---

3) Assumptions Made

1. Email delivery in development: verification is valid if token links are logged to server console (real SMTP not required yet).
2. Scoring model:
   • Module score normalized by answered questions only (selected weight / max possible for answered questions).
   • Overall score computed as equal-weight average across modules.
3. Recommendation model:
   • Primary recommendations come from low-scoring modules (score < 70) with answered questions.
   • Fallback to global (moduleId = null) recommendations if no module-targeted suggestions apply.
4. Onboarding gating:
   • Users must be authenticated and onboarded to access diagnostic/results/dashboard/recommendations/manual.
5. Data availability:
   • Seed data provides required baseline modules/questions/options/manual/recommendations.

---

4) How to Modify Logic / Implement New Specs

A) Change scoring formula

Primary files:

• src/lib/scoring-core.ts
• src/lib/scoring.ts

What to change:

• Update computeAssessmentSnapshot(...) for new formulas (weighted modules, penalties, thresholds, etc.)
• Keep DB persistence in recomputeAssessmentResults(...) synchronized with new output fields

B) Change low-score threshold or recommendation strategy

Primary file:

• src/lib/recommendations.ts

What to change:

• Modify filter condition (moduleScore.score < 70)
• Adjust ranking/prioritization and number of recommendations per module
• Add role/industry/context-aware filtering if needed

C) Add onboarding fields

Primary files:

• prisma/schema.prisma (Organization model)
• src/components/app/onboarding-wizard.tsx
• src/app/api/onboarding/route.ts

What to change:

• Add DB columns + migrate
• Add step inputs/state
• Persist and validate in API route

D) Add or modify diagnostic modules/questions/options

Primary file:

• prisma/seed.mjs

What to change:

• Add new module/question/option seed definitions (key values must be unique)
• Rerun migrate/seed

E) Swap verification transport to real email provider

Primary files:

• src/lib/auth/verification.ts
• src/app/api/auth/register/route.ts
• src/app/api/auth/login/route.ts
• src/app/api/auth/resend/route.ts

What to change:

• Keep token generation/consumption as-is
• Replace console logging with provider API call (SES/SendGrid/Postmark)

F) Customize dashboard charts and result blocks

Primary files:

• src/components/app/dashboard-view.tsx
• src/components/app/module-bars-card.tsx
• src/components/app/radar-chart-card.tsx
• src/app/results/page.tsx

What to change:

• Adjust chart labels, colors, ranges, and data mapping
• Add additional cards/insights from AssessmentResult or response-level analytics

G) Session hardening

Primary files:

• src/lib/auth/session-token.ts
• src/lib/auth/session.ts
• src/lib/auth/constants.ts

What to change:

• Rotate SESSION_SECRET
• Add token versioning/invalidations
• Add shorter TTL + refresh logic

---

5) Full Diagnosis vs Original Plan (and Fixes Applied)

Summary

The implementation now satisfies all required Phase 1-7 deliverables. The original gap found during this diagnosis was Phase 8 hardening depth (loading/error/test baseline), which has now been addressed.

Detailed checklist

• Phase 1 scaffold + UI kit + static route shell: Done
• Phase 2 schema + seed + DB viewer: Done
• Phase 3 real auth + verify + session + logout: Done
• Phase 4 onboarding wizard + persistence + redirect: Done
• Phase 5 diagnostic autosave + resume + progress: Done
• Phase 6 scoring persistence + results + dashboard charts: Done
• Phase 7 recommendations from low scores + manual/faq from DB + report placeholder: Done
• Phase 8 required polish subset:
  • consistency baseline: Done
  • loading/empty/error states: Done
  • validation/friendly errors baseline: Done
  • optional tests: Done (added baseline unit tests)

Differences discovered and fixed during this pass

1. No baseline automated tests existed -> Added Vitest + 5 unit tests:
   • src/lib/__tests__/scoring-core.test.ts
   • src/lib/__tests__/session-token.test.ts
2. No global loading/error route states -> Added:
   • src/app/loading.tsx
   • src/app/error.tsx
3. Residual mock file not used -> Removed:
   • src/lib/mock-data.ts

6) Runbook

From /var/opt/assessment-app:

1. Install deps:
   • npm install
2. Generate Prisma client:
   • npm run prisma:generate
3. Run migration(s):
   • npm run prisma:migrate -- --name init
4. Seed data:
   • npm run prisma:seed
5. Start app:
   • npm run dev
6. Quality checks:
   • npm test
   • npm run lint
   • npm run build

---

7) External Dependencies / Pending Inputs

• A working Postgres connection string is required in .env:
  • DATABASE_URL=...
• Session secret should be set to a secure value in non-dev:
  • SESSION_SECRET=...
• Email verification currently logs links in server console; production email delivery is not wired yet.

---

8) Suggested Next Implementation Targets

1. Add integration tests for register/login/verify and diagnostic autosave flow.
2. Add role-based access controls (admin/viewer) for organization scope.
3. Add report generation endpoint (PDF) behind the current placeholder button.
4. Add analytics/versioned scoring snapshots to compare improvements over time.
