Investigate AI-agent analysis report on the command-logging-and-monitoring 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

• All commands in a single bulk write operation MUST share the same operationId — tests verify structure but not
  that all commands in a batch share identical operationId
• OP_MSG document sequences MUST be represented as a BSON array in CommandStartedEvent.command — tests exercise
  bulk insert but don't explicitly assert the array representation
• Default write concern MUST be omitted from published command — tests cover unacknowledged writes (w:0) but no
  test verifies that a command with default write concern omits it
• serviceId MUST appear in all three event types (Started, Succeeded, Failed) — likely only tested in one
• Heartbeat command exclusion from logs — no-handshake-messages.yml tests handshake but no equivalent test for
  heartbeat commands
• Server-side CommandFailedEvent redaction: errmsg and extra fields MUST be removed, code/codeName/errorLabels
  kept — tests focus on auth commands but not general server-error redaction

Ambiguities

• hello with speculativeAuthenticate redaction scope: Does presence of speculativeAuthenticate require
  redacting the entire hello command, or only the speculativeAuthenticate field?
• Unacknowledged write reply fields: Spec requires {{ { ok: 1 }

  }} reply for unacknowledged writes but doesn't specify
  whether n or other fields may/must be present.

• connectionId structure flexibility: "For languages without ConnectionId, return driver equivalent which MUST
  include server address and port. The name is flexible." Tests expect specific structure; spec should tighten or
  provide canonical JSON example.
• operationId generation trigger: Marked OPTIONAL in all event types but spec doesn't define which operations MUST
  include it. Only describes bulk operations; no guidance for single commands.

Inconsistencies

• Guarantees section vs. test coverage: Spec guarantees every CommandStartedEvent has a correlating Succeeded or
  Failed, and requestId matches — tested for specific operations but not systematically across all CRUD + retry
  scenarios.
• Logging vs. Monitoring parity: Spec says drivers MAY implement logging via event subscriber (same mechanism).
  Tests have separate logging and monitoring directories, potentially masking functional divergence between the two.

Notes

• 10 logging + 15 monitoring test files. Strong coverage for CRUD, error cases, and redaction.
• Prose tests (3 items: truncation limit, explicit truncation, multi-byte codepoints) are well-defined and placed in
  README.
• All tests in unified format; legacy format migration completed in 2022.
