feat(frontend): automated invoice matching engine for lender-invoice fit - #233
Conversation
Implements the full lender-invoice matching engine described in Stellar-VaultLink#230. ## What's added ### Core algorithm — lib/matching.ts Weighted scoring engine with five factors per invoice: - risk (invoice amount + duration + profile) - currency alignment - estimated yield vs. lender minimum - originator historical repayment record - due-date horizon fit Weight matrices vary per risk profile (conservative / moderate / aggressive) so aggressive lenders are rewarded for risk and conservative lenders penalise it. Hard amount filters run before scoring for performance. ### Types — src/types/matching.ts LenderPreferences, MatchResult, ScoreBreakdown, MatchQuality, serialisation helpers (bigint-safe for localStorage). Re-exported from the types barrel. ### Hooks - useLenderPreferences — two-tier persistence: localStorage (always) + Supabase lender_preferences table (when authenticated). Explicit save() avoids unintended network round-trips. - useMatchedInvoices — TanStack Query for raw data, useMemo for scoring so re-renders do not re-fetch. ### Components - LenderPreferencesForm — shadcn Dialog + react-hook-form + Zod. Segmented OptionButton controls for risk profile and currency, numeric inputs for yield / amount bounds / due-date horizon. - MatchQualityBadge — four tiers (excellent / good / fair / poor) with colour coding. - SuggestedMatches — responsive grid of matched invoice cards, each with a hover/focus score breakdown panel showing per-factor bars, loading skeletons, empty state, and a 'Browse all' override button. ### Marketplace integration — src/app/marketplace/page.tsx - 'Suggested for me' view (default) shows AI-ranked matches. - 'Browse all' view preserves original filter/sort/search behaviour. - Preferences button in page header. - Scoped QueryClientProvider so the page adopts TanStack Query incrementally. ### Supabase migration src/lib/migrations/001_lender_preferences.sql — lender_preferences table with RLS, unique index per lender, and updated_at trigger. ### Tests — src/lib/__tests__/matching.test.ts 30 unit tests covering all score components, quality tier boundaries, composite score bounds [0, 100], hard filters, limit, sort order, and the performance acceptance criterion (<100 ms for 1 000 invoices — runs in ~1 ms). Added @invofi/sdk alias to vitest.config.ts so tests resolve the SDK types. Closes Stellar-VaultLink#230

