feat(detail): mark a season watched from its chip on phone and TV - #299
feat(detail): mark a season watched from its chip on phone and TV#299Quick104 wants to merge 14 commits into
Conversation
Series pages only exposed "Mark Season Watched" for the selected season through the More menu on TV and had no season-level action on the phone. Long-press a season chip on either client now offers "Mark Season N as Watched" or "as Unwatched" for that chip's season, whether or not it is the selected page. The label names the season by number even when the server supplies a custom title such as "Series 2". The view models flip the chip and any loaded episode page optimistically, roll back if the server refuses, and re-read the season list and the affected episode page afterward so every checkmark and the next-up target agree. Marking a single episode now also refreshes the season flags so a chip cannot stay stale after its last episode is marked. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

When a partially watched season contains locally stored episode progress, this call records the mutation only against the season content ID, so RoomUserItemStateRepository.recordWatched does not clear the child episodes' progress rows. The success path then reloads those episodes through withLocalProgress, which restores isInProgress and the old position onto episodes the server now reports as played; TV's resolveNextUpEpisode prioritizes that stale in-progress episode and offers Resume after the whole season was marked watched. The phone implementation has the same problem, so the bulk action needs to clear or supersede local progress for every affected episode.

Confirmed and fixed in f2b815b. A confirmed season write now calls a new port method, UserItemStatePort.clearPlaybackProgress(contentIds), for the season's known episodes. The Room implementation zeroes their resume rows and drops any queued position writes so a later drain cannot reopen them. Covered by clearPlaybackProgressDropsChildResumeRowsAndQueuedPositions. Both the TV and phone view models call it.

When the watched mutation succeeds but this immediate season GET encounters a network error or 5xx, CatalogRepository.getSeasons returns the pre-mutation cached list as ApiResult.Success. This code therefore replaces the correct optimistic flag with stale data and makes the action appear not to stick; the subsequent episode reload can similarly restore cached checkmarks. The equivalent TV helper has the same behavior, so the post-write refresh must distinguish a fresh response from cache fallback or retain the optimistic values until a fresh read succeeds.

Confirmed and fixed in f2b815b. Post-write refreshes now use new CatalogRepository.refreshSeasons and refreshEpisodes, which return the network result as-is and never fall back to the pre-mutation cache. loadEpisodes gained a freshOnly flag for the same reason. Covered by refreshSeasonsDoesNotServeCacheOnServer5xx and refreshEpisodesDoesNotServeCacheOnServer5xx.

If the user reopens the menu and reverses the season state before this request finishes, both HTTP mutations remain active; the generation map suppresses stale UI handling but does not order the server writes. If the older request reaches the server last, the UI retains the newer optimistic state while the server stores the opposite value, and the ignored older completion performs no corrective refresh. The TV implementation launches mutations the same way, so requests for each season should be serialized or coalesced so the latest intent is sent last.

Confirmed and fixed in f2b815b. Season writes are now serialized per season: each new write joins the previous write's job before sending, so the latest intent is always the last request the server receives. Applied to both the TV and phone view models.

…safe Review of the season chip action found three real gaps. A partially watched season kept its episodes' local resume rows because the mutation was recorded against the season id only, so the local overlay could offer Resume on an episode the server now reports as played. The post-write season and episode reads used the cache-fallback getters, so a network error or 5xx handed back the pre-mutation list as a success and undid the optimistic state. And a quick reversal launched a second request that could reach the server before the one it reversed. Season writes for one season now join the previous write before sending. Every watched mutation bumps a shared revision and post-write refreshes publish only while that revision is still current. The refreshes use new fresh-only repository reads that never serve cache on failure. After a confirmed season write the view models clear local resume rows and any queued position writes for the season's known episodes through a new port method.

When the user long-presses an unselected season whose episode page has not been loaded in this ViewModel, previousEpisodes is null and this clears nothing; the later success path also skips refreshEpisodes because it requires previousEpisodes != null. Durable resume rows from an earlier app session therefore survive and withLocalProgress restores Resume after the server marked those episodes played.

