📝 Walkthrough

Walkthrough

New client-side UI handles missing entries: reads optimistic entry from the client cache, renders a pending/indexing view, polls a blockchain edge for the real post, updates the entry cache and triggers an SSR refresh on arrival, and switches to a timed-out warning after 30 seconds.

Changes

Cohort / File(s)	Summary
Entry not-found & pending components apps/web/src/app/(dynamicPages)/entry/[category]/[author]/[permlink]/_components/entry-not-found-fallback.tsx, apps/web/src/app/(dynamicPages)/entry/[category]/[author]/[permlink]/_components/entry-pending-index-view.tsx	Adds EntryNotFoundFallback (reads optimistic cache, detects optimistic placeholder, polls blockchain with separate query key, updates main cache via EcencyEntriesCacheManagement, triggers router.refresh, 30s timeout) and EntryPendingIndexView (renders indexing UI, author/meta, progress and timeout banner).
Component barrel & page change apps/web/src/app/(dynamicPages)/entry/[category]/[author]/[permlink]/_components/index.ts, apps/web/src/app/(dynamicPages)/entry/[category]/[author]/[permlink]/page.tsx	Re-exports new fallback component; replaces previous DeletedPostScreen usage with EntryNotFoundFallback in the entry page render path.
Localization apps/web/src/features/i18n/locales/en-US.json	Adds i18n keys entry.indexing-blockchain and entry.indexing-slow for indexing status messages.

Poem

🐰 From cache-soft hope to blockchain light,
I poll and wait through day and night.
Thirty seconds — tick, then bloom,
The entry lands to end the gloom.

Docstring Coverage	⚠️ Warning	Docstring coverage is 0.00% which is insufficient. The required threshold is 80.00%.	Write docstrings for the functions missing them to satisfy the coverage threshold.

Check name	Status	Explanation
Description Check	✅ Passed	Check skipped - CodeRabbit’s high-level summary is enabled.
Title check	✅ Passed	The title partially relates to the changeset. It mentions 'optimistic post' and 'deleted posts', which align with the optimistic entry caching and deleted post handling in the new EntryNotFoundFallback component, but is somewhat vague and lacks specificity about the primary change of introducing a new fallback component.

_{✏️ Tip: You can configure your own custom pre-merge checks in the settings.}

In
`@apps/web/src/app/`(dynamicPages)/entry/[category]/[author]/[permlink]/_components/entry-not-found-fallback.tsx:
- Around line 34-39: Replace the ref-based transition gate with state: change
hasTransitioned from useRef(false) to useState(false), update handleSuccess (the
function named handleSuccess) to call setHasTransitioned(true) instead of
mutating hasTransitioned.current, and ensure the React Query option that checks
hasTransitioned for its enabled flag reads the state variable so setting it
immediately triggers a rerender and disables polling; also update the second
occurrence referenced around line 55 similarly.
