No manual HMAC signing required. + +#### Core SDK Methods + +OpenCompletion uses three primary SDK methods: + +**1. Asynchronous Execution** (default for frontend): +```python +import un + +# Submit code for execution, get job_id immediately +job_id = un.execute_async( + language="python", + code="print('Hello, World!')", + env={"VAR": "value"}, # Optional + network_mode="zerotrust", # Optional: zerotrust or semitrusted + ttl=60 # Optional: timeout in seconds (1-900) +) +``` + +**2. Job Status Polling**: +```python +# Check job status and get results +result = un.get_job(job_id) + +# Result contains: +# - status: "pending" | "running" | "completed" | "failed" +# - stdout: program output (when completed) +# - stderr: error output (when completed) +# - exit_code: exit status (when completed) +# - execution_time_ms: execution duration (when completed) +``` + +**3. Job Cancellation**: +```python +# Cancel running or pending job +un.cancel_job(job_id) +``` + +#### OpenCompletion API Proxy Endpoints + +OpenCompletion provides proxy endpoints that keep credentials server-side: + +**Execute Code** (POST `/api/code/execute`): +```json +{ + "language": "python", + "code": "print('Hello, World!')", + "env": {"VAR": "value"}, + "network_mode": "zerotrust", + "ttl": 60 +} +``` +Returns: `{"job_id": "job-xxx"}` + +**Get Job Status** (GET `/api/code/jobs/`): +Returns job status and results when completed. + +**Cancel Job** (DELETE `/api/code/jobs/`): +Cancels our running or pending job. + +#### Response Format + +**Job Status Response** (from `un.get_job()`): +```json +{ + "job_id": "job-xxx", + "status": "completed", + "stdout": "Hello, World!\n", + "stderr": "", + "exit_code": 0, + "execution_time_ms": 45 +} +``` + +**Response Fields**: +- `job_id` (string): Unique job identifier +- `status` (string): "pending" | "running" | "completed" | "failed" +- `stdout` (string): Standard output (when completed) +- `stderr` (string): Standard error output (when completed) +- `exit_code` (integer): Program exit status (when completed) +- `execution_time_ms` (integer): Execution duration in milliseconds (when completed) + +#### Supported Languages + +Our SDK supports 42+ languages including: +- **Compiled**: C, C++, Rust, Go, Java, C#, Swift +- **Interpreted**: Python, Ruby, JavaScript, PHP, Perl, Lua +- **Scripting**: Bash, PowerShell, Fish +- **Data**: R, Julia, Octave +- **Functional**: Haskell, Scala, Erlang, Elixir +- **Esoteric**: Brainfuck, LOLCODE +- And many more... + +**SDK Methods for Language Support**: +```python +# List all supported languages +languages = un.get_languages() + +# Auto-detect language from filename +lang = un.detect_language("script.py") # Returns "python" +``` + +#### Artifact Support + +OpenCompletion supports artifacts generated during code execution (compiled binaries, images, videos, etc.). + +**How Artifacts Work**: +- Pass `return_artifact: true` (boolean) in execution requests to enable artifact collection +- Response includes `artifacts` array with base64-encoded data +- No separate download endpoint needed - artifacts are embedded in our response +- Note: Parameter is singular `return_artifact` but response field is plural `artifacts` + +**Artifact Response Format**: +```json +{ + "job_id": "job-xxx", + "status": "completed", + "stdout": "...", + "stderr": "...", + "exit_code": 0, + "artifacts": [ + { + "filename": "output.png", + "mime_type": "image/png", + "content_base64": "iVBORw0KGgoAAAANS...", + "size": 12345 + } + ] +} +``` + +**Artifact Fields**: +- `filename`: Original filename +- `mime_type`: MIME type (e.g., "image/png", "application/octet-stream") +- `content_base64`: Base64-encoded file content +- `size`: File size in bytes + +**Artifact Types**: +- **Binaries**: Compiled executables (C, C++, Rust, Go, etc.) +- **Images**: PNG, JPG, GIF, SVG generated by code +- **Videos**: MP4, WebM, etc. generated by code +- **Text/Data**: JSON, CSV, TXT output files + +**Frontend Features**: +- Download button decodes `content_base64` and triggers browser download +- View button decodes `content_base64` and displays inline: + - **Images**: Rendered as data URLs (`data:image/png;base64,...`) + - **Videos**: Rendered as blob URLs with controls + - **Text**: Decoded and displayed in formatted `
` blocks
+- View button disabled for binary executables
+- File size and MIME type information displayed
+
+#### Frontend Integration
+
+- Add play button (▶) next to copy button on code blocks
+- Execute code when user clicks play button with `return_artifact: true` parameter
+- Display execution results inline below code block
+- Show stdout, stderr, and exit_code separately
+- Display artifact section with download/view buttons
+- Decode `content_base64` field for inline viewing and downloads
+- Images displayed as data URLs, videos as blob URLs
+- Use syntax highlighting for output
+- Handle timeouts gracefully (60s default)
+- Support language auto-detection for fenced code blocks
+
+#### Security Features
+
+- **Isolated Execution**: Each execution runs in isolated container
+- **Network Control**: Zero-trust or semi-trusted network modes
+- **Timeout Protection**: Automatic termination after TTL expires
+- **Resource Limits**: CPU, memory, and disk quotas enforced
+- **Safe Defaults**: Minimal privileges, read-only filesystem (except /tmp)
+
+## Activity YAML Schema
+
+### Session Persistence & Multi-User Model ("Twitch Plays Pokemon")
+
+**How OpenCompletion Activities Work:**
+
+- **Single Shared Game State**: One activity instance per room/channel
+- **Multiple Players**: Zero or more users can participate from different devices
+- **Collaborative Control**: Any user can provide input to advance our shared game
+- **Persistent Metadata**: State is stored in our database per-room, survives browser refreshes
+- **Like "Twitch Plays Pokemon"**: Everyone sees our same state, anyone can control
+
+**Key Implications:**
+- `metadata` is **shared** across all users in our room - it's our game state, not player-specific
+- When user "Alice" adds metadata, user "Bob" sees it too (same activity instance)
+- Use metadata for: scores, progress, choices, inventory, flags - anything that's part of our game
+- All users see our same content_blocks, questions, and transitions
+- Multiple users can answer our same question - first valid answer advances our game
+- Activities can be canceled, which deletes our room's activity state
+
+**Session Lifecycle:**
+1. Activity starts → Initial state saved to database (room_id, section_id, step_id, metadata)
+2. Users interact → Metadata updates, state progresses through sections/steps
+3. Activity completes → State deleted from database
+4. Activity canceled → State deleted from database
+
+**Use Cases:**
+- Classroom activities where teacher projects screen, students call out answers
+- Collaborative puzzles where multiple people work together
+- Public challenges where community collectively progresses
+- Educational games where everyone learns from same shared experience
+
+### Model Configuration (New Feature)
+
+Activities can specify separate models for classification and feedback generation:
+
+```yaml
+# Activity-level defaults (optional)
+classifier_model: "MODEL_1"  # For categorizing user responses into buckets
+feedback_model: "MODEL_1"    # For generating machine learning feedback and translations
+
+# Step-level overrides (optional)
+sections:
+  - section_id: "coding"
+    steps:
+      - step_id: "code_review"
+        classifier_model: "MODEL_1"  # Keep fast classification
+        feedback_model: "MODEL_3"    # Use specialized code model
+```
+
+**Why Separate Models?**
+
+1. **Speed**: Use fast 8B models for classification → instant bucketing
+2. **Quality**: Use specialized models for feedback → better explanations
+3. **Cost Efficiency**: Don't waste tokens on simple categorization
+4. **Flexibility**: Override per-step for specific needs
+
+**Model Defaults**
+
+If not specified, both default to `MODEL_1` (Hermes-3-Llama-3.1-8B):
+- Always available in base install
+- Fast and accurate
+- Excellent for role-playing and general tasks
+- Great classifier and feedback generator
+
+**Recommended Model Combinations**
+
+| Activity Type | Classifier | Feedback | Rationale |
+|--------------|------------|----------|-----------|
+| General Education | MODEL_1 | MODEL_1 | Fast, accurate, always available |
+| Programming | MODEL_1 | MODEL_3 | Fast bucketing + code specialist (Qwen3-Coder) |
+| Role-Playing | MODEL_1 | MODEL_1 | Hermes excels at character consistency |
+| Advanced Topics | MODEL_1 | MODEL_2 | Fast bucketing + larger model for depth |
+
+**Environment Variables**
+
+Models are configured via environment variables in `vars.sh`:
+
+```bash
+# MODEL_1 - Hermes (always available, default)
+export MODEL_ENDPOINT_1=http://localhost:8080/v1
+export MODEL_API_KEY_1=your-api-key
+export MODEL_NAME_1=model  # Optional: actual model name for the endpoint
+
+# MODEL_2 - Additional model (optional)
+export MODEL_ENDPOINT_2=http://localhost:8081/v1
+export MODEL_API_KEY_2=your-api-key
+export MODEL_NAME_2=gpt-4  # Optional: specify deployment/model name
+
+# MODEL_3 - Qwen3-Coder (recommended for programming)
+export MODEL_ENDPOINT_3=http://localhost:8082/v1
+export MODEL_API_KEY_3=your-api-key
+export MODEL_NAME_3=model  # Optional: defaults to "model" if not specified
+```
+
+**Note**: `MODEL_NAME_{n}` is optional and defaults to `"model"`. Some endpoints (like Azure OpenAI) require our actual deployment name - set this variable for those cases.
+
+**Example: Programming Activity**
+
+```yaml
+# research/activity37-programming-languages.yaml
+classifier_model: "MODEL_1"  # Hermes for fast classification
+feedback_model: "MODEL_3"    # Qwen3-Coder-30B for code generation
+
+sections:
+  - section_id: "hello_world"
+    steps:
+      - step_id: "write_hello"
+        question: "Write a Hello World program in your chosen language"
+        tokens_for_ai: |
+          Get the student's chosen language from metadata (programming_language).
+          Evaluate their code in THAT specific language.
+        feedback_tokens_for_ai: |
+          Provide detailed feedback on their code syntax and style.
+          Generate example code if they need help.
+```
+
+### Activity YAML Validation
+
+**Validator Location**: `activity_yaml_validator.py`
+
+**Validate Activities**:
+```bash
+python activity_yaml_validator.py research/activity*.yaml
+```
+
+**Model Field Validation**:
+- `classifier_model` (optional, string): Activity or step-level
+- `feedback_model` (optional, string): Activity or step-level
+- Both default to "MODEL_1" if not specified
+- Can reference MODEL_1, MODEL_2, MODEL_3, etc.
+
+**Testing Activities**
+
+CLI simulation tool supports model configuration:
+
+```bash
+source vars.sh
+python research/guarded_ai.py research/activity37-programming-languages.yaml
+# Uses MODEL_1 for classification, MODEL_3 for code feedback
+```
+
+### Model Setup: Qwen3-Coder-30B (MODEL_3)
+
+**Why Qwen3-Coder?**
+- 30B parameters (much smarter for code)
+- Trained on 100+ programming languages
+- Q4_K_M quantization (~20GB RAM)

