The work, as it ships

Shipped, and verified

Every line traces back to real commits, releases, and deploys, not a text box. The newest arrives at the top, stamped with its source.

Currently

  • The decision

    Chose a token-bucket rate limiter to bound burst traffic without dropping legitimate retries

    The reasoning

    Weighed a fixed-window counter against a token bucket and went with the bucket: it absorbs short retry bursts while still holding the average rate, so a client retry storm degrades gracefully instead of hard-blocking real users.

    Captured from an AI coding session, grounded to the commit it shipped in.
