feat(train): compact WiFlow-STD presets in Rust + tiny edge artifact (ADR-152)

WiFlowStdConfig gains half()/quarter()/tiny() mirroring the overnight sweep
exactly: TcnGroupsMode (Fixed/Gcd/Depthwise), input_pw_groups, derived
stride schedule and decoder-mid (all default to upstream behavior; legacy
serde JSON unaffected). Param formulas pin to trained ground truth first
try: 843,834 / 338,600 / 56,290; default 2,225,042 pin and 1.192e-7 parity
unchanged. 248 tests green.

Tiny edge artifact (tiny_edge_bench.py): ONNX fp32 = 295 KB, 0.66 ms/win
(~1,500/s CPU), 94.11% PCK@20 (matches sweep clean-test exactly; parity
1.49e-7). Static int8 is a bad trade at this scale (-1.43pt, +19% MPJPE,
-16% size, slower) — recorded as negative result. Export note: width-16
breaks AdaptiveAvgPool((15,1)) TorchScript export; replaced by exact
mean+matmul equivalent, proven by parity.

### Compact-variant edge artifacts (MEASURED, 2026-06-11)
Edge pipeline for the **tiny** checkpoint (56,290 params), same machinery and
protocol as the full-model edge rows above (this Windows box, torch
2.12.0+cpu, onnxruntime 1.26.0; dynamic-batch opset-17 TorchScript export;
static QDQ **Percentile(99.99) conv-only** int8 calibrated on **512**
corruption-free TRAIN-split windows; accuracy on the identical 10k-window
seed-42 clean test subset; latency = median ms/window over 3 interleaved
reps, with the full-model fp32/int8 sessions interleaved as same-session
references). Script: `tiny_edge_bench.py`; raw:
`results/edge_optimization.json` (`tiny_variant`). Torch-vs-ORT parity on the
stored fixture input: **max abs diff 1.5e-7 — PASS** (< 1e-4). The tiny fp32
subset PCK@20 (94.11%) matches the full clean-test sweep figure (94.11%)
exactly, so the subset remains representative.
Two forced deviations, both recorded in the JSON:
1. **Adaptive-pool export rewrite.** tiny's derived stride schedule
`[2,1,1,1]` leaves feature width 16, and the TorchScript exporter rejects
`AdaptiveAvgPool2d((15,1))` when 15 is not a factor of the input height
(the full model never hit this — its width was exactly 15). Since the
pool over a fixed-size map is a fixed linear operator, the export wrapper
replaces it with `mean(-1)` (W axis, a factor) + a constant averaging
matmul using PyTorch's exact bin rule; the parity check (vs the original
torch model with the real pool) proves exactness.
2. **Calibration count 512, not "~500"**: ORT 1.26's histogram collector
`np.asarray()`'s the per-batch maxima, so the calibration count must be a
multiple of the 64-window calibration batch or the ragged last batch
crashes it (the earlier static-PTQ run dodged this by using exactly 512).

| full ONNX fp32 (same-session ref) | 8.97 MB | 2.27 | 1.42 | 96.68% | 99.15% | 0.00936 |
| full static QDQ Percentile conv-only (same-session ref) | 2.53 MB | 5.53 | 3.82 | 96.61% | 99.16% | 0.01031 |
| **tiny ONNX fp32** | **0.295 MB** | **0.66** | **0.24** | **94.11%** | 99.37% | 0.01253 |
| tiny static QDQ Percentile conv-only | 0.248 MB | 0.85 | 1.03 | 92.68% | 99.33% | 0.01491 |
(tiny torch `.pth` checkpoint for reference: 0.34 MB on disk; 56,290 fp32
params ≈ 225 KB of weights.)
Findings:
- **The smallest deployable WiFlow-class model is the tiny ONNX fp32
artifact: ~295 KB on disk, 0.66 ms/window batch-1 CPU (~1,500 windows/s),
94.1% PCK@20** — 30× smaller and ~3.4× faster (in-session) than the full
ONNX fp32 model for 2.6 pt PCK@20.
- **int8 is a bad trade at this scale.** Static QDQ conv-only — the recipe
that cost the full model only 0.07 pt — costs tiny **1.43 pt** PCK@20
(94.11 → 92.68%) and +19% MPJPE, saves only 47 KB (16%; QDQ scales and
the fp32 BN/attention glue are proportionally larger in a small graph),
and is *slower* than tiny fp32 (0.85 vs 0.66 ms b1; 1.03 vs 0.24 ms b64 —
QDQ kernel overhead dominates when the convs are this small). A 56k-param
model has little redundancy left to absorb weight+activation rounding.
- Deployment guidance, compact edition: ship tiny as **ONNX fp32** — at
295 KB the int8 size saving solves no real constraint and costs accuracy
and speed. If ~250 KB vs ~295 KB ever matters, weight-only quantization
would be the thing to try next, not QDQ.

"""ADR-152 efficiency-sweep follow-up: edge pipeline for the TINY compact
WiFlow-STD variant (56,290 params, results/tiny_best.pth, trained overnight
2026-06-10/11 -- see RESULTS.md "Efficiency sweep").
Headline question: what does the smallest deployable WiFlow-class model look
like (KB + ms + PCK)? Reuses the onnx_bench.py / static_ptq_bench.py
machinery on the tiny checkpoint:
1. Load tiny_best.pth with remote/sweep/model_compact.py
(depthwise TCN groups, input_pw_groups=4, conv [2,4,8,16], attn groups 2).
2. Export ONNX: dynamic batch, opset 17, TorchScript exporter (dynamo=False)
-- same recipe that worked for the full model; verified at batch 1/2/64.
One forced deviation: tiny's stride schedule [2,1,1,1] leaves final_width
16, and the TorchScript exporter cannot export AdaptiveAvgPool2d((15,1))
when 15 is not a factor of the input height (the full model never hit
this -- its width was exactly 15). The adaptive pool over a fixed-size
feature map is a fixed linear map, so the export wrapper replaces it with
an exact matmul equivalent (PyTorch adaptive-pool bin semantics:
bin i averages rows floor(i*H/K)..ceil((i+1)*H/K)); the W axis (20->1,
a factor) becomes mean(-1). Exactness is proven by the parity check
below, which compares against the ORIGINAL torch model with the real
AdaptiveAvgPool2d.
3. Torch-vs-ORT parity on the stored fixture input
(results/parity_fixture.npz, batch 2, seed 42 -- same 540x20 input layout;
reference output recomputed with the tiny torch model). PASS < 1e-4.
4. Static QDQ conv-only int8 (quant_pre_process + quantize_static,
per-channel QInt8 weights+activations, Percentile(99.99) calibration on
512 corruption-free TRAIN-split windows -- the winning recipe and
calibration count from static_ptq_bench.py. 512, not "about 500":
ORT 1.26's histogram collector np.asarray()'s the per-batch maxima, so
the calibration count must be a multiple of the batch size 64 or the
ragged last batch crashes it).
5. Disk size + CPU latency b1/b64 (3 interleaved reps, median ms/window)
for tiny fp32 + tiny int8, with the full-model ONNX fp32 + static-int8
sessions interleaved as same-session references.
6. Accuracy (PCK@20/50 + MPJPE) on the identical 10k-window seed-42
corruption-free test subset for tiny fp32 + tiny int8.
