- Strict exit codes: cargo/python/go tests expect exact exit codes
instead of "any" (catches real regressions)
- Binary size limit documented: 8MB for ARM Linux VM vs 5MB x86 stripped
- --phase NaN guard: error message instead of silent no-op
- Verdict: 0 failures = READY, any failure = NOT READY (no more "minor issues" budget)
- rtk err exit code bug tracked in #846