When a TV user focuses a new season and opens the action before its slow episode load completes, onSeasonSelected has already changed selectedSeason but deliberately retains the prior season's rail as a placeholder. This condition consequently captures those old episodes as belonging to the target; when the target has no cached window page, the success path clears the unrelated season's durable resume positions while leaving the target's positions intact. Validate the episodes' season number or wait for the target page before using them.

Confirmed and fixed in 2c7f6af. The baseline captured for a season now filters the rail by seasonNumber, and the optimistic edit and rollback only touch cards whose season number matches. A placeholder rail from the previous season is never treated as the target season's episodes.

If the sync worker has already claimed an episode's SET_POSITION while the season mutation runs, this deletion cannot remove it because deletePendingForTargetKind only matches STATE_PENDING. That request can finish after the confirmed season write and reopen the episode on the server. The single-item recordWatched path handles this case by detecting an in-flight position and replaying the watched mutation; this bulk helper needs equivalent ordering or replay protection for each child.

Confirmed and fixed in 2c7f6af. The bulk helper is now recordConfirmedWatched, which routes each child through the existing single-item recordWatched path and resolves it as synced.

When the user quickly marks a season watched and then unwatched, this second invocation captures the first optimistic season as its rollback snapshot. If both serialized requests are rejected, the first completion is ignored as stale and the second restores that optimistic watched snapshot, even though neither write reached the server and the confirmed state remains unwatched. Track the last confirmed state or propagate the preceding write's outcome instead of capturing another pending intent; the TV implementation has the same failure sequence.

Confirmed and fixed in 2c7f6af. Each season keeps one confirmed baseline while writes are pending. A second write inherits the existing baseline instead of snapshotting the first write's optimistic state. A superseded write that succeeds advances the baseline to its applied state; a failure rolls back to the baseline. Applied on both the TV and phone view models.
…state Second review pass on the season chip action. Local resume rows were only cleared for episodes this screen had already loaded, so a long-press on an unvisited season left durable rows from an earlier session in place. The TV rail could still show the previous season as a placeholder during a switch, so a mark on the new season cleared the wrong episodes. The bulk clear deleted only pending position writes, so a position already claimed by the sync worker could still land after the confirmed season write. And a quick mark-then-unmark captured the first optimistic state as the second write's rollback snapshot. The port method is now recordConfirmedWatched, which routes each child through the single-item watched path: projection flips, resume rows and pending positions clear, and an in-flight position keeps a queued replay. After a confirmed season write the view models fetch the season's episode page and confirm every episode, not only the loaded ones. Episode edits and placeholder handling filter by season number. Each season keeps one confirmed baseline while writes are pending; a superseded success advances it and a failure rolls back to it. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

When a user marks a season watched and then toggles one of its episodes before the season request finishes, this cleanup records the older season value against every child. recordWatched then overwrites the episode's local projection and coalesces away its pending watched outbox operation, while the season and episode HTTP requests remain unordered; depending on response order, the server, UI, and durable local state can therefore retain different values.

Confirmed and fixed in 3781eab. recordConfirmedWatched now looks up each child's own SET_WATCHED outbox entry first and skips any child that has one, so a newer child-level intent keeps its projection and its queued write.

If the user triggers this action and leaves the detail screen before the coroutine completes, viewModelScope cancels the only code that discovers and confirms the child episodes. The season outbox operation was already persisted and can later be drained successfully, so the server still fans the mutation out, but the children's durable resume rows remain and can resurrect Resume when the episodes are loaded again; the TV implementation has the same lifecycle coupling. Fresh evidence in this revision is that the new all-episode reconciliation still runs exclusively inside the route-scoped job rather than a durable mutation/sync path.