Inline comments:
In `@invofi/apps/frontend/src/app/marketplace/page.tsx`:
- Around line 173-191: Add accessible names to the status and currency select
controls in the marketplace page, using descriptive aria-label values consistent
with the existing sort select. Keep their current filter values and change
handlers unchanged.
- Around line 68-71: Debounce the search value used by useMarketplace while
keeping the raw search state bound to the input onChange. Add the necessary
React hook and update the query configuration to use the debounced value,
preserving the existing empty-search behavior.
- Around line 84-85: Update the amount sorting cases in the marketplace sort
comparator to compare Invoice.amount values as bigint, avoiding Number
conversion and precision loss. Return a fixed negative, zero, or positive sign
for amount_desc and amount_asc while preserving their existing sort directions.
- Around line 204-215: Update the browse-all rendering around allInvoicesQuery
and sortedAll so the empty-filter message is suppressed when
allInvoicesQuery.isError is true, and handle the failed-query state before the
empty state with the existing error/retry behavior used by the suggested view.
Ensure the invoice grid is also guarded against rendering during an error.
- Around line 19-24: Remove the page-level QueryClient creation in the
marketplace page and use the existing root QueryClientProvider from Providers
for its TanStack Query hooks. Ensure the page does not instantiate or mount a
separate client, preserving the root client’s cache and defaults.
In `@invofi/apps/frontend/src/components/marketplace/LenderPreferencesForm.tsx`:
- Around line 37-39: Export shared RISK_PROFILES and CURRENCY_PREFERENCES tuples
from matching.ts, derive RiskProfile and CurrencyPreference from them while
keeping CurrencyPreference aligned with Currency, and import those tuples into
LenderPreferencesForm. Build the Zod enum schema and both option lists from the
shared tuples, removing all duplicated literal arrays.
- Around line 65-85: Fix the precision loss in prefsToForm and formToPrefs:
avoid converting stroop amounts through Number or floating-point multiplication,
and use decimal-string conversion that preserves exact stroop values across the
full allowed amount range. Keep the existing XLM/stroop scaling and rounding
behavior for form inputs, and verify the conversion uses the integer
STROOPS_PER_XLM constant.
In `@invofi/apps/frontend/src/components/marketplace/MatchQualityBadge.tsx`:
- Around line 43-61: Update MatchQualityBadge’s Badge accessibility attributes
so its aria-label always includes the match quality and score, including compact
mode, instead of relying on title; mark the decorative glyphs in the quality
labels as aria-hidden so screen readers announce only the meaningful label text.
In `@invofi/apps/frontend/src/components/marketplace/SuggestedMatches.tsx`:
- Around line 259-265: Update the isError branch in SuggestedMatches so it
retains a browse-all escape hatch, either by rendering the onBrowseAll control
there or by keeping the section header and placing the error message within the
section body. Ensure lenders can invoke onBrowseAll when matching fails.
- Around line 42-69: Move the DueLabel component into a shared module, then
import and reuse it from both SuggestedMatches and MarketplaceCard. Remove the
local duplicate from SuggestedMatches while preserving the existing due-date
thresholds, wording, styling, and formatDate behavior.
- Line 166: Update the trigger button styling in SuggestedMatches to preserve a
visible keyboard focus indicator: replace the outline suppression with the
established focus-visible ring utilities used by OptionButton, including
focus-visible:ring-2 and focus-visible:ring-ring.
- Around line 158-173: Update the score breakdown trigger around the Info button
to support click toggling for touch devices and expose accessible state with
aria-expanded and aria-controls tied to the rendered ScoreBreakdownPanel.
Preserve hover and focus behavior without letting onBlur immediately undo a
click toggle, and add Escape-to-close behavior (prefer the existing Popover
primitive if it provides these interactions).
- Around line 246-247: Remove the unused allInvoices property from
SuggestedMatchesProps and remove the Invoice import if it is no longer
referenced elsewhere in SuggestedMatches.tsx.
- Around line 143-152: Update the Stellar Expert link in MatchedInvoiceCard to
use the account path for invoice.originator, changing the URL target to
/account/${invoice.originator}; remove the unnecessary onClick propagation
handler while preserving the existing target, rel, title, and styling.
In `@invofi/apps/frontend/src/hooks/useLenderPreferences.ts`:
- Around line 158-166: The save path around the upsert in
invofi/apps/frontend/src/hooks/useLenderPreferences.ts:158-166 must no longer
swallow Supabase failures: re-throw the error so LenderPreferencesForm.onSubmit
does not treat the submission as successful, or expose the hook error through
LenderPreferencesFormProps and render it. In the delete path at
invofi/apps/frontend/src/hooks/useLenderPreferences.ts:177-190, replace the
empty catch with error-state handling so failed deletes are surfaced and
hydrate() cannot silently restore stale preferences.
- Around line 96-107: In useLenderPreferences, track local changes with a useRef
flag and set it at the start of both save and reset; in hydrate, apply the
remote data to storage and state only when the component is not cancelled and no
local write has occurred. Preserve the existing hydration behavior when no local
save or reset happens first.
In `@invofi/apps/frontend/src/hooks/useMatchedInvoices.ts`:
- Around line 49-52: Update fetchOriginatorHistory around the row.invoices
extraction to handle both object and array relationship shapes, selecting the
invoice object before reading originator and skipping rows without one. Remove
the incompatible object-only cast and confirm the financing_offers-to-invoices
relationship cardinality using the existing schema or generated Supabase types,
preserving extraction for whichever runtime shape is returned.
- Around line 27-36: Update fetchPendingInvoices to select only the Invoice
fields required by matching and invoice cards, then apply an explicit limit
using the shared MAX_MATCH_CANDIDATES constant from `@/lib/constants`. Ensure the
selected columns remain compatible with the Invoice type and preserve the
existing pending-status and newest-first ordering.
In `@invofi/apps/frontend/src/lib/__tests__/matching.test.ts`:
- Around line 6-8: Update the test header comment to acknowledge its use of the
Next.js `@/` alias, remove the locally defined STROOPS_PER_XLM, and import the
shared constant from the same constants module used by matching.ts so fixture
values stay synchronized with production.
- Line 19: Update the matching test coverage by adding an assertion that each
profile’s WEIGHT_MATRIX row sums to 1.0; export WEIGHT_MATRIX if needed for
direct testing, or verify the invariant indirectly with an all-100 sub-score
invoice producing a score of 100 for every profile. Keep the documented coverage
list aligned with the implemented assertion.
- Around line 276-291: Make the 1,000-invoice fixture in the performance test
deterministic by replacing both Math.random() calls with index-derived amount
and due-date values while preserving the existing value ranges and distribution
shape. Keep the matchInvoices invocation and performance assertion unchanged.
In `@invofi/apps/frontend/src/lib/matching.ts`:
- Around line 75-82: Update the risk calculation around rawRisk so aggressive
profiles invert only the amount component, while durationRisk remains in its
original direction. Adjust the aggressive branch near the riskProfile check to
combine the mirrored amount score with the unchanged duration contribution,
preserving overdue as the worst duration tier.
- Around line 285-290: Normalize each invoice’s amount with toStroopsBigInt
while constructing the results in fetchPendingInvoices, before the invoices
reach the matching loop and scoreInvoice. Replace the raw human-unit decimal
string with the resulting stroops bigint, preserving the remaining Invoice
fields and existing filtering/scoring behavior.
- Around line 156-173: Update the history scoring logic around repayRate in
fetchOriginatorHistory’s caller to use repaidOffers plus defaultedOffers as the
denominator, returning 50 when no offers have settled. Remove the unused
defaultRate variable and preserve the existing penalty, volume bonuses, and
score clamping.
Apply the same fix in `@invofi/apps/frontend/src/hooks/useMatchedInvoices.ts`
around lines 39 - 44: The same settled-versus-outstanding denominator issue is
reflected in the hook's history aggregation.
In `@invofi/apps/frontend/src/lib/migrations/001_lender_preferences.sql`:
- Around line 58-60: Make the lender_preferences_updated_at trigger creation
idempotent by dropping that trigger on lender_preferences immediately before the
existing CREATE TRIGGER statement. Keep the trigger definition and
update_updated_at_column function unchanged.
- Around line 25-26: Add digit-only CHECK constraints to the max_amount_stroops
and min_amount_stroops columns in the lender preferences migration, ensuring
stored text is valid for BigInt parsing while preserving their existing NOT NULL
and default behavior.
- Around line 43-47: Update the “Lender can manage own preferences” policy on
lender_preferences to target only the authenticated role and use scalar
subqueries for each auth.uid() comparison in both USING and WITH CHECK,
preserving the existing ownership condition.
- Around line 50-56: Replace the generic update_updated_at_column trigger
function with public.lender_preferences_set_updated_at(), configure it with SET
search_path = '', and update the lender preferences trigger to invoke this
schema-qualified function.
In `@invofi/apps/frontend/src/types/matching.ts`:
- Around line 141-150: Update deserializePreferences in
invofi/apps/frontend/src/types/matching.ts at lines 141-150 to validate every
serialized preference field and use the corresponding DEFAULT_PREFERENCES value
when malformed, including safe BigInt conversion. In
invofi/apps/frontend/src/hooks/useLenderPreferences.ts at lines 97-104, coerce
max_amount_stroops and min_amount_stroops to strings instead of asserting the
Supabase row shape, and verify the corresponding column types and nullability in
001_lender_preferences.sql.

