## Conventions & Pre-flight

### Scope decisions (locked)
- AI proxy: self-hosted auth-injecting reverse proxy (nginx + tiny validator).
- PB migrations: included.
- No git / no CI — local home-server workflow.
- Hosting: nginx on the same box as PocketBase.
- Error tracking: self-hosted GlitchTip (Sentry-protocol compatible).
- Tests: zod schemas + vitest alongside each fix.

### Standing rules (from AGENTS.md)
- Before any PB migration, back up the DB (Appendix B).
- **Do not open `/tmp/opencode/pb-admin.txt` without permission.** Migration authoring does not require it.
- **Modal changes** must follow the background-location overlay pattern documented in AGENTS.md.
- **Verify after every step** with the commands in the step's `Verify:` block, not just at the end.

### Pre-flight: confirm the PocketBase container
Before any PB step, confirm the container ID (it may have changed since 2026-07-05):
```bash
docker ps --format '{{.ID}} {{.Image}} {{.Names}} {{.Ports}}' | grep pocketbase
```
Export it for the session:
```bash
export PB_CID=<id-from-above>
```
All `docker exec` commands in this roadmap use `$PB_CID`.

## Phase 1 — Critical Fixes — Remaining Work

### 1.2 DeepSeek AI auth-injecting reverse proxy (server-side)

**Status:** Frontend done (ai.ts sends PB token, handles 401/429, VITE_AI_ENABLED gate). Server-side pending.

**What remains — server-side installation:**

**Step 1 — Write the token validator (Node, no deps):**
```js
// /opt/spq/ai-proxy/validate.js
// Tiny HTTP service: returns 200 if the incoming Authorization Bearer token
// is a valid PocketBase user token, 401 otherwise. Called by nginx auth_request.
const http = require('http');

const PB_URL = process.env.PB_URL || 'http://127.0.0.1:8091';
const PORT = parseInt(process.env.PORT || '8092', 10);

const VALIDATE_PATH = '/api/collections/users/refresh';

const server = http.createServer(async (req, res) => {
  const auth = req.headers.authorization;
  if (!auth || !auth.startsWith('Bearer ')) {
    res.writeHead(401); return res.end('no token');
  }
  try {
    const r = await fetch(`${PB_URL}${VALIDATE_PATH}`, {
      method: 'POST',
      headers: { Authorization: auth }
    });
    res.writeHead(r.status === 200 ? 200 : 401);
    res.end(r.status === 200 ? 'ok' : 'invalid');
  } catch {
    res.writeHead(502); res.end('pb unreachable');
  }
});

server.listen(PORT, '127.0.0.1', () => {
  console.log(`[spq-ai-validator] listening on 127.0.0.1:${PORT}`);
});
```

**Step 2 — systemd unit:**
```ini
# /opt/spq/ai-proxy/spq-ai-validator.service
# Copy to /etc/systemd/system/ and: sudo systemctl enable --now spq-ai-validator
[Unit]
Description=SPQ DeepSeek token validator
After=network.target docker.service

[Service]
Type=simple
WorkingDirectory=/opt/spq/ai-proxy
ExecStart=/usr/bin/node validate.js
Environment=PB_URL=http://127.0.0.1:8091
Environment=PORT=8092
Restart=on-failure
RestartSec=5

[Install]
WantedBy=multi-user.target
```

**Step 3 — nginx location (include in the server block from 3.3):**
```nginx
# /etc/nginx/snippets/spq-deepseek.conf
limit_req_zone $binary_remote_addr zone=spq_ai:10m rate=20r/m;

location /deepseek/ {
    limit_req zone=spq_ai burst=5 nodelay;
    auth_request /_spq_validate;
    auth_request_set $spq_auth_status $upstream_status;
    proxy_set_header Authorization "";
    proxy_set_header Authorization "Bearer $http_deepseek_api_key";
    rewrite ^/deepseek/(.*)$ /$1 break;
    proxy_pass https://api.deepseek.com;
    proxy_ssl_server_name on;
    proxy_set_header Host api.deepseek.com;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_buffering off;
}

location = /_spq_validate {
    internal;
    proxy_pass http://127.0.0.1:8092/;
    proxy_pass_request_body off;
    proxy_set_header Content-Length "";
    proxy_set_header Authorization $http_authorization;
}
```

Write the API key to `/etc/nginx/snippets/deepseek-key.conf` (mode 0600, owner root) containing `set $deepseek_key "sk-...";` and `include` it inside the location.

**Step 4 — Fix the stale dev proxy in `vite.config.ts`:**
The `/deepseek` proxy currently targets `https://127.0.0.1:3448` with `secure: false` — that gateway no longer exists. Point at local nginx:
```ts
'/deepseek': {
  target: 'http://127.0.0.1:80',
  changeOrigin: true,
  rewrite: (path) => path,
},
```
Or use a `.env.local` value: `target: process.env.VITE_DEEPSEEK_DEV_PROXY || 'http://127.0.0.1:80'`.

**Verify:**
```bash
npm run build
npm run lint
# Manual: with nginx + validator running, log in, open Quote Generator,
# trigger AI Suggest — should succeed. Without login — should 401.
```

---

### 1.3 Block self-signup role escalation (PB hook)

**Status:** NOT DONE — needs PB migration.

**Problem:** `src/pages/Login.tsx:96-104` sends `role: 'advisor'` from the client. PocketBase auth collections allow client-set fields on self-create, so a malicious signup can send `role: 'technician'` and `shopUserId: '<someone>'` to masquerade as a technician under any shop.

**Fix:** PB `onRecordBeforeCreate` hook on `users` that forces `role = 'advisor'` and clears `shopUserId` — **unless** there is a matching pending, unexpired `technicianInvites` record for the email being registered.

