TMax-legacy-1K

Deterministic 1,000-task TMax legacy (short/moderate/complex) release validated under rootless native-aarch64 Apptainer with strict offline execution.

  • Upstream: allenai/TMax-15K@e3ded940596cc611c9815684ba51a7e8ee0cffc9 (ODC-BY)
  • Parent Harbor archive: laion/TMax-15K-Harbor@55a490a81eefcd0f183af6feedffc0691b74bf90
  • Selection seed: tmax-legacy-1k-final1k-v1 (never uses target-model reward)
  • Gate 1: oracle 3000/3000, no-op 3000/3000, zero exceptions

Contents

  • data/tasks.tar.zst — agent-visible Harbor task trees (no oracle/truth)
  • data/manifests/freeze-manifest.jsonl — exact 1,000 IDs, domains, complexities
  • data/manifests/exclusions.json — build/Gate-1 exclusions
  • provenance/oracle-hashes.jsonl — content-addressed solve.sh / truth hashes
  • validation/gate1-summary.json — aggregate Gate-1 evidence

Gold solution/solve.sh and source truth are hash-pinned but not agent-visible. Access the private oracle bundle under LAION ACL if you need replay scripts.

Reproduction 

# hashes
sha256sum -c SHA256SUMS
# extract agent-visible tasks
tar --use-compress-program=zstd -xf data/tasks.tar.zst

Gate-1 profile: jupiter-apptainer-aarch64-offline-v1 (BRIDGE_APPTAINER_NETWORK=none, rootless Apptainer, 3× oracle + 3× no-op).
