## [Unreleased]

### Added

  columns to suppliers table for paid listing support
- **HTMX live search** — directory search input and filters update results
  via `hx-get` with 300ms debounce; new `/directory/results` endpoint returns
  swappable partial
- **Directory card tiers** — three-tier card design: Pro (green border, logo,
  verified badge, website), Growth (description, blue badge), Free (muted,
  unverified, "Is this your company?" CTA); sticky/featured suppliers pinned
  to top with blue border

  Pro (€399/mo) plan cards with feature lists, boost add-ons grid (Logo,
  Highlight, Verified Badge, Sticky Top, Newsletter Feature), updated FAQ
- **Mandatory form fields** — country, timeline, and stakeholder_type now
  required on quote request form with server-side 422 validation
- **Validation test** — `test_quote_validation_rejects_missing_fields` verifies
  server returns 422 JSON errors for missing mandatory fields

### Changed
- **Nav redesign** — Zillow-style sticky nav with backdrop-blur: demand-side
  links (Planner, Directory) left, supply-side (For Suppliers, Help) after
  separator, Sign In right; removed "Get Started Free" button
- **CTA text sweep** — "Get Matched" → "Get Quotes" across planner, landing,
  and lead forms; removed all "Free" qualifiers from CTAs and badges
- **ROI calculator fix** — realistic cost model: €35K/court (was €25K),
  staff costs, €8/sqm rent (was €4); payback and ROI now based on total
  investment (was equity only); defaults: €40/hr rate, 35% utilization;
  shows ~3.9yr payback, ~26% ROI (was 0.1yr/1255%)
- **Directory route refactor** — shared `_build_directory_query()` helper
  with tier-based SQL ordering (sticky → pro → growth → free → alphabetical)

### Added
- **Supplier directory** — public searchable directory at `/directory/` with 279
  padel court suppliers across 31 countries; FTS5 full-text search, country and
  category filters, pagination, category-colored badges, unclaimed listing model
- **Supplier landing page** — `/suppliers/` marketing page for suppliers: hero,
  how-it-works steps, example lead preview, FAQ, "Claim Your Listing" CTAs
- **Migration 0004** — creates `suppliers` table with FTS5 virtual table,
  content-sync triggers, and seeds 279 suppliers from PadelDirectory.md

  site-wide: royal blue primary (#1D4ED8), green (#16A34A), gold (#D97706);
  elevated cards with soft shadows, rounder corners (rounded-2xl cards,
  rounded-xl buttons/inputs), frosted-glass planner nav, highlighted CTA
  regions with blue-tinted backgrounds, pill-shaped toggle/filter controls,
  polished buttons with colored shadows, stronger hover lift on directory cards

  live supplier/country counts
- **Navbar** — Planner and Directory links now visible for all users (not just
  logged-in); footer updated with Directory and For Suppliers links

  Returns tab CTAs now navigate to wizard step 5 (integrated lead qualifier)
  instead of redirecting to standalone `/leads/quote` form
- **Sitemap** — added `/planner/`, `/directory/`, and `/suppliers/` URLs

### Changed

  (Your Venue → Pricing → Costs → Finance → Get Matched) with live preview
  bar and step navigation; reduces cognitive load from 60 sliders to ~6-15
  per step
- **Integrated lead qualifier** — Step 5 "Get Matched" embeds the supplier
  quote form directly in the planner; auto-fills venue, courts, glass,
  lighting, country, budget from planner state; submits inline via fetch

  and returns `{"ok": true, "heat": "..."}` for inline planner submissions;
  standalone HTML form unchanged

### Added — Phase 0 Round 2: Polish & Country-Specific Calculator
- **Country-specific calculator** — `country` selector (DE/ES/IT/FR/NL/SE/UK/Other) and `permitsCompliance` CAPEX item for Indoor Rent and Outdoor scenarios; country presets auto-adjust permit costs
- **Permits & Compliance** — new CAPEX line item for building permits, noise studies, and regulatory compliance (default €12K for Germany); excluded from Indoor Buy where Planning + Permits already covers this
- **Quote form redesign** — elevated white card on gradient background, green gradient CTA buttons, progress labels (Project/Details/Contact), privacy info box, mandatory consent checkbox
- **Project phase** (replaces location_status options) — 7-stage progression: still searching → location found → converting existing → lease signed → permit not filed → permit pending → permit granted; updated heat scoring

- **Quote URL** — planner now passes `country` parameter to quote form prefill
- **Admin email** — includes stakeholder type and updated field labels

### Added — Phase 0: Ungate & Validate
- **Guest mode planner** — removed auth gate from `/planner/` and `/planner/calculate`; scenarios still require login

