Two follow-ups to the CatalogPurchaseWidgetView fix (6bf3366):
1. CatalogItemGridWidgetView had the same shape — four useCallback
declarations (handleDragStart / handleDragOver / handleDrop /
handleDragEnd) sat below an `if(!currentPage) return null` early
return. When currentPage flipped from null to a real page the hook
count jumped by 4 and React would have thrown "Rendered more hooks
than during the previous render" the moment any consumer rendered
the grid in admin mode. Moved the four useCallback declarations
above the early-return; their bodies are safe pre-load (only
currentPage?.offers is accessed inside handleDrop, optional-chained
already).
2. CI gate — the existing GitHub Actions workflow runs `yarn
typecheck` and `yarn test`, but NOT `yarn eslint`. That's why this
pattern slipped through twice in a row: ESLint flags it locally
but no PR check enforces it. Full `yarn eslint` emits ~900
pre-existing baseline errors (brace-style, indentation,
recommended TS rules — out of scope for this branch), so a blanket
step would always fail. Instead added a focused
`eslint.hooks.config.mjs` + `yarn lint:hooks` script that runs
ESLint with ONLY `react-hooks/rules-of-hooks: error`. Wired into
ci.yml between `typecheck` and `test`. The local repo now has
zero violations of the rule.
3. useSessionSnapshots.test.tsx — added eslint-disable-next-line
comments on the three lines that intentionally violate the rule
(they're the assertions that the broken pattern crashes). Without
the comments the new CI gate would fail on the regression-guard
suite.
Verification: yarn lint:hooks green, yarn typecheck clean, yarn test
209/209.
React reported "Rendered more hooks than during the previous render"
when CatalogPurchaseWidgetView transitioned from currentOffer=null to
a real offer: hook count jumped from 22 to 23 because the
useMemo/useEffect block for the builders-club placement state sat
*below* the `if(!currentOffer) return null` early-return on line 140.
On the first render it never ran; on the next render (offer loaded)
it did, and React's hook-call tracker flagged the divergence and
unmounted the component via the error boundary.
Fix: move the three builders-club hooks (useMemo builderPlaceableStatus,
useMemo buildersClubPlaceOneButtonStyle, useEffect interval) above the
early return. They already short-circuit cleanly when
isBuildersClubPlaceable is false — added a defensive `!currentOffer`
guard on the first useMemo and an explicit `!!currentOffer` clause on
the derived isBuildersClubPlaceable so the .product access stays safe
when offer is null. Behavior unchanged for the loaded-offer path; the
early-render path now runs the hooks but their bodies no-op.
Verification: yarn typecheck clean, yarn test 209/209.
Replaces every direct call to the deprecated useCatalog() shim with the
targeted filter(s) (useCatalogData / useCatalogUiState / useCatalogActions).
Each consumer now subscribes only to the slice it actually reads, which
restores React Compiler memoization and stops catalog-wide re-renders
whenever an unrelated key changes.
Removes the now-unused useCatalog shim from useCatalog.ts and the
shim-specific case in tests/useCatalog.filters.test.tsx. The "all four
hooks observe the same singleton" test becomes "all three filters", since
there is no shim left to compare against. useCatalogFavorites swaps its
internal useCatalog() call for useCatalogUiState() (currentType lives in
the UI slice).
Updates CLAUDE.md and docs/ARCHITECTURE.md to reflect that all 48
historical consumers are migrated and the shim is gone.
Vitest: 162/162 (was 163 — minus the deprecated-shim contract case).
Four independent components used to send 'new CatalogGroupsComposer()'
on mount and listen for GuildMembershipsMessageEvent:
- useCatalog (writing into catalogOptions.groups)
- CatalogLayoutGuildForumView
- CatalogGuildSelectorWidgetView
- WiredSelectorUsersGroupView
- WiredConditionActorIsGroupMemberView
Each fired its own request and re-listened independently. With four
of them mounted in the wired-tools panel during a builder session,
the same packet went out four times.
New useUserGroups() hook wraps the request/response pair with
useNitroQuery (queryKey ['nitro', 'user', 'groups'], staleTime
Infinity — guild membership is session-stable). All four consumers
now read 'const { data: groups = [] } = useUserGroups()' and React
Query dedups: one composer at the first mount, all subsequent mounts
get the cached array.
Drops 'groups' from ICatalogOptions and the corresponding listener +
prev-state-merge from useCatalog — no remaining consumer reads it.
React 19 dropped the no-arg useRef overload — the type-only useRef<T>()
form (no initial value) is gone, every call must pass an initial value.
The codebase had 15 occurrences of useRef<HTMLDivElement>() (DOM ref
pattern) all flagged by tsgo as 'Expected 1 arguments, but got 0'.
Mechanical sweep to useRef<HTMLDivElement>(null) — no behavior change,
React still hands out a ref object with .current set to null at mount.
Net tsgo error count: 57 -> 42.
Run eslint --fix across src/ to clear ~1900 mechanical lint errors
surfaced by the @typescript-eslint v8 + react-hooks v7 + react-compiler
upgrade in the React 19 modernization PR.
Issues fixed automatically:
- brace-style (Allman): try/catch one-liners reformatted to multi-line
- indent: tab-vs-space and depth corrections
- semi: missing trailing semicolons
- no-trailing-spaces
No semantic changes. Remaining 701 errors are real-code issues
(set-state-in-effect, rules-of-hooks, no-unsafe-* type checks) that
need manual per-file review.

- XSS fix: Created SanitizeHtml.ts utility using DOMPurify (already in package.json but never used). Wrapped all 21 dangerouslySetInnerHTML calls in catalog views with SanitizeHtml() — only allows safe tags (b, i, u, br, span, div, p, a, strong, em, img)
- Race condition fix: Added 10-second timeout fallbacks on purchase flags in CatalogPurchaseWidgetView and CatalogGiftView so the flag auto-resets even if the server never responds
- Modern card-based layout with vertical icon rail, breadcrumb nav, inline search
- Admin mode: edit/create/delete pages and offers, drag & drop reorder via HK API
- Favorites system: heart on furni, star on pages, localStorage persistence
- Redesigned product card with price pills, dynamic quantity spinner
- Upgraded trophies (filter tabs, parchment textarea), pets (breed/color flow),
custom prefix (dynamic color boxes)
- Font fix: Ubuntu Regular, proper @font-face declarations
- New Tailwind design tokens and CatalogTexts.json for localization
