# Product Guidelines: Manual Slop

## Documentation Style

- **Strict & In-Depth:** Documentation must follow an old-school, highly detailed technical breakdown style (similar to VEFontCache-Odin). Focus on architectural design, state management, algorithmic details, and structural formats rather than just surface-level usage.

## UX & UI Principles

- **USA Graphics Company Values:** Embrace high information density and tactile interactions. 
- **Professional Arcade Aesthetics:** Balances high-energy "Arcade" feedback (blinking notifications, tactile updates) with a "Professional" visual discipline. Employs modern typography (Inter/Maple Mono), subtle rounded geometry, and soft shadows to ensure the tool feels like a sophisticated, expert utility. Includes a high-density **NERV Technical Console** theme option for maximum focus and CRT-inspired visual feedback.
- **Rich Text Readability:** Prioritizes legibility of AI communications and technical logs by utilizing GitHub-Flavored Markdown and integrated syntax highlighting. This ensures that complex code fragments and structured data are immediately accessible and professionally presented.
- **Explicit Control & Expert Focus:** The interface should not hold the user's hand. It must prioritize explicit manual confirmation for destructive actions while providing dense, unadulterated access to logs and context.
- **Multi-Viewport Capabilities:** Leverage dockable, floatable panels to allow users to build custom workspaces suitable for multi-monitor setups.

## Code Standards & Architecture

- **Data-Oriented & Immediate Mode Heuristics:** Align with the architectural values of engineers like Casey Muratori and Mike Acton. 
  - **The "Less Python Does, the Better" Rule:** Python should act primarily as a procedural semantic definer (similar to how ImGui defines a UI DAG), delegating heavy lifting to efficient data structures, vectorized operations, or lower-level primitives.
  - Minimize Python JIT overhead by favoring bulk data processing over fine-grained object-oriented manipulation.
  - The GUI (`gui_2.py`) must remain a pure visualization of application state. It should not *own* complex business logic or orchestrator hooks (strive to decouple the 'Application' controller from the 'View').
  - Treat the UI as an immediate mode frame-by-frame projection of underlying data structures.
  - Optimize for zero lag and never block the main render loop with heavy Python JIT work.
  - Utilize proper asynchronous batching and queue-based pipelines for background AI work, ensuring a data-oriented flow rather than tangled object-oriented state graphs.
- **Strict State Management:** There must be a rigorous separation between the Main GUI rendering thread and daemon execution threads. The UI should *never* hang during AI communication or script execution. Use lock-protected queues and events for synchronization.
- **Comprehensive Logging:** Aggressively log all actions, API payloads, tool calls, and executed scripts. Maintain timestamped JSON-L and markdown logs to ensure total transparency and debuggability.
- **Mandatory ImGui Verification:** All changes to the GUI (`gui_2.py`) MUST be verified using the custom AST linter (`scripts/check_imgui_scopes.py`) to ensure all ImGui scopes (begin/end, push/pop) are properly matched. Developers should prioritize the use of `src/imgui_scopes.py` context managers (`imscope`) over manual push/pop calls.
- **Modular Controller Pattern:** To prevent "God Object" bloat in core controllers (like `AppController`), all state-independent or utility logic must be moved to module-level functions. Functions requiring class state should accept the instance as an explicit dependency (`def logic(controller: AppController, ...)`). Massive `if/elif` dispatch blocks must be refactored into handler maps (dictionaries) of module-level functions.
- **UI Delegation for Hot-Reload:** All complex ImGui rendering logic must be extracted from the `App` class into module-level functions named `render_xxx(app: App)`. The `App` class should only contain thin delegation wrappers (`def _render_xxx(self): render_xxx(self)`). This architecture is mandatory for supporting state-preserving hot-reloads of the UI logic.
- **Dependency Minimalism:** Limit external dependencies where possible. For instance, prefer standard library modules (like `urllib` and `html.parser` for web tools) over heavy third-party packages.

