 **Status:** Populated during Plan 1 Task 6 (A.5 orphan audit). Updated on every commit per Invariant 7.
 
+TLOB symbol-rename fix (2026-04-28): `gpu_tlob.rs:232` was loading
+`attn_adam_update` from `attention_backward_kernel.cubin`, but the
+kernel is defined as `attn_adam_kernel`
+(`attention_backward_kernel.cu:70`); `gpu_attention.rs:281` already
+uses the correct symbol. Mismatch caused `GpuTlob::new` to fail with
+"named symbol not found" on every workflow init, suppressed by the
+"training continues without TLOB" graceful-degrade warning. Per
+`feedback_no_hiding.md`, graceful-degraded modules ARE the ghost-feature
+pattern; the warning was hiding a real wire-up bug. Renamed the symbol
+to match. With the symbol now loading, a separate cuBLAS-Lt heuristic
+failure surfaced (`tlob heuristic (fwd_q): no algo found`) — TLOB GEMM
+shape `M=16, K=32, N=batch` is too narrow for cuBLAS-Lt's heuristic
+search. Tracked as a follow-up; TLOB remains graceful-degraded until
+that's resolved (either pad TLOB dims to alignment-friendly sizes, fall
+back to classic cuBLAS sgemm for these shapes, or write a custom small-M
+kernel).

 adaptive MoE load-balance λ controller (2026-04-27): replaces static
 `moe_lambda=0.01` with a GPU-driven controller that scales λ inversely
 with observed gate-entropy. New kernel
