Check 8d still locked the matcher to the pre-#963 'Grep|Glob' and failed
the pr-smoke leg on all platforms. The matcher now includes Read (the
augmenter injects the coverage note when a not-fully-indexed file is
read; structurally non-blocking, so the issue-#362 gate hazard cannot
recur). The guard now pins the exact new matcher and still rejects
Search/catch-all creep.
