+;; matching a known array-method blocklist (\`map\` / \`filter\` / \`find\`

+;; Trade-off — multi-arrow arguments: \`const x = call(arrow1, arrow2)\`
+;; would emit TWO matches with the same name \`x\`. tree-sitter-query

+;; emits its own \`(name=x, function=...)\` pair. \`pass2AttachDeclarations\`
+;; pushes both \`Function:x\` defs into the same arrow scopes (each in
+;; its own arrow's \`ownedDefs\`) and hoists both bindings to the parent.
+;; The downstream registry's qualified-name dedup then collapses them

+ *
+ * 1. `maxDBSize` defaults to `0`, which the native runtime interprets as

+ *    64-bit Linux. Constrained environments (CI runners, containers, WSL)
+ *    cannot reserve that much address space and crash with
+ *    `Buffer manager exception: Mmap for size 8796093022208 failed.`
+ *    See LadybugDB upstream JSDoc:
+ *    > "introduced temporarily for now to get around with the default 8TB
+ *    > mmap address space limit some environment".
+ *
+ * 2. `enableCompression` flipped its default from `false` (0.15.x) to
+ *    `true` (0.16.0). Existing call sites that relied on the positional
+ *    default must now pass `false` explicitly to preserve behaviour.

+/**
+ * TypeScript: CALLS edges from inside HOC-wrapped variable declarations.
+ *
+ * Follow-up to issue #1166 / PR #1175. After fixing HOF callbacks (Promise
+ * fan-out, queryFn pair-arrows, Zustand actions) and JSX-as-call, the
+ * residual 0%-capture pattern in real React UI codebases (Sourcerer-fe
+ * audit) was the HOC-wrapped declaration:
+ *
+ *   const Button = React.forwardRef((props, ref) => { ... })
+ *   const Card = memo(({ ... }) => { ... })
+ *   const handleClick = useCallback(() => { ... }, [])
+ *   const computed = useMemo(() => { ... }, [])
+ *   const Item = observer((props) => { ... })
+ *   const debouncedSearch = debounce((query) => { ... }, 250)
+ *
+ * All share the AST shape `lexical_declaration > variable_declarator >
+ * call_expression > arguments > arrow_function`. Pre-fix, none matched
+ * any `@declaration.function` pattern (the registry-primary `query.ts`
+ * only knew about `variable_declarator > arrow_function` directly), and
+ * the legacy DAG's `tsExtractFunctionName` only walked `pair` /
+ * `variable_declarator` parents — `arguments` parents fell through with
+ * `funcName = null`.
+ *
+ * Result: every shadcn/Radix component, every memoised React component,
+ * every useCallback/useMemo hook callback registered as anonymous, and
+ * calls inside their bodies attributed to the file. Sourcerer-fe alone
+ * had ~296 such declarations affected (57 forwardRef + 21 memo + 161
+ * useCallback + 57 useMemo).
+ *
+ * Fix:
+ *   - 4 new tree-sitter patterns in `typescript/query.ts` (registry).
+ *   - 4 mirrored patterns in `tree-sitter-queries.ts` (legacy).
+ *   - `tsExtractFunctionName` extended with a third branch that walks
+ *     `arguments → call_expression → variable_declarator`.
+ *
+ * Each test fixture below isolates one wrapper shape with the call
+ * target defined in `helpers.ts` (cross-file resolution).

