Implements AZ-297 InferenceRuntime's thermal_state() side: a singleton background-thread publisher that polls jtop (preferred) or pynvml (fallback) at config.thermal_poll_hz, stores an atomic ThermalState snapshot, and emits c7.thermal_transition FDR records on every throttle flip with a WARN log on entry and an INFO log on exit. Default-safe on TelemetryUnavailableError per Invariant I-6 with a 1-Hz rate-limited WARN. Sources return a raw ThermalReading; the publisher stamps measured_at_ns via its injected Clock so _JtopSource / _PynvmlSource stay clean of direct time.* calls (Invariant 2). _poll_once is the deterministic test seam — start() spawns the production thread. - c7.thermal_transition registered in fdr_client.records KNOWN_PAYLOAD_KEYS - [telemetry] optional dep group (jetson-stats, pynvml) added to pyproject - 14 unit tests (AC-1..AC-6, AC-8, NFR-default-safe, structural) green; AC-7 / AC-1 microbench / NFR-perf-poll Tier-2 deferred - full unit suite: 1140 passed, 11 expected Tier-2/CUDA skips Co-authored-by: Cursor <cursoragent@cursor.com>
