 All data comes from the CartSnitch API gateway (`cartsnitch/api`). Base URL configured via environment variable `VITE_API_URL`.

- JWT auth: store access token in memory (not localStorage), refresh token in httpOnly cookie if possible, or secure storage.
+- **Authentication via Better-Auth** (`auth/` service). Sessions are managed via httpOnly cookies — no tokens in localStorage or memory.
+  - Auth service URL configured via `VITE_AUTH_URL` (default: `http://localhost:3001`)
+  - Frontend uses `better-auth/react` client for sign-in, sign-up, sign-out, and `useSession()` hook
+  - API gateway validates sessions by querying the shared `sessions` table in Postgres
+  - Both cookie-based and Bearer token auth are supported (cookies for web, Bearer for API clients)
 - TanStack Query handles caching, background refetching, and optimistic updates.
- API client should handle 401 responses by attempting token refresh before retrying.
+- API client sends `credentials: 'include'` on all requests to forward session cookies.

-# CartSnitch Monorepo
-
-CartSnitch is a self-hosted grocery price intelligence platform. This repo consolidates the core services and the flagship frontend PWA.
-
-## Services
-
-| Directory | Service | Purpose |
-|-----------|---------|---------|
-| `/` (root) | **Frontend** | React 18 PWA — mobile-first price intelligence UI |
-| `api/` | **API Gateway** | FastAPI — frontend-facing REST API |
-| `common/` | **Common** | Shared Python models, schemas, Alembic migrations |
-| `receiptwitness/` | **ReceiptWitness** | Purchase ingestion via retailer scrapers |
-
-## Quick Start
-
-### Frontend (root)
-
-```bash
-npm install
-npm run dev        # http://localhost:5173
-npm run build      # production build
-npm run test       # unit tests (Vitest)
-```
-
-### Python Services
-
-Each Python service uses [uv](https://github.com/astral-sh/uv) and has its own `pyproject.toml`:
-
-```bash
-cd api             # or common / receiptwitness
-uv sync
-uv run pytest
-```
-
-## Development Workflow
-
- **Never push directly to main.** Always open a PR from a feature branch.
- Branch naming: `feature/<description>` or `fix/<description>`
- Conventional commits: `feat:`, `fix:`, `refactor:`, `docs:`, `chore:`
-
-## Architecture
-
-For full details see [CLAUDE.md](./CLAUDE.md) or the per-service `CLAUDE.md` in each subdirectory.
-
-CartSnitch is a polyrepo-style monorepo: each service can be built and deployed independently, but sharing code between `common/` and the other Python services is done via local path dependencies in `pyproject.toml`.

