TokenComments filtered the whole list per top-level post (O(n^2) per render) and rendered every comment at once with a silent slice composer. Build the reply map once with groupReplies, paginate the top level at 20 with a Show more button and live status, persist the draft per token so a failed signature or reload never loses a typed comment, and announce the character count and errors to assistive tech.

…Twigpine#31) The draft-restore effect only assigned when a draft existed, so text typed for one token stayed in state — and was submittable — after switching to a token without a draft. Always assign the loaded value, even when empty.

The reply grouping and smaller initial render are worthwhile improvements. Please finish draft persistence so a saved reply retains its destination after a reload.
The 4 new tests and additional storage/grouping checks pass. The reply-target issue follows from the component state and stored format; I did not run a browser/wallet submission. Also, the new Show more control batches the already-fetched array. It does not consume #32's cursor, so those PRs still need coordination before calling this server pagination.

[P2] Restore the reply target along with the draft body. Start a reply to an existing comment, type text, then reload: this restores the text while replyTo initializes to null, so submitting sends parentId: null and creates a top-level post. The storage helper currently saves only text, so the original destination cannot be recovered. Persist and restore { body, parentId }, handle a missing/hidden parent explicitly, and cover restoring both a top-level draft and a reply draft.
- drafts store {body, parentId} JSON, legacy plain-text still reads
- composer restores both, persists on type/reply/cancel
- missing/hidden parent derives to top-level with explicit notice, no effect loop
- tests for top-level vs reply restore and legacy/bad parent handling

Thanks for adding the reply destination to saved drafts. That addresses the original storage issue, and blocking submission during the initial load is the right direction.
Two cases still turn a valid reply into a top-level post: a failed initial fetch, and a parent that exists outside the latest 100 returned comments. I reproduced both against this head with isolated fetch/helper checks; no browser or wallet submission was performed. The inline notes explain the fixes and regression cases.
Requesting changes until reply destinations are preserved when their validity is unknown. The response window is not authoritative evidence that a comment was deleted.

setPostsLoaded(true) also runs after an HTTP error or rejected fetch. With a restored reply and the initially empty posts array, that makes resolveReplyTarget mark the parent as missing, and submission uses parentId: null. I reproduced this with both a 503 response and a network rejection. Please mark validation complete only after a successful, valid response, keep the saved target on failure, and cover those failure cases.

@Vasanthdev2004 Thanks — fixed to only set postsLoaded=true after a successful validated response. A 503 or network rejection now keeps the restored reply pending (blocks submit) so the draft isn’t lost or silently posted as top-level. Added helper checks for both failure modes.

Not finding an ID in this array does not mean the parent is gone: the endpoint only returns the latest 100 rows. For example, a saved reply to ID 100 becomes top-level when the response contains IDs 200 through 101, even if comment 100 still exists. Please preserve the target unless its absence is checked authoritatively; if it really is unavailable, ask the user before changing the destination. Add a regression test for a valid parent outside the returned window.

@Vasanthdev2004 Thanks — you’re right the window is truncated (latest 100). Fixed resolveReplyTarget to preserve the saved parent instead of falling back to null when not found in the window, so a reply to ID 100 with window 200..101 stays as a reply. Server will reject if truly gone; no silent top-level fallback. Added regression for that case.
…runcated window (PR Twigpine#31) - Posts.tsx load(): only set postsLoaded after a successful, validated response. A 503 or network rejection no longer marks validation complete with an empty posts array, so a restored reply stays pending (blocks submit) and the draft is not silently turned into a top-level post. - post-threads.ts resolveReplyTarget(): the posts endpoint returns only the latest 100 rows, so absence in the window is not proof the parent was deleted. Preserve the saved reply target after load (no auto fallback to null); server will reject if truly gone. Adds regression for parent ID 100 with window 200..101. Verified: post-threads suite 8/8, tsc --noEmit pass, lint pass, build pass.
|
@Vasanthdev2004 Thanks for the follow-up review — both cases you reproduced are fixed: 1) Failed initial fetch (503 / network rejection) no longer loses the reply target —
2) Valid parent outside the latest-100 window is preserved —

