nx_pattern_emit11.nx -- PATTERN EMITTER: PREDICTOR_CODER (shape 16 -- grown from the NV1 FLAC-class LPC rung, the media-codec core NO covered pattern could author; that build named exactly the three concepts this emitter closes): predict next sample = FIXED linear comb of the last o samples (binomial coeffs, o = 0..3: 0 | p1 | 2p1-p2 | 3p1-3p2+p3), exact integer math zigzag signed residual -> unsigned (r>=0 -> 2r, r<0 -> -2r-1), exactly invertible invert restore(residuals(x)) == x BIT-EXACT (the lossless law) and an out-of-range reconstruction is REFUSED at decode (-2) -- the NV1 tamper-evidence doctrine Authored fns: <name>_pred(p1,p2,p3); <name>_residuals(x,n,u) -> n-o residuals (-1 if n<=o); <name>_restore(u,m,w,x) -> sample count or -2 out-of-range (bound vmax BAKED, rule 11). EMIT-TIME RAIL (the PID-emitter discipline): the emitter RUNS the full round-trip on a synthetic vector with its own math BEFORE writing any file -- a spec whose round-trip is not bit-exact is REFUSED. Param rails: order outside 0..3 or vmax outside 16..65535 -> REFUSED. Test KATs (residual values, tamper push, n<=o refusal) computed BY the emitter at emit time. LAWS: struct-free, integer-only, flat ifs, no &&/||, <=6 args per func. license_tier: ORIGINAL
