# Custom Error Leaks Keywords for TMI CATS Fuzzing
#
# This file excludes standard OAuth 2.0 error terms that legitimately appear
# in 401/403 responses per RFC 6749. These are NOT security vulnerabilities
# or information leaks - they are required protocol responses.
#
# Excluded terms (appear in RFC 6749 responses):
#   - Unauthorized (standard 401 response)
#   - Forbidden (standard 403 response)
#   - InvalidToken (OAuth error code)
#   - InvalidGrant (OAuth error code)
#   - AuthenticationFailed (OAuth error description)
#   - AuthenticationError (OAuth error description)
#   - AuthorizationError (OAuth error description)
#
# All other error keywords from CATS defaults are retained below.
