Remarks
This is the single implementation the whole feature turns on. The derived path and the read path both redact through it, so a citation drawn from a redacted chunk lands on the same redacted text when a reader opens the message; two implementations would drift the moment either one gained a rule about ordering, overlap, or truncation.
The result is reproducible. For a given text, plan, and set of detector revisions, the redacted text is byte-identical on repeat: scanners run in a fixed order, findings are sorted before they are applied rather than applied in the order they arrived, and overlapping regions merge under a rule that does not depend on which detector answered first.
It fails closed. A detector that is absent, slow past the configured budget, broken, or reporting a region outside the text it was handed refuses the operation rather than returning the text unredacted. The one thing that never raises a failure is the analyzed ceiling: text beyond it is dropped from the result rather than passed on, so an over-long input costs the remainder instead of the whole operation.
