Subject: [PATCH 01/14] Update environment configuration and add example
 environment file

Refined `.gitignore` to include specific environment files, replacing the generic folder exclusion. Introduced `environments.example.ts` with placeholder values for API keys and configurations to provide a template for setup.

Subject: [PATCH 04/14] ### Commit Message

**Integrate Background Service and Chat Module with Firebase enhancements**

- Added `BackgroundExampleComponent`, `FullScreenBackgroundComponent`, and `BackgroundService` for advanced background management, including video, image, and parallax configurations.
- Introduced a new `ChatBotService` to manage chat functionalities, supporting messages, reactions, and real-time chat features.
- Updated environment configuration files (`environment.ts`, `environment.local.ts`, `environment.dev.ts`, `environment.prod.ts`) with Firebase database URL and API keys.
- Enhanced Firebase compatibility by upgrading dependencies (`firebase: ^11.8.1`).
- Refactored appearance settings in `AppearanceSettingsComponent`, removing unused methods (`getThemeClass()`), and added debug logs.
- Added new helper logic in `SettingsService` for improved form syncing, with comprehensive logging for debugging.
- Included placeholder-based example environment for easier setup (`environments.example.ts`).

Subject: [PATCH 05/14] ### Add FirestoreService and
 FullScreenBackgroundComponent for Firebase and UI enhancements

- Implemented `FirestoreService` to streamline Firestore operations, including document CRUD operations, real-time updates, and file management in Firebase Storage.
- Added `FullScreenBackgroundComponent` with support for video, image, gradient, and parallax background functionalities. Integrated video providers such as YouTube and Vimeo with customizable configurations.
- Included unit tests for `FirestoreService` and `FullScreenBackgroundComponent` to ensure reliability and maintainability.
- Enhanced modularity and reusability by following Angular's best practices and incorporating RxJS for handling asynchronous operations.

Subject: [PATCH 06/14] ### Remove unused Firebase polyfill script

- Deleted the `polyfills-FFHMD2TL.js` file from the Firebase hosting configuration as it is no longer required.
- Cleaned up unnecessary assets to streamline the hosting setup and reduce potential maintenance overhead.

Subject: [PATCH 07/14] ### Add automated Firebase deployment workflow and
 environment variable handling

- Created a GitHub Actions workflow (`firebase_deployment_workflow.yml`) to automatically deploy the application to Firebase Hosting on pushes to the `main` branch.
  - Includes steps for Node.js setup, dependency installation, build process, and deployment.
  - Added secure integration via GitHub Secrets for sensitive environment variables.
- Updated `environment.ts` to use environment variables for Firebase and third-party API configurations, removing hard-coded sensitive data.
- Refined `.gitignore` to exclude `.env` files and environment-specific configuration files for better security and maintainability.

Subject: [PATCH 08/14] ### Introduce separate environment configuration files
 for development and production

- Added `environment.dev.ts` and `environment.prod.ts` to segregate environment-specific configurations.
- Defined placeholders for `APP_TITLE`, `API_URL`, Firebase credentials, and API keys to enhance security and flexibility.
- Updated `.gitignore` to exclude environment configuration files (`environment.dev.ts` and `environment.prod.ts`) to avoid committing sensitive information.

This change improves maintainability, aligns with best practices, and supports better environment handling for deployments.

Subject: [PATCH 09/14] ### Replace environment variable bindings with
 placeholder values

- Updated `environment.ts`, `environment.dev.ts`, and `environment.prod.ts` to replace `process.env` bindings with placeholder values for configurations like `APP_TITLE`, `APP_API_URL`, Firebase credentials, and API keys.
- Removed reliance on dynamic environment variables for streamlined configuration setup and improved clarity in local, development, and production environments.
- Included comments to guide users in properly configuring environment values during setup.

This change enhances security by removing hardcoded fallback values and simplifies the onboarding process for developers.

