Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟠 High · up to This change moves recommendation generation to background jobs and client polling, but unresolved failure paths can return the wrong job, leave users stuck in a permanent loading state, or continue polling indefinitely, while the environment rename may disable AI generation in affected deployments.

Inline comments:
In @.prettierrc:
- Line 15: Update the TanStack import grouping pattern in the import-sort
configuration to match scoped specifiers beginning with `@tanstack/`, replacing
the current unscoped tanstack pattern while preserving the existing grouping
behavior.
In `@server/tasks/user-maintenance.ts`:
- Around line 21-47: The stale AI job cleanup in the user-maintenance task runs
only with the daily schedule, leaving pending or running jobs polled
indefinitely; make this cleanup execute at least every five minutes, or add a
client-side polling deadline that transitions polling to failure. Update the
flow around STALE_JOB_THRESHOLD_MS and the aiGenerationJobs update while
preserving terminal status handling.
In `@src/components/homepage-recommendations.tsx`:
- Around line 218-237: Update the startHomepageGeneration promise handler to
reset setIsGenerating(false) and isGeneratingRef.current for every outcome that
does not contain a jobId, including result.ok === false responses. Preserve the
existing error logging for error payloads and the successful jobId path.
In `@src/hooks/use-recommendations.ts`:
- Around line 197-225: Stop polling on query errors and clear the generating
state in both job pollers: in src/hooks/use-recommendations.ts lines 197-225,
update the jobQuery refetchInterval and completion effect to handle
query.state.status/jobQuery.isError by stopping polling, setting error, and
clearing activeJobId; in src/components/homepage-recommendations.tsx lines
185-195, stop refetching on errors and clear activeJobId, isGenerating, and
isGeneratingRef. Use the existing jobQuery and state-management symbols.
In `@src/lib/media-route-options.ts`:
- Around line 62-68: Update the title formatters in the media route options for
both movie and TV entries to conditionally include the separator before
titleSuffix only when the suffix is non-empty, so INDEX_HEAD with an empty
suffix produces no doubled space before “| Pebbly”.
In `@src/server/ai.ts`:
- Around line 19-21: Complete the Gemini-to-OpenRouter migration by replacing
stale GEMINI_API_KEY and callGeminiAI references in documentation and
environment templates with callOpenRouterAI and OPENROUTER_API_KEY; update
preview secret provisioning and local .dev.vars, and ensure production, preview,
and local environments provision OPENROUTER_API_KEY while leaving CI unchanged.
In `@src/server/db/schema.ts`:
- Around line 352-381: Update the existing user-maintenance task to prune
terminal aiGenerationJobs rows, deleting completed or failed jobs older than one
day using createdAt and the existing gen_jobs_status_idx-supported status
filtering. Keep pending and running jobs untouched, and reuse the established
database/task utilities rather than adding an unrelated cleanup path.
In `@src/server/env.ts`:
- Around line 44-47: Add an explicit presence check for OPENROUTER_API_KEY
before the safeParse early-return path in the environment validation flow,
ensuring the existing warning is emitted when the key is absent. Preserve the
current validation and warning-loop behavior for present keys, and reuse the
existing OPENROUTER_API_KEY warning text.
In `@src/server/fns/recommendations.ts`:
- Line 33: Break the circular dependency involving runAiJobBackground by moving
saveRecommendations, saveHomepageRecommendations, and saveHomepageFailure into a
dedicated recommendation-persistence module. Update both this server-function
module and run-ai-generation to import the helpers from that module, and remove
the direct cross-import while preserving their existing behavior.
- Around line 542-554: Scope the active-job reuse query in startGeneration to
the requested generation type, preventing homepage jobs from being returned for
recommendation requests; apply the mirrored type restriction in
startHomepageGeneration so watchlist jobs cannot satisfy homepage refreshes.
Update the queries around the existing aiGenerationJobs status checks while
preserving reuse of matching pending or running jobs.
In `@src/server/fns/watchlist.ts`:
- Around line 597-617: Update getAllWatchedEpisodes to apply an
episodeProgress.isWatched predicate through fetchEpisodeProgress, ensuring it
returns only watched rows; keep the fetchEpisodeProgress call used at the later
unfiltered path unchanged.
- Around line 609-611: Update the tmdbId condition in the episode-progress
filter to check explicitly whether options?.tmdbId is not undefined, so valid
zero values still produce the eq(episodeProgress.tmdbId, options.tmdbId)
predicate; retain undefined when no ID is provided.
In `@src/server/jobs/run-ai-generation.ts`:
- Around line 29-32: Prevent detached AI generation jobs from producing
unhandled rejections: move the initial status update into the existing try block
in runAiJobBackground so its catch path performs failure cleanup; in
src/server/fns/recommendations.ts lines 649-659 and 791-801, replace each void
bg call with void bg.catch(...) and log the error.
- Around line 35-43: Update the job timeout handling around Promise.race and
jobTimeout so the created timer is cleared whenever the race settles, including
success, failure, and timeout; follow the existing cleanup pattern in the AI
generation flow referenced by the comment.
- Around line 36-41: Remove the unused systemInstruction field from
GenerateJobParams and stop both startGeneration and startHomepageGeneration
producers from persisting it, since runAiGeneration uses the module constant
instead. Keep the runAiGeneration call and other job parameters unchanged.

