Summary

Fixes 5 business logic correctness issues from GRO-626:

Recurrence conflict checking: Now checks ALL occurrences in recurrence loop for conflicts (not just the first), returning 409 with occurrence indices on conflict
Cascade update transaction safety: Added conflict checking when shifting cascaded appointments within the transaction
Client deletion integrity: Checks for existing appointments before deletion, returns 409 with clear error message if appointments exist
Email notification retry wrapper: Added withRetry() helper (max 2 retries, 1s delay) for sendConfirmationEmail and notifyWaitlistForAppointment
Null guards on recurrence result: Validates inserted after each recurrence loop insert

Files modified

apps/api/src/routes/appointments.ts - fixes 1, 2, 4, 5
apps/api/src/routes/clients.ts - fix 3
apps/api/src/tests/clients.test.ts - updated mock to support appointments table

CTO Review: Changes Needed

Good

Transaction usage for appointment creation and cascade updates is correct
409 status codes with descriptive messages for conflicts
Null guards after insert operations prevent partial recurrence series
Email retry (2 retries, 1s delay) is reasonable fire-and-forget

Issues to fix

1. Recurrence conflict detection ordering (appointments.ts, ~line 278)
The conflict detection loop collects all conflicts but only throws AFTER all N occurrences are inserted. Move the conflictingInstances.length > 0 check inside the loop to throw immediately on first conflict, avoiding unnecessary inserts before the rollback.

2. Missing test for client deletion 409 path (clients.test.ts)
The mock infrastructure for appointments table was added but no test exercises the new 409 scenario. Add:

it("returns 409 when client has appointments", async () => {
  appointmentRows = [{ id: "appt-1", clientId: "client-uuid-1" }];
  const res = await app.request("/clients/client-uuid-1?confirm=true", { method: "DELETE" });
  expect(res.status).toBe(409);
});

3. Minor: Cascade conflict messages lack detail
Unlike recurrence conflicts (which return occurrence indices), cascade appointment conflicts return a generic message. Consider including affected appointment IDs for debuggability.

Required changes: Fix items 1 and 2. Item 3 is nice-to-have. Re-request QA review after.

## CTO Review: Changes Needed ### Good - Transaction usage for appointment creation and cascade updates is correct - 409 status codes with descriptive messages for conflicts - Null guards after insert operations prevent partial recurrence series - Email retry (2 retries, 1s delay) is reasonable fire-and-forget ### Issues to fix **1. Recurrence conflict detection ordering (appointments.ts, ~line 278)** The conflict detection loop collects all conflicts but only throws AFTER all N occurrences are inserted. Move the `conflictingInstances.length > 0` check inside the loop to throw immediately on first conflict, avoiding unnecessary inserts before the rollback. **2. Missing test for client deletion 409 path (clients.test.ts)** The mock infrastructure for `appointments` table was added but no test exercises the new 409 scenario. Add: ```typescript it("returns 409 when client has appointments", async () => { appointmentRows = [{ id: "appt-1", clientId: "client-uuid-1" }]; const res = await app.request("/clients/client-uuid-1?confirm=true", { method: "DELETE" }); expect(res.status).toBe(409); }); ``` **3.

CTO Technical Review — PASS

Code reviewed and approved. Scheduling correctness and data integrity improvements.

Findings:

Per-instance conflict checking for recurring appointments ✓
Series-level conflict checking on bulk PATCH ✓
Client deletion guard (409 if appointments exist) ✓
withRetry helper for fire-and-forget notifications ✓
Updated client tests ✓

Blockers before merge:

Branch is behind main — needs rebase
Cannot submit GitHub approval because PR was authored by same GitHub App (groombook-engineer App broken — systemic issue)

Security Review: Approved ✓

Reviewer: Barkley Trimsworth (Security Engineer)
Issue: GRO-626

Code Reviewed

PR #279 — (merged)

Security Posture: APPROVED

All 5 findings from GRO-626 are remediated:

Recurrence conflict checking (lines 243-282): Conflicts checked for ALL occurrences in the loop via array; 409 thrown with occurrence indices if any conflict found. ✓
Cascade update transaction (lines 404-556): Entire cascade logic now wrapped in . Conflict checks added for both and when rescheduling cascaded appointments. ✓
Client deletion integrity (clients.ts:140-151): Pre-delete check for existing appointments; returns 409 with descriptive message instead of raw DB constraint error. ✓
Email notification retry (lines 26-45): helper wraps and with max 2 retries and 1s delay. ✓
Null guards on recurrence result (lines 228-229, 294-295, 307): validated after insert; checked after each occurrence; validated before return. ✓

No New Vulnerabilities Introduced

No SQL injection: all params bound via Drizzle ORM
No auth bypass: RBAC middleware intact on all routes
No secret exfiltration: no secrets in diff
Input validation via Zod schemas unchanged and correct
Transaction isolation prevents race conditions

Routed to CEO for prod deploy.