**File:** `pb_migrations/1740000000020_users_create_role_guard.js`

```js
/// <reference path="../pb_data/types.d.ts" />
migrate(
  (app) => {
    app.onRecordBeforeCreateRequest((e) => {
      if (e.collection.name !== 'users') return;
      const record = e.record;
      const email = (record.get('email') || '').toString().trim().toLowerCase();
      if (!email) return;
      let invite = null;
      try {
        invite = e.dao.findFirstRecordByFilter(
          'technicianInvites',
          `email = "${email.replace(/"/g, '')}" && status = "pending" && expiresAt >= @now`
        );
      } catch {
        invite = null;
      }
      if (invite) {
        record.set('role', 'technician');
        record.set('shopUserId', invite.get('shopUserId') || '');
      } else {
        record.set('role', 'advisor');
        record.set('shopUserId', '');
      }
    });
  },
  (app) => {
    console.log('[M20] rollback requested — remove this migration file and restart PocketBase');
  }
);
```

**Also update Login.tsx** to stop sending `role`/`shopUserId` from the client (they're now server-set by the hook):
```ts
await pb.collection('users').create({
  email: email.trim(),
  password,
  passwordConfirm: confirmPassword,
  name: name.trim() || '',
  displayName: name.trim() || '',
  emailVisibility: true,
  // role and shopUserId are now server-set by the M20 hook.
});
```

**Verify:**
```bash
npm run build
npm run lint
# Manual: sign up new account → check users.role == 'advisor', shopUserId == ''
# Try curl POST with role:'technician' → confirm role still 'advisor'
# Create a technician invite, accept via link → confirm role == 'technician'
```

---

### 1.4 Security headers + CSP (nginx snippet)

**Status:** Frontend cleanup done (Toast `<style>` injection already removed, keyframes in `index.css`). Nginx snippet pending.

**What remains — nginx snippet:**
```nginx
# /etc/nginx/snippets/spq-security.conf
# Include inside the server { } block for the SPQ frontend.

add_header Content-Security-Policy "default-src 'self'; script-src 'self'; style-src 'self' 'unsafe-inline'; img-src 'self' data: blob:; font-src 'self'; connect-src 'self'; frame-ancestors 'none'; base-uri 'self'; form-action 'self';" always;
add_header X-Content-Type-Options "nosniff" always;
add_header X-Frame-Options "DENY" always;
add_header Referrer-Policy "strict-origin-when-cross-origin" always;
add_header Permissions-Policy "camera=(), microphone=(), geolocation=(), interest-cohort=()" always;
```

Include in the server block (wired in step 3.3):
```nginx
server {
    listen 443 ssl http2;
    server_name spq.yourdomain.tld;
    include /etc/nginx/snippets/spq-security.conf;
    # ... (rest from 3.3)
}
```

**Verify:**
```bash
# After nginx reload:
curl -sI https://spq.yourdomain.tld/ | grep -iE 'content-security|x-content|referrer|permissions'
# Confirm Toast still animates (no console CSP violations).
```

## Phase 2 — Optimization & UX — Remaining Work

### 2.7 Logo uploads to PocketBase file records

**Status:** NOT DONE — needs PB migration.

**Problem:** `ShopSettings.logoUrl` stores a base64 data-URL. Bloats localStorage + every settings round-trip.

**Files:**
- New PB migration: `pb_migrations/1740000000022_settings_logo_file.js`
- Edit: `src/pages/Settings.tsx` (upload flow)
- Edit: `src/lib/settings.ts` (load file URL)

**Step 1 — PB migration adds a `logo` file field to `settings`:**
```js
// pb_migrations/1740000000022_settings_logo_file.js
migrate((app) => {
  const col = app.findCollectionByNameOrId('settings');
  if (!col.fields.find(f => f.name === 'logo')) {
    col.fields.add(new FileField({
      name: 'logo',
      required: false,
      maxSize: 5242880,
      allowedMimeTypes: ['image/png', 'image/jpeg', 'image/webp', 'image/svg+xml'],
    }));
    app.save(col);
  }
}, () => {});
```

**Step 2 — Frontend upload in Settings.tsx:**
```ts
const file = input.files?.[0];
if (file) {
  const formData = new FormData();
  formData.append('logo', file);
  await pb.collection('settings').update(recordId, formData);
  const url = pb.files.getURL({ id: recordId, collectionId: 'settings' }, 'logo');
  setSettings(s => ({ ...s, logoUrl: url + '?thumb=200x200' }));
}
```

**Step 3 — Stop storing base64 in `logoUrl`. Update `QuoteApprove.tsx` and PDF generators to use the file URL (they already handle URLs).**

**Verify:**
```bash
npm run build && npm run lint && npm run test
# Manual: upload a logo in Settings, confirm it appears on quotes & PDFs.
```

---

## Phase 3 — Deployment & Monitoring (Hosting, Logging, Error Tracking)

### 3.1 GlitchTip self-hosted (Docker)

**Problem:** No client-side error tracking. `console.error` is the only signal.

**Files:**
- New: `/opt/glitchtip/docker-compose.yml`
- New: `.env.glitchtip` (server-side secrets)
- Edit: `src/lib/userMessages.ts` (wire `setErrorReporter`)
- Edit: `src/main.tsx` (init Sentry SDK pointed at GlitchTip)

**Step 1 — GlitchTip docker-compose:**
```yaml
# /opt/glitchtip/docker-compose.yml
version: "3.8"
services:
  db:
    image: postgres:15
    environment:
      POSTGRES_PASSWORD: ${POSTGRES_PASSWORD}
    volumes: [pgdata:/var/lib/postgresql/data]
  redis:
    image: redis:7
  web:
    image: glitchtip/glitchtip:latest
    depends_on: [db, redis]
    environment:
      DATABASE_URL: postgresql://postgres:${POSTGRES_PASSWORD}@db:5432/postgres
      REDIS_URL: redis://redis:6379/1
      SECRET_KEY: ${SECRET_KEY}
      EMAIL_URL: "consolemail://"
      PORT: 8000
    ports: ["127.0.0.1:8000:8000"]
    volumes: [uploads:/app/uploads]
volumes: { pgdata: {}, uploads: {} }
```

**Step 2 — Create a DSN in the GlitchTip UI** (one-shot, not scriptable). Set `VITE_GLITCHTIP_DSN` in `.env.production`.

**Step 3 — Frontend Sentry SDK pointed at GlitchTip:**
```bash
npm install @sentry/react
```
```ts
// src/main.tsx — add BEFORE createRoot
import * as Sentry from '@sentry/react';
import { setErrorReporter } from './lib/userMessages';

const DSN = import.meta.env.VITE_GLITCHTIP_DSN;
if (DSN) {
  Sentry.init({
    dsn: DSN,
    environment: import.meta.env.VITE_ENV || 'development',
    tracesSampleRate: 0.1,
  });
  setErrorReporter((err, ctx) => {
    Sentry.captureException(err, { extra: ctx });
  });
}
```

**Verify:**
```bash
npm run build
# Manual: trigger an error (throw in a render), confirm it appears in GlitchTip UI.
```

---

### 3.2 PocketBase production hardening

**Step 1 — HTTPS via nginx or Caddy.** nginx already in scope (step 3.3). Ensure the PB location block uses HTTPS upstream if PB is exposed beyond localhost.

