Overview
Role Focus: Living implementation evidence and constraint surface.
Primary Function: Provides actual naming, dependency, and behavior signals used to validate architecture choices.
Environment / Context: Evolving repository with mixed historical decisions.
Core Motivations
Professional Drivers: N/A (system actor).
Emotional or Cognitive Drivers: N/A (system actor).
Systemic Positioning: Source of truth for implementation reality.

Expectation / Need
Description
Information
Stable naming and boundaries
Benefits from clear vocabulary and modular contracts.
Interaction
Minimal disruptive refactors
Prefers proportional changes that preserve behavior confidence.
Support
Consistent architecture guidance
Needs docs that map to behavior and constraints, not class inventories.
Governance
Decision traceability
Should be explainable by linked architecture decisions.
Decision Authority
Constraint authority
Existing dependencies and behavior constrain feasible architecture choices.
Frustrations and Constraints
Pain Points: Architectural proposals that ignore current coupling and migration cost.
Trade-Off Awareness: Supports incremental modernization over all-at-once redesign.
Environmental Constraints: Legacy structures, partial test coverage, and operational commitments.
Behavioral Cues
Situation
Typical Behavior
Interpretation
Stable / Routine
Reinforces existing patterns
Existing structures bias future implementations.
Change / Uncertainty
Surfaces coupling hotspots
Reveals hidden constraints through breakage risk.
Under Pressure
Resists broad structural change
Favor targeted, reversible modifications.
Collaboration Preferences
Decision Style: Evidence-constrained.
Communication Style: Manifested through static structure, tests, and runtime behavior.
Feedback Expectations: Architectural proposals should cite concrete implementation evidence.
Design Impact
Affected By: Domain boundary choices, container ownership, and integration patterns.
Needs From Design: Migration-aware decisions with explicit implementation consequences.
Risk If Ignored: Expensive refactors and architecture drift.
Acceptance Signal: New architecture decisions can be implemented incrementally with low disruption.

Narrative Summary
The Project Codebase acts as the reality check for architecture ideas. It encodes
historical constraints and opportunities, and it rewards decisions that respect
incremental change. Architecture quality is reflected in how safely the codebase
can evolve.
