Extend replay to streaming reads, count/byte limits, compression, fragmented responses, and read interruptions after SDK delivery. Fuzz bytes generate the workload and fault plan; replay checks the expected record prefix. Healthy responses pass through the proxy unchanged unless a transformation is requested.
Review
makeTrace, the reader/proxy delivery handshake, and framing changes. The fuzz coordinator owns Lite and shares its endpoint with workers, since workers can exit without cleanup; each trace still gets a fresh basin and stream.Validation: Harness race tests against real Lite, harness lint, and workflow validation passed. The sequential fuzzer and saved JSON trace replay passed.
Part 3/6 replacing #375. Depends on #378. Next: #380.
Reviewable now; kept as a draft until its predecessor lands. After that merge, rebase onto
main, retarget this PR tomain, and mark it ready.
