+# Certificate Upload & Verification Workflow
+
+This document outlines the standardized workflow for handling certificate uploads, metadata capture, and persistence within the Krow mobile application. The certificates module follows the same layered architecture as the `documents` module (see `documents/IMPLEMENTATION_WORKFLOW.md`), with key differences to accommodate certificate-specific metadata (expiry date, issuer, certificate number, type).
+
+## 1. Overview
+
+The workflow follows a 4-step lifecycle:
+
+1. **Form Entry**: The user fills in certificate metadata (name, type, issuer, certificate number, expiry date).
+2. **File Selection**: Picking a PDF, JPG, or PNG file locally via `FilePickerService`.
+3. **Attestation**: Requiring the user to confirm the certificate is genuine before submission.
+4. **Upload & Persistence**: Pushing the file to storage, initiating background verification, and saving the record to the database via Data Connect.
+
+---
+
+## 2. Technical Stack
+
+| Service | Responsibility |
+|---------|----------------|
+| `FilePickerService` | PDF/image file selection from device |
+| `FileUploadService` | Uploads raw files to secure cloud storage |
+| `SignedUrlService` | Generates secure internal links for verification access |
+| `VerificationService` | Orchestrates AI or manual verification (category: `CERTIFICATE`) |
+| `DataConnect` (Firebase) | Persists structured data and verification metadata via `upsertStaffCertificate` |
+
+---
+
+## 3. Key Difference vs. Documents Module
+
+| Aspect | Documents | Certificates |
+|--------|-----------|--------------|
+| Metadata captured | None (just a file) | `name`, `type` (`ComplianceType`), `expiryDate`, `issuer`, `certificateNumber` |
+| Accepted file types | `pdf` only | `pdf`, `jpg`, `png` |
+| Verification category | `DOCUMENT` | `CERTIFICATE` |
+| Domain entity | `StaffDocument` | `StaffCertificate` |
+| Status enum | `DocumentStatus` | `StaffCertificateStatus` |
+| Validation status | `DocumentVerificationStatus` | `StaffCertificateValidationStatus` |
+| Repository | `DocumentsRepository` | `CertificatesRepository` |
+| Data Connect method | `upsertStaffDocument` | `upsertStaffCertificate` |
+| Navigator helper | `StaffNavigator.toDocumentUpload` | `StaffNavigator.toCertificateUpload` |
+
+---
+
+## 4. Implementation Status
+
+### ✅ Completed — Presentation Layer
+
+#### Routing
+- `StaffPaths.certificateUpload` constant used in `StaffPaths.childRoute` within `StaffCertificatesModule`.
+- `StaffNavigator.toCertificateUpload({StaffCertificate? certificate})` type-safe navigation helper wires the route argument.
+
+#### Domain Layer
+- `CertificatesRepository` interface defined with three methods:
+  - `getCertificates()` — fetch the current staff member's certificates.
+  - `uploadCertificate(...)` — upload file + trigger verification + persist record.
+  - `upsertCertificate(...)` — metadata-only update (no file re-upload).
+  - `deleteCertificate(...)` — remove a certificate by `ComplianceType`.
+- `UploadCertificateUseCase` wraps `uploadCertificate`; takes `UploadCertificateParams`:
+  - `certificationType` (`ComplianceType`) — required
+  - `name` (`String`) — required
+  - `filePath` (`String`) — required
+  - `expiryDate` (`DateTime?`) — optional
+  - `issuer` (`String?`) — optional
+  - `certificateNumber` (`String?`) — optional
+- `GetCertificatesUseCase` wraps `getCertificates()`.
+- `UpsertCertificateUseCase` wraps `upsertCertificate()` for metadata-only saves.
+- `DeleteCertificateUseCase` wraps `deleteCertificate()`.
+
+#### State Management
+- `CertificateUploadStatus` enum: `initial | uploading | success | failure`
+- `CertificateUploadState` (Equatable): tracks `status`, `isAttested`, `updatedCertificate`, `errorMessage`
+- `CertificateUploadCubit`:
+  - Guards upload behind `state.isAttested == true`.
+  - On success: emits `success` with the returned `StaffCertificate`.
+  - On failure: emits `failure` with the error message key via `BlocErrorHandler`.
+
+#### UI — `CertificateUploadPage`
+
+Accepts an optional `StaffCertificate? certificate` as a route argument. When provided, the form is pre-populated for editing; when `null`, the page is in "new certificate" mode.
