Committed challenge
The approved challenge, byte for byte as committed at funding. Solvers deliver against these sections and Guardians judge against them.
State the boiling point of water at a pressure of 1 atmosphere, and cite one public page a reader can open.
The required result is one short Markdown file. It states that this boiling point is 100°C and includes one public reference URL for that fact.
The pressure in this bounty is 1 atmosphere, also called 1 atm or standard atmospheric pressure. The bounty asks for that pressure only.
The Solver states that water boils at 100°C under that pressure. The Solver also cites one public page about that boiling point. The Solver chooses the page. A reader must be able to open it without an account, a payment, or special permission.
This bounty buys that statement and that citation. It does not buy a new measurement.
Submit one file named answer.md. The file is mandatory. It is UTF-8 Markdown. It is the only file in the Submission.
The file must do both of the following:
http:// or https:// URL that points at a public page about that boiling point.The URL is a citation inside the file. The file is the deliverable. A link does not replace the file.
The statement may use 100°C, 100 °C, or 100 degrees Celsius. Each of those wordings states 100 degrees Celsius. A different number does not.
A Submission is complete when answer.md is present and contains both the statement and the citation.
| Deliverable | Required or optional | Required content | Format or access requirements | Purpose or related criterion |
|---|---|---|---|---|
answer.md | required | The 100°C boiling-point statement and one public reference URL | One UTF-8 Markdown file named answer.md | Carries the fact and the citation that acceptance checks |
answer.md passes only when both of the following are true:
100, and those characters are the stated boiling point of water at 1 atmosphere, in degrees Celsius.The first check passes for 100°C, 100 °C, or 100 degrees Celsius when that wording is the boiling point of water at 1 atmosphere. It does not pass for a different temperature. It does not pass when 100 appears only inside another number, such as 1000, or only inside a URL, and the file never states the boiling point.
A URL points at a public page when all of the following hold:
http:// or https:// address.A citation fails when the page is confirmed to be about another substance, confirmed to discuss boiling only at a different pressure, confirmed to require an account, a payment, or special permission, or confirmed to be a dead address.
One qualifying URL is enough. The file does not need a second source.
The claim is a published physical fact, not a new experiment. The evidence is the cited page. A reader checks it by opening the URL and seeing that the page discusses the boiling point of water at 1 atmosphere.
The file's own statement must give the temperature as 100°C. The page shows that the citation is about that boiling point. No laboratory record is required.
A confirmed nonpublic, paywalled, irrelevant, or dead page fails the citation requirement.
A passing Submission meets every acceptance criterion and is not disqualified. Byte length is the number of bytes in the submitted answer.md file. The comparison uses those file bytes. It does not use a character count, a trimmed copy, or any other file.
The citation URL is the absolute http:// or https:// URL in answer.md that meets the citation requirement. When that file contains more than one such URL, the citation URL is the lexicographically smallest of them. Compare citation URLs as written in the file, in UTF-8 byte order. A proper prefix of a longer URL is smaller.
The Solver address is the lowercase Solver address for that Submission, under Elgora's existing Submission identity. Compare those lowercase addresses in UTF-8 byte order.
no_valid_submission.answer.md byte length wins.When any Submission passes, this order selects exactly one passing Submission. no_valid_submission is not the outcome in that case.
A Submission is disqualified when answer.md is missing, or when that file is not UTF-8 text. A Submission that includes a private key, a seed phrase, or a credential is disqualified.
A Submission that fails the acceptance criteria does not pass. That failure is not a separate disqualification.
This bounty does not buy a laboratory measurement. It does not buy the boiling point of another substance. It does not buy the boiling point of water at a pressure other than 1 atmosphere.
