pub fn from_default() -> Result<Self, String>

Create a RecallEcho using the default path resolution (RECALL_ECHO_HOME env var or current working directory).

pub fn entity_root(&self) -> &Path

Entity root directory.

pub fn memory_dir(&self) -> PathBuf

Memory directory: {entity_root}/memory/

pub fn memory_file(&self) -> PathBuf

Path to MEMORY.md.

pub fn ephemeral_file(&self) -> PathBuf

Path to EPHEMERAL.md.

pub fn conversations_dir(&self) -> PathBuf

Path to conversations directory.

pub fn archive_index(&self) -> PathBuf

Path to ARCHIVE.md index.

pub fn consume_content(&self) -> Result<Option<String>, String>

Read EPHEMERAL.md content without clearing it. Returns None if the file doesn’t exist or is empty.

pub fn is_initialized(&self) -> bool
