nx_pattern_emit10.nx -- PATTERN EMITTER: WIRE_MARKER (shape 15 -- grown FROM a measured race loss: race 4a runs the team's closest covered pattern, WIRE_TLV, against a JPEG marker stream and loses; THIS emitter closes exactly the three spec gaps that loss names): prefix every segment starts with a prefix byte (JPEG 0xFF) -- TLV has none standalone a TABLE of marker values with NO length field (SOI/EOI/RSTn) -- TLV has none terminator a marker after which entropy/wire data follows (SOS): count/find STOP there inclusive the 2-byte BE length INCLUDES itself (JPEG) -- TLV lengths exclude the header Authored fns: <name>_count(b,n) -> segments through the terminator, -1 = bad prefix/short/ len<2 REFUSED; <name>_find(b,n,m) -> content offset (standalone: after marker; lengthed: after length), -1 absent (or behind the terminator), -2 malformed. All spec values BAKED at emit time (rule 11). Test KATs computed by the emitter from a synthetic marker image it constructs to the same spec (count, two finds, absent, truncation + garbage refusals). REFUSAL RAILS: prefix outside 1..255, terminator listed standalone, standalone table empty or >12 -> spec REFUSED. Extends ..emit7(WIRE_TLV)/emit8/emit9. Covers B5's JPEG segment walk (SOF2 progressive incl.) + any prefix-marker wire format. LAWS: struct-free, integer-only, flat ifs, no &&/||, <=6 args per func. license_tier: ORIGINAL
