TG55 Factory Asset Provenance

Status

The bundled TG55 wave memories are preserved for engineering review but are not cleared for public distribution.

Technical evidence is consistent with procedural generation: every asset is a 2,048-frame mono 16-bit PCM single-period wave memory at 44.1 kHz; each filename suffix encodes the hexadecimal recipe seed; WAV and recipe timestamps are paired; and the runtime factory bank describes the files as generated assets. The audited workspace contains no matching source recordings or third-party attribution.

This evidence is not a legal proof of authorship. The original generator is absent, and the workspace cannot prove that no external recording, hardware ROM waveform, or other protected input influenced the files.

Preserved Generation Records

Track Resources/TG55/catalog.json, all nine recipe JSON files, and all nine WAV files together. The recipes contain family, seed, brightness, warmth, noise, metallicity, and acceptance state. They are the only surviving generation-event records. Resources/TG55ProvenanceManifest.json hash-locks the complete 19-file evidence set.

Clearance Paths

Resolve this blocker through one of these auditable paths:

  1. Recover the original generator and reproduce every fingerprint from the tracked recipes.
  2. Obtain a creator statement confirming mathematical/noise-only synthesis with no third-party recordings, extracted hardware ROM waves, or other restricted inputs.
  3. Replace all nine assets using a newly tracked deterministic generator whose implementation and inputs can be audited.

Every path must also record the rightsholder or authorized licensor, the ownership or authority basis, an explicit commercial embedding/distribution grant, signer and date, and a durable evidence reference. Reproducing bytes proves technical lineage; it does not by itself grant commercial rights.

Until one path is complete, public packages must exclude the TG55 wave memories or TG55 itself.
