2. Feature Completeness Audit

2.1 Fully Implemented (Phase 1 Complete)

Feature	Backend	Frontend	Database	Notes
Project management	2 routes	Dashboard	projects	Multi-project switcher in sidebar
Contact management	5 routes	ContactsPage	contacts	CRUD + CSV import + soft delete
Interview management	5 routes	InterviewsPage	interviews	CRUD + conduct flow + soft delete
Interview conduct	3 routes	InterviewConductPage	responses, dimension_scores	Section-based scoring, real-time save
Interviewer management	4 routes	InterviewersPage	interviewers	CRUD + scheduling capacity
Hypothesis management	4 routes	HypothesesPage	hypotheses, hypothesis_validations	CRUD + validation evidence
Outreach management	4 routes	OutreachPage	outreach	Multi-channel tracking
Follow-up pipeline	3 routes	FollowUpPage	actions	Action items with status tracking
Transcript import	3 routes	TranscriptImportPage	transcripts	Paste, parse, segment
Analytics dashboard	3 routes	AnalyticsPage	(computed)	Funnel, hypothesis results, dimensions
Interview templates	3 routes	AdminPage	interview_templates	Sectioned question templates
Export (CSV/PDF)	(client)	Multiple pages	-	CSV export on contacts, interviews
Documentation pages	-	5 doc pages	-	Guide, training, framework, rubric, sheet

2.2 Backend-Only (No Frontend UI)

These features have complete backend implementations but zero frontend consumption:

Feature	Backend Routes	Service File	DB Tables	Frontend Status
Google OAuth	4 routes	google-oauth.ts (299 lines)	oauth_credentials	No /settings page, no useApi hooks
Google Calendar	5 routes	google-calendar.ts (315 lines)	calendar_events	No calendar UI, no event display
Gmail send	3 routes	google-gmail.ts (299 lines)	email_logs, email_opt_outs	No email compose UI
Email templates	5 routes	email-templates.ts (273 lines)	email_templates	No template editor page
Email campaigns	3 routes	email-queue.ts	email_campaigns	No campaign management page
Opt-out handling	1 route	(in gmail service)	email_opt_outs	No opt-out management page

Total backend-only: 21 route handlers (~950 lines of service code) with 6 database tables — all unreachable from the UI.

2.3 Critical Frontend Gap: OAuth Callback Broken

api.ts:485-486 redirects the OAuth callback to:

http://localhost:5173/settings?oauth=success
http://localhost:5173/settings?oauth=error

But App.tsx has no /settings route — the catch-all <Route path="*"> sends the user to / (Dashboard), silently discarding the OAuth result. The user would complete Google authorization but see the dashboard with no confirmation.

2.4 Missing useApi Hooks

useApi.ts (684 lines) contains hooks for all Phase 1 features but zero hooks for:

• Google OAuth (connect, disconnect, status check)
• Google Calendar (create event, check availability)
• Gmail (send email, check rate limit)
• Email Templates (CRUD, seed, render)
• Email Campaigns (create, send, queue status)

Result: Even if pages were created, they cannot call the backend without these hooks.

2.5 Missing Sidebar Navigation

Sidebar.tsx NAV_ITEMS has 10 entries. None reference email, calendar, settings, or campaigns. Users have no navigation path to any Google integration feature.

3. Usability Review

3.1 Strengths

• Consistent design system: All UI follows WPP-derived pattern with emerald accent, dark mode support, CoditectModal wrapper
• Project switcher: Multi-project support with sidebar selector
• Responsive sidebar: Flyout pattern works on mobile viewports
• Structured interview flow: Section-based conduct page with dimension scoring
• CSV import: Bulk contact import with column mapping
• Documentation built-in: 5 reference docs accessible from sidebar

3.2 Weaknesses

Issue	Severity	Location	Description
No loading states	Medium	Multiple pages	API calls don't show spinners/skeletons
No optimistic updates	Low	All CRUD forms	Forms wait for server response before updating UI
No pagination	Medium	Contacts, Interviews	All records loaded at once — will degrade with scale
No search/filter on lists	Medium	ContactsPage, InterviewsPage	Must scroll through all records
No keyboard shortcuts	Low	Global	No Cmd+K, no table navigation
No undo/redo	Low	Forms	No undo for accidental changes
No confirmation on delete	Medium	Hypotheses, Templates	Some delete handlers are hard-delete (not soft)
Dashboard is read-only	Low	DashboardPage	No drill-down into analytics data points

3.3 Accessibility

• No ARIA labels audited
• No keyboard navigation tested
• Color contrast likely acceptable (dark/light mode with high-contrast emerald accent)
• No skip navigation links
• No screen reader testing

4. Scalability Assessment

4.1 Database

Concern	Severity	Detail
SQLite single-writer	High	WAL mode helps reads, but only one write at a time. Fine for single-user pilot, blocks multi-user.
No indexes beyond PKs	Medium	Only calendar_events.google_event_id and email_opt_outs.email have explicit indexes. Contact/interview queries will slow with volume.
JSON-in-text columns	Medium	metadata, parsed_segments, variables, attendee_emails stored as JSON text. No queryable structure.
No connection pooling	Low	Single connection via getDb(). Fine for pilot.
No migrations runner	Medium	Drizzle kit generates SQL but no automated migration tool in the server startup.

