OTTO v5.1.0-beta: Score Push — Transport, Simulation, TUI

What's New in v5.1.0-beta

WhatsApp Outbound Transport

• WhatsAppTransport class using httpx + Meta Graph API v21.0
• Auto-detected from env vars in otto watch --schedule
• sender_phone field on Commitment model for round-trip tracking

Deterministic Simulation Engine

• otto simulate command exercises the full UCB1 -> trail -> routing pipeline
• SHA-256 based PRNG (no random module) — PYTHONHASHSEED-independent
• 10 scenarios covering all 7 modes, configurable cycles and seed

TUI Dashboard

• otto tui command (optional: pip install otto[tui])
• Textual-based terminal UI showing commitments, cognitive state
• Keybindings: d (done), p (park), r (refresh), q (quit)

Production Hardening

• /health endpoint for load balancers and monitoring
• Dockerfile with healthcheck
• SQLite-backed rate limiter (survives process restarts)
• HMAC validation warning on startup when WHATSAPP_APP_SECRET not set
• UCB1 exploration constant tuned to 0.5 (safety-conservative)

Design Gap Fixes (from v5.0 code review)

• PlasticityWindow persisted in SQLite (no longer ephemeral)
• mode_outcomes table auto-prunes entries older than 30 days
• otto nuke clears learning data (trails + outcomes + plasticity)
• Redirector mode included in UCB learning via BURST_DETECTED signal

Stats

• 636 tests passing (580 core + 56 agent)
• 22 files changed, 2,211 insertions in score push commit
