feat(api): cascade delay prevention for overrunning appointments
- New lib/cascade.ts: detect when PATCH extends endTime beyond original, query same-groomer downstream active appointments, and shift them forward by (overrunEnd + buffer − downstreamStart). Propagates through the chain until no more conflicts. - Cascade result (shifted[], flaggedForReview[], cascadeLog[]) included in the PATCH response when a shift occurs. Clients receive reschedule email notification. Out-of-business-hours shifts are flagged rather than auto-applied. - Added cascadeDelay() and cascadeOnStatusOverrun() helpers. - Cascade wired into the this_only PATCH path in appointments.ts. Tests: cascade.test.ts UAT: apps/api/UAT_PLAYBOOK.md §2 Refs: GRO-1175, GRO-1162-G Co-Authored-By: Paperclip <noreply@paperclip.ing>

# GroomBook API — UAT Playbook
|
||||
|
||||
This document captures user-acceptance test cases for GroomBook API features. Each section corresponds to a feature or bug-fix PR. Update this file when a PR changes user-facing behaviour.
|
||||
|
||||
---
|
||||
|
||||
## 1. Appointment Booking (`/api/appointments`)
|
||||
|
||||
### 1.1 Create Appointment
|
||||
- [ ] POST `/api/appointments` with valid payload → 201, appointment returned with generated id
|
||||
- [ ] Overlapping staff appointment → 409 conflict error returned
|
||||
- [ ] `endTime` before `startTime` → 422 error
|
||||
|
||||
### 1.2 Update Appointment (PATCH `/api/appointments/:id`)
|
||||
- [ ] Extending `endTime` on a `scheduled` appointment triggers cascade delay prevention if downstream appointments exist
|
||||
- [ ] Extending `endTime` returns `cascade` object in response with shifted appointments
|
||||
- [ ] Extending `endTime` sends reschedule email to each affected client
|
||||
- [ ] Appointments outside business hours after shift are flagged in `cascade.flaggedForReview` instead of auto-shifted
|
||||
- [ ] Only `scheduled` and `confirmed` downstream appointments are shifted; `in_progress`, `completed`, `cancelled` are skipped
|
||||
- [ ] Cascade stops when a downstream appointment no longer conflicts with the shifted boundary
|
||||
- [ ] Shifts are included in API response under `cascade.shifted[]`
|
||||
|
||||
### 1.3 Series (Recurring) Appointments
|
||||
- [ ] Updating one occurrence with `cascadeMode: "this_and_future"` shifts that occurrence and all future ones
|
||||
- [ ] Updating one occurrence with `cascadeMode: "all"` shifts every occurrence in the series
|
||||
|
||||
---
|
||||
|
||||
## 2. Cascade Delay Prevention
|
||||
|
||||
### 2.1 Basic Cascade
|
||||
- [ ] When a groomer's appointment overruns, the next same-groomer `scheduled` appointment shifts forward
|
||||
- [ ] Delta applied to both `startTime` and `endTime` (duration preserved)
|
||||
- [ ] Cascade propagates through multiple downstream appointments
|
||||
|
||||
### 2.2 Buffer Time
|
||||
- [ ] A configurable buffer (default 15 minutes) is added between the overrunning appointment end and the shifted start
|
||||
- [ ] Cascade respects the buffer between each consecutive pair of appointments
|
||||
|
||||
### 2.3 Business Hours Guard
|
||||
- [ ] If a proposed shift would place an appointment start or end outside business hours, it is flagged instead of shifted
|
||||
- [ ] Flagged appointments are listed in `cascade.flaggedForReview[]` with reason text
|
||||
|
||||
### 2.4 Email Notification
|
||||
- [ ] Each shifted appointment triggers a reschedule email to the client
|
||||
- [ ] Email includes original time (struck through) and new time
|
||||
- [ ] Email is skipped silently if SMTP is not configured
|
||||
|
||||
### 2.5 Status Transition Overrun
|
||||
- [ ] When an `in_progress` appointment's actual end time exceeds `endTime + bufferMinutes`, the cascade is triggered using the status transition path
|
||||
|
||||
---
|
||||
|
||||
## 3. Authentication & RBAC
|
||||
|
||||
### 3.1 Staff Authentication
|
||||
- [ ] Unauthenticated request → 401
|
||||
- [ ] Groomer role can only view/edit their own appointments → 403 for others
|
||||
- [ ] Manager role can view/edit all appointments
|
||||
|
||||
### 3.2 Client Authentication
|
||||
- [ ] Clients can access their own appointments via tokenized links
|
||||
- [ ] Tokenized confirm/cancel links work without authentication
