chore(core): update T3W1 dev secmon
[no changelog]
What changed, and why it matters
This commit replaces two precompiled binary files used for the T3W1 hardware model's secure monitor in development builds. The actual code changes cannot be seen because the files are binary blobs. There is no description of any security fix or vulnerability, and no independent references were provided.
Treat as opaque firmware update. If reviewing for security, request the corresponding source commit, build reproducibility artifacts, or vendor release notes for the secure monitor. Without those, no security classification is possible.
Security signals we found
Binary-only update to security-critical component (secure monitor)
No source diff or changelog explaining the change
No vendor statement of security relevance
No CVE, advisory, or researcher attribution in commit or references
Evidence from the diff
The commit updates secmon_DEV.bin and secmon_api_DEV.o under core/embed/models/T3W1/secmon/. These are binary artifacts for the T3W1 secure monitor (development variant). The diff only shows that the binaries differ; no source code, symbols, or changelog details are available. The title calls it a chore and explicitly marks it [no changelog].
