 - Always `defer sentry.Flush(2 * time.Second)` in `main()`; call it explicitly before `os.Exit()`
 - Clone the hub before passing it to goroutines: `hub := sentry.CurrentHub().Clone()`
 - Use `WithScope` for one-off context; use `ConfigureScope` for persistent session context
-- Prefer `SetTag` or `SetContext` over `SetExtra` for error event data (`SetExtra`/`SetExtras`/`RemoveExtra` are deprecated)
+- Use `SetTag` or `SetContext` for error event data — `SetExtra`/`SetExtras`/`RemoveExtra` were **removed in v0.34.0** and no longer compile
 - Use `SetAttributes` / `RemoveAttribute` to attach typed key-value pairs to logs and metrics (attributes do not appear on error events)
 - Use `BeforeSend` to strip PII — never send raw email/IP unless `SendDefaultPII: true` is intentional
 - Set `MaxErrorDepth` to a sensible value (5–10) for deeply wrapped error chains
