🟡 Changes recommended

Several new Resource API claims are inaccurate, and one asynchronous example can outlive its component.

Once you've addressed the issues Copilot identified, you can request another Copilot review.

Pull request overview

docs/angular/rxjs-vs-resource.md:59

• This row overstates the limitation: Angular's debounced() can produce the parameter signal consumed by a resource, so a resource-based typeahead need not react to every raw keystroke. Clarify that resources do not provide an RxJS operator pipeline themselves, rather than saying they cannot support debounced fetching.

| Debounce user input before fetching      | `params` reacts to every change immediately       | [`debounceTime`](../operators/filtering/debounceTime.md)                                                            |

docs/angular/rxjs-vs-resource.md:88

• This answer repeats the incorrect claim that a resource cannot debounce. In current Angular, debounced() plus httpResource handles both the quiet period and stale-request cancellation, so it is a valid signal-native answer for a straightforward typeahead; RxJS is needed only when additional event-stream behavior justifies it.

    Because typeahead is mostly not a fetching problem. The pipeline needs debouncing (a resource's `params` reacts to every keystroke instantly) and deliberate cancellation of the settled-but-stale request. A resource does abort on params changes, but it cannot debounce, dedupe, or throttle them. The strong answer: debounce and shape the stream with RxJS, then hand the final fetch to `rxResource`, or keep `switchMap` + `toSignal`.

The Resource API comparison contains several inaccurate capability claims, and one teardown explanation remains stale.

docs/angular/signals-interop.md:116

• This rejects debounced() on the basis that it cannot cancel stale requests, but pairing its settled value with httpResource provides the same cancellation point: when the next settled parameter arrives, the resource aborts the prior HTTP request. Explain that this native pair is valid for simple typeahead and use the RxJS version when its broader stream composition is needed.

**"Why not `debounced()`?"** Angular ships a (currently experimental) `debounced()` helper that debounces a signal's value, and Signal Forms has its own field-level debouncing. For the plain search case, a debounced signal driving `httpResource` is a legitimate composition: the debounce settles the parameter and `httpResource` cancels the stale request on each change. The stream pipeline earns its place when the requirement grows past that pairing: skipping unchanged values (`distinctUntilChanged`), retry with backoff, combining several inputs, cancelling non-HTTP work (any inner Observable, not just requests), or keeping the entire policy in one reviewable pipeline. Naming that boundary, rather than defending RxJS reflexively, is the strong interview answer. Full decision guide: [RxJS or the Resource API?](rxjs-vs-resource.md)

docs/operators/combination/withLatestFrom.md:128

• The code now uses no-argument takeUntilDestroyed() in the constructor, but the numbered explanation below still documents takeUntilDestroyed(this.destroyRef), even though destroyRef was removed. Update that explanation so readers do not look for a nonexistent field.

        takeUntilDestroyed(), // constructor is an injection context
