Polish pass on the proposal detail page: tabs, a wider description measure, and collapsible propdates.

What changed

1. The page is now four tabs instead of one long scroll.

Proposal / Transactions / Votes / Propdates. The header, status badges and vote summary stay pinned above the tab strip, so the at-a-glance tally never disappears. The per-section <h3> headings are gone — the tab label already names the section — and the counts that sat beside Transactions and Votes moved into the tab strip as badges.

The active tab is mirrored into ?tab=, so a tab is linkable and survives a reload. The param is removed on the default tab, keeping the canonical URL clean. Unknown values, and propdates on a chain without EAS, fall back to Proposal.

2. The description had a 65ch cap and now has a centred ~80ch measure.

Markdown applies prose from @tailwindcss/typography, which sets max-width: 65ch. On terminal-state proposals the vote sidebar is absent and the content column spans the page, so the description filled roughly 60% of its card and left a large empty gutter.

3. Propdate cards collapse.

The header (author, time, reply count) is always visible and is the toggle. The newest update starts expanded; older ones start collapsed.

Notes for reviewers

window.history.replaceState, not useSearchParams. /proposals/[id] has a dynamic segment, no generateStaticParams, and revalidate = 30; next build reports it as ƒ (Dynamic) server-rendered on demand, so its HTML is rendered per request and cached for 30s. A cached response cannot vary by query string, so the active tab has to be resolved on the client no matter how it is read. Reading window.location.search in an effect does that with no <Suspense> boundary to place, and it keeps working if this route ever becomes static — at which point useSearchParams would need a boundary whose fallback would displace the description in the prerendered HTML. The cost, identical either way: a deep link paints the default tab for one frame before the effect swaps it.

ProposalDetailView stays a server component. Panels are rendered on the server and passed to the client tab shell as ReactNode props, so the component keeps deriving everything from detail + daoConfig with no data fetching — which is what lets /dev/proposal and /proposals/[id] render identical markup.

The width fix is two elements, deliberately. max-w-none clears the typography plugin's cap and has to sit on the prose element; the wrapper carries the real measure and the centring. They can't be merged: cn's twMerge doesn't treat prose as conflicting with a max-w-* utility, so both would apply and the winner would come down to CSS source order. Markdown itself is untouched — it's shared with PropdateCard, DroposalDetail and the feed, where 65ch is right for narrow cards.

Panels mount lazily and stay mounted. An unopened tab is never mounted, so PropdateThread's 15s SWR poll doesn't run for readers who never open it. Once opened it stays mounted, so reopening doesn't refetch — but that poll then continues for the session. The Propdates tab therefore carries no count badge: the number only exists after a client fetch, and blocking the tab strip on it would delay first paint.

Tab ids are useId()-prefixed because /dev/proposal renders nine ProposalDetailView instances on one page, which would otherwise emit nine duplicate id sets and break every aria-controls relationship.

Pre-existing bug this touches but does not fix

Web3Providers (src/app/web3-providers.tsx) loads the wagmi config asynchronously and renders without QueryClientProvider until it resolves, so any useQuery in that window throws No QueryClient set. ProposalTransactionListuseDecodedTx hits this.

This is on main, not introduced here: checking out main's ProposalDetailView.tsx against a running dev server makes /proposals/1 return 500, while this branch returns 200. The tabs improve it — the transaction list is no longer rendered on first load, so the page loads — but opening the Transactions tab still trips the error boundary before recovering and rendering the list. Happy to send a separate PR hoisting QueryClientProvider above the config gate; it seemed wrong to fold an app-wide provider change into a visual polish PR.

Verification

  • pnpm test — 85/85 passing. New: src/lib/proposal-tabs.test.ts covers tab availability, ?tab= resolution, case/whitespace normalisation, and fallback for unknown or unavailable tabs.
  • pnpm lint (tsc --noEmit + eslint) — 0 errors. The 5 remaining <img> warnings are pre-existing, in files this branch doesn't touch.
  • pnpm build — passes.
  • Browser at 1600px: all four tabs render; ?tab=votes and ?tab=transactions deep-link correctly; the description shows a centred ~80ch measure with balanced gutters; ARIA verified from the served HTML (one role="tablist", four role="tab" with correct aria-selected/aria-controls, roving tabIndex, no duplicate ids); lazy mounting confirmed — only the active panel is in the served DOM.

Not verified: the propdate collapse interaction was only exercised through code review — the DAO I tested against has zero propdates, so the collapsed/expanded states had nothing to render. Keyboard navigation (Arrow/Home/End) was confirmed from the DOM and by reading the handler, not by an actual key pass. The repo's vitest runs environment: 'node' with no jsdom, so component-level tests weren't an option; unit tests cover the pure tab model instead.

React StrictMode double-invokes state updater functions in dev; the
previous toggle() called onReplyClick(propdate) inside the setExpanded
updater, which is a side effect on another component's state. Read
`expanded` from the closure instead and fire the side effect before
calling setExpanded, so it runs exactly once per click.

(cherry picked from commit 57e33f00b5b20b8351e142a0f4b0081056e05315)
- Derive tab/panel DOM ids from useId() instead of hardcoded strings,
  so multiple ProposalTabs instances on one page (e.g. the dev proposal
  state matrix) don't collide on aria-controls/aria-labelledby.
- Mark a tab as mounted in the same state update as making it active
  (via a shared `activate` helper) instead of a separate effect, which
  removed a one-frame empty-panel glitch on first activation.
- Note in the doc comment that the Propdates SWR poll keeps running for
  the rest of the session once that tab has been opened.

The proposal detail view now uses URL-aware tabs for its content panels. Propdate cards support expandable bodies, reply counts, accessible toggles, reply cancellation on collapse, and first-card expansion.

Expandable propdate cards

Adds collapsible card bodies, reply counts, accessible controls, reply cancellation on collapse, and default expansion for the first card.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🔵 Low · up to fc31c

The proposal page changes are mergeable with owner awareness that opening Transactions during wallet configuration loading may briefly fail before recovering; a follow-up provider fix should address that bounded interaction risk.

Drop tabIndex={0} on panels that contain focusable content.

The panels render buttons and links, for example ProposalVotesList filter chips and PropdateThread controls. The ARIA authoring practices add tabindex="0" to a tabpanel only when the panel holds no focusable element. Here it adds one extra tab stop per opened panel with no benefit.

Consider pushState for tab changes so Back returns to the previous tab.

selectTab uses window.history.replaceState, so tab changes create no history entry. Two consequences follow:

  • Back leaves the proposal page instead of restoring the previously viewed tab.
  • The popstate listener registered at Line 68 cannot fire for tab changes, because no entry is ever pushed.

If you want Back to restore the previous tab, use pushState for user-initiated tab changes and keep replaceState only for the initial normalization. If the current behavior is intentional, state that in the doc comment so the popstate listener is not read as tab history support.

Wrap mounted panels in <Activity mode={key === active ? 'visible' : 'hidden'}>.

React 19.2.5 supports this API. Hidden mode preserves state and DOM while cleaning up effects, so the PropdateThread 15s SWR poll stops while hidden and resumes when visible.
