@@ -82,6 +83,8 @@ Recent decisions affecting current work:
 - [Phase 02]: int16 conversion uses float * 32767 to avoid positive overflow at exactly +1.0
 - [Phase 02]: RunSynthesis takes snapshot slice (not channel) enabling zero-packet guard before file creation
 - [Phase 02]: EncodeMP3 and RunSynthesis are separate functions for independent testability
+- [Phase 03-01]: hashBucket uses (dstPort*31 + protoNum*7) % 4 for deterministic 4-bucket unknown class assignment
+- [Phase 03-01]: TestHashBucketDistribution uses minimal custom rules (not DefaultRules) because DefaultRules catch-all OtherTCP/OtherUDP prevent hashBucket from being reached
