+- **Post #106 (DGPP author, the newest release notes = the HEAD `d9311e72` that
+  moved past our `3ad63d6b` pin)** adds: **dense Qwen3.8-27B** support, **three
+  quantization options across Qwen and full GLM-5.3**, `DGPP_NO_SWAP=1` (launch
+  ranks in a systemd scope that disallows swap — directly relevant to the GB10
+  unified-memory swap problem), a 1-second decode-gap target (worst mixed-
+  workload pause 1.8s → 0.5s), and faster long-context GLM prefill. **This is a
+  strong reason to bump the DGPP pin** (supervised — read the full changelog +
+  re-bench; the marker keys on `rev`, so a bump cleanly rebuilds).
+- **Post #73 (community 2x DGPP)**: 2× ASUS GX10, driver 580.173.02, CUDA
+  13.0.88, **one ConnectX-7 RoCE lane per node (200G, GID 3) via a switch** —
+  matches our fabric. Confirms DGPP wants an explicit single-lane selection.
+- The thread does NOT document the exact `DGPP_ROCE_DEVICES` value syntax (only
+  `DGPP_NO_SWAP`). The device names come from the preflight output
+  (`roceP2p1s0f0/f1`, `rocep1s0f0/f1`); the DGPP repo docs/config are the source
+  of truth for the exact env format. Candidate launcher follow-up: a
+  `[dgpp].roce_devices` recipe field → emit `DGPP_ROCE_DEVICES` in the `.env`.