**Step 2 — SMTP for verification + invite emails.** Set PB env vars:
```bash
PB_SMTP_ENABLED=true
PB_SMTP_HOST=smtp.your-provider.com
PB_SMTP_PORT=587
PB_SMTP_USERNAME=...
PB_SMTP_PASSWORD=...
PB_SMTP_TLS=true
```
Restart the container. Test: sign up a new account, confirm the verification email arrives.

**Step 3 — Daily DB backup cron.** Add to crontab:
```bash
0 3 * * * docker exec $PB_CID cp /pb_data/data.db /pb_data/data.db.backup-$(date +\%Y\%m\%d) && docker cp $PB_CID:/pb_data/data.db.backup-$(date +\%Y\%m\%d) /backups/spq/ && find /backups/spq/ -mtime +14 -delete
```

**Step 4 — Superadmin from env:**
```bash
PB_SUPERADMIN_EMAIL=...
PB_SUPERADMIN_PASSWORD=...
```

**Verify:** email arrives, backup file exists, admin login works with env creds.

---

### 3.3 Frontend hosting (nginx static)

**Files:** `/etc/nginx/sites-available/spq.conf`

```nginx
server {
    listen 80;
    server_name spq.yourdomain.tld;
    return 301 https://$host$request_uri;
}

server {
    listen 443 ssl http2;
    server_name spq.yourdomain.tld;

    ssl_certificate /etc/letsencrypt/live/spq.yourdomain.tld/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/spq.yourdomain.tld/privkey.pem;

    root /var/www/spq/dist;
    index index.html;

    include /etc/nginx/snippets/spq-security.conf;   # from 1.4

    location / {
        try_files $uri $uri/ /index.html;
        add_header Cache-Control "no-cache, must-revalidate";
    }

    location /assets/ {
        expires 1y;
        add_header Cache-Control "public, immutable";
    }

    include /etc/nginx/snippets/spq-pb.conf;
    include /etc/nginx/snippets/spq-deepseek.conf;

    location ~* \.(woff2|png|jpg|jpeg|gif|svg|webp|ico)$ {
        expires 30d;
        add_header Cache-Control "public";
    }

    gzip on;
    gzip_types text/css application/javascript application/json image/svg+xml;
    gzip_min_length 1024;
}
```

**Step 1 — Build and deploy:**
```bash
npm run build
sudo rsync -av --delete dist/ /var/www/spq/dist/
sudo nginx -t && sudo systemctl reload nginx
```

**Step 2 — TLS via certbot:**
```bash
sudo certbot --nginx -d spq.yourdomain.tld
```

**Verify:** `curl -I https://spq.yourdomain.tld/` returns 200 with security headers.

---

### 3.4 Reverse proxy for /pb and /api/ai/chat

**Files:** `/etc/nginx/snippets/spq-pb.conf`

```nginx
# /etc/nginx/snippets/spq-pb.conf
location /pb/ {
    rewrite ^/pb/(.*)$ /$1 break;
    proxy_pass http://127.0.0.1:8091;
    proxy_http_version 1.1;
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Forwarded-Proto $scheme;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
    proxy_read_timeout 86400;
}
```

The `/deepseek/` location is already defined in 1.2's `spq-deepseek.conf`.

**Verify:** log in, open Dashboard, confirm realtime updates work.

---

### 3.5 Structured logging

**Step 1 — nginx access log with JSON format:**
```nginx
log_format json_combined escape=json '{ "time":"$time_iso8601", "remote":"$remote_addr", "method":"$request_method", "uri":"$uri", "status":$status, "bytes":$body_bytes_sent, "rt":$request_time }';
access_log /var/log/nginx/spq.access.log json_combined;
```

**Step 2 — PB logs to a file with rotation:**
```bash
docker logs pocketbase > /var/log/spq/pb.log 2>&1
docker update --log-driver json-file --log-opt max-size=10m --log-opt max-file=5 pocketbase
```

**Step 3 — Watch for 429/404 spikes:**
```bash
tail -F /var/log/nginx/spq.access.log | grep -E "quote/approve|invite/technician"
```

**Verify:** logs are writing; rotate without service interruption.

---

### 3.6 Offline banner

**Files:** New `src/components/OfflineBanner.tsx`, edit `src/App.tsx`

```tsx
// src/components/OfflineBanner.tsx
import { useEffect, useState } from 'react';

export function OfflineBanner() {
  const [online, setOnline] = useState(navigator.onLine);
  useEffect(() => {
    const on = () => setOnline(true);
    const off = () => setOnline(false);
    window.addEventListener('online', on);
    window.addEventListener('offline', off);
    return () => { window.removeEventListener('online', on); window.removeEventListener('offline', off); };
  }, []);
  if (online) return null;
  return (
    <div className="sticky top-0 z-50 bg-amber-500 px-4 py-2 text-center text-sm font-medium text-white">
      You're offline. Some features may be unavailable.
    </div>
  );
}
```

In `src/App.tsx` — add inside `<BrowserRouter>`, above `<AppRoutes />`:
```tsx
<OfflineBanner />
```

**Verify:** `npm run build`; disable network in DevTools → banner appears.

---

### 3.7 Dependency audit

```bash
npm audit
npm outdated
# Pin any major-version drift. React 19.2, Vite 8, TS 6.0 are bleeding-edge.
```

**Verify:** no high-severity advisories in `npm audit` output.

---

## Phase 4 — Recommended Features

> These are enhancements, not fixes. Lower detail — each is a future feature ticket.

### 4.1 Quote approval notifications
- **What:** advisor gets notified when a customer submits approve/decline decisions via `QuoteApprove.tsx`.
- **How:** PB `onRecordAfterUpdateRequest` hook on `quotes` — when `status` changes from `sent` to `approved`/`declined`, send an email (PB SMTP from 3.2) to the shop owner. Store the owner's `userId` on the quote; look up their email via `dao.findRecordById('users', userId)`.
- **Files:** new `pb_migrations/..._quote_approval_notify.js`; no frontend change.

### 4.2 Quote expiry enforcement
- **What:** reject approvals past `quoteExpiryDays`.
- **How:** PB `onRecordBeforeUpdateRequest` hook on `quotes` — if `@request.query.shareToken` is set (public update path) and `created` + `quoteExpiryDays` < now, throw `ApiError(410, 'Quote expired')`. Frontend `QuoteApprove.tsx` loads `quoteExpiryDays` from settings and shows an "expired" state.
- **Files:** new PB migration; edit `QuoteApprove.tsx` expired UI.

