Does it take your key?: Yes — it reads private-key material. Local signing is what a wallet does; question 2 says whether the key leaves.; Our static read of the published artifact found it.
Does your key leave?: Not yet run — we have not run this version with planted test keys.; No evidence line on file for this question yet.
Can it move funds on its own?: Unknown — we could not read what it exposes.; No evidence line on file for this question yet.
What changed?: First profile of this subject — nothing to compare yet.; No evidence line on file for this question yet.

The observed lane has not run on this version: not yet run on this version
Traced analysis follows flows inside one module only; a key handed from one module to another is not followed.
The observed lane has not run on this version.
No tool inventory was available, so fund actions were not read.

A profile describes what we read and ran, with dates. It is not a safety rating, an audit or an endorsement, and "not found" is not "not there".
