Problem

A regression reproduced from public bug-fix history causes a visible test to fail on the parent snapshot.

Root cause

Written by you, in your own words, after tracing the failing test into the runtime source. (Filled in from your submission — not provided here.)

Fix summary

A minimal patch that makes the visible regression test pass without breaking neighbouring behaviour.

Resume-safe summary

Completed an OSS-backed Buglyst debugging lab based on public bug-fix history: reproduced a failing test, traced the root cause, and shipped a minimal patch that passed visible and hidden validation. Not an upstream contribution.
