+  `stacks/chatterbox-fast/` (scheduler + app + sim tests + Dockerfile/compose),
+  live on **irv-ml1 :8197** (container `chatterbox-fast`, healthy) BESIDE the live
+  `chatterbox` :8196. Measured: **TTFB ~0.5s** (vs ~5.2s one-shot), no starvation,
+  RTF ~3.9-4.0× on A6000. **GPU = A6000 (device 1) ONLY** — turbo loads **fp32**
+  (NOT the ~2.5GB fp16 old notes claimed), measured **5.34 GB**, so the 3090's
+  ~3.8GB free does NOT fit. Perf: TF32/SDPA on (don't move TTFA — AR-decode-bound;
+  bf16 deferred, no clean fp32→bf16 cast path). Context-priming for join coherence
+  TRIED + REVERTED (discard-cut leaks prefix — see Tried/abandoned); coherence loss

   - **Goal:** cut time-to-first-audio from ~2.5s → sub-second via streaming,
     keep turbo quality. Workload = single-stream interactive.
   - **Chosen approach = adaptive buffer-ratchet chunking** (operator's idea):
