 # Changelog
 
+## 2.3.2 — 2026-10-23
+
+- Harden GitHub Actions CI workflow (`ci.yml`) with job timeouts and comprehensive artifact capture for test results and Playwright HTML reports on failure (closes #40).
+- Add fast developer browser smoke command (`npm run test:browser:smoke`) targeting the Chromium consumer.
+- Document local consumer server ports (`7311`, `7312`, `7313`), browser execution commands, environment failure modes, and automated Axe audit boundaries in `docs/DEVELOPMENT.md`.
+- Conclude Milestone 1 (`[M1] Safe core, accessible widget UI and stable state`).
+
 ## 2.3.1 — 2026-10-23
 
 - Provide runnable Next.js App Router consumer example in `examples/next-app/` with Server Component layout, client boundaries, and route transitions (closes #39).

-`validate` runs typecheck, lint, unit tests and JS/declaration/CSS build. `test:consumers` builds, packs and installs the archive in `.consumers/react18`, `.consumers/react19` and `.consumers/next`, checks ESM/CJS and declarations/SSR, and produces application production builds. Consumers use explicitly selected framework versions; generated install locks reside in disposable `.consumers`. Network access is required for installation, not widget runtime. Browser tests start local ports 7311/7312/7313 and close their servers afterward. Avoid using these ports for unrelated processes. `CI` disables server reuse and is a test-runner environment flag, not a library setting.

+### Local Ports and Consumer Servers
+
+Browser integration tests use local test servers started by Playwright:
+
+- **Port `7311`**: React 18.3.1 consumer application (Vite).
+- **Port `7312`**: React 19.2.0 consumer application with Tailwind CSS 3 (Vite).
+- **Port `7313`**: Next.js 16.2.10 production server (`next start`) testing App Router, Pages Router, and Server Component boundaries.
+
+Avoid using these ports for unrelated background processes. If an `EADDRINUSE` error occurs due to an interrupted run, terminate existing node processes holding these ports.
+
+### Browser Test Commands
+
+- `npm run test:browser`: Executes the full 6-project browser test matrix (React 18 Chromium, React 19 Tailwind Chromium, Next.js App Router Chromium, Firefox, WebKit, and Mobile WebKit emulation).
+- `npm run test:browser:smoke`: Rapid Chromium-only smoke test on the React 18 consumer for fast developer iteration.
+- `CI=1 npm run test:browser`: Disables server reuse in Playwright and forces fresh server lifecycle per run.

-Automated axe results cover the tested widget DOM and criteria tags; they neither certify the host nor cover all assistive-technology behavior.
+### Automated Axe Audits and Human Acceptance
+
+Automated `@axe-core/playwright` checks are executed as part of `tests/browser/widget.spec.ts` against the widget DOM (`[data-arap-ui]`) using WCAG 2.0 A/AA, 2.1 AA, and 2.2 AA rule sets in both light and dark host themes.
+
+- **Scope:** Automated axe results verify that rendered markup, color contrast within the widget panel, native form controls, and ARIA attributes do not produce detectable programmatic violations.
+- **Non-Certification:** Automated test suites do not establish official WCAG conformance or substitute for human accessibility acceptance. Real screen-reader navigation (VoiceOver, NVDA), physical touch devices, browser zoom (200%/400%), and keyboard reviews are mandatory components of accessibility validation.
+
+### Platform and Environment Failure Modes
+
+- **macOS Local Firefox Launch:** Firefox on macOS may fail during Playwright launch with `Could not find profile folder`. The complete Firefox test suite passes in Ubuntu Linux CI.
+- **Port Conflicts:** Ensure ports `7311`, `7312`, and `7313` are free before running `npm run test:browser`. If interrupted, kill existing node processes.
+- **Missing Browser Binaries:** If browser engines are missing, execute `npx playwright install --with-deps chromium firefox webkit`.
