🐛 fix(bdd): exclude @v2 scenarios from default BDD test runs

The 4 v2 scenarios in greet.feature require special config (FEATURE=greet GODOG_TAGS=@v2) to enable the v2 endpoint via shouldEnableV2(). Without that config, all v2 scenarios fail with "v2 endpoint not available". Two fixes: 1. Tag the 3 untagged v2 scenarios with @v2 @api (one already had it, others were missing tags) 2. Extend DEFAULT_TAGS in run-bdd-tests.sh to exclude @v2 This makes the default BDD test run pass on CI without v2 setup. v2 scenarios can still be run explicitly with: FEATURE=greet GODOG_TAGS=@v2 go test ./features/greet/... Companion to PR #26 (BDD_SCHEMA_ISOLATION) - both target CI green. 🤖 Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

 # ADR 0026: Composite Info Endpoint vs Separate Calls
 **Status:** Implemented (2026-05-05 — PR pending)
 ## Context
 The application currently exposes several endpoints that provide system information:
 - `/api/version` - returns version, commit, build date, Go version (cached 60s)
 - `/api/health` - returns `{"status":"healthy"}` (simple liveness)
 - `/api/healthz` - returns rich health info: status, version, uptime_seconds, timestamp
 - `/api/ready` - returns readiness with connection details
 Frontend components like `HealthDashboard` currently call `/api/healthz` to display server info. However, there is a need for a **composite endpoint** that aggregates:
 1. Version information (from `/api/version`)
 2. Build metadata (commit hash, build date)
 3. Uptime information (from `/api/healthz`)
 4. Cache status (enabled/disabled)
 5. Health status
 This raises an architectural question: **Should we create a new composite `/api/info` endpoint, or should frontend components make multiple separate API calls?**
 ### The Problem with Separate Calls
 If the frontend makes individual calls to `/api/version`, `/api/healthz`, and checks cache config separately:
 1. **Multiple network requests**: 3-4 HTTP round trips per page load
 2. **Inconsistent data**: Responses may come from different moments in time
 3. **No caching coordination**: Each endpoint has its own cache key and TTL
 4. **Complex frontend logic**: Need to merge data from multiple sources
 5. **Poor user experience**: Slower page loads, multiple loading states
 ### Current State Analysis
 | Endpoint | Data Provided | Cache TTL | Use Case |
 |----------|---------------|-----------|----------|
 | `/api/version` | version, commit, built, go | 60s | Version info |
 | `/api/healthz` | status, version, uptime_seconds, timestamp | None | K8s probes, health dashboard |
 | `/api/health` | status: "healthy" | None | Simple liveness |
 | `/api/ready` | ready, connections, reason | None | Readiness probes |
 The `/api/healthz` endpoint already combines some data (status + version + uptime + timestamp), but it:
 - Doesn't include commit_short
 - Doesn't include build_date separately
 - Doesn't include cache_enabled
 - Is not cached
 - Has Kubernetes-specific field naming (`healthz`)
 ## Decision Drivers
 * **Performance**: Minimize network round trips for frontend
 * **Consistency**: All data should reflect the same point-in-time
 * **Maintainability**: Single source of truth for system info
 * **Caching**: Reuse existing cache infrastructure (ADR-0022)
 * **API Design**: Follow REST principles and existing patterns
 * **Backward Compatibility**: Existing endpoints must remain unchanged
 ## Considered Options
 ### Option 1: Composite `/api/info` Endpoint (Chosen)
 Create a new endpoint that aggregates all required data in a single call.
 **Pros:**
 - ✅ Single network request for frontend
 - ✅ Consistent point-in-time data
 - ✅ Can leverage existing cache infrastructure with key `info:json`
 - ✅ Follows existing pattern of `/api/version` caching
 - ✅ Clean API design - one endpoint, one purpose
 - ✅ Reduces frontend complexity
 - ✅ Better UX - faster page loads
 - ✅ Aligns with ADR-0022 cache strategy (reusable cache key pattern)
 **Cons:**
 - ⚠️ Duplicates some data from `/api/healthz` and `/api/version`
 - ⚠️ Requires new endpoint implementation
 - ⚠️ Need to maintain consistency if source endpoints change
 ### Option 2: Frontend Aggregation with Multiple Calls
 Frontend makes separate calls to `/api/version`, `/api/healthz`, and introspects config.
 **Pros:**
 - ✅ No backend changes required
 - ✅ Uses existing endpoints
 **Cons:**
 - ❌ Multiple network requests (3-4 round trips)
 - ❌ Inconsistent data timing
 - ❌ Complex error handling in frontend
 - ❌ Poor UX - multiple loading states, slower
 - ❌ Each endpoint has different caching behavior
 - ❌ Violates DRY - same data fetched multiple times
 ### Option 3: Extend `/api/healthz` Endpoint
 Add `commit_short`, `build_date`, and `cache_enabled` fields to existing `/api/healthz`.
