docs(t27o): golden candidates -- the 81 Rust files that convert whole, ranked by the hand lines a port deletes (Closes #11149) - #11155
Merged
Conversation
…, ranked by the hand lines a port deletes (Closes #11149) Analysis only, step 4 of #9000: no Rust is deleted and no spec is added. 85 of the 1,388 swept files have every fn converted; 4 refuse a struct or an item and are not whole, one of the 81 is a test-only file. The 80 ranked rows hold 3,006 hand lines (0.69% of the swept lines); 70 of them are 17-32 line scaffold stubs with no caller, and 73 sit in trios crates the workspace does not build. Per row: lines (non-blank, cfg(test)), fns, tests, public items, callers, crate and workspace membership, t27c test-report (all 85 exit 0), an oracle replay (all 85 pass), the gen-rust signature mapping against the original, and a verdict. 78 rows are PORTABLE-NOW (2,864 lines), SC-00 needs a caller change (Vec2::new becomes a free fn), rainbow-bridge lib.rs is NOT-NOW (a module hub whose 8 pub mod and 8 pub use the converter drops without a refusal). Seven rows delete at least 100 lines with every caller unchanged. The first one deliverable today is bootstrap/src/host/bitmask.rs (170 lines, one caller: two lines of host/mod.rs); a differential run of hand against generated code made 68,268 comparisons with 0 disagreements, and the own-language budget returns rc 0 for the port's numstat. trios has no generated root and no gate, so its rows are safe for callers but not yet deliverable.

…ted to 20-32 lines (Closes #11149) The callers column now starts with the number of files outside the row that name a public item (0 for the 70 scaffold stubs), and names the three files that use trios-rainbow-bridge. The scaffold stubs are 20-32 physical lines, not 17-32 (17 was the non-blank minimum). Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>

What
Analysis only, step 4 of #9000: which hand-written Rust files of our own repositories t27o converts whole, what a port would delete, and which of them a generated file replaces without changing a caller. One new file,
docs/now/2026-10-20-golden-candidates.md. No Rust is deleted and no spec is added.Closes #11149
Numbers
.rsfiles; 85 have every fn converted; 4 of those refuse a struct or an item and are not whole; 1 of the remaining 81 is a test-only integration test. 80 ranked rows, 3,006 physical hand lines (2,569 non-blank, 1,301 inside#[cfg(test)]), 0.69% of the swept lines.t27c test-report(all 85 exit 0, vacuous count per row), an oracle replay oftri t27o --check(all 85 pass), the gen-rust signature mapping against the original, and a verdict.SC-00,Vec2::newbecomes a free fn), NOT-NOW 1 (trios-rainbow-bridge/src/lib.rs, a module hub whose 8pub modand 8pub usethe converter drops without a refusal).Cargo.tomlmembers andCargo.lock)..rsfiles); all 8 are generated (trios-mesh/gen/rust), excluded.First candidate
Seven rows delete at least 100 lines with every caller unchanged (five CR-CHAT guards,
trinity_loss,bitmask). The first one deliverable today isbootstrap/src/host/bitmask.rs: 170 lines (96#[cfg(test)]), one caller (host/mod.rs, two lines),t27c test-report14/14 with 0 vacuous, oracle replay 25 tests pass with 95 asserts, a differential run of the hand file against the generated file made 68,268 comparisons with 0 disagreements, a#[path]mount of the generated file built in a simulated tree, and theown-languagebudget compiled from the base revision returns rc 0 for the port's numstat (+1 / -171 hand lines). trios has no generated root and no gate, so its rows are safe for callers but not yet deliverable.Checks run
