v6.66.1

v6.66.1 — CI/release plumbing fix

Patch-level release that fixes binary-release multi-target builds.

Fixed

• binary-release.yml: explicit rustup target add against the workspace-pinned toolchain so x86_64-unknown-linux-musl native cross-compiles don't fail with "can't find crate for core" mid-build (#200).
• binary-release.yml: drop provable-contracts path = ".." Cargo dev-dependency override so aarch64 cross builds resolve the dep purely from crates.io (#201). cross v0.2.5 mounts only the workspace dir into its Docker container — sibling-of-workspace path deps were unreachable inside the cross image.

Notes

• v6.66.0 release captured x86_64-unknown-linux-{gnu,musl} binaries, but aarch64 builds failed (path-dep override unreachable inside cross). v6.66.1 is the first tag where the corrected workflow + corrected Cargo.toml line up to produce all four Linux tarballs.
• No source-level changes from v6.66.0; CI/release plumbing only.

• 80 corpus failures eliminated (97.0 → 97.5 A+)
• Lexer panic on bare heredoc
• Pipe-in-condition parser (#133)
• Dynamic array indexing with runtime variables
• For-in array expansion

Added

v6.61.0 — 2 P0 Transpiler Fixes + 14,712 Corpus Entries

Highlights

Transpiler Bug Fixes (P0)

Two critical correctness bugs fixed in the Rust-to-Shell transpiler:

1. Return-in-loop: return expr inside while/for/match bodies within functions was emitting debug format strings (Arithmetic { op: Add, ... }) instead of shell arithmetic ($((expr))). Root cause: loop/match bodies were not propagating function-context awareness for return handling.

2. Match-in-let: let x = match y { 0 => a, 1 => b, _ => c } was producing x='unknown' instead of a proper case statement with per-arm assignments. Root cause: the parser represents match-as-expression as Expr::Block([Stmt::Match{...}]), which had no handler in convert_expr_to_value.

Both bugs were silent — the transpiler succeeded but generated incorrect shell code.

Corpus Expansion

• 14,712 total entries (13,397 Bash + 695 Makefile + 620 Dockerfile)
• V2 Score: 97.5/100 (A+), 0 failures
• 107+ CLI subcommands for corpus analysis, quality gates, and convergence tracking

New Example

cargo run --example transpiler_demo — 7 self-verifying demonstrations:

• Basic functions with return values
• Nested function calls: f(g(h(x)))
• Match expressions in let bindings
• While loops with early return
• Match inside loops (combined pattern)
• Recursive functions (fibonacci)
• Multi-function programs (gcd/lcm)

Documentation

• New Transpiler chapter in The Rash Book (overview + corpus testing)
• Updated README with current quality metrics
• Updated book version references
