# osworld-long-pack candidates (focuschain-ab-long extension)

candidates.csv: all 41 unflagged feasible tasks where BOTH published
Pointer models (sonnet-4-6, opus-4-7) needed >=20 single-action steps —
'structurally long' (both-model minimum filters out thrash-driven length).
Sources: pointer_png_index.csv step counts; exclusions identical to
osworld-40-pack (benchmark-integrity non-AGENT_FAIL categories + infeasible-type).

long-pack-24.json/.csv: the 24 longest candidates NOT already in osworld-40-pack.
Config intentionally matches the main focuschain-ab run (Sonnet 4.6/OpenRouter,
batched actions, 960x540, max_steps=50, no thinking) so the 10 overlapping
long tasks from the main pack can be pooled in a combined long-horizon analysis.
Blocks: treatment-L then control-L, 1 run/arm (budget-bound); pre-registered
follow-up for a definitive answer: 3+ runs/arm on all 41 candidates.
