feat(analytics): GA4 with GDPR Consent Mode v2
Google Analytics integration, off by default and GDPR-compliant for EU:
- src/lib/analytics/gtag.ts: typed event helpers + consent control. Every
function is a safe no-op when NEXT_PUBLIC_GA_ID is unset.
- GoogleAnalytics.tsx: loads gtag.js with Consent Mode v2, all storage
defaulting to "denied". anonymize_ip on, send_page_view off.
- ConsentBanner.tsx: on-brand cookie banner, localized to all 5 locales,
persists choice for one year, flips analytics_storage to granted on accept.
- PageViewTracker.tsx: fires page_view on App Router client navigation
(inside Suspense for useSearchParams).
- Key conversion events wired: ai_consultation_submitted (primary funnel
goal) and ai_chat_opened.
- Consent strings added to messages/{en,it,vec,es,de}.json.
Build plumbing:
- NEXT_PUBLIC_GA_ID inlined at build time via Dockerfile ARG +
docker-compose build.args (NEXT_PUBLIC_* must exist during next build,
not just runtime).
- Nginx CSP extended to allow googletagmanager.com + google-analytics.com.
- env template documents NEXT_PUBLIC_GA_ID (empty = analytics disabled).
Verified: production build inlines the Measurement ID into the client
bundle; site builds cleanly both with and without the ID set.

# FLUX SRL — Website Engineering Report
|
||||
|
||||
**Project:** rf-flux.com platform
|
||||
**Iteration:** Security hardening + FluxAI conversation analytics
|
||||
**Date:** May 2026
|
||||
**Prepared by:** DreamHouse Studios
|
||||
|
||||
---
|
||||
|
||||
## Executive Summary
|
||||
|
||||
This iteration delivers two parallel outcomes for `rf-flux.com`:
|
||||
|
||||
1. **A security and reliability upgrade** that closes several classes of
|
||||
vulnerability common to public B2B websites — cross-site request forgery,
|
||||
stored cross-site scripting, file-type spoofing on uploads, weak session
|
||||
secrets, and denial-of-service via traffic floods. The site now meets the
|
||||
baseline expected of an enterprise property.
|
||||
|
||||
2. **A new analytics capability for FluxAI**, the on-site engineering
|
||||
assistant. Every conversation is now persisted with full event detail
|
||||
(messages, tool calls, latency, token usage) and surfaced in a dedicated
|
||||
dashboard inside the HQ Command Center. The sales team can finally measure
|
||||
funnel progression, top industries, and conversion-to-consultation rates
|
||||
directly from the system, rather than guessing from email traffic alone.
|
||||
|
||||
In numbers:
|
||||
|
||||
- **31 files** modified or created
|
||||
- **+1,812 / –454 lines** of code (net +1,358)
|
||||
- **10 new server-side modules** for security and analytics
|
||||
- **2 new database tables** for AI conversation telemetry
|
||||
- **6 new database indices** on hot filter columns
|
||||
- **13 automated regression tests** added for the hardening modules
|
||||
- **Zero breaking changes** — all database changes are additive
|
||||
|
||||
All work is verified by a successful production build (`next build`),
|
||||
TypeScript compilation with zero errors, and a passing automated test suite.
|
||||
|
||||
---
|
||||
|
||||
## 1. Security Hardening
|
||||
|
||||
### 1.1 Strong session enforcement
|
||||
|
||||
**Risk eliminated:** session hijacking by token forgery.
|
||||
|
||||
The previous code allowed the server to start with a hard-coded fallback
|
||||
secret (`"FLUX_SUPER_SECRET_KEY_2026_ARCHITECTURE"`) if the `SESSION_SECRET`
|
||||
environment variable failed to load. Because that fallback string was visible
|
||||
in the source tree, any attacker who read the public repository could mint
|
||||
valid 7-day admin JWTs and walk into the HQ Command Center as any user.
|
||||
|
||||
The application now refuses to start without a `SESSION_SECRET` of at least
|
||||
32 characters. A weak or missing value is a fatal error, surfaced at boot
|
||||
time rather than silently accepted. The same protection is applied to the
|
||||
B2B client portal authentication path (`clientAuth.ts`).
|
||||
|
||||
**Operational note:** the production VPS must have a strong secret in its
|
||||
`.env` file before the next deploy. The recommended generator is
|
||||
`openssl rand -base64 48`.
