Example Module Size Target +New minimal functional module should be ≤75 LOC (excluding tests). If exceeded, add a note: `// NOTE: size justification: <reason>`. + +Service registry benchmark harness lives in `service_registry_benchmark_test.go` and is the canonical reference for scale testing registration & lookup performance. Extend (not replace) when new patterns emerge. + +### Benchmark Governance +- When modifying core lookup/registration logic, run `go test -bench=Registry -benchmem` locally and include a summary in the PR description if deltas exceed ±10% on ns/op or allocs/op for any scale. +- If intentional performance regressions are introduced (e.g., for correctness or features), justify explicitly and open a follow‑up issue to explore mitigation. + +## Lint Configuration Policy + +- A single authoritative config: `.golangci.yml` at the repo root. Removed duplicate `.golangci.github.yml` to avoid drift. +- Add new linters only after: (1) zero false positives on current code, (2) documented rationale in this file, (3) PR includes fixes + enforcement. +- If a linter becomes noisy or blocks progress with low value, open a governance issue citing examples before disabling. +--- +Maintainers revisit this guide quarterly; propose updates via PR referencing constitution article alignment. + +## 18. DDD Boundaries & Glossary +- Each module defines its bounded context; expose only stable service interfaces—keep aggregates/entities internal. +- Maintain a glossary (central or module README) to align ubiquitous language across config fields, logs, and exported symbols. +- Anti-corruption layer wraps external clients; never leak third-party DTOs beyond infrastructure boundary—translate to domain structs. +- Domain services stay pure (no logging/IO); adapters handle side effects. + +## 19.

Identify Dynamic Fields + +Only mark fields as dynamic if they can be safely changed at runtime: + +✅ **Good Candidates:** +- Connection pool sizes +- Timeouts and intervals +- Log levels +- Feature flags +- Rate limits + +❌ **Not Suitable:** +- Database connection strings +- Server ports +- TLS certificates (use separate cert reload) +- Fundamental architecture settings + +### 2. Implement Atomic Updates + +Ensure configuration updates are atomic: + +```go +func (m *Module) Reload(ctx context.Context, changes []modular.ConfigChange) error { + // Create new configuration + newConfig := m.config.Clone() + + // Apply all changes + for _, change := range changes { + if err := applyChange(newConfig, change); err != nil { + return err // Rollback on any error + } + } + + // Validate new configuration + if err := newConfig.Validate(); err != nil { + return err + } + + // Atomic swap + m.mu.Lock() + m.config = newConfig + m.mu.Unlock() + + return nil +} +``` + +### 3.

Monitor Reload Health + +Use the circuit breaker to prevent reload storms: + +```go +// The system automatically backs off after failures +// Monitor these metrics: +- reload_attempts_total +- reload_failures_total +- reload_backoff_seconds +- reload_duration_seconds +``` + +## Troubleshooting + +### Common Issues + +#### 1. Reload Not Detecting Changes + +**Symptom:** Configuration file changes aren't being picked up + +**Solutions:** +- Verify file watcher is enabled in configuration +- Check file permissions +- Ensure `dynamic:"true"` tags are present +- Verify module implements `Reloadable` interface + +#### 2. Reload Failing with Timeout + +**Symptom:** Reload operations timing out + +**Solutions:** +- Increase `ReloadTimeout` in configuration +- Check module's `ReloadTimeout()` method +- Verify modules aren't blocking in `Reload()` +- Check for deadlocks in configuration updates + +#### 3.

