# bloomberg — Spectral ruleset (strengthened)
# Plain Spectral. Existing hand-authored rules preserved; measured rules added
# from this provider's own OpenAPI conventions by strengthen_ruleset.py,
# then self-validated against the spec.

# Provenance:
#   - operationid-casing: camel @ 100% (n=9)
#   - schema-names-casing: pascal @ 100% (n=4)
#   - error-schema-defined: ErrorMessage
#   - merge: kept 7 existing, added 3 measured, upgraded 0
#   - added: operationid-casing, schema-names-casing, error-schema-defined
