"content": "# Curating a raw web pool for a broad high-quality target\n\n## Hypothesis\n\nFor a fixed 12M-token budget drawn from a 200M-token raw web pool, held-out\nperplexity on a broad high-quality target is governed **first by register-mixture\nmatch and only second by document-level \"quality\"**.\n\nConcretely: the target is an equal-parts mixture of encyclopedic prose, general\nhigh-quality web prose, news, and technical Q&A. A random 6% slice of raw web\nunder-represents encyclopedic and technical-Q&A text badly. So the winning\ncriterion is *domain-matched importance weighting with an explicit per-register\ntoken quota*, where the quota is enforced in the **priority order** of the\nselection (so the budget-truncated prefix, not just the whole list, carries the\ntarget mixture). Quality filtering matters, but only as a junk floor: past that\npoint it is actively harmful, because every document a filter removes forces the\nquota to reach one document deeper into a worse-matching tail.\n\nPrediction, stated before the final measurement: mixture control buys more than\nany filter, and the filter-strength response curve is **non-monotonic** — an\ninterior optimum, with both over-filtering and no-filtering worse.\n\n## Mechanism (observable, not the final perplexity)\n\nThe mechanism is *distributional coverage of the target's registers*, so it is\nobservable directly in the data and in per-register loss — independent of the\nfinal score.\n\n1. **Register composition of the selection.** Classify pool documents by surface\n form (HTML/code markup → technical Q&A; whitespace-before-punctuation and\n encyclopedic phrasing → encyclopedic; else prose/news). A random 12M-token\n selection is dominated by forum/blog/boilerplate prose and contains only a few\n percent of markup-bearing technical Q&A. The curated selection's 12M prefix\n should hold ≈30% encyclopedic / ≈45% prose+news / ≈25% technical Q&A, by\n construction, and this is printed by `curate.py`.\n2. **Per-register held-out loss.** If the mechanism is mixture coverage, then\n relative to the random baseline the *largest* loss reductions must appear on\n the registers the random slice starves — technical Q&A and encyclopedic — and\n the *smallest* on general web prose, which random selection already covers.\n A global \"we just picked cleaner text\" story predicts a roughly uniform\n improvement across registers instead.\n3. **Ablation ordering.** Removing mixture control (one global importance model,\n everything else identical) should cost more than removing the quality floor\n entirely. Observed on dev: no-mixture 411.9 vs no-filter 355.0 vs full 317.8\n against a random baseline of 485.5 — mixture is the dominant term, as predicted.\n4. **Non-monotonic filter response.** Sweeping only the quality floor, holding\n mixture and ranking fixed: strict (64.7k docs surviving) 362.7 → medium (96.7k)\n 333.9 → loose (117.9k) 324.5 → none (182.0k) 355.0. An interior optimum, as\n predicted; the filter is a junk floor, not a quality maximiser.\n5. **Hard top-k beats stochastic resampling.** Adding Gumbel noise to the\n importance ranking (DSIR-style resampling for diversity, τ=0.6) costs ~40 PPL\n (358.4 vs 317.8). At 6% selection ratio the budget is small enough that\n diversity within a register is not the binding constraint; match is.\n6. **Deduplication frees budget.** Near-duplicate removal (MinHash banding on\n 5-word shingles) drops 22.6k of 182.0k documents. Since duplicated tokens buy\n no new information under a fixed budget, disabling dedup should cost real\n perplexity: observed 345.7 vs 333.9 at otherwise identical settings.\n\n## Falsification\n\nThe hypothesis is wrong if any of these hold:\n\n- **Mixture is not the dominant lever.** If a single global importance model with\n no quota (`--no_mix`) matches or beats the register-quota selection, the claim\n fails. (Measured: 411.9 vs 317.8 — survives.)\n- **The filter response is monotonic.** If loosening the quality floor all the way\n to *no filter* keeps improving perplexity, then \"quality floor with an interior\n optimum\" is the wrong description and plain domain matching suffices.