# XGD1 geometry and drive-captured lead-in evidence

This directory contains the compact, repository-appropriate evidence retained
from the FriiDump 0.5.3.11 through 0.5.3.14 investigation.

Retained:

- the 13 cache-aligned physical-sector geometry samples;
- the consolidated machine-readable closure record;
- the completed 0.5.3.14 full-output and Redump comparison summary;
- a path-sanitized media/layout evidence record.

Not retained:

- local build logs;
- runner transcripts;
- package checksum rehearsals;
- duplicate stdout/stderr captures;
- full logical-sector byte dumps;
- the 7.29 GiB ISO;
- PFI, DMI, AD C0, or other disc-specific binary payloads.

Evidence conclusion:

- unlocked source LBA `0..31` is real drive-readable content and maps to
  full-output LBA `198144..198175`;
- unlocked source LBA `32` begins XDVDFS at output LBA `198176`;
- pregame and postgame physical geometry is resolved;
- inaccessible pregame and postgame contents remain unresolved zero-filled
  placeholders;
- no exact Microsoft Xbox DAT identity was established.
