# Implementation Summary

**Session ID**: `phase30-session07-play-runtime-integration` **Completed**: 2026-06-22 **Duration**: 1 hour

***

## Overview

Session 07 turned the AI Rogue foundation into the first playable runtime slice. The Play route now renders deterministic simulation snapshots with committed gameplay and UI atlas frames, accepts keyboard and pointer controls, supports pause, resume, reset, save, load, win, loss, and run-complete events, records bounded run summaries, and exposes one wallet-backed `Integrity Patch` loadout upgrade through browser-local persistence.

## Technical Decisions

1. **Snapshot projection before PixiJS mutation**: Runtime draw state is derived in a pure render model, keeping simulation rules testable and renderer code focused on texture and sprite lifecycle.
2. **One bounded upgrade first**: `Integrity Patch` satisfies the first spendable-upgrade requirement without preempting Session 08 progression depth.
3. **Schema-backed save slots**: Runtime saves persist a bounded serialized simulation envelope instead of PixiJS objects, DOM state, raw prompts, logs, or private paths.
4. **Local transaction boundary**: Upgrade debit and ledger writes happen through the browser-local persistence layer with duplicate-trigger guards.

## Test Results

| Metric                  | Value                       |
| ----------------------- | --------------------------- |
| Full Vitest             | 3975/3975 passed            |
| Focused AI Rogue Vitest | 94/94 passed                |
| Focused Playwright      | 6/6 passed                  |
| Typecheck               | Passed                      |
| Asset Size Check        | Passed                      |
| Coverage                | Not collected in validation |

## Lessons Learned

1. Frame-level atlas validation caught asset/runtime vocabulary issues early while preserving the lazy PixiJS boundary.
2. Save-slot reads need to merge partial IndexedDB records over defaults so a single saved slot survives refresh without requiring every slot to exist.
3. Terminal gameplay event summaries should include win/loss status so browser tests and visible user state can distinguish completed outcomes.

***

## Future Considerations

Items for future sessions:

1. Expand progression with classes, relic catalogs, enemies, and deeper AI OS-flavored resource loops in Session 08.
2. Add mobile-first layout, pointer polish, and optional content/audio decisions in Session 09.
3. Run the full Phase 30 enablement gate set, including build, lint, format, bundle budget, private-artifact checks, and final enablement decision in Session 10.

## 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/phase30-session07-play-runtime-integration/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.