 **Pros:**
 - ✅ Reuses existing endpoint
 - ✅ Single request
 **Cons:**
 - ❌ Breaks backward compatibility (response schema change)
 - ❌ `/api/healthz` is Kubernetes-focused (naming convention)
 - ❌ Not cached currently
 - ❌ Mixes health probe concerns with version info
 - ❌ Violates single responsibility
 ### Option 4: GraphQL / Query Parameters
 Allow clients to specify which fields they want via query parameters.
 **Pros:**
 - ✅ Flexible - clients get exactly what they need
 - ✅ Single endpoint
 **Cons:**
 - ❌ Overkill for this use case
 - ❌ Not consistent with existing REST API design
 - ❌ Complex implementation
 - ❌ Not aligned with project architecture (Chi router, REST style)
 ## Decision Outcome
 **Chosen: Option 1 - Composite `/api/info` Endpoint**
 We will implement a new `GET /api/info` endpoint that returns a JSON object with all required fields in a single call. This endpoint will:
 1. Aggregate data from existing sources (`version` package, `config`, server uptime)
 2. Be cached using the existing cache service with key `info:json`
 3. Use TTL from `config.cache.default_ttl_seconds` (consistent with ADR-0022)
 4. Return `X-Cache: HIT/MISS` headers for debugging
 5. Follow existing Go handler patterns from `pkg/server/server.go`
 ### Response Schema
 ```json
 {
  "version": "1.4.0",
  "commit_short": "a3f7b2c1",
  "build_date": "2026-05-04T08:00:00Z",
  "uptime_seconds": 1234,
  "cache_enabled": true,
  "healthz_status": "healthy"
 }
 ```
 ### Rationale
 1. **Performance**: Single HTTP request instead of 3-4 separate calls
 2. **Consistency**: All data reflects the same moment in time
 3. **Caching**: Leverages existing cache infrastructure (ADR-0022) with predictable key pattern
 4. **API Design**: Clean, RESTful endpoint with single responsibility
 5. **Maintainability**: Clear separation of concerns - info aggregation is a distinct use case
 6. **Backward Compatibility**: Existing endpoints remain unchanged
 7. **Frontend Simplicity**: Reduces complexity and improves UX
 ### Cache Strategy
 Following ADR-0022 pattern:
 - Cache key: `info:json` (consistent with `version:format` pattern)
 - TTL: `config.cache.default_ttl_seconds` (default 300 seconds)
 - Cache service: `pkg/cache/cache.go` InMemoryService
 - Headers: `X-Cache: HIT` or `X-Cache: MISS`
 This allows the endpoint to be fast even under load, while maintaining data freshness.
 ## Consequences
 ### Positive
 1. **Improved frontend performance**: Single request instead of multiple
 2. **Better UX**: Faster page loads, simpler loading states
 3. **Consistent data**: All fields reflect the same point-in-time
 4. **Cache efficiency**: Reuses existing cache infrastructure
 5. **Clean separation**: Info endpoint handles aggregation, source endpoints unchanged
 6. **Easy to test**: Single endpoint with predictable response
 ### Negative
 1. **Data duplication**: Some fields appear in multiple endpoints
 2. **Maintenance burden**: If source data changes, endpoint must be updated
 3. **New endpoint**: Increases API surface area (though minimal)
 ### Mitigation
 1. Data duplication is acceptable - it's read-only system info
 2. Source the data from the same packages/functions used by other endpoints
 3. The new endpoint has a clear, focused purpose

 # API endpoints
 Reference document for all HTTP endpoints exposed by `dance-lessons-coach` server. The authoritative source is the swag-generated Swagger UI at `/swagger/index.html` (served by the Go binary). This markdown is the human-readable index, intentionally short — when in doubt, run the server and open Swagger.
