Leaf (stdlib only). Six probes per worklog/rq6-selftest-probes.md (RQ6): tty (the grid gate: stdin-isatty, RQ8) · size (TIOCGWINSZ, 10x50 min) · kernel (TIOCSTI on a throwaway pty — never the real tty, spec 5.3) · shell (the ACTUAL shell = the parent's /proc//comm, $SHELL fallback, spec 5.4) · relay (sshj-relay, REQUIRED whenever TIOCSTI is refused; the /bin/bash child sub-check rides along, spec P5 note) · python (floor 3.8). run(ver) prints the table to stdout (2-space indent, 4-char status col, 2-space gap, 9-char name col — exactly the spec section 4 sample), one degrade message per WARN/FAIL to stderr, and returns the exit code: 0 all OK · 1 warnings only · 2 any FAIL. No global state, no network, no writes.