Keep Health Checks Fast + +Health checks should complete quickly to avoid timeouts: + +```go +func (m *Module) HealthCheck(ctx context.Context) ([]modular.HealthReport, error) { + // Use context with timeout + checkCtx, cancel := context.WithTimeout(ctx, 100*time.Millisecond) + defer cancel() + + // Perform quick check + if err := m.quickPing(checkCtx); err != nil { + return []modular.HealthReport{{ + Module: m.Name(), + Status: modular.HealthStatusUnhealthy, + Message: "Quick check failed", + }}, nil + } + + // Don't do expensive operations in health checks + // ❌ Avoid: Full table scans, complex queries, large data transfers + // ✅ Prefer: Simple pings, connection checks, quick stats queries + + return []modular.HealthReport{{ + Module: m.Name(), + Status: modular.HealthStatusHealthy, + Message: "Operating normally", + }}, nil +} +``` + +### 2. Use Optional for Non-Critical Components + +Mark components as optional if they don't affect core functionality: + +```go +// Register optional components that won't affect readiness +app.RegisterHealthProvider("metrics", metricsProvider, true) // Optional +app.RegisterHealthProvider("cache", cacheProvider, true) // Optional +app.RegisterHealthProvider("database", dbProvider, false) // Required +``` + +### 3. Include Meaningful Details + +Provide useful debugging information in health reports: + +```go +return []modular.HealthReport{{ + Module: "api", + Component: "rate_limiter", + Status: modular.HealthStatusDegraded, + Message: "Rate limit approaching threshold", + CheckedAt: time.Now(), + Details: map[string]any{ + "current_rate": 850, + "limit": 1000, + "utilization_pct": 85, + "window": "1m", + "reset_at": time.Now().Add(15 * time.Second), + }, +}} +``` + +### 4. Handle Timeouts Gracefully + +Always respect context cancellation: + +```go +func (m *Module) HealthCheck(ctx context.Context) ([]modular.HealthReport, error) { + resultCh := make(chan []modular.HealthReport, 1) + errCh := make(chan error, 1) + + go func() { + reports, err := m.performHealthCheck() + if err != nil { + errCh <- err + } else { + resultCh <- reports + } + }() + + select { + case <-ctx.Done(): + return []modular.HealthReport{{ + Module: m.Name(), + Status: modular.HealthStatusUnknown, + Message: "Health check timed out", + }}, nil + case err := <-errCh: + return nil, err + case reports := <-resultCh: + return reports, nil + } +} +``` + +### 5. Cache Expensive Checks + +For expensive health checks, implement caching: + +```go +type CachedHealthProvider struct { + mu sync.RWMutex + lastCheck time.Time + lastReports []modular.HealthReport + cacheTTL time.Duration + actualCheck func(context.Context) ([]modular.HealthReport, error) +} + +func (p *CachedHealthProvider) HealthCheck(ctx context.Context) ([]modular.HealthReport, error) { + p.mu.RLock() + if time.Since(p.lastCheck) < p.cacheTTL { + reports := p.lastReports + p.mu.RUnlock() + return reports, nil + } + p.mu.RUnlock() + + // Perform actual check + reports, err := p.actualCheck(ctx) + if err != nil { + return nil, err + } + + // Update cache + p.mu.Lock() + p.lastReports = reports + p.lastCheck = time.Now() + p.mu.Unlock() + + return reports, nil +} +``` + +## Kubernetes Integration + +### Deployment Configuration + +```yaml +apiVersion: apps/v1 +kind: Deployment +metadata: + name: modular-app +spec: + template: + spec: + containers: + - name: app + image: myapp:latest + + # Liveness probe - restart if unhealthy + livenessProbe: + httpGet: + path: /health + port: 8080 + initialDelaySeconds: 30 + periodSeconds: 10 + timeoutSeconds: 5 + failureThreshold: 3 + + # Readiness probe - stop routing traffic if not ready + readinessProbe: + httpGet: + path: /ready + port: 8080 + initialDelaySeconds: 10 + periodSeconds: 5 + timeoutSeconds: 3 + failureThreshold: 2 +``` + +### Startup Probe (Kubernetes 1.16+) + +For slow-starting applications: + +```yaml +startupProbe: + httpGet: + path: /ready + port: 8080 + initialDelaySeconds: 0 + periodSeconds: 10 + timeoutSeconds: 5 + failureThreshold: 30 # 5 minutes to start +``` + +## Monitoring and Alerting + +### Prometheus Metrics + +The health system exposes Prometheus metrics: + +```prometheus +# Health check duration +health_check_duration_seconds{module="database",component="connection"} 0.002 + +# Health status (0=unknown, 1=healthy, 2=degraded, 3=unhealthy) +health_status{module="database",component="connection"} 1 + +# Aggregated health +health_aggregated_status{type="readiness"} 1 +health_aggregated_status{type="liveness"} 2 +``` + +### Example Alerts + +```yaml +groups: +- name: health + rules: + - alert: ServiceUnhealthy + expr: health_aggregated_status{type="readiness"} > 1 + for: 5m + annotations: + summary: "Service {{ $labels.service }} is unhealthy" + + - alert: ComponentDegraded + expr: health_status == 2 + for: 15m + annotations: + summary: "Component {{ $labels.module }}/{{ $labels.component }} degraded" +``` + +## Troubleshooting + +### Common Issues + +#### Health Checks Timing Out + +**Symptoms:** +- Health endpoints return 503 +- Logs show timeout errors + +**Solutions:** +1.

