@claude please review again

[erinz2020]

@claude You are reviewing a code change as a senior engineer in an existing production codebase.

Your goal is to find only the most important issues that should realistically be addressed before merge.

Review principles:

Prioritize correctness, reliability, data flow, async behavior, state consistency, and real maintainability risks.
Do not comment on personal preference, code style, naming, or optional refactors.
Do not propose architecture changes unless the current implementation is clearly dangerous or broken.
Respect existing project conventions and favor minimal changes.
Do not invent missing requirements.
Be conservative: if something is acceptable, do not flag it.
Pay special attention to:

null / undefined access
React effect dependency mistakes
stale closures
race conditions
duplicate or inconsistent state
controlled/uncontrolled form issues
loading / error / empty-state logic
accidental rerenders with real impact
incorrect assumptions around async requests, polling, or derived data
Output:

Start with one line only:

"No merge-blocking issues found"
or "Found X important issues"
Then provide up to 3 issues only.

For each issue, use:

Severity: blocker | high | medium
Location: file / function / component
Problem:
Impact:
Minimal fix:
Do not include praise.
Do not include optional improvements.
Do not include “consider”, “might”, or “could” comments unless there is a concrete risk.

Found 2 important issues

---

Issue 1

• Severity: medium

• Location: EncounterSearch.jsx — useEffect([perPage])

• Problem: When perPage changes, resetGallery() clears currentPageItems, start, assetOffset, and galleryExhausted, but pg() is never called afterward. In GalleryView, canFetchNextPage evaluates to false after a reset (because currentPageItems.length = 0 < pageSize), so canGoNext = false and the Next button is disabled. The gallery is left permanently empty with no mechanism to reload until the user switches tabs (unmounting and remounting GalleryView).

• Impact: Changing per-page while viewing the gallery leaves the gallery in a permanently empty, non-interactive state. No way to recover without a full tab switch.

• Minimal fix: Call pg() after resetGallery() in the effect:

  useEffect(() => {
    if (store.pageSize !== perPage) {
      store.setPageSize(perPage);
      store.resetGallery();
      pg();
    }
  }, [perPage]);

Issue 2

• Severity: medium

• Location: EncounterSearch.jsx — pg() / hasVisibleAssetsFromCursor call at line 222–226

• Problem: store.setCurrentPageItems(contents), store.setStart(), and store.setAssetOffset() are committed to the store synchronously before hasVisibleAssetsFromCursor is awaited. The Prev button in GalleryView is not gated on store.galleryLoading (only on store.currentPage <= 0), so the user can navigate backward while the look-ahead is still in-flight. When hasVisibleAssetsFromCursor eventually resolves, store.setGalleryExhausted(!hasMore) fires against the previous page's state — potentially disabling or enabling the Next button incorrectly for that page.

• Impact: After fast Prev navigation during a gallery load, the previous page's Next button can be permanently disabled (or incorrectly enabled), breaking forward pagination from a cached page.

• Minimal fix: Snapshot the current page before the look-ahead and discard the result if the page changed:

  const pageSnapshot = store.currentPage;
  const hasMore = await hasVisibleAssetsFromCursor(cumulativeStart, assetOffset);
  if (store.currentPage === pageSnapshot) {
    store.setGalleryExhausted(!hasMore);
  }