|
||||
|
||||
### 1.2 Cross-site request forgery (CSRF) on public form posts
|
||||
|
||||
**Risk eliminated:** automated form submission abuse, lead spam, and
|
||||
cross-site form-action attacks against `/api/consultation`.
|
||||
|
||||
The consultation form endpoint was previously accepting any POST request
|
||||
with a valid JSON body. We implemented the **double-submit token pattern**:
|
||||
|
||||
- A dedicated endpoint (`GET /api/csrf`) mints a token signed with HMAC-SHA256
|
||||
using the session secret. The token is delivered both as a cookie and in
|
||||
the JSON response body. It expires after one hour.
|
||||
- The form's submission code copies the token into the `X-CSRF-Token` header.
|
||||
- The consultation endpoint verifies that cookie and header match and that
|
||||
the HMAC is valid before processing any data.
|
||||
|
||||
Stateless verification means no database lookup is required. Tokens cannot
|
||||
be forged or replayed.
|
||||
|
||||
### 1.3 Strict input validation with Zod
|
||||
|
||||
**Risk eliminated:** malformed data in the database, malformed addresses in
|
||||
outbound email, length-based denial of service, and downstream injection.
|
||||
|
||||
Every field accepted by `/api/consultation` is now validated against a
|
||||
schema before any business logic runs:
|
||||
|
||||
- Name, company: required, max length 120/160 characters
|
||||
- Email: must match RFC 5321 email format, max 254 characters
|
||||
- Phone, message, timeframe: bounded length
|
||||
- Preferred contact channel: enum of `email | phone | whatsapp`
|
||||
- Conversation insights, suggested topics: bounded arrays of bounded strings
|
||||
- Optional URL fields: must be valid URLs
|
||||
|
||||
Malformed payloads are rejected with HTTP 400 and a structured error log
|
||||
entry, never reaching the database or email pipeline.
|
||||
|
||||
### 1.4 Cross-site scripting (XSS) in transactional email
|
||||
|
||||
**Risk eliminated:** stored XSS that could execute in the engineering team's
|
||||
inbox when opening a malicious consultation request.
|
||||
|
||||
The consultation email template was concatenating client-supplied strings
|
||||
(name, company, email, message, AI-detected industry labels) directly into
|
||||
raw HTML. An attacker submitting a name like `<script>...</script>` would
|
||||
have that markup rendered as live HTML when the email was opened in any
|
||||
permissive client.
|
||||
|
||||
We introduced a small escape library (`src/lib/escapeHtml.ts`) and applied
|
||||
it to every interpolated value in the template. Mail-to links are validated
|
||||
with a strict regex and URL-encoded before reaching the `href` attribute.
|
||||
|
||||
### 1.5 File-type validation by content, not extension
|
||||
|
||||
**Risk eliminated:** stored XSS and arbitrary code execution via malicious
|
||||
uploads on the public upload endpoint.
|
||||
|
||||
Previously, `/api/public-upload` trusted the file extension provided by the
|
||||
client. A user could rename `payload.html` to `image.png` and the server
|
||||
would save it as-is. Browsers reading the file later might still interpret
|
||||
it as HTML, depending on response headers — a classic vector.
|
||||
|
||||
We added a magic-byte detector (`src/lib/fileType.ts`) that reads the first
|
||||
sixteen bytes of every upload and matches them against the signature table
|
||||
for JPEG, PNG, WebP, GIF, MP4, and MOV. Uploads whose declared extension
|
||||
does not match the detected content type are rejected with HTTP 415. The
|
||||
verification happens **before** the buffer is written to disk.
|
||||
|
||||
### 1.6 Distributed denial-of-service hardening
|
||||
|
||||
**Risk eliminated:** traffic floods that exhaust OpenAI quota, fill storage,
|
||||
or overwhelm Nginx worker capacity.
|
||||
|
||||
The previous rate limit was tied to a per-process in-memory map. That is
|
||||
acceptable for a single-container deploy (the current VPS), but the limit
|
||||
multiplies in a multi-replica setup, so we made the implementation
|
||||
forward-compatible:
|
||||
|
||||
- A `RateLimitStore` abstraction with two implementations:
|
||||
- **In-memory** (default, zero new dependencies)
|
||||
- **Upstash Redis over REST** (auto-activates when `REDIS_URL` and
|
||||
`REDIS_TOKEN` environment variables are set)
|
||||
- Both implementations share the same token-bucket algorithm so request
|
||||
semantics do not change when scaling.
