nx_pattern_emit12.nx -- PATTERN EMITTER: TEMPLATE_TABLE (shape 17). The Builder authors an HTML-fragment renderer CORE from a row table: each row = (kind:i64, open:*u8, mid:*u8, close:*u8, raw:i64). The authored <name>_one(kind, payload, plen, out, cap) emits open + payload + close; raw=0 payloads are ESCAPED via the gated hs_escape (the render-boundary law), raw=1 payloads are inserted verbatim (caller pre-sanitized rich text -- the sanitize-on-WRITE law); a non-empty mid makes the row TWO-SLOT (payload split at the first '|', both slots through the same mode, the <img src|alt> shape). Unknown kind -> -1 (refused, never silently coerced). The table is DATA (rule 11): no per-kind markup lives anywhere but the table. Test emission derives byte-exact KATs from the table itself (expected strings concatenated AT EMIT TIME), plus an escape KAT on the first escaping row and a mechanically-derived unknown-kind refusal. This is the CMS block-renderer shape (also nav menus, breadcrumbs, OG/meta tag lists). Extends the emit1-11 family. LAWS: struct-free, integer-only, flat ifs, no Claude core logic in the AUTHORED module. license_tier: ORIGINAL
