Add Cognitive Layer - The missing OS layer for AI-human collaboration

This is what AI collaboration should have been from day one. A comprehensive
cognitive layer that solves the fundamental problems of context loss,
information silos, and coordination chaos.

## Core Components

**Intent Graph** - Tracks WHY things happen
- Every goal, task, and decision has a rationale
- Relationships between objectives are explicit
- Context is never lost

**Semantic File System** - Files that know what they ARE
- Auto-classification based on content and purpose
- Semantic search (find by meaning, not just name)
- Auto-organization (no more downloads folder chaos)
- Files suggest where they belong

**Living Documents** - Self-updating documentation
- Code-aware: understands what code it documents
- Detects when code changes and docs are stale
- Can auto-generate from code
- Always in sync

**Context Engine** - Right information at the right time
- Provides relevant context based on current task
- Integrates intent, code, docs, and decisions
- Proactive intelligence (suggests next actions)
- Answers: "Why does this exist?" "What's related?"

**Agent Coordination Protocol** - Multi-agent collaboration that works
- Shared context via cognitive layer
- Clear task ownership and handoffs
- No duplicate work
- Conflict resolution
- Progress tracking

**Smart Documents** - OCR, templates, auto-formatting
- Extract text from PDFs and images
- Identify document types automatically
- ATS-friendly resume formatting
- Business plan templates
- Auto-filing based on content
- Template matching and application

## What This Solves

Traditional problems:
❌ Files in arbitrary folders
❌ Context lives in people's heads
❌ Docs get out of sync
❌ Multi-agent chaos
❌ Downloads folder anarchy
❌ Lost decisions and rationale

Cognitive OS solutions:
✅ Files organize by meaning and purpose
✅ Context is captured and connected
✅ Docs update themselves
✅ Agents coordinate cleanly
✅ Everything auto-organizes
✅ Every decision is recorded with WHY

```python
from cognitive import CognitiveOS

# Initialize
cog = CognitiveOS()

# Create a goal with rationale
goal = cog.create_goal(
    "Build user authentication",
    rationale="Users need secure access"
)

# Process a document (auto-classify, auto-organize)
cog.process_new_file("~/Downloads/resume.pdf")

# Get context for what you're working on
context = cog.get_context(task_id="current-task")
```

## Philosophy

This is how AI and data should have been handled from the start:
- **Semantic over Hierarchical**: Organize by meaning, not folders
- **Intent-Preserving**: Capture WHY, not just WHAT
- **Auto-Linking**: Related things connect automatically
- **Context-Aware**: System knows what you're trying to do
- **Agent-First**: Designed for AI-human collaboration

Combines the best of Notion + Asana + actual code awareness +
auto-organization + OCR + business planning + ATS-friendly formatting.

No more hoping the world doesn't catch on fire.
No more downloads folder chaos.
No more lost context.

This is the cognitive layer every OS should have had.

+# Cognitive Layer - BlackRoad OS
+
+## The Problem We're Solving
+
+Every day, agents and humans struggle with:
+- **Context fragmentation**: Information scattered across files, commits, docs, chats
+- **Intent loss**: We forget WHY decisions were made
+- **Document chaos**: Downloads folder anarchy
+- **Knowledge silos**: Related info doesn't connect automatically
+- **Coordination overhead**: Multi-agent/multi-human collaboration is messy
+
+## The Vision
+
+What if your OS actually understood what you're trying to accomplish? Not just files and folders, but **intent, context, and meaning**.
+
+## Core Components
+
+### 1. Intent Graph
+Tracks goals, decisions, tasks, and their relationships. Every action has a "why" attached.
+
+### 2. Semantic File System
+Auto-organizes based on content and purpose. No more "hope the world doesn't catch on fire" file management.
+
+### 3. Living Documents
+Documents that are code-aware, self-updating, and understand their relationship to your project.
+
+### 4. Context Engine
+Provides exactly the information you need based on what you're trying to do right now.
+
+### 5. Knowledge Weaver
+Automatically connects related information across code, docs, tasks, and decisions.
+
+### 6. Agent Coordination Protocol
+Multi-agent collaboration that actually works - shared context, clear handoffs, no duplicate work.
+
+### 7. Temporal Inspector
+Understand how your system evolved and why - time-travel for decision making.
+
+## Philosophy
+
+- **Semantic over Hierarchical**: Organize by meaning, not arbitrary folder structures
+- **Intent-Preserving**: Capture WHY, not just WHAT
+- **Auto-Linking**: Related things connect automatically
+- **Context-Aware**: The system knows what you're trying to do
+- **Agent-First**: Designed for AI-human collaboration from the ground up
+
+## Real-World Use Case: The Smart Document System
+
+Imagine a doc editor that:
+- Understands if it's a resume, business plan, technical spec, or meeting notes
+- Automatically makes it ATS-friendly if it's a resume
+- OCR scans and extracts structured data
+- Auto-files itself based on project/purpose
+- Links to related code, tasks, and decisions
+- Formats itself correctly for the target audience
+- Updates when linked code changes
+- Suggests relevant templates based on intent
+
+That's what we're building.

