A player was marked wrong for a right answer. The question was:

Which term is this example about?
An app asks ▁▁▁ for database credentials at start-up and gets a user that expires in an hour.

The options were gVisor, OpenBao, Vault and cert-manager. The example is from Vault's card, but the glossary itself says OpenBao is Vault's API-compatible fork (openbao fork-of vault), so OpenBao was just as right.

Cause

Wrong answers were picked from similar terms, excluding only terms that share a name or distinguish each other. With the name blanked out, an example or a summary can fit a fork, an alternative or a managed version of the answer as well as the answer itself.

Fix

Questions that show a text and ask for the term ("this example", "described here") no longer offer as a wrong answer any term the glossary links to the right one, by any edge. "What is X?" questions are unchanged, since each option there is a summary that describes only its own term.

Tests

  • TestEveryQuestion now checks the rule across every term. With the new condition switched off, it finds 466 such questions across its seeds, including Argo CD as a wrong answer to an example of Flux.
  • TestNoLinkedWrongAnswers covers the reported case.
  • With the fix, all tests pass, including those against PostgreSQL.

A daily round already dealt keeps its stored questions. The fix applies to rounds dealt after this is deployed.

This change was first pushed to #21 after it had been merged, so it never reached dev.

A player answered OpenBao to "An app asks ▁▁▁ for database credentials at
start-up" and was marked wrong. The example is Vault's, but OpenBao is
Vault's API-compatible fork, so it was just as right.

With the name blanked out, an example or a summary can fit a fork, an
alternative or a managed version of the answer as well as the answer
itself. Questions of those two kinds now never offer a term the glossary
links to the answer, by any edge, as a wrong one. The test that builds
every question checks for it: before this, 466 of them across its seeds
offered a linked term, Argo CD for an example of Flux among them.
Definition questions are unchanged, since each summary describes only
its own term.