TanStack Query v5 Next.js App Router QueryClient module scope server sharing
💡 Result:
In TanStack Query v5 with the Next.js App Router, using a module-scope QueryClient (a singleton defined at the top level of a module) is strongly discouraged and actively harmful [1]. Because the Next.js server is long-lived, a module-scope client persists across requests, which will lead to data leaking between different users and requests [2][3][1]. The recommended architecture involves two distinct approaches for server and client environments: 1. Server-Side (Per-Request): You must instantiate a fresh QueryClient for every incoming request [3][1]. This is typically implemented using a factory function (e.g., getQueryClient) [4][3][5]. When a Server Component needs to fetch data, it calls this factory to get a request-specific client, performs prefetching, and then passes the dehydrated state to a HydrationBoundary [4][3][5]. 2. Client-Side (Singleton per Session): On the client, you must ensure the QueryClient is instantiated once per browser session [1]. This is usually achieved by creating the client inside a Client Component (typically a provider) using React.useState or a ref, ensuring it is recreated only if the component lifecycle requires it, but stable across the application's life in the browser [2][1]. To implement this pattern: - Define a getQueryClient helper that creates a new QueryClient on the server and retrieves/initializes a singleton on the client [3][5]. - In Server Components, call getQueryClient, perform prefetching with prefetchQuery, and provide the cache to the client-side via a HydrationBoundary [4][3][5]. - Wrap your application in a Client Component provider (e.g., Providers.tsx) that holds the QueryClient instance in state, ensuring the client is stable for the duration of the user's session [2][1]. This approach ensures that the server correctly isolates data for every request while the client maintains a single cache that hydrates seamlessly from the serialized server data [2][3].

