+# Risk-Routed KV Exact-Recall Benchmark
+
+This dataset contains controlled synthetic exact-recall examples used to evaluate **risk-routed heterogeneous KV memory** policies for long-context Transformer inference.
+
+The benchmark is designed for testing whether a model can retrieve exact strings from long contexts under different KV-cache policies:
+
+- **Full KV**
+- **Uniform low-bit Quantized KV**
+- **Risk-routed heterogeneous KV**, where exact-critical spans stay in Full KV and background context is quantized
+
+## Tasks
+
+1. `single_needle`: retrieve a secret marker from a long filler context.
+2. `multi_needle`: retrieve the marker associated with a queried label such as BLUE.
+3. `kv_retrieval`: retrieve a key-value record such as a city access code.
+4. `code_string`: retrieve the exact string returned by a small code block.
+5. `date_negation`: retrieve the approved final date while ignoring a negated distractor.
+
+## Schema
+
+Each JSONL row has:
+
+```json
+{
+  "id": "single_needle-8192w-0",
+  "task": "single_needle",
+  "context_words_target": 8192,
+  "context": "...long context...",
+  "query": "Which marker was labeled as the secret marker?",
+  "gold": "MK53-4897X",
+  "distractors": ["ZX17-2044Q", "ALPHA-77K2"],
+  "choices": ["MK53-4897X", "ZX17-2044Q", "ALPHA-77K2"],
+  "exact_spans": ["MK53-4897X"],
+  "source": "synthetic_controlled_exact_recall"
+}
+```
+
+## Intended evaluation
+
+For forced-choice evaluation, compute answer sequence NLL for each candidate in `choices` after the context and query. The prediction is correct if the `gold` answer has the lowest NLL.
