# Context

Sprint 3 has been officially closed.

Pilot development has begun.

Future roadmap:

# Files in Scope

Review only:

* GuestController.php
* GuestService.php
* GuestModel.php
* GuestValidator.php
* GuestImporter.php
* routes.php
* import.php
* import_result.php

---

# Review Objectives

Review the Guest architecture against the future Pilot roadmap.

Do NOT review coding style.

Review long-term architecture.

---

# Review Area 1

Guest Identity

Current implementation uses:

guest_code

Review whether this should instead become:

guest_token

Consider:

* Personal URL
* QR Code
* RSVP
* Wish
* Check-In
* Public APIs

Recommend the most future-proof naming.

---

# Review Area 2

Guest Data Model

Current implementation stores:

Category

Seat Number

Address

inside:

notes

Review whether these attributes should become dedicated columns instead.

Consider future:

* Seating
* VIP
* Reports
* QR Check-In
* Printing
* Analytics

---

# Review Area 3

Guest Token

Review whether the generated token is suitable as the permanent public identifier.

Consider:

* URL safety
* Randomness
* Collision resistance
* Token length
* Public exposure

Recommend improvements if necessary.

---

# Review Area 4

Future Compatibility

Review compatibility with:

* Personal Invitation URL
* WhatsApp Share
* RSVP
* Wish
* QR Code
* QR Check-In
* Attendance Dashboard

Identify any architectural blockers.

---

# Review Area 5

Workspace Isolation

Verify:

* every guest belongs to one workspace
* no cross-workspace lookup
* no public identifier leaks internal database IDs

---

# Review Area 6

Maintainability

Review:

* scalability
* readability
* future extensibility

---

# Output
