anthropicclient for the non-aipath.
src/lib/llm.tsLine 3 already exports a module-level client built fromprocess.env.ANTHROPIC_API_KEY. Line 73 constructs a second client with the same key on every static-mode request. Two consequences follow:
- Duplication: the server-key client now exists in two places. A change to the server client configuration must be applied twice.
- Failure placement:
process.env.ANTHROPIC_API_KEY!evaluates toundefinedwhen the variable is unset. The Anthropic SDK constructor then throws, and Line 73 sits outside thetryblock at Line 129.

practice_modelookup silently defaults tostaticon query failure. Both routes repeat the same settings read, discard the query error, and fall back to'static'. If the settings query fails for a user whose mode isai, the request silently takes the static path: the generate route serves asentence_banksentence, and the grade route bills the server Anthropic key. Neither route logs the failure, so the misrouting is invisible. Extract one shared helper that distinguishes "no settings row" from "query failed", and propagate the failure.

API handler to return HTTP 409 while preserving the not_enough_static_content
error code, then update the practice UI caller of /api/generate to explicitly
handle this error without reading sentence_zh, sentence_py, or vocab_used.
- Around line 49-57: Normalize and bound the parsed recent request data before
the recentIds lookup and any varietyBlock usage: retain only entries whose zh
and py fields are strings, discard null or malformed elements, and truncate both
strings to the established request-size limits. Reuse this normalized recent

Supabase filters or prompt construction.
In `@src/app/api/grade/route.ts`:
- Around line 82-99: Update the sentence lookup in the grade route so it falls
back to the other source when the current practice mode does not find the
sentence, preserving the existing sentenceRow/sentenceError handling and 404
behavior only after both lookups fail. Keep the user_id predicate on every
generated_sentences query to enforce ownership.
In `@src/lib/staticSentences.ts`:
- Around line 19-24: Update selectStaticSentence to retain and explicitly handle
the Supabase errors from the vocab_list and sentence_bank queries,
distinguishing query failures from empty results and propagating failures
instead of returning null. Preserve the settings query’s existing fallback
behavior, and update the generate route to catch the propagated error and return
a 500 response rather than not_enough_static_content.
- Around line 34-39: Update the sentence_bank query in the static sentence
selection flow to select only id, sentence_zh, sentence_py, and vocab_used,
apply recent-ID exclusion and vocab_used containment in SQL, and paginate
through all eligible rows so max_rows truncation cannot affect results. Preserve
the existing recency and accuracy-based top-five behavior, and replace the
CorpusSentence result type with a narrowed type containing only the selected
fields.

🌐 Web query:
@supabase/postgrest-js 2.105.4 .in implementation quote values filter
💡 Result:
In @supabase/postgrest-js, the.in filter method automatically manages the quoting of values to ensure compatibility with PostgREST's URL grammar [1][2][3]. When you use.in(column, values), the library performs the following logic: 1. Identification of Reserved Characters: It checks if a value contains PostgREST reserved characters (specifically commas,, parentheses (, or)), which require the value to be quoted in the generated URL [1][2][4]. 2. Automatic Quoting: If any reserved character is detected, the value is wrapped in double quotes (e.g., "value") [1][2][4]. 3. Escaping: To prevent parsing errors, the library automatically escapes double quotes (") and backslashes () that exist within these values [1][2]. It uses the backslash convention (\" for a literal double quote and \\ for a literal backslash) [2]. For example, a filter like.in("username", ["a"b,c"]) is correctly serialized to include escaped characters, ensuring the PostgREST API can parse it as a single value containing both a comma and a double quote [1][2]. Important Considerations: - Simple values that do not contain reserved characters are emitted as-is without extra quotes [1][2]. - This automatic handling is built into the.in and.notIn methods; you do not need to manually escape or quote your input values [2][3]. - If you use the lower-level.filter method (the "escape hatch"), the library does not perform this automatic quoting or escaping, and you must follow PostgREST syntax manually [5][6][3]. Top results: [1], [2], [4]

