+# Analysis Verification Checklist
+
+**Date:** 2026-01-01  
+**Status:** ✅ COMPLETE
+
+---
+
+## Problem Statement Requirements
+
+### ✅ Requirement 1: Core Flows Executed in Local Claude Code Session Processes
+
+**Documented in:** ARCHITECTURE_ANALYSIS.md § 1
+
+- [x] Identify and list flows that run locally
+  - Session Discovery Flow (§ 1.1)
+  - Session Parsing Flow (§ 1.2)
+  - Message Assembly and Ordering Flow (§ 1.3)
+  - Complete Ordered Message History Derivation (§ 1.4)
+
+- [x] Focus on core flows for determining, retrieving, and assembling session data
+  - Initial user request handling ✓
+  - Primary agent replies ✓
+  - Tool calls ✓
+  - Tool responses ✓
+  - Other messages, metadata, and information ✓
+
+- [x] Explain step-by-step how flows locate session data
+  - File scanning with glob patterns (Line 358)
+  - Filtering logic for agent files and empty sessions
+  - Summary extraction from JSONL/JSON files
+  - Sorting by modification time
+
+- [x] Explain how they derive complete ordered message history
+  - Temporal ordering via timestamps
+  - Conversation grouping by user prompts
+  - Turn-based model (user → assistant → user)
+  - Tool result lookup table construction
+  - Message pairing and rendering
+
+---
+
+### ✅ Requirement 2: Connecting the Main Agent to Sub-Agent Activity
+
+**Documented in:** ARCHITECTURE_ANALYSIS.md § 2
+
+- [x] Explain how system identifies sub-agent messages
+  - **Current State:** No sub-agent support (Line 359-360)
+  - Agent files are explicitly excluded
+  - All messages treated as single-agent conversation
+
+- [x] Describe association with main agent
+  - N/A - No sub-agent hierarchy
+  - Future considerations documented (§ 2.5)
+
+- [x] Explain tool call/response linking
+  - ID-based pairing system (§ 2.2)
+  - `tool_use_id` field references tool call `id`
+  - Lookup table construction (Lines 2092-2105)
+  - Paired rendering to avoid duplicates
+
+- [x] Describe IDs, references, parent-child relationships
+  - Tool IDs: Unique identifiers (e.g., "toolu_001")
+  - Tool use ID references in results
+  - No parent-child relationships (no sub-agents)
+
+- [x] Explain event sequencing
+  - Temporal ordering via timestamps (§ 2.4)
+  - File order preserves chronology
+  - Turn-based flow: Prompt → Response → Tool Results → Response
+
+---
+
+### ✅ Requirement 3: Object Schemas (Complete Specification)

+
+---
+
+### ✅ Requirement 4: Proposed Componentization Plan
+
+**Documented in:** ARCHITECTURE_ANALYSIS.md § 4
+
+- [x] Propose component/module separation
