+TSSMRBench Public Dataset License Notice
+
+This release package contains a public redistribution form of the TSSMRBench dataset.
+
+1. Contents of this package
+
+This package includes:
+- author-created benchmark organization, schema, task design, and annotations;
+- normalized memory-unit descriptions ("memory_unit_text") derived from public upstream release histories;
+- question records, supporting-state links, and evaluation-oriented metadata;
+- source URLs pointing back to the upstream public materials.
+
+This package does not include the original raw release-note text fields used during internal construction.
+
+2. Upstream rights
+
+The benchmark instances are derived from public release materials of multiple upstream open-source repositories. Copyright and license interests in those upstream materials remain with their respective rightsholders.
+
+Because the upstream sources come from many repositories with different licenses, this package is distributed under a custom notice rather than a single standard open-data license.
+
+3. Permitted use
+
+Subject to applicable law and any upstream restrictions, this public package may be used for:
+- research;
+- benchmarking;
+- reproducibility;
+- non-deceptive academic comparison and analysis.
+
+4. Conditions
+
+If you redistribute, modify, or build upon this package, you must:
+- preserve this notice;
+- preserve attribution to TSSMRBench and the repository releasing this package;
+- preserve source traceability information when present;
+- not misrepresent derived benchmark text as the original upstream release text;
+- independently review upstream repository terms if your use depends on original-source licensing or commercial reuse.
+
+5. No warranty
+
+This package is provided "as is", without warranty of any kind, including without limitation warranties of correctness, fitness for a particular purpose, or non-infringement.
+
+6. Takedown / correction
+
+If an upstream rightsholder believes that any part of this redistribution should be corrected, limited, or removed, the maintainers request that you contact the repository maintainers so the release can be reviewed and updated.

+# TSSMRBench Official 300 Public Release
+
+## Dataset Summary
+
+This repository contains the public release package for **TSSMRBench**, a benchmark for evaluating whether an agent memory system can retrieve the **stage-correct temporal semantic state** from an evolving memory trajectory.
+
+The source material for this release is derived from public release histories of 300 influential GitHub repositories. For public redistribution, the package **removes the original `raw_text` release-note content** and retains only the normalized `memory_unit_text` representations, benchmark structure, question annotations, and source links.
+
+The release is distributed as a single merged public file:
+
+- `data/official_300_merged_public.json`: a single-file public merged release with the same scenario structure as the internal merged dataset, but with `raw_text` removed.
+
+## What TSSMRBench Evaluates
+
+TSSMRBench focuses on **temporal semantic state memory retrieval**. Each scenario is an evolving memory trajectory composed of versioned semantic states. The benchmark asks whether a memory system can retrieve the state evidence required by a query when several nearby versions are semantically related but temporally different.
+
+The benchmark contains three task families:
+
+- `single_state_lookup`: retrieve one stage-correct state.
+- `cross_version_comparison`: jointly retrieve two states and compare them.
+- `temporal_version_ordering`: recover several states and place them in the correct temporal progression.
+
+## Public Release Design
+
+This Hugging Face release is intended to be easier to redistribute and audit than the internal experiment package:
+
+- Original `raw_text` fields are removed.
+- Local absolute paths are removed.
+- `source_url` links are preserved for traceability.
+- `memory_unit_text` fields retain the normalized textual state descriptions used in the benchmark.
+
+## Data Fields
+
+The merged file `official_300_merged_public.json` stores one scenario record per repository. Each scenario contains:
+
+- `prototype_id`: scenario identifier.
+- `repo`: source repository.
+- `window_title`: scenario title.
+- `window_summary`: summary of the scenario's version history.
+- `chunks`: the 30 temporal semantic state nodes, each with fields such as `memory_node_id`, `artifact_ref`, `time_hint`, `published_at`, `source_url`, and `memory_unit_text`.
+- `questions`: the benchmark questions associated with the scenario, including `question_id`, `task_type`, `query_text`, `options`, `correct_option_id`, `expected_answer`, `source_chunk_ids`, and `answer_support`.
+
+## Intended Use
+
+This release is intended for:
+
+- benchmarking agent memory systems;
+- retrieval and reranking analysis on evolving memories;
+- error analysis on version-sensitive memory retrieval;
+- research on temporal reasoning grounded in retrieved memory evidence.
+
+## Limitations
+
+- The package is derived from public repository release histories and therefore reflects the style, granularity, and coverage of those sources.
+- `memory_unit_text` is a normalized rewrite of source material rather than the raw release note text.
+- This public package is designed for benchmark use and traceable redistribution, not as a substitute for the original upstream release documentation.
+
+## Licensing Note
+
+This dataset package uses `license: other` because it combines:
+
+- benchmark structure, task design, and annotations created by the authors; and
+- derived state descriptions and source links originating from multiple upstream repositories with non-uniform licenses.
+
+Please read the `LICENSE` file in this repository before redistribution or reuse.
+
+## Citation
+
+If you use this dataset, please cite the TSSMRBench paper and repository once the final bibliographic entry is available. Until then, please reference the repository URL directly.
