| ## 2023-10-27 - Terminal Search Hot Loop Case Folding | |||
There was a problem hiding this comment.
Remove this automation note or keep any lasting rationale beside the owning search code/tests. As added, .jules/ is a new top-level directory containing only a task-specific learning record, with no build or contributor workflow consuming it, so it violates the repository contract that new root categories be durable and feature-specific material stay near its owner.

Add an Unreleased changelog entry for this optimization. For users searching large scrollbacks, the new fast path intentionally changes visible search responsiveness—the commit reports roughly halving a missed-query scan—but the patch leaves CHANGELOG.md unchanged, so this release-facing improvement will not be documented.

Since the vast majority of terminal content and search queries are ASCII, we can precalculate the ASCII lower and upper bounds outside the hot loop to short-circuit the vast majority of non-matches without a function call overhead.test_perf_real_world3.rsthat validates performance in ASCII text streams.PR created automatically by Jules for task 10144745834436658151 started by @Lucenx9
