  * Android microbenchmark for all secp256k1 operations used by Nostr.
  *
- * Uses AndroidX Benchmark (Jetpack Microbenchmark) for accurate, warmed-up
- * measurements on real Android hardware. Results appear in Android Studio's
- * benchmark output with ns/op, allocations, and percentiles.
+ * Measures the same operations as the JVM benchmark (Secp256k1Benchmark.kt) and the
+ * K/Native benchmark (Secp256k1NativeBenchmark.kt) for cross-platform comparability.
  *
  * Tests are structured as matched pairs: "Foo" uses the native C library (ACINQ/JNI),
- * "FooOurs" uses the pure-Kotlin implementation. This allows direct comparison of
- * each operation between native and Kotlin on the same device.
+ * "FooOurs" uses the pure-Kotlin implementation.
  *
  * NOTE: verifySchnorr uses the same pubkey repeatedly, so it benefits from the
  * pubkey decompression cache and P-table cache. This is realistic for Nostr
  * (feed from one author) but not representative of first-time verification.
  *
- * Test data is the same across all 3 platform benchmarks (JVM, Android, K/Native)
- * for cross-platform comparability.
+ * Test data is the same across all 3 platform benchmarks for cross-platform comparability.
