Phase-0.7 rollback preparation

Status: OFFLINE PREPARED; NOT DEPLOYED.

The stock elfldr v0.23 release asset is included when the offline package is generated:

• size: 397000 bytes;
• SHA-256: 092d16ee0ede0c494947efd38d1a17bbd7cc4b022d3858ea898833c188c703e8.

The exact stock Payload Manager v0.3.1 binary is not present in the offline workspace. Its previously verified installed/release identity is:

• size: 2050320 bytes;
• SHA-256: 518740adbacccb9094fadb07dd424c53ee290f38306449ccc9d6957fdf813c0b.

Therefore any later installation must first make a byte-for-byte backup of the actual installed Payload Manager and verify that exact hash. If it differs, stop. The rollback set is not complete until that on-device backup exists.

Rollback authorization is separate from installation authorization. This document intentionally contains no connection, copy, service-start, or execution command.
