test(scripts): add E2E AI chat + sandbox code-path benchmarks
bench-ai.py drives the /ai chat path end-to-end (SRP -> Fernet -> WebSocket -> provider), measuring TTFT/total/tok-s per model, with a --direct provider mode that isolates raw model throughput from event-loop contention. bench-sandbox.py benchmarks the /ai <agent> !<task> sandbox code path by playing the room owner on the zero-knowledge relay: it grants drive, sends graded tasks (L0 no-grant refusal, file/script/logic/multistep, destructive gating+confirm, blast-radius cap), captures the agent's injected _sbx:input frames, and grades correctness behind the same destructive guard. Includes REPL-aware exec replay (folds python3 sessions into heredocs), prompt-prefix stripping, model-fail vs replay-limit tagging, --runs N averaging with per-step timing, and auto-bumped timeouts for reasoning models.

"""bench-ai.py — end-to-end latency/throughput benchmark for the /ai agent.
|
||||
|
||||
Stands up the real relay server, summons each model as a real agent that joins
|
||||
the encrypted room, then sends a fixed prompt as an ordinary user and measures
|
||||
the round trip the way a teammate actually experiences it:
|
||||
|
||||
TTFT time to the agent's first streamed token (perceived latency on CPU)
|
||||
total time to the final, persisted reply
|
||||
gen total - TTFT (decode time)
|
||||
tok/s estimated reply tokens / gen (~4 chars/token)
|
||||
|
||||
Everything travels the real path: SRP auth -> Fernet -> WebSocket -> provider.
|
||||
Nothing is mocked. Run from the repo root with the project venv:
|
||||
|
||||
.venv/bin/python hh/scripts/bench-ai.py \
|
||||
--models llama3.2:3b qwen2.5:3b granite3.1-dense:2b
|
||||
|
||||
Useful flags: --prompt, --num-thread, --num-ctx, --timeout, --runs, --port.
