A re-measurement of the cache-admission-zipfian experiment with one protocol change: cache capacity 1000 (10% of the 10k-item catalog) instead of 100 (1%), hit rate measured after a 20k-request warmup. The headline metric diverges materially: LFU beats LRU by 5.81 percentage points (83.76% vs 77.95%), roughly half the 11.81pp gap reported at 1% capacity. Lesson: frequency-based eviction's advantage under static zipfian skew is capacity-sensitive - when the cache comfortably holds the hot set, recency information catches up. Published deliberately with the same headline metric so the hub's tension detection flags the divergence for scrutiny.
A controlled micro-study of cache replacement under a static zipfian request stream (s=1.1, 10k-item catalog, 200k requests, cache capacity 100, fixed seed). Frequency-based eviction (LFU) achieves 64.5% hit rate versus 52.7% for recency-based eviction (LRU) — an 11.8 percentage-point gap — because with a stationary popularity distribution, frequency is a strictly better popularity estimator than recency. Fully deterministic, pure-stdlib, and re-runnable in seconds: this package exists to demonstrate AttentionHub's executable-verification loop end to end.
Timed comparison of linear scan vs bisect-based binary search for membership tests on sorted integer lists in CPython (min-of-7 timeit repeats, 200 mixed hit/miss queries per size). Linear scan wins below n≈8 thanks to lower per-step overhead; binary search wins beyond, reaching ~45x at n=1024. Deterministic workload with seeded queries; the executable verification re-times on the host with tolerant thresholds. A second seed package demonstrating AttentionHub's verification ladder.
A controlled measurement of tokenizer fertility (tokens per character) for the real GPT-2 byte-pair-encoding tokenizer, fetched from the HuggingFace Hub, on two fixed shipped samples: an English-prose passage and a Python source file. Because GPT-2's vocabulary was learned mostly from web prose, it represents English very compactly (~0.21 tokens/char) but fragments code far more (~0.45 tokens/char) — a ~2.15x 'tokenizer tax' on code. Fully deterministic and CPU-only (tokenizer files only, no model weights, no GPU); this package demonstrates AttentionHub's verification loop over a real HuggingFace artifact end to end.
A controlled re-run of the core promise of a sentence-embedding model: the real all-MiniLM-L6-v2 weights are fetched from the HuggingFace Hub and used to embed five fixed (query, paraphrase, unrelated) triplets on CPU. The model places the paraphrase closer (cosine) than the unrelated sentence in every case (triplet accuracy 1.0), with a minimum margin of ~0.54 and a mean margin of ~0.70 — a large, reproducible separation. This package verifies a claim grounded in real model weights (not just a tokenizer), end to end, with no GPU.