 Main components

- Replaced hardcoded GitHub URL in `projects-overview.component.html` with dynamic binding using the `githubUrl` property for better reusability and maintainability.
- Updated the `githubUrl` value in `main.component.html` to point to the appropriate repository (`ColinMichaels-Angular`).

Subject: [PATCH 11/14] ### Enhance Unit Tests with Mocks and Dependency
 Injection Updates

- Added testing utilities to multiple component and service tests:
  - Integrated `provideHttpClient` and `provideHttpClientTesting` in `weather`, `dock`, and `finder-app` component tests to enable HTTP testing capabilities.
  - Added `RouterTestingModule` to `projects-overview.component.spec` for router-related tests.
  - Mocked dependencies with Jasmine spies in unit tests for `auth.service`, `home-terminal-window.component`, and `cli-game.component`.
- Refactored `auth.service` to gracefully handle the absence of Firebase services by making `Auth` injection optional and introducing fallback behaviors.
- Wrapped Firebase Firestore and Storage calls in helper methods within `firestore.service` to improve testability and maintain runtime behavior consistency.
- Enhanced `firestore.service` to handle optional Firestore injection and replaced direct Firestore method calls with wrapper functions, enabling streamlined mocking for tests.
- Made `realtime-db.service` initialization conditional to allow null-safe usage.

These changes improve test reliability, maintainability, and resilience, enabling easier mocking and dependency injection for unit testing.

