MOBIUSI INCFocused on exactly-once processing semantics in distributed messaging and event streaming platforms, this dataset contains source code examples covering transactional production, consumer processing, state updates, deduplication, and commit coordination. It includes processing context, correctness assumptions, call and state dependencies, and code-change impact analysis targets for examining transaction boundaries, processing pipelines, and key invariants. It supports training and evaluation of models that reason about code dependencies, semantic risks, and correctness.
| Field | Type | Description |
|---|---|---|
| file_name | string | File name |
| source_code | string | Source code showing transactional production, consumer processing, state updates, deduplication, or commit coordination logic. |
| dependency_graph | object | Processing nodes and dependency edges inferred from call relationships and shared state. |
| mutation_request | string | The requested code modification to analyze and whether it may break exactly-once processing semantics. |
| dependency_context | object | Original dependency information for the source code, including call chains, shared state, and external services. |
| processing_pipeline | array | Event processing stages and transaction boundaries derived from the source code and context. |
| correctness_assessment | object | Overall judgment of whether the source code and its modification preserve exactly-once processing semantics under the stated assumptions. |
| exactly_once_invariants | array | Exactly-once processing invariants derived from the input example and its correctness assumptions. |
| correctness_requirements | array | Prerequisites explicitly stated in the example for exactly-once processing semantics to hold. |
| event_processing_context | object | Original configuration or runtime context related to the event platform, transactions, commits, and state storage. |
| mutation_impact_analysis | object | Inferred effects of the code change on transaction, deduplication, state update, and commit coordination semantics. |
