# Original formatter dispatch integer string character and literal composition RE-815. Reproduce with `python3 scripts/analyze_qvm_formatter.py`; focused validation: `cargo xtask test-group formatter`. [Machine report](qvm-formatter.json). 55 complete source formatter fixtures cover d/i/p, string width/precision/null handling, zero and left padding, escaped percent, raw characters, unknown conversions and mixed arguments. Independent parsing/byte arithmetic verifies result length and terminal NUL, including embedded character NUL. Float formatting, malformed/trailing formats and unsafe vararg/padding domains remain excluded. Original executable/native runtime and complete Linux/macOS Rust/Bevy/Solari acceptance remain unverified.
