Rating Methodology (AAA-D)
How TrackForge M58 v1.1 catalogue and track ratings are calculated from the leakage taxonomy, agreement binding, ISWC coverage, population defects, and proof hashes.
Rating Input & Scoring Schedule
The public M58 v1.1 scoring contract for recomputing TrackForge AAA-D catalogue and track ratings from certified rating inputs.
Rating Contract & Maturity Model
How the Value Chain Maturity Model separates evidence maturity, royalty-leakage state and certificate-facing AAA-D ratings in TrackForge methodology.
Evidence Assembly & Leakage Projection
How TrackForge assembles source evidence, freezes it into evidence packets, and projects deterministic leakage taxonomy state.
Canonicalisation
How TrackForge canonicalises evidence packets, leakage vectors and rating events into deterministic JSON so identical inputs always produce identical hashes.
Hashing
How TrackForge uses SHA-256 to bind ratings to exact inputs: evidence packet hashes, rating event hashes and versioned methodology artefact hashes.
Merkle Tree Construction
How individual track hashes are assembled into a binary Merkle tree, producing a single root hash that commits to every track in a certification batch.
Blockchain Anchoring
How the Merkle root hash is anchored to a public blockchain via the OpenTimestamps protocol, creating a permanent and independently verifiable timestamp.
Independent Verification
How any party can independently verify a TrackForge certification without access to TrackForge systems, using standard cryptographic tools.
Re-Rating & Supersession
How re-rating works at TrackForge: new evidence or remediation creates a new versioned rating event and supersedes the old one without rewriting history.