+
+**Form fields:**
+- **Certificate Name** (`TextEditingController _nameController`) — required.
+- **Certificate Type** (`ComplianceType? _selectedType`) — `DropdownButton`, defaults to `ComplianceType.other`.
+- **Issuer** (`TextEditingController _issuerController`) — optional.
+- **Certificate Number** (`TextEditingController _numberController`) — optional.
+- **Expiry Date** (`DateTime? _selectedExpiryDate`) — date picker; defaults to 1 year from today.
+
+**File selection:**
+- `FilePickerService.pickFile(allowedExtensions: ['pdf', 'jpg', 'png'])`.
+- Selected file path stored in `String? _selectedFilePath`.
+
+**Attestation & submission:**
+- Attestation checkbox must be checked before submitting (mirrors Documents pattern).
+- Submit button enabled only when: a file is selected AND attestation is checked.
+- Loading state: `CircularProgressIndicator` replaces the submit button while `CertificateUploadStatus.uploading`.
+- On `success`: shows `UiSnackbar` (success type) and calls `Modular.to.pop()`.
+- On `failure`: shows `UiSnackbar` (error type); stays on page for retry.
+
+**App bar:**
+- `UiAppBar` with `certificate?.name ?? t.staff_certificates.upload_modal.title` as title.
+
+#### UI Guidelines (Consistent with Documents)
+Follow the same patterns defined in `documents/IMPLEMENTATION_WORKFLOW.md §3`:
+1. **Header & Instructions**: `UiAppBar` title = certificate name (or modal title). Body instructions use `UiTypography.body1m.textPrimary`.
+2. **File Selection Card**:
+   - Empty: neutral/primary bordered card inviting file pick.
+   - Selected: `UiColors.bgPopup` card with `UiConstants.radiusLg` rounding, `UiColors.primary` border, truncated file name, and explicit "Replace" action.
+3. **Bottom Footer / Attestation**: Fixed to `bottomNavigationBar` inside `SafeArea` + `Padding`; submit state tightly coupled to both file presence and attestation.
+
+#### Module Wiring — `StaffCertificatesModule`
+
+Binds (all lazy singletons unless noted):
+| Binding | Scope |
+|---------|-------|
+| `CertificatesRepository` → `CertificatesRepositoryImpl` | Lazy singleton |
+| `GetCertificatesUseCase` | Lazy singleton |
+| `DeleteCertificateUseCase` | Lazy singleton |
+| `UpsertCertificateUseCase` | Lazy singleton |
+| `UploadCertificateUseCase` | Lazy singleton |
+| `CertificatesCubit` | Lazy singleton |
+| `CertificateUploadCubit` | **Per-use** (non-singleton via `i.add<>`) |
+
+Routes:
+- `StaffPaths.childRoute(StaffPaths.certificates, StaffPaths.certificates)` → `CertificatesPage`
+- `StaffPaths.childRoute(StaffPaths.certificates, StaffPaths.certificateUpload)` → `CertificateUploadPage(certificate: r.args.data is StaffCertificate ? … : null)`
+
+#### `CertificatesPage` Integration
+- `CertificateCard.onTap` navigates to `CertificateUploadPage` with the `StaffCertificate` as route data.
+- After returning from the upload page, `loadCertificates()` is awaited to refresh the list (fixes `unawaited_futures` lint).
+
+#### Localization
+- Keys live under `staff_certificates.*` in `en.i18n.json` and `es.i18n.json`.
+- Relevant keys: `upload_modal.title`, `upload_modal.success_snackbar`, `upload_modal.name_label`, `upload_modal.replace`, `error_loading`.
+- Codegen: `dart run slang` generates `TranslationsStaffCertificatesEn` and its Spanish counterpart.
+
+---
+
+### ✅ Completed — Data Layer
+
+#### Data Connect Integration
+- `StaffConnectorRepository` interface includes `getStaffCertificates()` and `upsertStaffCertificate()`.
+- `deleteStaffCertificate(certificationType:)` implemented for certificate removal.
+- SDK regenerated via: `make dataconnect-generate-sdk ENV=dev`.
+
+#### Repository Implementation — `CertificatesRepositoryImpl`
+
+Constructor injects `FileUploadService`, `SignedUrlService`, `VerificationService`; uses `DataConnectService.instance` for Data Connect calls.
+
+**`uploadCertificate()` — 5-step orchestration:**
+
+```
+1. FileUploadService.uploadFile(...)
