Class Method Details

.compute_fingerprint(error_log) ⇒ Object

Derives a deterministic fingerprint from the structural identity of an error. Same source location + message + cleaned backtrace always yields the same hash, so two occurrences of the same bug map to the same group.

#record_occurrence!(backend_version: nil, client_version: nil, at: Time.current) ⇒ Object

Atomically records a new occurrence of this error. Uses a row-level lock so concurrent increments never collide.
