llm_judges: verify the five abstract-quoted papers against raw PDF

NoLiMa effective length was wrong in both files: most models fall below the
85% threshold at 1-4K tokens, not 8-16K (only GPT-4o 8K, GPT-4.1 16K). NoLiMa
32K count was 11 models, not 10. The Loo quote's first sentence was stitched
from two places and is dropped. JudgeLRM's 8.14% is an Introduction number,
not an abstract one, and the abstract quote had lost /14B and its trailing
clause. Shi et al is 'The findings', not 'Our findings'. Body quotes now
replace abstract quotes where the number matters; tags [ID] -> [FT].

Rule of thumb: even in 2026, judges flip ~43% of decisive verdicts on order swap alone; the worst flip >70%. Direction is not universal (Mistral Large 3 goes second-position). Always judge both orders. (Note: an earlier subagent draft misattributed 27.4% to Claude Opus; the raw table puts 27.4% first-shown pick on Mistral Large 3, so I dropped the per-model attributions except the verified worst-case.)

## Honesty flags for this batch
- [FT] entries (Lech Mazur 43%, self-preference DBG 41.7/2.1, RLAIF position-bias direction + averaging mitigation, CAIS/litellm budgets) are copied from raw source I fetched this turn.
- [ID] entries: arXiv id + title confirmed real and on-topic this turn, but the specific in-body number was pulled by a research subagent through WebFetch's summarizer, not from raw PDF. Re-pull before quoting a figure as exact.
- 2026-08-14 (CLAUDE agent): the five papers the litreview quotes (2406.07791, 2504.00050, 2511.00751, 2502.05167, 2307.03172) were re-pulled from raw PDF and moved [ID] -> [FT]. Two numbers here were wrong and are now fixed: NoLiMa effective length was "~8-16K", actually 1-4K for most models, and "10 models drop below 50%" at 32K was 11. Everything else in those five entries held up.
