METR count_odds reviewer packet
A public-safe packet for one Flywheel task-image interoperability check, not a product release.
Download
This archive preserves the source pins, runner receipts, and verification notes needed to inspect Flywheel PR234's count_odds bridge path. This is interop evidence, not METR endorsement, a model benchmark, a safety certification, or a Flywheel 1.0 release claim.

SHA-256: 1a1a9ca19728f11935d93eb8ef14770fa4d78f82484df356ac22b4da929dcac0. The hash checks archive identity; it does not by itself prove semantic correctness.
What the packet covers
Flywheel PR234 added a minimal METR Task Standard import path and was merged on September 13, 2026. The retained run built the upstream count_odds task image in a runner-local registry, exercised three controls through a pinned Inspect bridge, and imported the run exports through a pinned Flywheel revision.

0, with the packet noting that upstream scorer fallback limits what this proves.

The public packet omits copied bridge source and built task images because the pinned bridge snapshot did not include a detected license file.
Verify locally
Extract the archive and use its bundled verifier against the exact Flywheel source checkout named in the packet README:
python .\tools\verify_packet.py --flywheel-source <flywheel-checkout> --out .\_verify\packet-verificationThe verifier checks the retained manifests, hashes, and referenced local packet structure. It does not rerun METR infrastructure or establish general conformance.
Scope boundary
The packet carries reported scorer outputs, source pins, and byte-level receipts for one public bridge exercise. It does not certify METR conformance, scorer semantic correctness, Flywheel installed release status, independent adoption, model safety, or Flywheel 1.0 readiness.
