| # Port assisted progress with target meter feedback | |
| RE-1009. Focused validation: `cargo xtask test-group rust-assist-progress`. [Machine report](rust-assist-progress.json). | |
| Rust matches24 assisted progress cases, including f32 rounding, negative/wrapped elapsed time and completion. Target meter completion mirrors its result to the helper and preserves original nested effect order. Clock and target updates stage together, so invalid duration or late conversion errors leave both unchanged. Unit cases verify wrapped416-unit progress, zero mirroring at completion and rollback. | |
