 * cognium-dev #239 C.2 — weak-crypto test-file allowlist.
 *
 * Test-file layouts vary across languages/build systems (Maven/Gradle,
 * Python pytest, Go, JS/TS jest+vitest, RSpec). This module owns the
 * zero-dependency regex-only classifier used by passes that want to
 * allowlist findings on test fixtures.
 *
 * Browser + Node.js compatible: no glob library, no `path` module.

/**
 * Returns true if the given filepath looks like a test / spec file.
 *
 * Callers that want to allowlist crypto / secret / RNG findings on
 * KAT / reproducibility vectors should short-circuit their pass when
 * this predicate fires.
 *
 * `filepath` is expected to be the `graph.ir.meta.file` string
 * (repository-relative or absolute). Backslashes are normalised.
 *
 * JVM-family files (`.java` / `.kt` / `.scala` / `.groovy`) require
 * both a test-dir match AND a JUnit-style filename suffix
 * (`*Test|*Tests|*Spec|*IT|*ITCase|*TestCase`). Maven's
 * `src/test/java/**` layout hosts vulnerability fixtures and demo
 * corpora alongside real unit tests; the filename convention is the
 * only reliable signal.
