maps(com.tranzmate): record signer_sha256 from device - #67
Merged
Conversation
Read off the installed base APK via apksigner (single signing cert, no rotation). Same cert across both published version_codes. Verified with the schema + semantic validators locally.

signer_sha256: c42f9060274bc622dd53d1ac25dc1c0167c3023ec3d87649c3c9ec10e3ad7db0to both publishedcom.tranzmatemaps (1785.json,1789.json), which previously recorded no signing cert.Why
The maps carried no
signer_sha256, so clients had no version-guard against applying them to the wrong app build. The value was read off the installed base APK withapksigner verify --print-certs(single signing certificate, no key rotation), which is exactly the canonical colon-free lowercase-hex form the field requires. The signing cert is the same for both version_codes.Testing
