 **Goal:** Every Javadoc block should add information you cannot glean from the method signature alone. Anything else is
 noise and slows readers down.

 | State *behavioural contracts*, edge-cases, thread-safety guarantees, units, performance characteristics and checked exceptions. | Restate the obvious ("Gets the value", "Sets the name"). |
 | Keep the first sentence short; it becomes the summary line in aggregated docs. | Duplicate parameter names/ types unless more explanation is needed. |
-| Prefer `@param` for *constraints* and `@throws` for *conditions*, following Oracle’s style guide. | Pad comments to reach a line-length target. |

 The principle that Javadoc should only explain what is *not* manifest from the signature is well-established in the
