feat(ui): v0.2.0 — URL routing, blank slate, rich empty states, 225 tests

Admin Dashboard:
- URL routing via History API (/, /services, /dns, /tls, /servers, /routing)
- Interactive blank slate topology visualization for first-time users
- Rich per-view empty states with feature pills and CLI commands
- 225 tests across 17 files, 97%+ coverage (vitest + RTL + happy-dom)
- Docker-based UI dev with hot reload (make ui)

Infrastructure:
- Node 22 to 24 LTS, FastAPI 0.135.3, Uvicorn 0.44.0, Pydantic 2.12.5
- TLS API path fix (/api/tls/certs -> /api/tls)
- TLS page title fix (TlsCerts -> Certificates)
- ShellCheck fix in lib/tls.sh (SC2155)
- bats test fix for tls_ensure_ca exit code

Repository polish:
- All docs renamed to lowercase kebab-case (8 files)
- Cross-references updated across 17 docs
- docs/README.md index following capsule pattern
- CONTRIBUTING.md rewritten with UI/Docker/testing workflow
- NOTICE expanded with UI dependencies
- CI workflow: added UI test job, Node 24, Python 3.13 for pip-audit

@@ -5,6 +5,25 @@ All notable changes to this project will be documented in this file.

+## [0.2.0] - 2026-04-07
+
+### Added
+
+- **URL routing.** Each view has a dedicated URL (`/`, `/services`, `/dns`, `/tls`, `/servers`, `/routing`). Deep links, bookmarks, and browser back/forward all work. History API integration in the Zustand store with popstate listener.
+- **Blank slate experience.** Interactive SVG topology visualization with animated data packets, 5 capability cards, principles strip, and step-by-step getting started flow. Shown when no services, certs, DNS, or servers are registered.
+- **Rich per-view empty states.** Each view (Services, DNS, TLS, Servers, Routing) shows a section-colored empty state with icon, feature pills, CLI command, and navigation action via the shared `ViewBlankSlate` component.
+- **Test suite.** 225 tests across 17 files covering stores, API client, formatters, all shared components, and all 6 views. 97.3% statement coverage, 97.2% line coverage. Vitest + React Testing Library + happy-dom.
+- **Docker-based UI development.** `make ui` runs Vite inside a Node 24 container with mounted source for hot reload. No local Node.js required.
+
+### Changed
+
+- **Node 22 to Node 24 LTS** in Dockerfile and Makefile `ui` target.
+- **Python dependencies updated:** FastAPI 0.115.12 to 0.135.3, Uvicorn 0.34.3 to 0.44.0, Pydantic 2.11.4 to 2.12.5. Pydantic 2.12.5 ships prebuilt `pydantic-core` wheels for Python 3.14 (the prior version required Rust compilation).
+- **Documentation restructured.** All doc filenames renamed from UPPERCASE to lowercase kebab-case. Cross-references updated across all 17 docs. New `docs/README.md` index following the capsule pattern.
+- **TLS API paths fixed.** Frontend was calling `/api/tls/certs` but server endpoint is `/api/tls`. Aligned all TLS API paths.
+- **TLS page title.** "TLS TlsCerts" corrected to "TLS Certificates".
+- **`@vitest/coverage-v8`** added as devDependency for coverage reporting.

-Open a GitHub issue with:
-- A clear title describing the problem
-- Steps to reproduce
-- Expected vs. actual behavior
-- Your OS, bash version, Caddy version, and dnsmasq version
+## Types of Contributions
 
-### Submitting Changes
+**Shell scripts.** Bug fixes, new commands, lib module improvements. Must pass shellcheck and bats tests.
 
-1. Fork the repository
-2. Create a feature branch (`git checkout -b feature/my-change`)
-3. Make your changes
-4. Run the test suite: `make test`
-5. Commit with a clear message
-6. Open a pull request
+**Admin UI.** React components, new views, design system updates. Must pass vitest and typecheck.
 
-### Pull Request Guidelines
+**API server.** New endpoints, performance, validation. Must match shell command behavior.
 