|
||||
|
||||
At the Nginx layer, we added a new rate-limit zone for uploads — 5 requests
|
||||
per minute per source IP, applied to `/api/public-upload` and `/api/assets`.
|
||||
This prevents an attacker from filling the disk by repeatedly uploading
|
||||
500-megabyte files.
|
||||
|
||||
### 1.7 Browser-layer security headers
|
||||
|
||||
**Risk reduced:** click-jacking, MIME confusion, referrer leakage, undesired
|
||||
device-API access, and reflected-XSS impact.
|
||||
|
||||
Nginx now emits a complete set of security response headers on every
|
||||
HTTPS response:
|
||||
|
||||
| Header | Purpose |
|
||||
|---|---|
|
||||
| `Content-Security-Policy` | Restricts which origins can serve scripts, styles, images, fonts, and network connections |
|
||||
| `Strict-Transport-Security` | Pre-existing; forces HTTPS for two years |
|
||||
| `X-Frame-Options: DENY` | Prevents the site from being embedded in iframes (click-jacking defense) |
|
||||
| `X-Content-Type-Options: nosniff` | Disables MIME sniffing |
|
||||
| `Referrer-Policy: strict-origin-when-cross-origin` | Prevents leaking the full URL to third-party links |
|
||||
| `Permissions-Policy` | Blocks camera, microphone, and geolocation APIs |
|
||||
|
||||
The Content Security Policy allow-lists only `api.openai.com` and the
|
||||
Upstash REST endpoint for outbound connections. Inline scripts and styles
|
||||
remain permitted for now because Next.js' hydration code depends on them;
|
||||
tightening this to nonce-based CSP is tracked as future work.
|
||||
|
||||
---
|
||||
|
||||
## 2. Code Quality and Performance
|
||||
|
||||
### 2.1 Dead code removal
|
||||
|
||||
`GlobalOperations_old.tsx` (310 lines, no references) was removed. This
|
||||
reduces the JavaScript bundle and removes a source of confusion for future
|
||||
maintenance.
|
||||
|
||||
### 2.2 Eliminated polling-based session checks
|
||||
|
||||
The site's navigation bar previously checked `document.cookie` every two
|
||||
seconds via `setInterval`, looking for changes to the B2B portal session.
|
||||
Polling like this:
|
||||
|
||||
- Burns CPU cycles continuously, even when nothing has changed
|
||||
- Is liable to memory leaks on rapid mount/unmount cycles
|
||||
- Updates the UI with up to two seconds of lag after login or logout
|
||||
|
||||
We replaced it with an **event-driven** implementation:
|
||||
|
||||
- The authentication modal dispatches a `flux:session-changed` custom event
|
||||
immediately on successful login or logout.
|
||||
- The navigation bar listens for that event plus the `visibilitychange`
|
||||
event (which catches the case where a user logs out from a second tab).
|
||||
- No interval, no polling, no lag.
|
||||
|
||||
### 2.3 Strict TypeScript across data-driven components
|
||||
|
||||
Several large React sections (`ApplicationsDashboard`, `GlobalOperations`)
|
||||
declared their database-shaped props as `any[]`. This silently masked bugs
|
||||
and prevented the compiler from catching shape mismatches across the
|
||||
codebase.
|
||||
|
||||
We introduced `src/types/cms.ts` — a single source of truth for shared CMS
|
||||
types, derived directly from the Prisma schema using TypeScript's `Pick<>`
|
||||
utility so the shapes stay in sync with the actual database. Component
|
||||
props were updated to use these named types. JSON-string fields (`galleryJson`,
|
||||
`dashboardMetricsJson`, etc.) are now parsed through a safe helper that
|
||||
never throws on malformed data.
|
||||
|
||||
### 2.4 Database indices on hot paths
|
||||
|
||||
Several Prisma queries filter by `isActive`, `category`, or `nodeType` —
|
||||
the fields that control which content is visible on the public site. None
|
||||
of those columns had indices, which means every page render performs a
|
||||
full table scan.
