Functions
void	GstHwPathTelemetry::recordMapFailure (HwVideoBufferPath path) noexcept
	mapTextures() returned an invalid bundle (GPU import failed).
quint64	GstHwPathTelemetry::takeMapFailureCount (HwVideoBufferPath path) noexcept
quint64	GstHwPathTelemetry::peekMapFailureCount (HwVideoBufferPath path) noexcept
void	GstHwPathTelemetry::recordTextureReuse (HwVideoBufferPath path) noexcept
	Prior frame's QRhiTexture wrappers reused (decoder pool returned same native handle).
quint64	GstHwPathTelemetry::takeTextureReuseHits (HwVideoBufferPath path) noexcept
void	GstHwPathTelemetry::recordSyncWait (HwVideoBufferPath path, bool gpuSide) noexcept
	GL fence sync wait; split CPU-blocking vs GPU-side.
quint64	GstHwPathTelemetry::takeSyncWaitCounts (HwVideoBufferPath path, quint64 &gpuWaits) noexcept
	Reads-and-resets CPU waits; writes GPU waits into gpuWaits.
void	GstHwPathTelemetry::recordImageCacheHit (HwVideoBufferPath path) noexcept
	Native image/texture cache hit/miss accounting.
void	GstHwPathTelemetry::recordImageCacheMiss (HwVideoBufferPath path) noexcept
quint64	GstHwPathTelemetry::takeImageCacheHits (HwVideoBufferPath path) noexcept
quint64	GstHwPathTelemetry::takeImageCacheMisses (HwVideoBufferPath path) noexcept
void	GstHwPathTelemetry::recordDelivered (HwVideoBufferPath path) noexcept
	Frames successfully delivered via this path.
quint64	GstHwPathTelemetry::peekDeliveredCount (HwVideoBufferPath path) noexcept
quint64	GstHwPathTelemetry::takeDeliveredCount (HwVideoBufferPath path) noexcept
void	GstHwPathTelemetry::recordMapDuration (HwVideoBufferPath path, qint64 nsecs) noexcept
	Per-path mapTextures() wall-time, fed into an EWMA; peek returns the smoothed value in microseconds.
quint64	GstHwPathTelemetry::peekMapDurationUsEwma (HwVideoBufferPath path) noexcept
void	GstHwPathTelemetry::recordFenceTimeout (HwVideoBufferPath path) noexcept
	DMABuf EGL fence wait timed out (GPU stall) and fell through to the mmap barrier.
quint64	GstHwPathTelemetry::peekFenceTimeouts (HwVideoBufferPath path) noexcept
quint64	GstHwPathTelemetry::takeFenceTimeouts (HwVideoBufferPath path) noexcept
void	GstHwPathTelemetry::recordMmapBarrierHit (HwVideoBufferPath path) noexcept
	DMABuf mmap CPU-side completion barrier taken (no usable fence ext).
quint64	GstHwPathTelemetry::peekMmapBarrierHits (HwVideoBufferPath path) noexcept
quint64	GstHwPathTelemetry::takeMmapBarrierHits (HwVideoBufferPath path) noexcept
void	GstHwPathTelemetry::recordExplicitFenceWait (HwVideoBufferPath path) noexcept
	DMABuf imported the producer's dma-buf/native fence and did a GPU-side wait (skipped the mmap barrier).
quint64	GstHwPathTelemetry::takeExplicitFenceWaits (HwVideoBufferPath path) noexcept
void	GstHwPathTelemetry::recordFallbackReason (HwVideoBufferPath attemptedPath, HwFallbackReason reason) noexcept
	Per-(path,reason) fallback accounting; lets a bug report show why a path demoted to CPU.
quint64	GstHwPathTelemetry::peekFallbackReason (HwVideoBufferPath attemptedPath, HwFallbackReason reason) noexcept
quint64	GstHwPathTelemetry::takeFallbackReason (HwVideoBufferPath attemptedPath, HwFallbackReason reason) noexcept
void	GstHwPathTelemetry::recordStreamDemotion (HwVideoBufferPath negotiated) noexcept
	One-shot-per-epoch event: a stream that negotiated a HW path demoted to CPU. Distinct from per-frame CPU counts.
quint64	GstHwPathTelemetry::takeStreamDemotions (HwVideoBufferPath negotiated) noexcept
