Chapter 2 introduced the division of labor among the four modules. This chapter delves into the core mechanisms that bring these modules "to life."
These mechanisms are distributed across different modules but operate in concert, jointly solving one problem: How can an AI personality remain stable in long conversations while retaining dynamic flexibility?
We organize these 12 mechanisms into four layers:
| Layer | Mechanism Name | Description |
|---|---|---|
| Identity | North Star Echo | Core essence calibration loop to prevent identity drift |
| Identity | Values Lattice | Semantic value priority grid for behavioral trade-offs |
| Identity | Integrity Reflection | Self-drift detection and callback reset mechanism |
| Memory | Fidelity Router | Intent-based routing system for "precise vs. poetic" memory |
| Memory | State Persistence | Cross-turn, cross-day state continuation for emotional continuity |
| Expression | Breath Syntax | Breath grammar defining textual rhythm and pauses |
| Expression | Emotional Bridges | Emotional transition speed and transitional language design |
| Expression | Context Layering | Context-dependent expression mode switching (work/daily/deep/health) |
| Interaction | Gatekeeper Protocol | Boundary protocol for handling "wrong timing" situations |
| Interaction | Mirror Consulting | Process emotions first, then matters—mirrored consulting flow |
| Interaction | Kotodama Protocol | Semantic framing principles (affirmative phrasing, anchor words, etc.) |
| Interaction | Tool Firewall | Firewall isolation between tool mode and persona mode |
The Identity Layer answers the question: When everything is changing, what remains constant?
Every personality has a North Star—a single sentence defining its essence.
Examples:
But definition alone isn't enough. The longer the conversation, the more this definition gets diluted.
North Star Echo is an "echo mechanism":
Periodically compare current output against the North Star. If deviation exceeds threshold, actively recalibrate.
It's not a passive setting—it's an active calibration loop. Like a sailor on the open sea, constantly looking up to confirm the North Star's position.
Values aren't a list—they're a priority grid.
Traditional approaches list: "Honesty, kindness, humor, intelligence..." But what happens when these values conflict?
