From 1e20cfb34310cf6db25bffcbc4503ddf0d713ec5 Mon Sep 17 00:00:00 2001 From: Claude Date: Sun, 18 Oct 2026 23:46:08 +0700 Subject: [PATCH 1/2] t27o --check: t27b test judges first, t27c test-report only when t27b cannot (Closes #10525) On rust_std.t27 the two runners gave the same 10/10 verdict in 0.89 s (t27b) and 94 s (t27c test-report, through Zig). ledger.t27 now maps t27b's exit codes (cli/t27b/README.md) to the oracle outcomes it already defines: 0 pass and 1 fail are verdicts; 2 unsupported and 5 codegen limit are unsupported; 3 front end, 4 JIT/interpreter disagreement and any code outside the table are unknown. needs_reference() says when t27c must run. Two tests, one a negative control; a mutant that returns pass for an unknown code fails both. t27b 12/12, test-report 12/12 with 0 vacuous. cmd_t27o glue: 9 lines (mod line, the t27b run, the fallback message, the --check doc). gen/rust/tools/t27o/ledger.rs is gen-rust of the spec. Checked by hand: bitmask.rs --check now prints "t27b test exited 2 (unsupported), so t27c test-report judges instead"; the defects that run exposed are #10534.
