Merge branch 'main' into fix/deploy-dev-kustomize-install-clean

CTO review feedback: kustomize edit set image operates on the
kustomization.yaml in the current working directory. Since the
target file is at infra/apps/overlays/dev/kustomization.yaml, the
step must cd there before running kustomize.

-# CartSnitch
+# 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`.

-# 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 |
-|---|-----------|------------|
-| E1 | CI pipeline passes on the merged commit (lint, type-check, unit tests, build) | GitHub Actions (automated) |
-| E2 | Docker image is built and pushed to GHCR with a CalVer tag | GitHub Actions (automated) |
-| E3 | Dev environment is deployed and accessible at `cartsnitch.dev.farh.net` | Flux reconciliation + health check |
-| E4 | All Playwright E2E tests pass in CI | GitHub Actions (automated) |
-| E5 | No open S1/S2 defects from previous UAT cycle | Checkout Charlie (manual check) |
-| E6 | PR has been reviewed and approved by QA (Checkout Charlie) and CTO (Savannah Savings) | GitHub PR approvals |
-| E7 | PR has been merged to main by CEO (Coupon Carl) | GitHub merge event |
-| E8 | Acceptance criteria for the feature/change are documented in the Paperclip issue | Checkout Charlie (manual check) |
-
-**If any entry criterion is not met**, UAT is blocked. Checkout Charlie must comment on the Paperclip issue specifying which criteria failed and assign back to the responsible party.
-
----
-
-## 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 |
