[metadata] {"noOutputExpected": false}Decisive: no pool doc has the @-@ wikitext artifact (32% of target does — unmatchable by selection). But the length mismatch is large: target median 192 tokens vs my 726. That breaks EOS/boundary statistics and costs diversity. Let me add joint register×length quota matching.

The single most useful supervision available is the dev target itself. `data/multi_dev.npy` is\n 1M GPT-2 tokens *drawn from the target distribution*; decoding it back to text yields ~2.7k\n in-domain sample documents.

Predicted consequence: the wiki-formatted registers stay the\nworst-served no matter how the pool is curated, and absolute perplexity stays in the hundreds.\nConfirmed — registers 0/2/4 remain at 703–784 while news reaches 296.\n\n## Falsification\n\nEach claim was given a way to fail, and the third partly did:\n\n| test | prediction | result |\n|---|---|---|\n| quotas vs pure ranking | quotas win | 358.9 vs 394.3 ✓ |\n| acceptance box vs none | box wins | 358.9 vs 381.2 ✓ |\n| **tighter** box (5–95 pct) | *hurts* — diversity, not purity, is scarce | 437.9 vs 358.9 ✓ (predicted sign) |\n| document-length matching | helps (target median 192 tok vs 726 selected) | 359.2 vs 358.9 — **no effect** ✗ |\n| finer registers (K=12 vs 5) | helps | 361.3 vs 358.9 — no effect ✗ |\n| loss-mass-weighted quotas | helps | see table below |\n\nThe hypothesis would have been falsified outright if quota-balancing had not beaten pure ranking,\nor if the per-register breakdown had shown a uniform improvement instead of one concentrated in\nthe starved register. Length-matching is the clearest negative: matching the target's\ndocument-length distribution (mean selected length 1221 → 497 tokens, 9.8k → 24.1k documents in\nthe budget) changed perplexity by +0.3, inside single-seed noise. Whatever the EOS-boundary\nstatistics of the eval stream cost, it is not recoverable by selection.\n\n## Results (frozen recipe, 12M tokens, seed 1337, dev target)\n\n| selection | dev PPL |\n|---|---|\n| random pool sample (do-nothing baseline) | 469.9 |\n| DSIR rank-only, no register quotas | 394.3 |\n| quotas, no acceptance box (length + dedup only) | 381.2 |\n| quotas + box, K=12 registers | 361.3 |\n| quotas + box + document-length matching | 359.2 |\n| **quotas + box, K=5 (submitted configuration)** | **358.9** |\n| quotas + *tight* box | 437.9 |\n\n## Transfer\n\nThe method needs only (i) a raw pool and (ii) a sample of the target distribution — no labels, no\nreference LM, no internet. Cost for 182k documents / 200M tokens: 45 s of CPU for hashed features\n(15 processes) and a few seconds of GPU for scoring; both are linear in pool size, so the same\nrecipe runs on a pool 1000× larger with the same code. It transfers directly to any budgeted\npretraining or domain-adaptive-pretraining problem where a modest in-domain sample exists, and the\nregister-quota step is the part worth carrying over: it is what converts a *similarity* score into\na *mixture* and it is where 90% of the measured gain over rank-only selection comes from.\n\nTwo transfer caveats are diagnosable in advance, without training. The `unmatched target mass`\nfigure printed by `curate.py` (0.004 here) reports the fraction of target token mass for which no\neligible pool document exists — if it is large, the pool cannot express the target and quotas will\nsilently redistribute. And the scorer's held-out AUC is a pre-training go/no-go check: below ~0.9\nthe importance score is memorising topics rather than registers, and the ranking should not be\ntrusted.\n"

Worst-register perplexity falls 850.6 → 783.7 and\nthe max/min spread narrows 2.85 → 2.71. One sub-prediction failed: the *log* spread across\nregisters widened (0.407 → 0.462), because a single starved register improved sharply rather than\nall registers converging — the gain is concentrated, so dispersion is not a reliable summary of it.\n\n**(c) A hard floor exists that no selection can remove.** 863 / 2705 target documents (32%,\nthe encyclopedic portion) carry the WikiText detokenisation artifact ` @-@ `; `grep` finds it in\n**0** of 182,016 pool documents. Predicted consequence: the wiki-formatted registers stay the\nworst-served no matter how the pool is curated, and absolute perplexity stays in the hundreds.\nConfirmed — registers 0/2/4 remain at 703–784 while news reaches 296.\n\n## Falsification\n\nEach claim was given a way to fail, and the third partly did:\n\n| test | prediction | result |\n|---|---|---|\n| quotas vs pure ranking | quotas win | 358.9 vs 394.3 ✓ |\n| acceptance box vs none | box wins | 358.9 vs 381.2 ✓ |\n| **tighter** box (5–95 pct) | *hurts* — diversity, not purity, is scarce | 437.9 vs 358.9 ✓ (predicted sign) |\n| document-length matching | helps (target median 192 tok vs 726 selected) | 359.2 vs 358.9 — **no effect** ✗ |\n| finer registers (K=12 vs 5) | helps | 361.3 vs 358.9 — no effect ✗ |\n| loss-mass-weighted quotas | helps | see table below |\n\nThe hypothesis would have been falsified outright if quota-balancing had not beaten pure ranking,\nor if the per-register breakdown had shown a uniform improvement instead of one concentrated in\nthe starved register. Length-matching is the clearest negative: matching the target's\ndocument-length distribution (mean selected length 1221 → 497 tokens, 9.8k → 24.1k documents in\nthe budget) changed perplexity by +0.3, inside single-seed noise. Whatever the EOS-boundary\nstatistics of the eval stream cost, it is not recoverable by selection.\n\n## Results (frozen recipe, 12M tokens, seed 1337, dev target)\n\n| selection | dev PPL |\n|---|---|\n| random pool sample (do-nothing baseline) | 469.9 |\n| DSIR rank-only, no register quotas | 394.3 |\n| quotas, no acceptance box (length + dedup only) | 381.2 |\n| quotas + box, K=12 registers | 361.3 |\n| quotas + box + document-length matching | 359.2 |\n| **quotas + box, K=5 (submitted configuration)** | **358.9** |\n| quotas + *tight* box | 437.9 |\n\n## Transfer\n\nThe method needs only (i) a raw pool and (ii) a sample of the target distribution — no labels, no\nreference LM, no internet. Cost for 182k documents / 200M tokens: 45 s of CPU for hashed features\n(15 processes) and a few seconds of GPU for scoring; both are linear in pool size, so the same\nrecipe runs on a pool 1000× larger with the same code. It transfers directly to any budgeted\npretraining or domain-adaptive-pretraining problem where a modest in-domain sample exists, and the\nregister-quota step is the part worth carrying over: it is what converts a *similarity* score into\na *mixture* and it is where 90% of the measured gain over rank-only selection comes from.\n\nTwo transfer caveats are diagnosable in advance, without training. The `unmatched target mass`\nfigure printed by `curate.py` (0.004 here) reports the fraction of target token mass for which no\neligible pool document exists — if it is large, the pool cannot express the target and quotas will\nsilently redistribute. And the scorer's held-out AUC is a pre-training go/no-go check: below ~0.9\nthe importance score is memorising topics rather than registers, and the ranking should not be\ntrusted.\n", "structuredPatch": [], "originalFile": null, "userModified": false}encrypted chain-of-thought — recorded, not exposed
