Summary: Fix multiple bugs in ax/core and ax/orchestration: - `Arm.md5hash` hashes unconverted parameters instead of the numpy-type-converted `new_parameters` (core/arm.py:94) - `GeneratorRun.clone()` doesn't copy `gen_metadata` or `candidate_metadata_by_arm_signature`, causing mutations on the clone to affect the original (core/generator_run.py:304-346) - Module-level dict mutation in `OutcomeConstraint`: writing `fmt_data["name"] = ...` mutates the shared module-level dicts `UPPER_BOUND_MISMATCH` / `LOWER_BOUND_THRESHOLD` etc. (core/outcome_constraint.py:123,159) - Typo in method name: `is_reconverable_fetch_e` → `is_recoverable_fetch_e` (core/metric.py:168, orchestration/orchestrator.py:2098) - `force_refit` parameter hardcoded to True instead of using the passed argument (orchestration/orchestrator.py:1230) - Grammar fix: "values is better" → "values are better" (core/outcome_constraint.py) - Missing spaces between concatenated strings (core/parameter.py, core/parameter_constraint.py, core/experiment.py) Differential Revision: D92879435
Summary: Fix multiple bugs in ax/storage: - Missing `raise` before `SQADecodeError` silently ignores JSON mismatches during `copy_db_ids` (sqa_store/utils.py:114) - `int(None)` crash in SQA encoder: `metric_registry.get()` can return None, but the result was immediately passed to `int()` before the None check could run (sqa_store/encoder.py:393) - `AttributeError` on None kwargs in JSON decoder: `kwargs.pop()` was called before the `if kwargs is not None` guard (json_store/decoder.py:1092) - `decode_args_list` length mismatch in SQA save: used `len(trials)` instead of `len(trials_to_reduce_state)` and `[...] * len(trials)` instead of a single-element list (sqa_store/save.py:245,254) - SQLAlchemy filter no-op: `SQAExperiment.id is not None` uses Python identity check instead of SQLAlchemy's `.isnot(None)` (sqa_store/load.py:760) - Inconsistent threshold in error message: says "> 10" but the actual check is `> 15` (sqa_store/utils.py:77) - Garbled error message in with_db_settings_base.py: sentence fragments in wrong order (sqa_store/with_db_settings_base.py:106) - Doubled path `ax/ax/storage` in error message (sqa_store/encoder.py:131) - Backslash line-continuation inside string literal causes 16 extra spaces in error message (sqa_store/encoder.py:654) - Missing space between concatenated strings (sqa_store/db.py) - Typo "SCalarized" → "Scalarized" (sqa_store/encoder.py) - Missing space in SKIP_ATTRS_ERROR_SUFFIX (sqa_store/utils.py) Differential Revision: D92879499
Summary: Fix multiple bugs in ax/generation_strategy: - `min_trials_observed or ceil(...)` fails when `min_trials_observed=0` is explicitly passed: Python truthiness treats 0 as falsy, so the explicit value is discarded in favor of the default. Changed to `is None` check (dispatch_utils.py:61,127) - `max_parallelism_override and max_parallelism_cap` truthiness check misses explicit 0 values for the same reason. Changed to `is not None` checks (dispatch_utils.py:441) - Wrong variable in dedup check: `ObservationFeatures` object compared against list of `TParameterization` dicts instead of comparing `o.parameters` (external_generation_node.py:199) - Generation node setting wrong `_previous_node_name`: was setting it to the node being transitioned *to* instead of the node being transitioned *from* (generation_strategy.py:546) - Grammar fixes: "you are should" → "you should", "more is are available" → "more data is available" (generation_strategy.py, transition_criterion.py) Differential Revision: D92879532
Summary: Fix multiple bugs in ax/adapter: - `IntRangeToChoice` transform using index instead of value for `target_value`: `next(i for i, v in enumerate(values) if v == p.target_value)` returns the index, but the target_value should remain the value itself since ChoiceParameter stores actual values (transforms/int_range_to_choice.py:70) - Wrong exception type caught in `relativize.py`: `list.index()` raises `ValueError`, not `IndexError` or `StopIteration` (transforms/relativize.py:338) - Error message says "True" when the value is actually False: `use_model_predictions` is False in the branch where the error is raised (adapter_utils.py) - Missing space between concatenated strings (torch.py, adapter_utils.py) Differential Revision: D92879576
Summary: Fix multiple bugs in ax/service: - `max_parallelism or num_trials` fails when `max_parallelism` is 0: Python truthiness treats 0 as falsy, so an explicit 0 is replaced with `num_trials`. Changed to `is not None` check (ax_client.py) - `_is_all_noiseless` operator precedence + NaN comparison always returning False: `(sems == 0) | sems == nan` parses as `((sems == 0) | sems) == nan`, and NaN never equals anything. Fixed by using `.isna()` (utils/best_point.py:649) - Removed unused `from numpy import nan` import after the `_is_all_noiseless` fix (utils/best_point.py) - Typos: "exhaused" → "exhausted" (managed_loop.py), "Hieararchical" → "Hierarchical" (utils/instantiation.py) - Missing spaces between concatenated strings (utils/instantiation.py, utils/report_utils.py, ax_client.py) - Grammar fix: "by setting passing" → "by passing" (ax_client.py) Differential Revision: D92879656