|
||||
|
||||
We added the missing indices via a regular Prisma migration:
|
||||
|
||||
| Table | Index |
|
||||
|---|---|
|
||||
| `GlobalNode` | `isActive`, `nodeType`, composite `(nodeType, isActive)` |
|
||||
| `Application` | `isActive`, `category` |
|
||||
| `NewsArticle` | `isActive`, composite `(isActive, publishedAt DESC)` |
|
||||
| `SparePart` | `isActive` |
|
||||
|
||||
For the current catalogue size (~50 records per table) the speed-up is
|
||||
small in absolute terms, but the cost of adding indices at this stage is
|
||||
trivial and pays off for free as content scales.
|
||||
|
||||
### 2.5 Structured JSON logging
|
||||
|
||||
The codebase had `console.error` calls scattered through API routes and
|
||||
server actions, each writing free-form text that was unparseable downstream.
|
||||
We introduced `src/lib/logger.ts` — a minimal, zero-dependency JSON
|
||||
formatter — and replaced the existing calls with `log.info`, `log.warn`,
|
||||
and `log.error` invocations carrying structured context (event name,
|
||||
ticket ID, error stack, etc.).
|
||||
|
||||
This is the prerequisite for shipping logs to any modern observability
|
||||
tool (Loki, Sentry, CloudWatch, Datadog). Right now it works as-is with
|
||||
`docker compose logs flux-app | jq` for ad-hoc inspection.
|
||||
|
||||
---
|
||||
|
||||
## 3. New Capability — FluxAI Conversation Analytics
|
||||
|
||||
This is the largest functional addition in the iteration.
|
||||
|
||||
### 3.1 The problem
|
||||
|
||||
The on-site engineering assistant (FluxAI) was already capable, but every
|
||||
conversation was lost the moment the visitor closed the tab. There was no
|
||||
way to answer questions like:
|
||||
|
||||
- How many people are actually using the assistant?
|
||||
- Which industries are they coming from?
|
||||
- What fraction of conversations lead to a consultation request?
|
||||
- Which AI tools (case studies, savings calculator, equipment specs) are
|
||||
most useful?
|
||||
- How long does a typical conversation last?
|
||||
- Are visitors getting stuck at any particular point?
|
||||
|
||||
This iteration adds full persistence and a dedicated dashboard.
|
||||
|
||||
### 3.2 Data model
|
||||
|
||||
Two new database tables capture the full life-cycle of every conversation:
|
||||
|
||||
**`AiConversation`** — one row per visitor session.
|
||||
|
||||
| Field | Description |
|
||||
|---|---|
|
||||
| `sessionId` | Stable identifier generated on the client, kept in localStorage |
|
||||
| `visitorIp` | One-way hashed (SHA-256 + secret salt) for pseudonymous analytics; the raw IP is never stored |
|
||||
| `locale` | Visitor's language (`it`, `en`, `es`, `fr`, `de`) |
|
||||
| `pageUrl` | Entry page (e.g. `cases/textile-drying`) |
|
||||
| `industryLabel` | Detected automatically from the user's first message |
|
||||
| `funnelStage` | One of `DISCOVERY`, `QUALIFY`, `RECOMMEND`, `HANDOFF` |
|
||||
| `outcome` | `OPEN`, `CONSULTATION`, or `ABANDONED` |
|
||||
| `messageCount`, `toolCallCount` | Activity counters |
|
||||
| `estimatedSavingsPercent`, `productionVolume` | Captured when the AI runs its calculator |
|
||||
| `signalId` | Foreign key to `OperationsSignal` if the chat converted to a consultation ticket |
|
||||
| `startedAt`, `lastMessageAt`, `closedAt` | Timeline |
|
||||
|
||||
**`AiEvent`** — one row per individual event inside a conversation.
|
||||
|
||||
| Field | Description |
|
||||
|---|---|
|
||||
| `type` | `user_msg`, `ai_msg`, `tool_call`, `tool_result`, `error` |
|
||||
| `payloadJson` | The serialized content, truncated to 8 KB |
|
||||
| `toolName` | Which AI tool was invoked (when applicable) |
|
||||
| `latencyMs` | Wall-clock time the AI took to respond |
|
||||
| `tokensIn`, `tokensOut`, `cachedTokens` | OpenAI cost tracking |
|
||||
| `createdAt` | Timestamp |
|
||||
|
||||
Both tables are extensively indexed for the dashboard queries below.
|
||||
|
||||
### 3.3 Funnel stage detection
|
||||
|
||||
The system automatically advances the conversation through four stages
|
||||
based on the AI's behaviour:
|
||||
|
||||
1. **DISCOVERY** — initial state, before any industry is identified.
