Reopening the add-project folder picker rendered a cached directory listing and never refetched, so folders created outside T3 Code stayed invisible for up to 5 minutes. Root cause: browse query atoms outlive the picker through their idle TTL, and the swr wrapper only re-checks staleness when an atom node is rebuilt, so resubscribing to a warm node serves the frozen value and revalidateOnMount never fires (details in #11476).

The fix adds a small hook that refreshes once when a picker mounts onto a warm atom that already holds settled data. Cold atoms keep their single initial fetch, so there is no double fetch and no polling. Applied to the browse query on web (command palette) and mobile (add-project folder browser), which share the same atom family.

Fixes #11476

Before and after

Steps in both captures: browse /tmp/t3-demo/ in the picker, close it, mkdir /tmp/t3-demo/Fun outside the app, reopen the picker at the same path.

Before (main) After (this branch)
before: Fun missing after reopen after: Fun listed after reopen

Verification

  • Captured above against a real dev server in a worktree with isolated .t3 state, on this branch and on main for the before shot.
  • vp run --filter @t3tools/web typecheck and --filter @t3tools/mobile typecheck clean.
  • Targeted vp lint on the touched files: no new warnings.

  • Bug Fixes
    • Filesystem browsing now refreshes cached results when reopening the add-project flow or command palette.
    • Recent results remain available without an unnecessary reload, while older or failed requests are refreshed to better reflect the current filesystem state.

🟠 High projects/AddProjectScreen.tsx:773

Reopening the picker does not retry a cached browse failure, so a transient filesystem or connection error remains displayed until the atom's five-minute idle TTL expires. useWarmEnvironmentQueryRevalidation only refreshes non-waiting Success results and marks the atom handled before that check; refresh any non-waiting settled result, including Failure, so reopen revalidates cached errors.

Cached failures are never revalidated. Failure is also a settled AsyncResult (the shared runtime defines SettledAsyncResult as Success | Failure), but this condition only refreshes successful values and the ref is set before it. Thus, if a browse RPC fails, closing and reopening the picker within its five-minute idle TTL remounts the cached error, marks that atom as handled, and sends no retry request; the picker remains unusable until eviction or a manual refresh. Refresh any non-waiting settled result (or do not mark failures handled) so transient filesystem/connection errors retry on reopen.

Fixed in 560723d. The hook now refreshes any settled result instead of only successes, so a cached browse failure retries on reopen rather than sticking for the idle TTL. Successes younger than a short freshness window are skipped so navigation prefetches are not fetched twice (see the sibling CodeRabbit thread).

Approvability

Verdict: Would Approve

Macroscope's review found this PR approvable — This is a localized bug fix that refreshes warm filesystem listings when the existing folder pickers reopen, without schema, infrastructure, or sensitive-path changes. A separate unresolved High-severity issue remains for cached browse failures not being retried, which blocks approval under the repository threshold.

Not approved because:

📝 Walkthrough

Walkthrough

The query state modules add freshness-aware warm-cache revalidation. The mobile folder browser and web command palette use the hook to refresh stale or failed filesystem browse queries when their flows reopen.

Changes

Filesystem browse revalidation

Layer / File(s) Summary
Warm revalidation hook
apps/mobile/src/state/query.ts, apps/web/src/state/query.ts
Adds a 500 ms freshness window. The hook skips waiting, initial, and fresh success results, and refreshes stale successes or failures once per atom.
Picker browse integration
apps/mobile/src/features/projects/AddProjectScreen.tsx, apps/web/src/components/CommandPalette.tsx
Passes the filesystem browse atom to the revalidation hook when the add-project flow or command palette uses filesystem browsing.

Comment thread apps/mobile/src/state/query.ts Outdated
Review follow-up: the warm-mount revalidation only refreshed cached
successes, so a transient browse failure stayed rendered for the whole idle
TTL, and it also refreshed listings the picker's own navigation had
prefetched moments earlier, doubling every click-navigation request.

Refresh any settled result, but skip successes younger than a short
freshness window. Verified in the dev client: click navigation mounts the
prefetched atom at ~35ms age (one request), a reopened picker mounts
seconds-old data and revalidates.
