Sentry initialization with release + environment

Noisy error reporting without context turns into a pile of untriaged alerts. I initialize Sentry early, set the release from the git SHA, and tag the environment so I can separate staging from production. I also set a sample rate and capture only what I need—full session replays everywhere can be expensive and risky. The most useful detail I’ve learned is correlation: include a non-PII user identifier and a request id so UI errors can be matched up with backend logs. When Sentry is wired correctly, you find issues you didn’t know existed and fix them proactively instead of waiting for support tickets.