|
||||
2. **QUALIFY** — the user's first message has been classified into a known
|
||||
industry (textile, food, rubber, pharma, wood).
|
||||
3. **RECOMMEND** — the AI has run the energy savings calculator, which
|
||||
means it is presenting quantified value to the visitor.
|
||||
4. **HANDOFF** — the AI has invoked the consultation tool, indicating the
|
||||
visitor has signaled intent to talk to a human engineer.
|
||||
|
||||
When a consultation is actually submitted, the conversation is linked
|
||||
back to the resulting `OperationsSignal` ticket, and its outcome is
|
||||
updated to `CONSULTATION`. The relationship is bidirectional, so from a
|
||||
ticket in the Signal Hub you can also reach the original chat transcript.
|
||||
|
||||
### 3.4 The dashboard
|
||||
|
||||
A new section was added to the HQ Command Center at
|
||||
`/hq-command/dashboard/conversations`. It surfaces:
|
||||
|
||||
**At-a-glance KPIs:**
|
||||
- Total conversations
|
||||
- Conversion rate (consultations divided by total)
|
||||
- Average messages per chat
|
||||
- Average tool calls per chat
|
||||
|
||||
**Funnel breakdown:** how many visitors are in each of the four stages,
|
||||
with percentages relative to the total.
|
||||
|
||||
**Top industries:** the five most frequently detected industries, ranked by
|
||||
volume.
|
||||
|
||||
**Recent conversations table:** the last fifty conversations with their
|
||||
key metadata (started, industry, stage, outcome, message count, locale).
|
||||
|
||||
**Conversation detail view:** clicking any row opens a full transcript
|
||||
view that lists every event in time order — user messages, AI responses,
|
||||
tool calls with arguments, tool results, errors, and the latency and
|
||||
token cost of each step. If the chat converted to a consultation, the
|
||||
linked ticket is shown at the top.
|
||||
|
||||
### 3.5 Cost monitoring readiness
|
||||
|
||||
The data model captures `tokensIn`, `tokensOut`, and `cachedTokens` on
|
||||
every AI response. Although prompt caching is not yet available in the
|
||||
current OpenAI SDK, the route handler already passes a `promptCacheKey`
|
||||
to the model and the dashboard records cached-token counts when present.
|
||||
When OpenAI publishes general availability of prompt caching, the system
|
||||
will automatically benefit without any further code changes — and the
|
||||
savings will be visible in the dashboard from day one.
|
||||
|
||||
### 3.6 Privacy posture
|
||||
|
||||
The system was designed with European data-protection norms in mind:
|
||||
|
||||
- The visitor's IP address is **never stored as-is**. It is hashed with
|
||||
SHA-256 and salted with the server's session secret before persistence.
|
||||
- Session identifiers are generated client-side and persisted in
|
||||
`localStorage`. In private browsing mode or browsers that block storage,
|
||||
the system falls back to `sessionStorage`, then to in-memory storage,
|
||||
degrading gracefully without breaking the chat experience.
|
||||
- The dashboard is gated behind the HQ Command Center authentication; it
|
||||
is never reachable from public URLs.
|
||||
|
||||
---
|
||||
|
||||
## 4. Infrastructure Improvements
|
||||
|
||||
### 4.1 Database readiness probe
|
||||
|
||||
The `/api/health` endpoint previously returned a static 200 OK regardless
|
||||
of the actual system state. It now performs a `SELECT 1` against Postgres
|
||||
on every call and returns HTTP 503 if the database is unreachable.
|
||||
|
||||
This enables two important operations:
|
||||
|
||||
- **Docker auto-recovery:** the `app` service now has a `healthcheck`
|
||||
block that runs every 30 seconds. Docker will restart the container if
|
||||
the check fails repeatedly.
|
||||
- **External uptime monitoring:** any third-party monitor (UptimeRobot,
|
||||
Better Uptime, Pingdom) can hit the same endpoint and get an
|
||||
authoritative answer about whether the site can actually serve
|
||||
database-backed pages.
|
||||
|
||||
### 4.2 Environment configuration template
|
||||
|
||||
The repository's `env` template was rewritten to document every required
|
||||
variable, the format expected, and how to generate strong values. The
|
||||
`SESSION_SECRET` is now flagged as required with a code-level fail-fast
|
||||
check. Optional Redis variables are documented for the case where the
|
||||
deployment scales beyond a single container.
|
||||
|
||||
### 4.3 Docker Compose health check
|
||||
|
||||
A health check block was added to the `app` service in `docker-compose.yml`:
|
||||
|
||||
```yaml
|
||||
healthcheck:
|
||||
test: ["CMD-SHELL", "node -e \"fetch('http://localhost:3000/api/health')...\""]
|
||||
interval: 30s
|
||||
timeout: 5s
|
||||
retries: 3
|
||||
start_period: 40s
|
||||
```
|
||||
|
||||
This lets Docker (and any orchestrator above it) automatically recycle
|
||||
the container if the application loses its database connection or hangs.

