Questions and exclusions

Required questions

Required question 1 (exact ID: question-1)
Do the declared formulas or projection rules, constants, units, rounding, defaults, and invalid-state behavior match the shipped implementation?
Required question 2 (exact ID: question-2)
Are the guardrails and exclusions strong enough to prevent a teaching result from being mistaken for feasibility, safety, clinical, demographic, or mission evidence?
Required question 3 (exact ID: question-3)
Does the no-JavaScript presentation convey the same documented example, result, evidence boundary, and access to the underlying records?

Explicit exclusions

Structural or arithmetic correctness does not establish physical, clinical, ecological, demographic, or mission validity.
A teaching interface is not a design tool, safety case, population policy, or authorization to act.

Requested controlled scopes: accessibility-disability-justice, systems-engineering, visual-science-communication

Frozen-evidence decision window: 365 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.

Invalid Input Behavior
Reject out-of-range or nonnumeric values, preserve the last valid table, and perform no calculation.
Guardrails
Each value has an independent declared normalization boundary.
The output is an arithmetic gap in percentage points, not a closure estimate.
Explicit Exclusions
coupled water, carbon, nitrogen, oxygen, food, and waste balances
trace contaminants and stored inventory
time dynamics and microbiomes
maintenance and crew health
No Java Script Fallback

Linked records—not review targets here

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

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.

Download the six kit files below. Complete a copy of the JSON template offline and preserve its templateFingerprint.
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.
Validate the packet and completed copy.
```
node check-review-decisions.mjs \
  --packet PACKET.json \
  --decision COMPLETED.json
```
Add another --decision for each independent reviewer.
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.

Completion criteria

Every primary record must receive the required number of valid, current-fingerprint approvals; every complementary scope group and required domain must be covered; any unresolved revise, contest, or reject disposition blocks publication.

Named medical, reproductive, nuclear, radiation, cybersecurity, governance, and dual-use conclusions require two distinct qualified independent humans covering complementary domain-method and rights/public-interest scopes.

Reviewer identity, qualification, independence, conflicts, and compensation must be assessed by accountable human governance; local validation can only report structural validity.
Approve, revise, contest, reject, and recuse remain visible. A negative finding cannot be hidden by an aggregate approval percentage.
Revision creates a new record and packet fingerprint. Prior approvals do not carry forward automatically.
AI may assist with clerical comparison but cannot count as an independent reviewer, identity attestor, appeal authority, or second person.
