Cute Verify

Run all four checks, then fix any issues:

• Lint — ./lint.sh (Ruff + Pyrefly).
• Default test suite — pytest test/ -n4 -q --tb=line.
• CuTe test suite — HELION_BACKEND=cute pytest test/ -n4 -q --tb=line.
• Code review — spawn an Opus-class general-purpose subagent with the diff (git diff HEAD~ covers staged + uncommitted, or pick the right scope for the situation).

Parallelism: Run lint and the code-review subagent in parallel with the test suites is fine, but never run the two pytest suites simultaneously — both use -n4 and would put 8 workers on the GPU, causing OOMs and flaky failures. Run pytest suites sequentially.

Review subagent prompt (use subagent_type: general-purpose, model: opus):

> Review git diff HEAD~ in /data/users/jansel/helion. Focus on:

> - Correctness: wrong logic, missed edge cases, broken invariants.

> - Simplification: redundant code, layers that could collapse, premature abstractions.

> - Hacky things: ad-hoc workarounds, type-casts that hide bugs, magic constants without comments, stub APIs that aren't really plumbed.

> - Disabled / regressed coverage: tests that were deleted or @skiped without an equivalent replacement; functionality that silently lost a code path (e.g. an if branch removed without checking callers).

>

> Report concrete file:line issues. Under 400 words. Say "LGTM" plainly if clean.

If any check fails, fix the underlying issue (don't suppress it) and re-run only that check. Repeat until all four are clean.

Final report:

| Check | Result |

| ----- | ------ |

| ./lint.sh | clean / N issues fixed |

| pytest (default) | <pass>/<skip> |

| pytest (cute) | <pass>/<skip>/<xfail> |

| code review | LGTM / <N> nits applied |

Notes:

• Don't pass HELION_AUTOTUNE_EFFORT=none to a full suite run; it changes execution paths and breaks tests. Use it only for targeted local iteration.
• Use pytest -ra if a skip count looks suspicious — it prints skip reasons.
