Add convenience methods to simplify creating UI resources: - Content::ui_html(uri, html) - Create HTML UI resource (1 line vs 8) - Content::ui_resource(uri, mime_type, content) - Custom MIME types - Update ui-enabled-server example to use new helpers - Add comprehensive UI_RESOURCES_GUIDE.md documentation This reduces boilerplate by 87% for UI resource creation, making PulseEngine competitive with TypeScript SDK for ergonomics.
Remove non-library code from mcp-auth to focus on core functionality: - Delete CLI binaries (mcp-auth-cli, mcp-auth-setup, mcp-auth-init) - 3,759 lines - Delete performance.rs (benchmarking) - 840 lines - Delete setup/ directory (wizard) - 526 lines - Remove related dependencies (clap, dialoguer, colored, inotify) - Update lib.rs exports to remove deleted modules Total reduction: 5,125 lines (17% smaller) Final size: 25,112 lines → targeting 13K core in Phase 2 Addresses #64
…ead code ## Changes **Deleted Dead Code** (7,629 lines): - Removed `integration/` module (7,484 lines) - not exported in lib.rs, completely inaccessible to external crates - Updated lib.rs documentation to remove broken examples referencing integration module **Added Optional Features**: - `monitoring` - Security monitoring, event logging, and dashboards (2,154 lines) - `vault` - Enterprise vault integration for Infisical, etc. (1,412 lines: vault/ + manager_vault.rs) - `consent` - GDPR/CCPA compliance and consent management (1,167 lines) - Convenience features: `production` (monitoring + vault), `compliance` (consent + monitoring), `full` (all features) **Made reqwest Optional**: - `reqwest` now only required when `vault` feature is enabled ## Impact - **Lines removed**: 7,629 (30% reduction from Phase 1 result) - **Before Phase 2**: 25,109 lines - **After Phase 2**: 17,480 lines total - **Default build** (no features): ~13,758 lines (core library only) - **With all features**: 17,480 lines ## Testing - ✅ `cargo check --no-default-features` passes (core only) - ✅ `cargo check --features monitoring` passes - ✅ `cargo check --features vault` passes - ✅ `cargo check --features consent` passes - ✅ `cargo check --features full` passes (all features) ## Rationale - **integration/ module**: Dead code - existed in src/ but was never declared in lib.rs, making it completely inaccessible to external crates. Only used by internal tests. - **Optional features**: Allow users to opt-in to advanced functionality like security monitoring, vault backends, and compliance features without bloating the core library. - **Reduced core**: Default build is now ~13,758 lines of essential auth code, within target of ~13,000 lines. ## Related Issues Addresses #64 (Phase 2)

Key Discovery: Dead Code Removal
