| # Single-Episode Diagnostics Index | |
| These outputs are local diagnostics built from the existing one-episode Xperience-10M artifacts. They are designed for manual verification while waiting for full multi-episode data access. | |
| ## Generated Analyses | |
| - `modality_ablation/`: compact ridge-head ablations across real feature blocks. | |
| - `timeline_overlay/`: existing prediction CSVs aligned to the episode timeline. | |
| - `alignment_stress/`: cross-modal retrieval under explicit time-shift perturbations. | |
| - `provenance.json`: input hashes, feature dimensions, and source artifact identifiers. | |
| ## Validity Boundaries | |
| - This is a single-episode diagnostic, not a full Xperience-10M benchmark. | |
| - Rows marked `not_computed` are intentionally left blank when train labels or valid splits are unavailable. | |
| - Rows marked `derived_perturbation` use real features with deliberate time shifts for stress testing. | |
| ## Counts | |
| - Ablation rows: 108; computed: 108. | |
| - Timeline overlay rows: 2079. | |
| - Alignment stress rows: 54. | |
| - Shared feature shape: 1161 windows x 8546 features. | |
