fix(home): selected show lists next episodes, or latest when caught up - #1243
A selected show's episode list on Home and Daily mix's next episode for a show listened to in order now follow one set of rules (HomeShowEpisodesLogic), read from the listener's place by SeriesEpisodesLoader.
Motivation
A show whose loaded episodes were all finished showed "No episodes available", including any finished series.
In-order shows loaded only their first 100 episodes, so a listener past episode 100 got episodes 1–15 (usually finished and hidden, so again an empty list).
The place was the last episode touched, so replaying an early episode moved the list back to the start.
A failed load looked the same as a show with no episodes, with no retry.
Daily mix used a different "next episode" rule from the selected-show list, so the two could disagree.
Trailers appeared mid-series, and the NEW tag went on the two newest rows of the loaded slice rather than the show's two newest episodes.
What changed
Newest first: unfinished episodes among the newest 50 (was 25), newest at the top.
In order: the episode in progress, then the unfinished episodes after the furthest finished one; trailers skipped. A replayed early episode still leads the list while unfinished.
Caught up: with nothing left, the list shows the show's latest episodes under "You’re all caught up" and the header drops its "Next episodes" line.
Listening order: publish date, with season then episode number breaking exact-date ties (seasons released at once). Numbers never override dates.
Loading from the place: the followed show's saved copy returns episodes from the place on (PodcastRepository.getEpisodeWindow). When it can't find the place (no saved copy yet, the place stored under another ID, or a same-moment season the copy can cut), oldest-first pages are read until it turns up, keeping only that page and the next (up to 20 pages of 100). A long run of finished episodes moves loading on from the last one.
States: a failed load with nothing on screen shows "Couldn’t load episodes" with Try again (HomeViewModel.retrySelectedShow); a failed refresh keeps the list. "No episodes yet" replaces "No episodes available". "See all episodes" stays in every state.
NEW tag: only the show's two newest episodes.
Daily mix:HomeShowEpisodesLogic.nextUp replaces resolveNextSerialEpisode. A show with nothing left drops its stale suggestion and isn't resolved again until its place or newest episode changes (HomeSerialLogic.resolveKey); before, a finished series was reloaded on every history update.
Newest-first shows no longer reload the list each time another episode is played.
Behavior & compatibility
Home only; no storage, API or identity changes. Page reads stay at the existing safe limit of 100.
Daily mix no longer falls back to an earlier skipped episode once a series is finished; it matches the list's caught-up state.
"Hide completed episodes from Home show episodes" behaves as before; with it off, in-order shows keep two finished episodes before the place.
Listener impact
Tapping a show on Home never leaves an empty list once you've heard everything: you see its latest episodes and that you're caught up.
A show you listen to oldest first starts where you are, even deep into a long series, skips trailers, and Daily mix suggests the same next episode.
If a show's episodes can't load, you can try again.
Release copy
Fixed
Home's selected-show list and Daily mix share HomeShowEpisodesLogic: in-order shows list from the listener's place (in progress, else after the furthest finished episode, trailers skipped) via SeriesEpisodesLoader instead of the first 100 episodes; newest-first shows check the newest 50.
A show with nothing left lists its latest episodes as caught up instead of an empty state; a failed load offers Try again; the NEW tag only marks the show's two newest episodes.
Daily mix stops re-resolving a finished in-order show on every history update (HomeSerialLogic.resolveKey).
Test plan
Release build installed on a phone
Manual: a finished show shows its latest episodes as caught up; an in-order show partway through starts at the listener's place and Daily mix suggests the same next episode; a show opened offline shows Try again and recovers
:feature:home:testDebugUnitTest (473 tests), :feature:home:ktlintCheck and detekt pass locally
New HomeShowEpisodesLogicTest and SeriesEpisodesLoaderTest; HomeConnectedRailTest covers the failed, empty and caught-up states with Try again and See all across phone and tablet widths
Notes
Adaptive states: the list is shared by the phone column and the tablet sidebar; the new states live in the ViewModel, so they survive window resizing (covered in HomeConnectedRailTest in both directions). Foldables use the same two layouts.
A selected show's list on Home and Daily mix's next in-order episode now
share one set of rules. In-order shows read from the listener's place
instead of the first 100 episodes, continue after the furthest finished
episode and skip trailers. A show with nothing left shows its latest
episodes as caught up instead of an empty list, and a failed load offers
Try again.
Oldest-first shows now resume from the listening position, skip trailers, and keep Daily Mix suggestions in sync.
Fully listened shows display their latest episodes with a caught-up status.
Bug Fixes
Added a retry action when episode loading fails and clearer messages for shows with no episodes yet.
Home now builds selected-show episode lists from listening history, loads in-order episodes through bounded window and page lookup, and uses the same selection logic for Daily Mix. The UI receives caught-up and load-failure status, with retry and show-page actions.