Recommended indexes for pilot scale (100+ contacts, 50+ interviews):

CREATE INDEX idx_contacts_project ON contacts(project_id);
CREATE INDEX idx_contacts_status ON contacts(status);
CREATE INDEX idx_interviews_contact ON interviews(contact_id);
CREATE INDEX idx_interviews_status ON interviews(status);
CREATE INDEX idx_outreach_contact ON outreach(contact_id);
CREATE INDEX idx_email_logs_contact ON email_logs(contact_id);
CREATE INDEX idx_email_logs_campaign ON email_logs(campaign_id);
CREATE INDEX idx_hypothesis_validations_interview ON hypothesis_validations(interview_id);
CREATE INDEX idx_responses_interview ON responses(interview_id);
CREATE INDEX idx_dimension_scores_interview ON dimension_scores(interview_id);

4.2 API Server

Concern	Severity	Detail
Raw node:http	Medium	No middleware framework, no request parsing library. Each route manually parses JSON body. Works but brittle.
No request validation	High	No input validation on any endpoint. Malformed JSON or missing fields cause runtime errors.
No authentication	High	All endpoints are unauthenticated. Anyone on the network can CRUD all data.
No rate limiting (API)	Medium	Gmail rate limiting exists but no API-level rate limiting.
CORS wildcard	Medium	Access-Control-Allow-Origin: * — acceptable for localhost dev, not production.
No request logging	Low	No access log, no request timing.
Synchronous DB in async handlers	Low	Drizzle with better-sqlite3 is synchronous. Not a problem at pilot scale but blocks the event loop under load.

4.3 Frontend

Concern	Severity	Detail
No code splitting	Low	All pages bundled together. Fine at 14K LOC.
Zustand store is flat	Low	Single store with all state. Works for current feature set.
No error boundaries	Medium	Component errors crash the whole app.
No offline support	Low	No service worker, no local cache. Expected for internal tool.

customer-segmentation	Segment contacts by engagement	Prioritize interview scheduling

5.3 External Integration Opportunities

Integration	Status	Gap
Google Calendar	Backend complete	Frontend UI needed
Gmail	Backend complete	Frontend UI needed
LinkedIn	Not started	Contact enrichment from LinkedIn profiles
Calendly	Not started	Alternative to custom calendar integration
Zoom/Google Meet	Partial (Meet via Calendar)	Recording import, auto-transcription
Notion	Not started	Export interview insights to team wiki
Slack	Not started	Notifications for scheduled interviews, completed validations

6. Priority Recommendations

6.1 Critical (Before Pilot Use)

#	Item	Rationale	Effort
1	Settings page with OAuth connection UI	Google integration is complete backend-side but unusable without UI. OAuth callback redirects to nonexistent page.	~200 LOC
2	useApi hooks for Google integration	Required for any frontend to call the 21 Google endpoints	~150 LOC
3	Sidebar navigation for Settings/Email	Users need to discover and navigate to integration features	~20 LOC
4	Basic input validation on API	Prevent runtime crashes from malformed requests	~100 LOC

6.2 High (Before Broader Rollout)

#	Item	Rationale	Effort
5	Email compose/campaign management page	Unlock the email send + campaign features	~400 LOC
6	Calendar event display on interview records	Show scheduled events, Meet links	~100 LOC
7	Database indexes	Performance at 100+ contacts/interviews	~20 LOC SQL
8	Pagination on list pages	Contacts and interviews will grow	~100 LOC per page
9	Error boundaries	Prevent full-app crashes from component errors	~50 LOC

6.3 Medium (Phase 2)

#	Item	Rationale	Effort
10	Authentication/authorization	Required for multi-user deployment	High
11	PostgreSQL migration	Multi-user concurrency, proper indexes	Medium
12	Multi-tenant RLS	Per-venture data isolation	High
13	Test suite	Zero tests currently — need at least service layer tests	Medium
14	SDD update	Document is stale (missing 6 tables, 21 routes, 5 services)	Low
15	Request logging and monitoring	Operational visibility	Low

ui/pages/ContactsPage.tsx	~350	Contact list with CSV import
ui/hooks/useApi.ts	684	All API hooks (missing Google integration)
db/seed.ts	964	Sample data seeding

7.3 Database Tables (18 total)

Original (12): projects, contacts, interviews, responses, dimension_scores, hypotheses, hypothesis_validations, interview_templates, interviewers, outreach, transcripts, actions

Added in Iteration 5 (6): oauth_credentials, calendar_events, email_logs, email_opt_outs, email_templates, email_campaigns

---

8. Conclusion

The Validation Interview Tracking System is a substantial 14,392-line application with comprehensive backend coverage across 18 database tables and 42+ API routes. The core validation workflow (contacts -> outreach -> interviews -> scoring -> hypothesis validation -> analytics) is fully functional end-to-end.

The most significant gap is the frontend-backend disconnect for Google integration — 21 API endpoints and ~950 lines of service code are fully implemented but entirely unreachable from the UI. The OAuth callback actively breaks by redirecting to a nonexistent /settings page.

For pilot readiness, the critical path is:

1. Settings page + OAuth hooks + sidebar navigation (~370 LOC)
2. Email compose page (~400 LOC)
3. Basic input validation (~100 LOC)
4. Database indexes (~20 LOC SQL)

Total effort to close critical gaps: ~890 lines of code.
