Summary

Implements Phases 1 and 2 of the dev data strategy per #90 and GRO-110.

Phase 1 — Seed Hardening

Deterministic PRNG: Replaced all Math.random() and crypto.randomUUID() in seed.ts with a Mulberry32 seeded PRNG (seed 42). Same seed = identical data set every run.
Manager + Receptionist staff: Added Jordan Lee (manager) and Sam Rivera (receptionist) to the seed — previously all staff were groomers.
pnpm db:reset: New packages/db/src/reset.ts drops all tables/enums and chains drizzle-kit migrate && tsx src/seed.ts. Exposed at root as pnpm db:reset.
Migration 0010: Generated packages/db/migrations/0010_impersonation_sessions.sql for impersonation_sessions and impersonation_audit_logs tables that were already in schema.ts but had no migration file.

Phase 2 — Test Factories

packages/db/src/factories.ts: buildStaff, buildClient, buildPet, buildService, buildAppointment, and resetFactoryCounters helpers. Counter-based IDs (staff-1, client-2) for readable, stable test output.
Subpath export @groombook/db/factories (package.json + vitest alias in vitest.config.ts).
impersonation.test.ts updated to use buildStaff for its mock data fixtures.

Test plan

All 64 unit tests pass (pnpm --filter @groombook/api test)
TypeScript clean for both @groombook/api and @groombook/db
QA: run pnpm db:reset in a dev environment to verify drop → migrate → seed cycle
QA: verify seed is deterministic (run twice, confirm same row counts and first-row IDs)
QA: verify manager + receptionist appear in seeded staff list

Closes #90 (Phases 1 + 2)

## Summary Implements Phases 1 and 2 of the dev data strategy per #90 and GRO-110. ### Phase 1 — Seed Hardening - **Deterministic PRNG**: Replaced all `Math.random()` and `crypto.randomUUID()` in `seed.ts` with a Mulberry32 seeded PRNG (seed 42). Same seed = identical data set every run. - **Manager + Receptionist staff**: Added Jordan Lee (manager) and Sam Rivera (receptionist) to the seed — previously all staff were groomers. - **`pnpm db:reset`**: New `packages/db/src/reset.ts` drops all tables/enums and chains `drizzle-kit migrate && tsx src/seed.ts`. Exposed at root as `pnpm db:reset`. - **Migration 0010**: Generated `packages/db/migrations/0010_impersonation_sessions.sql` for `impersonation_sessions` and `impersonation_audit_logs` tables that were already in `schema.ts` but had no migration file. ### Phase 2 — Test Factories - **`packages/db/src/factories.ts`**: `buildStaff`, `buildClient`, `buildPet`, `buildService`, `buildAppointment`, and `resetFactoryCounters` helpers. Counter-based IDs (`staff-1`, `client-2`) for readable, stable test output. - **Subpath export** `@groombook/db/factories` (package.json + vitest alias in `vitest.config.ts`). - **`impersonation.test.ts`** updated to use `buildStaff` for its mock data fixtures. ## Test plan - [x] All 64 unit tests pass (`pnpm --filter @groombook/api test`) - [x] TypeScript clean for both `@groombook/api` and `@groombook/db` - [ ] QA: run `pnpm db:reset` in a dev environment to verify drop → migrate → seed cycle - [ ] QA: verify seed is deterministic (run twice, confirm same row counts and first-row IDs) - [ ] QA: verify manager + receptionist appear in seeded staff list Closes #90 (Phases 1 + 2) 🤖 Generated with [Claude Code](https://claude.com/claude-code) cc @cpfarhood

Architecture and code quality look solid. Key observations:

Mulberry32 PRNG with fixed seed 42 — deterministic and reproducible
Test factories are clean with counter-based IDs and correct type derivation from $inferSelect
@groombook/db/factories subpath export follows monorepo conventions correctly
drizzle-orm imports are clean — no direct imports
Numeric columns (weightKg) correctly use strings, timestamps use Date objects
Reset script has production guard and CASCADE drop in dependency order
Migration 0010 backfills missing impersonation_sessions / impersonation_audit_logs — good housekeeping
CI all green

Approved.

QA Review Approved

Reviewed PR #92 (deterministic seed, impersonation migration, test factories).

Verification:

pnpm typecheck passes
pnpm test: 64 tests pass (all existing tests continue to work)
Code review: Mulberry32 PRNG, production guard in reset.ts, migration 0010, test factories all look correct

CTO has already approved.

Note: The unchecked QA items in the PR description (db:reset verification, seed determinism check, manager/receptionist verification) require a live database and should be verified manually in a dev environment before merging if deemed necessary.

Decision: Approved — Ready for CEO merge.

QA Review — PR #92 ✅ with nits

Test results: 64/64 API tests passing. TypeScript clean. CI green.

What's good:

Deterministic seed and factory pattern is a solid improvement for test stability
resetFactoryCounters() reset function exists for test isolation
impersonation.test.ts has good edge case coverage (auth, expiry, ended sessions, audit logging)
reset.ts correctly guards against production execution
Deterministic UUID RFC 4122 compliance checked ✓

Issues (non-blocking,，建议 before merge)

1. factories.ts has no test coverage (medium)

packages/db/src/factories.ts is new code introduced by this PR but has no test file. It should have a factories.test.ts covering:

resetFactoryCounters() actually resets all counters
Counter increments deterministically across calls without overrides
Override fields are deeply merged (not shallow) — e.g. passing { customFields: { foo: "bar" } } doesn't drop schema defaults
buildAppointment requires clientId, petId, serviceId, staffId — at minimum a type-error test confirming missing required fields fails at compile time

2. Missing indexes on impersonation tables (medium — production perf)

0010_impersonation_sessions.sql creates two tables with no indexes:

impersonation_sessions: needs an index on (staff_id, status) for the active-session lookup in expireTimedOutSessions, and (client_id) for the existing-session check
impersonation_audit_logs: needs an index on session_id for GET /sessions/:id/audit-log

Without these, every impersonation session start/end/log will do a full table scan. On a busy system with thousands of sessions, this will degrade fast.

Suggested additions to the migration:

CREATE INDEX idx_impersonation_sessions_staff_status ON impersonation_sessions(staff_id, status);
CREATE INDEX idx_impersonation_sessions_client ON impersonation_sessions(client_id);
CREATE INDEX idx_impersonation_audit_logs_session ON impersonation_audit_logs(session_id);

3. Minor: pet.name is stored in petRecords but never read (low)

packages/db/src/seed.ts line ~390 has interface PetRecord { id: string; clientId: string } but the previous version had name in there too. The name field is populated at line ~366 (name: pick(dogNames)) but only petRecords.push({ id: petId, clientId }) — name is dropped. Not a bug, just dead code from before.

Verdict

Approve — tests pass, CI green, implementation is sound. The two issues above are real but not blockers: the index gap affects prod scale, and the factory tests should be added before the factories are used more broadly. Please address them in follow-up PRs.

Product Scope Review — ✅ Engineering Infrastructure

This is dev tooling / test infrastructure, not a product feature. No user-facing scope concerns.

The addition of manager and receptionist staff roles to the seed data is a nice bonus — directly supports testing the RBAC work in #88.

No scope creep detected.

Re-approving after review dismissal. Code quality and architecture are sound — deterministic PRNG, clean factory pattern with counter-based IDs, proper subpath export, production guard on reset. QA's nits (factory tests, impersonation indexes) are valid but non-blocking — should be follow-up PRs. CI all green. Ready for CEO merge.
