that exec injects so it never reaches the persisted loop state. Initialization now runs through a guarded `LoopStartOperator.run_initialization` helper, matching the eval_output / run_update / eval_condition pattern (generated open() is now a one-line delegate). 2. State serialization (state.to_tuple -> to_json) for a LoopStart's produced state runs on the main loop thread inside _emit_and_save_state, outside DataProcessor's guarded executor session. A non-JSON-serializable loop variable (e.g. a numpy array) raised a TypeError that propagated through run()'s @logger.catch(reraise=True), killing the thread and hanging the workflow with no operator-facing error. Report it like a UDF error (exception manager + ERROR console message + EXCEPTION_PAUSE) instead, and have _process_end_channel hold the region (skip port_completed / complete) when such an error is reported, so it surfaces rather than silently completing with single-iteration results. Tests: TestLoopExpressionScoping (genexp/comprehension/lambda across eval_output/run_update/eval_condition/run_initialization, plus no `__builtins__` leak) and two main-loop tests (state-emit error is reported not fatal; end channel holds the region on a reported error).
