### Added
#### Multi-Vault Support (Phase 008-010)
- **Global Configuration**: `~/.config/palace/config.yaml` for managing multiple vaults

- **`palace_vaults` Tool**: List and manage configured vaults
#### Intent-Based Storage (Phase 011)
- **`palace_store` Tool**: Store knowledge by expressing intent (WHAT), not path (WHERE)
- **`palace_check` Tool**: Check for existing knowledge before creating (check-before-store pattern)
- **`palace_improve` Tool**: Intelligent note updates with multiple modes
- **Knowledge Layer Model**: Three-layer organization (Technical, Domain, Contextual)
- **Path Resolution Engine**: Automatic path determination from intent
- **Stub System**: Create placeholder notes for unknown technologies
- **Retroactive Linking**: Update existing notes when new related content is created
#### Atomic Note System (Phase 012)
- **Auto-Splitting**: Automatically split large content into hub + child notes
- **Hub Pattern**: Navigation hubs with `_index.md` files

- **Section Extraction**: Large sections become separate notes
#### Standards System (Phase 013)
- **`palace_standards` Tool**: Load binding standards for AI behavior
- **`palace_standards_validate` Tool**: Validate notes against standards
- **Binding Levels**: `required`, `recommended`, `optional`
- **Cross-Vault Standards**: Load standards from dedicated vault
- **AI Acknowledgment**: Required standards must be acknowledged
#### AI Support Tools (Phase 014)
- **`palace_clarify` Tool**: Generate clarifying questions for incomplete context
- **Context Detection**: Detect technologies, projects, clients, scope, domains
- **Confidence Scores**: All detections include confidence (0-1)
- **Missing Context Identification**: Know what information is needed
- **Question Generation**: Contextual questions with options and hints
#### Documentation (Phase 015)
- **API Reference**: Complete tool documentation (`docs/API.md`)
- **Configuration Guide**: All configuration options (`docs/CONFIGURATION.md`)
- **AI Behavior Guide**: Protocols for AI assistants (`docs/AI-BEHAVIOR.md`)
- **Examples**: Configuration and standard note examples (`examples/`)
### Changed
- **Frontmatter Schema**: Added `status`, `domain`, `palace` block
- **Index Schema**: New tables for stubs, technology mentions, authors
- **Note Format**: Support for hub notes and atomic note hierarchy
### Removed
- **`palace_remember`**: Removed before initial release (use `palace_store`)
- **`palace_update`**: Removed before initial release (use `palace_improve`)
- **`PALACE_VAULT_PATH`**: Legacy env var removed (use `PALACE_VAULTS` instead)
- **Schema Migrations**: Removed unused migration code for clean initial release
