Key	Default	Meaning
`mode`	`regional`	`regional` masks regional indicator pairs only. `astral` additionally replaces every non-BMP character with `replacement`, which destroys legitimate output - opt in deliberately.
`replacement`	`U+FFFD`	Replacement used in `astral` mode only.
`toolResults`	`true`	Scrub tool results before they are logged.
`userMessages`	`true`	Scrub user-role messages during heal.
`assistantMessages`	`false`	Scrub assistant messages during heal.
`request`	`true`	Enable the `llm/stream` backstop.
`verbose`	`true`	Log one line per rewrite through `ctx.logger`.

Unknown keys or wrong value types fail at mount time rather than silently doing nothing.