Confirmed and fixed in 3781eab. Child confirmation moved out of the view models into a new PersonalDataRepository.setContainerWatched, which performs the write and then confirms known children plus any resolved later on a repository-owned SupervisorJob scope. Leaving the route no longer cancels it, and it is skipped if the identity generation changed. Covered by setContainerWatchedConfirmsKnownAndResolvedChildrenOnItsOwnScope, which cancels the caller scope before reconciliation runs.

When a first season write succeeds and a quickly queued reversal is rejected, the first job updates seasonWatchedBaselines to the newly confirmed state, but the second coroutine continues using the original baseline object captured here. Its failure path therefore restores the pre-first-write state even though the server accepted the first mutation; TV captures its baseline the same way. Fresh evidence in this revision is that updating the map on a superseded success does not update the already-captured baseline used by the queued write.
Useful? React with 👍 / 👎.
There was a problem hiding this comment.
Confirmed and fixed in 3781eab. After the write returns, both view models read the baseline from the per-season map (seasonWatchBaselines[seasonNumber] ?: baseline) instead of the object captured at launch, so a superseded success that advanced the baseline is what a later rejected reversal rolls back to.
Third review pass on the season chip action. Child confirmation ran on the view model scope, so leaving the screen mid-write could strand the children's durable resume rows. The bulk confirmation overwrote a child the user had toggled on its own while the season write was pending. And a serialized second write kept using the baseline it captured at launch, so a superseded success followed by a rejected reversal rolled back to the state before the confirmed write. PersonalDataRepository gains setContainerWatched, which performs the write and then confirms known children plus any resolved later on a repository-owned scope. The Room port skips a child that still carries its own pending watched intent. Both view models read the live baseline at completion instead of the captured one.

When the action targets a season whose episode page is not already loaded and the fresh episode lookup encounters a temporary network error or 5xx, resolveChildIds returns null and this coroutine exits permanently. The container write has already succeeded and its outbox operation has been resolved, so nothing retries discovery; undiscovered episodes retain durable resume rows, allowing withLocalProgress to restore Resume over episodes the server reports as played.

Confirmed and fixed in 3fcff75. Child reconciliation is now a durable RECONCILE_WATCHED_CHILDREN outbox op queued behind the season's own write.

When the detail ViewModel is cleared while setWatched is still suspended, cancellation occurs before the repository-owned reconciliation is launched. The server may already have accepted the request, or the durable season outbox may later replay successfully through SyncEngine, but neither path confirms the child episodes, leaving their resume rows intact.

Confirmed and fixed in 3fcff75. The reconciliation op is recorded in the same transaction as the season's SET_WATCHED, before any network call.

When an episode has an older pending SET_WATCHED from a transient failure and the user subsequently marks its season watched after connectivity returns, this lookup finds the older operation and skips the server-confirmed season state. The sync engine can then send that older child intent after the season fan-out and reverse the user's latest action. Fresh evidence in this revision is that getLatestByCoalesceKey is accepted regardless of creation time and recordConfirmedWatched receives no container ordering marker; compare intent age atomically and preserve only writes newer than the container action.

Confirmed and fixed in 3fcff75. content_item_state gains watchedIntentAtMs (schema v9), stamped by direct user watched actions only.

A child-level watched write landing between the intent check and the record in recordConfirmedWatched would be coalesced away by the container confirmation and then deleted by the synced resolve, losing the user's newer intent. The check, record, and resolve for each child now run in one Room transaction, and a test races a second repository's child write against the confirmation to show the child's own op survives.

When an episode mutation is pending, this page already contains that mutation's optimistic value, so the season baseline records unconfirmed child state. For example, if an unwatched episode is optimistically marked watched, the user then marks its season watched, and both requests fail with the episode failure completing first, the episode rollback restores unwatched but the later season rollback restores this watched snapshot, leaving the UI inconsistent with the server. The TV baseline captures current.episodes the same way; derive the baseline from confirmed child state or incorporate pending episode outcomes before restoring it.

