"""Voice Self-Improvement Engine — every conversation makes the model smarter.
After each Jarvis conversation:
1. Store the full voice transcript as a linked context in the recursive link graph
2. Extract conversation patterns (question types, response styles, user preferences)
3. Share learnings via universal recursive link to peer instances
4. Accumulate conversations into a training buffer
Online learning: When the model is idle (no active conversation for 60s):
1. Pull recent conversations from the training buffer
2. Run a lightweight fine-tuning pass (a few gradient steps)
3. Update weights in-place using SplitBit quantization
4. Clear the buffer — model is now slightly smarter
Self-talk training: Jarvis can talk to itself when idle:
1. Generates a question based on recent conversation topics
2. Generates a response to its own question
3. Scores the interaction (coherence, conciseness, helpfulness)
4. Keeps high-scoring pairs as training data, discards low-scoring
5. This creates unlimited synthetic training data for free
Confidence tracking: Model tracks its own confidence per response.
Low-confidence responses trigger more self-talk practice on that topic.
