Value normalisation

No core answer is documented.

Not covered: CAP validates on write and does not change what it stores. @assert.format will reject a value with a trailing space; nothing in the core removes it, so normalisation is a handler you write or a plugin you install.

An ABAP-era expectation more than a modern one — conversion exits did this, and people arriving from that world look for it. Both entries here are annotation-driven and by the same vendor, which is a thin base to call this settled.