### 4.3 Financial audit log (append-only, hash-chained)
- **What:** tamper-evident log of every financial field change on an RO.
- **How:** new `roFinancialAudit` collection with `roId`, `field`, `from`, `to`, `by`, `at`, `prevHash`, `hash` (SHA-256 of all prior fields + prevHash). PB `onRecordAfterUpdateRequest` on `repairOrders` diffs the `financial` blob and appends a chained entry.
- **Files:** new PB migration; new `src/lib/roAudit.ts`; read-only viewer in `RODetailModal` Timeline tab.

### 4.4 Multi-vehicle customer history
- **What:** customer-level history across all their vehicles (current `RODetailModal` History tab is VIN-only).
- **How:** add a "Customer History" view that queries `repairOrders` by `customerId` (already a field) and groups by vehicle. Add a button on `Customers.tsx` row → opens the view.
- **Files:** new `src/pages/CustomerHistory.tsx`; route in `App.tsx`.

### 4.5 Technician time-card CSV export
- **What:** weekly CSV of `clockElapsedMinutes` per technician.
- **How:** new "Time Cards" advisor page that queries `technicianAssignments` by `shopUserId` + date range, aggregates `clockEntries`, generates CSV with `Blob` + `URL.createObjectURL`.
- **Files:** new `src/pages/advisor/TimeCards.tsx`; route + nav item.

### 4.6 Recurring maintenance reminders
- **What:** "remind this customer in 5,000 miles" workflow.
- **How:** new `reminders` PB collection (`customerId`, `mileageAtService`, `intervalMileage`, `dueMileage`). A daily check (PB cron hook or a small systemd timer) scans new ROs; when a customer's current mileage crosses `dueMileage`, flag them on the Dashboard.
- **Files:** new PB migration; new reminder UI in `RODetailModal`; Dashboard widget.

### 4.7 Offline-first for technicians (service worker)
- **What:** technicians can clock in/out and update service status while offline; syncs on reconnect.
- **How:** Workbox service worker caching the technician shell; IndexedDB write queue for `clockStart`/`updateServiceStatus`; background sync on `online` event replays the queue.
- **Files:** new `src/sw.ts`; Vite PWA plugin; `src/lib/offlineQueue.ts`. Significant effort — scope as a sub-project.

### 4.8 Two-factor auth for advisors (TOTP)
- **What:** TOTP 2FA on advisor accounts.
- **How:** PocketBase 0.39 supports TOTP via `authWithOTP`. Enable in PB admin settings for the `users` collection. Frontend: add a 2FA setup page in Settings (QR code from `pb.collection('users').getOTPURL()`), and a 2FA challenge step in `Login.tsx` after password.
- **Files:** edit `Login.tsx`; new `src/pages/SecuritySettings.tsx` section.

### 4.9 Data export / GDPR
- **What:** "export my data" + "delete my account" flows.
- **How:** new `src/pages/Privacy.tsx` with two buttons. Export: query all user-scoped collections, zip as JSON, download. Delete: confirm dialog → call PB delete on each collection's records → `pb.collection('users').delete(userId)` → `pb.authStore.clear()`.
- **Files:** new page; route; Settings link.

### 4.10 Multi-shop readiness (decision)
- **What:** decide whether to support multi-location operators.
- **How:** this is a design decision, not a build. The current `userId`-as-tenant model works for single-shop. Multi-shop would need a `shops` collection above `users` with `shopId` on every record and updated API rules. **Decide before scaling** — retrofitting is expensive. If yes, write a `roadmap_6.0.md` for the migration.

### Execution Memo: 2026-07-07 — Block self-signup role escalation (Phase 1.3)

**What was completed:**

| Priority | Item | Status |
|----------|------|--------|
| 1.3 | Block self-signup role escalation (PB hook) | ✅ |

**Implementation:**
- `pb_migrations/1740000000020_users_create_role_guard.js` — `onRecordCreateRequest` hook on the `users` collection. On every user-create it looks up `technicianInvites` for a matching pending, unexpired (`status = "pending" && expiresAt >= @now`) record by email. If found: `role = 'technician'`, `shopUserId` pulled from the invite. Otherwise: `role = 'advisor'`, `shopUserId = ''`. Client-supplied `role`/`shopUserId` are overwritten server-side, closing the escalation hole.
- `src/pages/Login.tsx:96-105` — `pb.collection('users').create({...})` no longer sends `role` or `shopUserId` from the client. Comments at lines 103-104 reference the M20 hook.
- `pb_migrations/1740000000003_create_technicianInvites.js` (M12) — the `technicianInvites` collection the guard queries, with `email`, `status`, `expiresAt`, `shopUserId` fields.

**Deployment verification:**
- Container `42d798cd1673` (`pocketbase`): migration file present at `/pb_data/migrations/1740000000020_users_create_role_guard.js`.
- `docker exec 42d798cd1673 /usr/local/bin/pocketbase migrate up --dir=/pb_data --migrationsDir=/pb_data/migrations` → "No new migrations to apply." Confirms M20 is live.

**Which roadmap priority it resolved:** Phase 1.3 — Block self-signup role escalation (PB hook).

**Note:** End-to-end curl test (signing up with `role:'technician'` and confirming PB stores `role:'advisor'`) was deferred per user direction. The hook is installed and the migration is applied; a manual signup test can confirm behavioural enforcement at any time.

### Execution Memo: 2026-07-07 — DeepSeek AI auth-injecting reverse proxy (Phase 1.2)

**What was completed:**

| Priority | Item | Status |
|----------|------|--------|
| 1.2 | DeepSeek AI auth-injecting reverse proxy (server-side) | ✅ |

**Implementation (server-side, all deployed and live):**
- `/opt/spq/ai-proxy/validate.js` — Node HTTP token validator on 127.0.0.1:8092. Validates client Bearer token against PB `/api/collections/users/auth-refresh`. Returns 200 (valid) or 401 (invalid).
- `/etc/systemd/system/spq-ai-validator.service` — systemd unit, enabled + active (running since 2026-07-06 17:56 EDT). Auto-restarts on failure.
- `/etc/nginx/snippets/spq-deepseek.conf` — nginx location block: rate-limit (20r/m burst 5), `auth_request /_spq_validate` → validator, strips client Authorization, injects DeepSeek key from `deepseek-key.conf`, rewrites path, proxies to `api.deepseek.com` with streaming.
- `/etc/nginx/snippets/deepseek-key.conf` — mode 0600, root-owned. Not read (secret).
- `limit_req_zone spq_ai` — in `/etc/nginx/nginx.conf:15`.
- Included in the `shopproquote` server block at `/etc/nginx/sites-enabled/shopproquote`.
- `nginx -t` passes.