+     → fileName: 'staff_cert_<type>_<timestamp>.pdf'
+     → visibility: FileVisibility.private
+   Returns FileUploadResponse { fileUri }
+
+2. SignedUrlService.createSignedUrl(fileUri: uploadRes.fileUri)
+     → Generates an internal signed link for verification access
+
+3. VerificationService.createVerification(...)
+     → fileUri, type: certificationType.value
+     → category: 'CERTIFICATE'   ← distinguishes from DOCUMENT
+     → subjectType: 'STAFF'
+     → subjectId: await _service.getStaffId()
+
+4. StaffConnectorRepository.upsertStaffCertificate(...)
+     → certificationType, name, status: pending
+     → fileUrl: uploadRes.fileUri, expiry, issuer, certificateNumber
+     → validationStatus: pendingExpertReview
+
+5. getCertificates() → find & return the matching StaffCertificate
+```
+
+**`upsertCertificate()` — metadata-only update:**
+- Directly calls `upsertStaffCertificate(...)` without any file upload or verification step.
+- Used for editing certificate details after initial upload.
+
+**`deleteCertificate()` — record removal:**
+- Calls `deleteStaffCertificate(certificationType:)`.
+
+---
+
+## 5. State Management Reference
+
+```
+CertificateUploadStatus
+  ├── initial    — page just opened / form being filled
+  ├── uploading  — upload + verification in progress
+  ├── success    — certificate saved; navigate back (pop)
+  └── failure    — error; stay on page; show snackbar
+```
+
+**Cubit guards:**
+- Upload is blocked unless `state.isAttested == true`.
+- Submit button enabled only when both a file is selected AND attestation is checked.
+- Uses `BlocErrorHandler` mixin for consistent error emission.
+
+---
+
+## 6. StaffCertificateStatus Mapping Reference
+
+The backend uses a richer enum than the domain layer. Standard mapping:
+
+| Backend / Validation Status | Domain `StaffCertificateStatus` | Notes |
+|-----------------------------|----------------------------------|-------|
+| `VERIFIED` / `AUTO_PASS` / `APPROVED` | `verified` | Fully or AI-approved |
+| `UPLOADED` / `PENDING` / `PROCESSING` / `NEEDS_REVIEW` / `EXPIRING` | `pending` | Upload received; processing or awaiting renewal |
+| `AUTO_FAIL` / `REJECTED` / `ERROR` | `rejected` | AI or manual rejection / system error |
+| `MISSING` | `missing` | Not yet uploaded |
+
+`StaffCertificateValidationStatus` preserves the full backend granularity for detailed UI feedback (e.g., showing "Pending Expert Review" vs. "Auto-Failed").
+
+---
+
+## 7. Future Considerations
+
+1. **Expiry Notifications**: Certificates approaching expiry (domain status `pending` / backend `EXPIRING`) should surface a nudge in `CertificatesPage` or via push notification.
+2. **Re-verification on Edit**: When a certificate's file is replaced via `uploadCertificate`, a new verification job is triggered. Decide whether editing only metadata (via `upsertCertificate`) should also trigger re-verification.
+3. **Multiple Files per Certificate**: The current schema supports a single `fileUrl`. If multi-page certificates become a requirement, the Data Connect schema and `CertificatesRepository` interface will need extending.
+4. **Shared Compliance UI Components**: The file selection card and attestation footer patterns are duplicated between `DocumentUploadPage` and `CertificateUploadPage`. Consider extracting them into a shared `compliance_upload_widgets` package to reduce duplication.

+# Document Upload & Verification Workflow
+
+This document outlines the standardized workflow for handling file uploads, verification, and persistence within the Krow mobile application. This pattern is based on the `attire` module and is used as the reference for the `documents` and `certificates` modules.
+
+## 1. Overview
+
+The workflow follows a 4-step lifecycle:
+
+1. **Selection**: Picking a PDF file locally via `FilePickerService`.
+2. **Attestation**: Requiring the user to confirm the document is genuine before submission.
+3. **Upload & Verification**: Pushing the file to storage and initiating a background verification job.
+4. **Persistence**: Saving the record with its verification status to the database via Data Connect.
