The assessment identifies critical integration risks, data integrity concerns, and rollback complexities inherent in brownfield development. + +**Overall Risk Level**: **MEDIUM-HIGH** +**Primary Concerns**: Foreign key dependencies, existing table integration, rollback complexity + +--- + +## Risk Categories + +### 1. Technical Risks + +| Risk ID | Probability | Impact | Severity | Description | +|---------|-------------|--------|----------|-------------| +| **T-01** | High | High | **CRITICAL** | **Foreign Key Constraint Failures**
Foreign keys to `templates` and `submissions` tables may fail if referenced records don't exist during migration or if existing data violates constraints. | +| **T-02** | Medium | High | **HIGH** | **Migration Rollback Complexity**
Rollback may fail due to foreign key dependencies or data integrity issues, requiring manual database intervention. | +| **T-03** | Low | High | **MEDIUM** | **Database Compatibility Issues**
Schema may not be compatible with all supported databases (PostgreSQL/MySQL/SQLite) due to JSONB usage or specific syntax. | +| **T-04** | Medium | Medium | **MEDIUM** | **Index Creation Performance**
Creating indexes on large existing tables may cause significant downtime or locking. | +| **T-05** | Low | Medium | **LOW** | **Schema Version Mismatch**
Migration timestamp conflicts with existing migrations in production. | + +**Mitigation Strategies:** +- **T-01**: Add `ON DELETE CASCADE` or `ON DELETE SET NULL` to foreign keys; validate existing data before migration +- **T-02**: Test rollback in staging environment; create backup before migration; use transaction wrapper +- **T-03**: Test migration on all three database types; use Rails 7+ compatible syntax +- **T-04**: Create indexes concurrently (PostgreSQL); schedule migration during low-traffic period +- **T-05**: Use unique timestamp prefix; verify migration order in production + +--- + +### 2. Integration Risks + +| Risk ID | Probability | Impact | Severity | Description | +|---------|-------------|--------|----------|-------------| +| **I-01** | **HIGH** | **HIGH** | **CRITICAL** | **Template Reference Integrity**
`cohorts.template_id` references `templates.id`. If templates are deleted or archived, foreign key constraint may prevent cohort creation or cause orphaned records. | +| **I-02** | **HIGH** | **HIGH** | **CRITICAL** | **Submission Reference Integrity**
`cohort_enrollments.submission_id` references `submissions.id`. Existing DocuSeal workflows may delete submissions, breaking enrollment links. | +| **I-03** | Medium | High | **HIGH** | **Account Table Confusion**
PRD specifies single `institutions` table, but DocuSeal has `accounts` table. Risk of confusion or unintended cross-references. | +| **I-04** | Medium | Medium | **MEDIUM** | **Existing Query Performance Degradation**
New indexes or table locks may slow down existing DocuSeal queries (templates, submissions, submitters). | +| **I-05** | Low | Medium | **LOW** | **Active Storage Conflicts**
New tables may conflict with Active Storage naming conventions or attachment behaviors. | + +**Mitigation Strategies:** +- **I-01**: Add `restrict_with_exception` to prevent template deletion if cohorts exist; implement soft deletes on templates +- **I-02**: Use `dependent: :restrict_with_exception` on CohortEnrollment submission reference; ensure submission lifecycle is managed +- **I-03**: Document clearly that `institutions` is independent of `accounts`; no foreign key relationship +- **I-04**: Run EXPLAIN ANALYZE on critical queries; monitor query plans after migration +- **I-05**: Verify Active Storage table names don't conflict; use explicit table names if needed + +--- + +### 3. Data Integrity Risks + +| Risk ID | Probability | Impact | Severity | Description | +|---------|-------------|--------|----------|-------------| +| **D-01** | Medium | **HIGH** | **HIGH** | **Unique Constraint Violations**