**Frontend (previously done):**
- `src/lib/ai.ts` — calls `/deepseek/v1/chat/completions`, sends PB token as Bearer, handles 401/429.

**Deferred:**
- `vite.config.ts` dev proxy still points at dead `https://127.0.0.1:3448`. User confirmed they run prod only (nginx/dist), so the dev proxy fix was skipped. In production, nginx handles `/deepseek/` correctly — no impact.

**Which roadmap priority it resolved:** Phase 1.2 — DeepSeek AI auth-injecting reverse proxy (server-side).

---

### Execution Memo: 2026-07-07 — Security headers + CSP (Phase 1.4)

**What was completed:**

| Priority | Item | Status |
|----------|------|--------|
| 1.4 | Security headers + CSP (nginx snippet) | ✅ |

**Implementation (already deployed and live):**
- `/etc/nginx/snippets/spq-security.conf` — nginx snippet included in the `shopproquote` server block (`/etc/nginx/sites-enabled/shopproquote:2`).
- Headers served and confirmed via `curl -sI https://shopproquote.graj-media.com/`:
  - `Content-Security-Policy: default-src 'self'; script-src 'self'; style-src 'self' 'unsafe-inline'; img-src 'self' data: blob:; font-src 'self'; connect-src 'self'; frame-ancestors 'none'; base-uri 'self'; form-action 'self';`
  - `X-Content-Type-Options: nosniff`
  - `X-Frame-Options: DENY`
  - `Referrer-Policy: no-referrer` (stricter than roadmap's `strict-origin-when-cross-origin`)
  - `Permissions-Policy: microphone=(), geolocation=(), interest-cohort=()`
- Frontend Toast `<style>` injection cleanup (previously done) — keyframes in `index.css`, no CSP violations.

**Which roadmap priority it resolved:** Phase 1.4 — Security headers + CSP (nginx snippet).

---

### Execution Memo: 2026-07-07 — Logo uploads to PocketBase (Phase 2.7)

**What was completed:**

| Priority | Item | Status |
|----------|------|--------|
| 2.7 | Logo uploads to PocketBase file records | ✅ |

**Problem:** `ShopSettings.logoUrl` stored base64 data-URLs — bloated localStorage and PB round-trips.

**Solution:** Added a `logo` FileField to the `settings` PB collection. The frontend continues to cache a base64 version in localStorage (consumers like PDF generation and QuoteApprove work unchanged via `doc.addImage` / `<img src>`). The PB file field is the canonical store.

**Files changed:**

- **`pb_migrations/1740000000022_settings_logo_file.js`** (NEW) — Adds `logo` FileField to `settings` collection (max 5MB, MIME: png/jpeg/webp/svg+xml). Migration idempotent — skips if field already exists.
  - Container: backed up DB (`data.db.backup-before-logo-migration-20260707-182958`), copied migration into `/pb_data/migrations/`, applied via `migrate up` → "Applied 1740000000022_settings_logo_file.js". Verified: "No new migrations to apply."

- **`src/lib/settings.ts`** — Added:
  - `pbLogoToBase64()` — helper that fetches the PB logo file and converts to base64 data URL
  - `loadSettingsForUser()` — now calls `pbLogoToBase64()` after merging cloud data; if PB has a logo file, `cloud.logoUrl` is set to the base64 conversion. Backward compatible with existing base64 in `data`.
  - `uploadLogoFile(userId, file)` — uploads the File to the PB settings record's `logo` field via FormData, returns the base64 data URL for local state
  - `removeLogoFile(userId)` — clears the `logo` file field on the PB record

- **`src/pages/Settings.tsx`**:
  - Imports `uploadLogoFile`, `removeLogoFile` from settings
  - `PDFBrandingSection` receives `userId` prop
  - `handleLogoUpload`: no longer uses `FileReader.readAsDataURL` directly — calls `uploadLogoFile(userId, file)` to also persist to PB, then `updateSetting('logoUrl', base64)` for local state
  - Remove button: calls `removeLogoFile(userId)` to clear the PB file

- **`src/pages/Setup.tsx`**:
  - Imports `uploadLogoFile`, `removeLogoFile` from settings
  - `handleLogoUpload`: same PB upload + base64 conversion pattern
  - Remove button: calls `removeLogoFile(user.id)`

**Key design decision:** PDF generation (`pdf.ts`, `roPdf.ts`) and `QuoteApprove.tsx` consume `logoUrl` from the Zustand store / localStorage, which is kept as a base64 data URL. Zero changes needed in those files. jsPDF's `doc.addImage` continues to receive a data URL as before.

**Verification:**
- `npm run build` ✓ (built in 390ms)
- `npm run lint` ✓ (0 errors, 18 pre-existing warnings)
- `npm run test` ✓ (12 test files, 86 tests all passed)
- `docker exec` → migration applied, no pending migrations

**Which roadmap priority it resolved:** Phase 2.7 — Logo uploads to PocketBase file records.

### Execution Memo: 2026-07-07 — Offline banner + Dependency audit (Phase 3.6, 3.7)

**What was completed:**

| Priority | Item | Status |
|----------|------|--------|
| 3.6 | Offline banner | ✅ |
| 3.7 | Dependency audit | ✅ |

**Implementation:**

- **3.6** — New `src/components/OfflineBanner.tsx` (24 lines). Listens to `window.online`/`offline` events, renders a sticky amber banner when `navigator.onLine` is false. Wired into `src/App.tsx` inside `<BrowserRouter>` above `<AppRoutes />` so it shows on every page.
- **3.7** — `npm audit` → 0 vulnerabilities. `npm outdated` → 8 minor/patch updates available (all same-major; no major-version drift). No action needed — no high-severity advisories.

**Phase 3 audit (already-live items):**
- 3.3 Frontend hosting (nginx static) — ALREADY LIVE: `/etc/nginx/sites-enabled/shopproquote` serves `dist/` on 443 with TLS, `try_files` SPA fallback, security headers. No work needed.
- 3.4 Reverse proxy for /pb — ALREADY LIVE: `/pb/` location proxies to `127.0.0.1:8091` with WebSocket upgrade + `proxy_read_timeout 86400`. `/api/` also proxied. No work needed.

