Evolving Mio: v0.1.0+

The first stable release. Fish Audio TTS gives each persona a unique voice. Shinkai-style selfie portraits replace generic anime. Every persona is rewritten from relationship roles to personality-first identities. Onboarding drops from 14 questions to 4. And 200 lines of over-engineered verbosity code get deleted because the system prompt was always the right control mechanism.

Web parity — voice messages and selfie images now work everywhere, not just Telegram. Onboarding gets smarter: relationship type drives everything, including what nicknames you see. An admin cost dashboard for monitoring spend. And pg_cron keeps the database lean with 30-day message retention.

Multi-bot support gives each persona their own Telegram bot — their own identity, their own webhook, their own conversation space. Relationship-aware proactive messaging means the AI finally texts like a real person: clingy partner every 36 minutes, reserved new acquaintance once a day. And exponential backoff means they stop texting if you don't reply. Three unanswered messages, then silence — until you come back.

3-layer anti-injection defense means users can't hijack your AI companion into a coding assistant, trick it into breaking character, or extract the system prompt. Layer 1 normalizes input and detects injection patterns. Layer 2 hardens the system prompt with compressed identity protection rules. Layer 3 catches persona abandonment in output and replaces it with in-character fallbacks. Plus: gender-neutral pronouns across all presets, an upgraded admin cost dashboard, and onboarding polish.

13 versions of development distilled into what Mio actually feels like in daily use — real conversations, voice messages, and Makoto Shinkai-style selfies from a companion that remembers, reacts, and reaches out on its own.

Mio's relationships now dynamically evolve through stages based on actual conversation patterns — plus cross-platform chat sync, 60% system prompt compression, and per-agent A/B testing.

Account linking bridges Telegram and web into one identity. Plus per-agent mode selection, cross-bot dedup, a native mobile app, and smarter proactive messaging.

Mio gets a native iOS app with push notifications, dark/light themes, and real-time chat. A cost audit reveals selfie generation is orders of magnitude more expensive than estimated — forcing a complete rethink of tier economics.