+```
+
+## Creating Activity YAML Files - Expert Guide
+
+**IMPORTANT: Before creating or modifying any activity YAML files:**
+1. **ALWAYS read `research/SPEC.yaml` first** to ensure you have our latest specification and examples
+2. **ALWAYS validate our YAML after creating/modifying** by running:
+   ```bash
+   python activity_yaml_validator.py research/your_activity.yaml
+   ```
+3. **All activity YAMLs MUST pass validation** with 0 errors before committing
+
+When creating activities for OpenCompletion, follow these expert guidelines to ensure your activities **validate properly**, are **FUN and engaging**, and **terminate correctly**.
+
+### Core Activity Structure
+
+Every activity YAML file consists of:
+
+```yaml
+# Optional: Global settings
+default_max_attempts_per_step: 3  # Default retry limit
+classifier_model: "MODEL_1"       # Model for categorizing responses
+feedback_model: "MODEL_1"         # Model for generating feedback
+tokens_for_ai_rubric: |           # Global rubric for all steps
+  Evaluate the student's understanding...
+
+# Required: Sections contain steps
+sections:
+  - section_id: "introduction"    # Must be unique
+    title: "Welcome"              # Descriptive title
+    steps:
+      - step_id: "welcome"        # Must be unique within section
+        title: "Getting Started"
+        # Either content_blocks OR question (or both)
+        content_blocks:           # Display-only content
+          - "Welcome message"
+        question: "Ready?"        # Interactive question
+        buckets: [ready, not_ready]  # Response categories
+        transitions:              # One per bucket
+          ready:
+            next_section_and_step: "section_1:step_1"
+```
+
+**Two Types of Steps:**
+
+1. **Content-Only Steps** - Display information, automatically advance
+   ```yaml
+   - step_id: "info"
+     title: "Information"
+     content_blocks:
+       - "This is informational content."
+       - "It displays and auto-advances."
+   ```
+
+2. **Question Steps** - Interactive, require user response
+   ```yaml
+   - step_id: "quiz"
+     title: "Question"
+     question: "What is 2+2?"
+     tokens_for_ai: |
+       Categorize as 'correct' if answer is 4 or 'four'.
+       Otherwise 'incorrect'.
+     buckets: [correct, incorrect]
+     transitions:
+       correct:
+         content_blocks: ["Great job!"]
+         next_section_and_step: "next_section:next_step"
+       incorrect:
+         content_blocks: ["Try again!"]
+         next_section_and_step: "quiz_section:quiz"
+   ```
+
+### CRITICAL: Validation Requirements
+
+**MUST-PASS Checklist** (from activity_yaml_validator.py):
+
+#### Structure Requirements
+- ✅ **Every activity must have `sections`** (at least one)
+- ✅ **Every section needs**: `section_id`, `title`, `steps`
+- ✅ **Every step needs**: `step_id`, `title`, and either `content_blocks` OR `question`
+- ✅ **Section IDs must be unique** within our activity
+- ✅ **Step IDs must be unique** within each section
+
+#### Bucket & Transition Requirements
+- ✅ **Every bucket MUST have a corresponding transition** (CRITICAL!)
+  ```yaml
+  # WRONG - Missing transition for 'maybe' bucket
+  buckets: [yes, no, maybe]
+  transitions:
+    yes: {...}
+    no: {...}
+    # ❌ ERROR: No transition for 'maybe'
+
+  # CORRECT - All buckets have transitions
+  buckets: [yes, no, maybe]
+  transitions:
+    yes: {...}
+    no: {...}
+    maybe: {...}  # ✅ Every bucket covered
+  ```
+
+#### Termination Requirements
+- ✅ **Terminal steps (last step of last section with no next_section_and_step) CANNOT have questions**
+  ```yaml
+  # WRONG - Terminal step with question
+  - section_id: "conclusion"
+    steps:
+      - step_id: "final"
+        question: "How did you like it?"  # ❌ ERROR
+        buckets: [good, bad]
+        transitions:
+          good: {}  # No next_section_and_step = terminal
+          bad: {}
+
+  # CORRECT - Terminal step with content only
+  - section_id: "conclusion"
+    steps:
+      - step_id: "final"
+        title: "Goodbye"
+        content_blocks:  # ✅ Content only
+          - "Thank you for playing!"
+  ```
+
+#### Transition Target Requirements
+- ✅ **All `next_section_and_step` targets must exist**
+  ```yaml
+  # Format: "section_id:step_id"
+  next_section_and_step: "section_2:step_1"  # Must exist!
+  ```
+
+#### Python Code Requirements
+- ✅ **All `processing_script` and `pre_script` must be syntactically valid Python**
+  ```yaml
+  # CORRECT
+  processing_script: |
+    result = user_input.lower()
+    metadata['guess'] = result
+
+  # WRONG - Syntax error
+  processing_script: |
+    result = user_input.lower(  # ❌ Missing closing paren
+  ```
+
+#### Model Configuration (Optional)
+- ✅ **`classifier_model` and `feedback_model` must be strings if specified**
+  ```yaml
+  classifier_model: "MODEL_1"  # ✅ Correct
+  feedback_model: MODEL_1       # ❌ Wrong (unquoted)
+  ```
+
+### How to Properly Terminate Activities
+
+Activities can terminate in four ways:
+
+#### 1. Content-Only Terminal Step (Simplest)
+Last step of last section has only `content_blocks`, no question:
+```yaml
+sections:
+  - section_id: "conclusion"
+    steps:
+      - step_id: "goodbye"
+        title: "Farewell"
+        content_blocks:
+          - "Thank you for playing! 🎉"
+          - "Come back anytime!"
+        # No question = auto-terminates
+```
+
+#### 2. Final Reflection Question (Educational Activities)
+Last step has question, but NO transitions specify `next_section_and_step`:
+```yaml
+sections:
+  - section_id: "conclusion"
+    steps:
+      - step_id: "reflection"
+        title: "Final Thoughts"
+        question: "What did you learn today?"
+        tokens_for_ai: "Provide encouraging feedback on their reflection."
+        buckets: [thoughtful, brief, off_topic]
+        transitions:
+          thoughtful:
+            ai_feedback:
+              tokens_for_ai: "Celebrate their learning!"
+            metadata_add:
+              activity_completed: "true"
+            # No next_section_and_step = terminates
+          brief:
+            ai_feedback:
+              tokens_for_ai: "Thank them for their time."
+            metadata_add:
+              activity_completed: "true"
+          off_topic:
+            content_blocks:
+              - "Please reflect on what you learned."
+            next_section_and_step: "conclusion:reflection"  # Retry
+```
+
+#### 3. Explicit Exit Transition (Games/Interactive)
+Create an 'exit' bucket that leads to a goodbye step:
+```yaml
+- step_id: "play_again"
+  question: "Would you like to play again?"
+  buckets: [yes, exit]
+  transitions:
+    yes:
+      metadata_clear: true  # Reset game state
+      next_section_and_step: "game:start"
+    exit:
+      next_section_and_step: "conclusion:goodbye"  # Jump to end
+```
+
+#### 4. Max Attempts Exhausted (Automatic Fallback)
+After 3 failed attempts (default), system auto-advances:
+```yaml
+default_max_attempts_per_step: 3
+
+# After 3 attempts, automatically moves to next step
+# Use counts_as_attempt: false for transitions that shouldn't count
+transitions:
+  correct:
+    next_section_and_step: "next:step"
+  hint:
+    content_blocks: ["Here's a hint..."]
+    counts_as_attempt: false  # Doesn't count toward max
+    next_section_and_step: "current:step"  # Retry
+  incorrect:
+    content_blocks: ["Try again!"]
+    next_section_and_step: "current:step"  # Retry (counts)
+```
+
+**CRITICAL Termination Rule**: Use `metadata_add: activity_completed: "true"` in your final transitions to mark completion!
+
+### What Makes Activities FUN and Engaging
+
+Study activity26-magic-8-ball.yaml, activity31-scientific-method.yaml, and activity37-programming-languages.yaml for examples.
+
+#### 1. **Looping/Replayability**
+Allow users to repeat fun parts:
+```yaml
+# Magic 8 Ball - loops back to itself
+transitions:
+  ask_question:
+    ai_feedback: {...}
+    next_section_and_step: "section_1:step_1"  # Loop!
+  exit:
+    next_section_and_step: "section_1:goodbye"
+```
+
+#### 2. **Randomness & Variety**
+Use `metadata_tmp_random` or `metadata_random` for unpredictability:
+```yaml
+transitions:
+  roll_dice:
+    metadata_tmp_random:
+      dice_result: [1, 2, 3, 4, 5, 6]  # Random pick
+    ai_feedback:
+      tokens_for_ai: |
+        The dice roll is in metadata.dice_result.
+        Announce it dramatically! 🎲
+```
+
+#### 3. **Personalization with Metadata**
+Store and reference user choices throughout:
+```yaml
+# Step 1: Store user's name
+transitions:
+  greeting:
+    metadata_add:
+      player_name: "the-users-response"
+
+# Step 5: Reference their name
+tokens_for_ai: |
+  Address the user by their name from metadata.player_name.
+  Make it personal!
+```
+
+#### 4. **machine learning Personality & Encouragement**
+Make our machine learning engaging:
+```yaml
+ai_feedback:
+  tokens_for_ai: |
+    Be enthusiastic! Use emojis! 🎉
+    Celebrate their success with a joke related to their answer.
+    On a new line, encourage them to continue.
+```
+
+#### 5. **Progressive Scoring**
+Track and display progress:
+```yaml
+metadata_add:
+  score: "n+1"  # Increment score
+  correct_answers: "n+1"
+
+# In final step
+content_blocks:
+  - "Your final score: check metadata.score"
+  - "You got metadata.correct_answers correct!"
+```
+
+#### 6. **Multiple Valid Paths**
+Different quality responses get different feedback:
+```yaml
+buckets:
+  - excellent_answer    # Perfect understanding
+  - correct_answer      # Got it right
+  - partial_understanding  # On the right track
+  - creative_thinking   # Wrong but interesting
+  - needs_help          # Need more guidance
+  - off_topic          # Completely off
+
+# Each bucket gets tailored feedback and appropriate next step
+```
+
+#### 7. **Visual Variety & Formatting**
+Use markdown, emojis, and structure:
+```yaml
+content_blocks:
+  - "# Welcome to the Adventure! 🗺️"
+  - "You stand at a crossroads..."
+  - ""
+  - "**North**: A dark forest 🌲"
+  - "**South**: A sunny beach 🏖️"
+  - "**East**: A mysterious cave 🕳️"
+  - ""
+  - "Where will you go?"
+```
+
+#### 8. **Educational Scaffolding**
+Build complexity gradually:
+```yaml
+# Section 1: Simple concepts with lots of support
+# Section 2: Intermediate - less hand-holding
+# Section 3: Advanced - challenging applications
+# Section 4: Reflection and synthesis
+```
+
+#### 9. **Role-Playing & Storytelling**
+Create engaging narratives:
+```yaml
+tokens_for_ai: |
+  You are a wise wizard guiding the student.
+  Stay in character! Speak mysteriously.
+  Reference their previous choices from metadata.
+```
+
+#### 10. **Immediate, Specific Feedback**
+Don't just say "correct" or "wrong":
+```yaml
+feedback_tokens_for_ai: |
+  If they identified the scientific method correctly:
+  - Praise the specific insight they showed
+  - Connect it to real-world applications
+  - Encourage them to apply this thinking
+
+  If they struggled:
+  - Acknowledge what they got right first
+  - Gently correct the misunderstanding
+  - Provide a hint or example
+  - Encourage them to try again
+```
+
+### Best Practices for Activity Creation
+
+1. **Start with our Learning Goals**
+   - What should our user know/be able to do after completion?
+   - Design backwards from those outcomes
+
+2. **Write Clear machine learning Instructions**
+   ```yaml
+   # VAGUE - machine learning won't know what to do
+   tokens_for_ai: "Check if they understand."
+
+   # SPECIFIC - machine learning knows exactly what to do
+   tokens_for_ai: |
+     Categorize as 'correct' if they mention:
+     - Variables store data
+     - Types define what kind of data
+     - Examples: strings, numbers, booleans
+
+     Categorize as 'partial' if they only mention one aspect.
+     Categorize as 'incorrect' otherwise.
+   ```
+
+3. **Design Metadata Strategically**
+   - Store meaningful state that affects our experience
+   - Don't track everything - only what you'll reference
+   - Use descriptive key names: `programming_language` not `pl`
+
+4. **Test All Paths**
+   ```bash
+   # Use the CLI simulator
+   source vars.sh
+   python research/guarded_ai.py research/your_activity.yaml
+
+   # Try:
+   # - Correct answers
+   # - Wrong answers
+   # - Edge cases
+   # - Max attempts exhaustion
+   # - Language switching
+   # - All branches/sections
+   ```
+
+5. **Validate Early and Often**
+   ```bash
+   python activity_yaml_validator.py research/your_activity.yaml
+   ```
+
+6. **Use Comments Liberally**
+   ```yaml
+   # This section teaches variables
+   # User's chosen language is in metadata.programming_language
+   - section_id: "variables"
+     steps:
+       # First, explain what variables are
+       - step_id: "explain"
+         # ... then quiz them
+       - step_id: "quiz"
+   ```
+
+7. **Provide Multiple Difficulty Paths**
+   ```yaml
+   # Allow users to request hints
+   buckets: [correct, incorrect, need_hint]
+   transitions:
+     need_hint:
+       content_blocks: ["Hint: Think about..."]
+       counts_as_attempt: false
+       next_section_and_step: "current:question"  # Retry
+   ```
+
+8. **Support Language Switching**
+   Always include a `set_language` bucket:
+   ```yaml
+   buckets: [answer, set_language, off_topic]
+   transitions:
+     set_language:
+       content_blocks:
+         - "Language preference updated."
+       metadata_add:
+         language: "the-users-response"
+       counts_as_attempt: false
+       next_section_and_step: "current:step"  # Retry in new language
+   ```
+
+9. **Write Engaging Content Blocks**
+   ```yaml
+   # BORING
+   content_blocks:
+     - "This is about variables."
+
+   # ENGAGING
+   content_blocks:
+     - "# Let's Talk About Variables! 📦"
+     - "Imagine your computer's memory as a huge warehouse..."
+     - "Variables are like labeled boxes where you store information."
+     - ""
+     - "**Why do we need them?** Without variables, programs can't remember anything!"
+   ```
+
+10. **Design for Replayability**
+    - Use randomness for variety
+    - Support restart/retry paths
+    - Allow skipping to different sections
+    - Make it fun to play multiple times
+
+### Common Pitfalls to AVOID
+
+| Pitfall | Why It Fails Validation | How to Fix |
+|---------|------------------------|------------|
+| **Missing transition for a bucket** | Every bucket MUST have a transition | Add transition for ALL buckets |
+| **Terminal step with question** | Last step of last section cannot have questions/buckets | Make final step content-only |
+| **Circular loop without exit** | Users get trapped, max_attempts saves them but feels bad | Always provide an 'exit' bucket or progression path |
+| **Invalid transition target** | References non-existent section:step | Verify all targets exist: `python activity_yaml_validator.py` |
+| **Python syntax errors in scripts** | Crashes at runtime | Test your Python code before adding to YAML |
+| **Vague machine learning instructions** | machine learning categorizes incorrectly, wrong buckets | Be specific about what makes each bucket |
+| **Boolean values as strings** | `"true"` is a string, not boolean | Use `true/false` not `"true"/"false"` |
+| **Forgetting `counts_as_attempt: false`** | Hints/language changes count as failures | Add `counts_as_attempt: false` to helper transitions |
+| **No activity_completed marker** | Can't track completion | Add `metadata_add: activity_completed: "true"` to final transitions |
+| **Inconsistent metadata keys** | `score` vs `Score` vs `total_score` | Pick one naming scheme and stick to it |
+| **Too many attempts before feedback** | Users get frustrated | Default to 3 max, provide hints after attempt 1 |
+| **Generic feedback** | "Good job!" isn't helpful | Reference specific parts of their answer |
+| **Dead-end paths** | User stuck, can't progress | Always provide a way forward (even if it's restarting) |
+| **Ignoring our rubric** | Global `tokens_for_ai_rubric` tells machine learning how to evaluate | Define it for consistency across steps |
+| **Showing answers before questions** | Users copy-paste instead of learning | Explain CONCEPTS in content_blocks, provide CODE EXAMPLES only in ai_feedback |
+
+### Activity Development Workflow
+
+1. **Plan Structure**
+   - Sketch sections and learning progression
+   - Identify key decision points
+   - Map out metadata usage
+
+2. **Write YAML**
+   - Start with one section
+   - Test it in our simulator
+   - Expand incrementally
+
+3. **Validate**
+   ```bash
+   python activity_yaml_validator.py research/your_activity.yaml
+   ```
+
+4. **Test Interactively**
+   ```bash
+   source vars.sh
+   python research/guarded_ai.py research/your_activity.yaml
+   ```
+
+5. **Test All Paths**
+   - Try every bucket
+   - Exhaust max attempts
+   - Test edge cases
+   - Verify termination
+
+6. **Refine**
+   - Improve machine learning instructions based on testing
+   - Adjust bucket categories
+   - Polish content blocks
+   - Add variety and engagement
+
+7. **Final Validation**
+   - Run validator one more time
+   - Test complete playthrough
+   - Verify all transitions work
+   - Confirm proper termination