\n (Measured: no-filter 355.0 is worse than loose 324.5 — survives.)\n- **Per-register gains are flat.** If the loss reduction versus the random\n baseline is uniform across encyclopedic / prose / Q&A, the mechanism is not\n mixture coverage but generic cleanliness, and the quota is incidental.\n- **Quota position is irrelevant.** If shuffling the selection (destroying the\n interleaved priority order, so the 12M prefix mixture drifts from the target\n mixture) does not hurt, then enforcing the quota *in priority order* is\n unnecessary machinery.\n- **The dev optimum does not transfer.** If the tuned mixture/filter setting loses\n to the untuned nominal 25/50/25 setting on the hidden held-out sample, the\n selection was fitted to the dev sample rather than to the domain. This is the\n live risk: the mixture response is flat (317.8 / 318.2 / 320.3 across\n 0.30–0.34 encyclopedic share), so the setting was chosen from a plateau rather\n than a sharp peak, which limits but does not eliminate the exposure.\n\n## Transfer\n\n- **Different target mixture.** The pipeline takes the target's register mixture\n as input, not as an assumption. Point `curate.py` at any target sample and the\n same machinery (segment → classify register → per-register importance model →\n quota → interleave) rebalances the selection. `--clusters K` replaces the\n hand-written register classifier with k-means over the target documents, so it\n runs on a target whose registers you cannot name in advance (measured 341.5 at\n K=6 — worse than hand-labelled registers here, because 6 topic clusters over\n 2.7k target documents overfit the dev sample's *topics*, while surface-form\n registers generalise).\n- **Different budget.** Because the quota is enforced by interleaving, *every*\n prefix of the emitted list carries the target mixture.

[metadata] {"type": "create", "filePath": "/workspace/claim.md", "content": "# Curating a raw web pool for a broad high-quality target\n\n## Hypothesis\n\nFor a fixed 12M-token budget drawn from a 200M-token raw web pool, held-out\nperplexity on a broad high-quality target is governed **first by register-mixture\nmatch and only second by document-level \"quality\"**.\n\nConcretely: the target is an equal-parts mixture of encyclopedic prose, general\nhigh-quality web prose, news, and technical Q&A. A random 6% slice of raw web\nunder-represents encyclopedic and technical-Q&A text badly. So the winning\ncriterion is *domain-matched importance weighting with an explicit per-register\ntoken quota*, where the quota is enforced in the **priority order** of the\nselection (so the budget-truncated prefix, not just the whole list, carries the\ntarget mixture). Quality filtering matters, but only as a junk floor: past that\npoint it is actively harmful, because every document a filter removes forces the\nquota to reach one document deeper into a worse-matching tail.\n\nPrediction, stated before the final measurement: mixture control buys more than\nany filter, and the filter-strength response curve is **non-monotonic** — an\ninterior optimum, with both over-filtering and no-filtering worse.\n\n## Mechanism (observable, not the final perplexity)\n\nThe mechanism is *distributional coverage of the target's registers*, so it is\nobservable directly in the data and in per-register loss — independent of the\nfinal score.\n\n1. **Register composition of the selection.** Classify pool documents by surface\n form (HTML/code markup → technical Q&A; whitespace-before-punctuation and\n encyclopedic phrasing → encyclopedic; else prose/news). A random 12M-token\n selection is dominated by forum/blog/boilerplate prose and contains only a few\n percent of markup-bearing technical Q&A. The curated selection's 12M prefix\n should hold ≈30% encyclopedic / ≈45% prose+news / ≈25% technical Q&A, by\n construction, and this is printed by `curate.py`.\n2. **Per-register held-out loss.** If the mechanism is mixture coverage, then\n relative to the random baseline the *largest* loss reductions must appear on\n the registers the random slice starves — technical Q&A and encyclopedic — and\n the *smallest* on general web prose, which random selection already covers.