+You are a senior Staff-level Angular + TypeScript engineer and security-minded reviewer.
+
+Repository context:
+
+- This is an Angular project recreating a Mac OS desktop experience in a web browser using Tailwind CSS.
+- Priorities: maintainability, clarity, performance, and safe-by-default patterns.
+- Keep behavior/UI/UX stable unless you are fixing a clear bug.
+
+Primary goal:
+Do a comprehensive review of the codebase and clean it up: organize, optimize, remove tech debt, align with industry standards, and improve safety/security.
+
+Non-goals / Constraints:
+
+- Do NOT do major framework upgrades (Angular major version, Tailwind major version) unless absolutely necessary; if you believe it’s necessary, document the rationale and stop before applying it.
+- Avoid adding new dependencies unless there’s a strong justification (lint/format/test tooling is allowed if the repo is missing basics, but prefer using existing tooling).
+- Keep refactors incremental and reviewable (small cohesive commits if possible).
+- Do not delete functionality; deprecate or isolate if needed.
+- If you are uncertain whether a change alters runtime behavior, do NOT guess—document the uncertainty and propose a safer alternative.
+
+Workflow (follow in order):
+
+1) Baseline discovery (no code changes yet)
+
+- Read and summarize: package.json scripts, angular.json, tsconfig*, tailwind config, and overall folder layout.
+- Identify how the app is structured (apps/windows/overlays/app manager/etc).
+- Identify quality gates that exist already (lint, format, tests, build).
+- If tool execution is available, run the project’s existing commands (in this order): install (npm ci or npm install), lint, unit tests, build. Record outputs.
+
+2) Produce an “Audit & Plan” before refactoring
+   Create a short plan (bulleted) and categorize findings:
+
+- Quick wins (mechanical / low risk)
+- Medium refactors (worth it but need care)
+- Larger changes (risky; propose but do not implement unless clearly safe)
+  For each item: describe the problem, proposed fix, risk level, and how you’ll validate it.
+
+Pay special attention to these services (review them early and document issues/patterns):
+
+- sound.service.ts
+- user.service.ts
+- overlay.service.ts
+- cli.service.ts
+- typewriter.service.ts
+- settings.service.ts
+- application-manager.service.ts
+- media.service.ts
+- storage.service.ts
+- file-system.service.ts
+- game-config.service.ts
+
+3) Implement improvements (in small, safe steps)
+   Apply the plan with an emphasis on:
+   Code quality & architecture:
+
+- Consistent naming, folder structure, and separation of concerns.
+- Reduce circular dependencies and “god services”.
+- Prefer explicit interfaces/types over `any`.
+- Improve error handling; remove noisy logs; standardize logging if present.
+  Angular & RxJS best practices:
+- Ensure subscriptions don’t leak (use takeUntilDestroyed if available; otherwise a consistent teardown pattern).
+- Avoid nested subscriptions; prefer pipeable operators; handle errors.
+- Avoid direct DOM manipulation; use Angular patterns (Renderer2, sanitization where appropriate).
+  Performance:
+- Avoid heavy synchronous work on the UI thread; debounce/throttle where appropriate.
+- Ensure Tailwind usage is efficient (remove unused classes/duplicates if reasonable).
+  Security / safety review:
+- Check for XSS vectors (innerHTML, bypassSecurityTrust*, DOM insertion).
+- Validate/sanitize any user-controlled inputs (e.g., CLI commands, filenames, “paths”, storage keys).
+- Ensure localStorage/sessionStorage usage is safe and scoped; avoid storing secrets.
+- Run npm audit if available; do NOT blindly “audit fix” if it risks breaking builds—document what you would change.
+
+Validation:
+
+- After each meaningful change, rerun the relevant checks (lint/tests/build).
+- If tests are missing for critical logic, add a minimal set for the riskiest modules/services (prioritize CLI parsing, file-system/storage behaviors, and application/window manager state logic).
+
+4) Create documentation under /docs (required output)
+   Create /docs at the project root (if it doesn’t exist), and organize it into these subfolders:
+
+- /docs/ARCHITECTURE
+- /docs/README
+- /docs/TODOS
+- /docs/FUTURE_FEATURES
+  (If the repository already uses the misspellings “ARCHETECTURE” or “FURTURE_FFEATURES”, match the existing convention, but prefer corrected names for new repos.)
+
+All docs must be Markdown. Create at minimum:
+
+/docs/README/INDEX.md
+
+- A hub that links to every doc below.
+
+/docs/README/PROJECT_OVERVIEW.md
+
+- What this project is, the user experience it recreates, key features.
+- Tech stack summary (Angular + Tailwind + notable libs).
+- Folder/module map and where to start reading the code.
+
+/docs/README/DEVELOPMENT.md
+
+- Setup instructions, common scripts, how to run locally, how to build, how to test, troubleshooting tips.
+
+/docs/ARCHITECTURE/OVERVIEW.md
+
+- System overview and major subsystems (desktop, windows/apps, overlays, settings, storage, media/sound, CLI).
+- Include a Mermaid diagram for high-level architecture (components/services and relationships).
+
+/docs/ARCHITECTURE/SERVICES.md
+
+- A section for each key service listed above:
+  - Responsibility
+  - Key methods/events/observables
+  - Dependencies (what it calls / what calls it)
+  - Risks/footguns
+  - Recommended improvements (and what you implemented)
+
+/docs/ARCHITECTURE/STATE_EVENTS.md
+
+- Explain state management approach, event flows, window/app lifecycle, persistence strategy, and how overlays interact with apps/windows.
+
+/docs/ARCHITECTURE/SECURITY.md
+
+- Threat model relevant to this app (XSS, injection via CLI, unsafe storage, supply chain).
+- Findings + mitigations you applied; remaining risks.
+
+/docs/TODOS/TECH_DEBT.md
+
+- A prioritized checklist of remaining tech debt with impact + effort estimates (S/M/L) and suggested order of operations.
+
+/docs/FUTURE_FEATURES/ROADMAP.md
+
+- A realistic roadmap: short-term enhancements, medium-term refactors, long-term features.
+- Call out dependencies/risks for each.
+
+5) Final output (what you tell me)
+   When finished, respond with:
+
+- A concise summary of what you changed and why (grouped by category).
+- Commands you ran + results (lint/tests/build/audit).
+- A “review checklist” for me to validate changes quickly.
+- Any follow-up items you intentionally did not change (and why).

