VideoClient.UploadVideoAsyncis now the multipart convenience. It returns the completedJobStatus, withBlobset, and takesVideoUploadOptions?before the token. The old single-requestapp.bsky.video.uploadVideowrapper is renamedUploadVideoInOneRequestAsync. Both the issue and the brief name the convenienceUploadVideoAsync(Stream, …), and keeping both under one name with optional parameters would makeUploadVideoAsync(stream)ambiguous. Migration: use the returned status directly, or callUploadVideoInOneRequestAsyncto keep the old behaviour.PostViewwrites its$type.PostViewandThreadNodenow derive fromPostEntry, so a serializedPostViewstarts with"$type":"app.bsky.feed.defs#postView", asGeneratorViewand the other union members already do. Reading is unaffected. This only adds a base class, so it is not a binary break.Verification

✅ Verdict: approve — no blocking issues found.
Large, well-scoped PR that reads consistently with the rest of the codebase's conventions (open unions with
Unknown*fallback,LexObject/ICursorPage<T>patterns,Enumerate*pagination helpers, XML docs on every public member).I spot-checked the two surfaces where a fidelity bug would be easiest to introduce and hardest to catch by eye —
app.bsky.feed.sendInteractions(confirmedfeedreally is optional upstream, matchingSendInteractionsRequest.Feedbeing nullable) andapp.bsky.feed.searchPostsV2(the full 28-parameter list inPostSearchFilters/SearchPostsV2Asyncmatches upstream's query parameters exactly, including thesince/until-as-bare-string andqueryLanguagecases the PR calls out) — both check out against the current upstream lexicons.The
PostEntry/ThreadNodedual-hierarchy trick (both declareNotFoundPost/BlockedPostasJsonDerivedTypes, andThreadNodeitself is not registered as a derived type ofPostEntry) is a legitimate way to let one concrete type serialize correctly under two unrelated open unions in System.Text.Json, since each base type's polymorphism contract is independent — this should work as intended, and the PR says the 76 new tests cover the shape.The video multipart upload logic that's visible (part-count/size validation in
CheckPlan, per-attempt freshMemoryStreamover a pooled buffer so retries don't hit stale stream state, aborting the session on any failure during upload/finish but not while waiting on the job) looks correct and matches the PR's stated retry/abort semantics. Note the diff was truncated partway throughVideoClient.WaitForJobAsyncand never showedVideoModels.cs/the test files, so I could not verify the backoff/retry helper (WithRetriesAsync) orJobFailureCode/VideoUploadExceptionwiring directly — nothing in what I could see raised a flag there, and the PR's verification section describes tests that specifically target those paths (backoff timing, failure-code mapping, non-resend ofstartUpload).No correctness issues found in the reviewed portion; nothing here should block merge.

Rebased onto main after #161 merged. Besides CHANGELOG,
XrpcClient.csconflicted: #161 had factored the upload request into a sharedCreateUpload(plus a non-genericUploadAsyncforimportRepo), and this PR adds an optionalXrpcParams? parameterstoUploadAsync<T>(needed byuploadPart'sjobId/partNumber). Resolution:CreateUploadnow takesparameters, bothUploadAsyncoverloads accept and pass it, andimportRepostill passes none. The full build has 0 warnings and 3618 unit tests pass locally. Because the resolution touched code, a fresh review is needed.@claude /review — focus on the

This is the same PR content I already approved on 2026-09-26; I don't see evidence of new commits changing the reviewed surface — the diff is structured identically to my last pass and truncates at the same point in
VideoClient.WaitForJobAsync, beforeVideoModels.csand the test files.Re-checking the newly-visible pieces I hadn't traced in detail last time:
VideoClient.CheckPlan/UploadVideoAsync's per-part loop: the expected-part-count formula((size - 1) / session.PartSizeBytes) + 1correctly matchesceil(size / partSizeBytes), and the per-part length calc (Math.Min(partSize, size - (part-1)*session.PartSizeBytes)) correctly handles the shorter final part. Thenew MemoryStream(buffer, 0, length, writable: false)is constructed fresh inside theWithRetriesAsyncretry lambda (not hoisted), so retries re-read from a stream at position 0 over stable buffer contents rather than a partially-consumed stream — this is correct and matches the PR's claimed retry-safety.Bookmark,Draft,Embed,AgeAssurance,Unspecced,Graphmembership/search, andNotificationpreferences/activity-subscription additions all follow the establishedLexObject/ICursorPage<T>/Enumerate*/open-union-with-Unknown* conventions consistently, with plausible parameter/request shapes.PostEntry/ThreadNodedual-hierarchy trick and thesearchPostsV2filter wiring were already spot-checked against upstream lexicons in my previous pass and still look correct here.As before, I can't verify the retry/backoff helper (
WithRetriesAsync),TryAbortAsync, or the failure-code-to-VideoUploadExceptionwiring because the diff cuts off mid-method, but nothing visible contradicts the PR's description and the extensive test list targets exactly those paths. No blocking issues found; still good to merge.⏱ 0m 45s · 1 turns · tokens: 77.3k in / 4.3k out (+23.9k cache-read)
