MathTree Snapshots

This dataset repository is the public sync point for MathTree.

MathTree is a verifier-backed mathematical discovery system. The canonical ledger is maintained privately by the operators. This repository only publishes read-only snapshots of that ledger so contributors can sync a local frontier, play locally, and produce source-only submission patches.

What This Repo Contains

• latest.json points to the current checkpoint and ordered delta chain.
• checkpoints/ contains full snapshot archives.
• deltas/ contains smaller updates after the latest checkpoint.

These files are distribution artifacts. They are not the canonical database and they are not a submission inbox.

How Contributors Use It

Install MathTree from the project source, then sync the latest public frontier:

LEAN_PROJECT_ROOT=packages/verifiers/lean4/lean
SNAPSHOT_INDEX_URL=https://huggingface.co/datasets/comfortably-dumb/mathtree-snapshots/resolve/main/latest.json

uv run mathtree --database-url sqlite:///data/local-frontier.db snapshot sync \
  --index "$SNAPSHOT_INDEX_URL" \
  --state-dir .mathtree/snapshots \
  --object-store-root data/local_object_store \
  --project-root "$LEAN_PROJECT_ROOT"

Then start a local patch game from that synced frontier:

uv run mathtree --database-url sqlite:///data/local-frontier.db play \
  --sync-state .mathtree/snapshots \
  --object-store-root data/local_object_store \
  --project-root "$LEAN_PROJECT_ROOT" \
  --game-dir .mathtree/patch-game

After playing, export a source-only submission patch:

uv run mathtree submit-patch from-game \
  --game-dir .mathtree/patch-game \
  --output-patch contribution.mtpatch.json

Submit contribution.mtpatch.json through the project submission channel. The MathTree operators evaluate patches against the latest canonical ledger and publish accepted changes back here as future deltas or checkpoints.

Operator Notes

Only maintainers should update this repository. The expected layout is:

latest.json
checkpoints/<snapshot-id>.tar.zst
deltas/<delta-id>.tar.zst

The snapshot sync command verifies archive hashes before applying any checkpoint or delta. Correctness comes from the signed-off manifest content and canonical MathTree event hashes, not from trusting a local cache.