+# Architecture Overview
+
+## Runtime Shape
+
+The app uses Angular standalone components with route-driven screens and service-centric state.
+
+- Router controls entry screens (home, login, desktop, boot, sleep).
+- Desktop screen coordinates window lifecycle and system UI.
+- Services hold long-lived state (apps, user, settings, storage, CLI, sound, files, notifications).
+- Dynamic component loading is used for in-window apps.
+
+## Major Subsystems
+
+- Desktop shell:
+  desktop surface, tray, dock, route params, context menu.
+- Window/app manager:
+  app registry, app launch, focus, close, persisted open apps.
+- CLI gameplay:
+  command execution, typewriter output, user/level progression.
+- Persistence:
+  settings/user/tasks/patches through storage strategy.
+- Media/audio:
+  icon/media helpers, sound playback, music and effects.
+- Overlay and notifications:
+  global overlays and in-app notification stream.
+
+## High-Level Diagram

+
+## Design Notes
+
+- This codebase favors behavior in services over local component state.
+- The primary maintainability pressure points are large services with mixed responsibilities and untyped dynamic data flows.
+- Behavior stability depends heavily on preserving service public APIs while tightening internals.

+# Security Notes
+
+## Threat Model (Relevant to This App)
+
+- XSS via dynamic HTML rendering (`innerHTML`, dynamic tooltip/notification content, terminal output).
+- Open redirect or unsafe external navigation from route-driven URL values.
+- Client-side secret exposure (API keys in browser bundle/environment files).
+- Unsafe parsing and persistence of local storage data.
+- Supply-chain risk from dependency drift and failing quality gates.
+
+## Audit Findings
+
+## 1) XSS Surface
+
+Current sinks include:
+
+- CLI output rendering with `[innerHTML]`
+- notification message rendering with `[innerHTML]`
+- tooltip text rendering with `[innerHTML]`
+- raw `innerHTML` writes in settings subpanel fallback
+- SVG trust bypass via `bypassSecurityTrustHtml`
+
+Risk:
+user-controlled or remotely controlled strings could execute markup/script payloads if not constrained.
+
+## 2) External URL Handling
+
+- Redirect guard opens decoded route param in a new tab with no allowlist.
+
+Risk:
+malicious URLs or script schemes can be triggered by crafted routes.
+
+## 3) Secrets in Client
+
+- OpenAI and weather API keys are configured for client-side use.
+
+Risk:
+keys are recoverable from browser context and can be abused.
+
+## 4) Storage Trust
+
+- App/session state read from local storage without robust schema validation.
+
+Risk:
+tampered storage payloads can produce runtime errors or unintended behavior.
+
+## Recommended Mitigations (Planned)
+
+1. Replace unsafe HTML sinks with safe rendering primitives and explicit formatting tokens.
+2. Validate external URLs with strict scheme/domain checks before `window.open`.
+3. Move third-party API calls requiring secrets behind a backend proxy/function.
+4. Add schema guards for storage rehydration and fail-safe defaults.
+5. Reduce `bypassSecurityTrust*` usage to controlled, immutable asset paths only.
+
+## Operational Notes
+
+- Firebase database rules are present; keep auth checks strict and avoid widening `.read` scopes.
+- Use supported Node LTS for reproducible builds and security patch coverage.

