Review Summary

The feature is well-scoped: a --message flag for push publish that includes realtime message data alongside the push extras when publishing via --channel. The validation logic is correct (errors if --message used without --channel, warns if a direct recipient overrides --channel). Two issues worth addressing:

1. messageData: true in JSON output omits actual content

File: src/commands/push/publish.ts, lines 293–303

...(flags.message ? { messageData: true } : {}),

The JSON result confirms that a message was included (messageData: true) but drops the actual content that was sent. A programmatic consumer using --json for auditing or pipeline verification can't tell what data was published — just that something was.

The fix is straightforward: emit the actual parsed value instead of the boolean sentinel:

...(flags.message ? { messageData: publishMessage.data } : {}),

publishMessage.data is already set at this point (lines 283–288), so this costs nothing and makes the JSON output self-describing.

2. Non-standard test describe block

File: test/unit/commands/push/publish.test.ts, line 201

describe("--message flag (realtime message data)", () => {

This is a sibling of "functionality" and "error handling" but doesn't match any of the 5 required standard block names. The new test cases belong in the existing describe("functionality" block (happy-path tests) and describe("error handling" block (the "fail without --channel" case). The test coverage itself is solid — it's just the placement that needs adjusting.

Both changes are small. The JSON output issue is the more meaningful one since it affects consumers relying on --json for automation.
