Questions and exclusions

Required questions

1. Required question 1 (exact ID: question-1)
   Does the official source establish the entity, current program, and bounded capability described?
2. Required question 2 (exact ID: question-2)
   Are potential fit, risks, access, geography, and engagement boundaries current and proportionate?
3. Required question 3 (exact ID: question-3)
   Could any wording imply partnership, endorsement, availability, procurement, authority, or affiliation that does not exist?

Explicit exclusions

• Indexing is not endorsement, due diligence completion, outreach, procurement, or a relationship.
• No aggregate organization score or sponsor-purchased ranking is permitted.

Requested controlled scopes: ecosystem-due-diligence, information-science

Frozen-evidence decision window: 90 days from the packet freeze. Not applicable to this packet family.

Complete primary record set

Every record below has one primary packet owner. Decisions must bind to the exact record and packet fingerprints; a changed lesson body, evidence grade, citation, locator, source snapshot, requirement, policy, release, or commit expires the old packet.

   Engagement

   Proposed only, subject to a future fit check and university facility rules: use published records first; consider a bounded experiment or data project only with preregistered boundaries and no claim of whole-system validation. No outreach, facility booking, commitment, or funding has occurred.

   Profile Summary

   University of Arizona's Biosphere 2 is a large controlled-environment research and education facility supporting work on ecosystems, water, climate, agriculture, and Earth-system processes. Its famous 1990s closure missions are historically informative but involved substantial intervention and do not demonstrate an autonomous space biosphere.

   Potential Fit

   Could support controlled ecology, nutrient, water, soil, atmosphere, agriculture, and human-habitat experiments, and provide essential lessons about closure claims, system boundaries, and transparent failure reporting.

   Risks

   1. The facility is Earth-based, gravity-bound, accessible to outside intervention, and not materially closed at generation-ship scale.
   2. Historical publicity can obscure oxygen, nutrient, species, management, and boundary failures.
   3. Facility schedules, research access, tourism operations, cost, and data rights constrain experiments.

   Evidence Boundary

   Official-link review: the site was reachable and describes current research, education, tours, facilities, and Earth-systems mission. This review does not treat Biosphere 2 as proof of closed-loop viability and did not independently assess all historical data, current access, or experiment capacity; independent review pending.

   Conflicts

   Conflicts were not assessed beyond publisher disclosure in this official-link review; university funding, tourism revenue, researchers, donors, and historical narrative interests were not independently investigated.

   What Would Change

   Open long-duration mass balances, intervention logs, replicated controlled experiments, current facility access terms, and tests with progressively tighter boundaries would refine fit.

Linked records—not review targets here

These records provide dependency or relationship context. Their decisions belong to their single primary packet, preventing double counting.

Frozen source snapshots

Source inclusion does not determine the disposition. Reviewers must inspect the cited locator and relation, note inaccessible material, and identify stronger or conflicting evidence.

Offline packet and worksheet

Downloads contain no reviewer contact details. Downloading does not create an account or store a review response in the GShips application. Ordinary provider request or analytics logs may record the download request. Work locally: the public site has no review account, upload endpoint, or decision-submission API.

Do not paste a completed decision, identity documents, private contact data, confidential conflict evidence, medical information, controlled material, or exploit details into a public form. Until a separately authorized private handoff exists, retain the completed worksheet locally.

Validate offline

Use Node.js 22.13.0 or later. Keep the packet, worksheet, completed decision, and all six kit files together in a local directory.

1. Download the six kit files below. Complete a copy of the JSON template offline and preserve its templateFingerprint.
2. Finalize a separate output file.

   node finalize-review-decision.mjs \
     --input DRAFT.json \
     --output COMPLETED.json

   This marks the copy complete and calculates an unkeyed canonical bundle fingerprint. A fingerprint detects changes; it is not a reviewer signature.

3. Validate the packet and completed copy.

   node check-review-decisions.mjs \
     --packet PACKET.json \
     --decision COMPLETED.json

   Add another --decision for each independent reviewer.

4. Interpret the result narrowly. A zero exit proves structural consistency only. Neither command appoints or qualifies a reviewer, establishes independence, accepts a decision, or authorizes publication.