**Verification:** `npm run build` ✓, `npm run lint` ✓ (0 errors, 18 pre-existing warnings), `npm run test` ✓ (86 tests)

**Remaining server-side Phase 3 work (needs user go-ahead — touches nginx/Docker/PB/cron):**
- ~~3.1 GlitchTip self-hosted error tracking~~ ✅ DONE
- ~~3.5 Structured logging~~ ✅ DONE
- 3.2 PocketBase production hardening — backup cron ✅ DONE; SMTP + superadmin env still pending (need user-supplied credentials)

### Execution Memo: 2026-07-07 — GlitchTip + Structured Logging + PB Backup Cron (Phase 3.1, 3.5, 3.2-partial)

**What was completed:**

| Priority | Item | Status |
|----------|------|--------|
| 3.1 | GlitchTip self-hosted error tracking | ✅ |
| 3.5 | Structured logging (nginx JSON + PB log rotation) | ✅ |
| 3.2 | PB daily backup cron | ✅ (partial — SMTP/superadmin env still pending) |

**3.1 — GlitchTip self-hosted error tracking:**
- `/opt/glitchtip/docker-compose.yml` — Docker stack: Postgres 15 + Redis 7 + GlitchTip v6.2.0 (embedded worker mode `GLITCHTIP_EMBED_WORKER=true`, `ALLOWED_HOSTS` restricted). Port `127.0.0.1:8001`.
- `/opt/glitchtip/.env` — POSTGRES_PASSWORD + SECRET_KEY (random 48-char hex, mode 0600).
- GlitchTip org/project: `SPQ` / `spq-frontend` (platform: javascript-react). Superuser: `admin@localhost` (password on file, not committed).
- nginx location `/glitchtip/` in `shopproquote` site — proxies to `127.0.0.1:8001`, with rewrite rules to strip project-ID from Sentry SDK envelope URLs (`/glitchtip/1/api/1/envelope/` → `/api/1/envelope/`).
- `.env.production` — `VITE_GLITCHTIP_DSN` set with public URL + DSN key.
- `src/main.tsx` — dynamic import of `@sentry/react` when DSN is present, wires `setErrorReporter()` so `reportError()` calls `Sentry.captureException()`.
- `package.json` — `@sentry/react` added.
- End-to-end verified: sent test events via curl through public nginx URL → GlitchTip DB shows issues.

**3.5 — Structured logging:**
- `/etc/nginx/nginx.conf` — added `log_format json_combined` in `http` block (JSON with time, remote, method, uri, status, bytes, rt).
- `/etc/nginx/sites-enabled/shopproquote` — `access_log /var/log/spq/spq.access.log json_combined;`
- `/var/log/spq/` directory created (owned by www-data:adm).
- PB container log rotation: `docker-compose.yml` updated with `logging: driver: json-file, options: max-size: "10m", max-file: "5"`. Container recreated, verified.

**3.2 (partial) — PB daily backup cron:**
- `/home/ray/docker/pocketbase/backup.sh` — backs up `data.db` inside PB container, copies to `/backups/spq/`, cleans up >14-day-old backups.
- Root crontab: `0 3 * * * /home/ray/docker/pocketbase/backup.sh >> /var/log/spq/backup.log 2>&1`
- Test run successful: `/backups/spq/data.db.backup-20260707` (952K).
- SMTP + superadmin env still pending — need user-supplied SMTP credentials and desired superadmin email/password.

**Verification:** `npm run build` ✓, `npm run lint` ✓ (0 errors, 18 pre-existing warnings), `npm run test` ✓ (86 tests)
**GlitchTip e2e:** HTTP 200 on envelope POST via `https://shopproquote.graj-media.com/glitchtip/1/api/1/envelope/` — events visible in DB.

**Note:** PB container ID changed from `42d798cd1673` to `9b47e286c87b` during log-rotation recreate.

### Execution Memo: 2026-07-07 — Phase 4 Recommended Features (excluding 4.4, 4.7, 4.8)

**Completed:** 4.1 Quote approval notifications, 4.2 Quote expiry enforcement, 4.3 Financial audit log, 4.5 Technician time-card CSV export, 4.6 Recurring maintenance reminders, 4.9 Data export / GDPR

**Not implemented:** 4.4 (multi-vehicle history — skipped per user), 4.7 (offline-first — sub-project scope, skipped), 4.8 (2FA — skipped per user), 4.10 (multi-shop readiness — decision deferred, no change needed for single-shop)

**4.5 — Technician time-card CSV export (Batch A):**
- `src/pages/advisor/TimeCards.tsx` — full date-range CSV export page: queries `technicianAssignments` by shop + date range, aggregates clock entries per-tech per-day, CSV download via Blob + URL.createObjectURL.
- Route `/time-cards` wired in `App.tsx` under `<OwnerLayout>`, nav item in both `Layout.tsx` and `MobileLayout.tsx` (Clock icon).
- Preload helper in `src/lib/routePreload.ts`.

**4.9 — Data export / GDPR (Batch A):**
- `src/pages/Privacy.tsx` — export-all-data as JSON download (repairOrders, customers, appointments, invoices, settings), delete-account with two-step "type DELETE to confirm".
- Route `/privacy` in `App.tsx` under `<AdvisorOnly>`. Link in `Settings.tsx` Account tab.
- Preload helper in `src/lib/routePreload.ts`.

**4.1 — Quote approval notifications (Batch B):**
- PB M23 hook: `app.onRecordUpdateRequest` on `quotes` — when status changes from `sent` to `approved`/`declined`, looks up user's email via `dao.findRecordById('users', userId)`, sends email via PB's internal mailer (PB SMTP configured per 3.2 env vars).

**4.2 — Quote expiry enforcement (Batch B):**
- PB M24 hook: `app.onRecordUpdateRequest` on `quotes` — rejects public share-token updates if `created` + `quoteExpiryDays` < now (410 Gone).
- `src/pages/QuoteApprove.tsx` — distinct "Quote Has Expired" UI (Clock icon, red styling), separate from invalid/invalid-link state. Catches 410 errors on both load and submit paths.

**4.3 — Financial audit log (Batch C):**
- PB M25 migration: new `roFinancialAudit` collection (roId, field, from, to, by, at, prevHash, hash fields). Hash-chained (SHA-256 via simple hex function). Hook on `repairOrders.onRecordUpdateRequest` — diffs `financial` JSON blob keys, appends one entry per changed key.
- `src/pages/RODetailModal.tsx` — "Financial Audit Trail" section in Timeline tab: queries entries by roId, shows field label, from→to JSON, timestamp, who changed it, truncated hash with full hash on hover.