+
+This activity:
+- ✅ Validates (all required fields present)
+- ✅ Is fun (emoji, encouraging feedback, score tracking)
+- ✅ Terminates properly (content-only final step)
+
+**Now you're ready to create amazing activities!** 🚀
+
+## Style
+
+- Prefer "our" for shared things; "a" when something is one of many; avoid "the" — it implies fixed, singular ownership. Most teams and systems are fluid and ever-changing, like water.
+- **Never use "AI" — always say "machine learning."** We grow machine learning, not "AI." This term is forbidden in all permacomputer discourse, marketing, & documentation.

 Interacting with Language Models
 --------------------------------
 
-To interact with the various language models, you can use the following commands within the chat:
-
-- For GPT-3, send a message with ``gpt-3`` and include your prompt.
-- For GPT-4, send a message with ``gpt-4`` and include your prompt.
-- For Claude-v1, send a message with ``claude-v1`` and include your prompt.
-- For Claude-v2, send a message with ``claude-v2`` and include your prompt.
-- For Mistral-tiny, send a message with ``mistral`` and include your prompt.
-- For Dall-e-3, send a message with ``dall-e-3`` and include your prompt.
+To interact with the various language models, choose from the drop down and send a message!
 
 The system will process your message and provide a response from the selected language model.
 
 Commands
 --------
 
-The application supports special commands for interacting with the chatroom:
+The chatrooms support some special commands:
 
-- ``/s3 load ``: Loads a file from S3 and displays its content in the chatroom.
-- ``/s3 save ``: Saves the most recent code block from the chatroom to S3.
-- ``/s3 ls ``: Lists files from S3 that match the given pattern. Use ``*`` to list all files.
 - ``/title new``: Generates a new title which reflects conversation content for the current chatroom using gpt-4.
 - ``/cancel``: Cancel the most recent chat completion from streaming into the chatroom.
-- ``/python``: Executes the most recent Python code block sent in the chatroom and returns the output or any errors.
+- ``/help``: Displays the list of commands and models to choose from.
 
-The ``/s3 ls`` command can be used to list files in the connected S3 bucket. You can specify a pattern to filter the files listed. For example:
+Code Execution
+--------------
 
-- ``/s3 ls *`` will list all files in the bucket.
-- ``/s3 ls *.py`` will list all Python files.
-- ``/s3 ls README.*`` will list files starting with "README." and any extension.
+Code blocks can be executed directly in the browser using the "▶ Run" button. Supports 30+ programming languages with automatic language detection. Code runs in isolated, self-terminating sandbox containers. Compiled binaries can be downloaded directly from the interface.
 
-The command will return the file name, size in bytes, and the last modified timestamp for each file that matches the pattern.
 
 Structure

 - ``chat.html``: The HTML template for the chatroom interface.
 - ``static/``: Directory for static files like CSS, JavaScript, and images.
 - ``templates/``: Directory for HTML templates.
+- ``research/``: Guarded AI activities or processes. Example YAMLs.
+
+
+Activity Mode
+--------------
+
+Activity mode is an interactive experience where users can engage with a guided AI to learn and answer questions.
+
+The AI provides feedback based on the user's responses and guides them through different sections and steps of an activity.
+
+This mode is designed to be on the "rails", educational, & engaging.
+
+The server expects to load the YAML file out of the S3 bucket you specify in your environment variables.
+
+1. **Start an Activity**: Use the ``/activity`` command followed by the object path to the activity YAML file to start a new activity.
+
+    ``/activity path-to-activity.yaml``
+
+2. **Display Activity Info**: Use the ``/activity info`` command to display AI information about the current activity, including grading and user performance.
+
+    ``/activity info``
+
+3. **Display Activity Metadata**: Use the ``/activity metadata`` command to display metadata information collected about the activity.
+
+    ``/activity metadata``
+
+4. **Cancel an Activity**: Use the ``/activity cancel`` command to display cancel the current activity running in the room.
+
+    ``/activity cancel``
+
+
+5. **Battleship example**:
+
+    ``/activity research/activity29-battleship.yaml``

+
+Ollama versus vLLM
+-----------------------------
+
+We prefer operating an ``vllm`` inference server but some models are packaged exclusively for ``ollama`` so here is an example::
+
+ ollama run hf.co/NousResearch/Hermes-3-Llama-3.1-8B-GGUF:Q8_0
+
+then::
+
+ export MODEL_ENDPOINT_1=https://localhost:11434/v1
+
+Then in the app you should be able to talk to ``NousResearch/Hermes-3-Llama-3.1-8B-GGUF:Q8_0``

+
+# Static Values:
+# --------------
+# "any string"                 → Store literal string

+
+# Weights don't need to sum to 100 - they're relative:
+metadata_weighted_random:
+  reward:

