Add 50k/100k/250k-element size cases (~195 KB–954 KB packets) to the DS and
hub size axes so the stress suite exercises UDPSClient multi-fragment
reassembly under load, and lift the now-outdated 64 KB validation cap to the
1 MiB deliverable cap (UDPS_CLIENT_MAX_PACKET_BYTES). Slowed producers keep
bandwidth realistic.

Full-chain orchestrator (run_chain_e2e.sh) now runs the starter set green
(3 pass). Fixes found bringing the chain up end-to-end:
- client: gorilla/websocket cannot survive a read deadline (next ReadMessage
panics "repeated read on failed connection"); replace the poll-with-deadline
loop with a background reader goroutine + mutex-guarded state.
- orchestrator: guard env.sh's unbound LD_LIBRARY_PATH under set -u.
- scenarios/gen_data: centralize NUM_ROWS/ROW_DT and enforce sine freq to be a
multiple of the buffer fundamental (LOOP_HZ=5 Hz) so the looped FileReader
buffer is a seamless waveform; align starter freqs (5/5/10 Hz).
- gen_cfg: FileReader allows exactly one consuming Function, so route tapped
(oracle=fed/both) sources through the DDB (ReaderGAM->DDB, then StreamGAM and
TapGAM both read DDB) instead of a second FileReader consumer.
- validate_waveform: fidelity gates correctness (bit-exact / within one quant
level); sine shape becomes a gross frequency-sanity gate (corr>=0.5) plus a
tracked corr/nRMSE quality metric, since per-sample wall-clock calibration
(Phase-A) and FULL_ARRAY packed timestamps (Phase-A4) are still pending.

End-to-end test streaming three float32 signals via a MARTe2 UDPStreamer
app into a standalone StreamHub with the recorder enabled, then validating
the recorded FileWriter-compatible .bin against the streamed input with
validate_binary.py. All recorded rows are byte-identical to input rows.

Add a FileWriter-compatible per-source binary recorder: native-type encode
and TypeDescriptor mapping, FileWriter header serialization, subset/quantized/
ACCUMULATE row serialization, and push-thread double-buffer flush with size-cap
rotation, keep-N pruning, fdatasync cadence, disk-free and staging-overflow
guards. Covered by 12 GTests; full suite (83) green.