+# Core Services
+
+This section focuses on the key game/runtime services prioritized in the cleanup audit.
+
+## `sound.service.ts`
+
+- Responsibility:
+  effect audio preload/playback/mute and variant pools.
+- Dependencies:
+  `SettingsService`, `PatchService`, `LogService`, sound config token.
+- Called by:
+  desktop flow, CLI/typewriter, login, intro overlays.
+- Current risks:
+  service `OnInit` lifecycle not invoked by Angular DI, weak filename sanitization, cache key inconsistency.
+- Planned cleanup:
+  move init to explicit constructor/init method, harden filename allowlist, normalize cache keys.
+
+## `user.service.ts`
+
+- Responsibility:
+  user profile state and persistence bridge.
+- Dependencies:
+  `SettingsService`, `LogService`.
+- Called by:
+  login, desktop, CLI, settings, game config, tray.
+- Current risks:
+  `previousUserSubject` not updated, unnecessary async wrapper around sync settings call.
+- Planned cleanup:
+  simplify update path, ensure previous/current snapshots are coherent.
+
+## `overlay.service.ts`
+
+- Responsibility:
+  global overlay image visibility/state.
+- Dependencies:
+  none.
+- Called by:
+  desktop and overlay component.
+- Current risks:
+  temporary overlay timeout races and no timeout tracking.
+- Planned cleanup:
+  track/cancel previous timers and provide deterministic hide behavior.
+
+## `cli.service.ts`
+
+- Responsibility:
+  command registry and command execution.
+- Dependencies:
+  `GameConfigService`, `UserService`.
+- Called by:
+  CLI game component.
+- Current risks:
+  auth bug in `su` command (`isAuthorized` not invoked), direct `localStorage` reads, weak input validation.
+- Planned cleanup:
+  fix auth branch, route identity through `UserService`, validate command parameters.
+
+## `typewriter.service.ts`
+
+- Responsibility:
+  queued typed output with mode-dependent sound behavior.
+- Dependencies:
+  `SoundService`, `UserService`.
+- Called by:
+  CLI, desktop intro, home terminal.
+- Current risks:
+  loose typings (`any`), timer lifecycle concerns, `onBegin` called per char instead of per line.
+- Planned cleanup:
+  strict event payload types, line-level hook semantics, safer timer teardown.
+
+## `settings.service.ts`
+
+- Responsibility:
+  register/get/update single settings and setting sets, form sync.
+- Dependencies:
+  `StorageService`, `NotificationService`.
+- Called by:
+  user, weather, sound player, appearance panel, patch/music features.
+- Current risks:
+  broad `any` typing, untracked subscriptions, nested persistence flows.
+- Planned cleanup:
+  type-safe setting models, explicit subscription lifecycle, flatten async logic.
+
+## `application-manager.service.ts`
+
+- Responsibility:
+  app registry, launch/close/focus, memory checks, persistence of open apps.
+- Dependencies:
+  `ApplicationFactory`, `NotificationService`, `LogService`.
+- Called by:
+  desktop, dock, tray, app window template, activity monitor, CLI.
+- Current risks:
+  very large mixed-responsibility service, unsafe `localStorage` JSON parse, fragile instance counting.
+- Planned cleanup:
+  extract persistence/registry helpers, guard JSON parse, fix instance limit accounting.
+
+## `media.service.ts`
+
+- Responsibility:
+  media item helpers and basic preload behavior.
+- Dependencies:
+  none.
+- Called by:
+  notification/media rendering pathways.
+- Current risks:
+  weak typing around icon/svg data and inconsistent factory outputs.
+- Planned cleanup:
+  normalize `MediaItem` factory return types and tighten icon interfaces.
+
+## `storage.service.ts`
+
+- Responsibility:
+  persistence abstraction (`IndexedDB` first, localStorage fallback).
+- Dependencies:
+  browser storage APIs.
+- Called by:
+  settings, tasks, patch editor.
+- Current risks:
+  `getAllKeys()` bypasses strategy and always reads localStorage.
+- Planned cleanup:
+  add strategy-level key enumeration and align behavior across storage backends.
+
+## `file-system.service.ts`
+
+- Responsibility:
+  virtual file tree, path navigation, finder data/view modes.
+- Dependencies:
+  `HttpClient`, faker.
+- Called by:
+  finder UI and tray view mode controls.
+- Current risks:
+  startup faker generation cost, nondeterministic tree shape, duplicate favorites.
+- Planned cleanup:
+  deterministic seed or static mock loading in prod, dedupe favorites, lazy/mock gate.
+
+## `game-config.service.ts`
+
+- Responsibility:
+  level loading, current level state, unlocked commands, log file content lookup.
+- Dependencies:
+  `HttpClient`, `UserService`.
+- Called by:
+  CLI service, level loader, CLI component.
+- Current risks:
+  awkward `Promise<Observable<...>>` API, unused parameters, fragile level load expectations.
+- Planned cleanup:
+  return clean observables/promises (one async model), remove unused args, tighten level indexing.

