The five _resolved_api_call_stale_timeout_base integration tests reloaded
hermes_cli.config + hermes_cli.timeouts via importlib.reload to clear cached
config. Under xdist that mutates module-global state shared across the worker
process, so a sibling test could leave the config cache in a state that made
get_provider_stale_timeout return a leaked value — intermittently failing
test_reasoning_floor_applies_to_opus_4_thinking (shard 6 flake, #52217 area).
Patch run_agent.get_provider_stale_timeout per-test instead: floor-path tests
get None (resolver falls through to the reasoning floor / env var / default),
the explicit-config test gets 60.0 (priority-1 short-circuit). Same assertions,
no shared-module mutation, deterministic under parallel execution.
Wire get_reasoning_stale_timeout_floor() into both stale detectors so known
reasoning models (Nemotron 3 Ultra, OpenAI o1/o3, Opus 4.x thinking, DeepSeek
R1, Qwen QwQ, Grok reasoning) tolerate multi-minute thinking phases instead of
the upstream gateway idle-killing the socket (BrokenPipeError) before first
token. Applied as max(default, floor) — never overrides explicit user config,
never lowers an existing threshold.
The reasoning_timeouts.py allowlist module already landed on main via #52795,
so this salvage carries only the wiring + tests (the duplicate module and the
stale-base MoA reverts from the original PR branch are dropped).
Salvaged from #52238. Fixes#52217.