site:tanstack.com/query/latest/docs/framework/react Next.js App Router QueryClient useState client provider module scope server request
💡 Result:
In Next.js App Router applications, you must ensure that each server request gets its own QueryClient instance to prevent cross-request data leaking [1][2]. Creating a QueryClient at the module scope (outside of components) is unsafe because it creates a singleton shared across all users and requests [1][2]. To implement this correctly in the App Router: 1. Create a singleton getter function: Define a helper function (e.g., getQueryClient.ts) that uses React's cache function (from react) to ensure the QueryClient instance is memoized for the duration of a single server request. // lib/get-query-client.ts import { QueryClient } from '@tanstack/react-query'; import { cache } from 'react'; const getQueryClient = cache( => new QueryClient); export default getQueryClient; 2. Use a Client Component for the provider: Create a Providers component marked with 'use client' to wrap your application, as QueryClientProvider relies on React Context [3]. // app/providers.tsx 'use client'; import { QueryClientProvider } from '@tanstack/react-query'; import getQueryClient from '@/lib/get-query-client'; export default function Providers({ children }) { const queryClient = getQueryClient; return ( {children} ); } When using the App Router, avoid initializing the client with useState inside the provider component if you are using Server Components for prefetching, as this can lead to issues with React Suspense boundaries [3]. Instead, use the memoized getter function pattern to manage the instance correctly [3]. This ensures that the server creates a fresh client for every request while the client-side remains consistent [3].

site:nextjs.org/docs app router client components prerendered server use client module scope
💡 Result:
In the Next.js App Router, Client Components are indeed prerendered on the server during the initial page load to provide an immediate, non-interactive HTML preview [1][2][3]. This allows users to see the page content before the JavaScript bundle is fully downloaded, parsed, and executed [1][3]. Key aspects of this process include: 1. Server-Side Prerendering: During the initial request, Next.js renders both Server and Client Components into HTML on the server [1][3]. For Client Components, this HTML is a static representation; full interactivity is only enabled once the client-side JavaScript is hydrated [1][3]. 2. The "use client" Module Scope: The "use client" directive marks a boundary between the server and client module graphs [4][5]. When a file is marked with "use client", it and all modules it imports (including child components) are included in the client-side JavaScript bundle [4][1][2]. Because of this, you do not need to repeat the directive in every component; the boundary propagates to all dependencies imported into that module [4][5]. 3. Prerendering and Hooks: When prerendering routes—especially with features like Partial Prerendering (PPR)—navigation hooks that rely on runtime request data (such as useSearchParams, useParams, or usePathname) may not have access to their values [6][7]. If these hooks are called outside of a Suspense boundary, it can cause prerendering errors [6][7]. To resolve this, these components should be wrapped in a Suspense boundary, allowing the server to render a fallback and stream the dynamic component later once the runtime data is available [8][6][7]. 4. Subsequent Navigations: After the initial page load, Client Components are rendered entirely on the client, and the server does not send additional HTML for them [1]. Instead, the React Server Component (RSC) Payload is used to reconcile the component tree and update the DOM [1][3].