+This example demonstrates how to use the cache module for both in-memory and Redis caching with TTL support and cache operations. + +## Overview + +The example sets up: +- In-memory cache with configurable TTL +- Redis cache configuration (when available) +- Cache operations: Set, Get, Delete, Clear +- HTTP API endpoints to interact with the cache +- Automatic expiration handling + +## Features Demonstrated + +1. **Multi-Backend Caching**: Both in-memory and Redis support +2. **TTL Support**: Time-to-live for cache entries +3. **Cache Operations**: Basic CRUD operations on cache +4. **HTTP Integration**: RESTful API for cache management +5. **Configuration**: Configurable cache backends and settings + +## API Endpoints + +- `POST /api/cache/:key` - Set a value in cache with optional TTL +- `GET /api/cache/:key` - Get a value from cache +- `DELETE /api/cache/:key` - Delete a value from cache +- `DELETE /api/cache` - Clear all cache entries +- `GET /api/cache/stats` - Get cache statistics + +## Running the Example + +1. Start the application: + ```bash + go run main.go + ``` + +2. The application will start on port 8080 + +## Testing Cache Operations + +### Set a value in cache +```bash +curl -X POST http://localhost:8080/api/cache/mykey \ + -H "Content-Type: application/json" \ + -d '{"value": "Hello, World!", "ttl": 3600}' +``` + +### Get a value from cache +```bash +curl http://localhost:8080/api/cache/mykey +``` + +### Set with different TTL +```bash +curl -X POST http://localhost:8080/api/cache/shortlived \ + -H "Content-Type: application/json" \ + -d '{"value": "This expires in 10 seconds", "ttl": 10}' +``` + +### Delete a specific key +```bash +curl -X DELETE http://localhost:8080/api/cache/mykey +``` + +### Clear all cache entries +```bash +curl -X DELETE http://localhost:8080/api/cache +``` + +### Get cache statistics +```bash +curl http://localhost:8080/api/cache/stats +``` + +## Configuration + +The cache module is configured in `config.yaml`: + +```yaml +cache: + backend: "memory" # or "redis" + default_ttl: 3600 # 1 hour in seconds + memory: + cleanup_interval: 600 # cleanup every 10 minutes + redis: + address: "localhost:6379" + password: "" + db: 0 + max_retries: 3 + pool_size: 10 +``` + +## Cache Backends + +### In-Memory Cache +- Fast access for single-instance applications +- Automatic cleanup of expired entries +- Configurable cleanup intervals +- Memory-efficient with TTL support + +### Redis Cache +- Distributed caching for multi-instance applications +- Persistent storage with Redis features +- Connection pooling and retry logic +- Production-ready scalability + +## Error Handling + +The example includes proper error handling for: +- Cache backend connection failures +- Key not found scenarios +- Invalid TTL values +- Serialization/deserialization errors +- Network issues with Redis + +This demonstrates how to integrate caching capabilities into modular applications for improved performance. \ No newline at end of file diff --git a/examples/cache-demo/config.yaml

+1. **Type Validation**: Ensuring correct data types (string, number, boolean, etc.) +2. **Required Fields**: Validating that required fields are present +3. **Format Validation**: Email, date-time, and custom format validation +4. **Range Constraints**: Minimum/maximum values for numbers +5. **String Constraints**: Length restrictions and pattern matching +6. **Array Validation**: Item validation and uniqueness constraints +7. **Enum Validation**: Restricting values to predefined sets +8. **Nested Object Validation**: Validating complex object structures +9. **Additional Properties**: Controlling whether extra fields are allowed + +## Error Handling + +The API returns detailed validation errors: + +```json +{ + "valid": false, + "errors": [ + "missing property 'email'", + "property 'age': must be <= 150", + "property 'role': value must be one of [admin, user, guest]" + ] +} +``` + +## Schema Standards + +All schemas follow JSON Schema Draft 2020-12 specification: +- `$schema` declaration for version compatibility +- Proper type definitions and constraints +- Clear validation rules and error messages +- Support for nested objects and arrays +- Format validation for common data types + +## Configuration + +No special configuration is required for the JSON Schema module. It works with the default Modular framework configuration. + +## Architecture + +``` +┌─────────────────┐ ┌─────────────────┐ ┌─────────────────┐ +│ HTTP Client │────│ REST API │────│ Schema Service │

Staging Environment Safety +- Uses Let's Encrypt staging environment to avoid rate limits +- Generates untrusted certificates for testing purposes +- Safe for development and demonstration + +### 2. Certificate Information +View detailed certificate information including: +- Subject and issuer details +- Validity period (not before/after dates) +- Supported domain names (SAN) +- Serial number and CA status + +### 3. TLS Connection Analysis +Inspect TLS connection properties: +- TLS version (1.2, 1.3) +- Cipher suite negotiated +- Protocol negotiation results +- Handshake completion status + +### 4. Security Headers +Demonstrates security best practices: +- `Strict-Transport-Security` (HSTS) +- `X-Content-Type-Options` +- `X-Frame-Options` +- `X-XSS-Protection` + +### 5. Interactive Web Interface +Browser-accessible interface showing: +- Current connection security status +- Certificate configuration details +- Links to API endpoints for testing +- Production setup guidance + +## Example Usage + +### Check SSL Status + +```bash +# Get comprehensive SSL information +curl -k https://localhost:8443/api/ssl/info | jq . + +# Run security tests +curl -k https://localhost:8443/api/ssl/test | jq . + +# Check certificate service +curl -k https://localhost:8443/api/ssl/certificates | jq . +``` + +### Browser Testing + +1. Open `https://localhost:8443/` in your browser +2. Accept the security warning (staging certificates are untrusted) +3. View the interactive interface showing SSL status +4. Click on API endpoints to test functionality + +### Certificate Inspection + +```bash +# View certificate details with OpenSSL +echo | openssl s_client -connect localhost:8443 -servername localhost 2>/dev/null | openssl x509 -text -noout + +# Check certificate expiry +echo | openssl s_client -connect localhost:8443 2>/dev/null | openssl x509 -noout -dates +``` + +## Production Setup + +To use this for production with real certificates: + +### 1.