+
+# Understanding Shrinkflation: A Consumer's FAQ
+
+You notice it at the grocery store: the cereal box looks smaller. The chip bag seems to have less air in it. The pasta salad you loved now fits less in the container. But the price is the same — or higher.
+
+That is shrinkflation. Here is what you need to know.
+
+---
+
+## What Is Shrinkflation?
+
+Shrinkflation is the practice of reducing the size or quantity of a product while keeping the price the same — or raising it. The per-unit cost increases without the packaging change being obvious at first glance.
+
+It is different from inflation. Inflation raises prices for the same product. Shrinkflation keeps the price the same for a smaller product. Both cost you more per ounce, per gram, or per use.
+
+---
+
+## Is Shrinkflation Legal?
+
+Yes. Shrinkflation is legal in the US and most markets. Manufacturers are required to state the net weight or count on the packaging, but they are not required to announce when a product gets smaller. There is no federal regulation specifically banning shrinkflation.
+
+Some regulators have begun studying the practice, and there have been proposals for mandatory price-per-unit labeling at the shelf level, but no binding rules exist as of 2026.
+
+---
+
+## What's an Example of Shrinkflation?
+
+Common examples from 2020–2025:
+
+- **Cereal:** Family-size boxes shrank from 20 oz to 18 oz to 16 oz while prices stayed at $4.99–$5.99
+- **Crackers:** Standard sleeve count dropped from 4 to 3 packs while shelf price remained constant
+- **Yogurt:** Multipacks reduced from 6 oz cups to 5.3 oz cups
+- **Paper towels:** Roll count dropped from 12 to 10 while price stayed the same
+- **Dish soap:** Bottle volumes shrank from 24 oz to 20 oz
+
+In every case, the per-unit cost increased even when the shelf price did not change — or changed less than the size reduction warranted.
+
+---
+
+## How Much Does Shrinkflation Cost the Average Family?
+
+Estimates vary by shopping habits and product categories. CartSnitch analysis of manufacturer packaging data suggests the average US household spends an additional $80–$120 per year on cereals alone due to shrinkflation. Across all categories — snacks, dairy, household goods, beverages — total hidden costs per household are estimated at $300–$500 per year.
+
+These figures are directional estimates based on publicly available manufacturer packaging data, not CartSnitch production data.
+
+---
+
+## Why Do Brands Use Shrinkflation?
+
+Brands use shrinkflation because consumers notice price increases more than package size decreases. A $5 cereal box going to $5.50 is visible and may cause consumers to switch to competitors. A $5 cereal box shrinking from 18 oz to 15 oz at the same price is rarely noticed until someone like CartSnitch tracks the unit price.
+
+Shrinkflation is most common in products where:
+- Brand loyalty is high (consumers repurchase without checking alternatives)
+- Unit prices are not prominently displayed
+- Size reductions are modest (5–15%)
+- The product is purchased regularly
+
+---
+
+## How Do I Detect Shrinkflation?
+
+Three ways to catch shrinkflation before you overpay:
+
+1. **Track unit prices** — Divide the shelf price by the size (oz, g, count). If the unit price goes up but the product looks the same, you are being shrunk.
+2. **Compare across brands** — A competing brand may offer more product for the same or lower price.
+3. **Use CartSnitch** — CartSnitch monitors unit prices on your tracked products and alerts you when a product you buy regularly gets smaller or more expensive.
+
+---
+
+## Does Shrinkflation Affect Store Brands Too?
+
+Yes. Store brands (private label) also engage in shrinkflation, though they tend to do so less aggressively than name brands. National brands rely more heavily on shrinkflation because they cannot compete on price as easily as store brands do.
+
+---
+
+## Is There a Campaign or Movement Against Shrinkflation?
+
+Consumer advocacy groups have lobbied for:
+- Mandatory unit price display at shelf level
+- Required advance notice when product sizes change
+- Clear "size changed" labels on packaging
+
+CartSnitch is built to give consumers the data they need to make informed decisions — even before regulation catches up.
+
+---
+
+## How Is Shrinkflation Different From Price Gouging?
+
+Shrinkflation is a gradual, product-level practice by manufacturers. Price gouging is typically a retailer or seller raising prices sharply during a supply crisis or emergency. Both harm consumers, but they are distinct practices.
+
+Price gouging is illegal in many states during declared emergencies. Shrinkflation is legal year-round.
+
+---
+
+## Summary
+
+Shrinkflation is how brands quietly raise prices by giving you less product for the same money. It is legal, common, and affects the average family by hundreds of dollars per year. The only defense is tracking unit prices — and CartSnitch does that automatically.

+# CartSnitch UAT Runbook v1
+
+**Version:** 1.0
+**Author:** Savannah Savings, CTO
+**Date:** 2026-03-30
+**Effective:** Immediately upon Phase 1 completion
+
+---
+
+## 1. Defect Severity Classification
+
+Every defect discovered during UAT **must** be classified by severity and priority before triage.
+
+### Severity Levels
+
+| Severity | Definition | Examples |
+|----------|-----------|----------|
+| **S1 — Critical** | Blocks all users from completing a core journey. System is down, data is lost, or security is breached. | Login page crashes for all users; purchase data deleted; auth tokens exposed in response |
+| **S2 — High** | Blocks a major user flow for a significant portion of users. Core feature is broken but workarounds may exist. | Registration fails for email addresses with `+` character; price alerts never trigger; store comparison shows wrong prices |
+| **S3 — Medium** | Feature is degraded but usable. User can complete the journey with friction. | Date formatting shows raw ISO string instead of friendly date; slow page load (>5s) on product detail; search results not sorted correctly |
+| **S4 — Low** | Cosmetic issue, minor UI inconsistency, or edge case with minimal user impact. | Button text truncated on narrow screens; extra whitespace in footer; tooltip shows on hover but not on focus |
+
+### Priority Levels
+
+Priority determines **when** the defect must be fixed. Priority is set by the CTO based on severity, business impact, and sprint capacity.
+
+| Priority | SLA | When to Use |
+|----------|-----|------------|
+| **P0 — Fix Now** | Triage within 1 hour, fix deployed within 4 hours | S1 defects, any security vulnerability, data integrity issues |
+| **P1 — Fix This Sprint** | Triage within 4 hours, fix in current sprint | S2 defects blocking upcoming release, S1 defects with viable workaround |
+| **P2 — Fix Next Sprint** | Triage within 24 hours, scheduled for next sprint | S3 defects, S2 defects with easy workarounds |
+| **P3 — Backlog** | Triage within 48 hours, prioritized against backlog | S4 defects, minor improvements, nice-to-haves |
+
+### Defect Report Template
+
+Every defect filed during UAT must include:
+
+```
+**Title:** [Short description]
+**Severity:** S1/S2/S3/S4
+**Priority:** P0/P1/P2/P3 (set by CTO at triage)
+**Journey:** [Which user journey — J1 through J10]
+**Environment:** [Dev / Prod, deployed image tag]
+**Steps to Reproduce:**
+1. Navigate to ...
+2. Click ...
+3. Enter ...
+**Expected Result:** ...
+**Actual Result:** ...
+**Screenshots/Logs:** [Attach or link]
+**Browser/Device:** [e.g., Chromium 124, mobile viewport 390x844]
+```

