The tracked repo-pre-7 baseline is an exact snapshot of repo-pre-6 at the execution-start commit. The identities above were read from Git objects at that commit, not inferred from the live worktree.

Uncommitted changes were already present in repo-pre-7/src/internal.h and repo-pre-7/src/inode.c when this document was written. This baseline does not assess, validate, or claim completion of those changes.

Exact Source Scope

Pre7 contains exactly two source tasks:

1. Rename the private inode-location helper from erofs_nid_to_offset() to erofs_iloc() in repo-pre-7/src/internal.h and repo-pre-7/src/inode.c. This is an identifier-only alignment; the FreeBSD signature, implementation, callers, metabox handling, overflow checks, and failure behavior remain unchanged.
2. Extract the private erofs_xattr_prefix() mapping helper from erofs_xattr_namespace_prefix() in repo-pre-7/src/xattr.c. The existing wrapper retains FreeBSD namespace validation, namespace matching, errno selection, and all existing get/list call sites.

No other source file, helper cleanup, behavior change, public interface change, formatting pass, or deferred planning item belongs in Pre7.

Validation Status

Per the current execution instruction, this baseline-recording step performs no build or test activity. Historical Pre6 evidence is not a Pre7 result.

Validation item	Status
Pre7 source implementation validation	NOT RUN
Static reference and behavior-matrix checks	NOT RUN
Independent source-commit revert checks	NOT RUN
WITH_ZSTDIO=0 build	NOT RUN
QEMU smoke testing	NOT RUN
Manual or automated runtime tests	NOT RUN
CI testing	SKIPPED

This is an implementation baseline only. It is not a completion report and does not claim that either Pre7 source task is complete or correct.
