# Batch 001 Addendum 001 — Security-Sector Retrieval via Patched 0xE7 Memdump

## New Knowledge Preserved

A fleet GDR-8163B is cross-flashed with GDR-8050L firmware and patched to allow `0xE7` memory dumps.

The user has not yet attempted to retrieve Xbox security-sector data through this path.

## Classification

- type: open experimental avenue
- trust: hardware configuration reported by operator
- validation state: untested
- PFES disposition: preserve as an explicit backlog item and future acquisition experiment

## Retention Requirement

Do not let this avenue disappear during unlocker, FriiDump, analyzer, or emulator refactoring. Any future test must preserve patch provenance, firmware identity, disc state, memory ranges, and command transcript.