## Phase 5: Heavy Curation & Structural Integrity (MANDATORY)

- **Intensive System Analysis:** Align with the standards of low-level systems engineers (Fleury, Acton, Muratori, Blow). Do not accept high-level abstractions as sufficient documentation.
- **Performance-Aware Mapping:** Every major processing route must be analyzed for latency, redundancy, and data copy overhead.
- **Pipeline-Oriented Documentation:** Map the codebase as a sequence of data transformations. Identify exactly where data enters, how it is mutated, and where it exits.
- **Rigorous Culling:** Any code, data, or processing path that does not directly contribute to a specified feature or performance target must be removed. 
- **Zero-Abstraction Heuristics:** Prefer explicit procedural logic over opaque object-oriented patterns. Ensure state transitions are traceable and deterministic.

## AI-Optimized Compact Style

- **Indentation:** Exactly **1 space** per level. This minimizes token usage in nested structures.
- **Newlines:** Maximum **one (1)** blank line between top-level definitions. **Zero (0)** blank lines within function or method bodies.
- **Vertical Compaction:** Use single-line `if` statements, semicolon-separated framework calls (`imgui.same_line(); imgui.text(...)`), and aligned assignments to aggressively minimize vertical line counts. **Note:** Function and method definition signatures (`def ...:`) must ALWAYS remain on their own isolated lines.
- **Region Blocks:** Use `#region: Name` and `#endregion: Name` to logically organize massive files that cannot be easily broken apart without increasing context load.
- **Type Hinting:** Mandatory, strict type hints for all parameters, return types, and global variables to ensure high-signal context for AI agents.
- **Structural Dependency Mapping (SDM):** All major state variables, methods, and functions MUST include terse dependency tags at the end of their docstrings for AI-assisted impact analysis.
  - **Functions/Methods:** `[C: Caller1, Caller2]` (Primary callers).
  - **State Variables:** `[M: File:Line, Method]` (Mutation points) and `[U: File]` (Major use paths).

## Testing Requirements

These are the process standards the project's test infrastructure enforces. For the full implementation contract (fixture names, anti-patterns, audit scripts), see [docs/guide_testing.md §Structural Testing Contract](../docs/guide_testing.md) and the per-styleguide audit scripts in [code_styleguides/](code_styleguides/).

- **Structural Testing Contract:** Ban on arbitrary core mocking with `unittest.mock.patch` (unless explicitly authorized for a specific boundary test). All integration and end-to-end testing must use the `live_gui` fixture to interact with a real instance of the application via the Hook API. Bypassing the hook server to directly mutate GUI state in tests is prohibited. All test-generated artifacts (logs, temporary workspaces, mock outputs) MUST be written to `tests/artifacts/` or `tests/logs/` (gitignored).
- **Isolated-Pass Verification Fallacy (Added 2026-06-10):** A test that "passes when run after test X but fails in isolation" is a **fragile test, not a fragile fixture**. The flip side is also true: a test that "passes in isolation but fails in batch" is failing — its failure is masked by isolation. The only verification that matters for `live_gui` tests (or any test that depends on shared subprocess state) is the **batch run** in the suite the test will ship in. Do NOT commit a fix that has only been verified in isolation. The 4-day test-hell saga of 2026-06-06 to 2026-06-10 was the result of agents committing fixes after isolated passes; the bisect required both directions and was only caught at the suite-level batch green on 2026-06-10. See [docs/reports/test_infrastructure_hardening_batch_green_20260610.md](../docs/reports/test_infrastructure_hardening_batch_green_20260610.md) for the full incident.
- **Audit Scripts as CI Gates:** The 4 audit scripts (`check_test_toml_paths.py`, `audit_main_thread_imports.py`, `audit_weak_types.py`, `audit_no_models_config_io.py`) enforce the conventions above. They run as pre-commit/CI gates and exit non-zero on regression. New conventions must be paired with a new audit script per [conductor/workflow.md §Audit Script Policy](workflow.md).
- **Skip Markers Are Documentation, Not Avoidance:** `@pytest.mark.skip(reason=...)` is a record of a known failure, not an escape from fixing the underlying bug. Skip markers are valid for opt-in integration tests (require external resources, env-var-gated) or features behind a feature flag. They are NOT valid for pre-existing failing tests, tests the agent doesn't understand, or racy assertions the agent doesn't want to debug. When you add a skip, document the underlying issue in `reason=` and commit with a follow-up note. See [conductor/workflow.md §Skip-Marker Policy](workflow.md).