TanStack Query v5 useQuery server rendering queryFn executes during Next.js App Router client component prerender no suspense
💡 Result:
In the Next.js App Router, TanStack Query v5's useQuery hook does not execute its queryFn during the server-side prerender or initial server-side rendering (SSR) process [1]. By default, useQuery is designed to execute only on the client side [1]. If a Client Component containing a useQuery hook is prerendered on the server, the queryFn will not run, and the hook will not initiate a data fetch [1]. This behavior persists even if you wrap the component in a Suspense boundary; while Suspense will handle loading states, the actual data fetching triggered by useQuery will only begin once the component mounts in the browser [1]. To achieve server-side rendering and avoid a "loading" state during initial page load, you must use the standard hydration pattern [2][3][4]: 1. Prefetching: Use queryClient.prefetchQuery within a Server Component to fetch the data on the server [2][3]. 2. Dehydration: Wrap your client components in a HydrationBoundary component and pass the dehydrated state from your queryClient [2][5][6]. 3. Rehydration: On the client, when the page loads, useQuery will detect the prefetched data in the cache and provide it immediately, bypassing the need for a client-side fetch [3][4][6]. If you omit the prefetch step, your client-side useQuery hook will simply remain idle during the server render and will trigger the fetch only after the component reaches the client [1]. Note: If you use the newer useSuspenseQuery hook in a Client Component, it is still subject to the same requirement—it will not trigger server-side fetching unless that data has been explicitly prefetched on the server and passed down via HydrationBoundary [2][7]. Without prefetching, useSuspenseQuery will simply suspend the component on the client after the initial HTML has been rendered [1][8]. Additionally, be aware that calling dehydrate during certain prerendering phases (such as with Cache Components in newer Next.js versions) can sometimes trigger errors related to reading the current time if not handled correctly; ensure you are following the latest official TanStack Query documentation for hydration patterns [9].

site:tanstack.com/query/v5/docs/framework/react/guides/advanced-ssr useQuery Server Components queryFn server
💡 Result:
In TanStack Query, you cannot use the useQuery hook directly within React Server Components because hooks are only supported in Client Components [1]. Instead, to leverage TanStack Query with Server Components, you should perform the following pattern: 1. Prefetching on the Server: In your Server Component, create a QueryClient, use await queryClient.prefetchQuery to fetch your data, and then dehydrate the state [1]. 2. Hydration: Wrap your component tree in a HydrationBoundary (a Client Component) and pass the dehydrated state to it [1]. 3. Client-Side Access: In your Client Components (children of the HydrationBoundary), use the standard useQuery hook. Because the data has already been prefetched and dehydrated, useQuery will immediately use that cached data without triggering a redundant network request [1]. Regarding queryFn and Server Actions: Do not use Server Actions as the queryFn for fetching data in useQuery [1]. Server Actions run serially when called from the client, which can cause performance bottlenecks or issues with React Query's parallel fetching and refetching logic [1]. Additionally, passing Server Actions as references can lead to serialization errors [1]. Server Actions should be used for mutations (via useMutation), while data fetching should rely on standard fetch requests, API routes, or RPC libraries [1].

Use the root QueryClientProvider instead of creating a page-level client. The root Providers component already owns a state-stable QueryClient. The page-level provider creates a separate cache and bypasses the root query defaults. These page queries do not prefetch or execute on the server, so this is not a cross-request data-leak issue.

The search input triggers one request per keystroke.
Line 70 passes search directly into useMarketplace. Line 170 updates search on every onChange. Each character therefore produces a new query key and a new fetch. Typing a 20-character originator address issues 20 requests, and the responses can resolve out of order.
Debounce the value that feeds the query, and keep the raw value for the input.

