 - One greedy pass per problem, 63 problems, the same limits as the rest of this page. The model card recommends a longer output budget (`-n 16384` or more with `-c 65536`); 32k is this page's budget for every row, not a Bonsai-specific choice.

+## Addendum 2026-10-25: Underdog-Saluki-27B and Qwen3.8-27B GSQ-RCO IQ2_XS
+
+The two other small files of the [sub-10 GB study](sub10-qwen38-27b.md) ran the same 63 problems under the same regime (thinking on, `max_tokens 32768`, `ctx 40960`, greedy, exact-number veto on; 0 vetoes fired). Same mainline llama.cpp b10371 (`5d16e81dd`) as the nine rows above; the legs finished 2026-10-25 (idle-queue item `67-sub10-qwen38-27b`). The chart at the top is the nine-row card as published and is left unchanged.

+### Reads (2026-10-25)
+
+1. **GSQ-RCO is level with Saluki on AIME (23 of 30 each, 2 / 2 discordant) and ahead on HMMT (19 against 16; 5 / 2, p = 0.45).** Neither gap is significant on 63 problems.
+2. **HMMT is a token-budget floor for both small files.** Saluki capped on 18 of 33 problems (54.5%, median completion 32,768 tokens) and is right on all 15 it finished; GSQ-RCO capped on 14 (43.8% by the harness over the 32 problems with a recorded completion, 42.4% of 33) against 12 for Q6_K and UD-IQ3_XXS. Read the HMMT column as how many chains ended inside 32k, not as the file's maths ceiling. AIME caps on 20% to 27% for every row, comparison rows included.
+3. **Saluki's model card lists AIME 2026 avg@4 80.0; this single greedy pass solved 23 of 30 (76.67).** 80.0% of 30 is 24 problems: one problem apart, inside the noise of a 30-problem set and a different harness. Not a contradiction.

+### Limits (2026-10-25)
+
+- One of GSQ-RCO's HMMT problems returned an HTTP 500 (context size exceeded), was scored wrong and counts as finished (1 request error in the detail json; zero on the other three legs).
+- One greedy pass per problem, 63 problems; the other limits of this page apply. The sub-10 GB report's [2026-10-25 addendum](sub10-qwen38-27b.md#addendum-2026-10-25-gpqa-diamond-and-this-years-contests-for-saluki-and-gsq-rco) carries the GPQA Diamond cells and the cap-split reads.