-- Keep PRs focused on a single change
-- Include tests for new functionality
-- Update documentation if behavior changes
-- Follow the existing code style (see below)
+**Documentation.** Guides, examples, compliance mappings. Must be verified against code.
 
-## Code Style
+## Getting Started
 
-### Shell Scripts
+```bash
+# Clone and enter the repo
+git clone https://github.com/quantumpipes/conduit.git
+cd conduit
 
-- `set -euo pipefail` at the top of every script
-- Functions documented with a comment block explaining purpose and parameters
-- Use `local` for all function variables
-- Validate inputs at function boundaries
-- Never use `eval`
-- Use `$(command)` instead of backticks
-- Quote all variable expansions: `"$var"` not `$var`
-- File permissions: 600 for certificates and keys, 700 for directories
+# Start the full stack in Docker
+make dev
+
+# Or start just the admin UI with hot reload
+make ui
+```
+
+## Running Tests
+
+```bash
+# Shell tests (bats-core)
+make test              # All tests
+make test-unit         # Unit tests only
+make test-integration  # Integration tests only
+make test-smoke        # Smoke tests (requires running Conduit)
 
-### Caddy Configuration
+# Admin UI tests (vitest + React Testing Library)
+make test-ui           # 225 tests, 97%+ coverage
 
-- Use Caddyfile format (not JSON) for readability
-- One site block per logical service
-- Always include health check endpoints
-- Use internal TLS (never self-signed hacks)
+# Type-check the UI
+make ui-typecheck
 
-### dnsmasq Configuration
+# Everything
+make check
+```
 
-- One record type per configuration line
-- Comment every non-obvious record
-- Use `address=` for service discovery, `server=` for upstream forwarding
+## Submitting Changes
 
-### Testing
+1. Fork the repository
+2. Create a feature branch (`git checkout -b feat/my-change`)
+3. Make your changes
+4. Run the relevant test suite (`make test` and/or `make test-ui`)
+5. Commit with a [conventional commit](https://www.conventionalcommits.org/) message
+6. Open a pull request
 
-- Tests use [bats-core](https://github.com/bats-core/bats-core)
-- Follow AAA pattern: Arrange, Act, Assert
-- Tests must be deterministic and isolated (use `$BATS_TMPDIR`)
-- Test both success paths and error paths
-- New lib functions require unit tests
+Keep PRs focused on a single change. Include tests for new functionality. Update documentation if behavior changes.
 
-### Documentation
+## Code Standards
 
-- Update README.md if adding commands or configuration
-- Comments in code should explain "why", not "what"
+### Shell Scripts
 
-## Architecture Principles
+- `set -euo pipefail` at the top of every script
+- `local` for all function variables
+- Quote all variable expansions: `"$var"` not `$var`
+- Validate inputs with strict regexes (`^[a-zA-Z0-9_-]+$`)
+- Never use `eval`
+- Use `jq` for JSON (no sed/awk on JSON)
+- Run `shellcheck` on all `.sh` files
 
-- **Air-gap compatible:** No features requiring internet connectivity
-- **Configurable:** All defaults overridable via environment variables
-- **Health-aware:** Every routed service must have a health check
-- **Secure by default:** Internal TLS everywhere, strict input validation
-- **Observable:** All state changes logged with structured output
+### Python (server.py)
 
-## Testing Your Changes
+- Type hints on all function signatures
+- `subprocess.run` with `capture_output=True` and `timeout`
+- Never `shell=True`
+- `Path` objects for file paths
 
-```bash
-# Install bats-core
-git clone https://github.com/bats-core/bats-core.git
-cd bats-core && sudo ./install.sh /usr/local
+### TypeScript (Admin UI)
 
-# Run all tests
-make test
+- Strict mode enabled
+- All data types in `ui/src/lib/types.ts`
+- Semantic color tokens from theme (no hardcoded hex)
+- Tests colocated with source (`*.test.tsx` next to `*.tsx`)
+- AAA pattern (Arrange, Act, Assert)
 
-# Run specific test tiers
-make test-unit
-make test-integration
-make test-smoke
-```