Compare amounts as bigint in the sort comparator.
Invoice.amount is a bigint of stroops. Lines 84 and 85 convert both operands with Number. Above 2^53 stroops the conversion rounds, two distinct amounts can map to the same double, and the comparator then reports a tie. Compare the bigint values and return a fixed sign.

A failed query renders as "No invoices match your filters".
The browse-all view branches on allInvoicesQuery.isLoading only. If the query fails, isLoading is false and sortedAll is empty, so line 210 shows the empty-filter message. The user reads a fetch failure as a valid empty result and has no retry path. The suggested view already receives isError on line 153, so the two views report failures inconsistently.

Supabase database linter function_search_path_mutable recommendation
💡 Result:
The Supabase database linter warning "function_search_path_mutable" (rule 0011) identifies database functions that lack an explicit, pinned search_path configuration [1][2]. Why it matters In PostgreSQL, the search_path determines the schema lookup order for unqualified object names (like tables, functions, or operators) [3][2]. If a function does not have a pinned search_path, it inherits the search path of the session that calls it [3][4]. For SECURITY DEFINER functions—which execute with the privileges of the function's owner—this creates a critical security vulnerability: a malicious user could manipulate their own session's search_path to inject a fake object (e.g., a table or operator with the same name) into the search order, causing the elevated function to execute that malicious object instead of the intended one [3][1][4]. How to resolve To resolve this warning, you must explicitly set the search_path for the function [3][2]. 1. Pin the search path: The recommended best practice is to set the search_path to an empty string ('') [3][2]. This forces you to use fully qualified names (e.g., public.profiles instead of profiles) for all objects within the function, which is the safest approach because it eliminates reliance on search order entirely [3][2]. Example: sql create or replace function example_function() returns void language sql set search_path = '' as $$ select * from public.my_table; $$; 2. Alternatives: While pinning to an empty string is the standard recommendation, any explicit, non-empty search_path (e.g., set search_path = public) will also satisfy the linter and secure the function against session-based path manipulation [5]. If you use specialized operators (like those from pgvector), you may need to include the schema where those operators reside (e.g., set search_path = public, extensions) or explicitly qualify the operator using OPERATOR(schema.operator_name) [6]. Important Note: Fixing the search_path is mandatory for SECURITY DEFINER functions [4]. While applying it to SECURITY INVOKER functions is also considered a good habit for consistent behavior, the risk of privilege escalation is directly tied to SECURITY DEFINER [4]. Always ensure your function body is updated to use fully qualified object references once the search path is pinned [3][4].

site:postgresql.org/docs CREATE FUNCTION search_path schema qualification trigger execute function
💡 Result:
In PostgreSQL, managing the search_path is critical for security, particularly when creating functions—including trigger functions—that are defined as SECURITY DEFINER [1][2]. The search_path determines the order in which schemas are searched when database objects (such as tables, functions, or operators) are referenced by an unqualified name [3][4]. If a function is defined as SECURITY DEFINER, it executes with the privileges of the user who owns it [1]. If the search_path is not explicitly set, a malicious user who has CREATE privileges on a schema within the search path could create objects (e.g., a table with the same name as one the function expects to access) to subvert the function's behavior [1][3]. Best Practices for Functions and Trigger Functions: 1. Set a Secure search_path: When using SECURITY DEFINER, always include a SET clause to define a secure, trusted search_path [1]. This ensures the function does not inadvertently reference untrusted objects [2][3]. Example: CREATE FUNCTION my_trigger_func RETURNS TRIGGER AS $$ BEGIN... END; $$ LANGUAGE plpgsql SECURITY DEFINER SET search_path = admin, pg_temp; 2. Use Qualified Names: Even with a secure search_path, explicitly using schema-qualified names (e.g., schema.table_name) within your function code is a robust way to ensure that the function always references the intended object, regardless of the search_path [3][5]. 3. Managing search_path for Existing Functions: If you have already created a function, you can adjust its search_path behavior using the ALTER FUNCTION command [6]. Example: ALTER FUNCTION my_trigger_func SET search_path = admin, pg_temp; To revert to the caller's search_path (not recommended for SECURITY DEFINER functions), use: ALTER FUNCTION my_trigger_func RESET search_path; Trigger Functions Specifics: Trigger functions are created using the standard CREATE FUNCTION command [7][8]. They do not require special handling for schema qualification compared to other functions; however, they often rely on special variables like TG_TABLE_SCHEMA to identify the context in which they are running [7]. Security considerations apply equally to trigger functions, especially if they perform sensitive operations or access objects outside the schema where the triggering table resides [2].

