[Unreleased]

🏗️ Engine v2.3.0 — ds-stream Pipeline v4 — 2026-03-11

• ChecksumCodec — CRC32 integrity: append on encode, verify+strip on decode, Error on mismatch

• TagCodec — Attach channel ID for mux routing, drop wrong-channel frames on decode
• Pipeline::chain() — Compose two pipelines into one
• Pipeline::describe() — Human-readable dump (dedup → compress → encrypt)