 ## Conventions
 - All paths under `/api/` (no other prefix is used)
 - Versioned API under `/api/v1/<resource>` and `/api/v2/<resource>` (cf. ADR-0010 v2 feature flag)
 - System / Health / Version endpoints at root (`/api/<endpoint>`, no version)
 - Admin endpoints under `/api/admin/<action>` (require master admin password header)
 - Response Content-Type: `application/json` unless documented otherwise
 - Error envelope: `{"error":"<code>","message":"<text>"}` (HTTP 4xx/5xx)
 ## System endpoints (no auth)
 | Method | Path | Purpose | Cf. |
 |---|---|---|---|
 | GET | `/api/health` | Liveness check (legacy, returns `{"status":"healthy"}`) | `pkg/server/server.go` |
 | GET | `/api/healthz` | **Kubernetes-style** rich health: status / version / uptime_seconds / timestamp | PR #20 — handler with swag `@Router /healthz [get]` |
 | GET | `/api/ready` | Readiness check (DB connection + service deps) | `pkg/server/server.go handleReadiness` |
 | GET | `/api/version` | Version info (cached 60s, since PR #29) | `pkg/server/server.go handleVersion` |
 | GET | `/api/info` | **Composite info aggregator**: version / commit_short / build_date / uptime_seconds / cache_enabled / healthz_status. Cached when cache is enabled (X-Cache: HIT/MISS header) | ADR-0026 — `pkg/server/server.go handleInfo` |
 `/api/info` body schema (`InfoResponse`):
 ```json
 {
  "version": "1.0.0",
  "commit_short": "abc12345",
  "build_date": "2026-05-05",
  "uptime_seconds": 1234,
  "cache_enabled": true,
  "healthz_status": "healthy"
 }
 ```
 Use `/api/info` from a frontend footer or status page when you need version + uptime + cache state in a single round trip. The composite design avoids 3-4 chatty calls (`/version`, `/healthz`, `/ready`) when only a snapshot is needed.
 `/api/healthz` body schema (`HealthzResponse`):
 ```json
 {
  "status": "healthy",
  "version": "1.4.0",
  "uptime_seconds": 1234,
  "timestamp": "2026-05-04T08:00:00Z"
 }
 ```
 Use `/api/healthz` for kubelet liveness probes — richer than `/api/health` and stable.
 ## Admin endpoints (require X-Admin-Password header)
 | Method | Path | Purpose | Cf. |
 |---|---|---|---|
 | POST | `/api/admin/cache/flush` | Flush the entire in-memory cache. Returns `{"flushed":true,"items_flushed":N,"timestamp":"..."}` (200) or `{"error":"unauthorized"}` (401) or `{"error":"cache_disabled"}` (503) | PR #29 — `pkg/server/server.go handleAdminCacheFlush` |
 Auth: header `X-Admin-Password: <master-password>` (matches `auth.admin_master_password` in config / `DLC_AUTH_ADMIN_MASTER_PASSWORD` env var). Default `admin123` for local dev — **change in production**.
 ## v1 API (auth + greeting)
 Mounted at `/api/v1/...` with the rate-limit middleware (cf. ADR-0022 Phase 1, since PR #22). Cached responses on greet (since PR #29).
 ### Auth (`/api/v1/auth/...`)
 | Method | Path | Purpose |
 |---|---|---|
 | POST | `/api/v1/auth/register` | User registration |
 | POST | `/api/v1/auth/login` | Login with username + password, returns JWT |
 | POST | `/api/v1/auth/validate` | Validate a JWT token |
 | POST | `/api/v1/auth/password-reset/request` | Request password reset (admin-flagged users only) |
 | POST | `/api/v1/auth/password-reset/complete` | Complete password reset |
 JWT secret rotation policies: cf. ADR-0021 + JWT secrets endpoints under `/api/v1/admin/jwt/secrets` (admin-only).
 ### Greet (`/api/v1/greet/...`)
 | Method | Path | Purpose |
 |---|---|---|
 | GET | `/api/v1/greet?name=X` | Greeting (cached per name 60s, header `X-Cache: HIT/MISS`) |
 | GET | `/api/v1/greet/{name}` | Greeting (path param variant, same caching) |
 ### Admin under v1 (`/api/v1/admin/...`)
 JWT secret management endpoints. Cf. swag annotations in handlers + features/jwt/ BDD scenarios for the exact contract.
 ## v2 API
 Enabled via `api.v2_enabled` config (cf. ADR-0010 v2 feature flag).
 | Method | Path | Purpose |
 |---|---|---|
 | POST | `/api/v2/greet` | v2 greeting (JSON body, more validation) |
 ## Swagger UI
 Served at `/swagger/index.html` (and `/swagger/doc.json` for the embedded spec). Always reflects what the running binary exposes — when in doubt, prefer Swagger over this markdown.

 # BDD test environment
 Environment variables and tooling specific to running BDD scenarios locally and in CI. Companion to [BDD_GUIDE.md](BDD_GUIDE.md) (which covers the BDD authoring workflow itself).