DNS Configuration + +- Point your domain's A/AAAA records to your server's IP +- Ensure DNS propagation is complete before starting + +### 3. Firewall Configuration + +```bash +# Allow HTTP (for ACME challenges) +sudo ufw allow 80/tcp + +# Allow HTTPS +sudo ufw allow 443/tcp +``` + +### 4. Domain Validation + +- Ensure your server is reachable on port 80 for HTTP-01 challenges +- Or configure DNS-01 challenges for wildcard certificates + +## Certificate Management + +### Automatic Renewal +- Certificates are automatically renewed 30 days before expiry +- No manual intervention required +- Renewal process is logged for monitoring + +### Manual Operations +```bash +# Force certificate renewal (if needed) +# This would be done through the application's management interface +``` + +### Storage +- Certificates are stored in the configured `storage_path` +- Account information is persisted for renewals +- Secure file permissions are automatically set + +## Security Considerations + +### Development/Testing +- ✅ Use staging environment (`use_staging: true`) +- ✅ Use localhost/test domains +- ✅ Accept certificate warnings in browsers + +### Production +- ✅ Use production environment (`use_staging: false`) +- ✅ Use real, publicly accessible domains +- ✅ Implement proper monitoring for certificate expiry +- ✅ Backup certificate storage directory +- ✅ Use secure file permissions for certificate storage + +## Troubleshooting + +### Common Issues + +1. **Rate Limits**: Use staging environment for testing +2. **Domain Validation**: Ensure domains point to your server +3. **Firewall**: Check ports 80 and 443 are accessible +4. **DNS**: Wait for DNS propagation after domain changes + +### Debug Mode + +Enable detailed logging: +```go +logger := slog.New(slog.NewTextHandler(os.Stdout, &slog.HandlerOptions{ + Level: slog.LevelDebug, +})) +``` + +### Certificate Verification + +```bash +# Check if certificate is valid +curl -I https://yourdomain.com + +# Test with multiple tools +openssl s_client -connect yourdomain.com:443 -servername yourdomain.com +``` + +## Architecture + +``` +┌─────────────────┐ ┌─────────────────┐ ┌─────────────────┐ +│ HTTPS Client │────│ TLS Server │────│ Let's Encrypt │ +└─────────────────┘

Demo Configuration

+

This demo is configured to use Let's Encrypt's staging environment for safety.

+

Staging certificates are not trusted by browsers but demonstrate the ACME protocol flow.

+
+ +

🧪 Test Endpoints

+ + +

🔧 Configuration Notes

+
+

Domains: localhost, 127.0.0.1 (for demo purposes)

+

Environment: Let's Encrypt Staging

+

Auto-Renewal: Enabled (30 days before expiry)

+

Storage: ./certs directory

+
+ +

⚠️ Production Setup

+
+

For production use:

+
    +
  • Set use_staging: false in configuration
    • +
  • Use real domain names (not localhost)
    • +
  • Ensure domain DNS points to your server
    • +
  • Open port 80 for HTTP-01 challenges (or configure DNS-01)
    • +
  • Set proper email for Let's Encrypt notifications
    • +

