nx_emit.nx

nx_emit.nx -- WRITING arc, rung W-ING-4: turn extracted scene DATA into the two strings the downstream consumers actually want: em_image_prompt -> a bare comma-tag prompt for IMAGE-GEN ("mira, garden, dusk") em_companion_ctx -> a labeled context line for the COMPANION LLM ("present: mira | desc: garden, dusk | dialogue: 1") Both are deterministic assemblies over (a) the roster names present in the scene and (b) the descriptor-lexicon terms present in the scene -- reusing the WHOLE-WORD counter from nx_ingest (DRY). CONTENT-AGNOSTIC: the operator's lane supplies the real roster + lexicon (incl. outfit/MPL + register terms); the engine emits the prompt/context identically for any register. It never invents a tag -- only what is present in the text appears (proven by the empty-scene neg-control in the gate). Pure integer, NO syscalls. Caller owns dst (>= a few hundred bytes is ample). license_tier: ORIGINAL module: nishi-core.write.emit depends: nishi-core.write.ingest capability: WRITE_PROMPT_EMIT