+# Cognitive OS - Usage Guide
+
+## Quick Start
+
+```python
+from cognitive import CognitiveOS
+
+# Initialize the cognitive layer
+cog = CognitiveOS(workspace_path=".")
+
+# Show current state
+cog.show_current_state()
+```
+
+## Core Concepts
+
+### 1. Intent Graph - WHY Things Happen
+
+The Intent Graph tracks goals, tasks, decisions, and their relationships. Every action has a "why" attached.
+
+```python
+# Create a goal
+goal = cog.create_goal(
+    title="Build user authentication system",
+    description="Add login, signup, and password reset functionality",
+    rationale="Users need secure access to their accounts"
+)
+
+# Create tasks under that goal
+task = cog.create_task(
+    title="Implement password hashing",
+    goal_id=goal.id,
+    rationale="Passwords must be securely stored"
+)
+
+# Make a decision and record WHY
+decision = cog.intent_graph.create_decision(
+    title="Use bcrypt for password hashing",
+    rationale="Industry standard, proven security, good performance",
+    alternatives_considered=[
+        "argon2 (newer but less battle-tested)",
+        "scrypt (more memory intensive)",
+        "pbkdf2 (older, slower)"
+    ]
+)
+
+# Link decision to task
+cog.intent_graph.link_nodes(decision.id, task.id, "related")
+```
+
+### 2. Semantic File System - WHAT Files Are
+
+No more "throw it in downloads and hope." Files organize themselves based on what they ARE, not arbitrary folder structures.
+
+```python
+# Process a new file
+metadata = cog.semantic_fs.index_file("~/Downloads/resume.pdf")
+
+print(f"Document type: {metadata.document_type}")
+# Output: Document type: resume
+
+# Get suggested location
+suggested = cog.semantic_fs.suggest_location("~/Downloads/resume.pdf")
+print(f"Should go here: {suggested}")
+# Output: Should go here: documents/career/resumes/resume.pdf
+
+# Auto-organize (actually move the file)
+cog.semantic_fs.auto_organize("~/Downloads/resume.pdf", dry_run=False)
+
+# Search semantically
+results = cog.semantic_fs.search(
+    "technical skills",
+    filters={'document_type': DocumentType.RESUME}
+)
+```
+
+### 3. Living Documents - Self-Updating Docs
+
+Documentation that understands code and updates itself.
+
+```python
+# Create API documentation from code
+doc = cog.doc_manager.generate_doc(
+    doc_type=DocType.API_REFERENCE,
+    code_file="src/auth.py",
+    output_path="docs/api/auth.md"
+)
+
+# Check if docs are out of sync
+out_of_sync = cog.doc_manager.check_all_docs()
+for doc in out_of_sync:
+    print(f"⚠ Needs update: {doc.file_path}")
+    # Auto-update it
+    doc.update_from_code(doc.code_references.pop())
+```
+
+### 4. Context Engine - Right Info, Right Time
+
+Get exactly the context you need based on what you're doing.
+
+```python
+# Get context for a task
+context = cog.get_context(task_id="task-123")
+
+# See what's relevant
+for item in context.get_top_items(10):
+    print(f"[{item.type}] {item.title} - relevance: {item.relevance_score}")
+
+# Get context for a file
+file_context = cog.get_context(file_path="src/auth.py")
+# Returns: related tasks, documentation, decisions, similar files
+
+# Get current context (what's happening now?)
+current = cog.get_context()
+# Returns: active goals, blocked tasks, recent files, stale docs
+
+# Query-based context
+query_context = cog.get_context(query="How does authentication work?")
+# Returns: relevant code, docs, decisions about auth
+```
+
+### 5. Agent Coordination - Multi-Agent Collaboration
+
+Multiple agents working together without chaos.
+
+```python
+# Register agents
+coder = AgentInfo(name="CodeWriter", role=AgentRole.CODER)
+reviewer = AgentInfo(name="CodeReviewer", role=AgentRole.REVIEWER)
+
+cog.agent_coordinator.register_agent(coder)
+cog.agent_coordinator.register_agent(reviewer)
+
+# Create a collaboration session
+session = cog.agent_coordinator.create_session(
+    goal="Implement user authentication",
