feat(protob): extend ApplySettings
- add auto_lock_delay_battery_ms to set delay in ms after which the
device locks when on battery or wireless charger
[no changelog]
✓ Descriptive subject✓ Uses a recognizable type or scope✓ Provides detailed explanatory context
What changed, and why it matters
This commit adds a new device setting called auto_lock_delay_battery_ms to the Trezor protocol definitions. It lets users configure how long the device waits before automatically locking when running on battery or a wireless charger. The change only updates generated message bindings across Python, Rust, and core firmware; it does not contain any actual lock behavior logic or security fix.
Recommended action
No immediate security action is required for this commit. When the corresponding firmware logic is later implemented, review it for proper bounds validation, safe defaults, and user confirmation before the setting takes effect.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The patch extends the ApplySettings protobuf message with an optional uint32 field auto_lock_delay_battery_ms (field number 15) and regenerates the corresponding bindings in core/src/trezor/messages.py, python/src/trezorlib/messages.py, and rust/trezor-client/src/protos/generated/messages_management.rs. No firmware logic consuming this field is present in the diff, and no validation, bounds checking, or security behavior is shown.