Confirmed and fixed in 3fcff75. Each episode write stores its confirmed pre-optimistic value in episodeConfirmedStates for the duration of the write. Season baselines read episode state through that map, so a baseline captured while an episode write is pending holds the server value, not the optimistic one. Both clients.

When two different episodes are marked rapidly and their requests complete out of order, the newer-started request can refresh while the older request is still pending, so its response still reports an incomplete season. After the older request finally succeeds, its fresh response contains the final rollup but this global start-order revision rejects it, leaving the season chip's played flag and counts stale. TV uses the same guard; refresh ownership should follow server completion/publication order rather than invalidating every older-started successful mutation.

Confirmed and fixed in 3fcff75. Refresh ownership now follows completion order: every watched write bumps a completion counter when its request returns, and a post-write refresh publishes only if no other write completed after it began. The last write to finish therefore owns the final rollup, regardless of start order. Both clients.
The optimistic edit and its rollback on both clients wrote the same three fields in two hand-rolled blocks. One applySeasonWatchState helper per client now takes a season snapshot and publishes it, and the phone drops an unreachable fallback branch. The specials label helpers reuse isSpecialsForDisplay, which already covers season zero. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

When a profile or server switch begins after this generation check but before or during recordConfirmedWatched, the confirmation is no longer tied to the identity that accepted the container write. The Room implementation independently snapshots whichever identity is current, so it can apply the old profile's watched state to the new profile; if the switch occurs after that snapshot, it can instead recreate old-identity rows after the transition purge. Run each local confirmation through identityTransitions.withCurrentGeneration(identityGeneration) or pass the original scope into the port.

Confirmed and fixed in 3fcff75. Child confirmation moved into the sync engine, which pins every drain to the AuthScopeSnapshot captured at drain start. The catalog lookup is now scope-pinned too (CatalogApi.getEpisodes(seriesId, seasonNumber, scope)), and each child is recorded with an explicit scopeOverride for that captured identity rather than whatever identity is current.

When an episode toggle starts after the season action but completes before this reconciliation runs, resolve(SYNCED) has already deleted its outbox row, so this lookup returns null and the older container value overwrites the newer child's durable projection and resume state. The server can still retain the child value when it processed the season first, leaving local overlays permanently inconsistent. Fresh evidence after the queued-intent fix is that successful newer child intents leave no outbox row for this guard to detect; compare a retained child revision or timestamp against the container action instead.

Confirmed and fixed in 3fcff75, together with the thread above. The comparison now uses the per-row watchedIntentAtMs timestamp instead of looking for an outbox row, so a child intent that already drained is still recognised as newer than the container action.

Fourth review pass. Child confirmation still lived in a repository-owned coroutine, so it could be lost if the screen was cleared before the container write returned, if discovery failed once, or if the identity changed mid-run; and it could not tell a child's newer, already-drained intent from an older one. The view models rolled a season back over newer episode edits, built baselines from optimistic episode values, and rejected a later-completing refresh because ownership followed start order. The season write now records a RECONCILE_WATCHED_CHILDREN outbox op behind the season's own SET_WATCHED. The sync engine drains it after the container is acknowledged, confirms known episodes first, discovers the rest through a scope-pinned catalog read, and keeps the op queued with backoff when that read fails. Each child confirmation runs in one transaction and is skipped when the child's own watched intent is newer than the container action; that intent timestamp is a new column on content_item_state (schema v9) so it survives the child's outbox row. Both view models now build season baselines from confirmed episode state, leave episodes touched after the season write alone on rollback, and hand refresh ownership to the last write that completed rather than the last that started.

When the inline season request succeeds, this resolves only the SET_WATCHED handle; the separately queued RECONCILE_WATCHED_CHILDREN operation remains pending, and RoomUserItemStateRepository.resolve(SYNCED) does not request a sync unless the parent requires a position replay. With no unrelated launch, connectivity, or scope-change trigger, the child operation therefore never runs, so the immediate fresh episode response is overlaid with the old Room resume positions. Fresh evidence beyond the earlier lifecycle fix is that making reconciliation durable did not add any scheduler trigger for the ordinary success path.