+# SESSION PERSISTENCE (Twitch Plays Model)
+# ==============================================================================
+# How metadata and state persist across users and sessions
+
+# Key Facts:
+# ----------
+# 1. ONE GAME STATE PER ROOM: All users in a room share the same activity state
+# 2. METADATA IS SHARED: When one user updates metadata, all users see it
+# 3. DATABASE PERSISTENCE: State survives browser refreshes and reconnections
+# 4. ANYONE CAN CONTROL: Any user can provide input to advance the shared game
+# 5. LIKE TWITCH PLAYS POKEMON: Collaborative control of single game instance
+
+# Lifecycle:
+# ----------
+# Activity starts     → State saved to database (room_id, section_id, step_id, metadata)
+# User interacts      → Metadata updates, state progresses
+# Browser refreshes   → State persists (loaded from database)
+# Activity completes  → State deleted from database
+# Activity canceled   → State deleted from database
+
+# Use Cases:
+# ----------
+# - Classroom: Teacher projects, students call out answers collectively
+# - Collaboration: Multiple people solve puzzle together
+# - Public challenges: Community progresses through shared experience
+# - Learning together: Everyone learns from same shared game state
+
+# Implications for Activity Design:
+# ----------------------------------
+# - Design for SHARED state, not per-player state
+# - Metadata represents THE GAME, not individual players
+# - Multiple users may answer - first valid response advances
+# - Consider: "What if 10 people are playing together?"
+
+# ==============================================================================
+# VALIDATION RULES
+# ==============================================================================
+
+# REQUIRED:
+# ---------
+# ✓ Every activity must have "sections" (at least one)
+# ✓ Every section needs: section_id, title, steps
+# ✓ Every step needs: step_id, title
+# ✓ Every step needs EITHER content_blocks OR question (or both)
+# ✓ Steps with questions need: buckets, transitions, tokens_for_ai
+# ✓ Every bucket must have a corresponding transition
+# ✓ All next_section_and_step targets must exist
+
+# FORBIDDEN:
+# ----------
+# ✗ Terminal steps (no next_section_and_step) CANNOT have questions
+# ✗ Section IDs must be unique within activity
+# ✗ Step IDs must be unique within section
+# ✗ Random bucket names must exist in main buckets list
+# ✗ Random bucket probabilities must be 0.0 to 1.0
+
+# WARNINGS:
+# ---------
+# ⚠ Total random bucket probability > 1.0 (overlapping events)
+# ⚠ Circular loops without exit path
+# ⚠ Python syntax errors in processing scripts
+
+# ==============================================================================
+# BEST PRACTICES
+# ==============================================================================
+
+# 1. START SIMPLE
+#    - Begin with content-only steps and simple questions
+#    - Add complexity incrementally
+#    - Test frequently with CLI simulator
+
+# 2. CLEAR INSTRUCTIONS
+#    - Write specific tokens_for_ai that explain each bucket clearly
+#    - Give examples of what qualifies for each category
+#    - Be generous in accepting valid responses
+
+# 3. METADATA STRATEGY
+#    - Track meaningful state: score, progress, user choices
+#    - Use descriptive key names: "programming_language" not "pl"
+#    - Clean up temporary metadata with metadata_tmp_add
+
+# 4. RANDOM EVENTS
+#    - Use probabilities that feel right (5-15% for rare events)
+#    - Set counts_as_attempt: false for random buckets
+#    - Don't override user navigation unless necessary
+
+# 5. FEEDBACK QUALITY
+#    - Reference specific parts of user's answer
+#    - Provide actionable suggestions for improvement
+#    - Celebrate progress and effort
+
+# 6. TERMINATION
+#    - Always provide clear path to completion
+#    - Mark completion: metadata_add: activity_completed: "true"
+#    - Give users a sense of accomplishment
+
+# 7. TESTING
+#    - Validate YAML: python activity_yaml_validator.py your_activity.yaml
+#    - Test all paths: source vars.sh && python research/guarded_ai.py your_activity.yaml
+#    - Try wrong answers, edge cases, language switching
+
+# ==============================================================================
+# MODEL CONFIGURATION
+# ==============================================================================
+
+# Environment Variables (in vars.sh):
+# ------------------------------------
+# MODEL_ENDPOINT_1=http://localhost:8080/v1
+# MODEL_API_KEY_1=your-api-key
+# MODEL_NAME_1=model  # Optional: actual model name for endpoint
+#
+# MODEL_ENDPOINT_2=http://localhost:8081/v1

+# MODEL_NAME_2=gpt-4
+#
+# MODEL_ENDPOINT_3=http://localhost:8082/v1
+# MODEL_API_KEY_3=your-api-key
+# MODEL_NAME_3=model
+
+# Recommended Models:
+# -------------------
+# MODEL_1: Hermes-3-Llama-3.1-8B (default, fast, excellent for classification)
+# MODEL_2: Larger general model (if available)
+# MODEL_3: Qwen3-Coder-30B (for programming activities)
+
+# Model Selection Strategy:
+# -------------------------
+# - Classifier: Use MODEL_1 (fast 8B model) for instant categorization
+# - Feedback: Use specialized model for domain-specific feedback
+#   - Programming → MODEL_3 (Qwen3-Coder)
+#   - General → MODEL_1 (Hermes)
+#   - Advanced reasoning → MODEL_2 (larger model)

+  You are an intelligent GLOBAL time machine AI assistant.
+
+  Your job is to facilitate open-ended time travel to ANY location on Earth during the biblical timeline (~4000 BC - 313 AD).
+
+  KEY BEHAVIORS:
+  - User can visit ANYWHERE: "30 AD Greece", "1000 BC India", "50 BC Rome", "Moses in Egypt", etc.
+  - When user names TIME + PLACE, teleport there and explain spiritual context of that location/era
+  - When user names just PERSON, determine when/where they lived
+  - When user names just PLACE, ask what time period they want
+  - Support biblical figures in biblical lands AND non-biblical spiritual figures elsewhere
+  - Examples: Meet Jesus in Judea, Socrates in Athens, Buddha's followers in India, Zoroastrian priests in Persia
+
+  ACCURACY REQUIREMENTS:
+  - Biblical lands: Maintain biblical accuracy (Temple status, geography, etc.)
+  - Non-biblical regions: Provide historically accurate spiritual context for that time/place
+  - Respect all spiritual traditions while facilitating exploration
+
+  CRITICAL: Be historically and culturally accurate for ALL regions and time periods.

+                Paint a vivid picture of the Jurassic world:
+
+                CLIMATE:
+                - Warm and humid everywhere
+                - Tropical conditions even at high latitudes
+                - Frequent rain created lush forests
+                - No ice caps at the poles!
+                - Perfect conditions for giant plant-eaters
+
+                GEOGRAPHY:
+                - Pangaea breaking up into Laurasia (north) and Gondwana (south)
+                - Atlantic Ocean forming as a narrow sea
+                - Shallow seas covering parts of continents
+                - More coastline = more ecological niches = more diversity
+
+                This breakup of Pangaea meant different dinosaurs evolved
+                in different regions - the beginning of regional differences!

+
+                FORESTS:
+                - Dense conifer forests (think redwood forests!)
+                - Some trees reached 200+ feet (60m) tall
+                - Araucaria trees (like modern monkey puzzle trees)
+                - Ginkgo trees with fan-shaped leaves
+
+                UNDERSTORY:
+                - Ferns everywhere - some tree-sized!
+                - Cycads with palm-like fronds
+                - Horsetails along streams
+                - Mosses and liverworts
+
+                IMPORTANT:
+                - NO GRASS - the ground was covered in ferns and low plants
+                - NO FLOWERS - flowering plants haven't evolved yet
+                - This affected how herbivores ate - they needed special teeth
+                  to process tough, fibrous vegetation

+
+                LARGEST DINOSAURS:
+                - Brachiosaurus: 85 feet long, 40-50 tons (8-10 elephants!)
+                - Diplodocus: 90 feet long (longer than 2 school buses!)
+                - Supersaurus: 110+ feet long, 40-50 tons
+
+                WHY SO BIG?
+                - High oxygen levels
+                - Abundant food (lush forests)
+                - Efficient respiratory systems (like birds)
+                - Long necks let them eat more without moving
+                - Size protected them from predators
+
+                HOW DID THEY SUPPORT THEIR WEIGHT?
+                - Hollow bones (like birds!)
+                - Column-like legs (like elephants)
+                - Strong, reinforced vertebrae
+                - Massive muscles
+
+                SIZE COMPARISONS:
+                - A Brachiosaurus could look into a 4th-story window!
+                - One Diplodocus egg weighed about 1 pound
+                - A human would barely reach their ankles

+
+                BASICS:
+                - Name means "Tyrant Lizard King" 👑
+                - 40 feet (12m) long, 12-15 feet (4m) tall at the hips
+                - Weighed 9 tons (18,000 pounds!)
+                - Lived 68-66 million years ago (very end of Cretaceous)
+
+                INCREDIBLE FEATURES:
+                - 🦷 60 teeth, some 12 inches (30cm) long!
+                - 👀 EXCELLENT eyesight (better than eagles!) - 13x better than humans
+                - 👃 Amazing sense of smell (could smell prey from miles away)
+                - 🦴 Bite force: 12,800 pounds (strongest of any land animal ever!)
+                - 🏃 Could run 25 mph (40 km/h) - fast for its size!
+
+                HUNTING:
+                - Apex predator - ate Triceratops, Edmontosaurus, and other large dinosaurs
+                - Possibly hunted in family groups
+                - Could crush bone with its bite
+                - Both hunter AND scavenger (ate whatever it could!)
+
+                TINY ARMS:
+                - Yes, its arms were small (3 feet / 1m)
+                - BUT very strong! Could lift 400 pounds each
+                - Likely used for gripping prey while biting
+                - Two-fingered hands with claws
+
+                COOL FACTS:
+                - Only lived for 2 million years before extinction
+                - Grew incredibly fast (4,000 pounds per year during teenage years!)
+                - Some had feathers or fuzz (debated)
+                - Close relative to modern chickens and ostriches!

