| # Proactively hunt narrow, runner-specific concurrency bugs (data races, | |
| # use-after-free, UB) that the PR-time cpp-tsan / cpp-sanitizer smokes only | |
| # catch by luck on a single pass. This runs the SAME smoke scripts but with | |
| # STRESS_MULTIPLIER cranked up, so the race window is hammered many times more | |
| # per night. On failure it files an issue with the full sanitizer report — | |
| # the diagnostic the PR smoke truncated/lost in earlier incidents (#96). | |
