Per Class A audit grid no-CPU-compute sites 2+9 verification (audit doc lines
3825/3832): the code-vs-grid disagreement was the GRID being stale, not the
code. Both sites were already resolved in 2026-05-01 close-out follow-up
commits but the grid table verdict columns were never updated.
Site 2 (compute_adaptive_tau): ALREADY-CLOSED
Helper deleted in `a385c1d2b` (chore(sp4): delete compute_adaptive_tau orphan
helper per feedback_wire_everything_up). Verified zero hits across
`crates/`, `services/`, `bin/` for `compute_adaptive_tau` and `q_div_ema`.
Grid row updated: DEFER → CLOSED, with closure SHA recorded.
Site 9 (calibrate_homeostatic_targets): ALREADY-CLOSED
Migrated to GPU in `6d0ac7beb` (fix(sp4): GPU-port calibrate_homeostatic_targets
per feedback_no_cpu_compute_strict). Verified `calibrate_homeostatic_kernel.cu`
exists at `crates/ml/src/cuda_pipeline/calibrate_homeostatic_kernel.cu`,
Rust launcher at `gpu_dqn_trainer.rs:7958-7994` calls
`launch_calibrate_homeostatic` (single-block, 6 threads, mapped-pinned
EMA writeback with `__threadfence_system()`); host-side EMA loop body is gone.
Grid row updated: NEW DISCOVERY → CLOSED, with closure SHA recorded.
Sweep summary section updated: migrations completed 3→4, exceptions 5→4,
deferrals 2→0. Final-grep claim of "1 match remaining" amended to "0 matches
remaining post-close-out". The free-text "Sweep close-out" subsection at lines
3863-3871 was already correct and complete; only the GRID columns and summary
counts were stale.
Audit-doc errors found: 2 sites flagged as open (DEFER + NEW DISCOVERY) when
both were already closed in commits dated 2026-05-01. The narrative close-out
write-up beneath the grid was correct — only the grid table verdict columns
and summary counts had not been kept in sync. No code changes; doc-only fix.
Per feedback_trust_code_not_docs: code wins. Grid now matches reality.
Cumulative WR-plateau fix series (commit M):
- Class C, Class A batches 4a/4b, Class B #1, Class B #2 already landed
- no-CPU-strict sites 2+9 audit-doc cleanup (this commit; NO_OP for code)
