# Implementation Summary

**Session ID**: `phase35-session07-renderer-and-react-bridge-refactor` **Completed**: 2026-06-26 **Duration**: 1 hour

***

## Overview

Session 07 completed the behavior-preserving AI Rogue renderer, effects, render-model, audio adapter, and React runtime bridge refactor. The public runtime barrel stayed narrow, runtime/product behavior was preserved, and the session closed with validation PASS evidence across focused unit tests, broad AI Rogue tests, full Vitest, runtime/mobile Playwright, typecheck, lint, format, ASCII/LF, security, GDPR applicability, and product-surface checks.

## Technical Decisions

1. **Keep the public runtime barrel narrow**: `runtime/index.ts` still exports only the mounted runtime entrypoint so internal renderer, effects, render-model, and React bridge helpers do not become public API.
2. **Extract behavior owners before changing call sites broadly**: Scheduler, state, save, sprite, layer, inspect, audio, HUD, viewport, persistence, and control responsibilities moved into cohesive files while tests preserved the existing behavior contracts.
3. **Keep diagnostics off the product surface**: Runtime event diagnostics stay hidden and `aria-hidden`, while assistive summaries remain the exposed accessibility status surface.

## Test Results

| Metric                    | Value                            |
| ------------------------- | -------------------------------- |
| Focused renderer suite    | 50 passed                        |
| Focused AI Rogue suite    | 257 passed                       |
| Full Vitest               | 4369 passed                      |
| Runtime/mobile Playwright | 14 Chromium tests passed         |
| Typecheck/lint/format     | PASS                             |
| Coverage                  | Not reported by invoked commands |

***

## Lessons Learned

1. Markdown evidence tables that contain shell pipelines are fragile; bullet ledgers are safer for validation command evidence.
2. Hidden diagnostics need direct regression coverage so product UI remains user-facing while tests can still inspect runtime events.
3. Renderer refactors are safer when cache ownership, sprite cleanup, and route cleanup are characterized before moving modules.

***

## Future Considerations

Items for future sessions:

1. Session 08 should preserve the narrowed renderer and React bridge boundaries while cleaning world types and fixture ownership.
2. Session 09 should use this validation evidence while syncing docs around current renderer, media, and runtime behavior.
3. Session 10 should include these split modules in the final release-gate evidence matrix.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://ai-os-and-trend-finder.gitbook.io/ai-os-and-trend-finder-docs/.spec_system/archive/sessions/phase35-session07-renderer-and-react-bridge-refactor/implementation_summary.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