+    description="Add login, signup, password reset"
+)
+
+# Assign task to coder
+cog.agent_coordinator.assign_task("implement-login", coder.id)
+
+# When coder is done, handoff to reviewer
+handoff = cog.agent_coordinator.create_handoff(
+    from_agent_id=coder.id,
+    to_agent_id=reviewer.id,
+    task_id="implement-login",
+    handoff_type=HandoffType.REVIEW,
+    message="Login implementation complete, ready for review"
+)
+
+# Reviewer accepts and reviews
+cog.agent_coordinator.accept_handoff(handoff.id, reviewer.id)
+# ... review happens ...
+cog.agent_coordinator.complete_handoff(handoff.id, result={"approved": True})
+
+# Get agent context (what should agent know?)
+agent_context = cog.agent_coordinator.get_agent_context(coder.id)
+# Returns: current task, pending handoffs, session info, task context
+```
+
+### 6. Smart Documents - OCR, Templates, Auto-Format
+
+Documents that understand themselves.
+
+```python
+# Process a resume with OCR
+doc = cog.doc_processor.process_document("~/Downloads/resume.pdf")
+
+# See what was extracted
+print(f"Name: {doc.structured_data.fields.get('name')}")
+print(f"Email: {doc.structured_data.fields.get('email')}")
+print(f"Skills: {doc.structured_data.fields.get('sections', {}).get('skills')}")
+
+# Format as ATS-friendly
+ats_content = doc.format_as_ats_friendly()
+# Saves a clean, ATS-compatible version
+
+# Create new document from template
+cog.doc_processor.create_from_template(
+    DocumentTemplate.MEETING_NOTES,
+    "meeting_2024_01_15.md",
+    data={'date': '2024-01-15'}
+)
+
+# Process business plan
+biz_plan = cog.doc_processor.process_document("business_plan.pdf")
+print(f"Executive summary: {biz_plan.structured_data.fields.get('executive_summary')}")
+```
+
+## Complete Workflow Example
+
+Here's how it all works together:
+
+```python
+from cognitive import CognitiveOS, AgentRole, DocumentTemplate
+
+# 1. Initialize
+cog = CognitiveOS(workspace_path="~/projects/my_startup")
+
+# 2. Create a business goal
+goal = cog.create_goal(
+    title="Launch MVP by Q2",
+    description="Build and ship minimum viable product",
+    rationale="Need to validate product-market fit with real users"
+)
+
+# 3. Create tasks
+task1 = cog.create_task(
+    "Write technical specification",
+    goal_id=goal.id,
+    rationale="Team needs clarity on what to build"
+)
+
+task2 = cog.create_task(
+    "Implement core features",
+    goal_id=goal.id,
+    rationale="MVP needs basic functionality"
+)
+
+# 4. Create spec document from template
+spec_path = cog.doc_processor.create_from_template(
+    DocumentTemplate.TECHNICAL_SPEC,
+    "docs/mvp_spec.md"
+)
+
+# 5. Link document to task
+cog.intent_graph.link_artifact(task1.id, spec_path)
+
+# 6. Create collaboration session with agents
+session = cog.agent_coordinator.create_session(
+    goal="Build MVP",
+    coordinator_id="human-founder"
+)
+
+# 7. Process incoming documents (investor deck, market research)
+cog.process_new_file("~/Downloads/market_research.pdf")
+cog.process_new_file("~/Downloads/investor_deck.pptx")
+# These auto-organize into correct folders
+
+# 8. Get context when working on implementation
+context = cog.get_context(task_id=task2.id)
+print("Here's what you need to know:")
+for item in context.get_top_items(5):
+    print(f"  - [{item.type}] {item.title}")
+
+# 9. Make decisions and record them
+decision = cog.intent_graph.create_decision(
+    title="Use React for frontend",
+    rationale="Team knows it, large ecosystem, good performance",
+    alternatives_considered=["Vue.js", "Svelte", "Angular"]
+)
+cog.intent_graph.link_nodes(decision.id, task2.id, "related")
+
+# 10. Check overall progress
+cog.show_current_state()
+```
+
+## Integration with Existing Tools
+
+### Git Integration
+
+```python
+# When you make a commit
+commit_hash = "abc123"
+
+# Link it to task
+cog.intent_graph.link_artifact(
+    task_id="implement-auth",
+    artifact_path="src/auth.py",
