  "message": "DualPi2: Implement WRR credit scheduler\n\nImplements the RFC 9332 / Linux sch_dualpi2 byte-weighted round-robin\n(WRR) credit scheduler (Config::c_protection, defaulting to 10% weight\nfor the classic queue and 90% weight for the L4S queue):\n\n1. Prevents classic queue starvation: Previously, l4s_queue_ had strict\n   priority over classic_queue_, allowing sustained L4S traffic to\n   starve non-ECT packets (such as ICE STUN pings) in classic_queue_\n   and inflate RTT measurements.\n2. Coupled queue delay sampling: Updates UpdateBaseMarkingProbability()\n   to sample max(l4s_queue_delay, classic_queue_delay) per RFC 9332 so\n   alternating dequeues between classic and L4S queues do not cause\n   negative integral updates while both queues are backlogged.\n\nBug: webrtc:447037083, webrtc:42225697\nChange-Id: Ie0cc4fb39ad9e5c9f412a2046f648381f94d5f13\nReviewed-on: https://webrtc-review.googlesource.com/c/src/+/508180\nReviewed-by: Rasmus Brandt \u003cbrandtr@webrtc.org\u003e\nCommit-Queue: Per Kjellander \u003cperkj@webrtc.org\u003e\nCr-Commit-Position: refs/heads/main@{#48842}\n",
