[codex] remove init stages in qwen3 scope3

[high-cloud]

What changed

Remove the redundant initialize stages in examples/models/qwen3/qwen3_32b_decode_scope3.py and renumber the remaining stage annotations.

Why

This scope writes each tile block directly before use, so the extra initialize stages are unnecessary. The stage numbering should stay aligned with the reduced pipeline.

Impact

The scope3 example is easier to read and its stage comments match the actual execution flow.

Versions

• pypto: 066b194 (main)
• simpler: d62341b (stable)

Validation

• python examples/models/qwen3/qwen3_32b_decode_scope3.py

📝 Walkthrough

Walkthrough

Removed explicit zero-initialization of resid1_tile in two parallelized auto_incore stages, deferring its population to the residual-add stage. Updated stage numbering comments to reflect the shifted stage mapping after initialization block deletions.

Changes

Cohort / File(s)	Summary
Residual Tile Initialization Refactoring examples/models/qwen3/qwen3_32b_decode_scope3.py	Removed explicit zero-initialization blocks for resid1_tile in two parallelized auto_incore stages; deferred population to residual-assemble stage. Renumbered computation stage labels (Stage 1/2/3/4/5/8&9 → Stage 0/1/2/3&4&5/6&7) to reflect shifted mapping. No changes to function signature or core mathematical operations.

Poem

🐰 A rabbit hops through tiling chains,
Removing zeros, no more stains!
Now residuals wait for their assembly call,
Deferred with grace—the stages heed it all! ✨

Code Review

This pull request simplifies the scope3 function in qwen3_32b_decode_scope3.py by removing redundant initialization stages for the resid1_tile and mlp_tile accumulators. The subsequent processing stages have been renumbered to reflect these changes. I have no feedback to provide.

66-66: Consider using ASCII x for the multiplication symbol.

Ruff flags the Unicode × (MULTIPLICATION SIGN) as ambiguous. While readable, using ASCII x would silence the lint warning.
