Replace any at the observer boundary.

AnyObserver only needs to store an opaque snapshot result. any disables type checking without improving the bridge API. Use unknown for this internal boundary.

Proposed change

-import type { LiveQuerySnapshot } from '`@tanstack/db`'
-
 type AnyObserver = {
-  getSnapshot: () => LiveQuerySnapshot<any, any>
+  getSnapshot: () => unknown
   subscribe: (listener: () => void) => () => void
 }

As per coding guidelines, “Avoid using any types; use unknown instead when the type is truly unknown.”

Document isPending and latest.

The PR adds isPending and latest to async memo accessors. This overview and the accessor-property list do not describe either property. Add both properties and state their loading and refresh behavior.

Add cleanup and notification-order coverage.

Add a test with an empty initial collection. Add a test that disposes the Solid root, then invokes the captured observer listener and confirms that the memo does not run again. Add rapid observer notifications before one flush() and confirm that the memo reads the latest snapshot.

As per coding guidelines, “Test corner cases including: empty arrays/sets” and “async race conditions.”

Release the patched promise even when the assertions fail.

The test replaces newLiveQuery.toArrayWhenReady with a promise that only resolveNewLiveQuery!() settles. If the waitFor block at Line 2895 rejects, that line never runs, the promise stays pending, and the non-null assertion can also fail if the patched method was never called. Resolve it in a finally block and restore the original method.

♻️ Proposed refactor

-      expect(new Set(rendered.result().map((person) => person.id))).toEqual(
-        new Set([`new-only`, `same`]),

Replace the fixed 50 ms sleeps with a readiness wait.

Each case waits 50 ms before measuring. On a slow machine the collection can still be loading, which makes the recorded medians inconsistent. Wait for the query readiness flag instead.

♻️ Suggested helper

async function whenReady(query: { isReady: boolean }, timeoutMs = 5000) {
  const deadline = Date.now() + timeoutMs
  while (!query.isReady) {
    if (Date.now() > deadline) throw new Error(`collection not ready`)
    await new Promise((resolve) => setTimeout(resolve, 5))
    flush()
  }

Inline comments:
In @.changeset/solid-v2-wholesale-refactor.md:
- Line 92: Update the benchmark headings under the “## Performance” section,
including “Initial All-Row Mount” and the headings at the referenced locations,
from “####” to “###” to maintain valid Markdown heading hierarchy.

In `@packages/solid-db/src/external-source.ts`:
- Around line 37-40: Update the installation precondition documentation near
trackSnapshot to state that installation must occur before a Solid computation
first calls trackSnapshot; remove the inaccurate requirement involving
useLiveQuery or createLiveQueryObserver calls.

In `@packages/solid-db/src/useLiveQuery.ts`:
- Around line 434-445: Update the status:error listener in the currentCollection
setup to accept the event payload and assign its actual error value to
collectionError before setting error status, using the confirmed status:error
payload field. Preserve the cancelled guard and the existing toArrayWhenReady
rejection handling.
- Around line 498-505: Update the lazy sync branch in useLiveQuery so it
iterates currentCollection’s key-value pairs and stores each row using its
collection key, matching applySnapshot’s state key space; do not use value.$key
for this path.

In `@packages/solid-db/tests/benchmark.bench.ts`:
- Around line 107-122: Update the Initial mount benchmark around createRoot and
useLiveQuery so the promise always settles, including when query() throws during
loading. Keep the root alive until the query is ready, resolve only after
readiness, and dispose the root after resolution rather than immediately.
- Around line 1-6: Rename the benchmark file from .bench.ts to .test.ts so the
existing package test command collects and executes its describe/it cases. Keep
the current test structure unchanged; do not add a separate benchmark command or
convert the cases to bench().

In `@packages/solid-db/tests/useLiveQuery.test.tsx`:
- Around line 3060-3082: Update the test setup around source2 and the related
assertions near the additional occurrence so source2 contains a different number
of rows than source1. Preserve the pre-readiness expectation and make the
post-secondMarkReady assertion expect source2’s distinct count, ensuring
latest() updates observably.

Replace the fixed timeout with a state-based wait.

Line 1158 waits 10 ms and then asserts the null collection. The assertion depends on wall-clock timing, so it can flake on a loaded CI runner. Use waitFor so the test waits for the observable state instead.

♻️ Proposed change

         // Disable the query again
         setEnabled(false)
-        await new Promise((resolve) => setTimeout(resolve, 10))
-
-        expect(rendered.result.collection).toBeNull()
+        await waitFor(() => {
+          expect(rendered.result.collection).toBeNull()
