quiet
Its install steps ran with decoy credentials in reach and touched nothing we watch.
Its install steps ran here, with decoy credentials in reach, and touched nothing we watch: no network, no credential files. That is evidence, not proof: code can wait for a different machine or run later, when it is used.
The trace shows what a step attempted. A quiet trace is evidence, not proof.
Install steps
@anthropic-ai/claude-code runs this install step of its own:
- postinstall

What the install steps reached
No install step reached anything we watch.
- Programs
- node

Dependencies
The dependency tree was installed.
the dependencies were not installed and their install steps were not run: @anthropic-ai/claude-code-linux-x64@2.1.316: larger than 96 MiB

- Level
- quiet
A comparison of the notary's signed records of both versions, made when this page is read; not part of either signature. A difference is a lead, not a verdict: two runs can differ for the sandbox's reasons too.
Sandbox
network=none; capabilities=all-dropped; rootfs=read-only; user=nobody; harness=separate-user
The kernel tracer attached every probe before the steps started and saw 199 events across 2 traced steps, with none lost.

What this does and does not say
The claim is about the bytes, not the name.
The signature covers these exact bytes. Another version is another check.
A quiet trace is evidence, not proof.
Code that only runs later, when your app calls it, is out of reach.
A signature is not an endorsement.
It says what happened, not that the code is good.
Twenty checks an hour for each network address. When a limit is ours, the record says unfinished and names it.
