Investigate AI-agent analysis report on the enumerate-databases specification. This ticket tracks findings identified during a systematic review of the spec: missing test coverage, ambiguous normative language, and spec/test inconsistencies.

Missing Tests

• listDatabases SHOULD return an Iterable of database specification models or documents
• listDatabases SHOULD support filter, authorizedDatabases, and comment options
• listDatabaseNames SHOULD return an Iterable of strings
• listDatabaseNames SHOULD support filter, authorizedDatabases, and comment options
• listMongoDatabases SHOULD specify nameOnly=true when executing the listDatabases command
• MongoDatabase objects from listMongoDatabases SHOULD inherit MongoClient options (read preference, write
  concern)
• listDatabases MUST run on the primary in a replica set topology, unless directly connected to a secondary in a
  Single topology
• listDatabases MUST apply timeouts per the Client Side Operations Timeout spec — no existing tests cover this
• Results MUST NOT contain duplicate database names
• authorizedDatabases option: test all three states (unspecified/missing, false, true)
• Filter SHOULD support predicates on: name, sizeOnDisk, empty, shards

Ambiguities

• Option inheritance semantics: "MongoDatabase objects SHOULD inherit the same MongoClient options that would
  otherwise be inherited" — does this copy options at creation time or maintain a dynamic reference? What happens if
  MongoClient options change after the call?
• nameOnly with complex filter: Spec says "SHOULD specify nameOnly" but, unlike enumerate-collections, does
  not state an exception for non-name filters. Should nameOnly still be set even when a filter on other fields is
  provided?
• authorizedDatabases semantics: Three values are defined but the spec only references server documentation
  without explaining driver-level behavior for each value.

Inconsistencies

• Timeout requirement without tests: Spec REQUIRES timeout application per CSOT but the Test Plan has NO tests for
  timeout behavior.
• "Minimum Server Version: 3.6" vs pre-3.6 references: The Changelog mentions "Removed note that applied to pre-3.6
  servers" but the header still implies support starts at 3.6, while other sections discuss older behavior.

Notes

• RST stub at source/enumerate-databases.rst redirects to the .md file — can be cleaned up.
• Test Plan only has 3 test cases; more comprehensive coverage is needed.
• Good Q&A section explaining design decisions around totalSize reporting.