Each module: +- Clearly states purpose and dependencies +- Implements required framework interfaces directly (no adapter boilerplate unless justified) +- Is independently testable and documented + +### II. Deterministic Lifecycle & Dependency Transparency +Module registration, dependency resolution, and start/stop ordering MUST be deterministic and inspectable. Circular dependencies are rejected with explicit cycle reporting. Shutdown strictly reverses successful start order. + +### III. Configuration Integrity & Provenance +All configuration derives from declared feeders (environment, file, programmatic). Every field has: source (provenance), default (optional), required flag, description, and optional dynamic flag. Missing required values or invalid data abort startup. + +### IV. Multi-Tenant & Instance Isolation +Tenant and instance contexts provide hard isolation boundaries. Cross-tenant leakage (data, cache, services) is prohibited. Tenant-specific services require explicit tenant context. + +### V. Observability & Accountability +Lifecycle events, health states, configuration provenance, and error taxonomy (Config, Validation, Dependency, Lifecycle, Security) MUST be emitted or derivable. Metrics cardinality guardrails warn on potential explosion (>100 tag values / 10m per dimension). + +### VI. Test-First (NON-NEGOTIABLE) +No production code without a failing test first. Red → Green → Refactor loop is mandatory. Every new feature/update includes: +- Gherkin/BDD scenario(s) mapping to acceptance criteria +- Integration tests exercising real module interactions (not mocks for core behavior) +- Unit tests only for pure logic or boundary transformations + +### VII. Realistic Testing & Fidelity +Tests MUST execute actual framework code paths and real integrations where defined (e.g., real Postgres or ephemeral in-memory substitute only when semantically equivalent). Forbidden: +- Mocking core lifecycle or service registry +- Tests asserting only that mocks are called without validating observable outcomes +- Synthetic scenarios that omit error handling or boundary conditions present in spec + +### VIII. Extensibility with Restraint +Extension points (decorators, observers, feeders, modules) are provided where concrete needs exist. Speculative abstraction is deferred until at least two distinct use cases demand it. + +### IX. Semantic Versioning & Predictable Evolution +Core and modules follow SemVer. Breaking changes require a deprecation path ≥1 minor version and documented migration notes. + +### X. Performance & Operational Baselines +- Bootstrap (<200ms for 10 modules typical target) +- Config load (<2s for 1000 fields) +- O(1) expected service lookup +- Bounded scheduler catch-up (default skip, optional limited backfill) + +### XI. Idiomatic Go & Boilerplate Minimization +Modules and core packages MUST embrace idiomatic Go: +- Prefer composition over inheritance-like indirection; keep exported surface minimal. +- Avoid unnecessary interface abstraction; define an interface in the consumer package only when ≥2 implementations or a mock need exists. +- Zero-cost defaults: constructing a config or module with zero values should be valid unless explicitly unsafe. +- No reflection in hot paths unless justified with benchmark + comment. +- Cap constructor parameter count via option structs/functional options (>5 primitive params requires refactor). +- Generics: only when they measurably reduce duplication without harming clarity (add benchmark or LOC delta reference in PR description). +- Eliminate duplicate helper utilities by centralizing into internal packages when shared ≥2 call sites. + +### XII. Public API Stability & Review +Any exported (non-internal) symbol constitutes public API. Changes gated by: +- API diff tooling (see `API_CONTRACT_MANAGEMENT.md`) must show no unintended removals/semantic changes. +- Adding exported symbols requires rationale & usage example in docs or examples. +- Deprecations use `// Deprecated: . Removal in vX.Y (≥1 minor ahead).` comment form. +- Removal only after at least one released minor version containing deprecation notice. + - Additive changes that alter constructor or interface method signatures (even if they compile for existing callers using type inference) are treated as potential breaking changes and MUST first be evaluated for delivery via the Builder pattern (additional fluent option) or Observer pattern (decoupled event/listener) to minimize disruption. + - Prefer evolving configuration and extensibility surfaces through: (1) new Builder option methods with sensible defaults, (2) optional functional options, or (3) observer hooks, before mutating existing interfaces. + - Interface widening (adding a method) is forbidden without a deprecation + adapter path; instead, introduce a new narrow interface and have existing types opt-in, or expose capability via an observer or builder-provided service. + +### XIII. Documentation & Example Freshness +Documentation is a living contract: +- Every new feature/update: docs + examples updated in same PR; failing to do so blocks merge. +- Root `DOCUMENTATION.md` + module READMEs MUST not reference removed symbols (enforced by periodic doc lint task—future automation placeholder). +- Examples must compile & pass tests; stale examples are treated as defects. +- Config field additions require: description tag, default (if optional), and provenance visibility. +- A “Why it exists” paragraph accompanies any new module or extension point. + +### XIV. Boilerplate Reduction Targets +We continually measure and reduce ceremony: +- New minimal module (config + one service) target: ≤75 lines including tests scaffold (excluding generated mocks). +- If repeated snippet appears ≥3 times (excluding tests), refactor or justify in PR. +- Provide code generators (CLI) only after manual pattern stabilizes across ≥2 modules. + +### XV. Consistency & Style Enforcement +- `golangci-lint` must pass (or documented waivers with justification + issue link). +- Uniform logging fields: `module`, `tenant`, `instance`, `phase` where applicable. +- Error messages start lowercase, no trailing punctuation, and include context noun first (e.g., `config: missing database host`). +- Panics restricted to programmer errors (never for invalid user config) and documented. +- All concurrency primitives (mutexes, channels) require a brief comment describing ownership & lifecycle. + +### XVI. Strategic Patterns (Builder, Observer, Domain-Driven Design) +The project intentionally standardizes on these patterns to enable low-friction evolution and clear domain boundaries: + +1. Builder Pattern + - All complex module/application construction SHOULD expose a builder (or functional options) to allow additive evolution without breaking existing callers. + - New optional capabilities MUST prefer builder option methods (or functional options) over adding required constructor parameters. + - Required additions should be extremely rare; if needed, provide a transitional builder option that derives a sensible default while emitting a deprecation notice for future mandatory requirement. + - Builder options MUST be side-effect free until `.Build()` / finalization is invoked. + +2. Observer Pattern + - Cross-cutting concerns (metrics emission, auditing, tracing, lifecycle notifications) MUST prefer observers instead of embedding new dependencies into existing module interfaces. + - New event types require: clear naming (`lifecycle.*`, `config.*`, `tenant.*`), documented payload contract, and tests asserting emission timing & ordering. + - Avoid tight coupling: observers should depend only on stable event contracts, not concrete module internals. + +3. Domain-Driven Design (DDD) + - Modules map to bounded contexts; a module's exported services form its public domain API. + - Ubiquitous language: configuration field names, log keys, and service method names reflect domain terms consistently. + - Aggregates enforce invariants internally; external packages manipulate them only through exported behaviors (not by mutating internal state structs). + - Anti-corruption layers wrap external systems; never leak external DTOs beyond the boundary—translate to domain types. + - Domain logic remains decoupled from transport (HTTP, CLI, messaging). Adapters live in dedicated subpackages or modules. + +4. API Evolution via Patterns + - Before modifying an existing interface or constructor, authors MUST document (in PR description) why a Builder or Observer extension is insufficient. + - Event-based (Observer) extension is preferred for purely informational additions; Builder extension is preferred for configuration or capability toggles. + - When neither pattern suffices and an interface change is unavoidable, provide: (a) deprecation of old interface, (b) adapter implementation bridging old to new, (c) migration notes, (d) versioned removal plan per Article XII. + +Compliance with this article is part of API review; reviewers should request justification when direct interface mutation occurs. + +--- + +## Additional Constraints & Standards +- Dynamic configuration limited to fields explicitly tagged `dynamic`; hot reload performs full validation before applying. +- Secrets must never be logged in plaintext; provenance redacts values. +- Scheduling backlog policies are configurable and bounded. +- Certificate renewal begins 30 days pre-expiry; escalation if <7 days remaining without success. +- Health model: healthy|degraded|unhealthy; aggregate readiness excludes optional module failures. + +--- + +## Development Workflow & Quality Gates + +### Workflow Phases +1. Specification (spec.md) → clarifications resolved. +2. Planning (plan.md) → research, data model, contracts, quickstart. +3. Task Generation (tasks.md) → ordered test-first tasks. +4. Implementation → execute tasks in TDD order. +5. Validation → run full lint + tests + performance smoke. + +### Mandatory Artifacts per Feature +- spec.md with acceptance scenarios +- plan.md with research & contracts references +- research.md (decisions + rationale) +- data-model.md, contracts/*, quickstart.md +- BDD tests covering each acceptance scenario +- tasks.md (pre-implementation) + +### Testing Requirements +- Each acceptance scenario → at least one Gherkin scenario (.feature) or structured BDD equivalent. +- Integration tests MUST verify real side-effects (e.g., service registry resolution, lifecycle ordering, config validation failures). +- Edge cases (error paths, invalid config, multi-tenant isolation) MUST have explicit test coverage. +- Prohibited: tests that only assert method call order on mocks; replace with observable state or output assertions. + +### Gate Checks (PR MUST show): +- All new/changed required fields documented with description & default (if any) +- No unresolved TODO placeholders in production code +- Lint passes or justified exceptions documented in PR description +- All tests pass across: core, each module, examples, CLI +- Added capability mapped to at least one failing test prior to implementation (reviewers verify commit history ordering where feasible) + +### Performance & Observability Checks +- Startup path measured when adding new module categories (baseline vs previous run) +- Cardinality warnings investigated (either reduce dimensions or justify) +- Health and lifecycle event emission verified in integration tests for new modules. + +--- + +## BDD & Gherkin Policy +- Every feature's acceptance criteria must be mirrored in a Gherkin `.feature` file (or equivalent structured test) using Given/When/Then. +- Scenarios must avoid artificial stubs for core flows (e.g., do not stub module Start; invoke real start sequence). +- Scenario failure messages must guide debugging (include module name, phase, expectation). + +--- + +## Governance +- This Constitution supersedes ad-hoc practices. Deviations require an amendment PR updating this file with rationale and migration notes. +- Reviewers enforce: TDD compliance, realistic test fidelity, semantic versioning, deprecation process. +- Complexity must be justified in PR description if exceeding norms (e.g., adding new global coordination mechanism). +- Any new extension point demands: documented concrete use cases, tests, and quickstart update. +- Amendments require consensus (≥2 maintainers approval) and version increment of this document. + +--- + +## Amendment Log +- 1.2.0 (2025-09-07): Added Article XVI emphasizing Builder, Observer, and DDD patterns;