When an episode watched request starts before the season action but finishes after the season fan-out, its timestamp is correctly treated as older, yet this confirmation creates a corrective child SET_WATCHED operation and immediately resolves it as SYNCED without sending it. The already-running episode request cannot be canceled by outbox coalescing and can subsequently restore the older value on the server, leaving the server inconsistent with the local season projection. Fresh evidence after the timestamp fix is that resolve(handle, SYNCED) still discards the only corrective operation instead of ordering or replaying it after the older child request.

Confirmed and fixed in 998f86d. confirmContainerChild now checks for a queued child SET_WATCHED op before recording. When one exists, meaning an older child request is still on the wire, the corrective op is left queued and a drain is requested; per-item FIFO holds it behind a claimed older op and coalescing replaces a pending one, so the season value is sent after the older request.

When the season endpoint returns a terminal 4xx, resolving the container handle deletes and rolls back only its SET_WATCHED operation; this separately keyed reconciliation remains queued. A later app launch or connectivity trigger can then run it and overwrite every child projection and clear resume progress even though the server rejected the season action. Couple this dependent operation to the parent outcome so terminal rejection removes it rather than making it eligible to drain.

Confirmed and fixed in 998f86d. A terminal rejection of a SET_WATCHED op now deletes the queued reconciliation for the same target, both in the inline resolve(TERMINAL) path and in the sync engine's terminal branch. Covered by resolvingContainerWriteTerminalDropsTheReconciliation and terminalContainerWriteDropsItsQueuedReconciliation.
The durable reconciliation op had no wake-up on the ordinary success path, survived a terminal rejection of its season write, and resolved a corrective child write locally even when that child's older request was still on the wire. Acknowledging a season write now requests a drain when a reconciliation is queued. A terminal rejection, inline or during the drain, deletes the queued reconciliation with the season op. A child confirmation leaves its corrective write queued when the child has an older write in flight, so the season value is sent after that request rather than discarded.

If the active profile or server changes after the snapshot on line 441 but before this nested call runs, recordWatched captures the new scope while the reconciliation is still enqueued with the old serverId and profileId. The API write then uses the new-scope handle, but a later drain applies its child confirmations to the old profile even though that profile never accepted the season mutation.

When an episode toggle starts after a slow season request but completes first, the server applies the newer child value and then the season request fans out its older value. This return preserves the child's local projection but leaves no outbox operation to restore that newer intent on the server, so Room and the server diverge. Fresh evidence in the final revision is that a successful newer child intent is skipped solely by timestamp; it must be replayed or otherwise ordered after the container request completes.

When a child's own intent is newer than the container action, confirmContainerChild keeps the local value and queues a non-coalescing SET_WATCHED replay of that intent, then requests a drain.

When an older episode request is still running inline, record() coalesces away its pending outbox row and leaves only the corrective operation; this immediate sync request can therefore send the correction before the older HTTP request finishes. With no remaining FIFO barrier, the older request can land last and reverse the season value on the server. Fresh evidence beyond the previous replay fix is that the correction is scheduled without waiting for the inline request represented by the deleted pending row.

Confirmed and fixed in 39bdd45. When an older child write is in flight, the corrective op is now inserted with coalesces = false, leaving the older pending row in place as the per-item FIFO barrier. dueTargetHeads will not surface the correction until that older op is resolved. Covered by confirmContainerChildQueuesCorrectiveWriteBehindAnOlderInFlightChildWrite, which asserts the older op is the only due head before its resolve and the correction is the head after.
The container write took a second identity snapshot for its own SET_WATCHED, so a scope switch mid-call could split the write from its reconciliation. A child whose newer intent had already drained kept its local value but nothing re-sent it after the season fan-out. And a corrective child write coalesced away the older pending row it needed as a FIFO barrier, so the drain could send it before the older inline request finished. recordContainerWatched now records both ops and the handle from one snapshot. confirmContainerChild queues a replay of a newer child intent instead of only skipping it, and inserts a corrective write without coalescing when an older child write is in flight, so per-item FIFO holds it behind that request.

