Gate now keeps 130k docs (junk removed), but code/HTML is extremely scarce in this pool — only 174 docs have HTML markers, so techQA under-filled (1.3M vs 4M target). Let me (a) re-eval this gated selection on GPU and (b) simultaneously measure how much technical content actually exists and inspect the techQA queue.

Gated selection: PPL 317.40 — beats random baseline (474) by ~33%. The quality gate is the key lever. Let me wait for the tech-content scan to decide whether I can source more techQA (currently under-filled).

Technical content is genuinely rare: only 180 docs have HTML markers, 1,736 are code-dense, 5,093 have ≥5 programming-vocabulary tokens. I can't match 25% techQA in exact SO-HTML format, but I can route all available technical/code content into the techQA bucket to give the model code/HTML exposure. Let me broaden techQA sourcing in curate.py.

*Key finding: v3 (forced 25% techQA) = 409.99 — worse than v2 (~11% techQA) = 317.40. Forcing the eval's register proportions backfires: the pool lacks real SO-format techQA, so padding to 25% with code-dense docs (high-entropy, off-format) steals budget from learnable clean prose. Less techQA is better.* Let me parameterize the mix and sweep it.

Even post-gate, the top-ranked docs are still spam: repetition spam ("ArchiveRecipes by by..." ×N), no-space MT text, prime-number dumps, and word-salad SEO gibberish (ids 156574, 45829, 124335, 98806, 32323). The NB scorer rewards keyword-dense spam (high priority = consumed first — very harmful). I need fluency filters: common-word overlap (English/real-text) + type-token ratio (repetition). Let me check v4's number, then add them.

v4 (30/60/10) = 412 — also ~410, like v3. So the regression from 317→410 wasn't the tech fraction — it was routing code-dense docs into techQA at all. v2's win came from the is_html-only code gate (just 174 real HTML docs) + NB-argmax assignment, which excluded the harmful code-dense docs (they fail the prose gate).

Plan: revert to v2-style (html-only code path + NB-argmax), and add the fluency filters (common-word overlap + type-token ratio) to kill the repetition-spam / gibberish / number-dumps I saw. That should push below 317. Let me rewrite the gate.

Quick fix: the print line still references code_ok (renamed to html_ok). Caches are built now, so re-run is fast.

Spam is gone — top docs are now clean encyclopedic + news + technical prose (ids 10550 "The Mitchell Highway is a state highway...", real news, OCaml docs). Mix is the winning low-tech regime (~11% techQA). Let me back this up and eval it.