@ianvs/prettier-plugin-sort-imports importOrder regex THIRD_PARTY_MODULES behavior
💡 Result:
In @ianvs/prettier-plugin-sort-imports, the <THIRD_PARTY_MODULES> keyword is a special placeholder used within the importOrder configuration array to represent all imports that do not match any of your other defined regular expression patterns [1][2]. Key behaviors include: 1. Catch-all functionality: Any import statement that is not matched by your explicit regex patterns will be automatically categorized as a third-party module [1][2]. 2. Default injection: If you omit <THIRD_PARTY_MODULES> from your importOrder configuration, the plugin will automatically inject it at the top of the import list [1][2]. 3. Controlled placement: You can explicitly place <THIRD_PARTY_MODULES> anywhere within your importOrder array to dictate exactly where these remaining imports should appear relative to your other sorted groups [3][2]. 4. Scope: It typically captures standard external dependencies installed in node_modules, but it will also capture any other import (such as root-relative paths or aliases) that has not been explicitly matched by another provided regex [1][4]. This mechanism allows you to maintain a clean import structure by defining specific patterns for your internal modules, aliases, or relative paths, while grouping all remaining external dependencies in a single location [5][6].

Align stale-job cleanup with the daily schedule.
Production runs user-maintenance once daily at 03:30 UTC. A terminated worker can leave a job in pending or running for almost 24 hours. Both clients continue polling every three seconds until the status becomes terminal. Run this cleanup at least every five minutes, or add a client-side polling deadline that reports failure.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win
An unsuccessful startHomepageGeneration response leaves the component in a permanent generating state.
The .then callback covers result.ok && "jobId" in result.data and result.ok && "error" in result.data. It does not cover result.ok === false. startHomepageGeneration runs through authedFn with feature: "ai-recommendations", which returns fail("FORBIDDEN", ...) when the feature check fails, and fail(...) for unauthorized requests.
On that path setIsGenerating(false) and isGeneratingRef.current = false never run. isGenerating stays true, so lines 458-466 render the skeleton list forever, and the ref blocks any retry for the session.
Reset the state for every non-jobId outcome.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win
Job polling ignores the query error state in both clients. Both pollers decide the interval from query.state.data?.status only. When getGenerationStatus fails (for example fail("NOT_FOUND", ...) for a missing job row, or a network outage), unwrap throws, data stays undefined, the interval stays at 3000 ms, and the active job ID is never cleared. The generating state then persists for the session and the client repeats the request every three seconds.

[warning] 218-218: This synchronous effect update causes an extra render: Calling setState synchronously within an effect can trigger cascading renders. Prefer deriving or initializing the value before render. If the effect must read a browser API after mount, treat this as advisory or suppress it with // react-doctor-disable-next-line react-hooks-js/set-state-in-effect.
Effects are intended to synchronize state between React and external systems such as manually updating the DOM, state management libraries, or other platform APIs. In general, the body of an effect should do one or both of the following:
- Update external systems with the latest state from React.
- Subscribe for updates from some external system, calling setState in a callback function when external state changes.
Calling setState synchronously within an effect body causes cascading renders that can hurt performance, and is not recommended. (https://react.dev/learn/you-might-not-need-an-effect).

Preserve the watched-only filter for getAllWatchedEpisodes.
fetchEpisodeProgress filters by user, optional tmdbId, and cursor, but it does not filter episodeProgress.isWatched. The call at Line [630-632] therefore returns unwatched progress rows from getAllWatchedEpisodes. Add a watched-only predicate for that call while keeping Line [647] unfiltered.

Use an explicit undefined check for tmdbId.
When options.tmdbId is 0, this branch omits the TMDB filter and returns all episode-progress rows for the user. The validator accepts any number, so this input is reachable. Use options?.tmdbId !== undefined.

A detached background job can reject with no handler. runAiJobBackground performs its first db.update outside the try block, so the returned promise can reject. Both start endpoints use void bg when waitUntil is unavailable, which observes no rejection. The result is an unhandled rejection, a job row stuck at pending until the reaper runs, and an unreleased rate-limit token.

Clear the job timeout timer after the race settles.
jobTimeout() creates a 2-minute setTimeout that is never cleared. When generation succeeds in less time, the timer stays pending. In a Cloudflare Worker a pending timer keeps the invocation alive, which extends the waitUntil window and the billed duration for every successful job. src/server/ai.ts lines 197-209 already documents and applies this cleanup for the same reason.

params.systemInstruction is stored but never used.
Both startGeneration and startHomepageGeneration persist systemInstruction: SYSTEM_INSTRUCTION in the job params, and GenerateJobParams declares the field as required. This call does not forward it, and runAiGeneration re-reads the module constant instead. The stored value therefore only inflates the params JSON column and creates a false impression that the instruction is pinned per job.
Either pass params.systemInstruction through runAiGeneration, or drop the field from GenerateJobParams and from both producers.
