Findings

clean

identical on amd64 — one table describes both

No known findings in this image at the last scan.

These are the findings of cpanm, which ships every tool in this project. kapsl reports and gates; it never edits an image to clear a finding.

Composition

default + gcc, wget
runtime perl, curl, bash, posix-essential, make, tar, gzip
composes perl, curl, bash, posix-essential, make, tar, gzip, gcc, wget

Some tools are only useful composed: a pip-installed CLI needs python as its runtime, bash pulls in coreutils. kapsl resolves that for you — -e git,python:flake8 composes explicitly.

Sandbox boundary

cpanm

capabilities

netrw

Filled is granted to every invocation; the rest need --cap at the point of use.

seccomp tier

default

The syscall filter applied to this tool's entry point. Tools sharing an image do not share a tier.

per-subcommand

no overrides

Every invocation gets the same boundary. Where a tool needs more for one subcommand only, kapsl scopes it there rather than granting it everywhere.