+    commit_hash=commit_hash
+)
+
+# Now you can always find: why was this code written?
+tasks = cog.intent_graph.find_by_artifact("src/auth.py")
+for task in tasks:
+    print(f"This file exists because: {task.rationale}")
+```
+
+### IDE Integration
+
+```python
+# When you open a file in your IDE
+file_path = "src/auth.py"
+
+# Get full context
+context = cog.get_context(file_path=file_path)
+
+# Show in IDE sidebar:
+# - Why this file exists (linked tasks)
+# - What documentation exists
+# - Recent decisions about this code
+# - Related files
+```
+
+### Document Management
+
+```python
+# Watch downloads folder
+import time
+from watchdog.observers import Observer
+from watchdog.events import FileSystemEventHandler
+
+class DownloadHandler(FileSystemEventHandler):
+    def on_created(self, event):
+        if not event.is_directory:
+            print(f"New file detected: {event.src_path}")
+            cog.process_new_file(event.src_path)
+
+# Auto-process new downloads
+observer = Observer()
+observer.schedule(DownloadHandler(), "~/Downloads", recursive=False)
+observer.start()
+```
+
+## Best Practices
+
+### 1. Always Capture Intent
+
+```python
+# ❌ Bad - no context
+task = cog.create_task("Refactor auth module")
+
+# ✅ Good - clear intent
+task = cog.create_task(
+    "Refactor auth module to use dependency injection",
+    rationale="Current tight coupling makes testing difficult. DI will improve testability and modularity."
+)
+```
+
+### 2. Link Everything
+
+```python
+# Create task
+task = cog.create_task("Add user profile page")
+
+# Link the code
+cog.intent_graph.link_artifact(task.id, "src/components/UserProfile.tsx")
+
+# Link the docs
+cog.intent_graph.link_artifact(task.id, "docs/features/user_profile.md")
+
+# Link the design
+cog.intent_graph.link_artifact(task.id, "designs/user_profile.fig")
+
+# Now it's all connected!
+```
+
+### 3. Use Context Proactively
+
+```python
+# Before starting work, get context
+context = cog.get_context(task_id="current-task")
+
+# Check for blockers
+if context.filter_by_type("blocker"):
+    print("⚠ There are blockers - resolve these first")
+
+# Check for relevant decisions
+decisions = context.filter_by_type("decision")
+for decision in decisions:
+    print(f"Remember: {decision.title} - {decision.content}")
+```
+
+### 4. Let Documents Organize Themselves
+
+```python
+# ❌ Bad - manual organization
+# User manually moves file to "somewhere logical"
+
+# ✅ Good - semantic organization
+metadata = cog.semantic_fs.index_file(file_path)
+suggested = cog.semantic_fs.suggest_location(file_path)
+print(f"This belongs in: {suggested}")
+
+# Optional: auto-organize
+if input("Auto-organize? (y/n): ") == 'y':
+    cog.semantic_fs.auto_organize(file_path, dry_run=False)
+```
+
+### 5. Keep Docs in Sync
+
+```python
+# Regularly check doc status
+out_of_sync = cog.doc_manager.check_all_docs()
+
+if out_of_sync:
+    print(f"⚠ {len(out_of_sync)} documents need updating")
+    for doc in out_of_sync:
+        # Review and update
+        doc.update_from_code(next(iter(doc.code_references)))
+```
+
+## What Makes This Different?
+
+### Traditional Approach
+- Files in arbitrary folders
+- Context lives in people's heads
+- Docs get out of sync
+- Multi-agent chaos
+- Downloads folder anarchy
+
+### Cognitive OS Approach
+- Files organize by meaning and purpose
+- Context is captured and connected
+- Docs update themselves
+- Agents coordinate cleanly
+- Everything auto-organizes
+
+## The Big Picture
+
+The Cognitive OS solves the fundamental problem: **information silos and context loss**.
+
+Instead of:
+- Searching for files by name
+- Wondering why code exists
+- Docs that lie
+- Duplicate work
+- Lost decisions
+
+You get:
+- Files that know what they are
+- Code linked to purpose
+- Docs that update themselves
+- Clear collaboration
+- Preserved context
+
+This is how AI + humans should have been working all along.