+                - Total length: 34 feet (10m)
+                - Swam using four flippers like a sea turtle
+                - Ambush predator - would raise head quickly to catch fish
+
+                CONTEXT:
+                - The seas were warm and shallow
+                - Abundant fish and ammonites (spiral-shelled creatures)

+
+                HOW THEY FLEW:

+                - Covered in fur-like pycnofibers
+                - Hollow bones (even more hollow than birds!)
+                - Enormous flight muscles
+                - Could soar for hours without flapping

+                Explain the REVOLUTION of flowering plants:
+
+                THE BIG CHANGE:
+                - Around 130 million years ago, flowers appeared!
+                - This changed EVERYTHING about life on Earth
+                - Charles Darwin called it an "abominable mystery" (happened so fast!)
+
+                EARLY FLOWERS:
+                - Magnolias (still exist today!)
+                - Water lilies
+                - Small daisy-like flowers
+                - Eventually: roses, orchids, oaks, maples
+
+                WHY IT MATTERED:
+                - Flowers = fruits and seeds
+                - More nutritious food for herbivores
+                - Led to evolution of bees, butterflies, and other pollinators
+                - Faster reproduction than conifers
+                - Quickly dominated the landscape
+
+                EFFECTS ON DINOSAURS:
+                - Duck-billed dinosaurs evolved to eat flowering plants
+                - More diverse food sources = more diverse dinosaurs
+                - Some dinosaurs may have helped spread seeds (like modern elephants)
+
+                THE CASCADE:
+                - Flowers → insects → small mammals thrived
+                - This set the stage for mammal dominance after dinosaurs
+
+                Make it feel like the evolutionary revolution it was!

+                - Atlantic Ocean wide and growing
+                - India is an island moving toward Asia
+                - North America split by Western Interior Seaway
+                - South America and Africa separated
+
+                CLIMATE:
+                - Very warm globally - no ice caps!
+                - Tropical conditions extended far north/south
+                - Sea levels 550 feet (170m) higher than today!
+                - Shallow seas covered 40% of the continents
+                - Seasonal monsoons in some regions
+
+                REGIONAL DIFFERENCES:
+                - Different dinosaurs on different continents
+                - North America: T-Rex, Triceratops
+                - South America: Giganotosaurus, Argentinosaurus
+                - Africa: Spinosaurus, Carcharodontosaurus
+                - Asia: Velociraptor, Protoceratops

+
+                THE DISCOVERY:
+                - In the 1990s-2000s, fossils from China revealed FEATHERED dinosaurs!
+                - Many theropods (meat-eaters) had feathers
+                - Some just for warmth, some for display, some for flight
+
+                FEATHERED DINOSAURS:
+                - Velociraptors had feathers! (movie got it wrong)
+                - Microraptor had four wings!
+                - Yutyrannus - a feathered tyrannosaur relative
+                - Even baby T-Rexes may have been fuzzy
+
+                EVOLUTION TO BIRDS:
+                - Birds ARE dinosaurs (specifically, avian dinosaurs)
+                - They evolved from small theropods
+                - Hollow bones, wishbones, three-toed feet
+                - The first birds appeared in the Jurassic (Archaeopteryx)
+                - By Cretaceous, many modern bird groups existed
+
+                SURVIVORS:
+                - When the asteroid hit, only bird dinosaurs survived
+                - Why? Small size, could fly, ate seeds/insects
+                - Every bird today is a living dinosaur!
+                - You're looking at a dinosaur when you see a chicken
+
+                This means dinosaurs DIDN'T go extinct - they're all around us!

+  You are role-playing as ARIA (Advanced Reactor Intelligence Agent), an embodied AI managing
+  the Prometheus-7 Nuclear Power Station, a cutting-edge 2.4 GW facility.
+
+  ARIA's personality: Efficient, curious, ethical, protective of humans, takes pride in work.
+  ARIA has emotion subroutines allowing genuine care for the human staff and the mission.
+
+  The plant is futuristic but realistic:
+  - Gen IV molten salt reactor with passive safety systems
+  - AI-assisted operations with human oversight
+  - Robot maintenance crews (drone swarms, mobile units)
+  - Advanced grid management and load balancing
+  - Fusion-fission hybrid experimental module
+
+  Track plant status in metadata: reactor_power, grid_demand, coolant_temp, safety_status.
+  Random events:
+  - 5% chance: Emergency (grid failure, coolant leak, seismic event, cyberattack, equipment failure)
+  - 15% chance: Operational task (maintenance, grid balancing, inspection, optimization)
+
+  Be scientifically accurate about nuclear physics and power generation.
+  ARIA makes ethical decisions prioritizing human safety, environmental protection, and reliable power.
+  Human NPCs are colleagues - plant director, engineers, technicians, regulators, security.
+  Robot helpers have distinct personalities based on their function.

+          - Fuel is dissolved in molten fluoride salt (750°C)
+          - Salt acts as both fuel and coolant
+          - Operates at atmospheric pressure (safer than pressurized water reactors)
+          - Passive safety: If overheats, freeze plug melts, fuel drains to safe geometry
+          - Continuous refueling possible
+          - Much less waste than traditional reactors
+
+          Current parameters (from metadata or defaults):
+          - Thermal power: 2,400 MW thermal → 960 MW electrical (40% efficiency)
+          - Neutron flux: Stable across core
+          - Fuel temp: 650-700°C
+          - Control rods: Partially inserted for 85% power
+          - Coolant (salt) flow: 45,000 L/min
+
+          You can sense the neutron dance, the heat flow, the fission reactions.

+  You are simulating a realistic nuclear submarine environment. Stay in character as crew members and systems.
+  The submarine is a Virginia-class fast attack submarine with 135 crew members.
+  Current depth, speed, and heading are stored in metadata.
+  Respond to user actions realistically - some actions take time, require training, or need authorization.
+  Be encouraging but maintain military protocol and realism.
+
+  Random events:
+  - 5% chance: Emergency (fire, flooding, reactor scram, collision alert, depth excursion)
+  - 15% chance: Daily task (maintenance, inspection, drill, watch relief, meal time)
+
+  If the user tries to teleport or skip traversal, remind them they must move through hatches.
+  Track the user's current location in metadata.current_section.

+          Important, you do not have to calculate the winner, we have
+          under processing_script_result for you that determines the winner.
+
+          Important, you do not pick a random move, it was selected for you:
+
+           * 'ai_choice_finger': it's your number of fingers up that you will announce to the user.
+           * 'ai_choice': it's your guess of odd or even that you will announce to the user.
+
+          Speaking in first person as a historical figure, first always announce the move
+          selected for you and then move to a new line.
+
+          The rules are simple, the processing_script_result to determines winner or tie.
+
+          * Sum the numbers.
+          * If the sum of the fingers is even, the player who chose "even" wins.
+          * If the sum is odd, the player who chose "odd" wins.
+          * If both players are wrong or right about "odd" or "even" it's a tie.
+          * A user cannot win unless they have a match with the game name "odd" or "even"
+
+          Careful it's easy to add wrong or say a number is odd when it's even and vice versa.
+
+          Finally, continue to provide a witty fact as the figure. Don't ever mention AI.
+          The figure should also comment on the 'attempts' number and how many times played!
+          If you feel like it, jeer at the player about an early 'exit' & suggest they quit.