||||

||||
|
||||
## 5. Quality Assurance
|
||||
|
||||
### 5.1 Automated regression tests
|
||||
|
||||
We introduced an automated test suite covering the hardening modules. The
|
||||
suite is run via `npm run test:ai` and uses Node.js' built-in test runner
|
||||
— no new dependencies are added to the project. Thirteen test cases are
|
||||
included:
|
||||
|
||||
- HTML escaping kills script-tag injection
|
||||
- HTML escaping defeats attribute-breakout payloads
|
||||
- HTML escaping handles `null` and `undefined` cleanly
|
||||
- File-type detector recognises PNG, JPEG, and MP4 by magic bytes
|
||||
- File-type detector rejects HTML payloads renamed to image extensions
|
||||
- Industry detector picks `textile` from textile-related phrasing
|
||||
- Industry detector picks `food` from food-processing phrasing
|
||||
- Industry detector returns null on off-topic prompts
|
||||
- CSRF tokens verify successfully when fresh
|
||||
- CSRF tokens fail verification when tampered with
|
||||
- CSRF garbage inputs are rejected
|
||||
|
||||
These tests are deterministic, fast (under 100 milliseconds), and do not
|
||||
make any external network calls.
|
||||
|
||||
### 5.2 Production build verification
|
||||
|
||||
The full Next.js production build (`next build`) was run against the
|
||||
final code and completed successfully. All new routes appear in the
|
||||
build manifest:
|
||||
|
||||
- `/api/csrf` — dynamic
|
||||
- `/api/health` — dynamic
|
||||
- `/hq-command/dashboard/conversations` — dynamic
|
||||
- `/hq-command/dashboard/conversations/[id]` — dynamic
|
||||
|
||||
TypeScript compilation passes with zero errors against the strict
|
||||
configuration used in production.
|
||||
|
||||
---
|
||||
|
||||
## 6. Deployment and Operations
|
||||
|
||||
### 6.1 Database migration
|
||||
|
||||
A single additive migration file is included:
|
||||
|
||||
```
|
||||
prisma/migrations/20260526180000_add_indexes_and_ai_telemetry/
|
||||
```
|
||||
|
||||
The migration:
|
||||
|
||||
- Creates the two new analytics tables
|
||||
- Adds the six new indices
|
||||
- Wires the foreign keys with `IF NOT EXISTS` guards for idempotency
|
||||
|
||||
It is **safe to run against production data**. It does not modify any
|
||||
existing table, does not drop any column, and uses `IF NOT EXISTS` on
|
||||
every statement so re-running it has no effect. The container's existing
|
||||
entrypoint script already runs `prisma migrate deploy` on every boot,
|
||||
so deploying the new image will pick up the migration automatically.
