Expand description
What a release lands, read as data rather than compiled in.
A release declares its own projection in instance/projection.toml.
The engine reads the declaration of whichever release it was asked
about, so a plan toward an older release lands exactly that release’s
set. While the projection lived in Rust constants, the only witness of
what a release landed was that release’s own binary, and a plan toward
an intermediate version could only ever be an approximation.
Parsing lives here, in the domain, rather than on the bundle boundary. The boundary answers with bytes; what those bytes mean is this layer’s business, and a transport that understood the projection would be a second place to change when the projection grows.