On a TV season or episode detail route with multiple seasons, showsSeasonChips renders TvSeasonPicker, but that picker receives no watched callback, and this handler would immediately return because the detail type is not series.

When the same episode is toggled twice and the newer request finishes first, that request starts a refresh, but a later success from the older request increments lastWatchedCompletion here and invalidates it. Because the older mutation is no longer current, the else if (isCurrentMutation) branch starts no replacement refresh, leaving the TV episode rail and season rollup at the newer optimistic value even if the server applied the older request last. Fresh evidence beyond the fixed different-episode case is this same-episode generation guard; serialize these writes or let the last completion refresh even when superseded.

Confirmed and fixed in 710b4a5. A superseded episode write that still succeeded now runs the post-write refresh as well; only the current mutation clears its generation.

…eason picker Wall-clock stamps for a child action and a container action can tie, so a child toggled right after a season mark in the same millisecond was treated as stale. Watched intents now take a strictly increasing stamp, and the container action's stamp comes from the same sequence, so ties resolve by issue order. The long-press action was only wired to the series overview picker. The plain season chips shown on season and episode pages, on both TV and phone, now offer it too, and both view models derive the series id from the parent reference on those routes. A superseded episode write that still succeeded now refreshes as well; the completion ticket decides which refresh publishes, so a same-episode reversal whose older request finishes last cannot settle on a stale optimistic value.

When sign-out/sign-in or another identity transition occurs after the sync drain captures its scope but before child confirmation, this hand-built scope discards the captured identityGeneration and credential identity, and record() writes without checking the live generation. A later login that reuses the same server/profile IDs can therefore receive watched projections and replay operations from the previous identity. Fresh evidence beyond the earlier identity-change fix is that WatchedChildConfirmer passes only server/profile IDs and this line reconstructs an unstamped scope instead of preserving the drain snapshot; pass the full snapshot and gate the transaction against its generation.

When one episode write succeeds and starts refreshSeasonUserData, but another concurrent episode write fails before that GET returns, this unconditional completion bump invalidates the successful write's refresh; the failure branch performs only its local rollback and starts no replacement refresh. The season chip can therefore retain stale counts or played state despite the first server mutation succeeding. Fresh evidence beyond the prior completion-order fix is that failures now advance the ownership counter even though only successes refresh; TV has the same sequence in onSetEpisodeWatched.

On a season or episode detail route, callers correctly derive the parent seriesId, but state.detail.contentId is the season or episode ID, so this guard always rejects the refreshed season list. Consequently, marking an episode from either child route never updates the season chip's rollup from the server, and post-season-write counts remain only the optimistic approximation. Compare the route's derived parent ID instead; TvItemDetailViewModel.applySeasonUserData has the same child-route guard.

When this season-success reload is in flight and the user subsequently toggles an episode, the ownership check on the preceding line occurs only before loadEpisodes launches its asynchronous request. A response sampled before the newer episode write can still publish afterward and overwrite that episode's newer optimistic watched value; phone episode success refreshes only the season list, and withLocalProgress does not overlay locally stored watched state, so nothing corrects the stale page.

When the device clock moves backward across an app restart, lastIntentStampMs resets to zero even though watchedIntentAtMs values from the previous process remain in Room. A new season action can then receive a timestamp below an older child action; reconciliation treats that stale child intent as newer and replays it after the season fan-out, reversing the user's latest season action for that episode. Initialize the monotonic sequence from persisted state or use a durable logical revision rather than a process-local wall-clock floor.

