# v0.12.0 Release Notes

This update (`v0.12.0`) delivers a structural reinforcement resolving stream duplication/overlays during prompt resumes, and introduces highly requested predictive control surface sustainability.

## 📊 New Features

### 1. Predictive Adaptive Actions Console
Injected a **Predictive Adaptive Controller** design directive into the system prompt context.
* **Continuity Architecture**: Micro-views (`<iframe>`, `<richui>`, or HTML embeds) are now recognized by the LLM as Dynamic Operational State machines, preventing the panel from going stale/unclicked between new conversational turns.
* **Physical Isolation & Persistence**: The Pipe now pre-emptively initializes an **`interactive_controls` state table** in the per-session `session.db` workspace database. The LLM can use its `sql` tool to track continuous actions reliably.
* **Selective Recall**: Evaluates next-turn likelihoods natively to include *only* relevant unclicked control bars into the latest response stream so you don't scroll back up to click.

## 🛠️ Bug Fixes

1. **Stream Overlap Deduplication**:
   * Resolved concurrent string duplication overlay bugs on `assistant.message_delta` frames (e.g., repeating prefixes) by enforcing strict conservative overlap trimming rules during turn resumptions.
2. **TTFT Fine-grained Profiling**:
   * Deployed micro-segment timers separating local subprocess setups (~1.6s) from cloud network intervals (~2.3s) for full accounting calibration data readout directly in browser consoles.
3. **Eliminate Redundancies**:
   * Cut redundant secondary heavy `_parse_mcp_servers()` loops inside session resume packager for slight performance speed improvements.