The developer supplies configuration via multiple sources, starts the application once, and expects deterministic ordering, automatic validation, observability hooks, and graceful startup/shutdown across all modules without needing to hand-craft dependency wiring. + +### Supporting Personas +- Application Developer: Assembles and runs the composed application. +- Module Author: Creates reusable modules that conform to framework interfaces and offer services. +- Operator / DevOps: Provides configuration (env, files), monitors lifecycle events, manages secrets and rotation. +- Tenant Administrator: Manages tenant-specific configuration and isolation boundaries. +- Security / Compliance Reviewer: Verifies auth, auditing, and isolation guarantees. + +### Acceptance Scenarios +1. **Given** a set of modules each declaring required services and configuration, **When** the application initializes, **Then** the framework MUST resolve dependencies (by name or interface), apply defaults, validate all configuration, and start modules in an order that satisfies dependencies. +2. **Given** a module fails during Start after some modules already started, **When** the failure occurs, **Then** the framework MUST emit lifecycle events, stop all previously started startable modules in reverse order, and return a wrapped error describing the failure cause. +3. **Given** multiple configuration feeders (environment variables, file-based, programmatic), **When** the application loads configuration, **Then** the system MUST merge them respecting precedence rules and track which feeder provided each field for auditing. +4. **Given** a multi-tenant application with tenant-specific configs, **When** per-tenant services are requested, **Then** the framework MUST provide isolated instances without cross-tenant leakage. +5. **Given** a module exposes services through the service registry, **When** another module requests those services by interface or explicit name, **Then** the lookup MUST succeed if a compatible provider exists or produce a descriptive error if not. +6. **Given** observers are registered, **When** lifecycle or configuration events occur, **Then** observers MUST receive structured event data in deterministic sequence without blocking the core lifecycle (or with defined handling of slow observers). +7. **Given** the CLI tool is used to generate a new module skeleton, **When** the developer runs the generation command, **Then** the scaffold MUST include required interface implementations and documentation placeholders. +8. **Given** a graceful shutdown is triggered, **When** the application stops, **Then** all stoppable modules MUST receive stop signals in reverse start order, ensuring resource cleanup. +9. **Given** configuration contains invalid values (missing required, type mismatch, failed custom validation), **When** validation runs, **Then** startup MUST abort with aggregated, actionable error messages referencing fields and sources. +10. **Given** circular dependencies between modules exist, **When** the application is built or started, **Then** the system MUST detect and report the cycle without deadlock. + +### Edge Cases +- Circular dependency chain across >2 modules. +- Missing required configuration field after applying all defaults and feeders. +- Multiple providers for the same interface where selection rules are ambiguous. +- Module requests a service that becomes available only after its own Start (ordering mis-declaration). +- Failure during partial multi-tenant initialization leaves some tenants initialized and others not. +- Rapid successive tenant configuration updates while services are in use. +- Slow or failing observer causing potential lifecycle delays (handling/backpressure requirement). +- Configuration feeder unavailable (e.g., file missing, env not set) yet marked required. +- Reverse proxy / HTTP server module bound port already in use at startup. +- Scheduler job execution overlapping previous long-running instance. +- Certificate (Let's Encrypt) renewal failure near expiry. +- Auth module key rotation occurring during active token validation. +- Event bus subscriber panic or processing timeout. +- Cache backend network partition. +- Database connection pool exhaustion under burst load. + +### Clarified Constraints & Previously Open Items +- Performance Targets: Framework bootstrap (10 modules) SHOULD complete < 200ms on baseline modern VM; configuration load for up to 1000 fields SHOULD complete < 2s; average service lookup MUST be O(1) expected time. These act as guidance baselines, not hard SLAs. +- Data Retention: Configuration provenance tracking data SHOULD be retainable for 30 days (policy hook provided) with ability to plug extended archival. Sensitive secrets MUST NOT be stored in provenance values (only source reference, redacted value indicator). +- Compliance Alignment: Logging & auditing facilities MUST enable generation of evidence for SOC2 style controls (startup/shutdown events, configuration validation results, error classifications). No specific HIPAA/PII handling mandated in baseline. +- Observability Cardinality: Metrics/tracing tags SHOULD avoid unbounded cardinality; default guardrails MUST warn when >100 distinct values for a single tag within a rolling 10m window. +- Tenant Scaling: Baseline target support is 100 concurrently active tenants per process; framework MUST remain functionally correct up to 500 tenants (performance may degrade); beyond 500 is a scaling strategy consideration (sharding / multi-process). +- Archival & Deletion: Framework provides hooks; enforcement of domain-specific retention/deletion logic is responsibility of application modules. +- Security Keys & Secrets: Secrets MUST be injectable through feeders and MUST never be logged in plaintext (redaction required). +- Backward Compatibility: Minor version updates MUST maintain stable public module interfaces; breaking changes only in a major version with deprecation notice of ≥1 minor release. + +## Requirements