`cohort_enrollments` has unique constraints on `[cohort_id, student_email]` and `[submission_id]`. Existing data may violate these. | +| **D-02** | Medium | High | **HIGH** | **NOT NULL Constraint Failures**
Required fields (`institution_id`, `template_id`, `student_email`) may receive NULL values during bulk operations. | +| **D-03** | Low | High | **MEDIUM** | **JSONB Data Validation**
JSONB fields (`required_student_uploads`, `cohort_metadata`, `uploaded_documents`, `values`) may contain invalid JSON or unexpected structures. | +| **D-04** | Low | Medium | **LOW** | **Timestamp Field Consistency**
`deleted_at` soft delete pattern may conflict with existing `archived_at` pattern in DocuSeal tables. | +| **D-05** | Medium | Medium | **MEDIUM** | **Default Value Issues**
Default values for `status` fields may not align with business logic (e.g., 'draft' vs 'waiting'). | + +**Mitigation Strategies:** +- **D-01**: Test unique constraints with duplicate data; add database-level validation before migration +- **D-02**: Add model-level validations; use `null: false` in migration with proper defaults +- **D-03**: Add JSON schema validation in models; use `validate: :json_schema` if available +- **D-04**: Standardize on `deleted_at` for new tables; document pattern for future consistency +- **D-05**: Review business requirements for default states; add comments in migration + +--- + +### 4. Security Risks + +| Risk ID | Probability | Impact | Severity | Description | +|---------|-------------|--------|----------|-------------| +| **S-01** | Medium | High | **HIGH** | **Unauthorized Cross-Institution Data Access**
If multi-tenancy is accidentally enabled, students/sponsors may access data from other institutions. | +| **S-02** | Low | High | **MEDIUM** | **Email Data Exposure**
`sponsor_email` and `student_email` stored in plaintext; may violate privacy policies (POPIA). | +| **S-03** | Medium | Medium | **MEDIUM** | **Foreign Key Privilege Escalation**
Malicious user could potentially manipulate foreign keys to access unauthorized submissions or templates. | +| **S-04** | Low | Medium | **LOW** | **Soft Delete Data Leakage**
Soft-deleted records (`deleted_at`) may still be queryable by users with direct database access. | + +**Mitigation Strategies:** +- **S-01**: Add institution_id validation in all model scopes; enforce single institution in application logic +- **S-02**: Implement email encryption at rest using Rails `encrypts` method; review POPIA compliance +- **S-03**: Implement proper authorization (Cancancan) for all foreign key references; validate ownership +- **S-04**: Implement default scopes to filter deleted records; use paranoia gem for soft deletes + +--- + +### 5. Performance Risks + +| Risk ID | Probability | Impact | Severity | Description | +|---------|-------------|--------|----------|-------------| +| **P-01** | Medium | High | **HIGH** | **Query Performance Degradation**
Joining new tables with existing tables may slow down critical workflows (cohort dashboard, enrollment lists). | +| **P-02** | Medium | Medium | **MEDIUM** | **Migration Execution Time**
Creating tables with multiple indexes and foreign keys may exceed 30-second threshold. | +| **P-03** | Low | Medium | **LOW** | **JSONB Query Performance**
Querying JSONB fields (`cohort_metadata`, `values`) may be slower than structured columns. | +| **P-04** | Low | Low | **LOW** | **Index Bloat**
Multiple indexes on small tables may cause unnecessary overhead. | + +**Mitigation Strategies:** +- **P-01**: Use EXPLAIN ANALYZE to optimize queries; implement eager loading; add composite indexes +- **P-02**: Test migration timing in staging; use `disable_ddl_transaction!` for index creation if needed +- **P-03**: Use JSONB operators efficiently; consider partial indexes on frequently queried JSONB fields +- **P-04**: Monitor index usage after deployment; remove unused indexes + +--- + +### 6. Business Logic Risks + +| Risk ID | Probability | Impact | Severity | Description | +|---------|-------------|--------|----------|-------------| +| **B-01** | Medium | High | **HIGH** | **State Machine Complexity**
