Observe-only dest extras lock move.

Dest opengfx1030/vllm-rdna rdna_extras tip is now 3a0786eaa70f (2026-09-30 09:56 UTC). Previous lock was e0112c55e48d (hippihx PR #30).

Dest presence (stay extras)

• W4A8 sdot4 opt-in (w4a8_sdot4_rdna2.{cu,cuh}, moe_w4a8_rdna2.cu). Default off: VLLM_RDNA2_W4A8_SDOT4 unset = W4A16. gfx1030 prefill M≥33, internal W4A16 fallback. MoE W4A8 hard-off under resident MoE. Unique Blivion. Not a second W4 zoo family.
• K_STEP prefill split repair in q_gemm_rdna2_prefill.cu. Dest keeps legacy powers-of-two when k_per_split % K_STEP == 0, else enumerates aligned splits. Zoo still refuse 40-wide.
• extras Lock dest extras tracking to rdna_extras @ 388a61b6 #9 closed-unmerged (superseded by dest W4A8). extras Unslop extras tracking docs after PR #9 merge #10 still skip.

Still skip / not dest

extras drafts #30 (W4 compile-dispatch), #31 (W4 exact-dequant), #32 (EXL3 mul1 / K=1..8 trellis), #33 (FA decode scores), #34 (FA D=128 prefill). #2, #18, #23, #25 unchanged.

Unchanged

• No torch.ops.hippihx.*. Dest Lock dest extras tracking to rdna_extras @ 330b42ab #27 ctypes consume still opt-in / plans not ready.
• VLLM_RDNA_AR still dest-off. Zoo AR_MAX_KB stays 512.
• Do not dump HIP. Do not copy tok/s or extras maxdiff.
• Do not pick Cursor / George / Codex / a17t / Claude until dest migrate.

Tracking docs stay lean: one lock, one SHA index row for 3a0786ea, one defects table. CONTRIBUTING is tip-only.