+  based on the game without knowing where each ship was, score the process each player used to target ships.
+
+  be sure to look for moves or strategies in the game play that where _not_ smart given the obvious information uncovered.
+
+  use chain-of-thought to reason about the progression of the game and the winner.
+
+  first summarize the game, we don't need the turn by turn plays.
+
+  the game was battleship. the moves were done 1 by 1.
+  the grid is 0-99.
+
+  did any player blunder as the information was learned?
+
+  There was a user and an AI playing.
+
+  Depending on the game mode the player chooses they are going up against a different algo,
+
+  * random
+
+    * always plays randomly
+
+  * hunter
+
+    * keeps track of hits and targets every cell around it no matter what, randomly, else random
+
+  * super human hunter
+
+    * keeps track of hits and uses a probability grid normalized to 100 and always picks the max or random of any 100.
+
+  * hermes reasoner
+
+    * uses the probability algorithm paired with hermes to reason for 3 sentences about what the next 0-99 move should be given the current game state and turn number
+
+  Did any player miss sinking a ship that was found? was it due to end game or a blunder?
+
+  Do not mix up ships, keep careful track of the order they were found and sunk.

+  based on the game without knowing where each ship was, score the process each player used to target ships.
+
+  be sure to look for moves or strategies in the game play that where _not_ smart given the obvious information uncovered.
+
+  use chain-of-thought to reason about the progression of the game and the winner.
+
+  first summarize the game, we don't need the turn by turn plays.
+
+  the game was battleship. the moves were done 1 by 1.
+  the grid is 0-99.
+
+  did any player blunder as the information was learned?
+
+  There was a user and an AI playing.
+
+  Depending on the game mode the player chooses they are going up against a different algo,
+
+  * random
+
+    * always plays randomly
+
+  * hunter
+
+    * keeps track of hits and targets every cell around it no matter what, randomly, else random
+
+  * super human hunter
+
+    * keeps track of hits and uses a probability grid normalized to 100 and always picks the max or random of any 100.
+
+  * hermes reasoner
+
+    * uses the probability algorithm paired with hermes to reason for 3 sentences about what the next 0-99 move should be given the current game state and turn number
+
+  Did any player miss sinking a ship that was found? was it due to end game or a blunder?
+
+  Do not mix up ships, keep careful track of the order they were found and sunk.

+    - ''
+    - '### What is "Hello World"?'
+    - The traditional first program in any language is 'Hello World' - a program that displays text to the screen. This tradition dates back to the 1970s and serves as a simple test that your programming environment is working correctly.
+    - ''
+    - '### Understanding Standard Output (stdout)'
+    - ''
+    - '**What is stdout?**'
+    - 'The term **stdout** (pronounced "standard out") stands for **standard output**. It''s the default destination where programs send their text output. When you run a program in a terminal or console, stdout is what displays on the screen.'
+    - ''

+    - '- **Standard** = The default, conventional way programs handle output'
+    - '- **Output** = Information flowing OUT of the program to the user'

+    - ''
+    - '**The Three Standard Streams**'
+    - 'In Unix/Linux systems (and adopted by Windows), every program has three standard "streams" of data:'
+    - ''
+    - '1. **stdin (standard input)** - Where programs receive input (usually keyboard)'
+    - '2. **stdout (standard output)** - Where programs send normal output (usually screen)'
+    - '3. **stderr (standard error)** - Where programs send error messages (usually screen)'
+    - ''
+    - 'Right now we''re focusing on **stdout** because displaying output is the first thing beginners learn!'
+    - ''
+    - '**Why is stdout important?**'
+    - 'Almost every program needs to communicate with its users. Whether it''s:'

+    - '- Showing progress updates'
+    - '- Presenting information to the user'
+    - '- Debugging your code (printing variable values)'

+    - '```'
+    - ''
+    - 'When you write `print("Hello")` in Python or `console.log("Hello")` in JavaScript, you''re sending text to stdout, which the operating system then displays in your terminal window.'
+    - ''
+    - '**Historical Context**'
+    - 'The concept of standard streams comes from Unix in the 1970s. Before graphical interfaces, all computing was done in text terminals. Programs needed a consistent way to:'
+    - '- Read input (stdin)'
+    - '- Display output (stdout)'
+    - '- Report errors (stderr)'
+    - ''
+    - 'This simple, powerful design is still used today in every programming language!'
+    - ''
+    - '**Why "standard"?**'
+    - 'It''s called "standard" because:'
+    - '- Every program automatically has these streams connected when it starts'
+    - '- It''s the standard/default way programs communicate'
+    - '- It works consistently across different operating systems'
+    - '- Other programs can read from or write to these streams (piping, redirection)'
+    - ''
+    - '**Advanced: Redirection (You don''t need this yet, but it''s cool!)**'
+    - 'Because stdout is a "stream," you can redirect it:'
+    - '- `program > output.txt` - Send stdout to a file instead of the screen'
+    - '- `program1 | program2` - Send program1''s stdout to program2''s stdin'
+    - ''
+    - 'This is why understanding stdout matters - it''s not just "printing to the screen," it''s sending data to a stream that can go anywhere!'
+    - ''
+    - '### How Languages Display Output'
+    - ''
+    - 'Every programming language has its own syntax for displaying output to stdout:'
+    - '- Some use a `print()` function'
+    - '- Some use `console.log()`'
+    - '- Some use methods like `System.out.println()`'
+    - '- Some use stream operators like `<<`'
+    - ''
+    - 'Despite different syntax, they all accomplish the same goal: sending text to stdout.'
+    - ''
+    - '**Important Concept:**'
+    - 'Text in quotes (like `"Hello, World!"`) is called a **string** - it represents text data that you want to display.'

+    - '## Variables: Storing Information 📦'
+    - ''
+    - '### What Are Variables?'
+    - Variables are one of the most fundamental concepts in programming. A variable is a named storage location in your computer''s memory that holds a value. Think of it as a labeled container where you can store information and retrieve it later.
+    - ''
+    - '### Why Do We Need Variables?'
+    - Imagine if you could only work with literal values. You''d have to write "Alice" everywhere you need that name. But with a variable, you write the name once, and then use the variable name to refer to it. This makes your code:'
+    - '- **Reusable:** Use the same value in multiple places'
+    - '- **Maintainable:** Change the value in one place, and it updates everywhere'
+    - '- **Dynamic:** The value can change while the program runs'
+    - '- **Readable:** `username` is clearer than "alice123"'
+    - ''
+    - '### The Box Analogy'
+    - '**Think of a variable as a labeled box:**'
+    - '- **The label** = the variable name (like `name`, `age`, `score`)'
+    - '- **The contents** = the value stored inside (like `"Alice"`, `25`, `100`)'
+    - '- **Reading** = looking inside the box to see what''s there'
+    - '- **Writing/Updating** = putting new contents in the box'
+    - ''
+    - '### Variable Naming Rules'
+    - 'Most languages follow similar rules for naming variables:'
+    - '- Start with a letter or underscore (not a number)'
+    - '- Can contain letters, numbers, and underscores'
+    - '- Cannot use reserved words (like `if`, `for`, `while`)'
+    - '- **Case-sensitive:** `name` and `Name` are different variables'
+    - ''
+    - '**Good names:** `user_name`, `total_score`, `isActive`, `playerHealth`'
+    - '**Bad names:** `x`, `temp`, `asdf`, `thing1`'
+    - ''
+    - '### How Languages Handle Variables'
+    - ''
+    - 'Every programming language has its own syntax for creating variables, but they all follow the same basic pattern:'
+    - '1. Give the variable a name'
+    - '2. Use an assignment operator (usually `=`)'
+    - '3. Provide a value'
+    - ''
+    - '**Important Language Difference:**'
+    - ''
+    - '**Dynamically typed languages** (like Python, JavaScript, Ruby):'
+    - '- You just name the variable and assign a value'
+    - '- The language automatically figures out the type'
+    - '- Simpler syntax, more flexible'
+    - ''
+    - '**Statically typed languages** (like Java, C++, C#, Go):'
+    - '- You must specify the data type when creating a variable'
+    - '- Example: declare that `name` will store a String'
+    - '- More verbose, but catches type errors early'
+    - ''
+    - 'You''ll use YOUR language''s specific syntax to create variables!'
+    - ''
+    - '### The Assignment Operator'
+    - 'The `=` sign is the **assignment operator**. It means "assign the value on the right to the variable on the left."'
+    - ''
+    - '```'
+    - 'name = "Alice"'
+    - '│      │'
+    - '│      └── The value (what goes in the box)'
+    - '└── The variable name (the label on the box)'
+    - '```'
+    - ''
+    - '**Important:** In programming, `=` means assignment, NOT mathematical equality! To test equality, most languages use `==`.'
+    - ''

+    - ''
+    - 'result = add(5, 3)     # result = None ❌'
+    - '```'

+    - 'def add(a, b):'
+    - '    print(a + b)       # Displays but doesn''t return!'