5-step cohort workflow (draft → active → completed) with multiple datetime fields may lead to inconsistent state transitions. | +| **B-02** | Medium | Medium | **MEDIUM** | **Single Institution Constraint**
PRD requires single institution per deployment, but schema doesn't enforce this at database level. | +| **B-03** | Low | Medium | **LOW** | **Program Type Validation**
`program_type` field accepts free text; may lead to inconsistent data (learnership vs learner-ship). | +| **B-04** | Medium | Medium | **MEDIUM** | **Sponsor Email Uniqueness**
Multiple cohorts may share sponsor email; may cause confusion in notifications. | + +**Mitigation Strategies:** +- **B-01**: Implement state machine gem (aasm); add validation callbacks; create state transition tests +- **B-02**: Add application-level singleton pattern; database constraint with CHECK or trigger +- **B-03**: Use enum or strict validation for program_type; add enum to model +- **B-04**: Add business logic validation; consider separate sponsor table if needed + +--- + +### 7. Rollback & Recovery Risks + +| Risk ID | Probability | Impact | Severity | Description | +|---------|-------------|--------|----------|-------------| +| **R-01** | **HIGH** | **HIGH** | **CRITICAL** | **Failed Rollback Due to Data Dependencies**
If enrollments reference submissions that are deleted during rollback, migration may fail. | +| **R-02** | Medium | High | **HIGH** | **Data Loss During Rollback**
Rollback will drop all new tables, losing any data created during testing or partial deployment. | +| **R-03** | Low | High | **MEDIUM** | **Schema.rb Desynchronization**
Failed migration may leave schema.rb out of sync with actual database state. | +| **R-04** | Medium | Medium | **MEDIUM** | **Production Rollback Complexity**
Rollback in production requires coordination, downtime, and potential data recovery. | + +**Mitigation Strategies:** +- **R-01**: Test rollback with sample data; add `dependent: :restrict_with_exception` to prevent orphaned records +- **R-02**: Create database backup before migration; document data retention policy; test in staging first +- **R-03**: Run `bin/rails db:schema:dump` after failed migration; manually verify schema.rb +- **R-04**: Create detailed rollback playbook; schedule maintenance window; have database administrator on standby + +--- + +## Risk Severity Matrix + +### Critical Risks (Immediate Action Required) +1. **T-01**: Foreign Key Constraint Failures +2. **I-01**: Template Reference Integrity +3. **I-02**: Submission Reference Integrity +4. **R-01**: Failed Rollback Due to Data Dependencies + +### High Risks (Requires Mitigation Before Deployment) +1. **T-02**: Migration Rollback Complexity +2. **D-01**: Unique Constraint Violations +3. **D-02**: NOT NULL Constraint Failures +4. **S-01**: Unauthorized Cross-Institution Data Access +5. **P-01**: Query Performance Degradation +6. **B-01**: State Machine Complexity + +### Medium Risks (Monitor and Address) +1. **T-03**: Database Compatibility Issues +2. **T-04**: Index Creation Performance +3. **I-03**: Account Table Confusion +4. **I-04**: Existing Query Performance Degradation +5. **S-02**: Email Data Exposure +6. **S-03**: Foreign Key Privilege Escalation +7. **P-02**: Migration Execution Time +8. **B-02**: Single Institution Constraint +9. **B-04**: Sponsor Email Uniqueness +10. **R-02**: Data Loss During Rollback +11. **R-04**: Production Rollback Complexity + +### Low Risks (Acceptable or Future Mitigation) +1. **T-05**: Schema Version Mismatch +2. **I-05**: Active Storage Conflicts +3. **D-04**: Timestamp Field Consistency +4. **D-05**: Default Value Issues +5. **S-04**: Soft Delete Data Leakage +6. **P-03**: JSONB Query Performance +7. **P-04**: Index Bloat +8. **B-03**: Program Type Validation +9. **R-03**: Schema.rb Desynchronization + +--- + +## Integration Verification Requirements + +### IV1: Existing DocuSeal Tables Remain Unchanged +**Risk**: **HIGH** -