- **PDF export CTA** — "Export Business Plan (PDF) — €99" wired to Paddle checkout (`business_plan` price in PADDLE_PRICES)
- **SEO meta tags** — `<meta>` description, og:title, og:description, og:image on planner page
- **Migration 0002** — expands `lead_requests` with 17 new columns for quote qualification flow; makes `user_id` nullable for guest leads
- **Phase 0 test suite** (`tests/test_phase0.py`) — 47 tests covering guest mode, glass/lighting/budget variables, heat scoring, quote submission, schema validation
- Updated Hypothesis strategy in `test_calculator.py` with `budgetTarget`, `glassType`, `lightingType`

### Changed

- Sticky footer bar updated: "Get Builder Quotes" + "Export Business Plan (PDF)" replace old supplier/financing links

### Changed

- Added `.grid-5` CSS helper for 5-column grid layout

### Changed
- **Pico CSS → Tailwind CSS v4** — full design system migration across all templates (except planner, which keeps its own CSS)
  - Standalone Tailwind CLI binary (no Node.js) with `make css-build` / `make css-watch`
  - Court Tech brand theme: navy/charcoal/electric/accent color palette
  - Component classes (`.btn`, `.card`, `.form-input`, `.table`, `.badge`, `.flash`, etc.) in `input.css` for consistent styling
  - Self-hosted Commit Mono font (replaces JetBrains Mono) for monospace data display
  - Docker multi-stage build: CSS compiled in dedicated stage before Python build
- Landing page teaser calculator restyled with Tailwind utilities and brand colors

### Removed
- Pico CSS CDN dependency
- `custom.css` (replaced by Tailwind `input.css` with `@layer components`)
- JetBrains Mono font (replaced by self-hosted Commit Mono)

### Fixed
- Empty env vars (e.g. `SECRET_KEY=`) now fall back to defaults instead of silently using `""` — fixes 500 on every request when `.env` has blank values

### Added
- Comprehensive migration test suite (`tests/test_migrations.py` — 20 tests) covering fresh DB, existing DB, up-to-date DB, idempotent migration, version discovery, `_is_fresh_db`, migration 0001 correctness, and ordering
- Expanded `migrate.py` module docstring documenting the 8-step algorithm, protocol for adding migrations, and design decisions
- Sequential migration system (`migrations/migrate.py`) — tracks applied versions in `_migrations` table, auto-detects fresh vs existing DBs, runs pending migrations in order
- `migrations/versions/0001_rename_ls_to_paddle.py` — first versioned migration (absorbed from `scripts/migrate_to_paddle.py`)
- Server-side financial calculator (`planner/calculator.py`) — ported JS `calc()`, `pmt()`, `calcIRR()` to Python so the full financial model is no longer exposed in client-side JavaScript
- `POST /planner/calculate` endpoint for server-side computation
- Pre-computed initial data (`window.__PADELNOMICS_INITIAL_D__`) injected on page load for instant first render
- Debounced API fetch pattern in `planner.js` with `AbortController` for in-flight request cancellation
- Computing indicator CSS (`.planner-app--computing`) with subtle "computing..." text
- Comprehensive test suite for calculator (`tests/test_calculator.py` — 227 tests) covering all 4 venue/ownership combos, edge cases, and Hypothesis property-based fuzzing
- Comprehensive billing test suite (371 tests total):
  - `tests/conftest.py` — shared fixtures (DB, app, clients, subscriptions, webhook helpers)
  - `tests/test_billing_helpers.py` — unit tests for SQL helpers, feature/limit access, plan determination (60+ tests + parameterized + Hypothesis)
  - `tests/test_billing_webhooks.py` — integration tests for LemonSqueezy webhooks (signature verification, all lifecycle events, Hypothesis fuzzing)
  - `tests/test_billing_routes.py` — route tests (pricing, checkout, manage, cancel, resume, subscription_required decorator)
  - Added `hypothesis>=6.100.0` and `respx>=0.22.0` to dev dependencies for property-based testing and httpx mocking
  - **Factored into Copier template** — all billing tests now generate as `.jinja` templates with provider-specific conditionals for Stripe, Paddle, and LemonSqueezy
- GitLab CI/CD pipeline (`.gitlab-ci.yml`) — runs pytest + ruff on master/MRs, auto-deploys on master
- Blue-green deployment with Docker Compose profiles (`docker-compose.prod.yml`, `deploy.sh`)
  - nginx router on port 5000 proxies to active blue/green slot
  - Zero-downtime: new slot health-checked before traffic switch
  - Automatic rollback on failed health check

### Removed
- `scripts/migrate_to_paddle.py` — superseded by `versions/0001_rename_ls_to_paddle.py`

### Changed
- `planner.js` no longer contains `calc()`, `pmt()`, or `calcIRR()` functions — computation moved server-side
- `render()` split into `render()` (tab switching + schedule calc) and `renderWith(d)` (DOM updates from data)
- Tab switching now renders from `_lastD` cache (instant, no API call)
- Slider input triggers 200ms debounced server call instead of synchronous client-side calc
