nx_swarm_tile.nx

nx_swarm_tile.nx -- SWARM FABRIC chunk EXECUTOR (SF-R3 real-artifact): a sovereign, embarrassingly- parallel image generator. Each "chunk" = a horizontal BAND of a fixed-point Mandelbrot render; bands are INDEPENDENT (no cross-tile state) = the exact workload class the operator named (3D render / Monte Carlo / brute-force). The job engine (nx_swarm_job) stays GENERIC -- it leases opaque chunk ids; THIS organ turns chunk id -> real pixels; a DRIVER wires place->lease->render->complete->assemble (rule 9). Proves the north-star "generate an image by combining/parallelizing across the fabric" with REAL output (was SIMULATED in the SF-R3 gate). When remote workers join, the SAME job engine dispatches the SAME bands to them -- distribution is placement, already proven; this is the executor + assembler. render <W> <H> <ntiles> <tile_id> <outdir> -- render band tile_id -> outdir/tile_<id>.raw (RGB) assemble <W> <H> <ntiles> <outdir> <out.ppm> -- stitch bands in order -> a real P6 PPM image [gate] -- self-gate: determinism + structure + coverage + size Fully integer (Q16 fixed-point escape-time) -> bit-identical across any device (the sovereign EXCEED axis: float raster is non-deterministic across hardware). outdir: bare name or under /tmp/. license_tier: ORIGINAL
