 The `SODA_2026/legacy_v1_6_decycled_gemini_3_8_flash` split contains all 142 SODA 2026 DAGs from [`AI-Math-TCS/tcs_dataset_v1_6_dags`](https://huggingface.co/datasets/AI-Math-TCS/tcs_dataset_v1_6_dags), pinned to source revision `d73772c60fd1770939fef4ed7d6db0b9b81e788b`. Procedural cycle detection found cycles in 53; Gemini 3.8 Flash (medium) proposed edge-only patches for those 53. All 142 published graphs passed a final acyclicity check, and node content was preserved. The other 89 graphs had no cycles and received no model repair call.
 
-This was **cycle-only** remediation, not a full re-validation or re-DAGification. Some source graphs have unrelated legacy structural issues (for example, missing or multiple primary parents or no overview node); those issues may remain. The original v1.6 dataset is unchanged. `had_cycles`, `num_original_cyclic_components`, `num_cycle_repair_rounds`, `cycle_repair_log`, `legacy_structural_issues`, and the source revision/hash columns document each row. The split name identifies the source and repair model; it does **not** imply Gemini generated the original DAG nodes.
+This was **cycle-only** remediation, not a full re-validation or re-DAGification. After cycle removal, 86 of 142 graphs still fail the current non-cycle structural gate (for example, missing or multiple primary parents or unknown endpoints); 11 have no overview node. These were not repaired in this pass. The original v1.6 dataset is unchanged. `had_cycles`, `num_original_cyclic_components`, `num_cycle_repair_rounds`, `cycle_repair_log`, `legacy_structural_issues`, and the source revision/hash columns document each row.