💡 Result:
The term function_search_path_mutable refers to a linting rule, primarily used by the Supabase database advisor and CLI tools, which warns when a PostgreSQL function does not have a fixed, explicit search_path [1][2]. In PostgreSQL, the search_path setting determines the order in which schemas are searched to resolve unqualified object names (such as tables or functions) [1][3]. If a function does not have a pinned search_path, it inherits the search_path of the user executing the function [1][2]. This behavior creates two primary risks: 1. Inconsistency: The function may behave unpredictably or produce different results depending on the calling user's environment [1][2]. 2. Security Vulnerability: If the function is defined with security definer (executing with the creator's privileges), a malicious user could exploit a mutable search_path to trick the function into referencing unintended objects (e.g., a malicious table or function) that the caller controls [1][2][3]. To resolve this issue, best practice dictates that you should explicitly set the search_path for your functions, particularly when using security definer [4][3]. Pinning the search_path to an empty string (set search_path = '') is the recommended approach, as it forces all references within the function body to be fully qualified with their schema (e.g., public.mytable) [1][2][3]. Example implementation: create or replace function example_function returns void language sql set search_path = '' as $$ select count(*) from public.mytable; $$;

Define public.lender_preferences_set_updated_at() with SET search_path = '', then update the trigger to call the renamed function. The current generic, unqualified name can collide with another same-signature function, and Supabase reports function_search_path_mutable for the unset path.

Preference values cross a trust boundary with no validation before BigInt() conversion. localStorage JSON and Supabase rows are both asserted into LenderPreferencesSerialized and passed straight to deserializePreferences, where BigInt() throws on a non-numeric string or undefined.

Supabase infers a joined one-to-many relation as an array even when the FK guarantees a single row. Cast rawInv as both shapes and normalise with Array.isArray before use, fixing the TS type-check failure on line 51.

Summary
Implements the full automated invoice-lender matching engine described in #230. Lenders get a ranked "Suggested for me" view in the marketplace, driven by a pure-TypeScript scoring algorithm that weighs five factors against their saved preferences.
Closes #230
What's changed
Core algorithm —
lib/matching.tsWeighted composite score (0–100) per invoice across five sub-scores:
Risk profile flips the direction of the risk sub-score so aggressive lenders are rewarded for taking on riskier invoices, conservative lenders penalised. Hard amount filters run before scoring. 1 000 invoices score in ~1 ms — well under the 100 ms requirement.
Types —
src/types/matching.tsLenderPreferences,MatchResult,ScoreBreakdown,MatchQuality, and bigint-safe serialisation helpers for localStorage. Re-exported from the existing@/typesbarrel.Hooks
useLenderPreferences— two-tier persistence: localStorage (instant, always available) + Supabaselender_preferencestable (when authenticated, so preferences survive device switches). Explicitsave()trigger avoids unintended round-trips.useMatchedInvoices— TanStack Query for raw invoice + originator history queries,useMemofor the scoring pass so preference changes re-score without a network fetch.Components
LenderPreferencesForm— shadcnDialog+react-hook-form+Zodvalidation. SegmentedOptionButtoncontrols for risk profile and currency, numeric inputs for min yield, amount bounds, and max due-date horizon.MatchQualityBadge— four tiers (★ Excellent / ✓ Good / ~ Fair / ○ Poor) with distinct colour coding.SuggestedMatches— responsive grid of ranked invoice cards, each with a hover/focus score breakdown panel showing per-factor bars (risk, currency, yield, history, duration), loading skeletons, empty state, and a "Browse all" override button.Marketplace integration —
