+Below is a **“mental model”** of the Zero-UI variant extractor. distilled so that _another_ human (or LLM) can reason about, extend, or safely refactor the code-base.
+
+---
+
+## 1. Top-level goal
+
+- **Locate every call** to a user-supplied React hook
+
+  ```js
+  const [value, setterFn] = useUI('stateKey', 'initialValue');
+  ```
+
+- Statically discover **all possible string values** that flow into
+  `stateKey`, `initialValue`, and `setterFn()` arguments.
+  - `stateKey` can resolve to a local static string.
+  - `initialValue` is the same rule as above.
+  - `setterFn()` argument is many forms allowed (see table 3.1) but **must be resolvable**; otherwise the value is ignored (silent) _unless_ it looked resolvable but failed inside the helpers, in which case a targeted error is thrown.
+  - Imported bindings are never allowed - the dev must re-cast them through a local `const`.
+
+- Report the result as a list of `VariantData` objects.
+
+```ts
+type VariantData = {
+	key: string; // 'stateKey'
+	values: string[]; // ['light','dark',…]   (unique, sorted)
+	initialValue: string; // from 2nd arg of useUI()
+};
+```

+
+## 2. Two-pass pipeline
+
+| Pass                               | File-scope work                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        | Output                                                               |

+| **Pass 1 - `collectUseUISetters`** | 1. Traverse the AST once.<br>2. For each `useUI()` destructuring:<br>• validate shapes & count.<br>• resolve the **state key** and **initial value** with **`literalFromNode`** (see rules below).<br>• grab the **binding** of the setter variable.                                                                                                                                                                                                                                                                                   | `SetterMeta[]` = `{ binding, setterName, stateKey, initialValue }[]` |
+| **Pass 2 - `harvestSetterValues`** | 1. For every `binding.referencePaths` (i.e. every place the setter is used)<br>2. Only keep `CallExpression`s: `setX(…)`<br>3. Examine the first argument:<br>• direct literal / identifier / template → resolve via `literalFromNode`.<br>• conditional `cond ? a : b` → resolve both arms.<br>• logical fallback `a \|\| b`, `a ?? b` → resolve each side.<br>&nbsp;&nbsp; arrow / function bodies → collect every returned expression and resolve.<br>4.

+### 3.2 Helpers
+
+| Helper                            | Job                                                                                                                                                                           |
+| --------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
+| **`resolveTemplateLiteral`**      | Ensures every `${expr}` itself resolves to a string via `literalFromNode`.                                                                                                    |
+| **`resolveLocalConstIdentifier`** | Maps an `Identifier` → its `const` initializer _if_ that initializer is an accepted string/ template. Rejects imported bindings with a _single_ descriptive error.            |
+| **`resolveMemberExpression`**     | Static walk of `obj.prop`, `obj['prop']`, `obj?.prop`, etc. Works through `as const`, optional-chaining, arrays, numbers, nested chains. Throws if any hop can't be resolved. |
+| **`literalFromNode`**             | Router that calls the above; memoised (`WeakMap`) so each AST node is evaluated once.                                                                                         |
+
+All helpers accept `opts:{ throwOnFail, source, hook }` so _contextual_
+error messages can be emitted with **`throwCodeFrame`**
+(using `@babel/code-frame` to show a coloured snippet).
+
+---
+
+## 4. Validation rules (why errors occur)
+
+| Position in `useUI`      | Allowed value                                                                                                                                                                                                 | Example error                                 |
+| ------------------------ | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------------------------------------------- |
+| **stateKey (arg 0)**     | _Local_ static string                                                                                                                                                                                         | `State key cannot be resolved at build-time.` |
+| **initialValue (arg 1)** | Same rule as above.                                                                                                                                                                                           | `Initial value cannot be resolved …`          |
+| **setter argument**      | Many forms allowed (see table 3.1) but **must be resolvable**; otherwise the value is ignored (silent) _unless_ it looked resolvable but failed inside the helpers, in which case a targeted error is thrown. |                                               |
+
+Imported bindings are never allowed - the dev must re-cast them
+through a local `const`.
+
+---
+
+## 5. Optional-chain & optional-member details
+
+- The updated `resolveMemberExpression` loop iterates while
+  `isMemberExpression || isOptionalMemberExpression`.
+- Inside array/obj traversal it throws a clear error if a link is
+  missing instead of silently returning `null`.
+- `props` collects mixed `string | number` keys in **reverse** (deep → shallow) order, so they can be replayed from the root identifier outward.
+
+---
+
+## 6. Performance enhancements
+
+- **Memoisation** (`WeakMap<node,string\|null>`) across _both_ passes.
+- **Quick literals** - string & number keys handled without extra calls.
+- `throwCodeFrame` (and thus `generate(node).code`) runs **only** on
+  failing branches.
+- A small **LRU file-cache** (<5k entries) avoids re-parsing unchanged
+  files (mtime + size signature, with hash fallback).
+
+---
+
+## 7. What is **not** supported
+
+- Runtime-only constructs (`import.meta`, env checks, dynamic imports …).
+- Cross-file constant propagation - the extractor is intentionally
+  single-file to keep the build independent of user bundler config.
+- Non-string variants (numbers, booleans) - strings only.
+- Private class fields in member chains.
+- Setter arguments that are **imported functions**.
+
+---
+
+## 8. How to extend
+
+- **Add more expression kinds**: extend `literalFromNode` with new
+  cases _and_ unit-test them.
+- **Cross-file constants**: in `resolveLocalConstIdentifier`, detect
+  `ImportSpecifier`, read & parse the target file, then recurse - but
+  beware performance.
+- **Boolean / number variants**: relax `literalToString` and adjust
+  variant schema.
+
+---
+
+> **In one sentence**:
+> The extractor turns _purely static, in-file JavaScript_ around `useUI`
+> into a deterministic list of variant strings, throwing early and with
+> helpful frames whenever something would otherwise need runtime
+> evaluation.
