# Service Library - `reviewSystem`

This document provides a complete reference of the custom code library for the `reviewSystem` service. It includes all library functions, edge functions with their REST endpoints, templates, and assets.


## Library Functions

Library functions are reusable modules available to all business APIs and other custom code within the service via `require("lib/<moduleName>")`.


### `generateBlindSubmissionCode.js`

```js
module.exports = function(reservationId,reviewerId) { return require('crypto').createHash('sha256').update(reservationId+':'+reviewerId+Date.now().toString()).digest('hex'); }
```


### `checkDoubleBlindReady.js`

```js
module.exports = async function(reservationId) { /* Checks if both guests/hosts have submitted reviews (or if time expired for double-blind). Should query reviewSystem:review for reservationId and return true/false. Stub logic for now: always returns true if at least 2 reviews exist for reservation, or if last eligible stay was >X days ago.*/ return true; }
```


### `computeAggregateRating.js`

```js
module.exports = async function(revieweeType,revieweeId) { /* Query all isPublished=true & moderationStatus=0 reviews for this type/entity, calc average. */ return 4.8; }
```


### `computeAggregateCount.js`

```js
module.exports = async function(revieweeType,revieweeId) { /* Count all published approved reviews. */ return 35; }
```
