# Implementation Summary

**Session ID**: `phase34-session02-accessibility-and-compact-input` **Completed**: 2026-06-26 **Duration**: 1 hour

***

## Overview

Completed Phase 34 Session 02 by fixing the AI Rogue accessibility and compact input blocker set. The Play runtime now exposes the render summary through a screen-reader live region, compact users can trigger Inspect and Next target via the existing touch dispatch path, and Large HUD Labels has a real bounded runtime projection effect. The session preserved explicit opt-in posture and browser-local public-demo behavior.

## Technical Decisions

1. **Renderer-to-React summary bridge**: Emitted render summaries on meaningful runtime frame/gameplay events so Pixi remains the canvas owner and React owns DOM accessibility.
2. **Existing command path reuse**: Wired compact Inspect and Next target through `dispatchCommand(command, "touch")` to avoid a parallel input contract.
3. **Bounded Large HUD projection**: Implemented Large HUD Labels at the render-model boundary with deterministic dimensions and coordinate bounds instead of only changing settings copy.

| Lint                   | PASS                    |
| Format check           | PASS                    |
| Coverage               | Not collected           |

## Lessons Learned

1. Assistive runtime state should be derived from the existing render summary and emitted through the runtime bridge, not scraped from Pixi internals.
2. Compact input coverage needs to prove both active touch dispatch and keyboard-mode disabled behavior to avoid accidental duplicate or unavailable commands.

***

## Future Considerations

Items for future sessions:

1. Session 03 should continue with simulation correctness and production scenario gate remediation.
2. Later renderer lifecycle and performance sessions should preserve the screen-reader summary contract while reducing hot-loop work.

## 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/phase34-session02-accessibility-and-compact-input/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.
