Errors

Stable Tailrace error codes - what each means and where to fix the call site.

Every Tailrace error extends TailraceError with a stable code. Messages never include detected values - only entity classes, rule paths, and hashes. Each thrown message ends with a docs URL for that code.

POLICY_VIOLATIONPolicyViolationErrorA block rule matched
POLICY_INVALIDPolicyValidationErrorPolicy document failed validation
INVARIANTInvariantViolationErrorContract breach (e.g. restore at non-egress)
VAULTVaultErrorVault storage / crypto / lookup failure
RECOGNIZERRecognizerErrorRecognizer threw while scanning
NOT_IMPLEMENTEDNotImplementedErrorSpecified but not shipped yet (e.g. review)

Policy schema

Shape of a Tailrace policy document - defaults, entities, boundaries, identities, and the published JSON Schema.

POLICY_VIOLATION

A block policy matched - the sensitive value must not cross the boundary.