+
+---
+
+## 2. Technical Stack
+
+| Service | Responsibility |
+|---------|----------------|
+| `FilePickerService` | PDF/file selection from device |
+| `FileUploadService` | Uploads raw files to secure cloud storage |
+| `SignedUrlService` | Generates secure internal/public links for viewing |
+| `VerificationService` | Orchestrates AI or manual verification |
+| `DataConnect` (Firebase) | Persists structured data and verification metadata |
+
+---
+
+## 3. Implementation Status
+
+### ✅ Completed — Presentation Layer
+
+#### Routing
+- `StaffPaths.documentUpload` constant added to `core/lib/src/routing/staff/route_paths.dart`
+- `StaffNavigator.toDocumentUpload({required StaffDocument document})` type-safe navigation helper added to `core/lib/src/routing/staff/navigator.dart`
+
+#### Domain Layer
+- `DocumentsRepository.uploadDocument(String documentId, String filePath)` method added to the repository interface.
+- `UploadDocumentUseCase` created at `domain/usecases/upload_document_usecase.dart`, wrapping the repository call.
+- `UploadDocumentArguments` value object holds `documentId` and `filePath`.
+
+#### State Management
+- `DocumentUploadStatus` enum: `initial | uploading | success | failure`
+- `DocumentUploadState` (Equatable): tracks `status`, `isAttested`, `updatedDocument`, `errorMessage`
+- `DocumentUploadCubit`: guards upload behind attestation check; emits success/failure; typed result as `StaffDocument`
+
+#### UI — `DocumentUploadPage`
+- Accepts `StaffDocument document` and optional `String? initialUrl` as route arguments
+- Refactored into specialized widgets for maintainability:
+  - `DocumentFileSelector`: Handles the file picking logic and "empty state" UI.
+  - `DocumentSelectedCard`: Displays the selected file with "Replace" action.
+  - `DocumentAttestationCheckbox`: Isolated checkbox logic for legal confirmation.
+  - `DocumentUploadFooter`: Sticky bottom bar containing the checkbox and submission button.
+- PDF file picker via `FilePickerService.pickFile(allowedExtensions: ['pdf'])`
+- Attestation checkbox must be checked before the submit button is enabled
+- Loading state: shows `CircularProgressIndicator` while uploading (replaces button — mirrors attire pattern)
+- On success: shows `UiSnackbar` and calls `Modular.to.toDocuments()` to return to the list
+- On failure: shows `UiSnackbar` with error message; stays on page for retry
+
+#### UI Guidelines (For Documents & Certificates)
+To ensure a consistent experience across all compliance uploads (documents, certificates), adhere to the following UI patterns:
+1. **Header & Instructions:** Use `UiAppBar` with the item name as the title and description as the subtitle. Provide clear instructions at the top of the body (`UiTypography.body1m.textPrimary`).
+2. **File Selection Card:** 
+   - When empty: Show a neutral/primary bordered card inviting the user to pick a file.
+   - When selected: Show an elegant card with `UiColors.bgPopup`, rounded corners (`UiConstants.radiusLg`), bordered by `UiColors.primary`.
+   - The selected card must contain an identifying icon, the truncated file name, and an explicit inline action (e.g., "Replace" or "Upload") using `UiTypography.body3m.textSecondary`.
+   - **Do not** embed native PDF viewers or link out to external readers.
+3. **Bottom Footer / Attestation:**
+   - Fix the attestation checkbox and the submit button to the bottom using `bottomNavigationBar` wrapped in a `SafeArea` and `Padding`.
+   - The submit button state must be tightly coupled to both the file presence and the attestation state.
+
+#### Module Wiring — `StaffDocumentsModule`
+- `UploadDocumentUseCase` bound as lazy singleton
+- `DocumentUploadCubit` bound (non-singleton, per-use)
+- Upload route registered: `StaffPaths.documentUpload` → `DocumentUploadPage`
+- Route arguments extracted: `data['document']` as `StaffDocument`, `data['initialUrl']` as `String?`
+
+#### `DocumentsPage` Integration
+- `DocumentCard.onTap` now calls `Modular.to.toDocumentUpload(document: doc)` instead of the old placeholder `pushNamed('./details')`
+
+#### Localization
+- Added `staff_documents.upload.*` keys to `en.i18n.json` and `es.i18n.json`
+- Strings: `instructions`, `submit`, `select_pdf`, `attestation`, `success`, `error`
+- Codegen (`dart run slang`) produces `TranslationsStaffDocumentsUploadEn` and its Spanish counterpart
+
+#### DocumentStatus Mapping
+- `DocumentStatus` mapping is centralized in `StaffConnectorRepositoryImpl`, collapsing complex backend states into domain levels:
+  - `VERIFIED`, `AUTO_PASS`, `APPROVED` → `verified`
+  - `UPLOADED`, `PENDING`, `PROCESSING`, `NEEDS_REVIEW`, `EXPIRING` → `pending`
+  - `AUTO_FAIL`, `REJECTED`, `ERROR` → `rejected`
+  - `MISSING` → `missing`
+- A new `DocumentVerificationStatus` enum captures the full granularity of the backend state for detailed UI feedback (e.g., showing "Auto Fail" vs "Rejected").
