4b9ffb5ddf docs: Update architecture and add new documentation for LLM and MCP
- Enhanced `ARCHITECTURE.md` with details on LLM models for work (Llama 3.1 70B Q4) and family agents (Phi-3 Mini 3.8B Q4).
- Introduced new documents:
  - `ASR_EVALUATION.md` for ASR engine evaluation and selection.
  - `HARDWARE.md` outlining hardware requirements and purchase plans.
  - `IMPLEMENTATION_GUIDE.md` for Milestone 2 implementation steps.
  - `LLM_CAPACITY.md` assessing VRAM and context window limits.
  - `LLM_MODEL_SURVEY.md` surveying open-weight LLM models.
  - `LLM_USAGE_AND_COSTS.md` detailing LLM usage and operational costs.
  - `MCP_ARCHITECTURE.md` describing the Model Context Protocol architecture.
  - `MCP_IMPLEMENTATION_SUMMARY.md` summarizing MCP implementation status.

These updates provide comprehensive guidance for the next phases of development and ensure clarity in project documentation.

3b8b8e7d35 Evaluate and Select Wake-Word Engine (#3)
# Ticket: Evaluate and Select Wake-Word Engine

## Ticket Information

- **ID**: TICKET-005
- **Title**: Evaluate and Select Wake-Word Engine
- **Type**: Research
- **Priority**: High
- **Status**: Backlog
- **Track**: Voice I/O
- **Milestone**: Milestone 1 - Survey & Architecture
- **Created**: 2024-01-XX

## Description

Evaluate wake-word detection options and select one:
- Compare openWakeWord and Porcupine for:
  - Hardware compatibility (Linux box/Pi/NUC)
  - Licensing requirements
  - Ability to train custom "Hey Atlas" wake-word
  - Performance and resource usage
  - False positive/negative characteristics

## Acceptance Criteria

- [ ] Comparison matrix of wake-word options
- [ ] Selected engine documented with rationale
- [ ] Hardware requirements documented
- [ ] Licensing considerations documented
- [ ] Decision recorded in architecture docs

## Technical Details

Options to evaluate:
- openWakeWord (open source, trainable)
- Porcupine (Picovoice, commercial)
- Other open-source alternatives

Considerations:
- Custom wake-word training capability
- Resource usage on target hardware
- Latency requirements
- Integration complexity

## Dependencies

- TICKET-004 (architecture) - helpful but not required
- Hardware availability for testing

## Related Files

- `docs/WAKE_WORD_EVALUATION.md` (to be created)
- `ARCHITECTURE.md`

f8ff2d3a55 feat(tts): Evaluate TTS options and select Piper
This commit completes the evaluation of Text-to-Speech (TTS) options
as described in TICKET-013.

- Creates a detailed  document comparing Piper,
  Mimic 3, and Coqui TTS.
- Recommends Piper for initial development due to its performance and
  low resource usage.
- Updates  to reflect the decision and points to the
  new evaluation document.
- Moves TICKET-013 to the 'done' column.

f7dce46ac9 # Complete Foundational Tickets: Repository Structure, Privacy Policy, and Safety Constraints (#1)
# Complete Foundational Tickets: Repository Structure, Privacy Policy, and Safety Constraints

## Summary

This PR completes the foundational planning tickets (TICKET-002, TICKET-003, TICKET-004) by:
1. Defining the repository structure with detailed documentation
2. Establishing a comprehensive privacy policy
3. Documenting safety constraints and boundaries for work/family agent separation

## Related Tickets

-  TICKET-002: Define repository structure
-  TICKET-003: Privacy and safety constraints
-  TICKET-004: High-level architecture

All tickets have been moved from `backlog/` to `review/` to mark completion.

## Changes

### 1. Enhanced ARCHITECTURE.md

**Repository Structure Section:**
- Added detailed descriptions for `home-voice-agent` mono-repo structure
- Documented `family-agent-config` configuration repository
- Added inline comments explaining each directory's purpose
- Added `infrastructure/` directory for deployment scripts, Dockerfiles, and IaC
- Clarified separation of concerns between mono-repo and config repo

**Documentation References:**
- Added links to new privacy policy and safety constraints documents in the "Getting Started" section

### 2. New Documentation: PRIVACY_POLICY.md

Establishes the core privacy principles for the Atlas project:

- **Local Processing**: All ASR/LLM processing done locally, no external data transmission
- **External API Exceptions**: Explicitly documents approved external APIs (currently only weather API)
- **Data Retention**: Configurable conversation history retention (default 30 days)
- **Data Access**: Local network only with authentication requirements

### 3. New Documentation: SAFETY_CONSTRAINTS.md

Defines safety boundaries and constraints:

- **Strict Separation**: Work and family agents must remain completely isolated
- **Forbidden Actions**: Family agent cannot access work files, execute shell commands, or install packages
- **Path Whitelists**: Tools restricted to explicitly whitelisted directories
- **Network Access**: Local network by default, external access only for approved tools
- **Confirmation Flows**: High-risk actions require user confirmation
- **Work Agent Constraints**: Work agent also restricted from accessing family data

## Impact

This PR establishes the foundational documentation that will guide all future development:

- **Privacy-first approach**: Clear policy ensures all development respects user privacy
- **Safety boundaries**: Explicit constraints prevent accidental data leakage between work/family contexts
- **Architecture clarity**: Detailed repository structure provides roadmap for implementation

## Testing

- [x] Documentation reviewed for clarity and completeness
- [x] All ticket requirements met
- [x] Cross-references between documents verified

## Next Steps

With foundational tickets complete, development can proceed on:
- Voice I/O track (wake-word, ASR, TTS)
- LLM Infrastructure track (model selection, server setup)
- Tools/MCP track (MCP foundation, tool implementations)
- Clients/UI track (Phone PWA, web dashboard)
- Safety/Memory track (boundary enforcement, memory implementation)

---

**Commit Message**: My to-do list is clear. I've finished the foundational tickets per the guide. I'm ready for what's next and will notify the user.
