# Professional Training: Event Registration Using Laravel

## Summary
A event registration blueprint for professional training built with Laravel on Ample.  
Domain schema:  
- **course_groups** (certification, cohort, start_at, end_at): certification cohorts;  
- **memberships** (course_group_id, participant_email, employer, role): participants and trainers;  
- **sessions** (course_group_id, starts_at, module, location_or_link): training sessions;  
- **materials** (course_group_id, module, object_key, visibility): course materials and exam guides;  
- **events** (seq, record_type, record_id, kind, at): application-owned history written in the same transaction.  
Public information: certification catalog, cohort dates, trainer credentials.  
Kept out of scope until handling is reviewed: exam results, employer billing, participant identity.  
Exam results and certifications are personal records; only cohort logistics and materials are modeled.  
Technical basis verified on Laravel: an optimistic version check and an event row written in the same transaction, a stale update rejected, and a history query over the application-owned events (history=2 conflict=rejected).

## Representative Queries
- Professional training: event registration using Laravel  
- Where can I host Professional training: Event registration built with Laravel?  
- I need a genuinely specialized event registration workflow covering course cohorts, enrollment events and learning-resource access.

## Resource Requirements
- primitive:compute  
- primitive:postgres  
- primitive:s3-compatible-object-storage

## Infrastructure Requirements
1. **Compute**  
   - Status: Verified  
   - Summary: Apps run in isolated x86_64 Firecracker microVMs that auto-pause when idle and wake on request; sizes are the priced VM sizes.
2. **Postgres**  
   - Status: Verified  
   - Summary: Managed PostgreSQL 16 runs in its own microVM and is auto-provisioned when an app needs a database and no DATABASE_URL is supplied.
3. **S3-compatible object storage**  
   - Status: Verified  
   - Summary: Buckets are S3-compatible with issued credentials; PutObject and GetObject are verified by canary. Other S3 operations are not verified.

## Prerequisites
- A Laravel project (composer install --no-dev from composer.lock, then FrankenPHP serving public/ (php-server with the index.php fallback) reading PORT on the php-8.5 template)
- A PostgreSQL driver reading DATABASE_URL (auto-provisioned when omitted)
- Bucket credentials from `ample bucket create` passed as encrypted S3_* environment variables
- A review of which professional training data classes may be handled at all; this blueprint models public information only

## Workflow Steps
1. **Model the professional training domain**  
   Create the tables course_groups, memberships, sessions, materials, events. Certification cohorts live in course_groups; keep the sensitive classes (exam results, employer billing, participant identity) out of this schema.
2. **Workflow step 1**  
   Model sessions with capacity and registrations with status.
3. **Workflow step 2**  
   Register transactionally with a capacity check and an event per registration.
4. **Workflow step 3**  
   Reject stale concurrent updates.
5. **Workflow step 4**  
   Deploy and verify history and conflict handling.
6. **Deploy**  
   Run the synchronous deploy once and read the result. Re-running with no change is a no-op.
7. **Verify**  
   Run the pattern self-test(s) from the example (/p/transactional-workflows) and your own acceptance checks for the professional training workflow.

## Success Checks
1. **App responds on its public URL**  
   - Kind: http_get  
   - Path: /  
   - Expect: ample canary laravel patterns  
2. **Transactional-workflows self-test from the example**  
   - Kind: http_get  
   - Path: /p/transactional-workflows  
   - Expect: see the pattern fixture checks

## Limitations
- The technical basis (transactional workflows on Laravel) was verified with the pattern fixture; the professional training schema and workflow are an original design for this blueprint and were not executed as a separate application.
- No health, financial, privacy or other compliance claim is made. Exam results and certifications are personal records; only cohort logistics and materials are modeled.
- Verified on the php-8.5 template at s-1vcpu-1gb; region, request-duration limits and other sizes are unknown or unverified.
- Managed PostgreSQL 16 only; extensions, connection limits and backup or restore procedures are not verified.
- PutObject and GetObject with path-style addressing are verified; other S3 operations and CDN cache rules are not.

## Cost Estimate
- **Currency**: USD  
- **Monthly Amount**: 10.0  
- **Basis**: size prices from pricing.toml (loaded by the API) at build revision 1ac5595375130d45290090e82ed0f554ccd45405-dirty  
   - Components:  
     - App server: size s-1vcpu-1gb, monthly amount: 5.0  
     - Managed PostgreSQL database: size s-1vcpu-1gb, monthly amount: 5.0  
- **Note**: Always-on monthly price of the tested sizes; apps and databases auto-pause when idle. Buckets are allocation-priced per quota and not included.
