>
> **Action Items & Next Steps:**
> - **Immediate:** Rotate API tokens and monitor memory limits on [Datadog Cluster Dashboard](https://datadog.com/dashboard/k8s).
> - **Follow-up:** Add automated heap memory alerts in @sre-team.
> - ~~Decommission legacy ingestion workers~~ (Completed)
>
> **Key Code Patch:**
> ```typescript
export function processChunk(chunk: Buffer) {
// Fix: Explicitly release buffer memory reference after flushing
writeToStream(chunk);
chunk.fill(0);
}
```

What this converter does not do (yet), and what to do instead.
- User mentions keep only the display name if Slack included one (<@U123|name>); bare IDs cannot be resolved.
- Emoji shortcodes such as :tada: stay as text; most Markdown viewers do not turn them into emoji.
- Attachments, threads, reactions and Block Kit layouts are not part of copied text, so they are not converted.
- Slack's own export (JSON) is not supported; paste message text instead.