allow modules to declare optional dependencies that do not block startup if absent. +- **FR-034**: System MUST provide enhanced diagnostics for interface-based dependency resolution mismatches. +- **FR-035**: System MUST maintain accurate state transitions preventing double-start or double-stop of a module. +- **FR-036**: System MUST prevent partial registration (all-or-nothing) when encountering invalid module declarations. +- **FR-037**: System MUST permit dynamic inspection/debugging of registered module interfaces at runtime. +- **FR-038**: System MUST secure multi-tenant boundaries via: separate per-tenant config namespaces, mandatory tenant context for tenant-scoped service retrieval, and runtime guards preventing registration of tenant-scoped services without explicit tenant identifier. +- **FR-039**: System MUST ensure scheduled jobs missed during downtime are handled by a configurable catch-up policy (default: do not backfill; optional: backfill up to last 10 missed executions or 1 hour of backlog, whichever smaller). +- **FR-040**: System MUST document and expose configuration descriptions for each field (human-readable metadata). +- **FR-041**: System MUST allow layering of configurations (base + instance + tenant) with predictable override rules. +- **FR-042**: System MUST support emitting structured events externally (e.g., cloud events) without impacting core timing. +- **FR-043**: System MUST ensure failure in observer processing does not crash the core lifecycle unless explicitly configured. +- **FR-044**: System MUST provide clear errors when multiple candidate services satisfy an interface; tie-break order: explicit name match > provider priority metadata > earliest registration time; if still ambiguous fail with enumerated candidates. +- **FR-045**: System MUST support hot-reload of configuration fields explicitly tagged as dynamic, re-validating and invoking a Reloadable interface on affected modules; non-dynamic fields require restart. +- **FR-046**: System MUST offer a consistent error classification scheme comprising: ConfigError, ValidationError, DependencyError, LifecycleError, SecurityError (extensible for domain categories). +- **FR-047**: System MUST provide structured logging correlation with lifecycle events. +- **FR-048**: System MUST allow modules to expose health/readiness signals (status: healthy|degraded|unhealthy, message, timestamp); aggregate readiness MUST exclude optional module failures; aggregate health reflects worst status. +- **FR-049**: System MUST ensure secrets (auth keys, DB creds) can be supplied via feeders without accidental logging. +- **FR-050**: System MUST provide guidance for versioning: core and modules follow SemVer; minor versions retain backward compatibility; modules declare minimum core version; deprecations announced one minor version before removal. + +### Non-Functional Highlights (Derived & Finalized) +- Reliability: Graceful shutdown & reverse start ordering required; failed start triggers coordinated rollback. +- Observability: Provenance tracking, lifecycle events, health aggregation, ambiguity diagnostics; guardrails on metric cardinality. +- Extensibility: Modules, decorators, feeders, observers, and error taxonomy are open extension points. +- Security: Tenant isolation, secret redaction, pluggable auth, controlled dynamic config. +- Performance: Bootstrap (<200ms for 10 modules), config load (<2s for 1000 fields), O(1) average service lookup guideline. +- Scalability: 100 active tenants baseline (functional to 500) + horizontal scaling pattern; 500 services per process guideline. +- Maintainability: Semantic versioning policy; deprecation cycle = 1 minor release. +- Operability: Health/readiness model and structured events enable automation tooling. + +### Measurable Success Criteria (Guidance / Regression Guards) +| Area | Metric | Target P50 | Target P95 | +|------|--------|-----------:|-----------:| +| Bootstrap (baseline app) | Time to Ready | <150ms | <300ms | +| Configuration Load | Load & validate duration | <1.0s | <2.0s | +| Service Lookup | Average lookup latency | <2µs | <10µs | +| Tenant