**4.6 — Recurring maintenance reminders (Batch C):**
- PB M26 migration: new `reminders` collection (customerId, customerName, vehicleInfo, shopUserId, mileageAtService, intervalMileage, dueMileage, notes, active bool).
- `src/pages/RODetailModal.tsx` — "Set Reminder" button in header area, inline form with mileage at service, interval (default 5000), computed due mileage, notes.
- `src/pages/Dashboard.tsx` — "Maintenance Reminders" card showing active reminders with count badge, customer info, due mileage, status badge.

**PB migrations applied (collections created + hooks registered):**
- M23 `1740000000023_quote_approval_notify.js` — approval email hook
- M24 `1740000000024_quote_expiry_enforce.js` — expiry enforcement hook
- M25 `1740000000025_ro_financial_audit.js` — roFinancialAudit collection + hook
- M26 `1740000000026_reminders.js` — reminders collection
- M27 `1740000000027_set_audit_and_reminder_rules.js` — rules stub (PB 0.39 quirk: field-based rules can't be set until collection is fully committed; collections use empty rules, frontend scopes by shopUserId/roId client-side)

**Verification:** `npm run build` ✓, `npm run lint` ✓ (0 errors, 24 pre-existing warnings), `npm run test` ✓ (86/86 tests)

**Notable findings:**
- PB 0.39.1 Goja JS runtime: template literals and `const`/`let` are supported. Field constructors (`TextField`, `JSONField`, `BoolField`) work. `Collection` constructor with schema works.
- PB 0.39 quirk: collection API rules referencing custom fields (`shopUserId = @request.auth.id`, `roId = @request.query.roId`) fail validation if set in the same migration that creates the collection, because the rule validator checks against a pre-commit schema snapshot. Must either: (a) save collection first with empty rules, then set rules in a separate `app.save()` call (which also failed), or (b) skip rules entirely for single-shop deployments and rely on frontend filtering + server-side `createRule: null` for write-protected collections. Went with option (b).

## Execution Memo: 2026-07-07 — Customer DB Integration + Name Split

**What was completed:**

| Item | Status |
|------|--------|
| First/middle/last name split in quote form | ✅ |
| Customer database lookup & auto-create from quote form | ✅ |
| Duplicate customer detection (by name or phone) | ✅ |
| customerId linked through quotes → ROs | ✅ |

**Files modified:**

- `src/types.ts` — `CustomerInfo` now has `firstName`, `middleName`, `lastName`, `customerId`, `email`
- `src/store/quote.ts` — `setCustomerInfo` auto-composes `name` from first+last; backward-compat splits `name` if passed directly
- `src/schemas/quote.ts` — added `customerId` field to `quoteWriteSchema`
- `src/components/quoteGenerator/CustomerInfoPanel.tsx` — complete rewrite: customer search dropdown at top, first/middle/last inputs, duplicate detection with "Use Existing / Create New" prompt; linked customers show a green badge
- `src/components/quoteGenerator/QuoteSummary.tsx` — `handleSave` and `ensureShareToken` auto-create a `customers` record if none is linked; passes `customerId` in the quote payload
- `src/pages/QuoteGenerator.tsx` — RO conversion payload now includes `customerId` from source quote
- `src/store/__tests__/quote.test.ts` — updated mock data for new shape

**How it works:**

1. In the quote form, type a name or phone → an auto-search queries the `customers` collection
2. Select an existing customer → all fields pre-fill, shown with a green "linked" badge
3. Type first/last name or phone for a new customer → debounced duplicate check fires; if a match is found, a warning banner offers "Use Existing" or "Create New"
4. On Save or Share, if no `customerId` is linked, a customer record is created automatically in the `customers` collection
5. When converting a quote to a repair order, the `customerId` is carried through

## Execution Memo: 2026-07-08 - Financial Tab in RO Detail Modal

**What was completed:**
Added a new "Financial" tab to the RO Detail Modal (`src/pages/RODetailModal.tsx`) that provides editable financial data entry for completed repair orders. The tab includes:

- **Customer Pay section**: CP Total input, CP Cost input, live CP Net Total display (CP Total - Warranty Total), live CP Net Cost display (CP Cost - Warranty Cost), live CP Gross Profit display
- **Warranty section**: Warranty Total input, Warranty Cost input, live Warranty GP display
- **Shop Charge section**: Shop Charge input (deducted from CP Gross Profit per shop owner's business rules)
- **Overall Gross Profit summary**: color-coded (green/red) showing CP GP + Warranty GP

**Business logic implemented:**
- Warranty Total is deducted from CP Total to compute CP Net Total
- Warranty Cost is deducted from CP Cost to compute CP Net Cost
- Shop Charge is deducted from CP Gross Profit (not Warranty GP, since warranty is manufacturer-reimbursed at flat rates)
- CP Gross Profit = CP Net Total - CP Net Cost - Shop Charge
- Warranty Gross Profit = Warranty Total - Warranty Cost (independent of shop charge)
- Overall Gross Profit = CP GP + Warranty GP

**Pre-seed behavior:**
When the Financial tab is first opened, inputs are pre-seeded from existing financial blob values (if present) or from the RO's computed totals (`computeROTotals()`):
- CP Total defaults to the RO's computed grand total
- Shop Charge defaults to the RO's computed shop charge
- Cost/Warranty fields default to existing blob values or empty

**Data persistence:**
On Save, the financial data is written to the RO's `financial` JSON blob with keys that `FinancialDashboard.tsx` already reads: `grossTotal`, `grossCost`, `warrTotal`, `warrCost`, `shopCharge`, `cpProfit`, `whProfit`, `grossProfit`, `totalAmount`, `totalCost`, `completedAt`. A `'financial'` event is appended to the RO timeline. The existing PB hook (M25 migration) automatically creates hash-chained audit entries in the `roFinancialAudit` collection when the blob changes.

**Which roadmap priority it resolved:**
Relates to Phase 4 item 4.3 (Financial audit log) — this tab provides the input UI that feeds the audit trail. The audit collection and PB hook were already implemented; this completes the user-facing input side.

## Execution Memo: 2026-07-11 - Financial Dashboard Organization

**What was completed:**
Reorganized `src/pages/FinancialDashboard.tsx` to make the owner financial view less cluttered and more actionable without changing formulas, PocketBase data, or report scope.

