Struct AuditStore 

pub struct AuditStore { /* private fields */ }

Append-only audit store backed by a JSON file.

In a future phase, this will be backed by LanceDB for vector search capabilities. For now, JSON file storage is sufficient and simple.

Implementations

impl AuditStore

pub fn new(path: &Path) -> Self

Create a new audit store at the given path.

pub fn new_memory() -> Self

Create an audit store using a temporary file (for tests).

pub fn log_action(&self, action: &Action, status: &str, output: &str)

Convenience: log an action with minimal params.

pub fn log(&self, params: AuditLogParams) -> Result<AuditEntry, AuditError>

Append a new entry to the audit log.

Automatically computes the hash chain linkage from the last entry.

pub fn load_all(&self) -> Result<Vec<AuditEntry>, AuditError>

Load all audit entries from the log file.

pub fn query_by_workflow( &self, workflow_id: &str, ) -> Result<Vec<AuditEntry>, AuditError>

Query entries by workflow ID.

pub fn query_by_time_range( &self, from: DateTime<Utc>, to: DateTime<Utc>, ) -> Result<Vec<AuditEntry>, AuditError>

Query entries within a time range.

pub fn recent(&self, limit: usize) -> Result<Vec<AuditEntry>, AuditError>

Get the most recent N entries.

pub fn verify_chain(&self) -> Result<bool, AuditError>

Verify the integrity of the entire hash chain.

Returns Ok(true) if the chain is valid, or an error describing where the chain was broken.
