Review	File	Issue	Note
Code	bin/fetch-logpush-datasets.ts line 101	File read into memory for hashing	The author says the archive is a small build-time asset (~32 KiB), so a single bounded read after download is fine and streaming would add asynchronous error-handling complexity to a six-line change without a meaningful memory benefit; they will revisit if the archive grows.

Commands

Only codeowners can run commands. Post a comment with the command to trigger it.

Command	Description
/review	Runs a review now. Incremental if a prior review exists, full if not.
/full-review	Re-reviews the entire PR diff from scratch, ignoring incremental history. Useful after a rebase, when you want a fresh review, or if the bot gets out of sync and reports issues that no longer exist.
/ignore-review-limit	Permanently lifts the 2-review automatic limit for this PR. Future pushes will trigger reviews as normal.
/disable-auto-review	Stops automatic reviews from triggering on future pushes to this PR. Codeowners can still run /review or /full-review manually.
/rebase	Rebases the PR branch against production. On conflict, attempts to resolve automatically using AI. Stops with an explanation if confidence is not high enough.

CR-1ea197232306: Skipping this suggestion. The archive is a small build-time documentation asset, currently about 32 KiB, and hashing requires one bounded read after download. Streaming would add asynchronous error-handling complexity to a six-line change without a meaningful memory benefit. We can revisit this if the archive grows materially.
