#1017/#2230 residency measurement: the host→device operand bytes that flatten_device_sae_data / flatten_device_sae_frame_data re-upload on EVERY matrix-free PCG solve (hence on every LM ridge-ladder escalation trial), broken out by category. Lets the a100 job confirm which sub-lane a real fit takes — legacy sparse (⊗ I_p a_phi/local_jac) vs framed dense (per-row row_htbeta at the factored border) — and size the transfer a base-resident frame would remove. Pure host accounting, no device contact, so it is CPU-CI testable without CUDA.

Fields

framed: bool

true when the framed dense per-row cross path is active (frame present).

beta_dim: usize

Border width k (= beta_dim).

a_phi_pairs: usize

Per-row support a_phi: total (row, weight) pairs and their bytes.

a_phi_bytes: usize

local_jac_elems: usize

Per-row local Jacobians local_jac: total f64 and their bytes.

local_jac_bytes: usize

smooth_bytes: usize

Smooth penalty factors λ S_k: bytes.

sparse_g_bytes: usize

Sparse G co-occurrence blocks (legacy ⊗ I_p): bytes.

row_htbeta_bytes: usize

Framed per-row dense cross row_htbeta: bytes (0 on the legacy path). This is the 34MiB-vs-31GiB discriminator the #2230 design report flagged: a full factored-border dense cross balloons here, a legacy fit leaves it at 0.

row_htbeta_rows: usize

Number of rows carrying a non-empty framed row_htbeta slab.

frame_blocks_bytes: usize

Framed G_{ij} ⊗ W_{ij} co-occurrence factors: bytes (0 on legacy).

total_bytes: usize

Sum of the data-category bytes above — the per-solve re-upload total.
