Audience: contributors, reviewers, and maintainers. Use case: this vault follows a flag-don't-fabricate rule: anything that could not be verified is marked unknown and logged in the gaps report. The lists below are the work queue — pick an item, verify a source, and fill the gap.

Unverified primary sources (primary_source: unknown)

These entries could not be tied to a verifiable primary source. If you can locate the original program page, repository, or official document, update the entry and remove it from this list.

• German Sensor-Technology School Guide — German-language school guide on sensor-based hydroponics/aquaponics; no verifiable source located.
• Interactive Hydroponics Textbook — named resource not locatable; closest candidate is the University of Arkansas online greenhouse learning center.
• Hydro_mod (unverified) — open-source hydroponics repository named in the source survey; no matching repository verified.
• Vertical Farming Project (Open-Source, Student-Led, China) — reportedly replicated across Chinese institutions; primary source unverified.
• Tsinghua IT Grade 5 Textbook — Aquaponics Unit — textbook confirmed via teacher platforms, but the publisher's catalog page was not found.
• Chengdu 'Huiya Farm' School Labor Education Base — documented in state media and a seminar listing; no official program page located.

Entries with other unknown frontmatter fields

How to contribute

1. Read the schema rules in _schema.md (vault root) — controlled vocabularies and required sections apply to every edit.
2. Check the gaps report _gaps.md (vault root; being compiled alongside this index) for the full log of unknown fields, schema exceptions, and follow-up notes per entry.
3. When you fill a gap: update the entry's frontmatter, add the new source under its ## Primary Source section, refresh last_verified, and remove the entry from this MOC's lists.
4. New resources are welcome — create one file per resource in vault/entries/ following the schema, declare its MOCs in the mocs: field, and add it to the relevant hubs.
