pp-regex-compile-in-loop — removed

Status

removed. The microbench below is historical. See pp-regex-compile-in-loop.REMOVED.md. The slug is not reused. The 2026-10-22 corpus verdict does not cover this slug.

Measurement

5000 searches of a fixed string. Before re.compile each iteration; after compiles once. On this small pattern the search dominates the compile.

The microbench shows a small difference only. Default stays hint.

Unblock

Do not set the default to error from this file alone. A changing input, a cold path, or another ABI can erase the difference. Corpus triage is still required before any default change.
