Findings

clean

identical on amd64, arm64 — one table describes both

No known findings in this image at the last scan.

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

Composition

default + git
runtime php
composes php, git

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.

none

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.