Return a non-200 status for not_enough_static_content.
This branch returns an { error } body with HTTP 200. A client that branches on res.ok treats the response as a successful generation and then reads sentence_zh, sentence_py, and vocab_used from a payload that does not contain them. The PR objectives confirm the effect: the practice UI does not handle not_enough_static_content and can crash.
Use a status the client already treats as a failure, and handle the code in the practice UI. Status 409 states that the request was valid but the corpus cannot satisfy it.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
A practice-mode change between generation and grading discards the answer.
The route reads practice_mode per request, at Line 57. It then selects the table from that value. If the user generates a sentence in one mode and changes the mode in settings before submitting the answer, the sentence_id does not exist in the newly selected table. Lines 101-103 then return 404, and the submitted answer is lost.
Resolve the sentence by identifier across both sources instead of trusting the current mode, or have the client send the source table with the grade request.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win
Do not discard the Supabase query errors.
All three queries destructure only data. If a query fails, data is null, so selectStaticSentence returns null. The generate route then returns not_enough_static_content, and the user sees a content message for a database failure. No log records the cause.
The settings lookup is a deliberate exception, because .single() errors when no settings row exists and the ?? 2 fallback covers that. Handle the vocab_list and sentence_bank errors explicitly so a failure is distinguishable from an empty result.
🛡️ Proposed fix to surface query failures
const [{ data: settings }, { data: vocab }] = await Promise.all([
supabase.from('settings').select('starting_hsk').eq('user_id', userId).single(),
supabase.from('vocab_list').select('word_zh, times_seen, times_correct').eq('user_id', userId),
])Change to capture and propagate the errors:
- const [{ data: settings }, { data: vocab }] = await Promise.all([
+ const [{ data: settings }, { data: vocab, error: vocabError }] = await Promise.all([
supabase.from('settings').select('starting_hsk').eq('user_id', userId).single(),
supabase.from('vocab_list').select('word_zh, times_seen, times_correct').eq('user_id', userId),
])
- if (!vocab || vocab.length === 0) return null
+ if (vocabError) throw new Error(`vocab_list query failed: ${vocabError.message}`)
+ if (!vocab || vocab.length === 0) return nullApply the same treatment to the sentence_bank query, and catch the error in the route so it maps to a 500 rather than to not_enough_static_content.

In `@src/lib/staticSentences.ts` around lines 19 - 24, Update selectStaticSentence
to retain and explicitly handle the Supabase errors from the vocab_list and
sentence_bank queries, distinguishing query failures from empty results and
propagating failures instead of returning null. Preserve the settings query’s
existing fallback behavior, and update the generate route to catch the
propagated error and return a 500 response rather than
not_enough_static_content.

🌐 Web query:
Supabase PostgREST max_rows response limit .not('id', 'in', '(uuid1,uuid2)') containedBy array filter documentation
💡 Result:
Supabase and PostgREST impose a default limit on the number of rows returned by an API request to prevent excessive payload sizes [1][2]. This limit (defaulting to 1,000) can be configured in your Supabase project's API settings [1]. If a query result exceeds this limit, you should use pagination with.range or provide an explicit.limit in your query [1][3]. For your specific filtering requirements, here is the syntax: Negating 'in' with.not To exclude rows where an ID is in a specific list, use the.not filter with the 'in' operator and Postgres list syntax:.not('id', 'in', '(uuid1,uuid2)') [4] ContainedBy Array Filter The.containedBy filter matches rows where every element in the column is contained by the provided value (Postgres operator <@) [5][6]. When using this with array columns in Supabase, you can pass a standard array or a Postgres-formatted string: // Using a native array.containedBy('column_name', ['value1', 'value2']) [6][7] // Using Postgres array string syntax.containedBy('column_name', '{"value1", "value2"}') [8] Note that if you require advanced filtering that the standard library does not support directly, you can use.filter as an escape hatch to pass raw PostgREST syntax [8].

Paginate and narrow the sentence_bank query.
supabase/config.toml sets max_rows = 1000, while the default seed target is 1050 rows across six HSK levels. The unbounded select('*') query can therefore truncate eligible rows before the in-memory recency and vocabulary filters run.
Select only id, sentence_zh, sentence_py, and vocab_used. Apply the recent-ID exclusion and vocab_used containment in SQL. Paginate all eligible rows, or use an equivalent query that preserves the current accuracy-based top-five selection. Return a narrowed row type instead of CorpusSentence, which declares unused fields.
