From compression/cutils/quasar/:

quasar build

Prerequisites: Quasar CLI and Agave toolchain (see Quasar.toml).

This variant has no automated test suite yet: the instruction handlers CPI into external programs (Bubblegum, SPL Account Compression) and a QuasarSVM harness that loads those fixture binaries has not been written. quasar build verifies the program and CPI construction compile.

The Anchor twin at ../anchor/ has a full LiteSVM integration suite that exercises the same flows against mainnet-dumped fixture programs; use it as the behavioural reference.

Read src/ and Quasar.toml. Compare with the Anchor variant in the same example where present.