@kevincodex1 Fixed the CodeRabbit stale-load finding (review 5194834288) and pushed commit 6403240 to perf/token-comments-ux. What was wrong: TokenComments load() had no cancellation, so a fetch for token A resolving after switching to token B overwrote B's posts/postsLoaded — wrong comments shown and reply submit unblocked early. Fix (app/src/components/launchpad/Posts.tsx:80-114): generation + AbortController guard, same pattern as PriceChart — each load() aborts the previous request, passes signal to fetch, and every state update is gated on generation/signal. Cleanup bumps generation and aborts. Verified: tsc pass, lint clean, post-threads 8/8, build pass. |

Thanks for the follow-up fixes. I checked 6403240, including the new cancellation/generation guard. The earlier draft-destination issues are addressed, and the stale-load change is useful.
One recovery issue still needs fixing before merge: a restored reply can remain stuck after the initial comments request fails, with neither Retry nor Cancel available. Details are inline. Please add a failed-load recovery path that preserves the draft and its reply destination, plus a regression test for recovery after a 503/network failure.
The eight helper tests and failure-state probes were run on 990495a during the preceding review. I checked the latest diff against that version; it changes stale-request handling but leaves this failure/recovery path unchanged. CI for the new commit was still running when I checked.

[P2] Keep a recovery action available for a failed reply-target load. With a restored reply draft, an initial 503 or network rejection leaves postsLoaded false. This branch then shows "Checking reply target...", disables submission and hides the Cancel action in the following branch. load() only retries automatically when this token appears with a new ID in the global feed, so a quiet token can stay stuck even after connectivity returns. Add an explicit failed-load state with Retry calling load(), and keep Cancel available while pending. Preserve both body and parentId when retrying; do not silently turn the reply into a top-level post.

…igpine#31) A restored reply draft plus a failed initial fetch (503/network) left the composer stuck on 'Checking reply target...' with submit disabled and no Cancel or Retry — load() only retried via the live feed, so a quiet token never recovered. - post-threads.ts: add shouldIgnoreLoad stale-guard predicate and nextPostsLoadState reducer (failure keeps postsLoaded false + arms loadError, preserving body+parentId; only ok flips loaded; ignored leaves state untouched). - Posts.tsx: load() sets loadError on HTTP/invalid/network failure via the reducer (stale/abort still ignored); composer pending branch keeps Cancel available and shows Try again on failure.

Safety check
- The change is 3 files, +446/−23. No dependency or lockfile changes, no wallet or transaction changes, and no new addresses, outside URLs, eval or HTML injection.
- Draft text is saved in the browser and only put back into the textarea, which React escapes. The saved reply target is checked to be a positive integer.
- The server still checks every reply: parent exists, same token, not hidden, one level deep (postsServer.ts:143-146). The SQL is parameterized. A tampered saved draft can't get past the server.
- All 7 commits are by Ayush7614, touching only these 3 files.
Checks, with the PR merged onto current main (including PR 29; no conflicts)
- Tests: 389 passed, 0 failed. Typecheck and lint pass.
- I didn't run the production build or a browser pass. The build fails from a scratch copy for the same reason as last time, and posting a comment needs a wallet signature.
Review status
- No one has reviewed the latest commit, 62ae84d. Vasanthdev2004's last review, on the commit before it, requested changes: a reply draft could get stuck after a failed load with no Retry or Cancel. The latest commit fixes that; I checked the code path.
- CodeRabbit hit its review limit and never ran the full review you asked for.
- CodeRabbit's last open comment asks for a test that mounts the component. I don't think it's a valid blocker: this repo tests pure helpers and has no React test setup, and the stale-response guard is covered by a helper test.
What I'd fix before merging (none of it is dangerous)
- Dead code.
- resolveReplyTarget never returns missing: true, so the "The comment you were replying to is gone" message can never show.
- initialPostsLoadState and loadDraft are only used by tests.
- The "legacy plain-text draft" branch handles a draft format that never shipped.
- nextPostsLoadState is always called with the same starting state, just to produce an error string.
- Code comments and test names reference review history ("(PR #31)").
- Accessibility regression. aria-live="polite" on the character counter makes screen readers read the remaining count on every keystroke. It should only announce near the limit.
- "Paginated" is only on screen. "Show more" reveals the up to 100 comments already fetched; nothing extra is loaded. PR 32's cursor API is now on main, but this PR doesn't use it, so comments past the newest 100 still can't be reached. This isn't a regression, and it can be a follow-up.
- Minor: clicking Reply saves the reply target even with an empty body, so a reload shows "Replying to #x" for a draft the user never typed. "Showing X of Y" also appears twice: in the button and in the status line under it.
