-- Tool Execution: Controlled via `presentAssistantMessage.ts` and individual tool handles like `WriteToFileTool.ts`.
-- Prompt Logic: The system prompt is constructed in `src/core/task/Task.ts`.
-- Governance Layer: We have initialized a `.orchestration/` sidecar for intent-traceability.
-- Integration Goal: We will implement a Pre-Hook in `WriteToFileTool.ts` that validates actions against `.orchestration/active_intents.yaml`. -->

 ## 3. Intent-Code Gap Analysis
 
 Standard Git tracks "What" changed but lacks the "Why." By using a sidecar orchestration layer, we map every Abstract Syntax Tree (AST) change to a specific Requirement ID. This prevents "Context Rot" where agents lose track of architectural constraints during long-running tasks.
+
+# Architectural Design Report
+
+## 1. The Intent-First Protocol (Two-Stage State Machine)
+
+The core of this implementation is a move away from "Vibe Coding" towards a governed, stateful interaction. I have architected a Two-Stage State Machine for every user request:
+
+**Stage 1: The Reasoning Intercept (The Handshake):** The agent is no longer permitted to generate code immediately. It must first analyze the request, identify a valid intent_id from the governance sidecar, and call the select_active_intent tool.
++1
+
+**Stage 2: Contextualized Action:** Only after the "Handshake" is successful and the context is injected can the agent proceed to use destructive tools like write_to_file or execute_command.
++1
+
+## 2. The Deterministic Hook (Gatekeeper Architecture)
+
+To ensure compliance, I implemented a Deterministic Hook System that acts as a strict middleware boundary:
++1
+
+Pre-Hook Implementation: In WriteToFileTool.ts and ExecuteCommandTool.ts, I injected a gatekeeper check at the start of the handle method.
+
+Verification Logic: This hook verifies the presence of a global active intent flag. If the agent attempts a file modification without a validated "checkout," the hook blocks execution and returns a formal governance error: "You must cite a valid active Intent ID".
+
+Fail-Safe: This ensures that the architecture enforces the rules, rather than relying on the LLM's "best effort" to follow instructions.
+
+## 3. Context Engineering (Dynamic Injection vs. Context Rot)
+
+Traditional AI IDEs suffer from "Context Rot" by dumping entire file trees into the prompt. This implementation solves this via Dynamic Context Injection:
++1
+
+**Sidecar Pattern:** All architectural constraints and business intents are stored in .orchestration/active_intents.yaml.
++1
+
+**On-Demand Context:** When select_active_intent is called, the system reads the YAML and constructs a targeted <intent_context> XML block.
+
+**Traceability:** This ensures the agent only operates within its "owned_scope" and respects the "acceptance_criteria" defined in the sidecar, maintaining a high signal-to-noise ratio in the context window.
