Defined in:

Overview

Subscribes to ‘sql.active_record` via ActiveSupport::Notifications and records every ORM-level query with timing, status, and connection metadata.

Skips:

* schema / EXPLAIN / SAVEPOINT / TRANSACTION / nil SQL
* our own AllStak internal transport (there is none on AR side, but guarded)

Duplicates are avoided because ActiveRecord fires a single ‘sql.active_record` event per executed command — whether it’s from an ORM query, a ‘find_by_sql`, or `connection.execute`. Raw-SQL executions done through the AR connection are therefore captured via the same subscriber without double-counting.
