Re-review at 7286d320. -013 (Medium, testing): the managed FOCAS/2 wire-decode layer
(BuildPdu/ParseResponseBlocks, incl. cnc_getfigure stride) had zero byte-level tests; added
15 (no decode bug found). -014 (spindle-load truncation heuristic) deferred bench-gated.
Note: runtime read path is now pure-managed TCP (no P/Invoke except the probe handshake).