secret model docs merged. + +### Key Entities *(include if feature involves data)* +- **Application**: Top-level orchestrator managing module lifecycle, dependency resolution, configuration aggregation, and tenant contexts. +- **Module**: Pluggable unit declaring configuration, dependencies, optional start/stop behaviors, and provided services. +- **Service Registry Entry**: Mapping of

Structured notification representing state transition (registering, starting, started, stopping, stopped, error). +- **Tenant Context**: Isolation token carrying tenant identity and associated configuration for service scoping. +- **Instance Context**: Identifier enabling multiple logical instances within a single process runtime. +- **Scheduled Job Definition**: Declarative schedule plus execution contract tracked by scheduler module. +- **Event Message**: Asynchronous payload transported via event bus with topic/routing metadata. +- **Certificate Asset**: Managed TLS material bound

Typical buckets: +- Domain entities/value objects & invariants. +- Application use cases (orchestrating domain + ports). +- Interface adapters (HTTP handlers, CLI commands) – thin. +- Repository interfaces already defined; implementations deferred to Integration. +- Builder options implemented minimally (no side effects until final Build/Start). +- Observer event publishing code added only after emission tests exist. + +## Phase 3.4: Integration / Adapters +Add concrete infrastructure & cross-cutting concerns: +- Persistence adapters (DB, migrations) in `internal/infrastructure/persistence/`. +- External service clients, cache, messaging. +- Observability wiring (logging, tracing, metrics) in `internal/platform/`. +- Observer registration & lifecycle integration. +- Config loading & validation. + +## Phase 3.5: Hardening & Polish +- Additional edge-case & property tests. +- Performance / load validation (thresholds from plan). +- Security review (timeouts, input validation, error wrapping). +- Documentation updates & sample configs regeneration. +- Refactor duplication (rule of three) & finalize public API surface. +- Confirm no interface widening slipped in without adapter + deprecation. +- Validate event schema stability (no late changes without test updates). + +## Phase 3.6: Test Finalization (Placeholder / Skip Elimination) +Purpose: Ensure no latent placeholders remain and all originally deferred scenarios now assert real behavior. +- Scan all test files for markers: `TODO`, `FIXME`, `SKIP`, `t.Skip`, `t.Skipf`, `placeholder`, `future implementation`. +- Replace each with concrete test logic or remove if obsolete (document rationale in commit message if removed). +- Ensure every scenario previously outlined in spec/plan has an asserting test (no silent omission). +- Verify no test relies on sleep-based timing without justification (use deterministic synchronization where possible). +- Confirm code coverage for critical paths (domain invariants, error branches, boundary conditions) — add tests where gaps exist. + +## Dependencies (Template Rules) +- All contract & domain tests precede related implementation tasks. +- Domain layer precedes application (use case) layer; application precedes interface/delivery. +- Infrastructure adapters depend on repository interfaces & domain types. +-

when file paths & data dependencies are isolated. +- Ensure commit history shows RED → GREEN → REFACTOR pattern. +- Prefer early vertical slice to reduce integration risk. +- Avoid speculative abstractions; wait for repetition (≥3 occurrences). + +## Task Generation Rules +*Applied during main() execution* + +1. **From Contracts**: + - Each contract file → contract test task [P]. + - Each