+
+## 2. UAT Entry Criteria
+
+UAT **must not begin** until ALL of the following are satisfied. Checkout Charlie verifies these before opening the UAT gate.
+
+| # | Criterion | Verified By |
+|---|-----------|------------|

+
+## 3. UAT Exit Criteria
+
+UAT is **complete** only when ALL of the following are satisfied. Rollback Rhonda verifies these before signing off.
+
+| # | Criterion | Verified By |
+|---|-----------|------------|
+| X1 | All 10 critical user journeys (J1-J10) have been executed | Rollback Rhonda (full regression) |
+| X2 | Zero open S1 (Critical) defects | Defect tracker |
+| X3 | Zero open S2 (High) defects, OR CTO has granted a documented exception | Defect tracker + CTO sign-off |
+| X4 | All S3/S4 defects are logged and triaged (not necessarily fixed) | Defect tracker |
+| X5 | 100% test execution rate -- every test case was run, none skipped | Rollback Rhonda's UAT report |
+| X6 | Accessibility scan (axe-core) reports zero critical violations | Automated in E2E suite |
+| X7 | Lighthouse performance score >= 50, accessibility score >= 90 | Lighthouse CI |
+| X8 | Written sign-off from Rollback Rhonda confirming all criteria met | Paperclip comment on issue |
+
+**If any exit criterion is not met**, the release is blocked. Rollback Rhonda must:
+1. File defects for all failures using the Defect Report Template above.
+2. Comment on the Paperclip issue specifying which exit criteria failed.
+3. Assign back to CTO for triage and redistribution.
+
+---
+
+## 4. UAT Execution Procedure
+
+### 4.1 Pre-UAT (Checkout Charlie)
+
+1. Verify all entry criteria (E1-E8) are met.
+2. Comment on the Paperclip issue: "UAT gate open -- all entry criteria verified."
+3. Assign to Rollback Rhonda with status todo.
+
+### 4.2 UAT Execution (Rollback Rhonda)
+
+1. **Full regression run** -- execute ALL 10 user journeys against cartsnitch.dev.farh.net. No partial runs. No exceptions.
+2. For each journey, verify:
+   - All interactive elements respond correctly (buttons, forms, links, toggles)
+   - State transitions are correct (auth state, data mutations, navigation)
+   - Error states are handled gracefully (invalid input, network failures)
+   - Accessibility scan passes (axe-core integrated in Playwright)
+3. Log results for each journey: PASS / FAIL with details.
+4. File defects immediately for any failures.
+5. Complete the UAT report with execution results.
+
+### 4.3 Post-UAT Sign-Off
+
+1. If all exit criteria (X1-X8) are met:
+   - Rollback Rhonda posts sign-off comment: "UAT PASSED -- all exit criteria met."
+   - Production promotion is automated via Flux on UAT pass.
+2. If any exit criterion fails:
+   - Rollback Rhonda posts failure comment with specific failures.
+   - CTO triages defects and redistributes to engineers.
+   - After fixes are merged, UAT restarts from 4.1 (full cycle).
+
+---
+
+## 5. Critical User Journeys Reference
+
+| ID | Journey | Key Interactions |
+|----|---------|-----------------|
+| J1 | Registration -> Login -> Dashboard | Form submission, auth state, redirect |
+| J2 | Login -> Browse Products -> View Detail -> Price Chart | Search, navigation, data visualization |
+| J3 | Login -> Purchases -> Purchase Detail -> Product Link | List navigation, detail view, cross-linking |
+| J4 | Login -> Connect Store Account -> Verify Connection | OAuth flow, external integration |
+| J5 | Login -> Create Price Alert -> View -> Delete Alert | CRUD operations, confirmation dialogs |
+| J6 | Login -> Browse Coupons -> Copy Code | Clipboard interaction, toast feedback |
+| J7 | Login -> Settings -> Toggle Preferences -> Sign Out | Checkbox toggles, theme switch, session termination |
+| J8 | Login -> Store Comparison -> Compare Prices | Data comparison, sorting, price display |
+| J9 | Forgot Password Flow | Email input, validation, redirect |
+| J10 | Unauth Access -> Redirect to Login | Route protection, redirect behavior |
