  "userRuling": "User explicitly limited this project to noncommercial scientific outreach and authorized CC BY-NC/BY-NC-SA recordings with exact attribution. ND remains excluded.",
  "licenseScope": "Licenses apply per recording. Tagua derivative remains CC BY 4.0; pidén and huala derivatives remain CC BY-NC 4.0. A commercial reuse would require replacing the NC tracks or additional permission.",
  "verification": "Saved public iNaturalist API metadata verifies each sound-specific license, source identity, author, location and two current matching community identifications. License version confirmed against pinned official iNaturalist source code. Original media downloaded from the documented public static.inaturalist.org S3 origin; no access-control bypass.",
  "licenseVersionEvidenceLocal": "audio-sources/birds/inaturalist-license-module.txt",
  "limitations": "No human audition or independent bioacoustic verification performed. Source foreground identification is community research grade; possible background species or human/environmental noises are not independently identified. This is an evocative modern assemblage, not a measured ancient acoustic reconstruction.",
  "claimRecord": {
    "support": "Source files and individual API snapshots with SHA256; exact PCM measurements and sparse timing tests; primary TT3 article abstract separately documents the selected taxa.",
    "changesAfterResults": "Initial open-license-only search found no eligible huala or Chilean pidén. The explicit subsequent noncommercial user ruling broadened license eligibility, allowing Chilean BY-NC sources. An Argentine BY pidén alternative and a less certain second tagua observation were not used. Huala was preferred over perdiz as requested; sources remain complete, with no internal edits chosen to favor acoustic results.",
    "unresolved": "No listening-based quality approval; no proof of exact local/prehistoric vocal behavior; background calls may be present. Huala recording is from Aysén, not central Chile.",
    "decision": "User authorized NC scientific outreach; main agent requested these three taxa and owns final mixing, linked credits and integration. Scope and reporting remain source-specific."
