What this changes

Resolves contradictory Discogs guidance by distinguishing CC0 monthly dumps from restricted live API content.

  • Policy: Defines handling and redistribution rules for every planned source.
  • Gates: Adds explicit Discogs GO/NO-GO decisions and fail-closed licensing validation.

Checklist

  • Scoped to this change — no unrelated files swept in
  • Directory README.md updated (or none needed)
  • AGENTS.md updated if a working rule or convention changed

Playlist data

  • Sources touched: none
  • make check passes — cache rebuilt, verify.py green, zero-line cache diff — not applicable
  • Overrides changed: none
    Every override edit records a human decision, not an inference
  • publication-links.json entries come from real REST responses, not guessed IDs

Tooling

  • make lint and make test pass — not applicable
  • A regression test covers any bug fixed in an override path, parser heuristic, or gate — not applicable

Safety

  • No secrets: no .env*, ~/.czarchive.toml, API keys, OAuth tokens, or cookies
  • Superseded work moved to discarded/ with a README.md explaining why — none

🟡 Changes recommended

The new “normalized fact” definition conflicts with the material-handling profile table’s guidance about using “original editorial wording,” which would create ambiguous policy and could lead to prohibited copying.

Pull request overview

This PR updates the music-history-db technical implementation strategy spec to resolve the previously contradictory Discogs licensing guidance by separating CC0 monthly dumps from restricted live API content, and by adding a source-by-source policy plus an explicit “fail-closed” licensing exit gate.

Changes:

  • Clarifies which “structured foundation” sources are CC0 and explicitly excludes Discogs Restricted Data, MusicBrainz supplementary data, and non-Wikidata Wikimedia API content from that blanket statement.
  • Adds a detailed “Source Licensing and Redistribution Policy” section with material-handling profiles and explicit GO/NO-GO decisions per source.
  • Reframes the KEXP pilot documents as discovery-only/research material (not a publishable golden dataset source) and adds a source-access licensing exit gate.

| **CC0** | Use the named official API or dump and obey its access rules. | Raw data may be retained privately. Bulk raw data stays out of Git as a project policy. | May be stored with source URL, retrieval date, and `CC0-1.0`; use original editorial wording. | Avoid unnecessary source prose; material within the defined CC0 scope may be quoted. | Normalized facts and provenance may be committed; bulk raw data may not. | Normalized facts may be redistributed. Attribution is encouraged even when CC0 does not require it. |
| **ITEM** | Use only an approved API, download, or ordinary manual access. Check the license or rights statement for each item or collection. | Keep the minimum raw material privately only when its terms permit; record any retention limit. | Factual assertions in original wording may be stored with the item-level rights classification. | Only under the recorded open license, permission, or a documented legal exception; keep the quotation no longer than needed and attribute it. | Commit facts, citations, and rights metadata. Commit source content only when its license permits repository redistribution and all attribution/share-alike duties are met. | Publish facts and citations. Publish source content only when the item-level license or permission covers the artifact and its distribution. |
| **RESEARCH** | Manual research only; do not scrape, crawl, or bulk-extract. | Retain only private research notes and the minimum source excerpt allowed by the terms; never retain credentials or personal data. | Store only discrete facts in original wording after human review, with a citation; do not reproduce the source’s compilation or expression. | Only with permission or a documented legal exception, with attribution. | Do not commit raw responses, documents, media, or copied prose. Reviewed facts and citations may be committed. | Redistribute only reviewed facts, citations, and original summaries; no source media or prose. |
