Adds two new strict-mode steps to the Core matrix to exercise the
dynamic file generation path in unsloth_zoo.compiler. Synthesized from
parallel design forks (cache_invariants + real-class + monkey-patch);
matrix expansion + monkey-patches stay as future PRs.
Step 1 -- "Compiler cache hygiene + source-rewriter invariants
(synthetic inputs)" -- 9 pytest cases on tiny synthetic source strings.
Covers higher_precision_softmax (basic + idempotent),
fix_rotary_embedding_dtype (no-op + active),
fix_attention_dtype_consistency (insert + idempotent),
convert_attention_masks_to_bool (rewrite + no-op),
create_new_function happy-path (versioning block / license header /
ast.parse / importlib re-import), and the UNSLOTH_COMPILE_OVERWRITE=0
forced-recompile-on-version-mismatch + matching-versions short-circuit
branches at compiler.py:947-963. Wall-time ~10-25s per cell.
Step 2 -- "Compiler real-class round-trip (llama / qwen3 / gemma3 +
SFT trainer)" -- runs unsloth_compile_transformers against actual
transformers modeling modules (llama, qwen3, gemma3) and TRL's
SFTTrainer. ast.parse + importlib + surface check on each generated
unsloth_compiled_cache/*.py. Includes a negative control test that
DISABLE=1 writes nothing. Hermetic per-pytest tempdir; skips legitimately
when transformers lacks a target model_type. Wall-time ~2-3 min per cell.
Both steps reuse tests/_zoo_aggressive_cuda_spoof.py and follow the
same auto-write-shim pattern as _zoo_apply_fused_lm_head_shim. The
job-level UNSLOTH_COMPILE_DISABLE=1 is popped inside the round-trip
shim so compilation actually fires there; restored on exit.
Plans at plans/compiler_cache_ci_fork_{a,b,c}.md (fork C's 3x3 matrix
expansion + NEEDS_PRECONDITION lift via monkey-patch are out of scope
for this PR but tracked there for follow-up).
