Run #8 (matrix) failures:
- Cells 2 & 3: RecursionError in patch_tiled_mlp shim. Root cause:
tests/_zoo_aggressive_cuda_spoof.py routed torch.cuda.manual_seed and
manual_seed_all back through torch.manual_seed, but torch.manual_seed
internally calls torch.cuda.manual_seed_all -> infinite recursion.
Fix: no-op the cuda seed APIs (callers already paid the CPU-RNG cost
via torch.manual_seed; CUDA-side seeding has no meaning on a GPU-less
runner). Same fix for cuda.set_rng_state / get_rng_state and
initial_seed / seed / seed_all. Locally re-validated tiled MLP shim:
diff = 0.000e+00, no recursion.
- Cell 1: unsloth_zoo's test_every_patched_moe_experts_class_has_lora_extractor
fails on transformers==4.57.6 because the MoE class surface unsloth_zoo
patches is newer. That's the real drift signal the matrix is supposed
to surface; the bug is upstream, not in CI. Keeping it as-is.
Per-step `continue-on-error: true` added on every test step so a cell
running into one failure (like cell 1's MoE test) still runs the
remaining steps (test_apply_fused_lm_head, static checks, runtime patch
ledger, tiled MLP, llama-cli smoke). The job-level continue-on-error
remains.
Drop `pip install --upgrade 'transformers>=4.51,<5.5'` and
`'trl>=0.13,<1'` in the static-check steps -- those upgrades would
override the matrix-selected versions and defeat the matrix's purpose.
The static checks now use whatever versions the runtime-deps step
installed for that cell.