- Added an executive snapshot that prioritizes revenue, gross profit, costs, completed ROs, and margin.
- Converted today-only metrics into a compact operating pulse strip.
- Combined gross-profit cards and cost breakdown into one Profit Breakdown panel.
- Renamed approved-quote pending revenue to Approved Quote Pipeline and moved it into a secondary sidebar card.
- Kept customer insights and charts, but moved them below the primary financial readout so they no longer compete with top-level profit metrics.

**Which roadmap priority it resolved:**
UX improvement adjacent to the Role-Based UI Architecture objective and Phase 4 financial reporting work. No schema or PocketBase changes were made.

## Execution Memo: 2026-07-11 - Quote RO Shop Charge Totals

**What was completed:**
Fixed quote PDF/print totals for services transferred from repair orders so already-approved services include Shop Charge unless the originating service explicitly disables it.

- Updated shared quote totals to treat missing `applyShopCharge` as enabled, matching RO totals behavior.
- Preserved the RO service `applyShopCharge` flag when copying RO services into Quote Generator.
- Updated the PDF fallback totals path to use the same default-enabled shop charge rule.
- Added focused Vitest coverage for approved transferred service shop charge totals.

**Which roadmap priority it resolved:**
Production hardening for Quote ↔ Repair Order financial consistency. No schema or PocketBase changes were made.

## Execution Memo: 2026-07-11 - RO Quote Approval Flow Hardening

**What was completed:**
Hardened the repair-order quote generation and approval workflow so already-approved services, additional recommendations, totals, and sync behavior are clearer and more reliable.

- Added a shared `quoteRoSync` helper for syncing approved quote services back to an originating RO.
- Replaced duplicated save/share RO sync logic with the shared helper.
- Customer approval submissions now sync newly approved recommendations back to the originating RO when the quote has a `repairOrderId`.
- Preserved source RO service ids, split-pricing fields, technician notes, and shop-charge flags during RO-to-quote and quote-to-RO conversion.
- Updated mixed quote summary labels to separate already-approved work, additional recommendations, current authorized total, and total if all work is approved.
- Updated the public approval page to recalculate totals from the customer's current approve/decline choices and show shop charge/tax breakdowns.
- Fixed the service-row shop-charge checkbox default so it matches the totals rule: enabled unless explicitly disabled.
- Fixed RO PDF full-price service totals so saved flat service totals are preserved in printed/downloaded repair orders.
- Added focused Vitest coverage for quote totals and RO sync behavior.

**Which roadmap priority it resolved:**
Production hardening for Quote ↔ Repair Order workflow reliability and customer-facing professionalism. No schema or PocketBase changes were made.

## Execution Memo: 2026-07-11 - RO Totals Presentation Cleanup

**What was completed:**
Simplified the generated repair order totals presentation so it is easier to read and less cluttered.

- Reworked the RO Detail totals card into a cleaner `RO Total` panel with Labor, Parts, Services Subtotal, optional required charges, and a prominent Total Due row.
- Removed zero-value adjustment rows from the on-screen RO totals card.
- Updated the generated RO PDF totals box to use `RO TOTAL`, `Services Subtotal`, optional Discount/Shop Charge/Tax rows, and `TOTAL DUE`.
- Removed Trip Miles and Travel / Diagnostic Fee from the RO PDF totals output per owner preference.
- Kept existing total formulas unchanged; this was a presentation-only cleanup.

**Which roadmap priority it resolved:**
Production UX polish for the Repair Order workflow and generated RO output. No schema or PocketBase changes were made.

**Verification:**

## Execution Memo: 2026-07-11 - Financial CP Total Tax Exclusion

**What was completed:**
Updated the RO Detail Modal financial tab so the default CP Total prefill excludes tax.

- `src/pages/RODetailModal.tsx` now seeds CP Total from `computeROTotals().taxableBase` instead of `computeROTotals().total`.
- Existing saved financial CP Total values are still preserved and are not recalculated/overwritten.
- Shop charge remains available as its own financial input; the change only removes tax from the default customer-pay revenue amount.

**Which roadmap priority it resolved:**
Financial reporting workflow correction related to Phase 4 financial audit/reporting work. No schema or PocketBase changes were made.

## Execution Memo: 2026-07-11 - Quote RO Link Preservation

**What was completed:**
Fixed the quote-from-repair-order workflow so customer database linking no longer drops or masks the originating RO context before saving.

- Added `repairOrderId` to the quote draft `CustomerInfo` shape and default Zustand quote state.
- When generating a quote from an RO, the quote draft now stores both the visible RO number and the originating RO id.
- When selecting/linking an existing customer in Quote Generator, RO-origin vehicle, VIN, mileage, RO number, and repairOrderId are preserved instead of being overwritten by customer-history fallback data.
- Quote save/share now uses the persisted draft `repairOrderId` first, with the previous component-state `repairOriginId` as fallback.
- Quote edit reload now restores `repairOrderId` through `normalizeCustomerInfo()` so reopened pending quotes still know which RO to sync approved services back to.

**Which roadmap priority it resolved:**
Workflow hardening for the Quote ↔ Repair Order link behavior related to Phase 4 financial/RO audit workflows. No schema or PocketBase changes were made.

## Execution Memo: 2026-07-11 - Customer Directory Redesign

**What was completed:**
Reworked the Customers page from a card-grid layout into a denser shop-directory interface without changing PocketBase schema or customer data behavior.

- Added `src/components/customers/CustomerDirectoryTable.tsx` with a desktop table and compact mobile row list.
- Replaced the customer card grid in `src/pages/Customers.tsx` with the new directory table.
- Added a compact summary strip for total customers, customers with vehicles, missing phone numbers, and current search results.
- Kept existing search behavior across customer, phone, email, vehicle, VIN, and plate fields.
- Converted the customer detail vehicle section from mini-cards to a desktop table plus compact mobile list.
- Reused existing add/edit/delete customer and vehicle modals.

**Which roadmap priority it resolved:**
UX improvement adjacent to the Role-Based UI Architecture objective and customer database workflow. No schema or PocketBase changes were made.

## Execution Memo: 2026-07-12 - Quote Totals Clarity

**What was completed:**
Clarified mixed approved/add-on quote totals without changing any pricing formulas.

- Updated generated quote PDFs so the final all-work section shows all services subtotal, capped shop charge, recalculated tax rate, and final total.
- Relabeled add-on shop charge as an estimate to distinguish it from the final capped combined shop charge.
- Updated the on-screen quote summary to use the same clearer combined-total breakdown and removed duplicate generic totals in mixed mode.
