## A
**Answer Mode** - Configuration that determines how the bot responds to user queries (direct LLM, with tools, documents only, etc.)

**Argon2** - Password hashing algorithm used for secure credential storage (winner of Password Hashing Competition)

**AST** - Abstract Syntax Tree, the compiled representation of BASIC scripts used for execution

**Authentication Flow** - Process of verifying user identity through credentials and establishing a session

## B
**BASIC** - The scripting language used in .gbdialog files for creating conversational flows

**Bot Authentication** - Process of verifying a bot's credentials before allowing access

**BotSession** - A single conversation instance between a user and bot, maintaining context and history

## C
**Collection** - A group of documents in a knowledge base that are indexed together for semantic search

**Context** - The current state and history of a conversation that influences bot responses

## D
**Dialog** - A conversation script written in BASIC that defines bot behavior and flow

## E
**Embedding** - A vector representation of text used for semantic similarity comparisons

**Qdrant** - Vector database used for semantic search and embeddings

## S
**Session** - See BotSession

**Session Token** - Unique identifier issued after authentication that validates subsequent requests

**Semantic Search** - Search method that finds content based on meaning rather than just keywords
