- Around line 105-131: The logs in get_invocation_yaml_selector currently print
full invocation_args_dict and config.args (via invocation_args_dict and
config.args) at info level, which may expose secrets; change these log calls to
use debug-level only and redact sensitive fields (e.g., --vars, tokens,
passwords, emails, ENV-derived secrets) before logging by either omitting those
keys or replacing their values with "[REDACTED]"; keep all other debug messages
(e.g., when returning selector, selector_name, or INVOCATION_COMMAND matches)
intact and ensure logging uses the same debug/info flagging as the surrounding
module.

{}).get("test_sample_row_count")) at debug level; update the {% do log(...) %}

Don’t log full flattened_test.meta at info level.

Potential KeyError when referenced_columns is missing from meta.
Line 35 uses meta['referenced_columns'] which will raise a KeyError if the key doesn't exist in the unified meta dictionary. This would prevent the warning at line 70 from ever being reached.

Update cache path to target/db/schemas and add error logging.
The cache path in dbt-fusion 2.0.0-preview is stored at target/db/schemas/, not target/schemas/. The current code targets the wrong directory and silently ignores failures, making flakes undiagnosable.

Captured output is lost on failure.
When subprocess.run fails with check=True, a CalledProcessError is raised but the captured stdout/stderr aren't logged, making it difficult to diagnose why dbt clean failed. Consider handling the error to surface the output.
