   Thesis

   Before sending people, humanity must know far more about nearby worlds, indigenous life, long-term destination change, and the ethics of arrival.

   Current State

   1. Thousands of exoplanets are confirmed, while atmospheric characterization of small nearby worlds remains limited.
   2. Habitable zone means a range of possible stellar heating, not proof of life or human habitability.
   3. Robotic precursors and future direct-imaging observatories can reduce uncertainty before irreversible missions.

   Unknowns

   1. Atmosphere, surface pressure, radiation, geology, chemistry, climate stability, resources, and life status of candidate destinations are largely unknown.
   2. A target can change during centuries of travel or be revealed as unsuitable after departure.
   3. International legitimacy for settling or biologically seeding a world with credible indigenous life is unresolved.

   Earth Benefits

   1. Exoplanet and biosignature science improve understanding of Earth’s climate, atmosphere, and place in the universe.
   2. Planetary-protection methods strengthen biosafety, contamination control, and responsible exploration.

   Dependencies

   1. communications-navigation
   2. mission-architecture
   3. governance-law

   Gate

   No crew launch without high-confidence robotic characterization and a presumption against settlement where credible indigenous life is detected.

   Rationale

   Current science cannot establish the atmosphere, surface, biosphere, long-term stability, or settlement suitability of a nearby exoplanet, while planetary-protection and international-law instruments address contamination and state conduct without resolving interstellar settlement legitimacy. Requiring more knowledge before an irreversible crewed mission is a precautionary decision rule, not a finding that sufficient knowledge is guaranteed.

   1. GShips Project editorial synthesis

   Conflicts

   1. GShips has a mission-related interest in destination research, but this gate rejects destination marketing, settlement claims, biological release, or launch advocacy unsupported by independently reviewed evidence and legitimate authorization.

   What Would Change

   Repeated direct observations and robotic precursors would need to constrain atmosphere, surface, climate, resources, hazards, and life status, while a legitimate international process defines consent, contamination, noninterference, stewardship, and no-go rules. Even strong data might support wait or do-not-launch rather than settlement.

   1. GShips Project editorial synthesis

   Conflicts

   1. The project may benefit from public interest in a large planet count; the count will not be used to imply that any world is Earth-like, inhabited, settleable, available, or a GShips destination.

   What Would Change

   A maintained catalog could revise the count at any time. A statistically meaningful set of directly imaged small nearby planets with replicated atmospheric spectra, retrieval validation, stellar-context observations, surface or pressure constraints, and explicit false-positive analysis would narrow the characterization gap without proving settlement suitability.

   Conflicts

   1. GShips may communicate candidate destinations, but it has no interest in inflating habitable-zone membership into life, safety, property, settlement, or launch claims.

   What Would Change

   The definition would change only with a revised scientific convention, but a particular planet's status requires replicated atmosphere, pressure, temperature, water, radiation, surface, climate, and biosignature evidence. Those observations could make a candidate more or less promising without turning habitable-zone membership itself into proof.

If remote observations or precursors cannot resolve life status before irreversible commitment, the proper gate may remain wait or do-not-launch.

   1. GShips Project editorial synthesis

   Conflicts

   1. Long-voyage uncertainty could be used rhetorically to justify urgency or fatalism; GShips will present it as a reason for reversible research, updated evidence, alternatives, and explicit wait or do-not-launch gates.

   What Would Change

   Long-baseline monitoring of nearby terrestrial planets could bound atmosphere and climate variability, while validated evolutionary models and a precursor in the target system could reduce interpretation risk. Evidence of stable conditions would narrow physical-change risk but not eliminate discovery risk, communication delay, or the possibility that life or hazards were previously missed.

   International legitimacy for settling or biologically seeding a world with credible indigenous life is unresolved.

   Rationale

   The Outer Space Treaty assigns state responsibility, due regard, consultation, and harmful-contamination duties, while COSPAR supplies scientific contamination policy for Solar System missions. Neither source creates a legitimate international authorization process for settling or intentionally seeding an extrasolar world with credible indigenous life; future-generation principles add interests but not a decision authority.

   Conflicts

   1. A generation-ship organization could gain influence from defining legitimacy rules; any framework must therefore be independently governed, internationally participatory, scientifically revisable, and able to deny or revoke a mission.

   What Would Change

   A widely ratified instrument or comparably legitimate international process would need to define representation, evidence thresholds, indigenous-life presumptions, contamination and noninterference duties, future-generation standing, enforcement, review, liability, and irreversible no-go decisions. A sponsor or launch state acting alone would not resolve legitimacy.

   1. GShips Project editorial synthesis

   Conflicts

   1. Earth-benefit language can be used to overjustify remote science or a future venture; GShips will distinguish intrinsic knowledge value, demonstrated methodological transfer, and speculative downstream applications.

   What Would Change

   Traceable cases in which exoplanet observations or models materially improve an Earth-climate, atmosphere, geology, or biosignature inference would strengthen the applied benefit. Failed transfer, incompatible regimes, or no measurable improvement would narrow the claim while leaving the basic scientific value intact.

    Rationale

    Planetary-protection programs already use contamination control, bioburden knowledge, cleanliness, documentation, trajectory analysis, and sample-return safeguards to protect scientific integrity and Earth's biosphere. Broader biosafety transfer is plausible and partly embedded in these practices, but it is not a substitute for clinical, laboratory, public-health, or biosecurity regulation.

    Conflicts

    1. GShips may develop contamination and evidence-assurance tools; this record authorizes no biological sampling, release, synthesis, clinical use, or biosecurity work and implies no NASA, COSPAR, or UN affiliation.

    What Would Change

    Comparative incident, audit, and validation evidence must show which planetary-protection practices improve a named biosafety or contamination-control outcome and where transfer fails. Laboratory, medical, environmental, and security authorities would still need to approve their own controls; misuse or overclaiming would narrow the benefit.

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.