The stamp sequence's floor is now seeded lazily from MAX(watchedIntentAtMs) in content_item_state (new DAO query), so after a restart with a clock that went backwards the first stamp is still above every persisted intent. Covered by intentStampsNeverFallBelowPersistedStampsAfterRestart.
…ownership Fifth review pass. The drain-time child confirmation rebuilt an unstamped scope from server and profile ids, so a sign-out and sign-in that reused those ids could receive the previous identity's projections. The monotonic intent stamp started from zero per process, so a clock that moved backwards across a restart could rank a new season action below an old child intent. Both view models advanced the refresh ownership counter on failed writes, matched the season-list refresh against the page's own id so season and episode routes never applied it, and let a post-write episode reload publish a page sampled before a newer episode write. The confirmer now receives the drain's full snapshot and runs under the identity barrier for that generation. The stamp floor is seeded from the highest persisted stamp. Only successful writes advance refresh ownership, the season-list refresh accepts the series parent on child routes, and the episode reload carries the refresh ticket and checks it again before publishing.

On the phone series detail, loadAllEpisodeFileIds can populate episodesBySeason[seasonNumber] while this season mutation is in flight. If the page was absent when the action began, previousEpisodesLoaded remains false, so a successful mutation skips this branch even though the map now contains a pre-mutation episode response; swiping to that nonselected season then shows stale watched checkmarks because loadEpisodes reuses the route cache without another request. Check the live cache after the write rather than the launch-time snapshot.

Confirmed and fixed in c8593a5. The phone's post-write branch now reads _uiState.value.episodesBySeason[seasonNumber] after the write returns instead of the launch-time previousEpisodesLoaded snapshot, so a page the download roll-up cached during the write is refreshed too.

When a season reversal is queued behind a slow first season write, an episode toggle made after that reversal can reach recordWatched while this job is still waiting. The reversal then records its container timestamp only after the episode, so reconciliation incorrectly classifies the later user-level episode intent as older and overwrites it with the season value; TV has the same ordering. Fresh evidence beyond the earlier timestamp-ordering fix is that the serialized job still delays creation of the container ordering marker until after previousWrite?.join().

Confirmed and fixed in c8593a5. The port exposes reserveWatchedIntentStamp(), and both view models call it at the top of the serialized job, before previousWrite?.join(). The reserved stamp is passed through setSeasonWatched to recordContainerWatched, which writes it to the season row and the reconciliation payload. An episode toggled after the action but before the season records now ranks newer. Covered by reservedContainerStampOrdersBeforeALaterChildToggle.
A season write queued behind an earlier write for the same season only took its ordering stamp after that earlier write finished, so an episode toggled in between ranked as older than the season action and was overwritten by the fan-out. The phone also decided whether to refresh a non-selected season's cached page from a snapshot taken at launch, so a page the download roll-up cached during the write was left stale. The port can now reserve a watched-intent stamp up front; both view models reserve it before joining the previous write and pass it to the season record. The phone checks the live page cache after the write. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

When a season mutation is followed by an episode toggle and both requests fail, the episode failure restores the season's optimistic value that it captured as previous, but this season rollback excludes the episode merely because it was touched later. The episode therefore remains marked with the rejected season value even though neither write reached the server; the TV path has the same outcome. Protect the child from season rollback only while its newer mutation remains pending or succeeds, not after that mutation fails.

Confirmed and fixed in 42f4a68. When an episode write fails and it is the current mutation, both view models remove the episode's entry from episodeMutationStartedAt, so a later season rollback no longer treats that episode as touched and restores it to the confirmed baseline along with the rest.

When a season write succeeds but a later episode write receives a terminal rejection before reconciliation, terminal rollback clears the row's watched value but leaves its newer watchedIntentAtMs. This branch consequently treats the rejected intent as authoritative, and the null newerValue returns without applying the accepted season state or clearing the restored resume row, so local progress can resurrect Resume over the server's watched episode. Clear or invalidate the intent stamp on terminal rollback, or distinguish rejected intents here.

