Obtain/Recover Exact ~330 LOC Repro File for Residual #14

[hyperpolymath]

Goal: Obtain or confirm unrecoverability of the original ~330 LOC file referenced in issue #38 for accurate historical forensics and performance comparisons.

Tasks:

• Search all local and cloud backups, related email threads, shared drives, and dev machines for the missing file or any variants.
• If recovered, attach the file directly to this issue for archival and detailed regression checking.
• If confirmed missing, document all search attempts and attach the faithful reconstruction already present at crates/my-lang/tests/fixtures/issue_14_scaffold.my for reference and close this sub-issue as 'unrecoverable'.

Definition of Done:

• File attached, or search and outcome documented.
• Clear linkage with parent issue context.