Summary
Episode position and list construction feature/home/.../HomeDataModels.kt, feature/home/.../HomeSelectedPodcastLogic.kt, feature/home/.../HomeShowEpisodesLogic.kt, feature/home/.../HomeShowEpisodesLogicTest.kt
Selected-show signals use a history position for in-order shows. HomeShowEpisodesLogic orders episodes, builds selected-show rows, and selects Daily Mix next-up episodes. Tests cover ordering, completion, trailers, replay, and history position.
Bounded episode loading and selected-show state feature/home/.../SeriesEpisodesLoader.kt, feature/home/.../HomeViewModel.kt, feature/home/.../HomeViewModelSelected.kt, feature/home/.../SeriesEpisodesLoaderTest.kt, feature/home/README.md
SeriesEpisodesLoader locates a history position through a saved window or oldest-first pages. HomeViewModel loads episode pools, preserves a pool after refresh failures, and builds selected-show status. Tests cover lookup, fallback, and read failures.
Serial resolution uses the loaded history position and HomeShowEpisodesLogic.nextUp. Home records caught-up keys and skips unchanged caught-up shows.

The UI receives caught-up, load-failure, and newest-episode status. It displays a retry action after a load failure and a show-page action in the empty state. Tests cover phone and tablet layouts and the caught-up state.

Merge Risk: Low · previous review ecc71
The change looks safe to merge. Adding tests for the caught-up and retry state handling would guard against future regressions that could make the caught-up label or Try again button disappear.

Explanation
The title "fix(home): selected show lists next episodes, or latest when caught up" uses the Conventional Commits format with the allowed type "fix" and the scope "home". It matches the changeset, which changes the selected-show episode list on Home and the caught-up behavior, and it is 70 characters, under the roughly 72-character limit. The description after the colon is phrased as a third-person verb ("lists") rather than imperative mood, a minor deviation from the stated requirement.
Full details: Architecture Compliance
Explanation
The PR introduces no listed architecture violation. The changed imports stay within Home or use core modules. The PR changes no Gradle dependencies, catalog code, composition root, or storage definitions. Episode lookup uses the existing alias and projected completion APIs.

Explanation
The description is related to the changeset. It describes the selected-show episode list on Home and Daily mix next-episode selection now sharing HomeShowEpisodesLogic, loading from the listener's place via SeriesEpisodesLoader, caught-up and failed-load states with Try again, the NEW tag limited to the two newest episodes, and the related tests. It matches the raw summary's files and changes, so it is specific enough to pass.

Full details: Jvm Tests For Changed Logic
Explanation
The new selected-show ViewModel loading and recovery behavior lacks JVM tests. HomeViewModelSelected.kt now handles initial failures, preserves a pool on refresh failure, and reloads on retry. HomeConnectedRailTest supplies failure state and a retry callback directly, while HomeSelectedPodcastLogicTest checks only that the retry signal changes. Neither exercises the production recovery path. The PR does add tests for episode selection and the loader.
Resolution
Add hermetic JVM tests for the selected-show loading path. Cover an initial failure followed by a successful retry, and a failed refresh that retains the existing list.
Full details: Docstring Coverage
Explanation
Docstring coverage is 20.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 20 functions across 21 files. (3 skipped: 3 unsupported.)
Resolution
Write docstrings for the functions missing them to satisfy the coverage threshold.
