How an answer becomes verified
The useful answer is not the fastest guess. It is a reproducible procedure tied to a primary source and checked against known cases.
Evidence labels
| Label | What it means here | Can it produce a solver answer? |
|---|---|---|
| Observed | Directly checked in a named primary source or repeatable first-hand test. | Only after procedure tests also pass. |
| User-provided | A note entered by the player in this browser session. | No. |
| Hypothesis | A possible interpretation that still needs a controlled test. | No. |
| Unknown | Required evidence is unavailable or ambiguous. | No. |
Publication gate
- Name the module without relying on a search suggestion alone.
- Record a primary source URL, title, and retrieval date.
- Translate the rule into a deterministic input and output contract.
- Add normal, boundary, and failure cases.
- Publish only when the same inputs reproduce the same result.

A module appears in this registry only while its release evidence, deterministic contract, and regression tests remain current. A missing answer is safer than a confident but fabricated instruction during a timed session.
