Follows #637 (which raised the eval-push payload limit 2 → 25 MiB).

Computer-use environments embed a full 1920×1080 screenshot per step in the trace, so a single rollout's sample exceeds 25 MiB and gets dropped on --push — leaving those runs with no hosted rollout link. Observed while validating the cua_world_v1 / osworld_v2_v1 research environments:

  • sample 0 is too large to upload (53564890 > 26214400 bytes) — cua_world, kimi-k3 (~51 MiB @ 15 turns)
  • sample 0 is too large to upload (78391638 > 26214400 bytes) — osworld_v2, qwen (~75 MiB @ 50 steps)

At ~1.5–3.5 MiB per screenshot, one rollout can run well past 25 MiB, and longer/higher-res computer-use rollouts go higher still (a 50-turn cua rollout would be ~170 MiB). Raises max_payload_bytes 25 → 100 MiB in both the sync and async push_samples (the same two spots #637 touched) for real headroom without compressing traces.

Note: the client-side mirror _MAX_SAMPLES_PAYLOAD_BYTES in verifiers/v1/utils/platform.py (the uv run eval --push path, where the error above is actually raised) carries the same constant — companion PR: PrimeIntellect-ai/verifiers#2222.

Computer-use envs (cua_world, osworld_v2) embed a full screenshot per step, so a
single rollout's trace exceeds the 25 MiB per-batch push cap and is dropped
("sample 0 is too large to upload"): observed cua_world ~51 MiB, osworld_v2
~75 MiB at 50 steps, and longer/higher-res rollouts go higher still. #637 raised
this 2 -> 25; raise it to 100 for real headroom on screenshot-heavy rollouts.

Mirror of PrimeIntellect-ai/prime#818. Computer-use envs (cua_world, osworld_v2)
embed a full screenshot per step, so one rollout's sample exceeds the 25 MiB
push ceiling and is skipped ("sample 0 is too large to upload"): cua_world
~51 MiB, osworld_v2 ~75 MiB at 50 steps, higher for longer rollouts. Match the
Prime Evals client ceiling raised in prime#818.

P2 Badge Keep the payload defaults at the promised 75 MiB

The commit specifies a 75 MiB upload limit, but both the synchronous and asynchronous defaults are set to 100 MiB. Consequently, batches between 75 and 100 MiB are uploaded instead of being split or skipped at the intended boundary, increasing request size and potentially exceeding the service limit this client-side cap is meant to enforce. Set this default—and the corresponding async default—to 75 * 1024 * 1024.
