**SSRF via redirect bypass**

The hostname blocklist (lines 269–292) is applied to the *original* URL only. Because `redirect: "follow"` is used, an open redirect on any public host (e.g. `https://public.example.com/r?url=http://169.254.169.254/...`) will cause the gateway to silently forward requests to private/metadata addresses that the blocklist is meant to block. The content-type filter limits data exfiltration but does not prevent the gateway from making the request itself, which is still a Server-Side Request Forgery.

Use `redirect: "manual"` (or `redirect: "error"`) and re-validate the `Location` header hostname before following, or simply refuse all redirects:

```typescript
upstream = await fetch(targetUrl, {
  signal: controller.signal,
  redirect: "manual",   // never follow automatically
  headers: {
    Accept: "image/*",
    "User-Agent": "OpenClaw-ImageProxy/1.0",
  },
});

if (upstream.status >= 300 && upstream.status < 400) {
  res.statusCode = 403;
  res.setHeader("Content-Type", "text/plain; charset=utf-8");
  res.end("Forbidden: redirects are not allowed");
  return true;
}
```

How can I resolve this? If you propose a fix, please make it concise.

**Private method accessed via unsafe cast**

`_rewriteFile()` is a private internal of `SessionManager` reached through `as unknown as { _rewriteFile(): void }`. If the upstream library renames or removes this method, the cast will still compile but the runtime call will throw `TypeError: manager._rewriteFile is not a function`, surfacing as a confusing `UNAVAILABLE` error for the fork caller.

If immediate file persistence is needed, consider asking the library to expose a public `flush()` / `save()` API, or document this as a workaround with a TODO to upstream the feature.

Comment:
**New `provider` field is not merged on re-registration**

The PR adds `provider` to `AgentRunContext` and `server-chat.ts` relies on `runContext.provider === "cron-event"` to suppress heartbeat output. However the re-registration merge path only updates `sessionKey`, `verboseLevel`, `isControlUiVisible`, and `isHeartbeat` — `provider` is never updated here. If `registerAgentRunContext` is called a second time for the same `runId` with a `provider` value, the existing context retains whatever `provider` (or lack thereof) was set on first registration.

This is consistent with how the first-registration spread works, but the asymmetry with `isHeartbeat` (which *is* updated on re-registration) may be unintentional. If cron-event runs are always registered with `provider` on their very first call, this is fine; if any code path calls `registerAgentRunContext` again with `provider: "cron-event"` expecting it to take effect, the suppression check in `server-chat.ts` will silently fail.

**In-memory `manager.branch()` not persisted before `chat.send`**

When `entryId` is provided, `manager.branch(targetEntry.id)` updates the in-memory manager's leaf position, but nothing is written to the transcript before `chatHandlers["chat.send"]` is called. `chat.send` will open a *new* `SessionManager` from the same file, so it will see the transcript's natural (last-appended) leaf — not the branch set here.

The regenerate handler handles this correctly by writing a persistent marker entry:
```ts
manager.appendCustomEntry("openclaw:branch-regenerate", { ... });
```

The continue handler with `entryId` relies entirely on `activeLeafId` in the session store being respected by `chat.send`. If `chat.send` derives history from `SessionManager.getLeafId()` (the transcript's natural leaf) rather than from `activeLeafId`, the continue-from-entry feature will silently use the wrong branch context.