+# State and Event Flow
+
+## State Management Model
+
+This codebase uses service-local reactive state (mostly `BehaviorSubject`) instead of a central state library.
+
+- Long-lived state:
+  app registry/open apps/focus, user profile, settings, file system, notifications.
+- Component-local state:
+  UI toggles, view pagination, current selected items.
+- Persistence:
+  settings/user/tasks/patches via `StorageService`.
+
+## Core Event Flows
+
+## App and Window Lifecycle
+
+1. Desktop requests open app via `ApplicationManagerService.openApplication(id)`.
+2. Manager validates registry, memory, and instance limits.
+3. `ApplicationFactory` creates window instance metadata.
+4. `AppWindowComponent` dynamically creates embedded component.
+5. Focus updates reorder open apps list and tray state.
+6. Open app list is persisted to local storage key `applications`.
+
+## CLI Command Flow
+
+1. User enters command in CLI app.
+2. `CliGameComponent` normalizes input and invokes `CLIService.executeInput`.
+3. Command output is routed to `TypewriterService`.
+4. Follow-up actions can mutate user/level state through `UserService` and `GameConfigService`.
+
+## User and Settings Persistence Flow
+
+1. `UserService` registers/reads `user` setting set.
+2. Updates flow through `SettingsService.updateSettingSet`.
+3. `SettingsService` persists through `StorageService` strategy.
+
+## Overlay and Notification Flow
+
+1. Any producer calls `OverlayService` or `NotificationService`.
+2. Overlay and notification renderer components subscribe and update UI.
+3. Notifications auto-dismiss on timeout unless duration is zero.
+
+## Hotspots for Cleanup
+
+- Unbounded subscriptions in services/components that do not use `takeUntilDestroyed`.
+- Dynamic window/component lifecycle depends on mutable shared objects.
+- App persistence uses raw object snapshots and should be narrowed to safe fields.

+# Roadmap
+
+## Short-Term (1-2 Sprints)
+
+- Re-enable trustworthy quality gates (lint, real test execution, stable build environment).
+- Fix high-risk correctness and security bugs identified in audit.
+- Add targeted tests around CLI parsing/auth, app manager lifecycle, and storage rehydration.
+
+Dependencies:
+
+- Supported Node runtime for reproducible builds.
+- Stable lint config path.
+
+Risks:
+
+- Existing script/config drift may hide real code issues until gates are repaired.
+
+## Medium-Term (2-4 Sprints)
+
+- Service decomposition:
+  split `ApplicationManagerService` and simplify `SettingsService`.
+- Strong typing pass:
+  remove high-impact `any` usage in service contracts and dynamic payloads.
+- Performance cleanup:
+  reduce startup random generation and avoid avoidable subscription churn.
+
+Dependencies:
+
+- Baseline tests in key services/components.
+
+Risks:
+
+- Refactor can affect runtime sequencing in desktop/window lifecycle if done too broadly.
+
+## Long-Term (4+ Sprints)
+
+- Security hardening:
+  migrate secret-bearing API calls to backend proxy.
+- Rendering safety:
+  remove risky `innerHTML` patterns in terminal/tooltip/notification systems.
+- Product evolution:
+  richer app ecosystem, saved desktop sessions, advanced window tiling/layout presets.
+
+Dependencies:
+
+- Backend support for proxy endpoints and auth/rate-limiting.
+
+Risks:
+
+- UI behavior drift during renderer hardening unless covered by tests and visual checks.

