The Dodge 400 was a mid-size car built by Dodge. It was similar to the Chrysler LeBaron of the same era. The 400 was introduced for the 1982 model year but renamed and merged into the Dodge 600 lineup just two years later. An improved version of Chrysler's K-cars, it was called the Super K platform.

Compression-Aware Abstention — labeled datasets
Compression-labeled training and evaluation data for "Compression-Aware Abstention" (GroundLM @ EMNLP 2026). Derived from MuSiQue 2-hop QA (CC BY 4.0, Trivedi et al., TACL 2022).
Each record pairs a MuSiQue example with a KV-cache compressor's per-token survival mask at one of six retention ratios, plus the label that mask implies.
Fields
| Field | Meaning |
|---|---|
id |
MuSiQue example id (2hop__*) |
ratio |
Target retention ratio: 0.05, 0.10, 0.20, 0.30, 0.50, 0.80 |
kept_mask |
Per-token boolean survival mask over the tokenized context |
label_type |
confident_answer or abstain |
target_output |
Gold answer, or the fixed refusal string |
supporting_spans |
Tight answer-bearing token ranges used for labeling |
metadata |
Compressor name, base model, context length |
Labels follow the rule in the paper: confident_answer when every supporting
span retains at least 0.8 of its tokens, abstain when any span falls below
0.3, dropped otherwise. Masks are generated by the same base model that
consumes them, since eviction patterns are model-specific.

Training splits apply a 30/70 minority-class floor; validation splits keep the natural class distribution. Train and validation are disjoint by example id.
Caveats
- The class distribution is U-shaped in the retention ratio: almost all
abstainat low retention, almost allconfident_answerat high. Only the r=0.50 slice is close to balanced. Aggregate metrics over the full set reward a policy that thresholds on the ratio alone without reading the context. - Tight-span survival is a surrogate for contextual sufficiency. On a stratified 400-example audit it reaches Cohen's kappa 0.61 against an LLM-judge verdict; disagreements concentrate on multi-hop questions where the answer string survives but the bridging evidence does not.