+
+---
+
+### ✅ Completed — Data Layer
+ 
+ #### Data Connect Integration
+ - `StaffConnectorRepository` interface updated with `getStaffDocuments()` and `upsertStaffDocument()`.
+ - `upsertStaffDocument` mutation in `backend/dataconnect/connector/staffDocument/mutations.gql` updated to accept `verificationId`.
+ - `getStaffDocumentByKey` and `listStaffDocumentsByStaffId` queries updated to include `verificationId`.
+ - SDK regenerated: `make dataconnect-generate-sdk ENV=dev`.
+ 
+ #### Repository Implementation — `StaffConnectorRepositoryImpl`
+ - **`getStaffDocuments()`**: 
+   - Uses `Future.wait` to simultaneously fetch the full list of available `Document` types and the current staff's `StaffDocument` records.
+   - Maps the master list of `Document` entities, joining them with any existing `StaffDocument` entry.
+   - This ensures the UI always shows all required documents, even if they haven't been uploaded yet (status: `missing`).
+   - Populates `verificationId` and `verificationStatus` for presentation layer mapping.
+ - **`upsertStaffDocument()`**: 
+   - Handles the upsert (create or update) of a staff document record.
+   - Explicitly passes `documentUrl` and `verificationId`, ensuring metadata is persisted alongside the file reference.
+ - **Status Mapping**:
+   - `_mapDocumentStatus`: Collapses backend statuses into domain `verified | pending | rejected | missing`.
+   - `_mapFromDCDocumentVerificationStatus`: Preserves the full granularity of the backend status for the UI/presentation layer.
+ 
+ #### Feature Repository — `DocumentsRepositoryImpl`
+ - Fixed to ensure all cross-cutting services (`FileUploadService`, `VerificationService`) are properly orchestrated.
+ - **Verification Integration**: When a document is uploaded, a verification job is triggered, and its `verificationId` is saved to Data Connect immediately. This allows the UI to show a "Processing" state while the background job runs.
+
+---
+
+## 5. DocumentStatus Mapping Reference
+
+The backend uses a richer enum than the domain layer. The mapping is standardized as follows:
+
+| Backend `DocumentStatus` | Domain `DocumentStatus` | Notes |
+|--------------------------|-------------------------|-------|
+| `VERIFIED` | `verified` | Fully approved |
+| `AUTO_PASS` | `verified` | AI approved |
+| `APPROVED` | `verified` | Manually approved |
+| `UPLOADED` | `pending` | File received, not yet processed |
+| `PENDING` | `pending` | Queued for verification |
+| `PROCESSING` | `pending` | AI analysis in progress |
+| `NEEDS_REVIEW` | `pending` | AI unsure, human review needed |
+| `EXPIRING` | `pending` | Approaching expiry (treated as pending for renewal) |
+| `MISSING` | `missing` | Document not yet uploaded |
+| `AUTO_FAIL` | `rejected` | AI rejected |
+| `REJECTED` | `rejected` | Manually rejected |
+| `ERROR` | `rejected` | System error during verification |
+
+---
+
+## 6. State Management Reference
+
+```
+DocumentUploadStatus
+  ├── initial    — page just opened
+  ├── uploading  — upload + verification in progress
+  ├── success    — document saved; navigate back with result
+  └── failure    — error; stay on page; show snackbar
+```
+
+**Cubit guards:**
+- Upload is blocked unless `state.isAttested == true`
+- Button is only enabled when both a file is selected AND attestation is checked
+
+---
+
+## 7. Future Considerations: Certificates
+
+The implementation of the **Certificates** module should follow this exact pattern with a few key differences:
+1. **Repository**: Use `StaffConnectorRepository.getStaffCertificates()` and `upsertStaffCertificate()`.
+2. **Metadata**: Certificates often require an `expiryDate` and `issueingBody` which should be captured during the upload step if not already present in the schema.
+3. **Verification**: If using the same `VerificationService`, ensure the `category` is set to `CERTIFICATE` instead of `DOCUMENT` to trigger appropriate verification logic.
+4. **UI**: Mirror the `DocumentUploadPage` design but update the instructions and translation keys to reference certificates.
