The Evidence Forms module provides a robust system for managing and processing various types of evidence submissions within an organization. It defines a set of pre-built forms, handles their submission, validation, file uploads, and review processes. This module integrates with authentication and attachment services to ensure secure and efficient evidence management.
At a high level, the system allows users to submit structured data and associated files for different evidence types (e.g., meeting minutes, policy documents). Authorized personnel can then review these submissions, approving or rejecting them with reasons. All interactions are secured through JWT or API key authentication and scoped to specific organizations.
## Architecture Overview
The Evidence Forms module follows a standard NestJS architecture, comprising a Controller, Service, and Module. It leverages shared definitions for form structures and integrates with other core services like `AttachmentsService` for file management and the database (`@trycompai/db`) for persistence.
The `EvidenceFormsController` exposes RESTful API endpoints, handling incoming HTTP requests. These requests are then delegated to the `EvidenceFormsService`, which encapsulates the business logic, data validation, and interactions with the database and other services. The `EvidenceFormsModule` orchestrates these components, declaring dependencies and making the service available for injection.

## Data Structures and Definitions
The core of the Evidence Forms system relies on well-defined data structures, primarily sourced from a shared `@comp/company` package. These definitions dictate the structure of forms, their fields, and the schema for submissions.
### Form Definitions
Key definitions include:
* `evidenceFormTypeSchema`: A Zod schema for validating the type of an evidence form (e.g., 'meeting', 'policy').
* `evidenceFormDefinitions`: An object mapping `EvidenceFormType` to its detailed `EvidenceFormDefinition`.
* `evidenceFormDefinitionList`: An array of all available `EvidenceFormDefinition` objects.
* `evidenceFormSubmissionSchemaMap`: A map where each `EvidenceFormType` is associated with its specific Zod schema for validating submission payloads.
* `EvidenceFormFieldDefinition`: Describes a single field within an evidence form, including its key, type (e.g., 'text', 'file', 'matrix'), and validation rules.
* `EvidenceFormDefinition`: Defines an entire evidence form, including its `type`, `name`, `description`, `fields`, and `submissionDateMode`.

- [apps/api/src/evidence-forms/evidence-forms.definitions.ts:1-10](https://github.com/blade47/comp/blob/main/apps/api/src/evidence-forms/evidence-forms.definitions.ts#L1-L10)
- [apps/api/src/evidence-forms/evidence-forms.service.ts:10-16](https://github.com/blade47/comp/blob/main/apps/api/src/evidence-forms/evidence-forms.service.ts#L10-L16)
### Validation Schemas
The service uses Zod for robust input validation:
* `listQuerySchema`: Validates query parameters for listing submissions (search, limit, offset).
* `uploadSchema`: Validates parameters for file uploads (formType, fileName, fileType, fileData).
* `reviewSchema`: Validates the payload for reviewing a submission (action: 'approved' | 'rejected', reason).
```typescript
// Example: listQuerySchema
const listQuerySchema = z.object({
search: z.string().trim().optional(),
limit: z.coerce.number().int().min(1).max(200).optional().default(50),
offset: z.coerce.number().int().min(0).optional().default(0),
});
```

## Core Service Logic (`EvidenceFormsService`)
The `EvidenceFormsService` handles all business logic related to evidence forms.
### Authentication and Authorization
The service enforces strict access control:
* `requireJwtUser(authContext: AuthContext)`: Ensures the request is authenticated via JWT and has a `userId`. API key authentication is explicitly denied for operations requiring a user context.
* `requirePrivilegedEvidenceAccess(authContext: AuthContext)`: Builds upon `requireJwtUser` by checking if the authenticated user possesses one of the `EVIDENCE_FORM_REVIEWER_ROLES` (`owner`, `admin`, `auditor`). This is crucial for operations like reviewing submissions or exporting data.
The `EVIDENCE_FORM_REVIEWER_ROLES` constant defines which user roles are authorized to perform privileged actions on evidence forms.

### File Handling
The service provides functionality for uploading and managing files associated with evidence forms.
* `decodeBase64File(fileData: string)`: Decodes a base64 encoded file string into a Buffer, performing basic validation on the input format and size.
* `uploadFile(params: { ... })`: Handles the entire file upload process. It validates the input payload, decodes the base64 file data, checks against size limits (`MAX_UPLOAD_FILE_SIZE_BYTES`, `MAX_UPLOAD_BASE64_LENGTH`), and then delegates to `AttachmentsService` to upload the file to S3 and generate a presigned download URL.
Uploaded files are subject to a maximum size limit of 100MB. This is enforced both by checking the base64 string length and the decoded file buffer length.

### Data Transformation and Export
Several utility functions facilitate data manipulation, especially for CSV export:
* `toCsvRow(values: string[])`: Converts an array of strings into a CSV row, handling proper escaping of double quotes.
* `flattenValue(value: unknown)`: Converts various data types (objects, numbers, booleans, strings) into a string representation suitable for CSV. Special handling is included for file objects to return their download URL.
* `flattenMatrixRows(value: unknown, field: EvidenceFormFieldDefinition)`: Specifically designed to flatten data from 'matrix' type form fields into a readable string format for CSV.
* `normalizeSubmissionFormType(submission: T)`: Transforms the internal database `DbEvidenceFormType` to the external `EvidenceFormType` for API responses.

### Submission and Review Workflow
The service manages the lifecycle of evidence form submissions.
**Key methods:**
* `listForms()`: Returns a list of all available evidence form definitions.
* `getFormStatuses(organizationId: string)`: Retrieves the latest submission date for each form type within a given organization.
* `getFormWithSubmissions(params: { ... })`: Fetches a specific form definition along with its submissions for an organization. Requires privileged access and supports search, pagination.
* `getSubmission(params: { ... })`: Retrieves a single evidence form submission by ID. Requires privileged access.
* `submitForm(params: { ... })`: Creates a new evidence form submission. It validates the payload against the form's schema, handles automatic submission date population, and stores the data in the database.
* `reviewSubmission(params: { ... })`: Allows privileged users to approve or reject a pending submission. Requires a reason for rejection.
* `getMySubmissions(params: { ... })`: Retrieves all submissions made by the currently authenticated user.
* `getPendingSubmissionCount(params: { ... })`: Returns the count of pending submissions for the authenticated user.
* `exportCsv(params: { ... })`: Exports all submissions for a specific form type within an organization to a CSV format. This method requires privileged access and uses the data transformation utilities (`flattenValue`, `flattenMatrixRows`, `toCsvRow`) to format the output. It also generates presigned URLs for any attached files.

## API Endpoints (`EvidenceFormsController`)
The `EvidenceFormsController` exposes a set of RESTful API endpoints for interacting with the evidence forms system. All endpoints are protected by `HybridAuthGuard` and require an `X-Organization-Id` header.
