v0.11.1

• Fixed. A readOnly property is now dropped from a request schema — and a
  writeOnly one from a response schema — under additionalProperties as it
  already was under properties, items and the composition keywords. A
  document that keyed its items by name instead of listing them kept the
  property required, so a legal request was reported as
  request.body.schema. not is deliberately left alone: neither
  specification says what a readOnly property means under a negation.
  (#130)
• Fixed. Contract::requireMatch() names the request path in its
  UnknownOperation message, not the whole URI: a query string and userinfo
  are where a credential travels, and the unmatched violation had printed
  the path alone for exactly that reason. The request.server.mismatch
  diagnostic renders scheme, host and port instead of the PSR-7 authority,
  which carries userinfo the comparison never reads. (#131)
• Fixed. A Media Type Object declaring the boolean schema false on a
  non-JSON response body now produces response.body.schema, as the request
  side and the JSON branch already did; the opaque branch had read false as
  "no schema declared" and passed the body. (#132)
• Fixed. Contract::accepts() and SchemaCheck::accepts() raise
  InvalidContract for a schema they cannot read — one that cannot be
  JSON-encoded (NAN/INF, malformed UTF-8, more than 512 levels), or a list
  in place of an object — where the first leaked a raw JsonException and
  the second was read as the empty schema and accepted every value. A schema
  out of a document meets neither: the compiler settles both at load time.
• Documentation. Four boundaries are now written down: a JSON body deeper
  than 64 levels is reported as *.body.json, which the decoder cannot tell
  from malformed JSON; the schema compilation cache never evicts, so a
  SchemaCheck is one per document; a hand-passed schema may $ref only
  inside itself; and securitySchemes() checks flows and the URL fields
  for shape, not for content. llms.txt no longer names the
  Contract::MAX_* constants that 0.9.0 replaced with Limits.