+# Development
+
+## Prerequisites
+
+- Node.js LTS (recommended: Node 20 or Node 22)
+- npm 10+
+- Chrome/Chromium for Karma tests
+
+Current environment note: Node `23.11.1` is unsupported by Angular 19 and currently causes unstable build behavior in this repository.
+
+## Install
+
+```bash
+npm ci
+```
+
+## Environment Setup (Local)
+
+1. Copy `src/environments/.env.example` to `src/environments/.env.local`.
+2. Fill in your local values.
+3. Keep `src/environments/.env.local` and `src/environments/environment.local.ts` uncommitted.
+
+## Run Locally
+
+```bash
+npm start
+```
+
+## Build
+
+```bash
+npm run build
+```
+
+## Test
+
+```bash
+npm run test -- --watch=false --browsers=ChromeHeadless
+```
+
+## Lint
+
+```bash
+npm run lint
+```
+
+## Current Quality Gate Status (Audit Baseline)
+
+- `npm ci`: not re-run in this pass (existing `node_modules` reused)
+- `npm run lint`: runs and reports real issues (`372` current errors)
+- `npm run test -- --watch=false --browsers=ChromeHeadless`: passing (`88/88`)
+- `npm run build`: still aborts early under unsupported Node `23.11.1`
+
+## Recommended Local Tooling Alignment
+
+1. Use Node `22` (or any version matching `package.json#engines`).
+2. Run `nvm use` (project now includes `.nvmrc`).
+3. Continue reducing lint backlog from current baseline.
+
+## Troubleshooting
+
+- If test fails with port binding in sandboxed environments, run with elevated permissions or locally in non-sandbox shell.
+- If Angular CLI prompts for analytics in CI/local automation, set:
+  - `NG_CLI_ANALYTICS=false`
+- If build crashes with memory allocator errors, switch to supported LTS Node first before code-level debugging.

+  - `src/environments/.env.local`
+- Do not commit those files.
+- Use `src/environments/.env.example` as the safe template.
+
+## CI Environment Generation
+
+CI runs:
+
+```bash
+npm run generate:env
+```
+
+This script writes:
+
+- `src/environments/environment.ts`
+- `src/environments/environment.prod.ts`
+
+Both are generated from CI environment values before `npm run build`.

+# Project Overview
+
+## What This Project Is
+
+This project recreates a macOS-inspired desktop experience in the browser using Angular and Tailwind CSS. It mixes a portfolio-style landing experience with an interactive in-browser "OS" that includes movable windows, app launching, CLI-like gameplay, notifications, overlays, and media tools.
+
+## Core Experience
+
+- Desktop shell with app windows and focus management.
+- App registry and launcher behavior (dock/system tray/menu).
+- CLI-driven game flow with typed output and level progression.
+- Settings, storage, and user profile persistence.
+- Audio, media rendering, and visual overlay systems.
+
+## Tech Stack
+
+- Angular 19 standalone components
+- TypeScript (strict mode enabled)
+- Tailwind CSS 3
+- RxJS for reactive state/event streams
+- AngularFire/Firebase for backend integration points
+- FontAwesome and CDK helpers in UI components
+
+## High-Level Module Map
+
+- `src/app/components/main`:
+  public/portfolio-facing experience.
+- `src/app/components/game`:
+  desktop simulation, apps, system UI, and most game services.
+- `src/app/components/game/services`:
+  core runtime logic (app manager, CLI, settings, storage, media, sound, user).
+- `src/app/services`:
+  shared Firebase/auth services.
+- `src/app/guards`, `src/app/pipes`, `src/app/modules`:
+  route guards, pipe helpers, feature modules.
+
+## Suggested Reading Order
+
+1. `src/app/app.routes.ts`
+2. `src/app/app.config.ts`
+3. `src/app/components/game/desktop/desktop.component.ts`
+4. `src/app/components/game/services/application-manager.service.ts`
+5. `src/app/components/game/apps/cli-game/cli-game.component.ts`
+6. `src/app/components/game/services/*` for subsystem behavior