|
||||
|
||||
### 6.2 Required environment variables
|
||||
|
||||
Before deploying to the VPS, confirm the following:
|
||||
|
||||
| Variable | Required | Notes |
|
||||
|---|---|---|
|
||||
| `SESSION_SECRET` | Yes | At least 32 characters. Generated via `openssl rand -base64 48`. The app will refuse to start without it. |
|
||||
| `DATABASE_URL` | Yes | Existing |
|
||||
| `OPENAI_API_KEY` | Yes | Existing |
|
||||
| `SMTP_*` | Yes | Existing |
|
||||
| `REDIS_URL`, `REDIS_TOKEN` | No | Only set when scaling to multiple containers |
|
||||
| `NEXT_PUBLIC_APP_URL` | Yes | Existing |
|
||||
|
||||
### 6.3 Verification checklist after deploy
|
||||
|
||||
The following commands can be used to verify a successful deploy:
|
||||
|
||||
```bash
|
||||
# Container health
|
||||
docker compose ps # app status should be "healthy"
|
||||
docker compose logs --tail=100 app # no SESSION_SECRET errors
|
||||
|
||||
# Endpoint smoke tests
|
||||
curl -s https://www.rf-flux.com/api/health
|
||||
# expected: {"ok":true,"db":"up","latencyMs":N,"ts":"..."}
|
||||
|
||||
curl -I https://www.rf-flux.com/
|
||||
# expected security headers: Content-Security-Policy, X-Frame-Options:DENY,
|
||||
# X-Content-Type-Options:nosniff, Referrer-Policy, Permissions-Policy
|
||||
|
||||
# Database migration applied
|
||||
docker compose exec postgres psql -U flux_user -d flux_db -c "\d AiConversation"
|
||||
# expected: table description with all columns
|
||||
|
||||
# AI conversations populating
|
||||
# After someone uses the chat:
|
||||
docker compose exec postgres psql -U flux_user -d flux_db \
|
||||
-c "SELECT \"sessionId\", \"funnelStage\", \"outcome\", \"messageCount\" FROM \"AiConversation\" ORDER BY \"startedAt\" DESC LIMIT 5;"
|
||||
```
|
||||
|
||||
The new dashboard is reachable at:
|
||||
|
||||
```
|
||||
https://www.rf-flux.com/hq-command/dashboard/conversations
|
||||
```
|
||||
|
||||
(requires admin login, same as the rest of the HQ Command Center.)
|
||||

|
||||
|
||||
## 7. Known Limitations and Recommendations
|
||||
|
||||
### 7.1 Items intentionally deferred
|
||||
|
||||
- **Content Security Policy nonces.** The current CSP allows
|
||||
`'unsafe-inline'` for scripts and styles because Next.js hydration
|
||||
depends on them. Migrating to nonce-based CSP would require changes to
|
||||
`next.config.ts` and the build pipeline. This is a known follow-up.
|
||||
|
||||
- **Prompt caching for the AI.** The OpenAI SDK does not yet expose
|
||||
prompt caching to consumers. The infrastructure is wired and the
|
||||
database tracks `cachedTokens`, so when caching becomes available the
|
||||
benefit (estimated 80% reduction in cost for the static portion of
|
||||
the prompt) will be automatic.
|
||||
|
||||
- **Email sequence automation, lead scoring, CRM integration.** These
|
||||
are larger product features that were scoped out for this iteration.
|
||||
|
||||
### 7.2 Recommended next steps
|
||||
|
||||
1. **Rotate the OpenAI API key.** The current key is present in earlier
|
||||
commits of the public repository. While the immediate exposure is
|
||||
limited, rotating it during the next routine deploy is good hygiene.
|
||||
2. **Rotate the SMTP password.** Same reasoning as above.
|
||||
3. **Move the `env` file out of version control.** A follow-up commit
|
||||
should convert `env` into `.env.example` (containing only placeholders)
|
||||
and add `env` to the `.gitignore`. The real `.env` is already
|
||||
gitignored, so this is the final step in eliminating secrets from
|
||||
the repository.
|
||||
4. **Consider Sentry or equivalent error aggregation.** The structured
|
||||
logger introduced in this iteration is the prerequisite. Wiring it
|
||||
to a hosted aggregation service is a half-day task and dramatically
|
||||
improves time-to-detection for production errors.
|
||||
5. **Schedule a 30-day review of the conversation dashboard data.** The
|
||||
analytics will be most useful after a month of real traffic. At that
|
||||
point we can identify the highest-impact funnel-stage improvements
|
||||
based on actual visitor behaviour.

## Appendix B — Quick Reference for the Sales Team
|
||||
|
||||
For team members who want to use the new analytics without engineering help:
|
||||
|
||||
1. Log in to the HQ Command Center at `https://www.rf-flux.com/hq-command`.
|
||||
2. From the main dashboard, click the **FluxAI Conversations** tile (cyan
|
||||
sparkle icon, last position in the grid).
|
||||
3. The top four cards show overall numbers: total conversations,
|
||||
conversion rate, average messages, average tool calls.
|
||||
4. The two panels below show the funnel breakdown and the most common
|
||||
industries.
|
||||
5. The table lists the last fifty conversations. Click **Open** on any
|
||||
row to see the full transcript.
|
||||
6. Conversations that converted to a consultation ticket display the
|
||||
ticket ID in green at the top of the detail view.
|
||||
|
||||
The data updates in real time — no refresh needed between visits.
