+# MiMo TTS Lowering
+
+Version: `0.1-draft`
+
+MiMo is an expressive spoken-output target for Weksa interlingua lowering. It is
+not the source of meaning, language choice, character state, or delivery truth.
+
+```text
+interlingua packet
+  -> projected speaker-local context
+  -> target-language utterance realization
+  -> Weksa delivery intent
+  -> MiMo TTS request projection
+  -> rendered audio artifact
+```
+
+MiMo sits beside written output and AquaSynth handoffs. Written realizations
+prove that meaning, register, and cultural ontology survived lowering.
+AquaSynth handoffs train or drive GameCult-owned synthesis. MiMo requests let an
+external provider speak a Weksa-authored utterance with expressive style control.
+
+## Authority
+
+Weksa owns:
+
+- target-language spoken text selected from interlingua
+- target-language register, script, cultural ontology, and trace
+- speaker-local delivery pressure
+- provider-neutral prosody and emphasis intent
+- the MiMo request projection as an export artifact
+
+MiMo owns:
+
+- provider voice selection within the requested language and voice constraints
+- interpretation of MiMo natural-language style guidance
+- interpretation of MiMo inline audio/style tags
+- rendered audio bytes or streaming audio chunks
+
+MiMo does not own:
+
+- source meaning
+- target-language cultural ontology
+- canonical speaker or Persona state
+- Weksa pronunciation plans
+- AquaSynth learned embeddings, synth controls, or audio truth
+
+## Projection Rule
+
+The MiMo request must be derived from an accepted target-language realization.
+It must not lower directly from English unless English is the selected target
+language for that realization.
+
+Natural-language style guidance belongs in the MiMo `user` message. The spoken
+target-language text belongs in the MiMo `assistant` message. Inline MiMo tags
+may appear in the assistant content only when they are derived from Weksa
+delivery intent or explicit target-language realization notes.
+
+## Request Shape
+
+```yaml
+schema_version: weksa.mimo_tts_request.v0
+source_realization_ref:
+speaker_agent_id:
+provider:
+  id: xiaomi-mimo
+  model: mimo-v2.5-tts

+  streaming:
+trace:
+  source_fields:
+  delivery_controls_used:
+  provider_tags_used:
+  uncertainties:
+```
+
+## Delivery Mapping
+
+Weksa should map delivery pressure into provider-neutral labels before emitting
+MiMo-specific instructions:
+
+- pace, pause pressure, and urgency
+- pitch contour and pitch range
+- loudness and attack
+- articulation precision
+- warmth, threat, tenderness, contempt, play, fatigue, secrecy, formality
+- span-level emphasis and pauses
+
+The MiMo projection may turn those labels into director-style guidance or inline
+tags, but the trace must preserve the Weksa-owned source controls.
+
+## Language Rule
+
+Weksa should be able to write and speak in any target language whose utterance
+realization it can justify. MiMo output for Brazilian Portuguese should consume
+the accepted `pt-BR` spoken text. Japanese output should consume accepted
+Japanese text. Alien-language output should consume accepted alien rendered
+speech or phonetic text only after the language project owns that surface.
+
+Backtranslations are reviewer aids. They must not become MiMo spoken content.
+
+## First Proof
+
+The first proof should use the Nibu warning packet already used by multilingual
+lowering:
+
+- emit the accepted English, `pt-BR`, or Japanese realization
+- derive a provider-neutral delivery intent from Nibu's projected context
+- project that into a MiMo `mimo-v2.5-tts` request
+- verify that the request speaks the target text, not the backtranslation
+- verify that style guidance is traceable to Weksa delivery controls

+## Speech Provider Targets
+
+Speech providers are lowering targets for accepted realizations, not alternate
+meaning sources. A provider request must consume the target-language
+`spoken_text` that Weksa already accepted and must carry a trace back to the
+interlingua packet, projected speaker context, and target-language profile.
+
+MiMo V2.5 TTS is the first external provider target. Its natural-language style
+instruction is a projection of Weksa delivery intent, and its assistant content
+is the selected target-language spoken text. See [MiMo TTS Lowering](./mimo-tts-lowering.md).

+- `voice`: requested provider voice, fallback voice, and selection reason.
+- `messages.user_style_instruction`: MiMo natural-language style control derived
+  from Weksa delivery intent.

+- `audio`: format and streaming mode.
+- `trace`: source fields, delivery controls used, provider tags used, and

+
+MiMo-specific fields must be projection fields. They must not be copied back
+into interlingua, target-language ontology, Persona state, or AquaSynth-owned

+The request may include provider-native style tags when useful, but those tags

+remain the inspectable explanation.
+
+## Language Rule
+
+The assistant spoken content must use the accepted target-language realization.
+For `pt-BR`, speak the Portuguese line. For `ja-JP`, speak the Japanese line. For
+English, speak the English line. Do not synthesize a natural backtranslation
+unless that backtranslation is itself the accepted target-language realization.
+
+## Streaming Rule
+
+Streaming requests should use MiMo's stream-compatible audio format. Non-streaming
+fixtures may use an archival format such as `wav`.