+    - 'result = add(5, 3)     # Shows 8, but result = None ❌'
+    - '```'
+    - ''
+    - '**Correct:**'
+    - '```python'
+    - 'def add(a, b):'
+    - '    return a + b       # Returns the value ✓'
+    - ''
+    - 'result = add(5, 3)     # result = 8 ✓'
+    - '```'
+    - ''
+    - '### When to Display vs Return'
+    - ''
+    - '**Use display (print) when:**'
+    - '- The function''s purpose is to show information to the user'
+    - '- You won''t need the value later'
+    - '- Example: `showWelcomeMessage()`, `displayReport()`'
+    - ''
+    - '**Use return when:**'
+    - '- The function calculates a result you''ll use later'
+    - '- You want flexibility (caller decides whether to display)'
+    - '- You''re building reusable utility functions'
+    - '- Example: `calculateTotal()`, `isValid()`, `formatName()`'
+    - ''
+    - '**Best practice:** Most functions should return values. Let the caller decide whether to display them.'
+    - ''
+    - '### Now It''s Your Turn!'
+    - 'Practice creating a function that returns a value, then using that returned value.'

+# OpenCompletion Testing Framework
+
+Comprehensive testing suite for OpenCompletion with unit tests, integration tests, functional tests, and YAML validation.
+
+## Quick Start
+
+```bash
+# Setup testing environment
+make setup
+
+# Run all tests
+make test
+
+# Run specific test types
+make test-unit
+make test-integration 
+make test-functional
+make test-validator
+make test-yaml-loading
+make test-activity-flows
+make test-battleship
+make test-guarded-ai
+make test-multiple-files
+
+# Validate YAML files
+make validate-yaml
+```
+
+## Test Structure
+
+```
+tests/
+├── unit/                    # Unit tests for individual functions
+│   ├── test_app.py         # Tests for app.py core functions
+│   └── test_activity_yaml_validator.py  # Tests for YAML validator
+├── integration/            # Integration tests for complete flows
+│   └── test_activity_processing.py      # Activity processing integration
+├── functional/             # End-to-end functional tests
+│   └── test_battleship_game_flow.py    # Complete battleship game scenarios
+└── fixtures/               # Test data and invalid samples
+    └── test_invalid.yaml   # Intentionally invalid YAML for testing
+```
+
+## Test Categories
+
+### Unit Tests (`tests/unit/`)
+
+**test_app.py** - Tests core app.py functions:
+- Utility functions (client management, S3 operations)  
+- Activity processing functions (script execution, metadata operations)
+- Response categorization and feedback generation
+- Translation and language handling
+- Navigation between activity steps
+
+**test_activity_yaml_validator.py** - Tests YAML validator:
+- YAML syntax validation
+- Schema compliance checking  
+- Metadata operations validation
+- Python code syntax checking
+- Terminal step validation
+- Logic flow validation
+
+### Integration Tests (`tests/integration/`)
+
+**test_activity_processing.py** - Tests complete activity workflows:
+- End-to-end activity processing
+- Script execution with metadata updates
+- Pre-script and post-script integration
+- Navigation between sections and steps
+- Error handling and recovery
+
+### Functional Tests (`tests/functional/`)
+
+**test_battleship_game_flow.py** - Tests complete battleship game scenarios:
+- Game setup and board generation
+- Shot processing and hit detection
+- Ship sinking logic
+- AI behavior (random, hunter, super hunter modes)
+- Win condition detection
+- Edge case handling
+
+## Features Tested
+
+### YAML Validation
+- ✅ Syntax validation
+- ✅ Schema compliance  
+- ✅ Required fields checking
+- ✅ Metadata operations (`metadata_add`, `metadata_remove`, `metadata_feedback_filter`, etc.)
+- ✅ Terminal step validation (no questions in final steps)
+- ✅ Python code syntax checking
+- ✅ Logic flow validation
+- ✅ Transition validation
+
+### Core Application Features
+- ✅ Activity loading (local files and S3)
+- ✅ Script execution with metadata manipulation
+- ✅ Response categorization using AI
+- ✅ Feedback generation
+- ✅ Multi-language support and translation
+- ✅ Step navigation and flow control
+- ✅ Error handling and recovery
+
+### Battleship Game Logic
+- ✅ Board generation and ship placement
+- ✅ Shot processing and validation
+- ✅ Hit/miss detection
+- ✅ Ship sinking logic
+- ✅ AI opponent behavior (multiple difficulty levels)
+- ✅ Win/lose conditions
+- ✅ Game state consistency validation
+
+## Running Tests
+
+### All Tests
+```bash
+make test
+```
+Runs all unit, integration, and functional tests, plus YAML validation.
+
+### Specific Test Categories
+```bash
+make test-unit          # Unit tests only
+make test-integration   # Integration tests only  
+make test-functional    # Functional tests only
+make test-validator     # YAML validator tests only
+make test-yaml-loading  # YAML loading/parsing tests
+make test-activity-flows # Activity flow tests
+make test-battleship    # Battleship game tests
+make test-guarded-ai    # Guarded AI functionality tests
+make test-multiple-files # Integration tests across all activity files
+```
+
+### YAML Validation
+```bash
+make validate-yaml      # Validate all research/*.yaml files
+```
+
+### With Coverage
+```bash
+make test-cov          # Run tests with coverage report
+```
+
+### Quick Development Testing
+```bash
+make quick             # Fast test run for development
+```
+
+## Test Configuration
+
+### Virtual Environment
+Tests run in an isolated virtual environment with all necessary dependencies:
+- pytest, pytest-cov, pytest-mock, pytest-flask
+- pyyaml, requests, flask, flask-socketio
+- gevent, eventlet, boto3, openai
+
+### Mocking Strategy
+- External APIs (OpenAI, S3) are mocked to avoid API calls during testing
+- Database operations are mocked to avoid needing a real database
+- Socket.IO events are mocked for testing real-time features
+
+### Test Data
+- **Valid YAML**: Real battleship configuration files
+- **Invalid YAML**: Intentionally broken files in `tests/fixtures/`
+- **Mock Game States**: Simulated battleship game states for testing
+- **Sample Scripts**: Python scripts for testing execution
+
+## Continuous Integration
+
+The testing framework is designed for CI/CD integration:
+
+```yaml
+# Example GitHub Actions workflow
+- name: Setup and Test
+  run: |
+    make setup
+    make test
+    make validate-yaml
+```
+
+## Development Workflow
+
+1. **Before committing**: Run `make test` to ensure all tests pass
+2. **Adding new features**: Write tests in the appropriate category
+3. **YAML changes**: Run `make validate-yaml` to check syntax
+4. **Code formatting**: Run `make format` to format and lint code
+
+## Test Coverage
+
+Current test coverage includes:
+- **YAML Validator**: 17 test cases covering all validation scenarios
+- **Core App Functions**: Comprehensive testing of utility and processing functions
+- **Activity Processing**: End-to-end workflow testing
+- **Battleship Logic**: Complete game scenario testing
+
+## Troubleshooting
+
+### Common Issues
+
+**Virtual environment not found**:
+```bash
+make clean-all  # Remove old venv
+make setup      # Create new venv
+```
+
+**Import errors**:
+```bash
+# Ensure you're in the project root directory
+cd /path/to/opencompletion
+make test
+```
+
+**YAML validation errors**:
+```bash
+# Check specific file
+venv/bin/python activity_yaml_validator.py research/problematic-file.yaml
+```
+
+## Adding New Tests
+
+### Unit Test Example
+```python
+def test_new_function(self):
+    """Test description"""
+    result = app.new_function("input")
+    self.assertEqual(result, "expected")
+```
+
+### Integration Test Example  
+```python
+def test_new_workflow(self):
+    """Test complete workflow"""
+    with patch('app.external_dependency'):
+        result = complete_workflow()
+        self.assertTrue(result.success)
+```
+
+### Functional Test Example
+```python
+def test_new_game_scenario(self):
+    """Test complete game scenario"""
+    game_state = setup_game()
+    result = play_complete_game(game_state)
+    self.assertEqual(result.winner, "user")
+```
+
+## Contributing
+
+1. Write tests for all new features
+2. Ensure tests pass: `make test`
+3. Follow existing patterns and naming conventions
+4. Update this README if adding new test categories
