RECOGNIZER

What it means

RecognizerError (code: RECOGNIZER). A detection engine threw during scan.

Message shape

<reason> → https://tailrace.dev/docs/reference/errors/RECOGNIZER

Common causes

1. Custom recognizer bug.
2. Optional Tier 1 engine misconfiguration (should degrade to Tier 0 with a warning - if you see this, the recognizer threw instead of failing open).

Fixes

1. Fix or remove the custom recognizer.
2. Ensure Tier 1 optional models fail open per product rules - never crash the host for a missing model.

Safe to catch?

For block-configured entity classes, fail closed if detection cannot run. For availability of optional Tier 1, prefer degrade-to-Tier-0.
