+# MoE Rankings
+
+`meshllm/moe-rankings` is a public dataset of derived Mixture-of-Experts routing metadata for published model artifacts.
+
+The dataset stores ranking artifacts produced by `llama-moe-analyze` so tools such as `mesh-llm` can discover expert-hotness rankings for exact model revisions without recomputing them locally.
+
+## Purpose
+
+This dataset exists to provide:
+
+- immutable MoE expert rankings keyed by exact source model revision
+- a canonical archive of published ranking artifacts
+- reusable metadata for routing, sharding, and MoE placement experiments
+
+The dataset is not a model mirror and does not store original model weights.
+
+## Identity Model
+
+Each artifact is identified by:
+
+- `source_repo`
+- `source_revision`
+- `format`
+- `distribution_id`
+- `analyzer_id`
+
+For GGUF models, `distribution_id` is the normalized model distribution name, usually the GGUF filename stem with any shard suffix removed.
+
+## Layout
+
+Artifacts are stored under:
+
+```text
+data/<source_namespace>/<source_repo_name>/<source_revision>/<format>/<distribution_id>/<analyzer_id>/
+```
+
+Each artifact directory contains:
+
+- `metadata.json`
+- `ranking.csv`
+- `run.log`
+
+Example:
+
+```text
+data/Flexan/kshitijthakkar-qwen3.5-moe-0.87B-d0.8B-GGUF/a9b8adbec2cc87479c772dac1944f313b4036c26/gguf/qwen3.5-moe-0.87B-d0.8B.Q2_K/micro-v1/
+```
+
+## Artifact Semantics
+
+### `ranking.csv`
+
+Normalized expert ranking output with columns:
+
+```text
+expert_id,total_mass,mass_fraction,selection_count
+```
+
+Sorted by hottest experts first.
+
+### `metadata.json`
+
+Validation and provenance metadata, including:
+
+- exact source repo and commit
+- analyzed distribution id
+- file list and hashes
+- analyzer id
+- prompt set id
+- token count
+- local analyzer source details
+
+### `run.log`
+
+Raw execution log for debugging and auditing.
+
+## Analyzer Policy
+
+Current canonical analyzer:
+
+- `micro-v1`
+
+`micro-v1` is tied to a fixed built-in prompt set and should be comparable across runs. Any meaningful change to prompts or semantics should produce a new analyzer id such as `micro-v2`.
+
+## Immutability
+
+Artifacts in this dataset are intended to be immutable.
+
+- A new source model commit uses a new `source_revision` path.
+- A new analysis method or incompatible prompt set uses a new `analyzer_id`.
+- Existing published artifacts should not be overwritten with different content.
+
+## Intended Consumers
+
+- `mesh-llm`
+- MoE sharding and routing tools
+- benchmarking and evaluation pipelines
+- researchers comparing expert distributions across quantizations and revisions
+
+## Notes
+
+- This dataset stores derived metadata, not original model weights.
+- Some logs may be verbose because they preserve upstream tool output for reproducibility.
+- Model-repo colocated sidecars may exist separately, but this dataset is the canonical system of record.
