nx_converge.nx

nx_converge.nx -- CLI/MCP surface for the retention convergence controller. All control logic lives in nx_converge_lib.nx, which the GATE imports too, so the thing that ships and the thing that is graded are the same code. VERBS plan <target> <tol> -> the FIRST denoise probe to render, plus the step budget. Costs zero GPU. next <target> <tol> <lo> <hi> <probe> <measured> <steps_used> -> the next probe (or DONE) given what the ruler measured for the last render. STATELESS: the bracket travels in the arguments, so an agent/workflow can drive one render at a time and the whole search is replayable from its transcript. simulate <target> <tol> -> run the controller to completion against the oracle built from REAL measured retention, printing the full trajectory. This is how you see the step count before spending GPU. selftest expect_exit: 0 license_tier: ORIGINAL
