nx_swarm_sim.nx

nx_swarm_sim.nx -- deterministic swarm simulator + download engine (bits-up, replayable). module: nishi-core.torrent.swarm_sim depends: nx_stream_picker.nx (-> nx_piece_manager), nx_syscalls.nx capability: CORE_COMPUTE wired_status: FULLY_WIRED The "session loop" made TESTABLE: a discrete-round model that drives the REAL picker (nx_sp_stream_pick / nx_pm_rarest) and the REAL endgame logic (nx_sp_in_endgame) against a scripted swarm of honest / stalling / lying peers. Because every decision is integer and the peer script is fixed, the whole download REPLAYS bit-for-bit -- the determinism exceed no mainstream client has, here turned into a measurement instrument: a decision-trace hash that must be identical across runs. This is also the substrate the benchmark grades on (adverse-swarm completion, endgame value, streaming-to-playable). It is a SIMULATOR, not a live client -- it measures the selection brain, honestly named as such; the live socket loop is the named next rung.