\n A global \"we just picked cleaner text\" story predicts a roughly uniform\n improvement across registers instead.\n3. **Ablation ordering.** Removing mixture control (one global importance model,\n everything else identical) should cost more than removing the quality floor\n entirely. Observed on dev: no-mixture 411.9 vs no-filter 355.0 vs full 317.8\n against a random baseline of 485.5 — mixture is the dominant term, as predicted.\n4. **Non-monotonic filter response.** Sweeping only the quality floor, holding\n mixture and ranking fixed: strict (64.7k docs surviving) 362.7 → medium (96.7k)\n 333.9 → loose (117.9k) 324.5 → none (182.0k) 355.0. An interior optimum, as\n predicted; the filter is a junk floor, not a quality maximiser.\n5. **Hard top-k beats stochastic resampling.** Adding Gumbel noise to the\n importance ranking (DSIR-style resampling for diversity, τ=0.6) costs ~40 PPL\n (358.4 vs 317.8). At 6% selection ratio the budget is small enough that\n diversity within a register is not the binding constraint; match is.\n6. **Deduplication frees budget.** Near-duplicate removal (MinHash banding on\n 5-word shingles) drops 22.6k of 182.0k documents. Since duplicated tokens buy\n no new information under a fixed budget, disabling dedup should cost real\n perplexity: observed 345.7 vs 333.9 at otherwise identical settings.\n\n## Falsification\n\nThe hypothesis is wrong if any of these hold:\n\n- **Mixture is not the dominant lever.** If a single global importance model with\n no quota (`--no_mix`) matches or beats the register-quota selection, the claim\n fails. (Measured: 411.9 vs 317.8 — survives.)\n- **The filter response is monotonic.** If loosening the quality floor all the way\n to *no filter* keeps improving perplexity, then \"quality floor with an interior\n optimum\" is the wrong description and plain domain matching suffices.\n (Measured: no-filter 355.0 is worse than loose 324.5 — survives.)\n- **Per-register gains are flat.** If the loss reduction versus the random\n baseline is uniform across encyclopedic / prose / Q&A, the mechanism is not\n mixture coverage but generic cleanliness, and the quota is incidental.\n- **Quota position is irrelevant.** If shuffling the selection (destroying the\n interleaved priority order, so the 12M prefix mixture drifts from the target\n mixture) does not hurt, then enforcing the quota *in priority order* is\n unnecessary machinery.\n- **The dev optimum does not transfer.** If the tuned mixture/filter setting loses\n to the untuned nominal 25/50/25 setting on the hidden held-out sample, the\n selection was fitted to the dev sample rather than to the domain. This is the\n live risk: the mixture response is flat (317.8 / 318.2 / 320.3 across\n 0.30–0.34 encyclopedic share), so the setting was chosen from a plateau rather\n than a sharp peak, which limits but does not eliminate the exposure.\n\n## Transfer\n\n- **Different target mixture.** The pipeline takes the target's register mixture\n as input, not as an assumption. Point `curate.py` at any target sample and the\n same machinery (segment → classify register → per-register importance model →\n quota → interleave) rebalances the selection. `--clusters K` replaces the\n hand-written register classifier with k-means over the target documents, so it\n runs on a target whose registers you cannot name in advance (measured 341.5 at\n K=6 — worse than hand-labelled registers here, because 6 topic clusters over\n 2.7k target documents overfit the dev sample's *topics*, while surface-form\n registers generalise).\n- **Different budget.** Because the quota is enforced by interleaving, *every*\n prefix of the emitted list carries the target mixture. The same\n `selection.json` is therefore mixture-correct at 6M or 24M tokens, not just at\n 12M; only the depth reached into each register's ranking changes.\n- **Different pool.** Nothing in the criterion is specific to this pool. The\n background distribution is estimated from the pool itself, so the importance\n ratio adapts: a cleaner pool yields a flatter ratio and the quality floor does\n less work.\n- **What should not transfer.** Hard top-k beating stochastic resampling is a\n *small-budget* result.