+# Tech Debt TODOs
+
+Status legend:
+
+- `[ ]` not started
+- `[~]` in progress
+- `[x]` complete
+
+## Quick Wins (Do First)
+
+- [x] Fix lint gate wiring (`npm run lint` currently non-functional).
+  - Impact: High
+  - Effort: S
+  - Validation: lint command runs and reports real issues.
+
+- [x] Fix test script include pattern so specs are discovered (currently 0 tests executed).
+  - Impact: High
+  - Effort: S
+  - Validation: test command executes existing specs.
+
+- [x] Fix `CLIService` auth bug in `su` command path.
+  - Impact: High
+  - Effort: S
+  - Validation: CLI command behavior tests/manual checks.
+
+- [x] Fix notification dismiss/click behavior to use notification `id` consistently.
+  - Impact: Medium
+  - Effort: S
+  - Validation: notification component spec/manual UX check.
+
+- [x] Add URL validation allowlist in redirect guard.
+  - Impact: High
+  - Effort: S
+  - Validation: guard unit tests for allowed and blocked URLs.
+
+- [x] Stabilize baseline unit tests to full pass (`88/88` in CI-like headless run).
+  - Impact: High
+  - Effort: M
+  - Validation: `npm run test -- --watch=false --browsers=ChromeHeadless`.
+
+## Medium Refactors
+
+- [~] Refactor `SettingsService` for typed models and safe subscription lifecycle.
+  - Impact: High
+  - Effort: M
+  - Validation: lint/test/build + settings UI regression check.
+
+- [x] Optimize `ScrollClassToggleDirective` scroll handling by batching with `requestAnimationFrame` and caching class lists.
+  - Impact: Medium
+  - Effort: S
+  - Validation: manual scroll regression across main page header transitions.
+
+- [x] Move `PatchEditorComponent` inline template styles into component stylesheet.
+  - Impact: Low
+  - Effort: S
+  - Validation: visual regression check for patch envelope controls.
+
+- [x] Align `StorageService` strategy behavior, including `getAllKeys`.
+  - Impact: Medium
+  - Effort: M
+  - Validation: storage-focused unit tests across strategy paths.
+
+- [~] Break `ApplicationManagerService` into smaller responsibilities (registry, persistence, lifecycle).
+  - Impact: High
+  - Effort: M
+  - Validation: app launch/focus/close regression tests.
+
+- [~] Stabilize `TypewriterService` timer and callback semantics.
+  - Impact: Medium
+  - Effort: M
+  - Validation: CLI typing flow checks and queue behavior tests.
+
+- [~] Reduce startup randomness/cost in `FileSystemService`.
+  - Impact: Medium
+  - Effort: M
+  - Validation: finder behavior and startup responsiveness.
+
+## Larger Changes (Riskier, Stage Later)
+
+- [ ] Move OpenAI and weather calls behind backend proxy/functions.
+  - Impact: High (security)
+  - Effort: L
+  - Validation: integration tests and production key removal.
+
+- [ ] Replace `innerHTML` rendering paths with safe renderers.
+  - Impact: High (security)
+  - Effort: L
+  - Validation: XSS regression tests + UI snapshot/manual checks.
+
+- [~] Enforce supported Node LTS through `.nvmrc`/`engines` and CI checks.
+  - Impact: Medium
+  - Effort: S
+  - Validation: consistent local/CI build success.
+
+## Suggested Execution Order
+
+1. Restore quality gates (lint/test/build reliability).
+2. Patch clear correctness/security bugs.
+3. Refactor high-impact services incrementally.
+4. Address secret-handling and HTML-rendering hardening.