Confirmed and fixed in 42f4a68. ContentItemStateDao.clearWatched, which terminal rollback uses, now also resets watchedIntentAtMs to 0, so a rejected child write no longer shields the row and the container confirmation applies normally. Covered by rejectedChildIntentDoesNotBlockContainerConfirmation, which resolves a child write as TERMINAL and asserts the later season confirmation flips the row and clears its resume position.

If a profile or server transition occurs after this drain captures its scope, confirmContainerChild declines every write through withCurrentGeneration, but WatchedChildConfirmer.confirm returns Unit, so this dispatch cannot detect the skip and still returns SYNCED; the reconciliation row is then deleted. Switching back to the original profile leaves its child projections and resume rows unreconciled permanently. Propagate whether confirmation was applied and keep the operation retryable, or otherwise preserve equivalent reconciliation work for the captured identity.

Confirmed and fixed in 42f4a68. WatchedChildConfirmer.confirm now returns whether it applied, and RoomUserItemStateRepository.confirmContainerChild returns false when withCurrentGeneration declines. dispatchReconcileWatchedChildren returns RETRIABLE on the first declined child, so the op stays queued for the captured identity's next drain. Covered by reconcileWatchedChildrenStaysQueuedWhenConfirmationIsGated.
A child write the server rejected kept its intent stamp, so the season confirmation that did succeed skipped that child and left its resume row in place. A reconciliation declined by the identity gate mid-drain was still reported as synced and deleted. And a child whose newer write failed stayed excluded from the season rollback, keeping the rejected season value. Terminal rollback now clears the intent stamp with the projection. The child confirmer reports whether it applied, and the drain keeps the op queued when it did not. Both view models forget an episode's start time when its write fails, so a season rollback can restore it. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

When another watched write succeeds while this fresh-only request is suspended, the ticket becomes stale and this return leaves isLoadingEpisodes set to true by the same load. The phone setEpisodeWatched success path refreshes only the season summary, so it neither starts a replacement episode load nor clears this flag; on a single-season series or episode detail, SeasonEpisodePage can therefore show its loading skeleton indefinitely. Clear the loading state when abandoning the request, or ensure the newer successful mutation replaces the episode reload.

Confirmed and fixed in 73c1f4e. The stale-ticket bail in the phone's loadEpisodes now sets isLoadingEpisodes = false before returning, so the page it discards cannot leave the skeleton up. TV's equivalent path already lowers episodesLoading through ownsRequest() failing before the flag is raised, so no change was needed there.

A post-write episode reload that lost refresh ownership while suspended returned without lowering the loading flag it had raised, so a single-season page could show its skeleton indefinitely. The stale page is still discarded, but the flag comes down. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

Problem
Series pages had no way to mark a whole season watched from the season selector. Android TV only offered "Mark Season Watched" for the currently selected season through the More menu, and the phone had no season-level action at all. Apple gained a long-press season menu in the matching silo-apple change, so the Android clients needed the same behaviour to stay aligned.
Solution
Long-press a season chip on the phone, or hold Select on a season tab on TV, to get "Mark Season N as Watched" or "Mark Season N as Unwatched" for that chip's season. It works for any season, not only the selected page. The label names the season by number even when the server supplies a custom title such as "Series 2".
SeasonChipsgains an optional long-press handler and aDropdownMenu.ItemDetailViewModel.setSeasonWatchedflips the chip and any loaded episode page optimistically, rolls back on failure, and re-reads the season list plus the affected episode page on success.TvSeriesModePickerseason tabs gain the existingTvMediaCardContextMenupopup with custom watched labels.TvItemDetailViewModel.onSetSeasonWatchedmirrors the phone logic and also updates the cached carousel page so neighbouring cards agree.The existing episode-card long-press menu is unchanged. The TV More menu entry for the selected season is unchanged.
