Lesson 3.5
Break it live - five ways framing fails
Reproduce the real framing failures with your own hands (the dropped fragment, the quadratic rescan, the swallowed request, the mangled multibyte body, the trusted content-length), then watch the same request whole and byte-by-byte produce one identical response while the stage checks stay green.
What you will build
- Reproduce each framing failure on a throwaway copy and read it on the wire before undoing it.
- Demonstrate that a request sent whole and one byte per segment produces one identical response.
- Run the stage-03 and stage-04 checks and the full regression through stage 04.
