Progress on #13405, which asks for an explicit characterisation of the equivalence relation like the one given here. Also progress on #11895, because we're using the term "build trace entry" instead of "realisation". Mention #9259, a future work item.

# Appendix: Math notation

A few times in this manual, formal "proof trees" are used for [natural deduction](https://en.wikipedia.org/wiki/Natural_deduction)-style definition of various [relations](https://en.wikipedia.org/wiki/Relation_(mathematics)).

The following grammar and assignment of metavariables to syntactic categories is used in these sections.
|
|
|
|
\\begin{align}
|
|
s, t &\in \text{store-path} \\\\
|
|
o &\in \text{output-name} \\\\
|
|
i, p &\in \text{deriving-path} \\\\
|
|
d &\in \text{derivation}
|
|
\\end{align}
|
|
|
|
\\begin{align}
|
|
\text{deriving-path} \quad p &::= s \mid (p, o)
|
|
\\end{align}