 ## Required env vars (database connection)
 The BDD test server needs a Postgres instance reachable via:
 | Var | Default | Notes |
 |---|---|---|
 | `DLC_DATABASE_HOST` | `localhost` | Host of the Postgres instance |
 | `DLC_DATABASE_PORT` | `5432` | |
 | `DLC_DATABASE_USER` | `postgres` | Test-only credentials (NOT production) |
 | `DLC_DATABASE_PASSWORD` | `postgres` | |
 | `DLC_DATABASE_NAME` | `dance_lessons_coach_bdd_test` | Dedicated test DB |
 | `DLC_DATABASE_SSL_MODE` | `disable` | Tests run without TLS |
 Local setup:
 ```bash
 docker compose up -d                                                # Postgres container
 docker exec dance-lessons-coach-postgres psql -U postgres \
  -c "CREATE DATABASE dance_lessons_coach_bdd_test;"               # one-time
 ```
 In CI: `.gitea/workflows/ci-cd.yaml` provisions a Postgres service container and exports the same vars.
 ## Optional env vars
 ### `BDD_SCHEMA_ISOLATION` (since [PR #35](https://gitea.arcodange.lab/arcodange/dance-lessons-coach/pulls/35) — T12 stage 2/2)
 | Value | Behaviour |
 |---|---|
 | `true` | Each test PACKAGE (process) gets its own isolated PostgreSQL schema with migrations. Packages run in **parallel** safely. **~2.85x speedup observed locally.** This is the new default in CI. |
 | (unset / `false`) | Falls back to single shared `public` schema with `CleanupDatabase` (TRUNCATE) between scenarios. Forces sequential package execution (`-p 1`). Slower but simpler. |
 Implementation: `pkg/bdd/testserver/server.go Start()` builds a per-package isolated repo via `user.NewPostgresRepositoryFromDSN` (PR #34). `Stop()` drops the schema + closes the per-package pool.
 ADR-0025 documents the isolation strategy ("Implemented" since PR #35).
 ### `FEATURE` (per-package selector)
 When set, `pkg/bdd/testserver/server.go shouldEnableV2()` reads it. Used to scope per-feature behaviour (e.g. enable v2 endpoints only when `FEATURE=greet` AND `GODOG_TAGS` includes `@v2`).
 Without `FEATURE` set, falls back to `bdd` (generic).
 ### `GODOG_TAGS` (scenario filter)
 Standard godog env var. The default suite excludes flaky/todo/skip/v2 tags:
 ```
 GODOG_TAGS="~@flaky && ~@todo && ~@skip && ~@v2"
 ```
 Scoped runs (e.g. `@critical` only): set `GODOG_TAGS="@critical"` and run.
 ### `BDD_ENABLE_CLEANUP_LOGS` (debug)
 Set `=true` to log each scenario's CLEANUP / ISOLATION operation. Useful when debugging flakiness.
 ## Recommended local commands
 Run all BDD with isolation (parallel, fast):
 ```bash
 DLC_DATABASE_HOST=localhost DLC_DATABASE_PORT=5432 \
 DLC_DATABASE_USER=postgres DLC_DATABASE_PASSWORD=postgres \
 DLC_DATABASE_NAME=dance_lessons_coach_bdd_test DLC_DATABASE_SSL_MODE=disable \
 BDD_SCHEMA_ISOLATION=true \
 go test ./features/...
 ```
 Run one feature with v2 enabled:
 ```bash
 DLC_DATABASE_HOST=... \
 BDD_SCHEMA_ISOLATION=true FEATURE=greet GODOG_TAGS="@v2" \
 go test ./features/greet/...
 ```
 Repro CI conditions (sequential, no isolation):
 ```bash
 DLC_DATABASE_HOST=... \
 go test ./features/... -p 1
 ```

 # features/info/info.feature
@info @critical
 Feature: Info Endpoint
  The /api/info endpoint should return composite application information
  @basic @critical
  Scenario: GET /api/info returns all required fields
    Given the server is running
    When I request the info endpoint
    Then the status code should be 200
    And the response should be JSON
    And the response should contain "version"
    And the response should contain "commit_short"
    And the response should contain "build_date"
    And the response should contain "uptime_seconds"
    And the response should contain "cache_enabled"
    And the response should contain "healthz_status"
    And the "healthz_status" field should equal "healthy"
  @version @critical
  Scenario: version field matches semantic version pattern
    Given the server is running
    When I request the info endpoint
    Then the status code should be 200
    And the "version" field should match /^\d+\.\d+\.\d+$/
  @cache @skip @bdd-deferred
  Scenario: /api/info is cached when cache is enabled
    # Deferred: the BDD testsetup currently runs with cache disabled
    # (see "Cache service disabled" in test logs). Cache HIT/MISS behavior
    # is covered by unit tests on the cache service. Reopen this scenario
    # if/when the BDD harness gains a cache-enabled mode (likely after
    # ADR-0022 Phase 2).
    Given the server is running with cache enabled
    When I request the info endpoint
    Then the response header "X-Cache" should be "MISS"
    When I request the info endpoint again
    Then the response header "X-Cache" should be "HIT"