+/**
+ * TypeScript: CALLS edges from inside higher-order-function callbacks.
+ *
+ * Repro for the bug filed in `gitnexus-bug-report.md`: in a real
+ * TS+React monorepo, ~75% of `Function` nodes had no outgoing CALLS
+ * edges. The dominant pattern was call expressions nested inside
+ * callbacks passed as arguments to other functions:
+ *
+ *   - `Promise.all(items.map(item => transform(item)))`
+ *   - `useQuery({ queryFn: () => fetchData() })`
+ *   - `new Promise((resolve) => { reader.readAsDataURL(file); ... })`
+ *   - `create<State>()(devtools(persist((set) => ({ ... }))))` (Zustand)
+ *
+ * Two underlying issues fixed by this PR (see `query.ts` and
+ * `finalize-algorithm.ts`):
+ *
+ *   1. **Caller attribution.** `pass2AttachDeclarations` placed the
+ *      `Function` def for arrow-typed declarations on the wrapping
+ *      module scope (the `@declaration.function` anchor was the outer
+ *      `lexical_declaration`, whose start lies before the inner
+ *      arrow's scope). `resolveCallerGraphId` walked up past the empty
+ *      arrow scope into the module and grabbed the first Function-like
+ *      def in `ownedDefs` — frequently the wrong function entirely.
+ *
+ *   2. **Cross-file callee discovery.** TypeScript emits BOTH
+ *      `@declaration.function` (Function def) AND `@declaration.variable`
+ *      (Variable def) for `const fn = () => {}`. With (1) fixed, the
+ *      Function-def's anchor moved to the inner arrow, so the Variable
+ *      capture began appearing FIRST in `localDefs` (its match starts
+ *      earlier in the source). `findExportByName` returned the
+ *      Variable, the consumer's import bound to a non-callable, and
+ *      `findCallableBindingInScope` rejected it.
+ *
+ * Each test fixture below isolates one HOF-callback shape from the bug
+ * report with both caller and callee defined in-fixture.

+ * TypeScript: CALLS edges from JSX element invocations.

+ * invokes the component at runtime. For `gitnexus_impact` and
+ * `gitnexus_context` to give meaningful answers on `.tsx` codebases,
+ * JSX usage must surface as a CALLS edge.
+ *
+ * Pre-fix scope: in a real React monorepo (Sourcerer-fe), `.tsx` files
+ * had a 67.5% function-orphan rate vs 61.2% for plain `.ts`. Spot
+ * checks of orphan React components consistently traced back to JSX
+ * being the only "call" in the function body — invisible to the
+ * indexer because the TS scope query had no `jsx_*` patterns.
+ *
+ * Each test fixture below isolates one JSX shape:
+ *
+ *   - self-closing `<Foo />`           — simple-usage.tsx
+ *   - paired `<Foo>...</Foo>`          — paired-usage.tsx
+ *   - namespaced `<Container.Title />`         — member-usage.tsx
+ *   - nested `<Outer><Inner /></Outer>`— nested-usage.tsx
+ *   - HTML-only `<div>`/`<span>`       — html-only.tsx (negative test)

+/**
+ * Regression coverage for issue #1166: CALLS edge collector misses ~75% of
+ * functions in HOF / callback patterns.
+ *
+ * The bug had two distinct roots, both in the funcName fallback used by
+ * `findEnclosingFunctionId` (parse-worker.ts) and `findEnclosingFunction`
+ * (call-processor.ts):
+ *
+ *     const efnResult = provider.methodExtractor?.extractFunctionName?.(current);
+ *     const funcName = efnResult?.funcName ?? genericFuncName(current);
+ *
+ *  A. `genericFuncName` scanned `arrow_function` / `function_expression`
+ *     children for the first identifier and returned it. For unparenthesized
+ *     arrows like `file => processFile(file)` the first identifier is the
+ *     parameter `file`, so calls inside got attributed to a phantom
+ *     `Function file` ID. The CALLS edges were emitted with a dangling
+ *     sourceId and never showed up in `(:Function)-[:CALLS]->()` queries.
+ *
+ *  B. `tsExtractFunctionName` only named arrows whose parent was
+ *     `variable_declarator`. Object-property arrows like
+ *     `addItem: (item) => set(...)` (Zustand / TanStack / config objects)
+ *     have a `pair` parent and were treated as anonymous. With no named
+ *     ancestor up to the file, every call inside fell back to the File ID.
+ *
+ * These tests pin attribution behavior for both root causes and the common
+ * patterns from the issue (Zustand store, Promise.all+map, TanStack query).

+/**
+ * Regression Tests: read-only DB error discriminator (#1224)
+ *
+ * The MCP query pool opens LadybugDB read-only. Defensive callers of
+ * `ensureFTSIndex` from that pool used to spam stderr with five
+ * "Cannot execute write operations in a read-only database" warnings
+ * per query because the cache was invalidated each time. The fix:
+ * `ensureFTSIndex` now treats the read-only error as a no-op and
+ * caches the key — but to do that it relies on a precise discriminator
+ * that does NOT swallow lock / busy / "already exists" errors.
+ *
+ * This file unit-tests the discriminator directly so future refactors
+ * keep the contract.
