1// nx_ws_exceed_gate.nx -- WMS-R11: the MEASURED exceed-git scorecard (the no-wave proof). 2// 3// The [[feedback-no-wave-measured-exceed]] law: don't CLAIM we beat the incumbent -- MEASURE it with 4// real numbers. git is the measuring stick (the reference workstream/state tracker every engineer 5// knows): it gets crash-safety from (a) lock files that SERIALIZE writers (index.lock -- the loser 6// FAILS and must retry) and (b) the reflog that REBUILDS lost refs. This gate MEASURES the WMS's hard 7// numbers on the same two axes, head-to-head against the NAIVE baseline we actually execute (the 8// unprotected path = "what you get WITHOUT these rungs"), and states git's guarantee as the named 9// yardstick those numbers meet/exceed -- git is NOT run here (sovereign/no-bleed), so its column is a 10// by-design reference, never reported as measured. 11// 12// MEASURED dimensions (our execution, identical concurrent load each side): 13// DIM-A concurrent-write lost-update : NWORKERS write NPER distinct keys each. 14// WMS = ws_put_locked (R8 flock) -> expect retrievable == total (0 lost) 15// naive= ws_put_p (unlocked) -> expect retrievable < total (lost > 0) [the manifest RMW race] 16// DIM-B crash-recovery completeness : NWORKERS write NPER reflog transitions concurrently; 17// the derived registry is then LOST (wiped). 18// WMS = ledger_rebuild from reflog -> expect recovered == total (100%) 19// naive= no reflog / no rebuild -> expect recovered == 0 (everything gone) 20// 21// EXCEED CLAIM (precise, measured): the WMS hits git's atomicity + recoverability guarantees with 22// ZERO git dependency AND -- unlike git's index.lock -- EVERY concurrent writer COMPLETES (the flock 23// path serializes-and-finishes; it never refuses the loser). GREEN(0) iff the WMS side hits the 24// durable target on BOTH dims AND the naive baseline measurably FAILS BOTH (load-bearing + non-vacuous 25// measurement -- a number that proves itself).
