+| [Qwable-3.6-27b: the distill every cheap eval passes, SWE-bench fails](reports/qwable-3.6-27b-q4.md) · [chart](reports/qwable-27b-flat-cliff.png) | A dense Qwen3.6-27B + Fable-5-style SFT, measured controlled vs its base at matched Q4_K_M. Quality (93.4 vs 94.0) AND the synthetic Agentic Score (97.64 vs 98.19) stay flat — but real SWE-bench Verified resolve drops 18 → 11/30 and give-ups rise 7 → 13. Quant ruled out (base Q6 → Q4 = −1 bug). The agentic board would call it neutral; only the reality anchor caught the give-up regression — a 3rd failure mode, and the inverse of the MoE Qwable-v1 (whose synthetic honestly declined). |
 | [Qwable-v1: agentic distillation regresses vs base](reports/qwable-v1.md) · [chart](reports/qwable-decline.png) | A Claude-Code/Fable-5-distilled "agentic coder" (Qwen3.6-35B-A3B) measured controlled vs its vanilla base + the Opus-reasoning-distill, same Q5_K_M. Every post-train step LOWERS the agentic score (99.58 → 97.92 → 96.25), and real SWE-bench Verified resolve drops 19 → 11/30 with give-ups nearly doubling (9 → 16 empty patches). Not a mirage — synthetic fairly predicts real here; the distillation regressed a top-tier base (the vanilla base ties best real resolve on the board). |
 | [ECHO maze microcosm](reports/echo-maze-microcosm.md) · [chart](reports/echo-maze-microcosm.png) | ECHO's "world model for free" env-token loss, isolated in a 10M from-scratch maze transformer (behavior cloning; the only A/B is the loss mask). A clean null under both observation regimes — full-obs and walls-only — every gap inside the seed spread, no growth with maze size. The free aux loss is worth exactly that in pure imitation; the reported gain must live in ECHO's on-policy RL coupling, not the loss as a plug-in. (The paper has no maze — this microcosm is original, verified by grepping the source + repo.) |
 | [Spec-decode three-way (Gemma 4 26B-A4B)](reports/specdecode-gemma-4-26b-a4b.md) · [chart](reports/specdecode-gemma-4-26b-a4b.png) | MTP vs EAGLE-3 vs DFlash on one RTX 5090 (vLLM 0.21, sm_120), including the EAGLE-3 leg nobody publishes. Single-stream near-tie: DFlash 2.19x, MTP 2.13x, EAGLE-3 1.69x — DFlash is feast-or-famine (prose 1.04x, repetitive 4.37x), MTP the steady all-rounder. Six consumer-Blackwell fixes to run it at all (NVFP4 to MARLIN, FLEX_ATTENTION for the #42068 attention deadlock) plus a self-caught /metrics parser bug. Dense 31B excluded: no clean quant fits 32GB. |
