Pins the header row to the top of the gridWrapper scroll viewport, with
the pinned-left corner cell stacking above pinned body cells at the
top-left intersection. The trailing add-column button gets the same
sticky treatment so it doesn't drift away from the row.
Subtle bit: `position: sticky` confines an element to its containing
block. The previous subgrid `.headerRow` wrapper was 34px tall, so
sticky cells could only travel 34px before scrolling out with the
wrapper. Switching the wrapper to `display: contents` lets the cells
become direct grid children of `.grid` (full table height) so sticky
travel matches the scroll range. role="row" survives display:contents
in modern browsers.
Mounts useBaseRowsCountQuery alongside the rows query so the count is
fetched eagerly and the cache is warm by the time the toolbar consumes
it. Gating on `currentUser` (not just `base`) ensures the persisted
view-draft has hydrated from localStorage before the first count fires
— otherwise a post-refresh count races ahead of the user's saved
filter and ships without it.
Postgres has no per-expression stats for `cells->>'uuid' ILIKE '%…%'`,
`search_text ILIKE`, or `search_tsv @@`, so EXPLAIN Plan Rows falls
back to a default selectivity and is off by orders of magnitude — a
contains filter on a 10k-row base was reporting ~150 against thousands
of real matches. Auto-route any request whose filter tree contains a
contains/ncontains/startsWith/endsWith op or a search term to the
capped-exact path, even when the caller asked for an estimate.
Per-cell useResolvedPages([id]) calls each mounted with a unique
React Query key, so a grid with 20 page-typed cells fired 20 requests on
first paint. A shared loader now accumulates incoming ids within a
microtask, fires a single POST for the union, and fans the subset each
caller asked for back to them. Cells keep their own cache entry + null
handling; they just share the underlying network call.
Also renames /bases/pages/resolve → /bases/pages/expand — the old name
collided with other "resolve" semantics in the codebase.
Row-count display on a filtered view shouldn't force a full COUNT(*) on
every list fetch. New endpoint returns either an EXPLAIN-plan estimate
(default, ~1ms, no execution) or a LIMIT-capped exact count that short-
circuits to `{ capped: true }` once the match set passes EXACT_COUNT_CAP.
Clients call it in parallel with the rows query so the grid still paints
at its own pace.
- DTO + repo.countEstimate/countExact reusing the list predicate shape
- service picks the mode; controller mirrors the list Read ability check
- client hook keyed by filter/search/exact so a "show exact" toggle
doesn't clobber the estimate cache
The view-draft layer stores `{op: 'and', children: []}` as an explicit
"override baseline with no predicates" marker. That payload was leaking
into /bases/rows requests once local filter/sort drafts were enabled —
harmless server-side (buildWhere maps an empty group to TRUE) but it
destabilised the React Query key and cluttered request payloads. Normalise
empty groups to undefined at the hook level.
The withProperties subquery hydrating /bases/info was missing a
`deleted_at IS NULL` filter, so after a delete the socket-echo
invalidation refetched and the just-deleted column rehydrated on the
originating client and never dropped on others.
