ousast scan src/api
The container becomes an implementation detail. The engine is a JVM and ~2 GB
of Joern, and a contributor evaluating this tool should not have to install
either to try it -- what they get is a command.
Path rewriting is what makes it feel local: arguments under the working
directory are mapped to their mounted equivalents, so `src/api` means what the
user expects. Anything outside the mount is passed through unchanged WITH A
WARNING rather than silently rewritten into a path the container cannot see --
a wrong path that looks like it worked is worse than one that complains.
A native install wins when it is present. Someone who installed Joern
deliberately should not be quietly routed through a container, so the wrapper
uses a local joern-parse and venv when both exist; OUSAST_PREFER_NATIVE=0
forces the container. Verified end to end from an unrelated directory.
The image builds itself on first use and says why it is pausing. A first run
that prints a wall of build output and then works is worse than one that
explains itself.
Defaults stay conservative: the working directory mounts READ-ONLY, findings go
to ./.ousast as the only writable mount, and the network is off unless
`ousast-with-judge` asks for it.
